‎This paper proposes a multi-supplier multi-product inventory model in which the suppliers have unlimited production capacity, allow delayed payment, and offer either an all-unit or incremental discount. The retailer can delay payment until after they have sold all the units of the purchased product. The retailer’s warehouse is limited, but the surplus can be stored in a rented warehouse at a...

Abstract. We model costly interactions (contracts) between managers and investors. We suggest that globalization of production and favorable technology shock of the 1990s altered economic environment of managerinvestor interactions. These changes exacerbate agency conflict due to the increased managerial gains from ex post reneging, and, simultaneously, decreased costs of managerial reneging. I...

Nutrient management is central in water footprint analyses as it exerts strong control over crop yield and potentially contributes to pollution of freshwater, the so-called grey water footprint. In the frame of grey water footprint accounting, two methods are suggested, the constant leaching fraction approach (10% of applied fertilizer N) and the N surplus approach. We compared both approaches ...

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule does not imply determinacy, nor does it support an efficient outcome. Optimal policies yield a...

Proper corridor configuration is the basic prerequisite for meeting demand to maximum extent and optimally configuring transport resources. As existing studies only pursue quantitative balance, without good understanding of decision-making mechanism passenger travel, they can hardly be used guide effective infrastructure planning. The aim this study was put forward a new planning concept from p...
