Empirical evidence suggests that poorer countries have larger portions of predation. We formulate a neoclassical growth model in which agents devote time either to produce or predate. When the elasticity of substitution between labor and capital is lower than one, the labor share rises with...

The socially optimal allocation has been regarded to be unspecifiable because of utility’s interpersonal incomparability, Arrow’s general possibility theorem, and other factors. This paper examines this problem by focusing not on the social welfare function but instead on the utility...

This paper examines the socially optimal allocation by focusing not on the social welfare function but instead on the utility possibility frontier in exogenous growth models with a heterogeneous population. A unique balanced growth path was found on which all of the optimality conditions of all...

This paper analyzes, within its feasible parameter space, the dynamics of the Uzawa-Lucas endogenous growth model. The model is solved from a centralized social planner perspective as well as in the model’s decentralized market economy form. We examine the stability properties of both versions...

This contribution concerns models and theories of structural economic dynamics. The theories and models analyzed in the paper follow two different approaches, circular and vertical, in the analysis of structural dynamics. The content of this contribution is essentially methodological. This work...

In this paper the results of testing the causal interdependences between the gross fixed capital formation and GDP in Poland are presented. Some recent theoretical deliberations (like alternative method of testing for direction and sign of long run causality) and econometric tests (bootstrap...

This paper shows that the results of Bianco (2006) depend critically on the assumption that there are no difference between the intermediate goods share in final output, the returns of specialization and the degree of market power of monopolistic competitors. In this paper, we disentangle the...

Starting in the early 1980s, the U.S. patent regime experienced major changes that allowed the patenting of numerous scientific findings lacking in current commercial applications. We assess the rationality of these changes in the legal and institutional environment for science and technology...

This paper studies the Pareto-optimality of the consensual optimum established in "Allais-anonymity as an alternative to the discounted-sum criterion I: consensual optimality" (Mabrouk 2006a). For that, a Pareto-optimality criterion is set up by the application of the generalized Karush, Kuhn...

Using sectoral growth accounting techniques from a structural perspective à la Lewis, the paper analyzes the structural determinants of labour productivity in Asia and Latin America, indicating a contrasted situation between both developing regions. While Asia appears to be engaged in a...
