Internationale Standortrankings sind in jüngerer Zeit zunehmend in die wissenschaftliche Kritik geraten. Sebastian Gundel
und Ulrich van Suntum analysieren im Folgenden, inwieweit eine kritische Studie zum L?nderranking von Ullrich Heilemann, Harald
Lehmann und Joachim Ragnitz1 ihrem wissenschaftlichen Anspruch selbst gerecht wird. Daran anschlie?end eine Erwiderung von Ullrich Heilemann, Harald Lehmann
und Joachim Ragnitz. 相似文献

Der für diese Legislaturperiode geplante zweite Teil der F?deralismusreform bietet die Chance eines grundlegenden Systemwechsels.
Wie k?nnen die widerstreitenden Finanzinteressen der Bundesl?nder mit den Anforderungen an die Anreizeffizienz des Systems
in Einklang gebracht werden?

We consider a financial market with one bond and one stock. The dynamics of the stock price process allow jumps which occur according to a Markov-modulated Poisson process. We assume that there is an investor who is only able to observe the stock price process and not the driving Markov chain. The investor's aim is to maximize the expected utility of terminal wealth. Using a classical result from filter theory it is possible to reduce this problem with partial observation to one with complete observation. With the help of a generalized Hamilton–Jacobi–Bellman equation where we replace the derivative by Clarke's generalized gradient, we identify an optimal portfolio strategy. Finally, we discuss some special cases of this model and prove several properties of the optimal portfolio strategy. In particular, we derive bounds and discuss the influence of uncertainty on the optimal portfolio strategy. 相似文献

Neben den Zahlungsverpflichtungen aus ihren Kreditmarktschulden haben die L?nder Versorgungsverpflichtungen gegenüber ihren
pensionierten Beamten. Wie hoch sind derzeit die expliziten Schuldenquoten der L?nder und wie hoch ist die Gesamtschuld aus
Versorgungsverpflichtungen und Kreditmarktschulden? In welchem Ausma? würde eine übernahme der Reformma?nahmen bei der gesetzlichen
Rentenversicherung auf die Beamtenversorgung die künftige Belastung der Haushalte verringern?

This paper proposes a new, production theory approach to the determination of the real exchange rate, which is defined as the relative price of traded to nontraded goods as is common in the international trade literature. Using a Translog real GDI function that describes the aggregate technology of an open economy as a starting point, the real exchange rate can be formally derived as a function of domestic excess savings, the terms of trade, relative factor endowments and technological progress. Empirical results for Switzerland suggest that the main drivers of the real exchange rate are the terms of trade, followed by relative factor endowments. Contrary to conventional wisdom, the Balassa-Samuelson effect does not seem to play a significant role in explaining the long-term real appreciation of the Swiss franc. 相似文献

There is increasing recognition that the transfer of foreign technology to developing countries should be considered in light of broader processes of learning, technological capability, formation and industrial development. Previous studies that have looked at this in the context of cleantech industries in emerging economies tend to overlook firm-level specifics. This paper contributes to filling this gap by utilising in-depth qualitative firm-level data to analyse the extent to which the use of different learning mechanisms can explain differences in the accumulation of technological capabilities. This is explored via an examination of eight firms in the biomass power equipment industry in Malaysia during the period 1970–2011. The paper finds that firms relying on a combination of learning from foreign technology partners and internal learning by planned experimentation make most progress in terms of technological capability. Nevertheless, local spill-over effects were found to be important for some firms who learned principally from imitation of local competitors, although significantly, firms learning from local spillovers failed to advance beyond extra basic operating technological capabilities. Those firms who proactively pursued learning from foreign partners, on the other hand, advanced further, reaching basic innovative levels of technological capabilities. These findings are relevant for a wider range of industrial sectors in emerging economies. 相似文献

This paper considers alternative measures of a country's trading gains, i.e., the extra income that it earns (or loses) as the result of changes in the relative prices relevant for international trade, and which makes up the difference between real gross domestic product (GDP) and real gross domestic income (GDI). Looking at both the Laspeyres and the Törnqvist aggregation, we show that the trading gains really consist of two components, a terms-of-trade effect and a real-exchange-rate effect. Nearly all national statistical agencies, receiving no firm guidance from international organizations in this matter, merely consider the first effect, which suggests that the so-called trading-gain estimates they publish are incomplete and misnamed. Even more seriously, it implies that the corresponding measures of real GDI they derive are conceptually flawed. A straightforward way to circumvent these difficulties is to use the gross domestic final expenditure price index as deflator when computing real GDI and the trading gains. Some numerical estimates for Australia are provided as an illustration. The paper also identifies the underlying linear and Translog real GDI functions for which the Laspeyres and Törnqvist terms-of-trade and real-exchange-rate effects are exact. 相似文献
