Research and development has always played a strategically important role in the survival and the growth of technology-based firms. R&D is positively linked to company performance measures such as sales, productivity and shareholder returns and in addition to this, facing increased competition,...

Economic simulation - as economic pattern simulation use - which is already a useful tool of searchers and managers, would be a tool of economic teacher. When teacher want explain economic theories, he can't do experiment, hence simulation would take place experiment. Simulation is an analytical...

The purpose of this paper is, through a system of software, to analyze some theoretical aggregate models. We suggest to build a disaggregated model to compare its results with these of the aggregated one. The disaggregated model uses an analogical mechanism of the individual behaviors so that a...

This paper examines the performance of prediction intervals based on bootstrap for threshold autoregressive models. We consider four bootstrap methods to account for the variability of estimates, correct the small-sample bias of autoregressive coefficients and allow for heterogeneous errors....

An optimal asset allocation is crucial for non-life insurance companies. The most previous studies focused on this topic use a mono-objective technique optimization. This technique usually allows the maximization of shareholders’ expected utility. As non-life insurance company is a complex...

This study presents some quantitative evidence from a number of simulation experiments on the accuracy of the productivity growth estimates derived from growth accounting (GA) and frontier-based methods (namely Data envelopment Analysis-, Corrected ordinary least squares-, and Stochastic...

Markov chain theory is proving to be a powerful approach to bootstrap highly nonlinear time series. In this work we provide a method to estimate the memory of a Markov chain (i.e. its order) and to identify its relevant states. In particular the choice of memory lags and the aggregation of...

We analyze a model in which agents’ decisions to enter or exit investments are influenced from their individual and external parties’ transaction histories. Actual investment outcomes are unknown to all participants until the end of decision periods, but outcomes do change depending on the...
