This paper presents new evidence on the patterns of price and wage adjustment in European firms and on the extent of nominal rigidities. It uses a unique dataset collected through a firm-level survey conducted in 17 European countries and covering various sectors. Several conclusions are drawn from this evidence. Firms adjust wages less frequently than prices, on average every 15 and 10 months, respectively. Price and, especially, wage adjustment exhibit a substantial degree of time-dependence. In particular, wage changes tend to cluster at a specific time of the year, mostly January in the majority of countries. The results of a multivariate analysis indicate that prices are more flexible when competitive pressures in product markets are strong and when labor costs account for a lower fraction of firms' total costs, whereas wages are more flexible when bargaining is decentralized and when the coverage of collective bargaining and the stringency of employment protection legislation are low. Price rigidities are higher in firms with a larger share of high-skilled/white-collar workers. 相似文献

This paper analyzes how faculty members dynamically allocate their efforts between improving their research and teaching skills, taking into account the organizational structures and incentives implemented by academic institutions. The model builds on the assumption that organizational structures have an impact on the nature of spillover effects between teaching and research competencies. We analyze the dynamic equilibrium under unilateral and bilateral spillovers, using the no-spillover case as a benchmark. The bilateral spillover case is the most appealing as it achieves the highest overall performance; however, the nature of the equilibrium and the career paths can be quite different depending on the parameters of the problem such as the obsolescence of competencies or the strength of the spillover effect. This finding provides interesting insights on what could be the most productive configuration of a higher education institution. 相似文献

This study seeks to determine the reasons behind original shareholder sales of particular numbers of shares at the IPO date. It also examines whether share transfer behaviour reveals specific characteristics of blockholders and if a non-linear relationship emerges between the variable representing the shares held by controlling shareholders immediately prior to the transaction and the share transfer variable. The sample consists of 46 Tunisian companies listed on the Tunis Stock Exchange during the period 1992–2012. Results show that the original shareholders sale decision depends significantly on company growth opportunities. Assignee shareholders benefit from favourable stock market conditions when they sell their shares at the IPO time. Share transfer behaviour depends on whether company ownership consists of a family or not, and on whether the shareholders are blockholders or not. Besides, controlling shareholders benefit from IPO to enhance their ownership. 相似文献

Backward Stochastic Differential Equations in Finance 总被引:28,自引:0,他引:28
We are concerned with different properties of backward stochastic differential equations and their applications to finance. These equations, first introduced by Pardoux and Peng (1990), are useful for the theory of contingent claim valuation, especially cases with constraints and for the theory of recursive utilities, introduced by Duffie and Epstein (1992a, 1992b). 相似文献

For some companies, especially in the high technology sector, internationalisation is no longer a matter of choice, but of necessity. This paper explores the strategy development patterns of internationalising small high-technology companies in an environment where windows of opportunity close quickly. Findings from in-depth interviews suggest that emergent strategies within or outside established networks are likely to trigger small high-technology companies' initial internationalisation. Further overseas expansion is constrained by resource availability. This study demonstrates that internationalisation is an iterative process that happens in a holistic way much more than a systematic one. Rather than trying to fit small and medium enterprises' (SMEs') internationalisation patterns into a stage model, managers and policy-makers should recognise the importance of networks. Training and programs could, therefore, help identify strategic networks of importance for the companies and assist them in both contributing and taking advantage of these. 相似文献

In this article, we introduce a new theoretical international asset pricing model which accounts for partial financial market segmentation. We show that if some investors do not hold all international assets because of implicit and/or explicit segmentation factors, the world market portfolio is not efficient and the classic ICAPM must be augmented by a new factor reflecting the local risk undiversifiable internationally. We test this model empirically for a sample of emerging markets. Our findings show that the degree of market integration is time-varying and that the premium associated with the domestic risk factors is the most important component of the total risk premium. However, our results also show that most of the emerging markets we study have become more integrated in the end of our sample period as a result of liberalization and reforms. 相似文献

This paper introduces a new retailing concept called shopper-based mall equity (SBME). SBME is the differential effect of mall knowledge on shoppers' responses to a mall's marketing activities. The results of a study in two Canadian shopping malls consisting of 905 shoppers who were administered a questionnaire suggest that SBME is a bi-dimensional construct, composing two sub-scales, namely mall awareness and mall image. Further psychometric tests show a parsimonious SBME measure with support for convergent, discriminant and predictive validities. Multi-group latent mean structures show that the SBME measure is able to discriminate shoppers that globally attribute high-mall scores from those who globally attribute low-mall scores. The article includes theoretical and managerial implications. 相似文献

Managing inventory in reverse logistics has been receiving much attention in recent years. One inventory problem that has been of interest to researchers is the production and remanufacturing model, where used items are collected and remanufactured to satisfy customer demand. The available models in the literature do not discuss the learning effects in production and remanufacturing processes. This may not be true in industries where labour costs and learning costs are expensive. By modelling these learning effects, management may use established learning models to better utilize capacity, manage inventories, and coordinate production and distribution throughout the chain.This paper extends the production, remanufacture, and waste disposal model by assuming learning to occur in both production and remanufacturing processes. However, this paper also assumes that improvements due to learning require capital investment. Mathematical models are developed, numerical examples are provided, and results are discussed. 相似文献

Using a canonical trust game, we investigate whether the inequality of endowment between trustor and trustee and the acquired versus permanent financial state affect trust and trustworthiness. We found that trust and trustworthiness are reference‐dependent and that individuals with permanent financial state receive more trust and are more trustworthy than others. In our experiment, unequal endowments do not significantly affect trust, but trustworthiness increases significantly when the trustor is poorer. 相似文献
