We consider an economic model that features (1) a continuum of agents and (2) an aggregate state of the world over which agents have an infinitesimal influence. We first review the connections between the ??eductive?? viewpoint on expectational stability and standard game-theoretical rationalizability concepts. The ??eductive?? reasoning selects different plausible beliefs that are a priori, and possibly a posteriori, ??diverse??. Such beliefs are associated with the sets of ??Cobweb tatonnement?? outcomes, ??Rationalizable States?? and ??Point-Rationalizable States?? (the latter two being shown to be convex). In the case where our model displays strategic complementarities, unsurprisingly, all our ??eductive?? criteria support similar conclusions, particularly when the equilibrium is unique. With strategic substitutabilities, the success of expectational coordination, in the case where a unique equilibrium does exists, relates with the absence of cycles of order 2 of the ??Cobweb?? mapping: in this case, full expectational coordination would be achieved. However, when cycles of order 2 do exist, our different criteria predict larger sets of outcomes, although all tied with cycles. Under differentiability assumptions, the Poincaré?CHopf method leads to other global stability results. At the local level, the different criteria under scrutiny can be adapted. They lead to the same expectational stability conclusions, only when there are local strategic complementarities or strategic substitutabilities. However, for the local stability analysis, it is demonstrated that the stochastic character of expectations can most often be forgotten. 相似文献

December 1, 1996 a new law was implemented in Portugal to gradually reduce the standard workweek from 44 to 40 h. We study
how this mandatory reduction affected employment through job creation and job destruction. There was considerable regional,
sectoral and firm-size variation in the share of workers who were affected by the working hours reduction. We exploit this
variation to assess the impact of the workweek reduction. We find evidence that the working hours reduction had a positive
effect on employment through a fall in job destruction. 相似文献

We solve a model with two i.i.d. Lucas trees. Although the correspondingone-tree model produces a constant price-dividend ratio andi.i.d. returns, the two-tree model produces interesting asset-pricingdynamics. Investors want to rebalance their portfolios afterany change in value. Because the size of the trees is fixed,prices must adjust to offset this desire. As a result, expectedreturns, excess returns, and return volatility all vary throughtime. Returns display serial correlation and are predictablefrom price-dividend ratios. Return volatility differs from cash-flowvolatility, and return shocks can occur without news about cashflows. 相似文献

Method for identifying strategic objectives in strategy maps 总被引:1,自引:1,他引:0

This paper describes a simple tool for identifying strategic objectives as part of the design of strategy maps, based on the balanced scorecard, and meant to be used in organisations to establish performance indicators. To design the tool, a number of companies that implemented the balanced scorecard were analysed, in order to obtain their methodologies to create strategy maps. Three types of methods were found, different from each other in the way the strategic objectives are defined. By studying the benefits and drawbacks of the three methods, a simple, method was obtained. Basically, the method identifies general and specific strategic objectives and uses a modified SWOT (strengths, weaknesses, opportunities, threats) analysis. This paper also makes an analysis of the type of strategic objectives that the studied companies defined as part of the balanced scorecard implementation process. 相似文献

HETEROGENEITY IN REAL WAGE CYCLICALITY 总被引:2,自引:1,他引:1
Pedro S. Martins 《Scottish journal of political economy》2007,54(5):684-698
This paper presents evidence that real wage cyclicality can be a particularly heterogeneous parameter, depending on different worker characteristics and also on the specific stage of the business cycle. Using matched employer–employee panel data for Portugal covering the period 1986–2004, real wages are shown to be considerably more procyclical during recessions than during expansions, resulting in relatively moderate overall levels of cyclicality (about −0.6). However, most of the procyclicality during downturns is shown to be driven by the younger employees, as older workers appear to be insulated from the business cycle. Moreover, movers between firms typically display higher cyclicality than workers that stay in the same firm, regardless of whether the latter move or not between job levels. Most results also hold when considering basic wages instead of total wages, except that the procyclicality of movers during downturns is substantially higher. 相似文献

A new characterization of the American-style option is proposed under a very general multifactor Markovian and diffusion framework.
The efficiency of the proposed pricing solutions is shown to depend only on the use of a viable valuation method for the corresponding
European-style option and for the transition density of the model’s state variables. Under a Gauss-Markov stochastic interest
rates setup, these new American option pricing solutions are shown to offer a much better accuracy-efficiency trade-off than
the approximations already available in the literature. This result is also used to price callable corporate bonds under an
endogenous bankruptcy structural approach, by decomposing the option to call or default into a European put on the firm value
plus two early exercise premium components. 相似文献

Strategic alliances,organisational learning and new product development: the cases of Rover and Seat
The importance of the automotive industry in the global economy is widely recognised. The sector has undergone enormous changes in order to prepare for the fierce competition of the 21st century. Among these transformations, the most relevant are those technologies developed for the rapid evolution of activities linked to new designs, new products, and new manufacturing processes and systems. Innovative Japanese carmakers have stimulated international performance comparisons in these activities. International technology alliances may be one way of gaining access to new competitive technologies. Risks and costs associated with new product development can be shared among the partners and more effective use can be made of manufacturing facilities and production capabilities. Sometimes, an alliance agreement may lead to the deployment of new capabilities. However, in spite of this potential, the literature presents the success rate of alliances at less than 50%. Our study considers two examples of companies that developed international joint ventures (IJVs): Rover with Honda, and Seat with Volkswagen. Since these two European peripheral companies, Rover and Seat, no longer remain as independent firms, we are interested in identifying the reasons leading to the success or failure of these IJVs as regards the New Product Development (NPD) process. In particular, in both cases the paper looks at the problems of the weaker partner becoming increasingly dependent on the other partner and the need for a well-defined strategy to benefit from IJVs. 相似文献

A strong dichotomy has traditionally been established between qualitative and quantitative approaches. This question has been the subject of intense debate from a methodological point of view, and in recent years there are clear signs that the conflict is being overcome; nevertheless, we are still some way from a genuine position of complementarity and integration, and the issue remains to be considered in the process of theorization along the tortuous path that leads from the particular to the general. The proposal in this article takes a further step forward as regards this question, this time with respect to the study of interactive behaviour. The key is once again the consideration of a “complete unit” of analysis, but the logic of the observational methodology process enables the perspectives to be sequenced: the study begins with a predominantly qualitative approach before subjecting the data to a given type of recording (through the important support of field formats) and coding (preferably computerized), thus producing a matrix of formally interchangeable data; finally, the criterion is reversed and the study continues under a predominantly quantitative perspective. 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.

This paper investigates the influence of corporate governance on financial firms' performance during the 2007–2008 financial crisis. Using a unique dataset of 296 financial firms from 30 countries that were at the center of the crisis, we find that firms with more independent boards and higher institutional ownership experienced worse stock returns during the crisis period. Further exploration suggests that this is because (1) firms with higher institutional ownership took more risk prior to the crisis, which resulted in larger shareholder losses during the crisis period, and (2) firms with more independent boards raised more equity capital during the crisis, which led to a wealth transfer from existing shareholders to debtholders. Overall, our findings add to the literature by examining the corporate governance determinants of financial firms' performance during the 2007–2008 crisis. 相似文献
