Shi, Zijun. "Airport charge, traffic volume and car rental price : empirical evidence at US airports". Thesis, University of British Columbia, 2014. http://hdl.handle.net/2429/48604.
Testo completoAbstract (sommario):
This paper examines the interaction among airport aeronautical charge, traffic volume, and car rental service charge by employing a cross-section dataset covering 337 airports in the United States. Other determinants of the aeronautical charge are also examined. Using the method of three stage least squares, the main empirical findings are: (1) Car rental price has no significant impact on passenger volume, indicating that rental cost, which is an important cost category of airport concessional goods, does not affect passenger volume of airport. (2) Car rental price has no significant effect on aeronautical charge. (3) Only rental price at airports with a very low transfer rate responds positively to passenger volume. Overall, rental price does not respond to passenger volume or aeronautical charge. (4) Aeronautical charge has a significant negative effect on passenger volume, but it has no significant effect on car rental price.Business, Sauder School of

wood, warren. "A Look at How Timing Affects Price of Used Car Auctions on eBay Motors". Scholarship @ Claremont, 2015. http://scholarship.claremont.edu/cmc_theses/1079.
Testo completoAbstract (sommario):
This study looked at 7194 completed listing from eBay Motors. Each observation contained a make, model, year, mileage, seller feedback rating, selling price, time of day ended, day of the week auction ended, auction duration, number of bidders, and number of bids for a car that had been sold on eBay Motors between March 16th and April 5th. Using this information this study looked at how timing affected the selling price of each vehicle, while holding the other variables constant. The observations are split up into four different time periods of the day (times are in Pacific Standard Time): morning (3am-8:59pm), midday (9am-2:59pm), evening (3pm-8:59pm), and night (9pm-2:59am). The regression results show that the midday time period increases the selling price of the vehicle by an average of $1445.41 for this data set. This is likely because the demand and supply side of the eBay Motors market are most equivalent during this time period compared to the other time periods.

Testo completoAbstract (sommario):
This paper studies the effects of auction mechanisms on the average price of auction results of Shanghai car license plate from 2004 to 2018. We construct two linear regression models and find that an iterated multi-unit auction has a lower efficiency than a seal-bid discriminatory multi-unit auction. We also find that the pre-set price-ceiling is positively correlated with the average winning price. These results suggest that the government can potentially manipulate auction results through the design of the auction mechanism, and through the setting of warning price as a price ceiling.

Testo completoAbstract (sommario):
The thesis is focused on verifying the pro-cyclical relationship of sales of new passenger cars in the Czech Republic and Slovakia and the subsequent evaluation of the impact of macroeconomic variables in the period from the first quarter of 2005 to the third quarter of 2015. In total, there are four different models estimated of multiple linear regressions of car sales, where for the Czech R. the estimation of different sectors of households and firms is available as well. By comparing the Czech R. and Slovakia regarding aggregate sales, fuel prices and gross domestic products are especially crucial and the pro-cyclical relationship is successfully verified. The economic crisis at the turn of 2008-2009 hit especially Slovakia, while the effect in the Czech R. was offset by a positive shock to fuel prices. For the model of households the procyclical relationship is denied unlike from the model of firms, shock to GDP therefore only deviate sales to firms. For Czech R. is also confirmed a significant relationship of the sales with interest rate or population growth.

Al, Rahahleh Naseem. "Analyzing frequent acquires in emerging markets and futures markets linkage". ScholarWorks@UNO, 2009. http://scholarworks.uno.edu/td/915.
Testo completoAbstract (sommario):
The first chapter of this dissertation examines the returns to frequent acquirers from emerging markets and analyzes the cross-country variations in cumulative abnormal returns. The sample consists of 5,147 transactions carried out by firms from 17 common and civil-law countries during the period of January 1985 to June 2008. I find that the cumulative abnormal returns decline over the deal order and it is more pronounced in civil-law countries than in common-law countries. There is also evidence that the premiums paid by acquirers from civillaw countries with a first successful acquisition are higher than those from common-law countries. These findings are consistent with agency problems and the hubris hypothesis, first introduced by Roll (1986). The second chapter examines the information links across futures markets in different nations, using Vector Autoregressive (VAR)-Dynamic Conditional Correlation (DCC) model. The data comprise a large set of commodity and financial futures traded in U.S., U.K., China, Japan, Canada, and Brazil during the period from August 1998 to December 2008. The primary finding is that market interactions are relatively high for commodities for which information production generally is more diverse (metal commodities), while moderate for commodities for which information is more concentrated (agricultural commodities). Furthermore, the strength and persistence of interactions among futures markets decline after excluding the most informative markets. These findings indirectly support the breadth of information being a relevant factor in the extent of information linkage. The results also indicate that the dynamic correlation in futures markets is high in most commodity and financial futures if there is a significant bi-directional return and volatility spillover. Additionally, I estimate a market’s contribution to the price discovery process. In general, the market that has a stronger price impact and a stronger volatility spillover tends to be the market that has greater contribution or leadership in price discovery.

Fuentes, Andrés. "Abolishing Stockholm’s Public Transport Fares". Thesis, Uppsala universitet, Institutionen för geovetenskaper, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-332459.
Testo completoAbstract (sommario):
The decrease of car emission levels has stagnated in the latter years in Stockholm, Sweden. Since the city’s publictransit system is highly developed via its large access to areas located in the city’s outskirts, it could serve as a tool topartially replace the city's car traffic and reduce emissions. This study therefore aims to examine expected travelbehavior changes from a fare-free public transport system and investigate potential limitations when increasing thepublic transport travel degree in Stockholm. The theoretical background consists of the mode choice theory thatdissects the reasons behind travel habits, and the zero-price effect which explains the effects from abolishing priceswhen purchasing a service product. The methodological approach was conducted through a random probabilitysurvey conducted in a face-to-face mix mode survey interviews in outdoor environments and via computer-assistedtelephone interviewing. The data was then analyzed through MS Excel and SPSS to extract patterns and correlations.The results thereafter implicated preferences from the survey participants implying their desire to primarily reduce orabolish the public transport fares, which would lead to significant travel habits changes among the majority ofrespondents. This would result in a high number of both frequent car drivers and frequent public transit commutersthat would commute more by public transit and drive less.

Zhao, Zhan. "Understanding car pride". Thesis, University of British Columbia, 2013. http://hdl.handle.net/2429/45176.
Testo completoAbstract (sommario):
More than a tool that provides mobility, the car is also a commodity with symbolic values related to the sense of self-regard. To various degrees, people pride themselves on being car owners or users. Based on a literature review primarily of a plethora of psychological theories, this thesis proposes a framework that defines the concept of car pride, examines the process of its formation, and classifies different types of car pride. Car pride is measured using data collected from a survey in Shanghai. Although household income and location are found to be significant predictors, car pride cannot be effectively explained by individual socio-economic characteristics. Car pride and ownership are found to be interdependent. The 2SLS model finds a significant impact of ownership on pride. Conversely, car pride can influence whether someone plans to buy a car, more so for first-time car buyers. In terms of the relationship between car pride and car use, the influence of car use on pride is weak, but car pride significantly stimulates car use. The relationship between car pride and other attitudinal factors is also investigated. A positive correlation between pride and dependence indicates people with high car pride are usually more dependent on cars. Public acceptance of car ownership restriction policies can also be subject to the influence of car pride. People with high car pride, though having strong desire for cars, tend to support policies that restrict car ownership, possibly because such policies make car ownership more exclusive and special. Car pride in Shanghai is compared with Beijing to reveal regional similarities and differences of car pride. It is found although overall car pride is similar in the two cities, car pride in Beijing has much more variation. Overall, this thesis provides a systematic understanding on its psychological structure, and its role in shaping people’s behavior (in terms of car ownership and use) and attitudes (in terms of car dependence and acceptance of car ownership restriction policies). It is suggested car pride can have important implications in addressing transportation issues such as traffic congestion and rapid motorization.

Its cars are featured in several films of the 007 sagas and are seen by the public as products that display exclusivity, elegance, innovation, and style, coupled with performance and engineering. This project aims to evaluate the shares of Aston Martin Lagonda Global Holdings Plc and consequently calculate the value of the company, considering the structure and recommendations of the CFA Institute. This report is based on public information and was prepared on July 3rd, 2020, any information made available after that date will not be considered in the valuation. According to the Free Cash Flow to the Firm valuation method, the target price for 2020 is £0.84, i.e., a potential increase of 31.75% based on the share value on March 31st, 2020. To support the valuation, the Adjusted Present Value (APV) and the Residual Income (RI) were computed giving a positive recommendation of strong buy and buy respectively. Considering this information, I present a buy recommendation, however, any investor must be aware of its investor´s profile and relationship with risk. Along with this recommendation, I highlight that the company presents a high level of risk, mainly due to its recent history, the uncertainty of the ability to implement the developed plans, and the uncertainty in the market due to Brexit and Covid-19.

Testo completoAbstract (sommario):
This thesis examines the theoretical properties of different price cap schemes that have been applied in the UK and the USA. The objective is to assess the consequences for price structures and welfare of different ways of defining the regulated price index. Chapter 2 surveys the literature on regulation under asymmetric information that is related to price caps. Chapter 3 presents a general analysis of five main types of price cap when the regulated firm sets linear tariffs. The schemes are the Tariff Basket (TB) scheme, the Fixed Weights (F) scheme, the Average Revenue (AR) scheme, the Average Revenue (Lagged) scheme, and the Paasche Price Index (PPI) scheme. The TB and PPI schemes generate efficient price structures in the long run, whereas prices are inefficient under the other schemes. In Chapter 4 the consequences of allowing freedom to set different prices, relative to the case of uniform prices, are analyzed. The conditions for price freedom to be desirable are derived for the case where the price level is not regulated. When the price level is regulated it is shown that AR regulation can cause welfare to be below the level that obtains without any regulation. Chapter 5 contains an analysis of the five price caps examined in Chapter 3 for the case where the firm sets a two-part tariff. The AR and PPI schemes are dominated, and the conditions under which TB, F and ARL are optimal are established. Chapter 6 explores some issues in the regulation of nonlinear tariffs by AR and TB price caps. Chapter 7 considers some extensions of the analysis. It is shown that when quality is a choice variable, the regulator is concerned about income distribution and there is demand growth the TB scheme can be adapted and retains its desirable properties. Chapter 8 contains conclusions and suggestions for future work.

Jenkins, Cloda. "Efficiency properties of price cap regulation". Thesis, University College London (University of London), 2004. http://discovery.ucl.ac.uk/1446658/.
Testo completoAbstract (sommario):
Price cap regulation has been used to control the monopoly behaviour of utility firms in the UK since 1984. The RPI-X regime currently in operation is very different to the regulatory mechanism originally proposed, and to the theory of pure price cap regulation. We therefore argue that it is necessary to examine how the mechanism is actually designed and implemented, if we are to determine its impact on economic welfare. A detailed description of RPI-X regulation is presented here. This description is used to examine the impact of the price cap mechanism on allocative efficiency, technical efficiency and the efficient delivery of quality of service. We also examine the impact of regulation on welfare by calculating the rate of growth in productivity in the water and electricity sectors since privatisation. Our analysis of the efficiency properties of RPI-X regulation exposes flaws in the regime. There is, however, scope to change the regulatory contract and potentially increase welfare. First, the way in which the price cap is set can be altered. For example, a revised methodology can be used to share cost savings with consumers. Alternatively, the form of the contract can be changed so that more restriction, than a single cap, is placed on the firm's price choice. We consider how the proposed changes may deliver a higher level of welfare given the constraints of the existing legal and institutional framework. The limited relevance and feasibility of the proposed changes, arising from the characteristics of demand and cost functions in the regulated sectors, are also emphasised.

As the world recognizes that its growing reliance on private, fossil fuel-based vehicles is unsustainable, understanding how to avoid growth in car ownership and how to shift current users towards more efficient, environmentally-friendly, safe, and inclusive alternatives is a critical vision for meeting sustainable (transportation) development goals. Policy makers looking to shift consumer behavior away from cars need a more rigorous understanding of how different attitudes play a role in influencing car ownership and use and how this might vary by people and place. In this dissertation we provide deep insight into one of the many symbolic and affective motives behind car consumption: "car pride" or the attribution of social status and personal image to owning and using a car. Using data collected from individuals in two U.S.
cities and in 51 countries around the world, we develop and demonstrate the reliability, validity, and invariance of polytomous (12, 7-point Likert-format statements) and dichotomous (9, dichotomous statements) survey measures for car pride using confirmatory factor analysis (CFA). With these measures, we explore variations in car pride across individuals, cities, and countries using Structural Equation Modeling (SEM). Across individuals, we find that those who are younger, male, and have higher incomes generally have higher car pride. Controlling for individual characteristics, we find that car pride is influenced by context. Between U.S. cities, we find that Houston has higher car pride than New York City. Across countries, we find that less developed countries exhibit higher car pride. We also disentangle the bidirectional causal relations between car pride and car consumption using instrumental variable (IV) techniques.
We find that car pride strongly predicts car ownership, while no statistically significant relation exists in the opposite direction. Car pride additionally predicts car use, but only through its relation with car ownership (mediator). In the reverse direction, car use strongly reinforces car pride. While the directions of these relations appear almost universal across contexts, their strengths differ by country, emphasizing the importance of taking national context into account when measuring and interpreting symbolic motivations for car consumption. This dissertation builds a systematic understanding of car pride and its relations with car consumption across individuals, cities, and countries. For researchers, it serves as an example of methodological good-practice for empirical studies of attitude-behavior relations in transportation.
For policymakers, it builds awareness of how policies can target attitudinal, social, and cultural factors, such as car pride, that present additional obstacles to the adoption of more sustainable transportation alternatives at both the individual and national levels.

Testo completoAbstract (sommario):
Aim: The purpose of this study is to find new variables that can help explain the variation in the prices of apartments in the county of Stockholm. Method: By using recreated variables from an existing model created by Claussen, Jonsson and Lagerwall (2011) on behalf of Sweden’s central bank, and adding new variables obtained by the realtor Erik Olsson and the housing ad website Hemnet, the goal is to find a model that explains as much of the price variation as possible. The accuracy of the model is tested by an out-of- sample forecast. The study is based on monthly data for the years 2008 up until February 2013 and is written in cooperation with Valueguard. Findings: By combining the two data sets the adjusted coefficient of determination was 0,703, which means that 70,3% of the variation in the prices can be explained by the model.

Testo completoAbstract (sommario):
Firms have had difficulties in dealing with the risks that occur when providing fixed price contracts (FP) for both small – scale and large – scale projects to involved customers. This is general for the most companies surveying customers with the development for a product or service in the IT – industry. Research has paid minimum attention on how firms can imple-ment scientific proven agile methods to reduce the risks with FP contracts to increase profit margin. In FP contracts, the risks lie on the supplier providing the contract, where research has shown that companies have issues in determining the project scope in the planning pro-cess and how they can find certain approaches for increasing the dialogue in a buyer and seller arrangement. Therefore, firms are more comfortable in going into Time and Material (T&M) arrangements where customers pay for the time and resources spent under a project process. This study also makes investigations on how firms can make accurate estimations of the development durations that occurs when providing this contracting form and how firms can identify risks into profitable pricing engagements. The study took ground in Lund, Swe-den at a company named Sigma Connectivity which is a firm developing services and prod-ucts based on wireless communication and the phenomenon called Internet Of Things (IoT).The delimitations that were made for this study was related to the marketing mix concept which conducts of seven strategies for business management of these seven strategies the choice was made to exclude exclude sustainable aspects, physical evidence, internal market-ing related to promotion, and location factors. Internal qualitative directive and semi – struc-tured interviews were methods used for determining variables and key issue with FP contracts that was included in the survey based approach to customers. Agile methods such as Feature Driven Development (FDD) and Work Breakdown Structure (WBS) were implemented in or-der to tackle the challenges of visualising a clear project scope description with clear specifi-cation on what is included in a FP contracts in small – scale and large – scale projects.The results conducted from this study shows that integrating scientific proven methods such as FDD and WBS in a firm, will help them to divide project processes into smaller mecha-nisms, which will provide sufficient access for an increased project scope allocation forcing the involved parties in a buyer and seller arrangement to hold both internal and external re-views which will enable the possibility of making pricing approaches during the project pro-cess. Results also shows that customers find FP contracts to be the most valuable but the diffi-culties that they have felt in this arrangement is to incorporate new ideas for a project scope change during a project process. The use of the FDD framework and WBS provided results that are vital for firms going into FP arrangements where clearer project scope definitions, key role identifications, increased pricing opportunities and communication channels were founded.Keywords: Fixed price contracts (FP), project scope, Work Breakdown Structure (WBS), Feature Driven development (FDD).

Alalasundaram, Sudhersena. "Effect of child care subsidies on price and quality of care for low -income families". FIU Digital Commons, 1997. http://digitalcommons.fiu.edu/etd/1181.
Testo completoAbstract (sommario):
This dissertation examines the effect of regulations, resource and referral agencies, and subsidies on price and quality of care in child care centers. This research is based on a carefully developed conceptual framework that incorporates the factors affecting the demand and supply of child care. The first step in developing this framework is sketching out the structural equations. The structural equations help us understand the underlying behavior of individuals and firms making a decision. The exogenous variables are vector of attributes relating to family characteristics, child characteristics, regulations, subsidy, community characteristics and prices of inputs. Based on the structural equations, reduced form equations are estimated to find the effect of each of the exogenous variables on each of the endogenous variables. Reduced form equations help us answer public policy questions. The sample for this study is from the 1990 Profile of Child Care Settings (PCCS) data in which 2,089 center based programs were interviewed.
Child/Staff Ratio (Group Level): Results indicate that among subsidies, only the state subsidy per child in poverty has a significant effect on the child/staff ratio at the group level. Presence of resource and referral agencies also increase the child/staff ratio at the group level. Also when the maximum center group size regulation for 25-36 months becomes more stringent, the child/staff ratio at the group level decreases.
Child/Staff Ratio (Center Level): When the regulations for the maximum child/staff ratio for age groups 13-24 months and 37-60 months become lax, the child/staff ratio for the center increases. As the regulation for maximum group size for infants becomes stringent, the child/staff ratio decreases. An interesting finding is that as the regulations for maximum group size for age groups 13-24 months and 25-36 months become stringent, the child/staff ratio for the center increases. Another significant finding is that when a center is located in a rural area the child/staff ratio is significantly lower.
Center Weighted Average Hourly Fees: Maximum group size regulations for age groups 25-36 months and 37-60 months have a negative effect on center hourly fee. Maximum child staff regulations for age groups 13-24 months and 37-60 months have a negative effect on center hourly fee. Maximum child staff regulations for age groups 0-12 months and 25-36 months have a positive effect on center hourly fee. Findings also indicate that the center average hourly price is lower when there is a resource and referral agency present. Cost adjusted prekindergarten funds and JOBS child care subsidies have a negative effect on average hourly fee. Cost adjusted social services block grant and state subsidy per child in poverty have a positive effect on the average hourly price. A major finding of this dissertation is the interaction of subsidy and regulatory variables. Another major finding is that child/staff ratio at the group level is lower when there is an interaction between geographic location and nature of center sponsorship.

This article investigates the influence of competition on price and product quality among Austrian camping sites, a market characterized by both horizontal (spatial) and vertical product differentiation. Theoretically, the effect of competition on quality is ambiguous and depends on the degree of cost substitutability between output and quality. Estimating a system of equations shows that intense competition has a positive impact on product quality and a negative effect on prices (conditional on quality). As high quality is associated with high prices, the total effect of competition on prices is rather small.

Lenders typically learn new information about their borrowers over time but can be restricted from repricing debt in response to this information. I study a leading example of such re-pricing restrictions, the 2009 Credit CARD Act, to ask how such restrictions affect credit market efficiency. Using a near-universe of US consumer credit card account data as well as a large random sample of US consumer credit reports, I show evidence that the Act's restrictions had two competing effects: on the one hand, a decoupling between prices and default risk on existing loans over time, which engenders adverse selection through higher attrition of safe borrowers; on the other hand, lower markups on borrowers revealed to be inelastic, and hence lower price dispersion in the market overall. To quantify these two forces' net effect on market efficiency, I build a model of a competitive credit market with private information and changing borrower types over time, and I use the model to ask whether, and for whom, the Act's restrictions bring prices closer to an efficient benchmark of prices equaling marginal costs. While fully estimating the model remains a goal for future work, I here show preliminary results of how the model estimation is proceeding.

Testo completoAbstract (sommario):
Mutual funds and money managers have recently come under fire for their inability to beat market level returns since the Great Recession. With the recent trend towards passive money management through ETFs and other market-based securities, many investors have come to doubt whether above market returns are realizable in today’s economic climate. This paper examines whether business news has any predictable impact on stock price. Specifically, the paper explores the impact of analyst reports, mergers & acquisition news, legal affairs, insider buying and selling and changes to executive leadership on a stock’s excess returns. The results show that optimistic analyst ratings are correlated with positive excess returns before, during, and after the ratings are released. Furthermore, pessimistic analyst ratings are correlated with negative excess returns over the same time frame. These results provide support for a short term trading strategy that mirrors analyst opinions.

Ce mémoire étudie la relation entre les prix du pétrole et de l’énergie et le taux de change CAD/USD au moyen d’un modèle à correction d’erreur étroitement lié à l’équation du taux de change de la Banque du Canada. Une rupture structurelle se produit dans la relation entre les prix du pétrole et de l’énergie et le taux de change CAD/USD lorsque ce dernier est à parité. Par conséquent, un modèle à correction d’erreur est utilisé pour estimer le taux de change CAD/USD en intégrant l’effet de la parité par rapport à la non-parité dans l’équation de prévision. En outre, la sensibilité de l’équation du taux de change varie selon la présence ou l’absence de parité. Plus précisément, lorsque la parité est atteinte, le taux de change CAD/USD a moins tendance à répondre aux changements de prix du pétrole et de l’énergie.This thesis studies the relationship between oil and energy prices with the CAD/USD exchange rate using an error correction model closely linked with the Bank of Canada’s exchange rate equation. A structural break occurs in the relationship between oil and energy prices and the CAD/USD exchange rate when this latter is at parity. Accordingly, an error correction model is employed to estimate the CAD/USD exchange rate by incorporating the effect of parity versus non-parity in the forecasting equation. Moreover, the sensitivity of the exchange rate equation shifts in the presence of parity versus the absence of parity. More precisely, when parity occurs, the CAD/USD exchange rate responds less to changes in oil and energy prices.

Este trabalho busca identificar, discutir e propor um método capaz de avaliar e comparar eficiência na gestão e operação da infraestrutura concedida. Com foco na busca por um método que permita auxiliar a regulação price-cap, propõe uma forma de cálculo para o fator “x” dos reajustes tarifários, fator vinculado ao desempenho das concessionárias de serviços públicos. Serão identificados os principais métodos matemáticos utilizados em estudos acadêmicos e na prática regulatória, para avaliação e comparação de eficiência, bem como apresentadas suas principais vantagens e desvantagens. Apresentar-se-á uma discussão sobre quais modelos regulatórios permitem o uso do benchmarking como ferramenta auxiliar na decisão e uma proposta de uso para o cálculo do fator “x”, utilizando os métodos da Análise Estocástica de Fronteira (SFA) e a Análise Envoltória de Dados (DEA). Ao final, a aplicação do modelo proposto, em estudo de caso com concessionárias de rodovias federais brasileiras, permitirá avaliar a aplicabilidade da ferramenta. O objetivo do benchmarking como ferramenta regulatória é incentivar a inovação e promover, artificialmente, a concorrência entre empresas em mercados naturalmente monopolistas, como o da infraestrutura de transportes.This work tries to identify, discuss and propose a method to evaluate and compare management and operational efficiency in infrastructure concessions. Proposing a method to calculate the “x” factor from the price-cap regulation, this paper wants to promote the discussion about the performance of the public services concessionaries. Through the text we identify the two most used mathematics methods, in academic studies and practical regulation, to evaluate and compare performance. We discuss it advantages and disadvantages, proposing a combination of the two methods to make a benchmarking approach. After this, we use the Stochastic Frontier Analysis (SFA) and the Data Envelopment Analysis (DEA) to make a case study about the Brazilian federal highways concessionaries. For it we use our proposed model to find the “x” factor, attempt to propose the benchmarking like a tool to promote innovation and to insert, artificially, competition, between companies, in monopolistic markets like the transport infrastructure.

Testo completoAbstract (sommario):
This paper examines whether the phenomena of price drift around quarterly earnings re-leases exist among firms listed on the large cap. list at the Stockholm Stock Exchange for a time period ranging from the first quarter of 2003 to the second quarter of 2006. It fur-thermore examines the ability of the variables forecast error, relative to analyst’s estimates, and firms’ size to explain the variation in price drift among firms.
A sample of some 30 firms were drawn in the first three quarters of each year between 2003 and 2005, for the year of 2006 only the fist two quarters were included in the study. For each quarter all firms were classified into three different portfolios on the basis of earnings deviations relative to mean analyst’s estimates (forecast error). The returns for each firm in all portfolios were investigated during 20 days post- and pre quarterly earnings release date, resulting in an event window totaling 41 days. In order to clear out effects from general market movements the Capital Asset Pricing Model, CAPM, was used in which betas were estimated for all firms each quarter.
The findings from this study indicate that price drift, measured by cumulative abnormal re-turn, occur for firms with both negative forecast error as well as positive. For firms with positive error, statistically significant positive price drift was found for both the pre- and post period. As for the firms with earnings below analyst’s mean estimates, negative prean-nouncement drift was statistically supported.
The ability of firms size and forecast error to explain the variation in price drift on a stock level was very weak, R2 measures of below 5% was reported. However, forecast error was a strongly significant independent variable in the context of the regressions run for both pre- and post-announcement drift. The firms below the lower market cap. quartile in the sample show, on average, lower pre-announcement drift than the firms belonging in the largest quartile.
Concerning market efficiency among the large cap. firms the price drift found is an indica-tion of market inefficiency both it terms of the semi strong and the strong form. However, care should be taken before generalizing the results from this study but. Possible misspeci-fication of the equilibrium return model will skew the price drift measurement. Moreover, speculation is not explicitly controlled for in this test. Finally, this study is done within a li-mited time span; hence generalization over time is not possible

Testo completoAbstract (sommario):
Value shares are notorious for remaining stagnant for extended periods of time, forcing value investors to remain locked in their investments often for excessive periods. This research study applied the price acceleration momentum indicator of Bird and Casavecchia (2007) on a value portfolio with the objective of improving the timing of value share acquisitions.A time series study was conducted, taking into account the top 160 JSE shares over the period 1 January 1985 to 31 August 2012. A price acceleration momentum indicator was applied to enhance a value portfolio formed on the basis of book-tomarket ratio, dividend yield and EBITDA/EV. Cumulative average abnormal returns (CAAR) were used to compare portfolio results statistically.A substantial contribution is made to the literature by proving that a value-only portfolio can be significantly enhanced by the combination of price acceleration momentum. Results indicated an increase in CAAR from 199.83% to 321.29%. Risk-adjusted returns (Sharpe ratio) were also improved without the detriment of increased share price volatility (standard deviation). This research study further contributes to the literature by proving that a price acceleration momentum indicator adds no additional value over a value portfolio combined with ordinary price momentum.Dissertation (MBA)--University of Pretoria, 2012.

Testo completoAbstract (sommario):
The study explores price transparency in the healthcare system. With the increase in healthcare spending resulting in the advent of high deductible plans, consumers have been exposed to high healthcare cost. Despite being burdened with outrageous and extravagant bills, studies have shown that the consumers are not using price transparency tools to their benefit.
The literature review reveals that the major stakeholders in the healthcare industry have never been studied together to understand the research question on ‘Why is there lack of price transparency in the healthcare system?’ moreover, there is no theory to explains this phenomenon.
This study undertakes a 360-degree, exhaustive view of all the major stakeholders of the healthcare industry in aims to understand the reasons behind the lack of price transparency in the healthcare system and what is holding the industry back.
The study followed a grounded theory methodology approach, utilizing the data from 78 semi-structured interviews. The 78 professionals and executives representing the major stakeholders in the healthcare industry contributed to providing information to uncover the key factors for an opaque healthcare industry.
Eighty-five hours of interviews resulted in 1,686 transcribed pages that provided insights and discernment to understanding the complexities and intricacies in the healthcare industry that prevent it from becoming fully transparent. The results provide the richness of data for an emergent theory that explains the actions taken by major stakeholders to reduce healthcare spending based on their intrinsic interests and their perceptions of complexities of the healthcare industry.
The study presents practical implications on how a complex industry is slow to evolve and that a change is not possible unless it is deconstructed layer by layer to recognize the root cause. The change has to start from the core by simplifying the complexities that are created over time by the stakeholders who have always looked to optimize their motivations and have had no incentives to make the industry efficient.

Testo completoAbstract (sommario):
Main goal of this Master's thesis was to evaluate how price reductions influence consumers' likelihood to purchase FMCG products in connection to brand loyalty. Czech customers are characterized by high sensitivity to sales promotions. This thesis is focused on analysis of price discounts of shampoos in the Czech Republic. Leaflets of main retailers selling drugstore products were researched in order to describe the frequency and discount depth of shampoos. Customers' behaviour while buying shampoos and their attitude towards price discounts of shampoos were examined through a questionnaire. Main hypotheses that shampoos are discounted very frequently and of significant depth were confirmed. To conclude, customers' likelihood to buy shampoos increases heavily with discounted prices and some of the customers even believe that it is not worth buying shampoos for full prices.

Testo completoAbstract (sommario):
In 1991, the Federal Communications Commission began regulating the tariffed rates of the nation's largest local exchange carriers under a new regulatory scheme: price-cap regulation. Price caps were intended to "remedy" the ills of traditional rate-of-return regulation. They were to provide incentive for the telephone companies to adopt innovative technology, cost-cutting measures and provide telephone services more efficiently. To test the effectiveness of this incentive, this study examined productivity of the regional Bell operating companies (RBOCs) under both rate-of-return regulation and price-cap regulation. A total factor productivity model was developed and productivity gains were calculated under both regulatory regimes. The assumption of total factor productivity was then relaxed and value-added productivity and labor productivity measures were also examined. The point estimates of productivity gains indicate that price caps have led to greater productivity gains. Although productivity gains varied greatly across individual RBOCs, use of total RBOC data indicated that average productivity gains improved 1.3 percent under price caps using the TFP model. Similar improvements under price caps were estimated using the value-added (1.1 percent) and labor productivity measurements (1.3 percent). However, because of the variability of the annual estimates, none of the productivity improvements are statistically significant. In conclusion, calculations of RBOC productivity gains suggest that price caps have led to more efficient use of inputs--labor; materials, rents and services; and capital--in the production of telephone company output. Yet, the statistical evidence is not strong enough to unequivocally support the assertion that price cap regulation has led to great productivity gains.Master of Arts

Testo completoAbstract (sommario):
Retailing is the considerable element of today economy. This sector was rapidly developing during past years. It was easy to make consumers spend their money because they wanted to spend money. Today consumers are no longer eager to spend as much as before. Therefore retail companies should find new ways to motivate customers to expend. The aim of this research is to define to which extent retailers suffered from economic downturn and to find out which marketing tools they implemented in order to adapt to new market conditions. In order to investigate the variety of possible scenarios, two countries were taken into consideration. Sweden as one of the most stable economies in the world and Russia as country with promising perspectives but unpredictable and risky environment. The goal of taking two countries for the survey was identifying common and diverse traits of changed retailing conditions and necessary measures to follow it. Qualitative method was chosen for current dissertation embodied by case study analysis of leading retail companies in both countries. Primary data from conducted interviews and secondary data from annual reports and statistical authorities were used for analysis. The findings showed that Russian retail was stricken by economic downturn much more than Swedish. Apart from it, customer’s behavior in Sweden did not change significantly as long as Russian consumers changed their store format preferences in favor of discounters. Despite difference revealed in this issues the common characteristics of successful post-recession marketing strategy were discovered. Low price is now the key element of successful retailer. Other elements of marketing strategies play only supportive role in struggle for consumer’s wallets.

Price of the second-hand car depends on many factors, such as age, conditions of body and interior, mileage, type, manufacturer and many others. This research examines determinants of second-hand vehicle price using the example of Taiwan auctions. The research focuses on used passenger cars which were produced in Taiwan and whose final price does not exceed one million New Taiwan Dollars. Trucks, imported cars and luxury vehicles were excluded from the research. The study uses data from used cars auction website which included observations of successful transactions in 2014. The log-linear multiple regression model is applied to evaluate this data. According to the results, polynomial log-linear multiple regression model is more suitable for this research and produces better results. As the result shows, all chosen variables are statistically significant at 1% confidence interval (p-value<0.01) and all coefficient signs are as expected. Only one variable LOG(MILEAGE) is not statistically significant.

Project Work presented as the partial requirement for obtaining a Master's degree in Data Science and Advanced Analytics, specialization in Data ScienceModern data sources routinely contain information both in unstructured and structured forms, combining text with the usual numerical and categorical data. For instance, in websites dedicated for selling and buying cars the listings typically include a textual description of the car. Others also include a detailed list of numerical or categorical attributes, such as the total number of kilometers the car has, or it´s model. In this work project we apply text mining techniques to create predictors for car price regression from unstructured data, the textual description in car listings. Two different types of predictors were studied, the tf-idf features obtained from the n-gram count matrix, or the singular vectors derived from the decomposition of the tf-idf matrix. In this work we also examine the performance of reducing the vocabulary dimension by applying stemming, lemmatization or not applying either of those. We also compare the effects of creating the initial n-gram count matrix with only unigrams, unigrams and bigrams or only bigrams. Our regression experiment shows that Support Vector Regression performs best at car price prediction using text data as predictors with R2 = 0.77, MSE = 0.19 and MAE = 0.32. These results can be seen as respectable given the complex nature of the task.

The purpose of this research is an analysis of the influences of the West Texas crude prices ( WTI ) to the stock prices of the Taiwan automobile and bike industries ( Yulon, China mobile, Hotai, Giant and Merida ). The prices of crude keep raising in recent years. There are three times of crude crises, the war between Israel and Egypt in 1973, the war between Iraq and Iran in 1980 and Gulf war in 1990. Beside these, WTI raised more than 100 in 2008 and 2011. The prices of crude changed dramatically during these periods. We tried to discuss will the fluctuations of the WTI change the decisions of the Taiwan investors. If WTI raises, the investors of automobile will take the policy of “sell out instead buy in” and the investors of bike will take the policy of “ buy in instead sell out “ We used basic descriptive analysis, unit root analysis, Granger causality test, correlation analysis and multiple regression analysis to get empirical analysis. The results show there is no relation between WTI and Yulon , but there are significant positive relations between WTI and China and Hotai motor co. This means the automobile stock prices would not be suppressed by the inflation of the crude. There are other factors influence the performance of automobile stocks, maybe the economic factors contribute the customers. There are significant positive relations between WTI and Giant and Merida. This reflects WTI raises will stimulate the investors prefer bike more.
