This paper considers the measurement of firm’s specific (in)efficiency while allows for the possible heterogeneous technologies adopted by different firms. A flexible stochastic frontier model with random coefficients is proposed to distinguish technical inefficiency from technological differences across firms. Posterior inference of the model is made possible via the simulation-based approach,...

This paper addresses how financial development affects product quality and firmlevel exports depending on the firm’s productivity. To this goal, I propose a heterogeneous firms model with endogenous quality, credit constraints and heterogeneous productivity of a firm. I show theoretically and confirm empirically that lower financial constraints result in higher-quality output and higher exports...

The aims of this paper are twofold. The first is to analyse the interaction between research and development (R&D) activities of firms and heterogeneous consumer preferences in structuring the evolution of an industry. The second is to explore the heterogeneity in firms’ innovation strategies. Is heterogeneity sustainable in the long-term and what happens to the market shares of firms having di...

Why do large firms choose to compete with a cartel rather than to cooperate? Bos and Harrington (2010) explained why small firms do not join in a cartel by introducing heterogeneous firms. But it is still unclear why large firms do not join in a cartel. This paper shows a possibility that only mid-level productive firms benefit from joining a cartel by considering endogenous choices of firm-pro...

This study examines the costs and benefits of uniform accounting regulation in the presence of heterogeneous firms that can lobby the regulator. A commitment to uniform regulation reduces economic distortions caused by lobbying by creating a free-rider problem between lobbying firms at the cost of forcing the same treatment on heterogeneous firms. Resolving this tradeoff, an institutional commi...

This paper develops an idea flows theory of trade and growth with heterogeneous firms. New firms learn from incumbent firms, but the diffusion technology ensures entrants learn not only from frontier technologies, but from the entire technology distribution. By shifting the productivity distribution upwards, selection on productivity causes technology diffusion and this complementarity generate...

[Abstract] In this paper we investigate within-firm wage inequality across heterogeneous industries that hold different positions in the domestic value chain, and across heterogeneous firms that have different exposure to trade. We find that the wage inequality problem is more severe in upstream industries than in downstream ones, and among firms with greater exposure to trade (i.e., larger exp...

The aims of this paper are twofold. The first is to analyse the interaction between research and development (R&D) activities of firms and heterogeneous consumer preferences in structuring the evolution of an industry. The second is to explore the effects of patent life and patent breadth on market outcomes. To answer these research questions, an evolutionary, multi-agent based, sectorlevel cum...
