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

In this paper, we study different and, in particular, “optimal” reactions of fiscal (and to some extent monetary) policies
to the financial and economic crisis of 2007–2009 in Slovenia, a small open economy that is part of the Economic and Monetary
Union (EMU). Using an econometric model of the Slovenian economy, we simulate the effects of the global crisis under the assumption
of no-policy reactions, i.e. assuming that macroeconomic policies are conducted without attempting to deal with the effects
of the crisis. Next, we study the possibilities of fiscal policy reducing or even annihilating the effects of the crisis.
We also investigate the optimal reaction of fiscal policies based on the assumption that Slovenian policy-makers behave as
though they were optimizing an objective function. We show that optimal policies call for only a very modestly active countercyclical
role of fiscal policies. There are strong trade-offs between countercyclical fiscal policies and the requirements of fiscal
solvency. 相似文献

This paper studies the impacts of income distribution on the efficiency of trade mechanism and rationing of agents who are priced out of trade in a dynamic search model with two-sided asymmetric information. Buyers and sellers have asymmetric information about valuations and incomes respectively. In such a frictional environment, the effects of several variants of changes in income distribution on efficiency of trading mechanism and the population of rationed buyers and sellers are elaborated. 相似文献

Peter Boettke (2007) argues that economists need not act pluralistically in order for pluralism to thrive in the marketplace of economic ideas. From a market process perspective, Boettke sees intellectual diversity and openness as catallactic outputs, not inputs—emergent by-products of academic specialization and trade. To expect individual scholars to behave in a pluralistic manner is unnecessary and “completely inappropriate” since it detracts from their central task: “to commit themselves to an approach and pursue it doggedly, even in the face of great doubt and resistance by one’s peers” (Boettke 2007). This paper proposes a Smithian revision of Boettke’s position. The author argues that scholarly pluralism is best understood as a constitutional rule of academic life—a virtue ethic that promotes learning and intellectual freedom by mitigating tyranny and autarky in the republic of science. Drawing from the writings of Adam Smith, Friedrich Hayek, Deirdre McCloskey, Bruce Caldwell, James Buchanan, Don Lavoie, and Boettke himself, the author argues that scholarly pluralism has been, and continues to be, a necessary condition for the flourishing of Austrian economists as free, responsible, efficacious thinkers. 相似文献

Wohnungsdesorganisation bei Sucht - Chaotische Wohnverh?ltnisse lassen sich oft auf eine Suchterkrankung zurückführen. Dabei
kann man einen deutlichen Unterschied zwischen Wohnungen von Menschen mit einer Kaufsucht und denen von Menschen mit psychischen
St?rungen und Verhaltensst?rungen durch psychotrope Substanzen beobachten. 相似文献
