Is environmental regulation bad for competition? A survey   总被引:1,自引:1,他引:0  
Theoretical and empirical research points to environmental regulation affecting the vigour of competition in product markets. We provide a critical, selective survey of that research. Environmental regulations can advantage large firms over small and raise concentration. They can discourage entry in their own right, and provide instruments with which incumbents can discourage entry strategically. They can provide the basis for predatory behavior by incumbents. Policy governance needs to be coordinated sufficiently to ensure that these secondary effects are accounted for in policy design. Cost-benefit evaluation of environmental policies that fail to account for likely detrimental impacts on product market competition will overstate the net benefits. This survey is a heavily-revised version of a discussion paper that the author wrote for presentation to a meeting of the OECD Competition Committee in June 2006 (OECD 2006). The support of OECD in the writing of that paper is gratefully acknowledged. Thanks also to Nick Johnstone, Jean-Phillipe Barde, Jeremy West, Sandeep Kapur, Michael Crew and an anonymous referee from this journal for helpful comments on earlier versions. All views expressed are those of the author alone.  相似文献

We investigate the welfare effects of eliminating business cycles in a model with substantial consumer heterogeneity. The heterogeneity arises from uninsurable and idiosyncratic uncertainty in preferences and employment status. We calibrate the model to match the distribution of wealth in U.S. data and features of transitions between employment and unemployment. In comparison with much of the literature, we find rather large effects. For our benchmark model, we find welfare effects that, on average across all consumers, are of a bit more than one order of magnitude larger than those computed by Lucas [Lucas Jr., R.E., 1987. Models of Business Cycles. Basil Blackwell, New York]. When we distinguish long- from short-term unemployment, long-term unemployment being distinguished by poor (and highly procyclical) employment prospects and low unemployment compensation, the average gain from eliminating cycles is as much as 1% in consumption equivalents. In addition, in both models, there are large differences across groups: very poor consumers gain a lot when cycles are removed (the long-term unemployed as much as around 30%), as do very rich consumers, whereas the majority of consumers—the “middle class”—sees much smaller gains from removing cycles. Inequality also rises substantially upon removing cycles.  相似文献

This paper presents a two-country DSGE model with state-dependent pricing as in Dotsey et al. [Dotsey, M., King, R.G., and Wolman, A.L., 1999. State-dependent pricing and the general equilibrium dynamics of money and output. Quarterly Journal of Economics 114, 655-690] and variable demand elasticity as in Kimball [Kimball, M.S., 1995. The quantitative analytics of the basis neomonetarist model. Journal of Money, Credit, and Banking 27, 1241-1277]. Following a domestic monetary expansion, the model predicts: (i) positive hump-shaped responses of domestic output and consumption, (ii) positive spillover effects on foreign output and consumption, (iii) a high international output correlation relative to consumption correlation, (iv) a delayed increase in domestic and foreign inflation, (v) a delayed nominal exchange rate overshooting, (vi) a deterioration in the terms of trade, and (vii) a J-curve in the trade balance. The model matches the impulse responses from an identified VAR more closely than an otherwise identical model with time-dependent pricing.  相似文献

Contemporary JIT literature provides evidence that the JIT philosophy has been extended to the selling function. The literature, however, lacks a concise definition of JIT-selling and reliable, valid scales for measuring the construct. A formal definition is proposed and JIT-selling scales are scientifically developed using survey data from manufacturers.  相似文献

This exploratory study identifies actions and behaviors that subordinates attribute to bad leadership and explores the implications these factors have for organizations. Data were obtained through a Web‐based survey that generated 335 respondents who completed at least some of the questions. Results identified the prevalence of bad leaders, behaviors causing a leader to be perceived as bad, the impact of bad leaders on the employee and organization, whether these bad leaders had always been bad, and what happened to the bad leader. An interesting discovery was that the majority of bad leaders were either promoted or rewarded by the organization.  相似文献

Previous research has shown that salesperson burnout affects sales productivity, employee retention, and job satisfaction. Although burnout has often been conceptualized as a multiple‐component construct, research typically has approached the efficacy of burnout reduction techniques by using overall measures of burnout rather than by examining the effects of such techniques on individual burnout components. The present research investigates how social support and choice of coping strategy relate to burnout components, illustrating the need to consider such components when conducting burnout‐related research. © 2000 John Wiley & Sons, Inc.  相似文献

Many goods are marketed after first stating a list price, with the expectation that the eventual sales price will differ. In this article, we first present a simple model of search behavior that includes the seller setting a list price. Holding constant the mean of the buyers’ distribution of potential offers for a good, we assume that the greater the list price, the slower the arrival rate of offers but the greater is the maximal offer. This trade‐off determines the optimal list price, which is set simultaneously with the seller's reservation price. Comparative statics are derived through a set of numerical sensitivity tests, where we show that the greater the variance of the distribution of buyers’ potential offers, the greater is the ratio of the list price to expected sales price. Thus, sellers of atypical goods will tend to set a relatively high list price compared with standard goods. We test this hypothesis using data from the Columbus, Ohio, housing market and find substantial support. We also find empirical support for another hypothesis of the model: atypical dwellings take longer to sell.  相似文献

This study offers a "best evidence" approach to summarizing recent benefit-cost analyses of international agricultural research in Africa. First, from an extensive literature review and the resulting global inventory of impact studies, 23 studies are identified that calculate aggregate rates of return for Consultative Group on International Agricultural Research (CGIAR) and partner investments in Sub-Saharan Africa (SSA). These studies are then appraised against a review framework consisting of principles, criteria, and indicators for study rigor. Subsequently, the economic benefits reported by studies grouped on the basis of its analytical rigor are aggregated and set against total investment by the CGIAR and national agricultural research systems to determine if the total investment to date can be justified by documented benefits under a range of assumptions. As a result, the study finds that aggregate investment is justified under a fairly wide range of suppositions. Under all scenarios, the vast majority of documented benefits stem from a relatively limited array of activities with a majority of benefits stemming from biological control (80%). Close to 20% of total benefits result from crop genetic improvement, and less than 1% result from all other activities. The implications of these results for research investment strategies in SSA and impact assessment are discussed.  相似文献

This study examines the supply response of the Greek beef market and the possible effect of the European Union’s Common Agricultural Policy (CAP) on the Greek beef sector during the period 1993–2005. A Generalized Autoregressive Conditional Heteroskedasticity (GARCH) process is used to estimate expected price, and price volatility, while several different symmetric, asymmetric and non-linear GARCH models are estimated. The empirical results show that price volatility and feed price are important risk factors in the supply response function, while the negative asymmetric price volatility that was detected implies that producers have a weak market position. Furthermore, the empirical findings confirm that the annual premium paid by the EU to beef producers had a positive impact on the production level and also, the change of the EU price support regime, after 2006, is having negative effects on beef production level in Greece.  相似文献
