The idea that a trade-off exists between current levels of consumption and future levels of human capital is modeled. As shocks in international commodity prices affect income and modify the optimal consumption basket, household members adjust their time preferences between school and work. As a result, the dynamics of human-capital accumulation may be affected and, in cases in which commodity production and trade play a significant role in the economy, such dynamics may also have an impact on economic growth and the composition of economic sectors. Using a dynamic CGE model and Colombian macroeconomic data, we showed how shocks in commodity prices determined households’ educational demands and, at the same time, the composition of the labor market.
