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...

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 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). Solution of an optimal problem on cohort total number of livestock gives the age limit for the operation of animals, the...

Legal profession represents a key labor sector whether in politics or business in any developed or underdeveloped country. What resources do lawyers use for matching the demand to their own services’ supply? Private sector lawyers make use of their level of human capital and their social...

Short-term contracts provide weak incentives for durable input investment if post-contract asset transfer is difficult. Our model shows that when both agents provide inputs, optimal contract length balances weak incentives of one agent against the other. This perspective broadens the existing...

This paper examines changes in agricultural productivity in18 developing countries over the period 1961-1985. We use the nonparametric, output- based Mamquist index to examine whether the results from such approach confirm results from other methods that have indicated declining agricultural...

In this paper we propose an empirical model to decompose the evolution of the agricultural GDP share of Taiwan into three components: price changes, factor endowment changes and technological change. The full sample period is 1967 to 1997. The data were first tested to assess whether the time...

This paper examines agricultural policies in 18 developing countries over the period 1961-1985. We measure productivity with both a nonparametric Malmquist index and a production function, confirming previous findings of declining agricultural productivity, but with sufficident inconsistencies...
