This study presents an overlapping-generations model featuring endogenous growth, collective wage-bargaining, and probabilistic voting over fiscal policy. We characterize a Markov-perfect political equilibrium of the voting game within and across generations and show the following results. First, greater bargaining power of unions lowers the growth rate of capital and creates a positive correlation between unemployment and government debt. Second, greater political power of the old lowers the growth rate and shifts government expenditure from the unemployed to the old. Third, a balanced budget requirement increases the growth rate but may benefit the old at the expense of the unemployed.
