It is well-known that observed data on prices and quantities of a set of goods is consistent with rational choice if the data satisfy revealed preference. In this paper, we derive estimators for demand and substitution elasticities at the observed data points for datasets satisfying the Strong...

This paper adopts panel data methodologies to investigate the impact of trade liberalisation on export growth and import growth across 28 Sub-Saharan African countries from 1981 to 2010. We find that trade liberalisation increases the growth of exports, however, imports grow faster by...

We analyze horizontal mergers in vertically related industries. In a successive Cournot oligopoly model, we first compare the profitability of mergers in the upstream and in the downstream sectors. We characterize conditions on the concavities of the input supply function and the final demand...
