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.

What goods to export and where to sell them? Our research was pursuing these two major goals. The first one is related to detecting countries where Austria has good perspectives for boosting its export. The basic idea was to use macroeconomic data set detecting the significant variables. We...

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 use an OLG model to study the effects of the generous public sector pension system in Brazil. In our model there are two types of workers, one working in the private sector, the other working in the public sector. Public workers produce infrastructure or education services. We find that...

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...

We investigate whether late redistribution programs that can be targeted toward low income families, but that may distort savings decisions, can “dominate” early redistribution programs that cannot be targeted as a result of information constraints. We use simple two-period overlapping...

We formulate an overlapping generations model with skill heterogeneity and productive and non-productive government programs to study the macroeconomic and intergenerational welfare effects caused by risk premium shocks and government debt reductions. We demonstrate that in a small open economy...

We explore the determinants of inspection outcomes across 1.6 million Occupational Safety and Health Agency (OSHA) audits from 1990 through 2010. We find that discretion in enforcement differs in state and federally conducted inspections. State agencies are more sensitive to local economic...
