This paper models the supply of perishable goods within a randon framework. Perishability affects a large group of goods usually traded in the economy such as fruits and vegetables, newspapers, medicine drugs, a.s.o.. Surprisingly, one cannot find in the literature a decision model for suppliers...

A "dispersion" specifies the relative probability between any two elements of a finite domain. It thereby partitions the domain into equivalence classes separated by infinite relative probability. The paper's novelty is to numerically represent not only the order of the equivalence classes, but...

We provide two, new simple proofs of Afriat's celebrated theorem..

Motivated by the slow diffusion of generic drugs and the increase in prices of brand-name drugs after generic entry, I incorporate consumer learning and consumer heterogeneity into an empirical dynamic oligopoly model. In the model, firms choose prices to maximize their expected total discounted...

This paper develops a dynamic stochastic model to examine the joint patent application and renewal behavior under an international patent protection regime. This framework makes it possible to utilize both the cross-sectional (multi-country filing) and the time-series (patent renewal) dimensions...

We give two procedures for determining whether efficient Pareto improving local changes are possible. When they are, the procedures compute for them. Any procedure generating efficient and Pareto improving changes can be replicated by these procedures. The two programs form a striking duality....

This paper analyzes investment effect of tradable permit program (TPP) when emission permits are bankable and there is technological uncertainty regarding abatement cost. In the absence of uncertainty, a firm's incentive to environmental investment decreases under a bankable TPP compared to a...

The main goal of this paper is to investigate the role of campaign fund in congressional careers. To achieve this goal, we specify a dynamic model of career decisions of a member of Congress. In particular, we model how the amount of campaign funds raised affects the probability of winning...

Based on a simple open economy framework, this analysis rationalizes the existence of “fear of floatingâ€-type responses and uncovers some important implications about to role of pass-through effects and contractionary depreciations. By examining how the optimal monetary response varies...

Price caps are a popular form of monopoly price regulation. One of its disadvantages is the perverse incentives that regulated firms might have to scamp on cost reducing effort during the last years before a price review. In order to avoid this problem a “rolling cap†contract was...
