This contribution studies the application of heteroskedasticity robust estimation of Vector-Autoregressive (VAR) models. VAR models have become one of the most applied models for the analysis of multivariate time series. Econometric standard software usually provides parameter estimators that...

I/O models have been widely used to assess the impacts of many changes in an economy. An I/O model is also an important tool to make forecasts and the results from an I/O model are very helpful in many policy-making processes. Many scientific findings in economics have to give credit to the I/O...

This paper extends previous studies in modeling and estimating energy demand functions for both gasoline and kerosene petroleum products for Nigeria from 1977 to 2008. In contrast to earlier studies on Nigeria and other developing countries, this study specifically tests for the possibility of...

The hypothesis that devaluating and depreciating the exchange rate in developing economies will lead to fast growth and economic development has drawn some controversies and debates during the past 20 years in the area of development economics. Mainly, due to the delayed results in some...

In this study, we used the PSTR (panel smooth transition regression) model to investigate the nonlinear relationship between beta (systematic risk) and returns (world market excess returns) for net oil export and net oil import groups. We set the volatility of world market excess return as the...

Cross-country estimations of the Environmental Kuznets Curve (EKC) to empirically analyze the relationship between income and pollution have generally assumed a common structure for all countries. Since this latter feature is not supported by economic theory, this paper uses the Random...

Das Erneuerbare-Energien-Gesetz (EEG) hat sich als wirkungsvolles Instrument zur Förderung von Strom aus erneuerbaren Energien erwiesen und ist in seiner Grundstruktur von einer großen Anzahl anderer Länder übernommen worden. Beim EEG besteht die Förderung insbesondere aus einer...

This work analyzes the use of the train by the Galician companies when they do business transactions with northern Portuguese operators. The residual usage of this infrastructure (0.01 of all the transactions) is proved opposite the masive use of the truck; factors that explain the choice and...

This paper proposes another realistic application of the economic order quantity EOQ model. Researchers have studied EOQ models that assume the received lot contains items that are perfect and imperfect. All models in the literature assume that the received lot goes through a 100% inspection to...

This paper evaluates the effect of an anti-poverty program, Chile Solidario, during its first two years of operation. We find that the program tends to increases significantly their take-up of cash assistance programs and of social programs for housing and employment, and to improve education...
