Die Zukunft der deutschen Braunkohle in einer zunehmend von erneuerbaren Energieträgern geprägten Stromwirtschaft wird derzeit kontrovers diskutiert. An allen drei Braunkohlestandorten (Rheinisches, Mitteldeutsches und Lausitzer Revier) gibt es Pläne zum Bau neuer Braunkohlekraftwerke sowie...

COVID-19 poses an unprecedented threat to components of global business cycles including stock markets, industrial production and employment. This study investigated its impact on stock markets of 24 oil producing COVID-19-hit economies in North America, South America, Europe, Asia, Oceania and...

As in many African countries, crude oil importation is a major drain on the economy of Ghana. We estimate short-run and long-run import demand models for crude oil using data over the period 1980-2012. Results show that demand for crude oil is price inelastic in the short-run but elastic in the...

In this study, we report on the current state of the international market for crude oil. The market data we analyzed indicate that competition has intensified as a result of the now firmly-established shale oil extraction industry in the U.S. Model-based simulations also show that supply-side...

In this study, the price and income elasticities of Turkey's imported crude oil demand are analysed. In this context, annual time series data covering the period 1970-2018 are preferred for imported crude oil, real price for crude oil and real GDP. As known, Turkey is an energy dependent country...

This paper develops an innovation model where firms choose which research paths to follow. Contrary to most of the literature which focuses only on the level of investment in innovation, this model captures both the variety of research paths undertaken and the amount of duplication of research....

The paper unveils the market structure of container shipping, which suffers by many interpretations. Existing models regress between contestability, duopoly, monopolistic competition and game theory. This paper proposes an oligopoly model with two groups of companies: oligopolists and...

We develop a dynamic entry model of multi-store oligopoly with heterogeneous markets, and estimate it using data on hamburger chains in Canada (1970–2005). Because more lucrative markets attract more entry, firms appear to favor the pres- ence of more rivals. Thus unobserved heterogeneity...
