This paper disentangles the age-productivity-wage nexus by estimating productivity and wage equations with longitudinal employer-employee
panel data for Belgium. Results indicate that workers above 49 years are significantly less productive than their younger
colleagues. Moreover, while relative productivities across age groups are not found to differ significantly between ICT and
non ICT firms, the upward sloping age-wage profile appears to be somewhat steeper in ICT firms. Yet, whatever the ICT environment,
findings show that young workers are paid below and older workers above their marginal productivity. This pattern is in line
with the deferred payment model developed by Lazear (J Polit Econ 87:1261–1284, 1979). 相似文献

This paper tests experimentally, in a common value setting, the equivalence between the Japanese English auction (or clock auction) and an oral outcry auction where bidders are allowed to call their own bids. We find that (i) bidding behaviour is different in each type of auction, but also that (ii) this difference in bidding behaviour does not affect significantly the auction prices. This lends some support to the equivalence between these two types of auction. The winner's curse is present: overbidding led to higher than expected prices (under Nash bidding strategies) in both types of auction. Although interesting and encouraging, the results clearly indicate that further research is necessary, particularly with a modified experimental design. 相似文献

Three second-order factorial models are defined, using the LISREL notation, to assess the univocity of a construct. The first model assumes that the constructs are heterogeneous, the second that they are homogeneous. The third model introduces the notion of partial homogeneity between constructs. Partial homogeneity is defined in terms of a LISREL second-order factor model. In some cases, this model offers a viable alternative to the collapsing of items into a unique scale. An example is given of scales which fit the partial homogeneity model. 相似文献

We develop a political economy model of sovereign debt that shows that income inequality leads to popular pressures on the government to use foreign debt to finance a redistribution of income at the expense of productive public investment. Recognizing this fact, international lenders impose credit ceilings with the consequence that developing country borrowers invest less and grow slower. 相似文献

The debate over the use of tariffs or value added taxes in developing countries has focused on the difficulty of collecting
VAT from the informal sector. This paper contributes by considering this issue with heterogeneous firms and endogenous entry.
This yields two results. First, a cut in the tariff reduces the size of the informal sector. Second, the imposition of VAT
need not increase the size of the informal sector. Turning to simulation results, we find that switching from a tariff to
a revenue-neutral VAT increases welfare, in part because of the selection effect generated by heterogeneous firms. 相似文献

The authors offer a new perspective to the field of guaranteed minimum death benefit contracts, especially for simple return premium and rising floor guarantees. A particular feature of these contracts is a guaranteed capital upon the insured's death. A complete methodology based on the generalized Fourier transform is proposed to investigate the impacts of jumps and stochastic interest rates. This paper thus extends Milevsky and Posner (2001). If jumps alone are considered, similar results are obtained, but, when stochastic interest rates are introduced, the fair costs of the guarantee feature are found to be substantially higher in this more general economy. 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.
