In this paper, a two sector economic economic growth model with renewable natural capital is developed. The model is similar in spirit to the models of Solow (1974) and Hartwick (1977) but with a slightly di erent emphasis. Namely, address the role human behavior and culture plays in the dynamics of a human ecological economic system. The analysis of the model indicates that there are both lowe...

This paper considers the effects of corruption and government spending on economic growth. It starts from an endogenous growth model and extends it to account for the detrimental effects of corruption on the potentially productive components of government spending, namely military and investment spending.

The paper is devoted to a variety of solutions aiming at taking time into account in economic and managerial analyses. It presents an example of a decision problem – namely the analysis of economic environment and of barriers to entry to a market space. Next, it shows how time can be treated in intelligent decision systems, in context of temporal knowledge representation and temporal reasoning.

Representation and modeling of economic uncertainty is addressed by different modeling methods, namely stochastic variables and probabilities, interval analysis, and fuzzy numbers, in particular triple estimates. Fo-cusing on discounted cash flow analysis numerical results are presented, comparisons are made between alter-native modeling methods, and characteristics of the methods are discussed.

This article describes the principal uses of the data collected in the Economic Census. Namely, the data serve as a framework and statistical benchmark for current economic surveys; as source data for calculating composite measures of the nation’s economy; and as the basis for planning and monitoring of national, state, and local economic policies and programs. The data also are used for resear...
