This paper apportions responsability for inefficency in a market for state contingent claims between market makers and traders. We specifically examine the origins of a frequently observed distortion in the market for bets in horseraces- the favorite- longshot bias. Previous studies rationalise...

This paper reviews the application of OR to financial markets. After considering reasons for the attractiveness of general finance problems to Or researchers, the main types of financial market problem amenable to OR are identified, and some of the many problems solved using OR are documented.

A constraint satisfaction problem requires a value, selected from a given finite domain, to be assigned to each variable in the problem, so that all constraints relating the variables are satisfied. Many combinatorial problems in operational research, such as schedulling and timetabling, can be...

Empirical research on group lending is extensive, but without allowance for collateral to mitigate strategic default. Indeed, lack of credit access has motivated microcredit in rural areas of developing countries, where agents with collateral are very rare. As rural communities have tight-knit...

In a global context foreign direct investment (FDI) and migration substitute one another in the matching process between workers and firms. However, as labor flows can lead to the formation of business networks, migration can actually facilitate FDI in the long-run. We first present a stylized...

Estimates for the U.S. suggest that in some sectors productivity enhancing reallocation is the dominant factor in accounting for productivity growth. An open question is whether reallocation is always productivity enhancing. Specifically, in developing countries, market concentration, or...

We introduce a new nonparametric approach for estimating a simple varying coeffcient model with a unit root nonstationarity. Our method is based on a piecewise local least squares principle and is computationally simple to implement. We establish its asymptotic properties and evaluate its...

We study experimentally the effect on individual behavior of comparative, but payoff-irrelevant, information in a near-minimal group setting. Specifically, in each round, group members see the groups' cumulative payoffs, which consist of an aggregation of the earnings of each member of the group...

This paper provides a set-theoretic model of knowledge and unawareness. A new property called Awareness Leads to Knowledge shows that unawareness of theorems not only constrains an agent's knowledge, but also, can impair his reasoning about what other agents know. For example, in contrast to Li...
