Résumé :

Abstract We evaluate the forecasting performance of four competing models for short-term macroeconomic forecasting: the traditional VAR, small scale Bayesian VAR, Factor Augmented VAR and Bayesian Factor Augmented VAR models. Using Armenian quarterly actual macroeconomic time series from 1996Q1 – 2014Q4, we estimate parameters of four competing models. Based on the out-of-sample recursive forecast evaluations and using root mean squared error (RMSE) criterion we conclude that small scale Bayesian VAR and Bayesian Factor Augmented VAR models are more suitable for short-term forecasting than tra

Résumé :

Small-sample properties of bootstrap cointegration rank tests for unrestricted panel VAR process are considered when long-run cross-sectional dependencies occur. It is shown that the bootstrap cointegration rank tests for the panel VAR model based on levels canonical correlation analysis are oversized, whereas the bootstrap cointegration rank tests based on maximum likelihood framework are undersized. Moreover, the former tests are in general outperformed by the latter in terms of performance. The results of the investigation indicate that the ML-based bootstrap cointegration rank tests perfor

Résumé :

In this paper the theory on the estimation of vector autoregressive (VAR) models for I(2) processes is extended to the case of long VAR approximation of more general processes. Hereby the order of the autoregression is allowed to tend to infinity at a certain rate depending on the sample size. We deal with unrestricted OLS estimators (in the model formulated in levels as well as in vector error correction form) as well as with two stage estimation (2SI2) in the vector error correction model (VECM) formulation. Our main results are analogous to the I(1) case: We show that the long VAR approxima

Résumé :

This paper examines whether forecasting CPI components improves CPI forecast. We exploit quarterly data for Poland, disaggregated into 12 components. We follow methodology used in previous studies for Euro Area (Hubrich, 2005; Reijer and Vlaar, 2006). AR, MA, TAR and unrestricted VAR models are estimated using recursive sample and aggregated into CPI. Using out-of-sample forecasts, these models are evaluated and compared to the benchmark -- equivalents for aggregate CPI. The evidence is mixed. VAR component-forecast outperform benchmark. Contrary to VAR, for AR and TAR models we do not find su

Résumé :

We prove that local projections (LPs) and Vector Autoregressions (VARs) estimate the same impulse responses. This nonparametric result only requires unrestricted lag structures. We discuss several implications: (i) LP and VAR estimators are not conceptually separate procedures; instead, they are simply two dimension reduction techniques with common estimand but different finite‐sample properties. (ii) VAR‐based structural identification—including short‐run, long‐run, or sign restrictions—can equivalently be performed using LPs, and vice versa.

Résumé :

In this paper we investigate the impact of corruption on economic growth in Portugal over the period 1980-2018. The empirical approach makes use of a VAR model inspired by the standard Cobb-Douglas aggregate production function. The VAR model includes the capital stock, hours worked, total factor productivity and the corruption perceptions index (CPI) of Transparency International. The CPI combines several sources of information on the level of corruption in each country. The scale of this index goes from 0, the highest level of corruption, to 10, the lowest level.

This study was aimed at investigating the effects of energy prices on inflation in South Africa. This was achieved by means of econometric analysis and annual time series data spanning from 1994 to 2020. The findings revealed that electricity tariffs and petrol prices exhibit a positive effect on inflation in South Africa. On the contrary, interest rates and the exchange rate as control variables were found to have a negative effect on the inflation rate.

In “Modeling Stock Prices without Knowing How to Induce Stationarity” (1994, Econometric Theory 10, 701–719), we used posterior-odds calculations to evaluate restrictions imposed by a present-value model of stock prices across the equations of a VAR representation of stock prices and dividends. The results we reported are tainted by the omission of two factors: the Jacobians induced by the mapping of our priors over VAR parameters β into the restricted sample spaces relevant under hypotheses H2-H4 (hence, tainting our calculations of p(Hi|y,X) in (22) for i = 2–4), and an integrating constant

Résumé :

Electricity price forecasting has been a topic of significant interest since the deregulation of electricity markets worldwide. The New Zealand electricity market is run primarily on renewable fuels, and so weather metrics have a significant impact on electricity price and volatility. In this paper, we employ a mixed-frequency vector autoregression (MF-VAR) framework where we propose a VAR specification to the reverse unrestricted mixed-data sampling (RU-MIDAS) model, called RU-MIDAS-VAR, to provide point forecasts of half-hourly electricity prices using several weather variables and electrici

<p>Over the recent decades, natural sources of energy have become an interesting topic to investigate for researchers. Sources of energy play a crucial role in all industrial segments such as export revenue, exchange rate and stock market. One of the major sources is natural gas which its price affects many countries’ economy. This paper investigates the effect of natural gas price on the three leading natural gas exporting countries’ stock market: Russia, Norway and Qatar. This paper employs monthly data observations including natural gas price and stock exchange market index on Russia,

The provision of public goods and services to citizens is a significant responsibility of the government. The products include schools, hospitals, roads, and other infrastructure. This investment is essential to stimulate economic growth, create job opportunities, and improve living standards. The effect of development spending on economic growth has been shown in a significant amount of existing literature. However, there are still various opinions on the impact level of development spending on economic growth. Therefore, the goal of our research is to investigate the link between Malaysia's

The tendency of depletion of non-renewable resources and the environment's continuous degradation have been considered in the last centuries acceptable as side effects for achieving the economic growth and satisfying the human needs in the conditions of demographic growth following an upward trend. An adequate response to all these challenges is related to increasing the share of green GDP in total GDP, to green procurement and to the large-scale promotion of circular economy. At EU level, there are appropriate legislation and programs and packages aimed at implementing green procurement and t

Résumé :

In Myanmar, rice is an invaluable commodity both as a staple food and a source of high foreign exchange earnings through export. The country's agricultural economy has been transitioning from a planned economy to a market system since the late 1980s; however, the government has yet to engage in full-scale rice export deregulation. Therefore, Myanmar's rice marketing system works within the boundaries and limitations of a halfway-liberalized economy, inevitably eliciting questions about its performance.

Résumé :

The immunopathogenesis of dengue haemorrhagic fever and dengue shock syndrome is thought to be mediated by a variety of host factors. Enhancing antibodies are one of the key regulating molecules. These antibodies, via antibody-dependent enhancement (ADE) of infection, are able to facilitate dengue virus (DENV) growth in Fc-bearing host cells. The mechanism of ADE-enhanced DENV production is believed to be mediated through increasing the infected-cell mass. In the present work, the effect of ADE infection was explored further, focusing on the post-entry events of ADE infection. It was hypothesi

Recent advances in media capture and processing technologies have enabled new forms of true 3-D media content that increase the degree of user immersion. The demand for more engaging forms of entertainment means that content distributors and broadcasters need to fine-tune their delivery mechanisms over the Internet as well as develop new models for quantifying and predicting user experience of these new forms of content. In the work described in this paper, we undertake one of the first studies into the quality of experience (QoE) of real-time 3-D media content streamed to virtual reality (VR)

Sir, A new strain of coronavirus first detected in Nigeria has made its way into the UK, with 32 cases reported. Eminent experts have warned the variant may prove resistant to all types of the vaccines. Coronavirus has undergone yet another mutation and this one has made its way on to UK soil from Nigeria. There are growing fears that the variant will evade vaccine antibodies after it was revealed it contains the 484K mutation to the spike protein. Last month, a Nigerian scientist suggested the variant may cause more severe signs and symptoms [1–3]. It has been affirmed that the variants disco

Background: Although MYD88 L265P is highly frequent in WM, by itself is insufficient to explain disease progression since most cases with IgM MGUS also have mutated MYD88. In fact, the percentage of MYD88 L265P in CD19+ cells isolated from WM patients is typically &lt;100%, which questions if this mutation initiates the formation of B-cell clones. Furthermore, a few WM patients have detectable MYD88 L265P in total bone marrow (BM) cells and not in CD19+ selected B cells, raising the possibility that other hematopoietic cells carry the MYD88 mutation. However, no one has investigated if the
