The political business cycle under rational voting behavior

This essay argues that politically motivated business cycles could persist in a democratic society even if the electorate votes in a rational, fully informed manner, provided that government policymakers have the means to systematically generate macroeconomic fluctuations. This cyclic outcome reflects the pReferences of an electorate that is composed of imperfectly altruistic voters belonging to different overlapping generations. Since each generation has a different horizon over which it would like to have elected politicians provide an optimal economic policy plan, an intergenerational conflict of interests situation arises. This conflict is placed into an explicit political context, whereby cycles become generated under the institutional constraint of periodic elections.     

Time-consistent monetary policy under output persistence

This note merges the fact that real activity is persistent with a Barro-Gordon type model of endogenous monetary policy. It shows that persistence crucially affects policy choices. This applies in non-cooperative games with a finite horizon, and in games with an infinite horizon. Always, enforceable inflation announcements move higher when output persistence increases. Policymakers who discount future utility by 10% annually produce about ten times as much inflation under near-hysteresis as in a natural-rate scenario. A change in the policymaker's time preference may affect inflation both ways, depending on present time preference and persistence.
