Zusammenfassung Aufgrund der derzeitigen Finanz- und Wirtschaftskrise wird die Verschuldung der ?ffentlichen Haushalte in diesem und dem kommenden
Jahr so erheblich steigen, dass es selbst unter günstigen gesamt- und finanzwirtschaftlichen Rahmenbedingungen mindestens
ein Jahrzehnt dauern k?nnte, bis Deutschland wieder beide Verschuldungsgrenzen des Maastricht-Vertrages einhalten wird. Wie
rasch kann die hohe Staatsschuldenquote zurückgeführt werden? Welchen Beitrag kann die Finanzpolitik für ein angemessenes
Wirtschaftswachstum leisten? Wie sollte die Konsolidierungsstrategie ausgerichtet sein?

While the energy generation system is changing towards the use of more renewable energies, the problem of how to deal with fluctuating energy supply is increasing. Smart appliances in households are often referenced as one possible solution, as their operation may be shifted in time and, thus, used to balance an unstable energy supply. The potential of such appliances has been studied to date mainly in pilot installations with a very limited number of participants or by making assumptions on what might be possible. With this work, a semi‐representative approach for 12 European countries was used to assess actual consumer habits for the use of washing machines and dishwashers which then could be used to calculate average load profiles for those appliances depending on the time of the day. Using these profiles, it is strait forward to calculate how much load may be shifted by those appliances in a demand response application. This allows aggregators or energy utilities to assign clear financial benefits to the shifting potential of those appliances. Consumers use the shifting of appliance operation already today for various reasons. Investigating these reasons allows to learn already a lot about the flexibility of consumers. 相似文献

This paper unites elements of Sidrauski's (1967) monetary model of growth, Ventura's (1997) analysis of the effects of international trade on growth, and some work on the labour market implications of growth by Barro and Sala-i-Martin (1995). It was shown by Ventura that, for a small economy, free international trade leads to an increase of the de facto elasticity of substitution between the domestic factors of production. The first part of the paper analyses how such an increase in the elasticity of substitution influences the steady state and the speed of convergence. From the Sidrauski model we know that money is super-neutral in the long-run but that monetary policy can have real effects along the transition path as long as the intertemporal elasticity of substitution is not equal to one. In the second part of this paper, it is shown how these results also depend on the elasticity of substitution between factors of production. The results give some important insights into possible interactions between monetary and trade policy in the long and short run. The last part of the paper deals with a modified version of the monetary growth model, which includes endogenous labour supply as in Klump (1993) or Barro and Sala-i-Martin (1995). In this context, international trade, by increasing the elasticity of substitution, leads to lower domestic employment in the long run whereas monetary policy may be able to increase employment at least in the short run. Thus, under certain circumstances, trade and monetary policy can be regarded as complementary with respect to their labour market effects. 相似文献

In this paper we analyze a stochastic dynamic advertising and pricing model with isoelastic demand. The state space is discrete, time is continuous and the planing horizon is allowed to be finite or infinite. A dynamic version of the Dorfman–Steiner identity will be derived. Explicit expressions of the optimal advertising and pricing policies, of the value function and of the optimal advertising expenditures will be given. The general results will be used to analyze the case of impatient customers. Furthermore, particular time inhomogeneous models and homogeneous ones with and without discounting will be examined. We will study the social efficiency of a monopolist's optimal policies and the consequences of specific subsidies. From a buyer's perspective, our analysis reveals that waiting – when looking at (immediate) expected prices – is never profitable should two or more units be available. But we will also prove that the sequence of average sales prices is monotone decreasing. Moreover, the techniques applied to solve the discrete stochastic advertising and pricing problem will be used to solve a related deterministic control problem with continuous state space. 相似文献

Using a new data set for 41 German non‐governmental organisations (NGOs), we analyse the allocation of NGO aid across recipient countries in a Tobit regression framework. By identifying for each NGO the degree of official financing, we address the largely unresolved issue of whether financial dependence on the government impairs the targeting of NGO aid. It turns out that German NGOs are more active in poorer countries, while they do not complement official aid by working under difficult local conditions. Beyond a certain threshold, rising financial dependence weakens their poverty orientation and provides an incentive to engage in ‘easier’ environments. In addition, we find that the NGOs follow the state as well as NGO peers when allocating aid. This herding behaviour is, however, hardly affected by the degree of official financing. 相似文献

Aktivierende, therapeutische und rehabilitative Pflege - Das Bild der Pflege in der Geriatrie hat sich in den letzten Jahren
deutlich gewandelt. Denn die Entwicklung verl?uft dynamisch: von einem Assistenzberuf für ?rzte hin zu einer Berufsgruppe,
die wesentliche Akzente für die Gesundheitsversorgung in eigener Regie setzt. 相似文献

Using a unique survey data on agricultural traders in China in 2004, this study provides direct evidence on the significance of inter-regional trade barriers and their key components. Our major findings are as follows. (1) The trade barriers within China are fairly small, accounting for about 20% of trade value. (2) Transport and non-transport costs respectively contribute 42% and 58% to the trade barriers. (3) Labor and transport-related taxes are the two largest proportions of total transport costs, and respectively account for 35% and 30%. (4) Artificial trade barriers created by the government are not sizable as we perceived. (5) Road quality is crucial for reducing transport costs within China: increasing transport speed by 1 km per hour, the total transport costs for Chinese agricultural traders would decrease by 0.6%, mainly due to improved fuel-burning efficiency and reduced labor requirement. 相似文献
