This paper provides a discrete time algorithm, in the framework of the Cox–Ross–Rubinstein analysis (1979), to evaluate both
Parisian options with a flat barrier and Parisian options with an exponential boundary. The algorithm is based on a combinatorial
tool for counting the number of paths of a particle performing a random walk, that remains beyond a barrier constantly for
a period strictly smaller than a pre-specified time interval. As a result, a binomial evaluation model is derived that is
very easy to implement and that produces highly accurate prices.

The tendency to be an entrepreneur may be influenced by genetic variation. Sensation seeking is more common among entrepreneurs
than among the general population. Twin studies show that the tendency to be an entrepreneur is heritable and that common
genes influence both sensation seeking and entrepreneurial tendency (Nicolaou et al. Manag Sci 54:167–179, 2008a; Strateg Entrep J 2:7–21, 2008b). Since dopamine receptor genes have been associated with novelty seeking/sensation seeking (Benjamin et al. Nat Genet 12:81–84,
1996; Ebstein et al. Nat Genet 12:78–80, 1996; Noblett and Coccaro Curr Psychiatry Rep 7:73–80, 2005), and attention deficit hyperactivity disorder (ADHD) has been reported to occur at greater rates among entrepreneurs, we
examined the association between five dopamine receptor genes and four ADHD-associated genes, with the tendency to be an entrepreneur
in a sample of 1,335 individuals from the UK. We found a single nucleotide polymorphism (rs1486011) of the DRD3 gene on chromosome 3 to be significantly associated with the tendency to be an entrepreneur. This result is the first evidence
of the association of a specific gene with entrepreneurship. Further studies are needed to replicate this association. 相似文献

AbstractAlthough relevant analytical developments were provided over time by the critique of economic theory, they did not succeed in inhibiting the occurrence of a full-fledged revival of the neoclassical interpretation of capitalism. The development of critical economics and its capability of checking the influence of the dominant economic culture have been especially prejudiced by the failed integration between the analyses of Marx and Keynes. Following Keynes, once the ‘inducement to invest’ had been singled out as the central question for the explanation of output levels, one should have promptly acknowledged that on this very question Marx's analysis was significantly richer and more relevant than Keynes's—the richness and relevance of the former ultimately resting on the great attention Marx dedicated to the complex question of the influence of income distribution on the capitalists’ incentive to invest. It is argued in the article that through the study of this influence Marx succeeded in putting together the essential elements of a critical theory of effective demand, based on the principles and mechanisms that govern the distribution of income between profits and wages. 相似文献

Si dimostrano delle condizioni del primo ordine, alcune necessarie e altre sufficienti per problemi di minimax di tipo discreto, utilizzando prevalentemente il teorema dell'alternativa di Motzkin.

In this paper discrete minimax problems are considered.Some first order optimality conditions for minimax problems in hypothesis of different kind about the set of constraints are proved.We don't suppose that the set is convex, as treated by V. F. Dem'yanov and V. M. Malozemov.For the proofs it has often been used the alternative Motzkin's theorem.

The Determinants of Organizational Change and Structural Inertia: Technological and Organizational Factors 总被引:1,自引:0,他引:1
There are a growing body of theoretical work, wide anecdotal evidence, and a few large-scale empirical studies supporting the view that business firms quite rarely change their organizational structure, a phenomenon usually referred to in the literature as structural inertia. The present paper aims to analyze empirically the determinants of structural inertia and organizational change. As far as we know, this work constitutes the first attempt to directly address such issues through econometric estimates based on a large, longitudinal dataset at plant level. For this purpose, we consider changes of the organizational structure within a sample composed of 438 Italian manufacturing plants observed from 1975 to 1996. More precisely, we specify and test a duration model of the likelihood of an individual plant changing the number of hierarchical tiers after a spell r, provided that no change has occurred up to T. We also analyze the direction of change, distinguishing increases from decreases of the number of managerial layers. We consider a set of plant- and industry-specific explanatory variables that are expected to induce or oppose organizational change. The findings show that the adoption of advanced manufacturing technologies and new human-resources management practices favors organizational change. On the contrary, the presence of sunk costs and the extent of influence activities figure prominently in explaining structural inertia of business organizations. 相似文献

The category of “new religions” is somewhat controversial, but fringe minorities remain an interesting starting point in order to assess the future of religion. Contrary to what many expected in the 1970s, interest in religion in general has not declined in the Western world, organized religion has not disappeared, and we have not witnessed an explosion of “cults”. Learning from these past sociological prophecies that failed, we may speculate on the future in more realistic terms. New religious movements will not disappear, but they will not meet with an exceptional success either, this paper predicts, because models marginalizing them as based on brainwashing or being a form of religious kitsch, although criticized within the academic community, serve a basic psycho-cultural need of explaining away unpopular choices of our fellow human beings, and will probably not disappear from popular and media prejudice. 相似文献

This paper has two principal objectives. Using a tax‐benefit microsimulation model and the 1998 micro data of the Bank of Italy survey of household income and wealth, we first study the distributional effects of the current Italian income maintenance system and highlight its main defects and limitations, concerning in particular its unequal coverage of the population and its low efficiency in fighting poverty. The second aim is to describe and analyse the reforms recently implemented in this field; in particular, the Italian government has reformed the targeting criteria and introduced three new cash transfers. We describe these reforms both in their institutional characteristics and in their likely distributional consequences, and examine whether and to what extent they are able to overcome the shortcomings of the current system. 相似文献
