It is standard in the literature on training to use wages as a sufficient statistic for productivity. This paper examines the effects of work‐related training on direct measures of productivity. Using a new panel of British industries 1983–96 and a variety of estimation techniques we find that work‐related training is associated with significantly higher productivity. A 1% point increase in training is associated with an increase in value added per hour of about 0.6% and an increase in hourly wages of about 0.3%. We also show evidence using individual‐level data sets that is suggestive of training externalities. 相似文献

认为做到完善维修没有一个现成的标准。只有根据资产效率优化(AEO)的基本概念,生成符合客户实际需求的特定模型,才能更好地进行资产(维修)管理。而这个管理过程,SKF是通过一个基于互联网的被称之为客户需求分析(CNA)的软件工具来实现的。本文也给出了应用此工具时的一些成功数据。 相似文献

This paper uses a computable general equilibrium model to assess the effects of the Uruguay Round (UR) and CAP reform. Detailed attention is given to the impact of the agricultural components of the UR and of the CAP reform on the agricultural and food-processing sectors of the EU. The CGE model used, while based on the standard Global Trade Analysis Project (GTAP) model, uses a more detailed representation of the UR and CAP policy changes than is usual in GTAP analyses of the UR effects. In so doing it assumes a degree of specificity of factors used in agriculture and makes appropriate agricultural policy variables endogenous. Finally, it assesses the consequences of assuming imperfect competition in all non-agricultural sectors. 相似文献

This paper presents a typology that distinguishes two types of flexible organizations based on the clarity of purpose and the extensiveness of formal rules. The analysis shows that these forms of flexibility are related to whether organizations engage with their environments reactively or strategically. One form (strategic flexibility) is evident in a 'goal-directed' type of organization (having clear goals but low levels of formal rules), and the other can be observed in an informally-organized type (lacking clear goals, and with limited formal rules). These are compared with two other types: formally-organized (clear goals and extensive formal rules); and rule-governed (lacking clear goals, extensive formal rules). An analysis of a sample of fifty organizations shows clear differences between the four types with respect to contextual factors; environmental conditions; strategy and structure; and integrative mechanisms. 相似文献

Many publications, that treated with Portfolio Management, were devastating for all asset allocation models in the context of portfolios. The elimination of extreme events (asymmetric or tail dependence) during the portfolio construction process can reduce the skills of asset managers to reduce risk through diversification. The copula theory allows us to calculate an alternative to measure the dependence of extreme events in assets through the index lower tail dependence. We check that the strategies with tail dependence overcame Talmud rule, the Markowitz model and the model of Tu and Zhou by simulating 1,000 portfolios with 3, 5, 10 and 20 randomly selected assets from DJIA for the period 03/1990 until 12/2016. We conclude that models of tail dependence and Markowitz had more performance ex-ante than Talmud and the Tu and Zhou model for portfolios with 3, 5, 10 and 20 assets. Tail dependence models overcome Markowitz, in terms of cumulative return, in over 60% of months considered in the analysis. The results indicate that the Talmud rule should be discarded in a context of constructing portfolios with individual stocks ahead strategies with tail dependence. 相似文献

It is well known that government plays an important role in the business activities of Chinese firms. Less certain is the effect this influence has on the wealth of those firms’ shareholders. We contribute to the literature by analysing stock market reactions to announcements by Chinese firms of overseas mergers and acquisitions (OMAs). OMAs are of particular interest because there can exist a conflict between the interests of the public sector in acquiring overseas assets, and the interests of the private sector in maximizing shareholder wealth. Our main dataset consists of 213 observations of 157 OMA events that occurred between 1994 and 2009, using share market returns from the Shanghai, Shenzhen, Hong Kong and US markets. The aggregation of share price data across multiple markets, and the listing of firms in multiple exchanges, raise econometric issues for the standard event‐study methodology. To address these, we use a new, feasible generalized least squares (GLS) procedure developed by Gu and Reed (2012) . On the basis of an analysis using both aggregated and disaggregated samples, and of daily and cumulative abnormal returns, we find consistent evidence that (i) Chinese OMAs have not lowered the wealth of shareholders of Chinese acquiring firms, and (ii) shareholders of Chinese acquiring firms have not fared worse under under China's ‘Go Global’ policy of encouraging outward investment by Chinese firms. 相似文献

This study empirically examines the relationship between free trade agreements (FTAs) and greenhouse gas (GHG) emissions. For this purpose, we use three different FTAs: the Southern Common Market, the North American Free Trade Agreement, and the Australia–United States Free Trade Agreement. These FTAs are between developing, both developing and developed, and only developed countries, respectively. Panel unit root, panel cointegration, and fully modified ordinary least squares estimations are employed to examine the long‐run relationship between GHG emissions and trade liberalization. The results indicate that the environmental effects of FTAs depend on the different agreement types. When FTAs are between only developed or developing countries, overall there is no environmental damage, and these types of FTAs can be beneficial for the environmental quality in the long run. However, when developing and developed countries are in a trade agreement, overall environmental quality decreases due to increased GHG emissions. 相似文献

In this study, we are concerned with the resources that are brought to joint ventures, and whether or not the way in which those resources are combined can improve parent‐firm performance. We are also interested in whether or not the exposure of valuable resources through the permeable membrane of the joint venture can have an adverse effect on performance. These questions are explored using a sample of 74 domestic, dyadic joint ventures, and our findings suggest that the strategy can have zero‐sum and positive‐sum outcomes.
