In this paper, we estimate own-price elasticities for fixed network voice telephony access and national calls services for
private users as well as cross-price elasticities to mobile services using time series data from 2002 to 2007 from the Austrian
markets. Using instrumental variable estimates and considering cointegration, we find that access is inelastic while calls
are elastic. We conclude that the retail market for national calls of private users can probably be deregulated due to sufficient
competitive pressure from mobile. Access-substitution on the other hand does not seem to be strong enough to justify de-regulation. 相似文献

This paper studies the relationships between foreign currency debt, macroeconomic volatility, and risk premia in a model of a small open emerging market economy. The external value of the local currency is counter-cyclical, so that foreign currency debt requires larger repayments than local currency debt in bad states of nature. The level of foreign currency-denominated debts, therefore, affects the volatility of aggregate demand and by extension of the exchange rate. Exchange rate volatility is in turn an important determinant of the risk premium on local currency debt. Finally, this risk premium is a major factor in the choice of local versus foreign currency for emerging market borrowers. The mutual endogeneity of foreign currency debt, risk premia, and macroeconomic volatility creates important feedback effects in the economy: small increases in international risk aversion may entail large amplification effects on macroeconomic volatility since domestic borrowers substitute towards cheaper but riskier foreign currency debt finance. 相似文献

New Keynesian dynamics in a low interest rate environment 总被引:1,自引:0,他引:1
Recent research has found that the dynamic properties of the New Keynesian model are unorthodox when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large. This paper provides evidence that these results are not empirically relevant. We show that a prototypical New Keynesian model fit to Japanese data exhibits orthodox dynamics during Japan's episode with zero interest rates. We then demonstrate that this specification is more consistent with outcomes in Japan than alternative specifications that have unorthodox properties. 相似文献

Past approaches to correcting for unit nonresponse in sample surveys by re-weighting the data assume that the problem is ignorable within arbitrary subgroups of the population. Theory and evidence suggest that this assumption is unlikely to hold, and that household characteristics such as income systematically affect survey compliance. We show that this leaves a bias in the re-weighted data and we propose a method of correcting for this bias. The geographic structure of nonresponse rates allows us to identify a micro compliance function, which is then used to re-weight the unit-record data. An example is given for the US Current Population Surveys, 1998–2004. We find, and correct for, a strong household income effect on response probabilities. 相似文献

There is often a vast difference between the needs of the tourism industry and tourists on the one hand and of the local inhabitants of developing tourist destination areas — especially in Third World, rural settings — on the other hand. This article describes some of the problems associated with tourism development in general and discusses tourism development in terms of the psychological saturation effects it can have on local inhabitants. The authors state that tourism could enhance the development of rural areas on an ecologically and economically viable basis, and improve the quality of life of the rural black. They further state that it is possible to reconcile the needs and demands of locals and those of tourism through adequate planning and the development of effec‐tive intra‐ and intercultural communication systems. Using the Kosi Bay area of the Maputaland region in northern Natal as a case‐study, specific suggestions are offered about ways in which this process of need reconciliation can be built into tourism plan‐ning and into the development of a meaningful infrastructure for tourism. 相似文献

Many regulated industries involve an oligopoly market structure. We examine optimal incentive regulation for a duopoly model of spatial competition when firms have private cost information. Market structure is endogenous as regulation determines market segments for firms and output distribution across consumers in each firm's market. By varying the assignment of consumers to firms, a relatively more efficient firm can be rewarded with a larger market, thus reducing quantity incentive distortions. We derive the optimal policy, assess the impact of asymmetric information relative to full information, and examine extensions to allow for ex ante asymmetries in firm structure. 相似文献

This article deals with the question whether there exists a trade-off between inflation and unemployment in the short as well as in the long run in the Belgian economy. A wage-price model incorporating the phenomenon of price expectations is presented. The model is verified empirically and an inquiry is made into the dynamic characteristics of Belgium's wage-price nexus. The main results of the paper are first that a positive answer may be given to the question we asked ourselves and secondly, that the possibility of explosive behaviour of wage and price changes is to be excluded. 相似文献

Recently there has been an increased attention towards the ex-post evaluation of competition policy enforcement decisions and in particular merger decisions. In this paper we study the effects of two mobile telecommunication mergers on prices. We apply a standard difference-in-differences approach which is widely used in the literature on ex-post evaluation of mergers. For the Austrian T-Mobile/tele.ring merger, we conclude that after the acquisition (for which remedies were imposed) prices in Austria did not increase relative to the considered control countries. For the Dutch T-Mobile/Orange merger, we observe an increase in the mobile tariff prices in the Netherlands in the analysed period, relative to the control countries. We cannot firmly establish whether this price increase was exclusively caused by the T-Mobile/Orange merger or in part by possible price effects brought about by the KPN/Telfort merger consummated two years earlier in the Netherlands. However, we believe that such price increase could be linked to the structural changes brought by both KPN/Telfort and T-Mobile/Orange mergers together. 相似文献

This paper introduces the dynamical framework which combines product and process innovations. The model contributes to the theoretical literature on innovations in two ways. First, it permits for the simultaneous dynamics of both types of innovations which is rarely considered in the literature. Second, the products being generated by the innovations are heterogeneous in their investment characteristics. This allows for the formation of the dynamic interdependency between both types of innovations. As a result, the steady-state levels of process innovations for each product are different and influence the dynamics of product innovations in turn. 相似文献
