This paper studies the redistributive effects of government partisanship on economic sectors in a parliamentary democracy. Based on a rational partisan perspective and policy-induced campaign contribution models, we expect that once in office, ideologically different parties deliver favorable policies to different industries in order to enrich their electoral and sector-specific supporters. Using daily stock market data, we empirically evaluate whether and how the mean and the volatility of returns to four important economic sectors covaried with the electoral prospects of a right-/left-leaning coalition in Germany from 1991 to 2005. This sheds light on the magnitude of sector-specific redistribution to be expected from ideologically different governments holding office. The results show that the mean and the volatility of defense and pharmaceutical sector returns increase if a right-leaning government is becoming more likely to win the upcoming election. In contrast, an increase in the probability of a left-leaning government triggers higher returns to the alternative energy sector and increases the volatility of consumer sector returns. Thus, our estimates partly support the idea that parties redistribute across sectors.
