We represent interval ordered homothetic preferences with a quantitative homothetic utility function and a multiplicative bias. When preferences are weakly ordered (i.e. when indifference is transitive), such a bias equals 1. When indifference is intransitive, the biasing factor is a positive...

This paper re-examines gender wage differences, taking into account not only worker characteristics but also job characteristics. Consideration of a wide set of “job quality” indicators can explain a fraction of the wage gap that would otherwise be attributed to pure wage discrimination. In...

This paper studies monetary and fiscal policy interactions in a two country model, where taxes on firms’ sales are optimally chosen and the monetary policy is set cooperatively. It turns out that in a two country setting non-cooperative fiscal policy makers have an incentive to change taxes on...

We derive a new inequality for uniform deviations of averages from their means. The inequality is a common generalization of previous results of Vapnik and Chervonenkis (1974) and Pollard (1986). Using the new inequality we obtain tight bounds for empirical loss minimization learning.

We develop a setting with weak intellectual property rights, where firms' boundaries, location and knowledge spillovers are endogenous. We have two main results. The first one is that, if communication costs increase with distance, entrepreneurs concerned about information leakage have a benefit...

The Maximum Capture problem (MAXCAP) is a decision model that addresses the issue of location in a competitive environment. This paper presents a new approach to determine which store’s attributes (other than distance) should be included in the new Market Capture Models and how they ought to...

Minkowski's ?(x) function can be seen as the confrontation of two number systems: regular continued fractions and the alternated dyadic system. This way of looking at it permits us to prove that its derivative, as it also happens for many other non-decreasing singular functions from [0,1] to...

Structural equation models (SEM) are commonly used to analyze the relationship between variables some of which may be latent, such as individual ``attitude'' to and ``behavior'' concerning specific issues. A number of difficulties arise when we want to compare a large number of groups, each with...

Organizations often face the challenge of communicating their strategies to local decision makers. The difficulty presents itself in finding a way to measure performance wich meaningfully conveys how to implement the organization's strategy at local levels. I show that organizations solve this...
