Abstract:
Purpose This paper aims to first investigate how unit pricing affects consumers’ grocery purchase decisions and perceptions of the shopping task’s information load. The second goal is to test how time pressure enhances the behavioural and perceptual effects of displaying unit prices.

In Study 1, participants indicated their choices and perceptions in an inter-brand shopping scenario where prepackaged products have conflicting positions on retail price and unit price.

Abstract:
Supermarkets often list sale prices in terms of how many items for how much. For example, recently I saw that Snickers bars were advertised at 8 bars for $3 and cans of SpaghettiOs were selling at 4 for $5. Are those good prices? How much is it if I buy only one bar or can? The price of one bar or one can is called the unit price. One way to think about unit price in the setting of these sale prices is to think about fraction-to-percent equivalents.

The effects of the U.S. dollar exchange rate versus the Mexican peso are evaluated for four traded nonfarm-produced inputs (fertilizer, chemicals, farm machinery, and feed) in the U.S. Unit root tests suggest that the exchange rate and the four input price ratios support the presence of unit roots with a trend model but the presence unit roots can be rejected in the first difference model. This result is consistent with a fixed price/flex price conceptual framework, with industrial prices more likely to be unresponsive to the exchange rate than farm commodity prices.

Therefore, stationarity tests at seasonal frequencies also need to be applied.

Abstract Objectives Affordability and availability of medicinal products depend on governmental policies, healthcare budgets and pricing. Pharmaceutical price regulation can improve the accessibility and affordability of essential medicinal products. In Europe, medicinal product prices are assigned individually by each country. The study aimed to compare prices of medicinal products indicated for cardiovascular (n = 18) and respiratory disease (n = 9) available for retail in community pharmacies in five European countries.

Abstract:
Abstract The unit values of internationally traded goods are heavily influenced by quality. We model this in an extended monopolistic competition framework where, in addition to choosing price, firms simultaneously choose quality subject to nonhomothetic demand. We estimate quality and quality-adjusted price indexes for 185 countries over 1984–2011. Our estimates are less sensitive to assumptions about the extensive margin of firms than are purely “demand-side” estimates. We find that quality-adjusted prices vary much less across countries than do unit values and, surprisingly, the quality-adj

Design/methodology/approach Exploiting the unit root feature, the cointegrated vector autoregressive model solves the problem of misspecification. Subsequently, variables are modelled for a long-run equilibrium with included deterministic variables. Findings The empirical results confirmed that overnight stays for foreign tourists were positively associated with the prices of short-stay accommodation. Research limitations/implications The

This study examines the explosive behaviors of house prices in Seoul and its metropolitan areas during 2008Q1~2023Q1. In order for the relationship between house prices and cash flows to reflect better the Korean housing market, this study adopts price-to-income ratio, real transaction-based house prices and personal income. Based on the generalized supremum ADF (GSADF) test, our empirical findings show that housing bubbles are identified in all three markets. According to the starting period, duration periods, and magnitude and prominent peaks among GSADF statistics, the bubbles in Seoul hous

This paper uses panel data from 116 prefecture-level cities in China from 2003 to 2019 to study the impact of price and climate factors on soybean planting area and yield per unit area in China. We adopt the panel instrumental variable method to control the endogeneity of the price in the regression and allow possible spatial autocorrelation errors. According to the research results, price is the primary factor affecting soybean production. For every 1% increase in soybean prices, the soybean planting area increases by 1.650%, and the per unit yield decreases by 0.898%. As for fertilizer price

Abstract:
In the U.S., multihospital systems (MHSs) charge significantly higher prices for hospital services than stand-alone hospitals. Rivalry restraint theory suggests that MHS with multimarket contact (MMC) can tacitly collude and mutually forebear from price competition to keep their prices above competitive levels. We posit that the success of such MMC-induced rivalry restraints (the truce) is affected by two conflicting roles of IT at the corporate level and market unit levels, respectively. The corporate parent seeks to standardize IT applications enterprise-wide to coordinate market units as a

Abstract Property prices vary on different local real estate markets. Even considering only the largest cities, great disproportions between average unit prices can easily be observed. This problem involves all segments of the real estate market, yet, because of the social &amp; economic importance of housing properties, it takes on special importance on the apartment market. In Warsaw - the capital of Poland and the largest Polish city - prices exceed PLN 10,000 per 1m2 in the best locations and the average price at the end of 2016 in the entire city came to over PLN 7,500 per 1m2.

Customers are highly sensitive to the prices of the products. In such situation, adjustment of unit selling price is needed to accelerate inventory depletion rate and for determining order quantity for the sales season. In this paper, we focus on the issue by jointly determining optimal unit selling prices and optimal lot size over the sales season.

Finnish occupational health services provide an opportunity to study empirically competition, ownership and payment systems and the performance of providers. In these markets employers (purchasers) choose the provider and prices are market determined. The price regulation of public providers was abolished in 1995.

The recent increase in Chinese house prices has led to concerns that China is vulnerable to asset price shocks. In this paper, we apply recently developed recursive unit root tests to spot the beginning and the end of potential speculative bubbles in Chinese house price cycles. Overall, we find that except for 2009–10 actual house prices are not significantly disconnected from fundamentals. Thus, the evidence for speculative house price bubbles in China is in general weak.
