Since the theory of the adjustment time in a neoclassical growth model was first published close to two decades ago [Sato Sato, February 1963, Sato, June 1964], there have appeared a number of interesting articles dealing with different aspects of adjustment time and economic growth. The purpose of this note is to verify the original conclusions in the framework of variable elasticity of substitutions (VES) production functions. All of the other assumptions are preserved. The results indicate that the original assertion concerning the length of time needed for 90 percent of the adjustment applies to a non-Cobb-Douglas production function as well. “Vicinity” (90%) of the new equilibrium can be reached only after a sufficiently long period of time—approximately 100 years on the average. Furthermore, the pattern of adjustment for this model is very similar to that of the original model. 相似文献

Insurers can exploit the heterogeneity within risk-adjustment classes to select the good risks because they have more information than the regulator on the expected expenditures of individual insurees. To counteract this cream skimming, mixed systems combining capitation and cost-based payments have been adopted that do not, however, generally use the past expenditures of insurees as a risk adjuster. In this article, two symmetric insurers compete for clients by differentiating the quality of service offered to them according to some private information about their risk. In our setting it is always welfare improving to use prior expenditures as a risk adjuster. 相似文献

With the recent diffusion of broadband (BB) services, Internet protocol (IP) telephony is expected to spread significantly in Japan. This article investigates the demand for IP telephony by using conjoint analysis. Projecting IP telephony demand also contributes to Japanese info-communication policy discussions. Two points are made. First, IP telephony is still currently considered an optional supplement or an add-on service option of high-speed BB Internet access services in Japan rather than a close substitute of existing plain old telephone service (POTS). At this point, we find little evidence that many households will promptly forsake their fixed line service for IP telephony. Second, we conclude that the key condition for the proliferation of IP telephony is the complete guarantee of quality of service (QoS), including voice quality, number portability, fax usage and emergency access, comparable to or exceeding that of existing POTS. 相似文献

In this study, we analyse the relationship between interest rates on government bonds (GB) and the fiscal consolidation rule by using an overlapping generation model with endogenous and stochastic growth settings. Our key findings are summarized as follows. First, contrary to conventional view, we find that interest rates on GB may decline as public debt accumulates relative to private capital. Second, the simulation reveals that the economy may exhibit discrete changes with divergent interest rates, implying that the observed trend of relatively low interest rates on GB with public debt accumulation may not continue indefinitely in the future. Third, fiscal consolidation rule plays a key role in determining equilibrium interest rates. 相似文献
