We survey 861 finance academics, professionals, and public sector regulators and policy economists about climate finance topics. They identify regulatory risk as the top climate risk to businesses and investors over the next five years, but they view physical risks as the top risk over the next...

A number of studies have identifed patterns of positive correlation of returns, or comovement, among different traded securities. We distinguish three views of such comovement. The traditional 'fundamentals' view explains the comovement of securities through positive correlations in the rational...

In the classic theory of Scholes (1972), demand curves for stocks are kept flat by riskless arbitrage between perfect substitutes. In reality, however, individual stocks do not have perfect substitutes. We develop a simple model of demand curves for stocks in which the risk inherent in arbitrage...

Economists have long argued that financial markets can improve the allocation of capital across an economy's investment opportunities, but empirical evidence to support this belief has been lacking. This paper presents evidence from 65 countries which suggests that financial markets do indeed...

Almost $10 trillion is benchmarked to Morgan Stanley Capital International's Developed, Emerging, Frontier, and standalone market indexes. Reclassifications from one index to another require thousands of investors to decide how to react. We study a comprehensive sample of past reclassifications...
