This paper presents a model in which a technically inefficient firm is responsible for the emissions of pollutants. We derive second-best regulatory schemes (tax and quota) assuming that the firm’s technical efficiency is unknown to the regulator.  相似文献

Using discrete choice experiments we examine preferences for the spatial provision of local environmental improvements in the context of regeneration policies. Amenities we consider are: improvements to areas of open space, recreation facilities and other public spaces; street cleanliness; restoration of derelict properties; and the provision of paths dedicated to cycling and walking. We include the spatial scope of the policy as an attribute, making the trade-off between environmental amenity and its spatial provision explicit. We employ a novel estimator for average willingness to pay (WTP) for mixed logit models with a random cost coefficient, which is robust to the presence of price insensitive respondents and performs well relative to mixed logit estimation in WTP space. We find that the spatial scope of the policy affects both the intensity and heterogeneity of preferences, and that these effects are of statistical and economic significance.  相似文献

Internationalization of emerging market multinationals is a recent phenomenon gaining importance in the global economy. This foreign expansion of a new breed of companies has challenged established theories and practices in the field of international business (Cuervo-Cazurra, 2007). This article addresses the issue of whether or not there is something to learn from these emerging market companies and their foreign expansion. Focusing on the international trajectories of four Brazilian multinationals (i.e., Odebrecht, Embraer, Stefanini, and Marcopolo), this study analyzes their strategies and managerial processes during and after the recent economic crisis with regards to internationalization. Our qualitative fieldwork suggests that the trajectories of these Brazilian multinationals are quite unstructured and evolve as a reaction to the opportunities they face in international markets. It seems all four companies in our sample shared a strong entrepreneurial spirit and a high motivation to expand their international operations despite the crisis and the obstacles they faced. Our findings and suggestions in terms of lessons learned should provide valuable implications for multinational managers from other emerging markets by providing a better understanding of how Brazilian multinationals expand internationally, deal with economic crisis, and manage relationships with local and foreign institutions.  相似文献

A gravity model is developed to explain bilateral trade flows in primary and processed commodities within the same agri-food supply chain. It accounts for vertical production linkages, trade and domestic policies, and supply rigidities at the farm level. Our application focuses on cattle/beef trade flows between 42 countries. The estimated parameters of the model are used to simulate trade flows. We found large differences in the impacts of the full and partial liberalization scenarios. A parametric bootstrap procedure is used to generate confidence intervals around predicted trade liberalization outcomes.  相似文献

We consider a financial model with permanent price impact. Continuous-time trading dynamics are derived as the limit of discrete rebalancing policies. We then study the problem of superhedging a European option. Our main result is the derivation of a quasilinear pricing equation. It holds in the sense of viscosity solutions. When it admits a smooth solution, it provides a perfect hedging strategy.  相似文献

One novel implication of the open innovation paradigm is that inflows and outflows of knowledge are complementary. We argue that engaging simultaneously in buying and selling knowledge should allow firms to increase innovation outcomes. At the same time, we identify some of the relevant costs (cognitive, transaction, and organizational costs) that “open” firms can reduce by combining knowledge inflows and outflows. Empirically, however, we find no evidence for such complementarity in a sample of Belgian manufacturing firms. Firms buying and selling knowledge do increase their sales of new products, but at the same time their R&D costs increase more than proportionally. Our findings, therefore, indicate the need for research into a better understanding of the drivers of actual costs of organizing for open innovation. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

The consumer confidence index is a highly observed indicator among short-term analysts and news reporters and it is generally considered to convey some useful information about the short-term evolution of consumer expenditure. However, its usefulness in forecasting households consumption is sometimes questioned in empirical studies. A possible weakness can be due to the use of a linear functional form to model the relation between these two variables. Here, in order to overcome this issue, a non-parametric model is used, so that overly restrictive assumptions about the functional form can be avoided.  相似文献

Policy makers often see entrepreneurship as a panacea for inclusive growth in underdeveloped ‘Base of the Pyramid’ (BOP) regions, but it may also lead to unanticipated negative outcomes such as crime and social exclusion. Our objective is to improve the understanding of how entrepreneurship policies can lead to socially inclusive growth at the BOP. Drawing on data collected from Brazilian tourism destinations with varying entrepreneurship, innovation, and social inclusion policies, we argue that weak institutions coupled with alert entrepreneurs encourage destructive outcomes, especially if entrepreneurship policies are based solely on economic indicators. Policies addressing both economic and social perspectives may foster more productive entrepreneurial outcomes, albeit at a more constrained economic pace. The study extends the related BOP, entrepreneurship, global value chain, and sustainable tourism literatures by examining the poor as entrepreneurs, the role of local innovation, and how entrepreneurship policies generate different social impacts within poor communities.  相似文献
