The increasing use of food commodities for biofuel production has substantial impact on prices and quantities of these and other food commodities. It is therefore likely that this trend also intensifies the competition for arable land. However, evidence for this hypothesis is generated by...

Claims for removing fossil fuel subsidies in the Global South are based on climate and equity concerns, but they can be at odds with improving access to Liquefied Petroleum Gas (LPG) as a clean cooking fuel. We examine the case of urban Senegal where LPG usage rates were among the highest in...

We combine two extensions of the differentiated duopoly model of Dixit (1979), namely Caminal and Vives (1996) and Brander and Spencer (2015a,b), to analyze the effect of consumer learning on firms' incentives to differentiate their products in models of Cournot and Bertrand competition....

It is a very well-known result that in terms of evolutionary stability the long-run outcome of a Cournot oligopoly market with finitely many firms approaches the perfectly competitive Walrasian market outcome (Vega-Redondo, 1997). However, in this paper we show that an asymmetric structure in...

This paper reinvestigates the influence of oil price uncertainty on real economic activity in the U.S. using a four-variable VAR, GARCH-in-mean, asymmetric BEKK model. In contrast to previous studies in this area, the analysis focuses on business cycle fluctuations and we control for global...

Recent developments in the literature on market structure have allowed the generation of a few key testable predictions from the theory of strategic behaviour. The seminal model considers one simple but general relationship, that between market structure and market size, focusing on the...
