Labour economists typically assume that pay differences between occupations can be explained with variations in productivity. The empirical evidence on the validity of this assumption is surprisingly thin and subject to various potential biases. The authors use matched employer-employee panel data from Belgium for the years 1999–2006 to examine occupational productivity-wage gaps. They find that occupations play distinct roles for remuneration and productivity: while the estimations indicate a significant upward-sloping occupational wage-profile, the hypothesis of a flat productivity-profile cannot be rejected. The corresponding pattern of over- and underpayment stands up to a series of robustness tests.  相似文献

This article aims to evaluate the production line automation projects developed by Brazilian and Colombian companies from the Project Management perspective, through the analysis of the application degree of PMBOK processes, to understand how formal techniques are being employed in these countries and also to identify improvement opportunities, when necessary. Data were collected through a survey. The similarity index between the ten processes, with the highest application degree in the Brazilian and Colombian samples, was 70%. For the processes with the lowest application degree, the similarity index was 60%. No similar study was found in the literature.  相似文献

The aim of this paper is to show that inequalities of wealth can be necessary conditions to explain the apparition and rise of a capitalistic system. We try to highlight Marx's insights on primitive accumulation. Our dynamic framework is consistent with Roemer's idea of endogenous class stratification. We extend this calculation by incorporating some features of the Pasinetti–Samuelson–Modigliani model, and provide an example of possible microfoundations.  相似文献

This paper is concerned with the study of insurance related derivatives on financial markets that are based on nontradable underlyings, but are correlated with tradable assets. We calculate exponential utility‐based indifference prices, and corresponding derivative hedges. We use the fact that they can be represented in terms of solutions of forward‐backward stochastic differential equations (FBSDE) with quadratic growth generators. We derive the Markov property of such FBSDE and generalize results on the differentiability relative to the initial value of their forward components. In this case the optimal hedge can be represented by the price gradient multiplied with the correlation coefficient. This way we obtain a generalization of the classical “delta hedge” in complete markets.  相似文献

This study provides some estimates of the magnitude of the subsidies extracted by S&L holding companies under the present flat-rate deposit insurance system. The results suggest that the flat-rate deposit insurance system induces substantially uneven and inequitable distribution of subsidies among thrift institutions. The analysis of the thrift institutions' asset volatilities over the 1966–1988 period does not support the claim that deregulation of the industry has led to a systematic increase in risk-taking in the industry. On the other hand, we find that a large fraction of the asset volatilities are attributable to firm-specific investment policies and that the risk of the institutions' assets change considerably over time. Taken as a whole, the results suggest that switching to a risk-based deposit insurance system would be economically more efficient than the present scheme. We provide some recommendations for policy changes that can increase the efficacy of risk-based insurance by increasing the level of monitoring by depositors and the financial markets.  相似文献

This paper has two objectives. The first is the documentation of the relative importance of the largest financial groups in the world. The list of top 50 financial groups ranked by total assets in 2003 is compared to a similar list available for 1986. The second objective is to examine where financial firms are expanding their operations and to document some of the factors that may explain the most-favoured locations of these financial groups.The results of this study have two important implications. First, they indicate that location-specific advantages such as size, human capital and cultural distance, do provide an explication of the internationalization of financial firms. Second, they show that good governance has a strong impact on the choice of countries by firms.  相似文献

Advertisements often display ideal female bodies which create unattainable standards of beauty, generating body anxiety and disorders in female viewers. Accordingly, public health concerns would encourage the use of natural, unedited models in advertisements. However, the advertising performance of natural models remains contentious. We argue that previous inconsistent findings about this performance may result from a complex causal framework in which natural models impact performance through two affective mediators (body anxiety, and repulsion toward the model), while allowing moderation by the viewer's own body mass index (BMI). Data collected in a nationally representative sample of 400 young women largely (but not entirely) validate this causal framework. Natural models triggered repulsion in viewers with higher BMI, which hurt advertising performance. Body anxiety, however, was positively correlated with advertising performance, and did not mediate any effect of natural models.  相似文献

This study compares the performance of new businesses owned by recent immigrants with that of other new firms. It addresses an on-going unresolved discussion in the academic and professional literatures by drawing on a large sample of Canadian business owners whose firms began trading between 2000 and 2004 and using taxation data to track 2004 to 2008 performance. The results provide empirical evidence that young immigrant-owned exporter firms outperformed young domestically-founded firms whether or not they exported; however, immigrant-owned young enterprises that did not export underperformed other young firms. Owner-level factors such as gender, growth intentions and experience also influenced growth performance among young SMEs. The results provide evidence that suggests that immigrants have resources such as access to international networks that provide competitive advantage over non-immigrant owners that export or aspire to export. Not all immigrant business owners, however, are able to lever such advantages. The implications of the findings for research and policy are discussed.  相似文献

Classical portfolio theory informs investors that they should have a large number of assets in their portfolios in order to diversify risk. We show that the non-Gaussian features of stock return distribution may not allow for this risk protection in times of crisis. Moreover, we demonstrate empirically that, if investors are risk-averse and consider higher order moments, they have numerous incentives not to diversify their portfolios fully. This is caused by the evolution of both large losses and asymmetry of returns when the numbers of assets in a portfolio change.  相似文献

  • The topic of donations is one of high relevance and has been widely covered in contemporary marketing literature. It is a topic of interest to both theoreticians and practitioners alike, particularly due to its implicit links to fundraising activities and research. The reality of what makes an individual donor ultimately part with his money and give it away to a nonprofit organization is a hot contemporary topic. This study looks into the role of religiosity as a predictor of donations practices. Also volunteerism and compassion, two acts of pro‐social behaviour are analysed as predictors of donations practices. Using data collected from a survey of 612 charity donors in Portugal, the results show unequivocally that religiosity does influence donations practices, and so being a predictor of donations practices. Moreover, pro‐social behaviour is a predictor of donations practices when in the case of volunteerism, but not in the form of compassion.
  • The findings are particularly useful for nonprofit organizations that want to attract and retain individual charitable donors and may also help to increase donation regularity, to obtain higher amounts, and donations both to religious and to secular organizations. Finally, it can be stated that the understanding of religiosity sheds light on knowledge about donations practices, and that this study also makes an important contribution to academia, as it is the first study conducted in Portugal that assesses the drivers of donations practices.
