We analyse the magnitude and the causes of the low formal employment rate of the Roma in Hungary between 1993 and 2007. The employment rate of the Roma dropped dramatically around 1990. The ethnic employment gap has been around 40 percentage points for both men and women and has remained remarkably stable. Differences in education are the most important factor behind the gap, the number of children is important for female employment and geographic differences play little role once education is controlled for. Conditional on employment, the gap in log earnings is 0.3, and half of it is explained by educational differences.
