China's securities markets are unlike those of Amsterdam, London or New York. Those markets evolved over centuries from myriad interactions among those seeking finance on the one hand and savers seeking rewarding investments on the other. Such spontaneous securities markets did emerge throughout...

A large amount of activity in the financial sector occurs in secondary financial markets, where securities are traded among investors without capital flowing to firms. The stock market is the archetypal example, which in most developed economies captures a lot of attention and resources. Is the...

Discussions of financial risk often fail to distinguish between risks that are consciously borne and those that are not. To understand the breeding conditions for financial crises the prime focus of concern should not be simply on large risk-taking per se, but on the unintended, or unanticipated...

We study climate and macroprudential policies in an economy with financial frictions. Using a dynamic stochastic general equilibrium model featuring both a pollution market failure and a market failure in the financial sector, we explore transition risk - whether ambitious climate policy can...

This paper reviews the evolving literature that links financial development, financial crises, and economic growth in the past 20 years. The initial disconnect--with one literature focusing on the effect of financial deepening on long-run growth and another studying its impact on volatility and...

Do sophisticated international financial markets obviate the need for an active union-wide authority to orchestrate fiscal transfers between countries to provide adequate insurance against country-specific economic fluctuations? We argue that they do. Specifically, we show that in a benchmark...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

This paper argues that firms have an informational advantage over consumers in selecting arbitrators in consumer arbitration. We document how the selection process impacts arbitration outcomes by studying roughly 9,000 consumer arbitration cases in the securities industry. Securities disputes...

The facts suggest that demand for financial services increased, perhaps temporarily, rather than suggesting a changing distortion...

In a model with heterogeneous-risk-aversion agents facing margin constraints, we show how securities' required returns are characterized both by their betas and their margin requirements. Negative shocks to fundamentals make margin constraints bind, lowering risk-free rates and raising Sharpe...
