We show that in multi-sector optimal growth models, where the technology satisfies a simple reachability condition, infinite horizon programs which satisfy the competitive conditions are optimal. We provide examples of a variety of production models where the reachability condition is satisfied....

I consider a situation in which workers have present-biased preferences and tend to procrastinate their tasks, but underestimate the degree of self-control prob- lems that they will face in the future. Brocas and Carrillo (2001) show that a form of competition always mitigates delay in a setting...

We test the hypothesis that strategic interactions foster overconfidence. We experimentally compare an environment where players have an incentive to overstate their own ability to deter competitors, with one where this incentive is removed. We find that overconfidence persists in the former...

This paper studies the impact of product market competition on the well-documented positive relation between firms' current profitability and future stock returns. I find that this relation is robust only in competitive industries. A long-short portfolio sorted on profitability earns an average...

This note reviews May 2019 OECD framework agreement report, “OECD/G20 Inclusive Framework on BEPS: Progress Report July 2018-May 2019” on international taxation of the ‘digital economy'. The core conclusions of the review are:1. The framework agreement proposals to-date represent complex,...

We develop a multi-industry growth model with oligopolistic competition, endogenous entry and variable markups. At the heart of our model is a complementarity between capital accumulation and competition, which may give rise to multiple steady-states – steady-states characterized by high...

We highlight the impact of capital quality, i.e., the depreciation rate of capital assets, on firms' investment behavior, endogenous output price dynamics, and industry equilibrium outcomes. To rigorously examine this question, a continuous-time model of dynamic capacity investment under...

This paper studies the impacts of the interactions between the changing macroeconomic conditions and the nature of competition on firms' investment timing decisions. With a model featuring business-cycle variations in both the profit level and the expected growth rate and volatility of the...

Competition in the U.S. appears to have declined. One contributing factor may have been heterogeneity in the availability of credit during the financial crisis. I examine the impact of product market peer credit constraints on long-run competitive outcomes and behavior among non-financial firms....
