In the United States, the income share of the top 5% income group is acyclical over the business cycle. This study attempts to explain the cyclical behavior of the income distribution over the business cycle, particularly focusing on the top 5% income earners' share, using a heterogeneous agent model featuring a choice to become an entrepreneur. The model economy successfully reproduces the acyclical behavior of the income share of the top 5%. During expansions, relatively more people become entrepreneurs at the top, which offsets the decline in the income share of the high‐income earners from workers' side.
