Recent empirical studies show that the intergenerational persistence of economic status in the U.S. is much higher than previously thought. We develop a quantitative theory of inequality and intergenerational transmission of human capital where parents invest in early and college education of their children subject to borrowing constraints. Children differ exogenously in innate abilities, which can be correlated with their parent's innate ability. An important feature of the environment is that the quality of early education determines the probability of college completion. We calibrate a stationary equilibrium of this economy to relevant statistics in aggregate U.S. data, and use it to investigate the sources of inequality and persistence in earnings. In our benchmark model, about half of the intergenerational persistence and one fourth of the inequality in earnings are accounted for by endogenous investments in education. We find that early investments in education account for most of the endogenous persistence in earnings, while college education generates most of the endogenous inequality in earnings. Our theory is suited to study the effect of educational policies on the persistence of inequality. We show that public resources devoted to early education have the largest impact on earnings mobility. Moreover, non-progressive college subsidies generate more intergenerational persistence of earnings.

We analyze the joint impact of employment protection and informality on macroeconomic volatility and the propagation of shocks in emerging economies. For this, we propose a small open economy business cycle model with frictional labor markets, labor regulation, and an informal sector, modeled as self-employment. The model is calibrated to the Mexican economy, in particular to business cycle moments for employment and informality obtained from our own calculations with the ENOE survey for the period 2005-2016. We show that international interest rate shocks, which affect specifically job creation in the formal sector, are key to obtain a counter-cyclical informality rate. In our model both the economy without an informal sector and the economy with informality but a lower burden of labor regulation feature higher volatility in employment but smaller fluctuations in TFP and output.

Financial crises in emerging economies are accompanied by a large fall in total factor productivity. We explore the role of financial frictions in exacerbating the misallocation of resources and explaining this drop in TFP. We build a two-sector model of a small open economy with a working capital constraint to the purchase of intermediate goods. The model is calibrated to Mexico before the 1995 crisis and subject to an unexpected shock to interest rates. The financial friction generates an endogenous fall in TFP and output and can explain more than half of the fall in TFP and 74 percent of the fall in GDP per worker.
