General equilibrium models have been used for decades to obtain insights into the economic implications of policies and decisions. Despite successes, however, these economic models have substantive limitations. Many of these limitations are due to computational and methodological constraints that can be overcome by leveraging recent advances in computer(More)
Both distributed systems and multicore systems are difficult programming environments. Although the expert programmer may be able to carefully tune these systems to achieve high performance, the non-expert may struggle. We argue that high level abstractions are an effective way of making parallel computing accessible to the non-expert. An abstraction is a(More)
This paper analyzes the distortions created by taxation and the features of tax systems that minimize such distortions (subject to achieving other government objectives). It starts with a review of the theory and practice of deadweight loss measurement, followed by characterizations of optimal commodity taxation and optimal linear and nonlinear income(More)
The author proposes a strategic model of entry that allows for positive and negative spillovers among firms. The model is applied to a novel data set containing information about the store configurations of all U.S. regional shopping centers and is used to quantify the magnitude of interstore spillovers. The author addresses the estimation difficulties that(More)
Both distributed systems and multicore computers are difficult programming environments. Although the expert programmer may be able to tune distributed and multicore computers to achieve high performance, the non-expert may struggle to achieve a program that even functions correctly. We argue that high level abstractions are an effective way of making(More)
for many helpful suggestions regarding the research reported in this paper. He is grateful to Stanley Black and Maurizio Motolese for dedicated assistance in carrying out the computations. This paper is a drastic revision of Kurz [1997d]. Summary. We review the issues related to the formulation of endogenous uncertainty in rational belief equilibria(RBE).(More)
This paper explores the optimal income tax treatment of couples. Each couple is modelled as a single agent supplying labor along two dimensions: primary-earner and secondary-earner labor supply. We consider fully general nonlinear income tax schedules which creates a multi-dimensional screening problem. We prove that, under regularity and separability(More)
