Abstract
We examine the role of labor informality in shaping macroeconomic volatility in a small open economy. Using a DSGE model calibrated to Colombia, we focus on worker-level rather than firm-level informality. The model features heterogeneous households and a segmented labor market with formal and informal workers, incorporating wage rigidities and productivity differences. Our results show that higher informality amplifies the volatility of consumption and investment, which is consistent with the empirical evidence. The mechanism operates through the interaction of wage rigidities in the formal sector with lower productivity of informal workers. Quantitatively, the model accounts for a significant share of the observed link between informality and volatility. These findings highlight how labor market frictions magnify business cycle fluctuations in emerging economies. *****RESUMEN: En este trabajo, examinamos el papel de la informalidad laboral en la volatilidad macroeconómica en una economía pequeña y abierta. Para ello, utilizamos un modelo DSGE calibrado para Colombia en el que nos centramos en la informalidad a nivel de los trabajadores, en lugar de a nivel de las empresas. El modelo considera hogares heterogéneos y un mercado laboral segmentado, con trabajadores formales e informales, rigideces salariales y diferencias de productividad. Los resultados muestran que una mayor informalidad aumenta la volatilidad del consumo y la inversión, lo que concuerda con la evidencia empírica. Este efecto se produce a través de la interacción entre las rigideces salariales del sector formal y la menor productividad de los trabajadores informales. Cuantitativamente, el modelo explica una parte significativa de la relación observada entre la informalidad y la volatilidad. Estos resultados ponen de manifiesto cómo las fricciones del mercado laboral amplifican las fluctuaciones del ciclo económico en las economías emergentes.
