This paper considers an economy in which policyniakers with different preferences concerning fiscal policy alternate in office as a result of democratic elections. It is shown that in this situation government debt becomes a strategic variable used by each policymakerto influence the choices of his successors. In particular, if different policymakers disagree aboutthe desired composition of government spending betweentwo public goods, the economy exhibits a deficits bias. Namely, in this economy debt accumulation is higher than it would be with a social planner. According to the results ofour model, the equilibrium level of governmentdebt is larger: the larger isthe degree of polarization between alternating governments;and the morelikely it is that the current government will not be reelected. The paper has empirical implications which may contribute to explain the current fiscalpolicies in the United States and in severalother countries.
