In a capitalist economy prices serve to equilibrate supply and demand for goods and services, continually changing to reallocate resources to their most efficient uses. Secondary stock market prices, however, often viewed as the most 'informationally efficient' prices in the economy, have no...

The electronic trading system Xetra of the German Security Exchange provides a unique data source on the equity trades of 451 large traders located in 23 different cities and 8 European countries. We explore informational asymmetries across the trader population: Traders located outside Germany...

If entrepreneurs are liquidity constrained and cannot borrow to operate on an efficient scale, those with more personal wealth should do better than those with less wealth. We investigate this hypothesis using a unique datset from Norway. Consistent with liquidity constraints being present, we...

The extreme levels of stock price volatility found during the Great Depression have often been attributed to political uncertainty. This Paper performs an explicit test of the Merton/Schwert hypothesis that doubts about the survival of the capitalist system were partly responsible. It does so by...

This paper reconsiders the role of foreign investors in developed country equity markets. It presents a quantitative model of trading that is built around two new assumptions about investor sophistication: (i) both the foreign and domestic populations contain investors with superior information...

In an economy à la Diamond and Dybvig (1983), we present an example in which foreign lenders find it profitable to invest in an emerging market if, and only if, the emerging market government imposes taxes on short-term capital inflows. This implies that capital controls that are effective in...

We develop a model of price formation in a dealership market where monitoring of the information flow requires costly effort. The result is imperfect monitoring, which creates profit opportunities for speculators, who do not act as dealers but simply monitor the information flow and quote...

We analyse the effects of insider trading on real investment and welfare, and the consequences of different regulatory policies: a disclose-or-abstain rule, ‘fair’ disclosure, laissez-faire and forbidding insider trades based on ‘precise’ information. We perform the analysis in a model...

We propose a critical review of recent developments in exchange rate economics. This new strand of research is motivated by some very stark empirical evidence, relating exchange rate returns to order flow. Plenty of empirical evidence shows that order flow, i.e. the imbalance in the sequence of...

We show that a cross-listing allows a firm to make better investment decisions because it enhances stock price informativeness. This theory of cross-listings yields a rich set of new predictions. In particular, it implies that the sensitivity of investment to stock prices should be larger for...
