This paper endogenizes both market transparency and product differentiation in a model of informative advertising á la Grossman and Shapiro (1984). We find, contrary to Schultz (2004), that an increase in market transparency raises firm profits but has no effect on product differentiation. We...

This paper analyses the impact of income inequality on public good provision in an experimental setting. A sample of secondary school students were recruited to participate in a simple linear public goods game where income heterogeneity was introduced by providing participants with unequal token...

number of studies have contended that it is challenging to explain exchange rate movement with macroeconomic fundamentals. A naive model such as a random walk forecasts exchange rate movements more reliably than existing structural models. This paper confirms that it is possible to improve the...

This paper investigates whether the risk faced by rural farmers in Zimbabwe could potentially be managed by using community-based wildlife conservation. Community-based wildlife conservation could be an additional asset in the rural farmers. investment portfolio thereby potentially diversifying...

How do you estimate poverty, inequality and earnings when the income variable consists of a combination of point-identified, interval-identified, and missing observations? This paper proposes a unifying theoretical approach to the problem of deriving point estimates when such data are present....
