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...

A critique is advanced of the contention of Obstfeld and Rogoff (1983) that in a fiat money regime, 'speculative hyperinflations can be excluded only through severe restrictions' on preferences. It is maintained here, in contrast, that no more than the infinity of the marginal utility of real...

This paper examines whether the dismantling of apartheid has resulted in the improvement in the standard of living for the vast majority of South Africans. The study is based on a panel data set from the Kwazulu-Natal province. Despite the best efforts of the interview team, the attrition rate...

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...

Using a general three sector growth model, this paper derives general conditions for positive growth in the economy along a balanced growth path under the alternative assumptions of a static population and a growing population. The framework is general enough to replicate endogenous and...

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.

Using over half a century of R&D data for India, this paper examines the extent to which India’s recent growth experience can be explained by R&D, international R&D spillovers, catch-up to the technology frontier and financial liberalization. Furthermore, the paper also tests whether any of...
