We develop a hybrid algorithm using Genetic Algorithms (GA) and Simulated Annealing (SA) to solve multi-objective step function maximization problems. We then apply the algorithm to a specific economic problem which is taken out of the corporate governance literature

In Brazil, generous public sector pensions have induced civil servants to retire on average at age 55. In this paper we use an OLG model to assess the effects of such policy induced early retirement on capital accumulation and long-run income levels. We calibrate the model to data from Brazil...

We construct a dynamic model of a small open economy to analyze the effects of large energy subsidies. The model includes domestic energy production and consumption, trade in energy at world market prices, as well as private and public sector production. The model is calibrated to Egypt and used...

Manufacturing enterprises are faced with an increasing global competition and dynamic markets. This development results in a need for more flexible manufacturing structures and the ability for global collaboration. In the curse of this, cross-functional information systems turn into an essential...

Methods for enterprise modelling usually offer limited support for the description of logistical aspects. The paper at hand presents a concept for modelling supply chains in the context of enterprise modelling. This concept, called transportation channel, is part of a resource modelling language...

We study the macroeconomic and welfare effects of decumulating government debt in an overlapping generations model with skill heterogeneity and productive and non-productive government programs. Our results are: First, in the small open economy model calibrated to Greece, the spending-based...
