Risk-Taking, Market Selection and Income Mobility:Theory and Applications


We develop a Markov mobility model to study how market competition, as the market deepens to the extent that entrepreneurial undertaking becomes viable, effectively screens the individuals/households’ entrepreneurial abilities by rewarding those with high abilities and punishing the less able, and, as a consequence, how the screening leads to intergenerational income mobility in favor of the former even when and if the latter is privileged to initially possess more wealth than the former. Our theory has implications for understanding the income and wealth mobility, especially in the economies, such as the post-reform China and the post-apartheid South Africa, wherein the expanding market order has been rapidly reshaping the economic life that used to be deeply embedded in the social fabric and long entrenched institutions, which are often against the logic of the market. We confront our theoretical predictions with a dataset regarding income mobility of about 1500 households in rural China during the period 1989-2009 and empirical evidence from the history of other economies as well.
