This paper develops a Hotelling location model in which two radio stations choose combinations of local and international content to play, given consumers with preferences distributed over those combinations. Station revenue derives from sales of advertising time, the demand for which depends...

This note considers Hotelling’s (1929) model of locational choices by two firms and subsequent price competition in a setting where atomistic consumers locate first. It is shown that any equilibrium in pure strategies involves either one or two mass points with all surplus captured either by...

The analysis of global population forecasts of the past 30 years by the US National Academy of Sciences confirms that errors have been considerable and that population forecasts have generally been upward-biased. Recent stochastic population projections also yield wide error bounds. We discuss...

Since the 1970s Britain has gone from being a country of net emigration to one of net immigration, with a trend increase in immigration of more than 100,000 per year. This paper represents the first attempt to model the variations in net migration for British and for foreign citizens, across...

This paper considers the application of ‘cultural quotas’ to radio broadcasting: a requirement that a minimum percentage of broadcast content be of local origin. Using a Hotelling location model derived in Richardson (2004) we show that, while the laissez-faire solution involves less than...

Pressure from negotiators on agricultural tariff reform in the Doha Round is favouring commitments to reduce “average” tariffs over a range of commodities. This stems from the perceived need for “flexibility” in protection levels, particularly for some highly protected product groups...

In this paper, we consider the non-parametric, kernel estimate of the density, f(x), for data drawn from stratified samples. Much of the data used by social scientists is gathered in some type of complex survey violating the usual assumptions of independently and identically distributed data....

Receipt of unemployment insurance by immigrant men and social assistance by immigrant families are analysed using thirteen surveys from Canada. Estimates from a cohort fixed effects model are found to be sensitive to the choice of survey years. This is due to the mis-specification of the fixed...

In strictly competitive games, equilibrium mixed strategies are invariant to changes in the ultimate prizes. Dixit & Skeath (1999) argue that this seems counter-intuitive. We show that this invariance is robust to dropping the independence axiom, but is removed if we drop the reduction axiom.

This paper extends analysis of the GATT Uruguay Round qualifiying the impact of international patent harmonization as implied by the TRIPs agreement.
