Chapter 1: Financial Consolidation and the Cyclicality of Corporate FinancingWe study the impact of the concentration and complexity of the banking sector on firms’ financing and investment behavior over the business cycle. We find that, after the late 1990s, while debt issuance remained procyclical for U.S. firms of all sizes, equity issuance and liquidity accumulation switched from countercyclical to procyclical for small and medium- sized publicly-traded firms. Using matched firm-bank data, we provide evidence that bank consolidation contributed to this change. We rationalize these findings in a general equilibrium business cycle model. After bank consolidation, the weakening in firms’ bargaining power and relational ties with banks enhances firms’ precautionary demand for liquidity and equity issuance incentives following positive shocks. The change in financing behavior increases investment and employment sensitivity to aggregate productivity shocks. Chapter 2: Monetary Policy and Firm Heterogeneity: The Role of Leverage Since the Financial Crisis We study how leverage determines firm-level responses to monetary policy. Using both high-frequency financial market and quarterly investment data, we find that the role of leverage in monetary transmission changed around the financial crisis of 2007-09. Firms with high leverage were less responsive to monetary policy shocks in the pre-crisis period but have become more responsive since the crisis. The higher responsiveness is driven by firms whose leverage is more dependent on long-term debt, suggesting an outsize role for monetary policy affecting long-term funding conditions since the crisis. We also find suggestive evidence for transmission through changes in monetary policy uncertainty. Chapter 3: The International Spillover Effects of US Monetary Policy Uncertainty An extensive literature studies the international transmission of US monetary policy surprises (shifts in expected path of the policy rate). In this paper we show that changes in uncertainty around the expected path constitute an important additional dimension of spillover effects to global bond yields. In advanced countries, it is the term premium component of yields that responds to uncertainty. We find that this can be explained by an international portfolio balance mechanism. In contrast, for emerging countries it is the expected component of yields that reacts to uncertainty. This can be rationalized from a flight to safety channel. We find heterogeneity in the country-level response to uncertainty only in emerging countries and it is driven by the degree of financial openness. Finally, equity markets in both advanced and emerging countries also respond to US monetary policy uncertainty.
