This paper presents new results of mathematical modeling of economy and environment interaction. A model of mutual interaction of livestock farming - one in a two main agricultural branches - and natural pastures that are the essential part of livestock farming forage reserve is proposed....

This paper introduces a dynamic model of productivity measurement based on recent endogenous growth theories. The model presented in this study is based on dynamic duality theory and incorporate public goods (public capital and R&D) as external factors to the firms. It also rationalizes the...

A flexible production function analysis is addressed to Namibia's data for the 1968-1992 period to test for evidence of structural problems in sectoral and sub-sectoral performance. The analysis found the primary sector to be characterized by constant returns to scale through the entire 25...

This paper presents experimental evidence about how individuals learn from information that comes from inside versus outside their ethnic group. In the experiment, Thai subjects observed information that came from Americans and other Thais that they could use to help them answer a series of...

This paper analyses, within the new growth theory framework and using panel cointegration techniques, the effect of agricultural international technological spillovers on total factor productivity growth for a sample of 47 countries during the period 1970-1992. The analysis shows that total...

The institution of slavery displays a puzzling historical pattern: it is found mostly at intermediate stages of agricultural development, in horticultural societies, and less frequently among hunter-gatherers and societies at more advanced agrarian stages. We explain this rise-and- fall pattern...

This work builds a macro model for livestock farming based on aggregation of initial micro description for rational control of total number of vintage livestock (age cohorts). All variety of animal kinds is reduced to one by given recount coefficients. An optimal problem on co-hort total number...

Natural resources in sub-Saharan Africa suffer from a bad reputation. Oil and diamonds, particularly, have been blamed for a number of Africa’s illnesses such as poverty, corruption, dictatorship and war. This paper outlines the different areas and transmission channels of how this so-called...

Although the core model of the Dutch Disease makes unambiguous predictions regarding the negative effect of a resource boom on a country’s manufacturing exports, the empirical literature that has followed has not clearly identified this effect. I attribute this to the failure of the existing...
