This article studies the effects of Behaviour-Based Price Discrimination (BBPD) in a horizontally and vertically differentiated duopoly. In a two-period model, firms are allowed to condition their pricing policies on the past purchase behaviour of consumers. The paper shows two different types...

The HIV/AIDS epidemic has dramatically altered patterns of morbidity and mortality in Sub-Saharan Africa with potential consequences on fertility and population dynamics. We take advantage of a unique data-set collected in Cameroon among HIV positive patients and estimate the relationship...

Intermediaries helping individuals and rms with the government bureaucracy are common in developing countries. Although such bureaucracy intermediaries are, anecdotally,linked with corruption and welfare losses, few formal analyses exist. In our model, a government license can benet individuals....

In this paper, we warn on the overoptimistic conclusions led by weak instruments testing when good leverage points are present in the first stage of an IV estimation. Some simulations and an empirical application are provided to illustrate the point raised.

This paper describes the Stata implementation of Baltagi and Li's (2002) series estimator of partially linear panel data models with fixed effects. After a brief description of the estimator itself, we describe the new command xtsemipar. We then simulate data to show that this estimator performs...

Across African countries, prevention policies are unrelated to the prevalence of HIV/AIDS and, even in countries in which they were successful, these policies are often unstable or reversed. To explain these two puzzles, we propose a simple political economy model that examines how prevention...

We study the impact of a large-scale economic crisis on gender equality, using historical data from Kazakhstan in the late 19th – early 20th century. We focus on sex ratios (number of women per man) in Kazakh nomadic population between 1898 and 1908, in the midst of large-scale Russian...

Firm entry and exit flows in the retailing and consumer services may be viewed as market equilibrating processes. Local markets with considerable market room and high unemployment ought to be characterized by high subsequent entry rates and low exit rates. However, lack of entrepreneurial...
