In this paper we present a quantitative analysis of the evolution of some Internet and ICT evolution indicators. It focuses on the number of Internet hosts, the Internet penetration index, the ICT development index and the software/protocols development. In addition, we analyzed the series of most impacting events building up the Internet along the last fifty years. These analyses were carried out using the multi-logistic procedure recently proposed by the authors. Our results for hosts counting, penetration index and software/protocols development are compatible with the onset of some radical changes in the Internet technology to be currently underway and we forecast new growth rate peaks to occur by 2015. The software/protocols were found to having been powered by bursts of creativity with periods of the order of the Kuznets and Kondratiev economic cycles. Similar conclusions were drawn from the series of main events building up the Internet. Despite the clear signs of worldwide improvement in the ICT infrastructure and usage between 2002 and 2007 obtained from the ICT development index, its cross-correlation with the human development index (HDI) revealed the presence of a group of countries whose improvements in the operational ICT index are disconnected from their corresponding HDI improvements. 相似文献

Abstract This paper aims to illustrate the benefits that accrue from critical realism's sustained, explicit reflection about ontological issues. The paper pursues this aim by examining the work of radical subjectivist Austrian economists as it has developed since the post-1974 revival in the fortunes of the Austrian school, focusing in particular on their account of the generation of socio-economic order in decentralized market economies. Ambiguities and tensions can be discerned in the radical subjectivist account of the causal forces at work in the market process. It is argued that the conceptual resources required for resolving those tensions and ambiguities are to be found in critical realism. The final section of the paper draws out some of the broader implications of the suggested resolution for radical subjectivist Austrian economics. 相似文献

The paper addresses the problem of Fed control of the money supply and the inherent instability of a fractional reserve banking system which Friedman covered in A Program for Monetary Stability. While Friedman proposed a 100 percent reserve requirement as a solution, this work suggests a change from imposing legal reserve ratios on specific liabilities to one of imposing them on total bank liabilities. Reserve ratios are compared to tax rates. Friedman's proposal is to increase the tax rate to 100 percent on specific liabilities and pay interest on reserve balances at the Fed. The proposal of this paper is to keep the tax rates (present reserve ratios) but change the tax base. It is shown that the Fed would gain control over the maximum expansion of banks, but would lose direct control over specific liabilities. The Fed would not tax some liabilities and subsidize others. The Fed could concentrate on setting the tone of the money market and allow the public to use whatever set of bank liabilities it desires as money without specific penalty. 相似文献

This paper extends the usual instrument-target framework by directly estimating macroeconomic policy preferences over a number of policy targets using a derived reduced form and then solving the nonlinear optimality conditions for optimal instrument choice. Solving the optimality equations using observations on predetermined variables yields the implicit set of preference weights which induced the observed choices. The derivation format parallels the integrability discussions about consumer preferences implicitly expressed through demand functions. The approach is applied to a simple macro model estimated over the period from 1955 through 1972. 相似文献

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run. 相似文献

We suggest using information from the state register of personal cars as an alternative indicator of economic inequality in countries with a large share of shadow economy. We illustrate our approach using the Latvian pool of personal cars. Our main finding is that the extent of household economic inequality in Latvia is much larger than officially assumed. According to Eurostat, the officially published estimate of the Gini coefficient for Latvia is 0.374 for 2009, which is much higher than the Gini coefficient value reported for all the 27 EU member countries (0.304), but significantly lower than 0.48 according to our results. 相似文献
