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...

This study addresses the effects of macroeconomic conditions on the labour market outcomes of immigrants. It simultaneously identifies the separate effects of macro conditions at the time of entry to the labour market and at the time of the survey, while allowing for cohort effects. Also, for...
