The transition from central planning to a market economy: A computable general equilibrium model

This paper develops a computable general equilibrium (CGE) model of the transition from a central planned economy to a market economy. The model is an extension of Wellisz and Findlay's (1986) model of the Soviet second economy. By distinguishing alternative assumptions about the disposition of the government budget, two model variants — the activist and non-activist — are analyzed. Equilibria of these model variants are computed for various parameter specifications of the Kantorovich ray, which represents the stringency of central planners' direction of the economy. The paper shows that increasing efficiency of the private sector, while it reduces the size of government subsidies to the state sector, does not necessarily increase the net government budget.     

Electricity spot price modelling with a view towards extreme spike risk

Sums of Lévy-driven Ornstein–Uhlenbeck processes are appropriate for modelling electricity spot price data. In this paper we present a new estimation method with particular emphasis on capturing the high peaks, which is one of the stylized features of such data. After introducing our method we show it at work for the EEX Phelix Base electricity price index. We also present a small simulation study to demonstrate the performance of our estimation procedure.     

Die stochastische Modellierung von Großschäden für den Einsatz in internen Risikomodellen der Schadenversicherung

Along with individual corporate management and regulatory matters for instance within EU regime Solvency II, Internal Risk Models are very important for major general insurance companies. Of crucial importance in building these internal models, is the stochastic modelling of large claims and in particular, the selection and parameterization of suitable probability distributions for the amount and number of claims based on empirical data. To this end, in practice, a visually-based methodology is more appropriate and workable than strict mathematical approaches. Based on a practical case study, this paper provides some insight into a visually-based methodology for internal risk models.     

中国刻意“转型”珠三角愁云惨淡

【德国之声8月1日】珠江三角洲转眼间上万企业倒闭，香港业界一片愁云。连阿迪达斯这样的世界名牌也在局部撤离中国。中国变贵了，劳动密集型产业纷纷撤出。但中国政府对此似乎并不在乎，似乎在有意地“转型”。     

HEATH–JARROW–MORTON INTEREST RATE DYNAMICS AND APPROXIMATELY CONSISTENT FORWARD RATE CURVES

We study a finite-dimensional approach to the Heath–Jarrow–Morton model for interest rate and introduce a notion of approximate consistency for a family of functions in a deterministic and stochastic framework. This amounts to asking the decrease of the minimum distance in least squares sense. We start from a general linearly parameterized set of functions and extend the theory to a nonlinear Nelson–Siegel family. Necessary and sufficient condition to have approximately consistency are given as well as a criterion of stability for the approximation.     

Deterrence, Lawsuits, and Litigation Outcomes Under Court Errors

This article presents a strategic model of liability and litigationunder court errors. Our framework allows for endogenous choiceof level of care and endogenous likelihood of filing and disputes.We derive sufficient conditions for a unique universally divinemixed-strategy perfect Bayesian equilibrium under low courterrors. In this equilibrium, some defendants choose to be grosslynegligent; some cases are filed; and some lawsuits are dropped,some are resolved out of court, and some go to trial. We findthat court errors in the size of the award, as well as damagecaps and split awards, reduce the likelihood of trial but increasefiling and reduce the deterrence effect of punitive damages.We derive conditions under which the adoption of the Englishrule for allocating legal costs reduces filing.
