Shifts in Portfolio Preferences of International Investors: An Application to Sovereign Wealth Funds
We develop a dynamic general equilibrium model to analyze the macroeconomic effects of a shift in portfolio preferences of foreign investors. The model has two countries and two asset classes (equities and bonds). It is characterized by imperfect substitutability between assets and allows for endogenous adjustment in interest rates and asset prices. To illustrate the mechanics of the model, we calibrate it to analyze a transfer of reserves from central banks to sovereign wealth funds (SWFs). We look separately at two diversification paths: a shift away from dollar assets (path 1), and a shift away from US bonds to US equities (path 2). In path 1, the dollar depreciates and US net debt falls on impact and increases in the long run. In path 2, the dollar depreciates and US net debt increases in the long run. 相似文献

This paper applied cost-effectiveness analysis to the use of drug therapy in the treatment of AIDS. The empirical approach adopted overcame the facts that the samples of patients had varying clinical prognoses, had variable entry dates into the samples and, because AIDS is a terminal disease, had variable exit dates. Holding these variables constant, administration of the drug AZT proved to be a less costly alternative than other existing palliatives for AIDS. The sub-sample of patients treated with AZT had lower hospitalization costs, lower caring costs and sufferers had an increased ability to continue to participate for longer as economically active members of society. 相似文献

The undeniable success of order-maintenance policing (also community policing or broken windows policing) is despite the deficiency in the theory which propelled the practice into policy: Wilson and Kelling's broken windows theory. We discuss what is wrong with the theory and why it nevertheless works when put into practice. 相似文献

We generalize May’s theorem to an infinite setting, preserving the elementary character of the original theorem. We define voting scenarios and generalized voting scenarios, and prove appropriate versions of May’s theorem. The case of generalized voting scenarios specialized to a countably infinite set of voters and the collections of all coalitions that have asymptotic density, shows that majority rule is the only aggregation rule that satisfies neutrality, irrelevance of null coalitions, anonymity, and positive responsiveness. 相似文献

Effective communication of capital investment proposals can be critically important to an engineer's professional development. Engineers frequently have difficulty developing this effective communication, however, primarily because they lack a clear understanding of the corporate decision-makers' commercial perspective and related informational needs. The decision-makers' perspective and the capital budgeting process are explored and several communication strategies are suggested to assist the engineer in more effectively presenting his capital investment proposals. The value of communication technique and the importance of recognizing and dealing effectively with certain psycho-social factors in inter-personal communication are briefly described. 相似文献

Abstract If we calculate the Policy-Values of a Whole Life Assurance for a given Age at Entry and a given Duration, but for several equidistant rates of interest, we find that the proportion of two successive values is very nearly constant. This fact is illustrated by Tables 1 a and 1 b, giving certain Policy Values on the basis HM and A 24–29 respectively, for the rates of 3, 4, 5 and 6 % of interest. Tables 2 a and 2 b show, that the same applies, if to a smaller degree, to Endowment Assurances. 相似文献

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market. 相似文献

Across three decades numerous metropolitan regions have made substantial investments in different tourist amenity packages. These investments were made to either capture a portion of the growing tourism market or establish an image that attracted the human capital needed to advance economic development. This article analyzes the returns for the tourism industry and for economic development from different amenity packages and finds those related to sports and amusements generated the most significant gains for regions. 相似文献

Previous studies have highlighted the question of government loan interest as one of great current importance. Government borrowing levels are high, and reducing interest payments would generate savings to meet other spending needs and/or to lower taxation, thus supporting the sustainability of public finances. However, no previous study has presented a method for a local government to calculate its own credit risk and thus be in a position to negotiate lower interest rates on its borrowing. This article defines a financial model that enables local governments to estimate the interest rate payable on a bank loan, based on their credit risk premium, in accordance with the Basel II rules and the findings of our empirical study of large local governments. 相似文献
