We propose a method to estimate both whether there is an overall infrastructure shortage and the optimal share of infrastructure in gross fixed capital formation (GFCF). This is based on a two-gap model and linear programming, and is illustrated with the case of Mexico (1950-1985). The results...

This paper investigates the growth impact of Information and Communication Technologies (ICT) in an economy consisting of three sectors: ICT-producing, ICT-using, and non-ICT-using. The ICT progress causes falling prices of the consumption and intermediates produced by the ICT-using sector,...

The topic of alternative price zone configurations is frequently discussed in Central Western Europe where - so far - national borders coincide with borders of price zones. Reconfiguring these price zones is one option in order to improve congestion management, foster trading across borders of...

We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are...

In the recent work of Dempster, Evstigneev and Taksar (2006) it has been shown that the von Neumann-Gale model of economic dynamics can serve as a convenient and natural framework for the analysis of questions of asset pricing and hedging under transaction costs. The present article focuses on a...

Paper introduces mathematical models describing long-time effects of real savings on economic growth. Models are built for single-product and multiple-product economy with market forces presented through the system of ordinary differential equations. Modeling results show a limited long-run...

Public health implications of COVID-19 resulted in widespread business closures and job losses. Disruptions in the service and transportation sectors, acute reductions in income, and an uptick in unemployment were the outcome of pandemic mitigating procedures adopted by many governments. While...

Cross-sector labor reallocation is associated with costs at the micro level ranging from the costs of geographical relocation and skill change/adaptation to unemployment. We show that monotonous reallocation paths minimize the aggregate reallocation costs in the three-sector framework (relating...

The purpose of this paper is to provide an exact algebraic solution to a fully specified Romer endogenous growth model. The proposed model has three main virtues. First, taking Romer's [1986] model as the starting point, we build a completely and explicitly micro-founded competitive general...

This paper explores sufficient conditions for a continuous stationary Markov optimal policy and a concave value function in stochastic dynamic programming problems. Also, the paper addresses conditions needed for the differentiability of the value function. The paper uses conditions such as...
