During the Reagan administration, the federal government mandated the use of cost–benefit analysis (CBA) for regulatory decisions involving $100 million or more. While the use of CBAs has increased, less attention has been given to CBA processes involving smaller expenditures (regulatory and nonregulatory). As the federal budget tightens in the years ahead, the need to make hard decisions about these policies, programs, and technologies will increase. This paper describes a CBA process developed for the Office of Strategic Planning of the Social Security Administration; it was designed to handle small-to-moderate expenditure decisions (or for preliminary estimates of larger undertakings). A sample CBA using this process is provided, along with a discussion of the lessons that were learned from an initial application.  相似文献

The paper considers how people should plan their saving, given certain assumptions about inheritance and changes in household circumstances. The results are produced by a model that takes into account tax and state benefits as well as various private savings vehicles. It concludes that, for many households, saving for retirement through a ‘pension’ might not be optimum and that the best strategy is to vary the incidence and allocation of saving in response to changes in household circumstances.  相似文献

We examine four issues pertaining to initial public offerings (IPOs) using a survey of 438 chief financial officers (CFOs). First, why do firms go public? Second, is CFO sentiment stationary across bear and bull markets? Third, what concerns CFOs about going public? Fourth, do CFO perceptions correlate with returns? Results support funding for growth and liquidity as the primary reasons for IPOs. CFO sentiment is generally stationary in pre‐ and post‐bubble years. Managers are concerned with the direct costs of going public, such as underwriting fees, as well as indirect costs. We find a negative relation between a focus on immediate growth and long‐term abnormal returns.  相似文献

By most accounts, the Internet and related advances in information technology significantly affect financial services in general and insurance markets and institutions in particular. Coupled with other important trends such as globalization and regulatory reform, these changes are forcing far‐reaching changes upon the insurance industry and making it more competitive. This article focuses specifically on the implications of the Internet for insurance markets and institutions. The conventional wisdom that the Internet constitutes a sufficient condition for the disintermediation of traditional insurance distribution networks is called into question. To the extent that the Internet reduces transaction costs, it will create opportunities for new intermediaries as well as for existing ones. It will also influence product design, in some cases making it economically attractive to unbundle and repackage various forms of coverage. By removing entry barriers and reducing insurance costs, the Internet will also provide a private market solution to a major insurance regulatory concern—enhancing insurance affordability and availability.  相似文献

Many financial services firms are offering the Internet as a self-service technology (SST), for online stock trading, in an effort to increase effciency and give customers greater access. It is important to understand how this technology will influence customer satisfaction. This paper reports results of exploratory research to identify sources of customer satisfaction and dissatisfaction with the service encounter in Thai stockbrokerage firms. Results show that customers and service providers determine sources of customer dis/satisfaction differently, depending on whether the service encounter is technology-based or interpersonal. Different customer profiles give rise to segmentation in response to the use of Internet technology in this industry.  相似文献

Japanese auto makers are reported to enjoy high supplier performance through long-term relationships, specific investments, and sole sourcing. Quality management consultants in the U.S. have been strongly advocating adoption of these practices. But economic and management theorists would predict that the combination of a high level of relationship-specific investments and sole sourcing will lead to problems with supplier performance. In fact the Japanese auto makers use a hybrid form of organization we term parallel sourcing. We present a transaction costs model that shows how parallel sourcing provides incentives for supplier performance associated with multiple sourcing while preserving claimed benefits of sole sourcing.  相似文献

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.
