Voters' commitment problem and reforms in welfare programs

When will a vote-seeking government pursue unpopular welfare reforms that are likely to cost it votes? Using a game-theoretical model, we show that a government enacts reforms that are unpopular with the median voter during bad economic times, but not during good ones. The key reason is that voters cannot commit to re-elect a government that does not reform during bad times. This voters’ commitment problem stems from economic voting, i.e., voters’ tendency to punish the government for a poorly performing economy. The voter commitment problem provides an explanation for the empirical puzzle that governments sometimes enact reforms that voters oppose.
