In order to analyse the effect of exchange rate uncertainty, we apply an empirical gravity equation to two sets of US bilateral trade data: fresh fruit over the period 1976--1999 for a panel of 26 countries; and fresh vegetables over the period 1976--2006 for a panel of nine countries. Based on...

Habitual behaviour in consumer demand analysis is generally portrayed via some form of a lagged dependent variable model. The purpose of this paper is to explore the implications for habit behaviour of time aggregation. This is done by specifying both habit and seasonal components in demand...

This manuscript focuses on the productivity-industrial concentration relationship in the US manufacturing industries, while accounting for external and internal sources of knowledge. It is found that there is a critical level of industrial concentration beyond which its relationship with...

What has been ignored in much of the existing studies of oligopoly power is that market behaviour need not be static in nature, and oligopoly power in agriculture need not be present in every month of the year. In a market which is characterized by seasonality and supplied by different sources...

Empirical applications of testing oligopoly power in different industries are based on the 'new empirical industrial organization' (NEIO) approach. Parallel to this approach, theoretical and empirical applications to testing oligopoly power in international trade have also emerged. A shortcoming...
