Ziel des Beitrags ist die Beantwortung der Frage, welche Faktoren die Nutzung von Fernsehserien erkl?ren k?nnen. Kann sie
im Wesentlichen auf Habitualisierung und strukturelle Rahmenbedingungen zurückgeführt werden, oder l?sst sie sich dadurch
erkl?ren, dass die Erwartungen an die Qualit?t von Fernsehserien und die Wahrnehmung von Qualit?tseigenschaften der verschiedenen
Serien zwischen den Rezipienten variieren? Zun?chst werden die theoretisch relevanten Faktoren für ein Modell der subjektiven
Qualit?tsauswahl identifiziert und operationalisiert. Anschlie?end wird in einer empirischen Studie geprüft, ob diese Faktoren
einen Einfluss auf die Nutzung der Fernsehserien haben. Die Untersuchungsergebnisse zeigen, dass die drei Elemente des theoretischen
Ansatzes — Qualit?tserwartungen, Qualit?tswahrnehmungen und Qualit?tsurteile — die Seriennutzung zu einem betr?chtlichen Teil
erkl?ren k?nnen. Der Vorteil dieses Ansatzes gegenüber dem Uses and Gratifications Approach besteht darin, dass die Eigenschaften
des Angebots im Mittelpunkt stehen. Damit wird es m?glich, Aussagen darüber zu machen, welche wahrgenommenen Merkmale des
Angebots für die Nutzungsentscheidungen der Rezipienten relevant sind. 相似文献

Cost information sharing with uncertainty averse firms 总被引:1,自引:0,他引:1
Summary. A homogeneous Cournot duopoly with asymmetric information is analyzed. Every firm learns its own marginal cost parameter, but not the marginal cost parameter of the opponent. Every firm can commit to revealing its private information to the other firm, i.e. to share information. The influence of uncertainty aversion on the readiness of the duopolists to share cost information is analyzed. Uncertainty aversion is modeled according to the Choquet utility theory. It is shown that low uncertainty aversion leads the firms to share information, while high uncertainty aversion leads the firms not to share. A simple economic explanation for this result is given.Received: 5 January 2001, Revised: 7 May 2003, JEL Classification Numbers:

In early 2013, rumours about the euro‐appreciation gained momentum, which may lead to decreases in exports and increases in imports of the member states. Therefore, we investigate the impact of changes in the nominal euro exchange rate vis‐à‐vis major currencies on export and import performance of nine different euro‐area countries. To disentangle the ‘true’ equilibrium elasticities Stein's unbiased risk estimate (SURE) system error correction models (SSECM) are estimated for nominal exchange rate changes versus the rest of the world or other major currencies. To differentiate between price level changes and changes of the nominal exchange rate, a country's export and import equation is estimated using separately the nominal rate and the relative price/unit labour cost as regressors. Results of Wald tests indicate that assuming both variables to have the same influence on exports and imports is misleading. Whether the relative price/unit labour costs elasticities are high or low depends crucially on which indicator is chosen, while the effect of nominal exchange rate changes can be estimated robustly for all countries in the sample. In particular, France and Spain are hit by a euro‐appreciation since their exports are highly exchange rate elastic. However, for France, this effect is at least partly offset by an also negative exchange rate elasticity of imports. 相似文献

Unions are an important indicator of various measures of firm performance in Anglo‐Saxon countries. The same is true for the German analogue of the workplace union, the works council. Using German establishment data, I examine the impact of works councils on further training. I employ pooled logit and count‐data models to analyse the further training activity and intensity of German firms. Because the treatment variable may suffer from endogeneity, I also adopt linear and nonlinear instrumental variable techniques. The analysis reveals a positive impact of works councils on firm‐provided training and provides slightly weaker evidence for firm‐size differentials in workplace representation. I conclude that enhanced management–employee relations foster the training efforts of firms. 相似文献

Total Factor Productivity, the East Asian Miracle, and the World Production Frontier. — The post WWII growth of the East Asian Tiger states has stimulated the discussion about its determinants. Young and Krugman hold that high capital accumulation rather than gains in efficiency or technological progress has spurred growth. Nelson and Pack, however, have recently criticized the methods of measuring technological progress. Applying the nonparametric approach to frontier production function determination and the Malmquist index of total factor productivity change, the authors take up this criticism. They calculate productivity indicators for a sample of 18 American, Asian, and European countries. For the Tiger states, their results confirm that capital accumulation was the main source of growth in 1960-1973, whereas they find evidence for an increasing importance of efficiency improvements for the growth in 1973-1990. 相似文献

Recent studies have pointed out that monetary shocks in sticky price models cannot generate real exchange rates that exhibit delayed overshooting and are highly persistent. This paper demonstrates that such exchange rate dynamics can be generated by incorporating incomplete information about the true nature of the monetary shock into a standard New Keynesian model of a small open economy. 相似文献

The sources of aggregate productivity growth are explored using detailed data for four‐digit US manufacturing industries during 1958–96 and a decomposition formula that allows us to quantify the contribution of structural change. Labour productivity as well as total factor productivity are considered with either value‐added or employment shares serving as aggregation weights. It is shown that structural change generally works in favour of industries with increasing productivity. This effect is particularly strong in the years since 1990, in high‐tech industries and in durable goods producing industries. The impact of the computer revolution can be clearly identified. 相似文献
