The existing literature implicitly or explicitly assumes that securities lenders primarily respond to demand from borrowers and reinvest their cash collateral through short-term markets. Using a new dataset that matches every U.S. life insurer's bond portfolio, as well as their lending and...

Banks, life insurers, and commercial mortgage-backed securities (CMBS) lenders originate the vast majority of U.S. commercial real estate (CRE) loans. While these lenders compete in the same market, they differ in how they are funded and regulated, and therefore specialize in loans with...

Insurance companies often follow highly correlated investment strategies. As major investors in corporate bonds, their investment commonalities subject investors to fire-sale risk when regulatory restrictions prompt widespread divestment of a bond following a rating downgrade. Reflective of...

This paper explores the economic issues related to systemically important insurance companies, using an example from the Great Depression, the National Surety Company. National Surety was a large and diverse insurance company that experienced a major crisis in 1933 due to losses from its...

This paper studies how over-the-counter market liquidity is affected by securities lending. We combine micro-data on corporate bond market trades with securities lending transactions and individual corporate bond holdings by U.S. insurance companies. Applying a difference-in-differences...

A number of researchers have recently argued that the growth of the shadow banking system in the years preceding the recent U.S. financial crisis was driven by rising demand for "money-like" claims — short-term, safe instruments (STSI) — from institutional investors and nonfinancial firms....

In a market-based democracy, we model different constituencies that disagree regarding the likelihood of economic disasters. Costly public policy initiatives to reduce or eliminate disasters are assessed relative to private alternatives presented by financial markets. Demand for such public...

The Basel Committee promulgates bank regulatory standards that many major economies enact to a significant extent. One element of the Basel III capital standards is a system of capital surcharges for global systemically important banks (G-SIBs). If the purpose of the surcharges is to ensure the...

Margin regulation raises two policy concerns. First, an alignment of margins to volatility can amplify procyclicality, leading to a build-up of excess leverage in good times and a forced deleverage in bad times. Second, competition among central counterparties (CCPs) can result in lower margin...

The concentration of risk within financial system is considered to be a source of systemic instability. We propose a theory to explain the structure of the financial system and show how it alters the risk taking incentives of financial institutions. We build a model of portfolio choice and...
