Joseph Pollack

I'm a researcher in Economics focusing on firm dynamics and volatility. My work investigates the relationship between micro and macro-level economic fluctuations, particularly examining how firm-level volatility relates to aggregate economic volatility. I previously conducted research exploring convergent trends between firm-level and aggregate production volatility, challenging earlier findings about their divergence.

My interests center on understanding how individual firm behavior and characteristics aggregate to economy-wide patterns. I'm particularly interested in how economic shocks, like the 2007 financial crisis, affect both firm-level and aggregate volatility measures. My research has shown that firm volatility is primarily driven by covariance elements rather than compositional effects, contributing to our understanding of business cycle dynamics.

I aim to bridge microeconomic and macroeconomic perspectives in my research, using both theoretical frameworks and empirical analysis to better understand economic fluctuations. This work has implications for both corporate strategy and economic policy, particularly in how we think about risk management and economic stability at different scales of analysis.
