In this paper, we apply a general equilibrium occupational choice model to the study of the impact of optimism on the earnings of entrepreneurs and workers. We extend the work of Lucas (1978 Bell Journal of Economics 9, 508–523) by assuming a fraction of individuals are optimistic about their ability as entrepreneurs. The model shows that optimism leads to a misallocation of talent and inputs, which raises input prices and lowers output. The model is calibrated to match salient features of the UK economy and the British Household Panel Survey. The calibration shows that optimism can account for more than half of the size of the entrepreneurial earnings puzzle in the UK.

乐观能解决创业者的收入难题吗？*

在本文中，我们应用一般均衡职业选择模型来研究乐观情绪对企业家和工人收入的影响。我们通过假设一小部分人对他们作为企业家的能力持乐观态度来扩展 Lucas (1978 Bell Journal of Economics 9 , 508–523)的工作。该模型表明，乐观情绪会导致人才和投入的错配，从而提高投入价格并降低产出。该模型经过校准以匹配英国经济和英国家庭追踪调查的显着特征。校准表明，乐观情绪可以占英国企业家收入难题的一半以上。
