This paper utilizes the instrumental variable threshold regressions approach to reassess the trade–development link. It finds evidence that trade openness contributes to uneven development. Greater trade openness tends to have beneficial effects on real development of high‐income countries. For low‐income ones, however, trade openness appears to influence real income in a significant and negative way. The data also reveal that greater trade openness has a positive effect on capital accumulation, productivity growth, and financial development in high‐income countries, but a negative impact in low‐income ones. 相似文献

We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage formation at the most disaggregate level – the workplace. Using linked employer?employee data, we find that an increased use of low‐skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant share using both fixed effects and instrumental variables. 相似文献

When agents have different needs for a public facility but serving a given agent allows serving all agents with smaller needs than his without any extra cost, how should the agents divide the cost of the facility among themselves? We provide a strategic implementation of the Shapley value for this class of cost‐sharing problems. We introduce a three‐stage extensive form game that respects individual rationality and show that there is one and only one subgame‐perfect equilibrium outcome of the game. Moreover, it is the allocation assigned by the Shapley value. 相似文献

This article analyzes variations in line‐of‐business diversification status and extent among property–liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line‐of‐business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers. 相似文献

Leadership programs in public health have been declining in numbers since 2012. The decline in training programs could be due to the lack of outcome‐based results and the lack of a manageable set of standardized skills needed for public health leadership. A comprehensive study was completed in two phases to determine if the current model of public health leadership institutes is effective at generating outcome‐based results. The following paper will focus on the first phase of the study. The first phase included a qualitative analysis to determine the domains, definitions, and skills needed to lead. An analysis of the skills, domains, definitions, and traits included in five established and commonly used leadership models/theories in public health leadership development (Transformational, Servant, Appreciative, Collaborative, and Emotional Intelligence leadership) plus the National Public Health Leadership Development Network (NLN) Leadership for Community Health, Safety & Resilience Competency Framework was completed. Of the 161 different skills, definitions, traits, and/or competencies from the five leadership models and the NLN competency framework, 123 were determined to be related to one of six domains needed for leadership and were defined into 21 skills. The findings could lead to more uniformity in public health leadership development and evaluation. 相似文献

A moneyness‐based propensity to sell (MPS) measure, at the aggregate level, determines the propensity of option holders to exercise their winning relative to losing positions. Using data on individual stock and S&P 500 Index options, we find that the MPS measure has significant predictive power over the cross section of delta‐hedged option returns. We test the disposition effect in the options market based on a long–short strategy that exploits price distortions induced by the disposition bias. More pronounced evidence of the disposition bias is found for individual at‐the‐money call options than put options where the significance of abnormal returns remains robust across different subsamples even after we control for the portfolio option greeks and market‐based risk factors. The profitability of the long–short strategy is related to limit‐to‐arbitrage proxies suggesting that behavioral explanations help explain the positive relation between the MPS measure and delta‐hedged option returns. 相似文献

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation. 相似文献

This paper generalizes Rubinstein and Wolinsky's (1987) model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency, and dynamics. In the benchmark model, equilibrium exists uniquely and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates if and only if middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic activity. This is novel, compared to the original Rubinstein–Wolinsky model, where equilibrium is always efficient. 相似文献

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
