We develop a model of household demand for frequently purchased consumer goods that are branded, storable and subject to stochastic price fluctuations. Our framework accounts for how inventories and expectations of future prices affect current period purchase decisions. We estimate our model using scanner data for the ketchup category. Our results indicate that price expectations and the nature...

B options allow bidders to instantly purchase at a specified price an item listed for sale through an online auction. A temporary buyout option disappears once a regular bid is submitted, whereas a permanent option remains available until it is exercised or the auction ends. Such buyout price may be static and remain constant throughout the auction, or dynamic and vary as the auction progresses...

A temporary-equilibrium model replicating institutional features of low-income agricultural economies is developed. In this model, food is held as an asset; because food production is relatively volatile, those with negative temporary income are net buyers of food. When food is the only asset, asset effects are likely to reduce the price-elasticity of the demand for food and can make it tatonne...

This paper develops a two-period disequilibrium model of a small open economy under Keynesian unemployment to analyse the effects of temporary, anticipated, and permanent coffee price shocks. The model includes a government sector that administers a commodity price stabilisation fund, and allows for capital market imperfections. The type of capital market imperfection makes an important differe...

In this study, the effect of a temporary price discount for a larger order than the regular order offered by the supplier on the retailer’s ordering policy is studied. The demand is assumed to be stock-dependent. The units in inventory deteriorate at a constant rate. This study will help the retailer to take the decision whether to adopt a regular or special order policy. The optimum special qu...
