My fields of specialization are applied microeconometrics and applied microeconomics. Two central themes are firm production and pricing, and labor-management relations. The observed gap between an input’s marginal product and its measured payment combined with the ubiquity of firm-level productivity variation and persistence are empirical regularities that have shaped my research agenda. Being driven by a curiosity in real world phenomena and highly valuing the empirical validation of economic models, I employ various quantitative methods and a wide variety of micro-level datasets in European, Latin American and Asian countries in my empirical investigations.
