The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

Tournaments are designed to enhance participants’ effort and productivity. However, ranking near the top may increase psychological pressure and reduce performance. We empirically study the impact of interim rank on performance using data from international diving tournaments. We find...

There is little evidence on the joint evolution of gender differences in wages and other job amenities. We analyze gender differences in wages and workplace safety using 9 years of Italian administrative micro-level data. We document that a decline in the gender wage gap was accompanied by a...

Little is known about the effects of revealing information on relative performance during a dynamic tournament. We empirically study the impact of interim rank on risk taking and performance using data on professionals competing in tournaments for large rewards. As our data allows us to observe...

We study the repeal of a regulation that imposed maximum wholesale and retail markups for all but five fresh fruits and vegetables. We compare the prices of products affected by regulation before and after the policy change and use the unregulated products as a control group. We find that...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

A definition of set-wise differentiability for set functions is given through refining the partitions of sets. Such a construction is closely related to the one proposed by Rosenmuller (1977) as well as that studied by Epstein (1999) and Epstein and Marinacci (2001). We present several classes...

Entry into licensed professions requires meeting competency requirements, typ- ically assessed through licensing examinations. This paper explores whether the number of individuals attempting to enter a profession (potential supply) affects the difficulty of the entry examination. The empirical...

We measure friction in the matching of students and law schools as the number of unnecessary student applications and school admissions that have to be undertaken per actual matriculation. We show that friction increases with student and school attractiveness, but decreases for top schools and...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...
