Standard merger simulations focus solely on price changes while constraining the set of product characteristics to be identical preand post-merger. Recent papers have begun to address this issue (see, e.g. Fan, August 2013 AER). To overcome the limitations of traditional simulations, I endogenize both prices and product characteristics by specifying a two-stage oligopoly game. After estimating ...

From a four-year longitudinal study of 333 stores of a large retailer, we show that increasing product variety and inventory level per product is associated with an increase in misplaced products. We also show that increasing misplaced products at a store is associated with a decrease in store sales. Hence, we highlight a consequence of increased product variety and inventory level per product ...

In this paper, the performance of a CNT-JLTFET under different values of torsional strains of 0, 3, and 5 degrees has been investigated. Simulation has been carried out using non-equilibrium Green’s function (NEGF) formalism in the mode-space approach and in the ballistic limit. The simulation results indicate that, under torsional strain, an increase occurs in the energy band-gap, and thus the...

pistachio nut (pistacia vera l.) is one of the most delicious and nutritious nuts in the world. in order to increase the added value of the pistachio nuts, it is necessary to develop new products to meet consumer needs. this is the first paper on pistachio halva. the product was developed using pistachio paste (as main ingredient), mixture of sugar-glucose, egg white and citric acid. the effect...

Dominating markets with a single product is increasingly difficult, and instead numerous industries are evolving towards mass customization, meaning the production of individually customized and highly varied products or services (Pine, 1993). This proliferation of models allows consumers to find a product that best suits their individual needs. The need for increasing product variety and short...

This experiment was conducted to study the effects of whole yeast (Pichia guilliermondii; CitriStim, ADM, Quincy, IL) cell product supplementation on cecal microflora population and intestinal immune parameters in broilers. In the first experiment, birds were fed 0, 0.1, or 0.2% yeast cell wall product for 42 d. Feeding yeast cell wall products decreased (P = 0.03) the proportion of Escherichia...

it is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future’s demand and their quality and quantity does not change during that period. nevertheless there are special kinds of products which deteriorate or become unusable (such as food products, alcohol, medicines, etc.). therefore if the rate of deterioration is significantly high, the imp...
