Peering points between different Internet service providers (ISPs) are among the bottlenecks of the Internet. Multihoming (MH) and content delivery networks (CDNs) are two technical solutions to bypass peering points and to improve the quality of data delivery. So far, however, there is no research that analyzes the economic effects of MH and CDNs on the market for Internet connectivity. This paper develops a static market model with locked-in end users and paid content. It shows that MH and CDNs create the possibility for terminating ISPs to engage in monopolistic pricing towards content providers, leading to a shift of rents from end users and content providers to ISPs. Implications for future innovations are discussed. 相似文献

Recent work finds evidence that the volatility of the U.S. economy fell dramatically around the first quarter of 1984. We trace the timing of this so-called “Great Moderation” across many subsectors of the economy in order to better understand its root cause. We find that the interest rate sensitive sectors generally experience a much earlier volatility decline than other large sectors of the economy. The changes in Federal Reserve stabilization policies that occurred during the early 1980s support the view that an improved monetary policy played an important role in stabilizing real economic activity. We find only mild evidence that “good luck” was important and little evidence to support the claim that improved inventory management was important. 相似文献

This note considers the small sample bias of the empirical variances of observed and ex-post-rational prices of financial assets, and shows that this can be much more severe than has previously been thought. 相似文献

It is well known that goodness-of-fit measures lead to overfitting. We compare the small-sample properties of linear and several nonlinear models using a Monte Carlo study. A large number of linear series are generated and conventional methods of fitting nonlinear models are applied to each. The best linear and nonlinear models are compared using in-sample and out-of-sample criteria. Out-of-sample forecasts are shown to be superior for selecting the proper specification. The experiment is repeated using a nonlinear model and the in-sample lit and forecasts of the various models are compared. An example is provided using the term structure of interest rates. 相似文献

This paper proposes a definition of relative uncertainty aversion for decision models under complete uncertainty. It is shown that, for a large class of decision rules characterized by a set of plausible axioms, the new criterion yields a complete ranking of those rules with respect to the relative degree of uncertainty aversion they represent. In addition, we address a combinatorial question that arises in this context, and we examine conditions for the additive representability of our rules. 相似文献

Nuclear power has never been free from the stifling involvement of government. Heavy regulation has reduced the ability of entrepreneurs to develop and provide new means for the generation of energy using nuclear fuel. The strict parameters dictated by government officials are based upon outdated technology, an improper regulatory philosophy, and preclude innovation in nuclear power generation. Anti-market environmentalists misunderstand the implications of a free market in nuclear power and argue against it based on problems that are actually caused by government involvement. Our position is neither for nor against nuclear power. We advocate a hands-off policy where the nuclear industry is left to its own devices, free from governmental regulations and subsidies: free to succeed or fail on its own. Thus, our position is neither right-wing conservative (removing regulations), nor left-wing liberal (removing subsidies). Very much to the contrary of both positions, we propose a free-market in nuclear power. 相似文献

Reference groups and individual deprivation 总被引:1,自引:0,他引:1
We provide an axiomatization of Yitzhaki's index of individual deprivation. Our result differs from an earlier characterization due to Ebert and Moyes in the way the reference group of an individual is represented in the model. 相似文献
