Theoretically based on the Haavelmo theorem, this study analyses the economic effects that increasing public expenditure or reducing public income have on the gross domestic product of Germany, with the help of two medium-sized macro-econometric models, the RWI business cycle model and the Econometric Model of the German Economy. The major finding is that most of the public revenue multipliers are considerably lower than most of the public spending multipliers. However, both the dimension and the time course of the effects are a function of the specific kind of politico-economic measures taken by the government. 相似文献

A windfall in a developing economy with capital scarcity and investment adjustment costs facing a temporary windfall should be used to give more consumption to poorer present generations and to speed up development by ramping up public investment and paying off debt taking due account of the increasing inefficiency as investment gets ramped up. The optimal strategy requires negative genuine saving; the permanent income requires zero genuine saving. The optimal real consumption increments are smaller once one allows for absorption constraints resulting from Dutch disease and sluggish adjustment of ‘home-grown’ public capital. 相似文献

Abstract This paper describes a statistical investigation of observed loss ratios and run-offs for a number of Swedish insurance companies within different lines of business. The main aim of the investigation was to revise existing upper limits for allocation to the so-called safety reserve, which is an untaxed contingency reserve. The effort was successful in that new rules were established by the Swedish Supervisory Authority in accordance with the results of the investigation. This paper also contains an exposition of the general principles underlying the Swedish safety reserve. 相似文献

While research and development (R&D) investment has been procyclical in the post-war period, recent literature suggests that
the optimal path for R&D is countercyclical, and that the economy would be better off by subsidizing R&D in recessions. The
objective of this paper is to analyze the welfare effects of distortions in the intertemporal allocation of R&D resources
and to compare diverse policy interventions so as to improve social welfare. To this end, we introduce a calibrated dynamic
stochastic general equilibrium model with Schumpeterian endogenous growth that is capable of explaining the observed procyclicality
of R&D. Our results show that the cost of business cycles is lower in the decentralized economy with procyclical R&D than
in the efficient allocation with countercyclical R&D. This is because the suboptimal propagation of shocks in the decentralized
equilibrium offsets some of the existing steady-state distortions. In this second-best context, countercyclical R&D subsidies have no positive effect on welfare. In contrast, fiscal policies aimed at restoring
the optimal steady-state produce large welfare gains. 相似文献

We report on an experiment conducted to evaluate the effects of varying the way in which market information is presented to
participants in laboratory Cournot duopolies. We find that the most standard variations, which are the use of a profit table
or a profit calculator, yield indistinguishable performance. However, the addition of a best-response option to the profit
calculator tends to increase aggregate output to the Cournot level and decrease the incidence of tacit collusion. 相似文献

This paper aims to identify some factors that may be explaining differences among secondary students in start-up intentions.
For that, the study develops an entrepreneurial intention model sustained by the use of Azjen’s Theory of Planned Behaviour
(TBP). Using a sample of students aged between 14 and 15 years old, a questionnaire based on the Li?án and Chen’s Entrepreneurial
Intention Questionnaire was administrated. The purpose is to test a model of entrepreneurial intention using structural equations.
The findings point that TPB is an appropriate tool to model the development of entrepreneurial intention through pedagogical
processes and learning contexts. The education and training should centre itself much more in changing personal attitudes
than in knowledge. Moreover, it is desirable that an entrepreneurship educational programme could contribute to the development
of competences related to entrepreneurship, social and civic skills, and cultural awareness. 相似文献

In this paper, we take up an approach of (Lindberg, in Bernoulli, 15(2):464–474, 2009) who introduced a new parameterization
of the Black–Scholes model that allows for an easy solution of the continuous-time Markowitz mean-variance problem. We generalize
the results of (Lindberg, in Bernoulli, 15(2):464–474, 2009) to a jump-diffusion market setting and slightly correct the proof
and the assertion of the main result. Further, we demonstrate the implications of the Lindberg parameterization for the stock
price drift vector in different market settings, analyse the dependence of the optimal portfolio from jump and diffusion risk
and finally indicate how to use the method. We particularly also show how the optimal strategy can be obtained with the restricted
use of historical data. 相似文献
