We survey the literature analysing the price formation and trading process, and the consequences of market organization for price discovery and welfare. We develop a united perspective on theoretical, empirical and experimental approaches. We discuss the evidence on transaction costs and the...

This paper offers a theory of development which links the degree of market incompleteness to capital accumulation and growth. At early stages of development, the presence of indivisible projects limits the degree of risk-spreading (diversification) that the economy can achieve. The desire to...

We analyse an economy where production is subject to moral hazard. The degree of the incentive (agency) costs introduced by the presence of moral hazard naturally depends on the information structure in the economy; it is cheaper to induce correct incentives in a society which possesses better...

This paper studies equilibria for economies characterized by moral hazard (hidden action), in which the set of contracts marketed in equilibrium is determined by the interaction of financial intermediaries. The crucial aspect of the environment that we study is that intermediaries are restricted...

We show that direct investments by consumers without the use of financial intermediaries can efficiently allocate financial capital to firms seeking funding for production of a novel consumption good. In our setting, consumers are also investors, and their privately known consumption preferences...

We use a controlled economic experiment to examine the implications of asymmetric information for informational linkages between a stock market and a traded call option on that stock. The setting is based on the Kyle model and Back (1993). We find that an insider trades aggressively in both the...

We analyze a standard environment of adverse selection in credit markets. In our environment, entrepreneurs who are privately informed about the quality of their projects need to borrow in order to invest. Conventional wisdom says that, in this class of economies, the competitive equilibrium is...

Money management is an activity in which agents are often evaluated on the basis of their relative performance. In this article we consider an oligopolistic market in which some informed fund managers aim at maximizing their relative performance, rather than their absolute performance. First, we...

In an economy where entrepreneurs with unequal ‘abilities’ face alternative investment projects, which differ in their degree of risk and productivity, we analyse the Nash equilibrium contracts arising from a banks-borrowers game in the context of asymmetric information. We show that, for a...

Insider trading in the credit derivatives market has become a significant concern for regulators and participants. This paper attempts to quantify the problem. Using news reflected in the stock market as a benchmark for public information, we report evidence of significant incremental...
