Outsourcing, Imports and Labour Demand 总被引:7,自引:0,他引:7
This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

The availability of a stochastic repairable system depends on the failure behaviour and on repair strategies. In this paper,
we deal with a general repair model for a system using auxiliary counting processes and corresponding intensities which include
various degrees of repair (between minimal repair and perfect repair). For determining the model parameters we need estimators
depending on failure times and repair times: maximum likelihood (ML) estimator and Bayes estimators are considered. Special
results are obtained by the use of Weibull-type intensities and random observation times. 相似文献

A theory of reciprocity 总被引:29,自引:4,他引:29
People are reciprocal if they reward kind actions and punish unkind ones. In this paper we present a formal theory of reciprocity. It takes into account that people evaluate the kindness of an action not only by its consequences but also by its underlying intention. The theory is in line with the relevant stylized facts of a wide range of experimental games, such as the ultimatum game, the gift-exchange game, a reduced best-shot game, the dictator game, the prisoner's dilemma, and public goods games. Furthermore, it predicts that identical consequences trigger different reciprocal responses in different environments. Finally, the theory explains why outcomes tend to be fair in bilateral interactions whereas extremely unfair distributions may arise in competitive markets. 相似文献

This paper investigates to what extent individuals' risk preferences are correlated with the cross-sectional earnings risk of their occupation. We exploit data from the German Socio-Economic Panel, which contains a direct survey question about willingness to take risks that has been shown to be a behaviorally valid measure of risk aversion. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital variables in Mincerian wage regressions. Our evidence shows that individuals with low willingness to take risks are more likely to work in occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience. 相似文献

Many medium-size cities suffer from severe traffic congestion and poor accessibility, limiting their potential to improve their economy, environment, and social equity. These problems could be addressed by creating high-quality transit linking such cities with suburban and other catchment areas through use of existing rail lines and abandoned former railway alignments. This concept, termed ‘Swift Rail’, would call for an innovative approach to local railway and transport development. 相似文献

Wildlife tourism experiences have the potential to positively impact tourists’ awareness, appreciation and actions in relation to the specific wildlife they encounter and the environment in general. This paper investigates the extent of such impact across multiple sites, and uses Structural Equation Modelling to identify factors that best predict positive long-term learning and environmental behaviour change outcomes. Three sets of variables were measured – visitors’ entering attributes (including pre-visit environmental orientation and motivation for the visit), salient aspects of the experience, and short- and long-term learning and environmental behaviour change outcomes. Although attributes such as pre-visit commitment and motivation to learn were among the best predictors of the long-term impact of the experience, there was evidence that aspects of the experience were also important. In particular, reflective engagement which involved cognitive and affective processing of the experience was found to be associated with short- and long-term environmental learning outcomes. The implications for wildlife tourism managers are discussed. 相似文献

When financial statements are audited, a client and auditor may disagree about an accounting disclosure. While the disclosure of such a disagreement may increase the information content of a statement it may also be socially undesirable in that it signals a difference in views about the state of the reporting enterprise. This in turn may increase agency costs and introduce uncertainty about the state of the firm. In this paper we focus on public policy implications concerning auditor-client disagreements and examine the ex ante probability that such cases will occur. We find that accounting standards that allow two accounting options may be optimal in reducing frequency of disagreements among auditors and between standard-setters and their constituencies, and possibly also between clients and their auditors. The New Zealand model of compliance with accounting standards may be preferable to that practiced in the US. 相似文献

This paper compares the efficiency of large ski resort conglomerates with independent ski resorts using data on four countries (Canada, France, United States, Switzerland). Using the stochastic frontier production approach, I find that ski resorts that are owned and managed by the Intrawest group are significantly more efficient than independent ski resorts. The efficiency gap is about nine percentage points on average. The remaining ski resort conglomerates (American Skiing, Vail Resorts Inc., and Compagnie des Alpes SA) do not operate more efficiently than independent ski resorts.

Abstract . For more than a generation, contemporary mainland Chinese have lived under first a military dictatorship and now a political party dictatorship. How to explain to an eager Chinese academic audience what the American dream of ‘liberty and justice for all’—realized only in part in some areas but approached progressively nearer in others—really means? The U.S. has predominantly a capitalist system but its people are committed to equality of opportunity. It tempers ‘rugged individualism’ by concern for the poor, the handicapped and the unfortunate. It has many serious economic, social and cultural problems but its citizens, drawn from most of the peoples of the world—not the special interest groups trying to benefit at the expense of others—are determined to solve them equitably and rationally. The trade and budget deficits are related to government instrumentalities. 相似文献

This paper provides empirical evidence on the link between different external knowledge sourcing strategies from universities and firms’ innovation output measured by the number of patent applications. Three strategies for acquiring external knowledge are distinguished: buying, cooperating and contracting out. The empirical model is based on the instrumental variable version of the ordered probit model. Geographical distance to local universities is employed as an instrument for the different knowledge sourcing strategies. The empirical results show that buying knowledge from universities is significantly positively related to the number of patent applications, while cooperating with universities and contracting out does not have an impact. This also holds for buying knowledge from domestic universities. 相似文献
