Dutch disease occurs when currency strengthening associated with a booming sector of an economy crowds out a lagging trade‐dependent sector. In this study, a Keynesian‐style model is specified to deduce hypotheses about how increased foreign direct investment (FDI) aimed at Mongolia's mining sector affects its agricultural sector. A key finding is that while econometric results suggest the increased FDI strengthened Mongolia's currency, its adverse effect on Mongolia's trade‐sensitive agricultural sector is not sufficiently strong to cause the sector to decline. Although Dutch disease was not detected, the posited mechanism clearly is important. Specifically, when currency strengthening is ignored the reduced‐form elasticity of agricultural value‐added with respect to FDI is 2.7 times larger than when currency strengthening is taken into account (0.103 vs. 0.038). Also, FDI‐induced currency strengthening causes the Keynesian multiplier to drop from 2.40 to 2.00 and the FDI multiplier to drop from 3.05 to 1.89. 相似文献

In cross-national longitudinal studies it is often impossible to administer the same measurement instruments at the same occasions to all sample units in all participating countries. This quickly results in large quantities of missing data, due to (a) missing measurement instruments in some countries, (b) missing assessment waves within or across countries, (c) missing data for individual sample units. As compared to cross-sectional studies, the problem of missing values is further aggravated by the fact that missing values are always associated with different time intervals between repeated observations. In the past, this has often been dealt with by the use of phantom-variables, but this approach is limited to simple designs with few missing value patters. In the present paper we propose a new way to think of, and deal with, missing values in longitudinal studies. Instead of conceiving of a longitudinal study as a study with \(T\) discrete time points of which some are missing, we propose to conceive of a longitudinal study as a way to measure an underlying process that develops continuously over time, but is only observed at some selected discrete time points. This transforms the problem of missing values into a problem of unequal time intervals. After a quick introduction to the basic idea of continuous time modeling, we demonstrate how this approach provides a straightforward solution to missing measurement instruments in some countries, missing assessment waves within or across countries, and missing data for individual sample units. 相似文献

在界定全要素电力能源效率概念的基础上,构建了考虑环境因素的非径向全要素电力能源效率DEA模型。利用相关数据,从省际、区域两个层面对我国30个省(自治区、直辖市)的电力能源效率进行测度分析。结果显示:在全国30个省(自治区、直辖市)中,只有14个省区的电力能源效率是有效的,且这些省区不存在电力节能潜力;北京、天津、上海三大城市的平均电力能源效率最高,西部地区的该均值最低;我国省际电力能源效率存在显著的区域性差距,且4大区域的电力能源效率存在一定的梯度差距;对省区进行投入、产出调整,可使全国的电力消费量缩减6309.08亿千瓦小时。最后提出提高我国电力能源效率的政策建议。 相似文献

The business of business, not charity. Say eleemosynary its more confusing. Whatever, as long as we don't given 'em any cash. Harv Antione, ‘The Buzz Words of Entrepreneurship’ in Apocryphal Northern Tales This paper investigates the general determinants of corporate charitable donations in Canada and, in particular, the impact of imperfectly-competitive market structure. We utilize a profit-maximizing model and assume that charitable donations occur only if, by performing an advertising/public relations function, they increase revenue; or if, by acting as a fringe benefit, they result in a reduction in wage costs. In this context, because only firms in imperfect markets generate the rents from which donations can be made, we anticipate a positive relationship between donations and a measure of imperfect competition (concentration). The data is a cross-section sample of 38, 3- and 4-digit SIC manufacturing industries pooled for 1976 and 1981. The major findings are that: the results are generally compatible with the predictions of the model; concentration is a significant determinant of donations although non-linear; the cost of giving (the tax rate) is appropriately positive; and there are significant negative relationships for measures of foreign ownership and wage rates. 相似文献

从社会网络理论的强弱关系视角对2012-2014年福布斯中国富豪榜的企业家及其企业进行了政治关系的度量,检验了腐败是否会调节政治关系\"力量\"对企业价值的影响。研究发现,企业家本身所具有的政治关系对企业价值具有明显的正向影响作用,关系的\"力量\"越强,对企业价值的正向影响就越大;与此同时,腐败的出现会强化政治关系\"力量\"对民营企业价值的影响。通过分组验证发现,这种\"力量\"在腐败程度较高环境下更易对企业价值产生正向影响,但在腐败程度较低的环境中,政治关系对民营企业价值的影响很多时候并不显著。 相似文献

On one hand, Chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands.
On the other hand, they also have a bad reputation for buying counterfeit products. Their simultaneous preferences for two
contrasting types of product present a paradox that has not been addressed in the literature. This study attempts to present
an explanation of this paradox by examining the effects of traditional Chinese cultural values and consumer values on consumers’
deontological judgment of pirated CDs and the amount of social benefits they perceive they gain from them. We interviewed
300 Hong Kong Chinese consumers, and found that face consciousness increased materialism and risk aversion, thereby producing
a favorable deontological judgment of pirated CDs. Face consciousness also has a direct effect on the amount of social benefits
perceived in pirated CDs. Both favorable deontological judgment and perceived social benefits contributed to a strong intention
to buy pirated CDs. The results are discussed in a cultural perspective. 相似文献

This note acknowledges and corrects a programming error in our paper “Inequality of Opportunity in Brazil” (Review of Income and Wealth, 53(4), 585–618, 2007). Once the error is corrected, our bounds approach to the identification of individual model parameters in the presence of omitted variable biases is much less useful than indicated in the original paper. In the specific context of the measurement of inequality of opportunity, this implies that the decomposition of overall inequality of opportunity into direct and indirect effects is not reliable. However, the parametric approach introduced in our paper remains useful for obtaining a lower‐bound estimate of overall ex‐ante inequality of opportunity, as proposed by Ferreira and Gignoux (2011). 相似文献
