In this paper we empirically analyse two counterfactual situations facing an anti-trust authority following the merger of two of the largest international cigarette companies. First we estimate a nested logit model of demand for cigarettes. The implied elasticity of demand for smoking and...

The static differentiated product demand model when applied to products with rapid product turnover and declining prices, yields implausible results. One response is to explicitly model the inter-temporal choices of consumers but computational demands require restrictive assumptions on consumer...

Despite the enormous growth in Islamic banking over the last thirty years, most studies, using DEA/stochastic frontier analysis, have found Islamic banks are either as productive or less productive than conventional banks. We take advantage of recent improvements in the direct estimation of...

With almost 15 years passing since their introduction, quantitative evaluations of Poverty Reduction Strategy Papers (PRSPs) have been surprisingly sparse. This paper examines whether a PRSP impacts on poverty reduction and well-being and whether PRSP alignment to development paradigms impacts...

Casual empiricism suggests higher quality is associated with greater variety. However, recent theoretical and empirical research has either not considered this link, or has been unable to establish unambiguous predictions about the relationship between quality and variety. In this paper we...

In this paper we empirically analyse two counterfactual situations facing an antitrust authority following the merger of two of the largest international cigarette companies. First we estimate a random coeffi cients model of the demand for cigarettes. The implied elasticity of demand for smoking...
