Abstract: | We present a new algorithm for continuous, nonlinear or linear, and constrained or unconstrained optimization. After proving its convergence, we apply it to unconstrained and constrained maximum likelihood estimation, and compare its performance to that of the Newton-Raphson algorithm. |

Abstract: | This paper quantifies the macroeconomic impacts of the Clean Development Mechanism (CDM) under the Kyoto Protocol based on a computable general equilibrium (CGE) model of international trade and energy use. Employing project-based CDM supply data we assess the relative importance of transaction costs and investment risks as well as CDM regulations through supplementarity and additionality criteria. Our numerical results show that the macroeconomic impacts of transaction costs and investment risks are negligible: Given the large supply of cheap project-based emissions credits in developing countries, compliance to the Kyoto Protocol can be achieved at a very low cost. However, regulatory restrictions such as a supplementarity criterion can substantially curtail the potential efficiency gains from where-flexibility in climate policy. |

Abstract: | This paper analyses the accuracy of replicating portfolio methods in predicting asset prices. In a two-period, general equilibrium model with incomplete financial markets and heterogeneous agents, a computational study is conducted under various distributional assumptions. We focus on the price of a call option on an underlying risky asset. There is evidence that the value of the (approximate) replicating portfolio is a good approximation for the general equilibrium price for CRRA preferences, but not for CARA preferences. Furthermore, there is strong evidence that the introduction of the call option reduces market incompleteness and that the price of the underlying asset is unchanged. There is, however, inconclusive evidence on whether the availability of the option increases agents' welfare. |

Abstract: | In this paper, we try to promote the building of a Quantitative Austrian Modelling (QAM). QAM must be viewed as a complementary quantitative prolongation of the Austrian methods and as a complementary approach to the already existing quantitative approaches - especially we would like here to answer to the appeal of Prof. N.J.Vriend [61]. As we explain it in the first part, our approach resulted from a critical view of the econometric procedures by Austrian methods and, from a theoretical instrumental study of the econometric models. We define the main properties to quantitative approaches and especially to the QAM. In the second part, we present QAM principles and equations (of the AUSTRIAN model), and justify it according to the classical Austrian point of view. The QAM could be viewed as an answer to Prof. M.J.Rizzo [49] about the relationship between the Praxeology and the Econometrics. Indeed, according to its properties, even if QAM won't be able to recreate any observable data, it could give a consistent pattern where the other quantitative approaches could fit. Especially, QAM could help, we hope so, to answer the question we asked about the quality of the econometric behavioral equations [8], in providing two levels of data, from where we could extract a relationship useful to correct observable econometric data. QAM is in building. |

Abstract: | In the focus of the research on regional innovation systems (RIS) is an interaction pattern of different regional agents and institutions on one side and an observation of regional outcomes (in terms of value added, employment etc.) attributed to the aforementioned interaction pattern on the other side. Neither how this interaction pattern comes about nor how this pattern generates the attributed regional outcome is usually investigated more closely. In this article we try to fill this gap in the research about RIS. In section II we specify the two focal points of the literature about RIS and the resulting research gap to bridge. In section III it is shown how input-output tables (IOT) can be used to map the regional interaction dynamics on the level of branches. This is supplemented by an agent-based modelling of the final demand dynamics resulting from the innovation activities of regional agents (section IV). Finally some conclusions for further research are drawn (section V). |
