It has been commonly observed that tropical countries tend to suffer from intense corruption and underdevelopment. This study provides an explanation for this long-standing disparity across the world based on variation in the intensity of ultraviolet radiation (UV-R). The central hypothesis is that UV-R is positively associated with the (historical) prevalence of eye diseases, which significantly shortens work-life expectancy as a skilled worker. This helps shape the worldwide distribution of corruption by affecting the incumbents' window of opportunity. Using data for up to 139 countries, I consistently find empirical support for the positive relationship between UV-R and corruption. The main findings withstand accounting for numerous alternative explanations for international differences in corruption levels. Employing individual-level data from the World Values Survey, I document suggestive evidence that exposure to UV-R is linked to surveyed respondents' tolerance towards corrupt activities. Furthermore, a subnational analysis for China lends credence to the cross-country evidence. 相似文献

ABSTRACTIn this study, we investigated whether the exchange rate and the interest rate had an effect on the inflation rate in the fragile five countries between the years of 1996Q4 and 2015Q4. In this context, a model was created to estimate the effect of interest rate and exchange rate on the inflation rate. The methods used in the study take into account cross-section dependence and heterogeneity. As a result of the analysis, it was determined that there was an exchange-rate and interest-rate pass-through effect in the fragile five countries. Moreover, it was found out that the cost channel and price puzzle were effective in Indonesia and South Africa but were not effective in Turkey, Brasil and India. 相似文献

We review a number of multi-population mortality models: variations of the Li & Lee model, and the common-age-effect (CAE) model of Kleinow. Model parameters are estimated using maximum likelihood. Although this introduces some challenging identifiability problems and complicates the estimation process it allows a fair comparison of the different models. We propose to solve these identifiability problems by applying two-dimensional constraints over the parameters. Using data from six countries, we compare and rank, both visually and numerically, the models’ fitting qualities and develop forecasting models that produce non-diverging, joint mortality rate scenarios. It is found that the CAE model fits best. But we also find that the Li and Lee model potentially suffers from robustness problems when calibrated using maximum likelihood. 相似文献

共同富裕是社会主义的本质要求,中国推动经济社会发展,归根结底是要实现全体人民共同富裕。新发展阶段下中国既要优化供需结构以加快构建新发展格局,又要改善分配结构以全面贯彻新发展理念,而供需结构优化与分配结构演化又是紧密关联的。本文建立了一个包含供给结构、需求结构和分配结构的多部门动态一般均衡模型,将分配结构演化分解到供给结构与需求结构转型上,提出了需求结构通过影响供给结构进而影响分配结构的理论机制。本文对近三十年全球四十余个经济体劳动收入份额和技能溢价的演化进行了发展核算,展示了中国分配结构演化的特征事实、供需动因与国际比较。研究发现,中国分配结构演化道路具有一定的特殊性:一方面,劳动收入份额转为上升,供给侧(需求侧)最主要的推动力是持续提高的劳动密集型产业(消费品)的劳动密集程度;另一方面,技能溢价不断扩大,供给侧(需求侧)最主要的推动力是持续提高的产业内部(消费品)的技能密集程度;供需结构转型在其中也发挥了重要作用。本文还基于历史趋势定量预测了未来中国分配结构的演化趋势,为实现2035年共同富裕目标提供了现实依据与政策参考。 相似文献

We estimate the impact of shipping cost on development for landlocked developing countries (LLDCs). Since container trade is important to them, we construct a country-specific measure of shipping cost, called HarpexCost, which combines the global cost of container shipping with information on how exposed to container shipping each LLDC is. We employ the common correlated effects (CCE) estimator of Pesaran (Econometrica, 2006; 55: 967) to first estimate the impact of HarpexCost on the LLDCs’ development, and then recover the actual impact of shipping cost from these estimates. Overall, we observe that shipping cost has large negative effects on the LLDCs. Building upon these results, we provide new estimates on the cost of landlockedness and how trade benefits their development. 相似文献

Alcoholic beverages represent both an important source of revenue and a driver of expenditure for provincial governments in Canada. As a result, the pricing of alcoholic beverages has substantial public policy implications. In this context, we re-examine existing work estimating the demand for three classes of alcoholic beverage (beer, wine, and spirits) by controlling for common correlated effects. The results reveal that any conclusions regarding the government’s ability to influence alcohol consumption is sensitive to the assumption that the relationship between the demand for alcoholic beverages and economic variables is identical across provinces. 相似文献

This study uses aggregated municipality data, for the years 2001–2009, to explore whether direct payments to farmers affect agricultural employment in Swedish municipalities. The decoupling reform in 2005 included a new grassland support payment accompanied by management obligations that had unexpectedly high redistributive consequences as it greatly increased common agricultural policy payments to municipalities with large areas of grassland. In some municipalities, total payments more than doubled. Thus, since the reform seems exogenous to the behaviour of farmers and the regional economy, the reform can be used to identify a subsidy effect. We find that a permanent increase in agricultural employment can be attributed to the new grassland support. Our results indicate that the grassland support generates an additional job at a cost of SEK 250,000, relative to the average agricultural wage of SEK 333,000. However, the subsidy effect is largely keeping jobs in agriculture, i.e. the grassland support may be slowing down the process of structural change in grassland regions. 相似文献
