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 article studies the relationship between the off-farm participation behavior of farm operators and their spouses and the demographic composition of the household. I focus on farm families without parents, siblings or partners, and examine the effects of the existence of elderly children of...

The rapid increase in adult mortality due to the AIDS epidemic in sub- Saharan Africa raises great concern about its impact on child welfare. This article estimates the impact of AIDS-related adult mortality on primary school attendance in rural Kenya using a panel of 1,266 households surveyed...

We apply the set up of limited commitment model to empirically test the role of informal risk-sharing networks using panel data on informal credit transactions from rural Ethiopia. The empirical estimates provide convincing evidence for the belief that enforcement problem limits the direct role...

Economic hardship, agricultural policy reform and price developments have adversely affected incomes from agricultural production in Lithuania, and many farm households have accessed additional sources of income in the rural economy. In an analysis of recently collected survey data we find that...
