Several theoretical explanations have been proposed to explain the mixed evidence of economic voting in post-communist countries. Using aggregate-level data, this article relaxes the assumption of parameter constancy and employs rolling regression analysis to track fluctuations in parameters over time. The results contradict the existing theories of economic voting in postcommunist countries. As an alternative explanation, the article suggest that voters have a level of pain tolerance below which the economy will not play a role in evaluations of the government; voters will use economic indicators to punish and reward incumbent government only if the economic indicators exceed their pain tolerance. For example, in the Czech Republic, voters will not start punishing the incumbent party until inflation climbs above 13.44%. However, Czech voters are less tolerant of unemployment and will punish the incumbent when unemployment exceeds 8.82%.
