Jorge De la Roca is writing his PhD Dissertation under the supervision of IMDEA Research Professor Diego Puga. De la Roca completed his BA in Economics at Universidad del Pacífico in Lima, and his MA in Economics and Finance at the Center for Monetary and Financial Studies (CEMFI), where he is currently a PhD candidate in Economics. His research interests comprise urban economics, economic geography and labor economics. His first paper estimates the extent of agglomeration economies in Spain and explores how agglomeration premia accumulate over time. More broadly, Mr. de la Roca is interested in pursuing structural estimation of the contributions of potential channels to the formation of agglomeration economies in cities.
