This paper presents new evidence on the study of income mobility in Ecuador over the period 2004 - 11. We utilize longitudinal data of individual income tax returns to measure income mobility both at the top and at the middle of the income distribution, and we find three main empirical results. First, income mobility in Ecuador is low for top incomes: the probability of remaining in the top 1 per cent after one year is nearly 66 per cent, and it remains stable by the end of the period. Second, there is a high degree of mobility for the rest of the income distribution. Individuals are more likely to experience upward mobility than downward mobility, especially those in the middle income defiles. Third, regression results suggest that the initial position in the income distribution is highly related to the probability of upward or downward mobility. Moreover, having a high-school degree is associated with upward income movements. To our knowledge, this is the first time that research uses data from tax returns to measure income mobility in this South American economy.
