This paper presents estimates of the unification bonus for East Germans over the period 1991 to 1998. The unification bonus is defined as the discounted value of the difference between a person's actual income and his or her counterfactual real income stream forecast for a hypothetical continuation of economic life in a static GDR. The two main issues tackled in this study are the construction of valid deflators for a comparison of real incomes during the transition from a centralized to a market economy and the estimation of plausible counterfactual income streams. Our central result is that 19 percent of East Germans received a present value malus and so can be regarded as unification losers but that the aggregate bonus is ten times the size of the aggregate malus of the sample
