This article examines the lapse risk inherent to the guaranteed lifelong withdrawal benefit option embedded in a variable annuity product valuated from a pure derivatives perspective, that is, as a Bermudian option given to the policyholder. We assume rational behavior and quantify the potential impact of the lapse risk, defined as the difference between no lapse and optimal lapsing. We develop a sensitivity analysis that shows how the value of the product varies with the key parameters, and calculate the fair fee using Monte Carlo simulations. Empirical analyses are performed and numerical results are provided.  相似文献

The US Immigration Reform and Control Act of 1986 (IRCA) increased the monitoring of illegal employment and fined employers who hire undocumented immigrants. Since these provisions tax immigrant wages, it might be expected that the immigrant-native wage gap would increase after IRCA. This hypothesis is explored by decomposing immigrant-native wage differentials before and after IRCA. It is found that (i) the immigrant-native wage gap increased; (ii) in each year most of this gap was due to individual and job characteristics; (iii) the change in the gap is due primarily to overvaluation of native characteristics and to a lesser extent to undervaluation of immigrant characteristics.  相似文献

We study the effect of the reduction in the VAT rate on hairdresser services from 17.5 to 6% in the Netherlands in January 2000. Following Kosonen (J Public Econ 131:87–100, 2015), we use differences-in-differences to estimate the effects of this reform, with beauty salons as the main control group. In our preferred specification, we find close to full pass-through of the VAT cut into lower prices. However, we find no statistically or economically significant effect on the volume of sales or employment.  相似文献

We study economies that involve both small and large traders as well as the choice of a public project. Within this framework, we establish two sufficient conditions under which the set of competitive allocations coincides with the core. Our first core equivalence result holds under the assumption that there is a countably infinite set of large traders similar to each other. The second result, independent of the number of large traders, requires the existence of a coalition of small traders with the same characteristics of the large traders. Finally, we show how the generalized Aubin approach to cooperation may dispense with both conditions.  相似文献

Digital transformation has undoubtedly become a key enabler of innovation as evidenced by the numerous firms that use digital technologies to manage their innovation processes. This issue is even more relevant today when innovation processes have become more open and require greater resources in the different implementation phases to capture and transfer knowledge within and outside the firm's boundaries. This implies additional challenges in managing the increasing amount of knowledge and information flows. Accordingly, digital technologies can be used and implemented to manage open innovation processes through easier access and sharing the knowledge created and transferred. Nevertheless, literature in these fields does not provide a structured view of how and why digital technologies are used to manage innovation processes in an open perspective. This paper aims to bridge this gap by adopting the theoretical lenses of change management to identify the managerial actions at organizational and process level that companies perform to implement digital technologies in their open innovation processes. Accordingly, the paper investigates how and why these managerial actions required for and enabled by digital technologies help firms to develop and nurture open innovation. From an empirical point of view, the exploratory multiple case study analyzes nine firms operating in different industries and varying in size, market share, and organizational structure.  相似文献

Abstract

Little is known about the efficacy of many of the newer forms of online recruitment. Using a quasi-experimental design, we tested the impact of individual exposure to corporate recruitment websites and Facebook on perceptions of organizational familiarity and organizational image over time. Most interestingly, we found evidence of a curvilinear or non-linear relationship between frequency of exposure to organizational communications and perceptions of organizational familiarity across time. Implications of our findings for HR theory and practice are discussed.  相似文献

For an exchange economy with finitely many agents and a commodity space which is infinite dimensional, it is proved that competitive equilibria are the same as allocations belonging to the fuzzy core of the economy. The latter is further characterized as a subset of the ordinary core of a suitably associated continuum economy.
Riassunto Per un'economia di puro scambio con un numero finito di agenti e uno spazio dei beni di dimensione non necessariamente finita, si prova che gli equilibri Walrasiani possono essere caratterizzati come allocazioni che appartengono al nucleo fuzzy dell'economia. Inoltre, queste ultime allocazioni sono in corrispondenza biunivoca con allocazioni di tipo semplice che si trovano nel nucleo ordinario di un'opportuna economia che ha [0,1] come spazio rappresentativo dello spazio degli agenti.

Design is defined as a strategic competency that can be utilized in order to create new objects, artifacts (i.e. products), systems and services, starting with some idea about customer needs. Since the products and services from the design process are of strategic importance to the company, design knowledge itself can become a strategic asset. Although one might expect design to be an internal resource from the point of view of transaction costs, most companies only possess some design competencies and acquire creative design skills from design consultants. The important issue is how they delineate what is strategic and what is not strategic, but skills. The article is based on two case studies from the furniture industry in which the companies have found different solutions. In the paper we therefore explain the differences in terms of the resource-based view on strategy. This indicates different conceptions of design resources, operating in different, but comparable contexts.  相似文献

Roger Horowitz opens Putting Meat on the American Table: Taste,Technology, Transformation with the observation that Americais a meat-eating nation. Throughout his narrative, he examinesthe forces that allow so much meat—six to eight ouncesper person per day—to satiate Americans’ appetite.The central questions driving Horowitz’s analysis are(a) what is the relationship between producing and consuminga product and (b) how does the nature of the good affect thisrelationship?
