This paper questions the positive relationship between HIV prevalence and income in Sub-Saharan Africa. In this paper, we hypothesize that a greater economic instability would reduce the incentives to engage in self-protective behaviors inducing people to increasingly take the risk of...

So-called "spurious regression" relationships between random-walk (or strongly autoregressive) variables are generally accompanied by clear signs of severe autocorrelation in their residuals. A conscientious researcher would therefore not end an investigation with such a result, but would likely...

This paper uses comparable international data to examine the extent and wage effects of skill mismatches among European university graduates. The results show that the mismatched earn on average 11.7% less than their well-matched counterparts. This effect, however, cannot be regarded as constant...

In this paper I examine the Okun–Friedman hypothesis of the link between inflation and inflation uncertainty using historical international data on the monthly CPI. An indicator of inflation uncertainty at the two-years-ahead horizon is derived from a time-series model of inflation with...

In this study we test the mean-variance capital asset pricing model (CAPM) developed by Sharpe (1965) Lintner (1966) on individual stocks traded at Karachi Stock Exchange (KSE), the main equity market in Pakistan for the period 1993-2004 using daily and monthly data. The empirical findings do...

This paper explores the connection between education and wage inequality in nine European countries. We exploit the quantile regression technique to calculate returns to lower secondary, upper secondary and tertiary education at different points of the wage distribution. We find that in most...
