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...

In ‘Comments on Theeuwes and Riemersma’s Revisit of Daytime Running Lights’ Williams and Farmer ( 1996) comment on a paper we published in Accident Analysis and Prevention. In this paper we show that the original claim by Andersson and Nilsson ( 198 1) that the nationwide implementation of Daytime Running Lights (DRL) in Sweden resulted in a reduction of multiple daytime accidents was not warra...

Agricultural extension has shifted towards community-centric, farmer-centered, and participatory approaches that enhance rural change through a social learning lens, resulting in the emergence of farmer-to-farmer model. The purpose study was to understand lead farmer selection criteria within model their impacts on community learning. We applied Torraco’s (2005) integrative literature review me...
