We study the merits of capped retirement products with guarantee for investors who have the flexibility to dynamically adjust their investment strategy. All contracts under consideration are fairly priced such that the net profit of the provider is zero. Without the rider, an expected utility maximizing CRRA investor does not want an investment cap. Here, she commits herself to a strategy a priori. With the flexibility rider, the optimization problem changes and the optimal strategy is a response to an exogenously set price. A fair pricing then anticipates the optimal response of the investor. We show that the maximum expected utility of the investor can, for anticipated fairly priced products, be obtained for a finite cap. Thus, a capped product design can give a Pareto improvement to the otherwise uncapped contract version.  相似文献

The connection between broadband deployment and economic prosperity in the United States has garnered public attention due to stimulus plan funding authorized in February 2009 for broadband planning and deployment initiatives. The importance of innovation for a nation's economic well-being is fairly well understood. Through a literature survey, this article analyzes the connection between information and communications technologies and economic growth, as well as the connection between broadband and economic growth. There appears to be a positive economic impact from expanded broadband deployment and adoption. However, various research challenges including methodological problems and access to sufficiently granular data have prevented the authors from drawing more definitive conclusions from the US broadband experience. Another finding is the time lag for businesses to effectively exploit innovative broadband applications.  相似文献

This paper presents a model of strategic product choice when consumer preferences combine features of both horizontal and vertical product differentiation. Consumers disagree on what amount of a "special" characteristic makes for a better product, but those who prefer more of this attribute are willing to pay more for it. Within this demand structure, I examine the advantages of first-mover firms. I find that such firms typically do best in markets where the maximum degree of product differentiation is limited by preferences rather than technology. These are "niche markets". Follower firms do better in markets in which the range of preferences is broad relative to the span of feasible goods.  相似文献

After studying the effects of Louisiana’s post-hurricane “thank you” campaigns, the researchers find expressions of gratitude significantly improve perceptions of Louisiana in the midst of its recovery. Through a national survey conducted November 2006, they find that those who saw or heard a thank you advertisement have more positive attitudes toward the state and its people, a greater willingness to pay a premium for its products, services and travel to the state, and spread positive word-of-mouth, thus justifying the use of public funds to support the campaign. The authors investigate the role of participation on the effectiveness of expressions of gratitude and identify the mediating role of affective commitment in driving the positive results attributed to expressions of gratitude.  相似文献

After the breakdown of the communist regime in Romania, collective farms were replaced by a large number of small-scale private farms. Although cooperation seems to be a favourable choice for these smallholders, it did not develop as perhaps expected. This article explores the factors that determine the formation of the intention of Romanian vegetable farmers to join marketing cooperatives in the form of so called producer groups. Our theoretical framework refers to Ajzen’s Theory of Planned Behaviour, which we model with a structural equation model. We identified as main intention drivers the expectation for better prices and easier access to capital. Perceived family support is another significant factor. The level of distrust is high. Although our trust variable is not significant as a predictor of the intention to cooperate in the model, we find qualitative indications that trust plays a role when the intention is translated into actual behaviour.  相似文献

Over the eighteen-month period ending June 1986, the Australian economy experienced two major shocks: a nominal devaluation of the $A of some 28 per cent and a terms of trade decline of some 16 per cent. The effects of these influences are examined using the ORANI model of the Australian economy. The effects of the devaluation on selected macroeconomic variables and key sectoral variables are presented for various degrees of wage indexation. Effects on quota rents are calculated and compared with actual outcomes. The terms of trade decline has an adverse impact on the balance of trade and in order to offset this impact while maintaining aggregate employment demand the model calculates that both real wages and real absorption would need to be around 4 per cent less than the values they would otherwise take.  相似文献
