Models of firm microstructure are becoming now a standard building block in macroeconomics, trade, and development. This literature builds on the recognition that firm heterogeneity and the allocation of resources across firms plays a key role in determining aggregate productivity and the gains from trade. Barriers to the efficient allocation of resources across firms have been recently recognized to play a key role in economic development. This paper focuses on this methodological contribution, the link between firm microstructure and economic aggregates. 相似文献

We introduce a new panel data estimation technique for production and cost functions, the recursive thick frontier approach (RTFA). RTFA has two advantages over existing econometric frontier methods. First, technical inefficiency is allowed to be dependent on the explanatory variables of the frontier model. Secondly, RTFA does not hinge on distributional assumptions on the inefficiency component of the error term. We show by means of simulation experiments that RTFA outperforms the popular stochastic frontier approach and the ‘within’ ordinary least squares estimator for realistic parameterizations of a productivity model. Although RTFAs formal statistical properties are unknown, we argue, based on these simulation experiments, that RTFA is a useful complement to existing methods. 相似文献

This paper investigates the impact of international collaboration and its characteristics on the quality of the innovation of multinational enterprises (MNEs) in emerging markets. Using a unique dataset of 1428 international and comparable domestic collaboration projects over the 2010–2016 period, it finds that while international innovation collaborations are associated with high innovation quality, cultural distance has a negative effect on collaboration outcomes. Moreover, proximity to the focal firm's overseas R&D centres and the size of expenditure budgets play significant moderating roles in overcoming cultural barriers. Based on the RBV and dynamic capabilities theory, we investigate how firms from emerging markets can acquire these two crucial requisites for innovation. The characteristics of partners and intellectual property (IP) arrangements are also found to have a significant impact on the quality of innovations. 相似文献

This paper characterizes the relationship between entrepreneurial wealth and aggregate investment under adverse selection. Its main finding is that such a relationship need not be monotonic. In particular, three results emerge from the analysis: (i) pooling equilibria, in which investment is independent of entrepreneurial wealth, are more likely to arise when entrepreneurial wealth is relatively low; (ii) separating equilibria, in which investment is increasing in entrepreneurial wealth, are most likely to arise when entrepreneurial wealth is relatively high and; (iii) for a given interest rate, an increase in entrepreneurial wealth may generate a discontinuous fall in investment. 相似文献

In this paper, we follow the theoretical framework proposed by Djankov et al. (2003) to investigate the role of the state in resolving business disputes and its impact on enterprise performance. Using a survey of private enterprises in China, we first construct an index to quantify the power of the state vis-à-vis the market in resolving business disputes, and then find that enterprises located in regions where the government has a greater relative power enjoy better performance. Our results suggest that the regulatory state has played a positive role in the economic transition in China. 相似文献

This paper presents a strategic model of risk-taking behavior in contests. Formally, we analyze an n-player winner-take-all contest in which each player decides when to stop a privately observed Brownian motion with drift. A player whose process reaches zero has to stop. The player with the highest stopping point wins. Unlike the explicit cost for a higher stopping time in a war of attrition, here, higher stopping times are riskier, because players can go bankrupt. We derive a closed-form solution of a Nash equilibrium outcome. In equilibrium, highest expected losses occur at an intermediate negative value of the drift. 相似文献

Abstract Most multinational firms today operate multilateral production networks. Most existing empirical analyses, however, have focused on firms’ choice between producing at home and investing overseas. This paper uses detailed French multinational subsidiary data to examine the effect of existing production networks on multinationals’ entry decisions. The paper finds strong horizontal and vertical interdependence across multinationals’ foreign production locations, but little interdependence between home and foreign production when third‐country effects are taken into account. This result constitutes a sharp contrast to the conventional emphasis and highlights the importance of investigating foreign direct investment in the context of multinational production networks. 相似文献

Population aging has spurred developed countries around the world to reform their PAYG pension systems. In particular, delaying legal retirement ages and reducing the generosity of pension benefits have been widely implemented changes. This paper assesses the potential success of these policies in the case of the Spanish economy, and compares them with the results obtained by the (rather modest) reforms already implemented in 1997 and 2001. This evaluation is accomplished in a heterogeneous-agent dynamic general equilibrium model where individuals can adjust their retirement ages in response to changes to the pension rules. We check the ability of the model to reproduce the basic stylized facts of retirement behavior (particularly the pattern of early retirement induced by minimum pensions). The model is then used to explore the impact of pension reforms. We find that already implemented changes actually increase the implicit liabilities of the system. In contrast, delaying the legal retirement age and extending the averaging period in the pension formula to cover most of the individual's life-cycle can reduce the implicit liabilities substantially. These findings reveal the failure of the Spanish political system to distribute the costs of population aging more evenly across the generations. 相似文献

The relative majority rule and the unanimity rule are characterized in the two alternatives case. The main axioms rely on the idea of determining the preference of a group by partitioning it into two subgroups and aggregating next their preferences. 相似文献

We study collusion in an IPV auction with binary type spaces. Collusion is organized by a third party that can manipulate participation decisions. We characterize the optimal response of the seller to different threats of collusion among the bidders. We show that, contrary to the prevailing view that asymmetric information imposes transaction costs in side contracting, collusion in the optimal auction is efficient when the third party can implement monetary transfers as well as when it can implement monetary transfers and reallocations of the good. The threat of non-participation in the auction by a subset of bidders is crucial in constraining the seller's profit. 相似文献
