The existence of farmer groups still cannot be a solution to create change in Palesanggar Village. purpose this study was see the effect training and motivation on development Village, Pegantenan District. This uses an associative research method with multiple linear regression as means analysis. sampling technique carried out by total or saturated samples, sample 74 farmers. results showed tha...

The Branch and Bound (B&B) algorithm is one of the most used methods to solve in an exact way combinatorial optimization problems. In a previous article, we proposed a new approach of the parallel B&B algorithm for distributed systems using the farmer-worker paradigm. However, the new farmer-worker approach has a disadvantage: some nodes of the B&B tree can be explored by several B&B processes....

This paper investigates an important channel through which improved access to market information could increase the prices that producers receive from middlemen. I develop a theoretical model of trade between a farmer and a middleman which allows for the existence of different types of middlemen. The source of heterogeneity is attitudes towards fairness. I provide an empirical test of the theor...

This study considers a quantity discount problem between a single seller (poultry famer) and two buyers (retailers). The poultry farmer’s inventory level increases due to the increase in the weight of the fowls. The retailers purchase fresh chicken meat from the poultry farmer, the inventory levels of the retailers are therefore depleted due to the combined effects of its demand and deteriorati...

This paper uses the old Keynesian representative agent model developed by Roger E. A. Farmer [Expectations, Employment and Prices. New York: Oxford University Press (2010)] to answer two questions: (1) Do increased government purchases crowd out private consumption? (2) Do increased government purchases reduce unemployment? Farmer compared permanent tax-financed expenditure paths and showed tha...

We consider the population dynamics of two competing species sharing the same resource, which is modeled by the carrying capacity term of logistic equation. One species (farmer) increases the carrying capacity in exchange for a decreased survival rate, while the other species (exploiter) does not. As the carrying capacity is shared by both species, farmer is altruistic. The effect of continuous...

The average lifetime of sows as observed in production herds is primarily influenced by management decisions. Usually the farmer decides to cull a sow, either because he expects that a gilt's average productivity is higher than the marginal productivity of the sow, or because the current number of sows exceeds the production capacity, e.g. in the farrowing department. Several studies have shown...

We provide results from a study of two separate sectors within the cotton-growing region of southern Mali. In one sector, farmers have engaged in a farmer field school (FFS) training programme since 2003--the other not. One goal of the training was the adoption of alternatives to the use of hazardous insecticides, through integrated pest management (IPM) methods. Over an 8-year period, analysis...
