In 2003 the Government of Ghana established a National Health Insurance Scheme (NHIS) to improve health care access for Ghanaians and eventually replace the cash-and-carry system. This study evaluates the NHIS to determine whether it is fulfilling its purpose in the context of the Millennium...

The euro area is experiencing a severe and highly complex crisis. It comprises three problem areas, the difficulties of some highly indebted European sovereigns to ascertain funding at palatable cost, the disconcerting fragility of the European banking system and disappointing growth prospects...

We provide evidence that motorists respond to short-run fluctuations in fuel prices at the gas pump and not on the road. Employing variants of censored panel regression to control for unobserved heterogeneity and censoring of the dependent variable, we find that the fuel price has a large and...
