This paper has investigated the determinants of total consumer credit for the USA over the period 1968:Q1 to 2011:Q3. Using Breitung's (2001) non-parametric rank tests, we find the existence of linear cointegrating relationships in the consumer credit models. Enders and Siklos' (2001) threshold...

This paper presents the surrogate model based algorithm SO-I for solving purely integer optimization problems that have computationally expensive black-box objective functions and that may have computationally expensive constraints. The algorithm was developed for solving global optimization...

The author of this paper analyses examples of network diagrams presenting different projects. The target consists in compressing the project schedule to a time desired and minimizing direct costs. On the basis of these case studies the author shows how both, i.e., 1) the algorithm based on the...

This paper considers the forecasting performance of a nonlinear dynamic stochastic general equilibrium (DSGE) model. The results are compared to a wide selection of competing models, which include a linear DSGE model and a variety of vector autoregressive (VAR) models. The parameters in the VAR...
