On June 21, 2011, Catalina Granda-Carvajal defended her dissertation, “Essays on the Macroeconomic Effects of the Unofficial Sector.” Under the valuable supervision and support of her advisor, Prof. Christian Zimmermann, Catalina’s thesis focuses on how the unofficial sector and its intrinsic characteristics are related to aggregate fluctuations. At an empirical level, she determines how business cycle stylized facts vary across countries with the extent of the shadow economy and compares the resulting patterns with predictions from existing models featuring underground activities. Also, she incorporates an irregular sector into a real business cycle model to challenge the notion that fluctuations in the official and unofficial sectors are negatively correlated. Using a similar theoretical framework, she finally addresses how informal firms’ limited access to credit affects macroeconomic and firm volatility.
Pieces of Catalina’s dissertation have been presented in a couple of international conferences and a section was selected for publication at the International Economic Journal last December. In addition to her thesis, she has taken part in an interdisciplinary project on options for brownfields revitalization in Connecticut under the supervision of Prof. Kathleen Segerson. She currently holds a tenure-track position at Universidad de Antioquia in Medellín (Colombia).
