This note generalizes analytical relationships among activity variables of DEA models previously derived by Boussemart, Briec and Leleu (2007). We relax the asumption of constant returns to scale by showing that the key results hold under a weaker asumption of homogeneity. We use the notion of α -returns to scale to extend the analysis to strictly increasing and decreasing returns, covering now...

This paper employs a matched firm production-innovation panel dataset from Chile to explore the response of innovation increased competition arising China shock. The data cover wider range inputs and outputs than previously possible allow generating measures markups efficiency (TFPQ) that correspond closely concepts rents technological leadership envisaged in Schumpeterian literature. Except fo...

We quantify the importance of imperfect competition in US labor market by estimating size rents earned American firms and workers. construct a matched employer-employee panel dataset combining universe business worker tax records for period 2001–2015. Using this data, we identify estimate an equilibrium model with two-sided heterogeneity where workers view as substitutes because heterogeneous p...

This study examines the effect of labour market regulations on Greek tourism industry performance. The industry, steam engine economy, always drives to enhance efforts reach further savings in operating costs. However, that influence sector’s ability adjust costs have not been thoroughly investigated. We present a novel methodology permits evaluation technical and allocative efficiency one step...

This paper quantifies the contribution of technology gaps to international income inequality. I develop an endogenous growth model where cross-country differences in R&D efficiency and cross-industry innovation adoption opportunities together determine equilibrium gaps, trade patterns, Countries with higher are richer have comparative advantage more innovation-dependent industries. calibrat...

When firms collude and charge supracompetitive prices, consumers can bring antitrust lawsuits against the firms. litigation cost is low, accept as just another of doing business, whereas when high, lower price to deter litigation. Class action modeled a mechanism that allows plaintiffs attorneys obtain economies scale. We show class actions, firms’ incentive block them, may or not be socially d...

Firm-level, revenue-based productivity measures are ubiquitous in studies of firm dynamics and aggregate outcomes. One common measure is increasingly interpreted as reflecting “distortions” since distortions’ absence, equalization marginal revenue products should yield no dispersion this measure. Another but distinct the residual firm-level function, which reflects “fundamentals.” Using micro-l...

In parametric stochastic frontier models, the composed error is specified as the sum of a two-sided noise component and a one-sided inefficiency component, which is usually assumed to be half-normal, implying that the error distribution is skewed in one direction. In practice, however, estimation residuals may display skewness in the wrong direction. Model respecification or pulling a new sampl...

The "big-bang" liberalization of the inefficient Russian economy in 1992 provides a fruitful setting for analyzing the impact of several dimensions of market competition and other factors on enterprise efficiency. We analyze 1992-1998 panel data on 14,961 enterprises covering 75 percent of industrial employment, emphasizing the varied sources, geographic scope, intensity, time path, and surviva...

Agriculture is the focus of much contention in free trade negotiations. The Japanese government is against liberalizing the rice trade on the grounds that it would threaten “national food security” in the events of such shocks as crop failure, war, and embargo. Trade liberalization is expected to make Japan more dependent upon food imports and to make the Japanese economy more susceptible to th...
