Empirical Tests of the Pollution Haven Hypothesis When Environmental Regulation is Endogenous

The pollution haven hypothesis (PHH) posits that production within polluting industries will shift to locations with lax environmental regulation. While straightforward, the existing empirical literature is inconclusive owing to two shortcomings. First, unobserved heterogeneity and measurement error are typically ignored due to the lack of a credible, traditional instrumental variable for regulation. Second, geographic spillovers have not been adequately incorporated into tests of the PHH. We overcome these issues utilizing two novel identification strategies within a model incorporating spillovers. Using US state‐level data, own environmental regulation negatively impacts inbound foreign direct investment. Moreover, endogeneity is both statistically and economically relevant.

On the importance of matching strategic behavior and target market selection to business strategy in high-tech markets

Business strategy is fundamentally concerned with the actions required to create superior customer value in the firm’s target markets with the ultimate goal of achieving superior performance. Marketing theory suggests that two critical marketing activities required to achieve this end are: (1) the adoption of appropriate strategic behaviors (i.e., customer-oriented, competitor-oriented, technology-oriented) and (2) targeting of the appropriate market segments (i.e., innovators, early adopters, early majority, late majority, laggards). This study builds on prior research which demonstrates that the strategic behavior—firm performance relationship is contingent on the firm’s strategy by examining this relationship in high tech markets and by considering the incremental contribution of appropriate target market selection. Responses from 160 senior marketing managers in high-tech firms reveal strong support for our framework. Thus, this study provides useful guidance to executives and managers in high-tech firms regarding the steps that they should take to increase their probability of success.

Manufacturing as a system-determined science

This paper addresses the general issue of manufacturing as a system-determined science. To adequately assess the degree to which systems thinking enters into considerations of modern manufacturing, several interconnected schemes are developed which, taken together, provide a taxonomy of manufacturing problems. It is shown that each manufacturing problem exists at a certain hierarchical level, the lowest being Raw Materials, the highest Values. Further, each problem can be labeled as a Design, Production, or Distribution problem, provided these terms are taken in a general sense. Finally, it is shown that each problem has associated with it one or more foundational system concepts (flexibility, complexity, adaptation, etc.), lending the problem its characteristic system flavor. Putting the hierarchical, Design-Production-Distribution and system concepts labels together supplies the basis for a classification scheme which, at the same time, enables us to unequivocally answer the question as to whether there is a significant systems component to most problems of modern manufacturing. There is!

基于规模和位序差异的陕西入境旅游研究

为科学、准确研究陕西入境旅游发展的区域差异,文章借鉴研究区域经济规模和位序差异的成熟方法,选取2001--2010年国家和陕西省统计年鉴中陕西省7个重点城市的相关数据（2003年由于非典原因除外）,对陕西入境旅游的区域差异进行了研究。发现陕西入境旅游业发展空间差异较大,但有逐渐缩小的趋势,7个重点城市入境旅游发展不平衡且不平衡格局相对稳定等问题。在此基础上,分析了影响陕西入境旅游规模位序差异化的原因。     

Modern rice technology and regional wage differentials in the Philippines

Fear has been widely expressed that the modern rice varieties have created large disparities in regional income distribution, as the productivity gap between favorable and unfavorable rice-production environments widened due to differential technology adoption throughout South and Southeast Asia over the last two decades. Technology affects the income of farm population directly through its effects on productivity and factor use, and indirectly through its effect on factor prices. In particular, the ultimate distributional impact of modern varieties will critically depend on the interregional labor-market adjustments through migration in response to regional wage differentials created by the differential technology adoption, since labor is the main resource of the majority of the rural population. We studied favorable and unfavorable rice-growing villages in the Philippines, and found that adoption of modern varieties during the 1970s was positively related to population growth rate. Contrary to popular belief, no association was observed between wage rates and adoption of modern varieties as of 1986. These findings support the hypothesis that the differential adoption of modern rice varieties induced interregional labor migration toward equalization of wage income across different production environments.     

Predictive performance of the World Bank's commodity price projections

The World Bank's commodity price projections are widely used for various planning purposes. Two aspects of the Bank's projections of relative prices are studied in this paper. The first is whether the forecasts make efficient use of the information available at the time the forecast is made. The second is whether the forecasts predict future prices with greater accuracy than alternative forecasting methods. These matters are studied by comparing the World Bank's past price projections with the actual prices that were subsequently observed. The results show that, overall, the World Bank forecasts do not pass either test. First, the World Bank forecasts are informationally inefficient. Prediction error (projection minus actual price) tends to be positively correlated with the projections themselves. Although the direction of future price movements tends to be correctly predicted, the magnitude of these movements tends to be overpredicted. Second, the World Bank forecasts do not perform well even compared with the simplest of alternative forecasting methods - the prediction of no change.     

Estimating Technical Efficiency and Production Risk under Contract Farming: A Bayesian Estimation and Stochastic Dominance Methodology

We investigate production risk, technical efficiency and risk attitudes amongst contract and independent farmers. We use a Bayesian parametric approach and stochastic dominance quantile regression methods to compare technical efficiency and risk attitude of smallholders in Nepal. Using farm‐level data, we find that contract farmers appear to show lower inefficiency and lower production risk. Additionally, contract and independent farmers can increase output by reducing the scale of operation. Regardless of the commodity produced and farming arrangement (contract or independent production), we find that labour, land and other inputs are risk‐augmenting, while the role of capital is mixed. We find a second order stochastic dominance (SSD) for lentils, and first order stochastic dominance (FSD) for tomatoes, ginger and HYV paddy seed commodities. Finally, contract farmers are more risk averse than independent farmers, regardless of the commodity produced.     

Food fraud: economic insights into the dark side of incentives

In this review, we contextualise the articles in this special issue, relating them to existing food fraud research, and identify food fraud research trends, challenges and priorities for the near term. We accomplish these aims through a comprehensive review of research by food scientists, economists, other social scientists, legal experts, government research groups and international trade organisations. Existing food fraud research is heavily weighted towards food science, packaging and labelling, and legal areas of knowledge discovery. Moving forward, research is needed pertaining to general economic welfare outcomes from food fraud incidences, economic incentives to deter frauds, economic spillovers from fraud incidences to other food products and markets (domestic and international) and further delineation of the effect of different types of food fraud on consumer and producer welfare. The articles in this special issue make significant contributions to understanding of the role of food fraud in consumer decisions, measuring consumer welfare losses from fraud, food fraud spillover effects to other markets and new frameworks for fraud analysis.
