Estimate of Armington substitution elasticity for fishery products in Iran
Abstract Nowadays, fishery and aquaculture products form an important fraction of the protein requirement and food of many people on the earth. The hike in prices of these essential products seems necessary owing to the increase in demand and consumption of these products in the country. The price transmission from the international market to the domestic market of tunas was investigated in t...
متن کاملEstimate of Armington substitution elasticity for fishery products in Iran
The price transmission from the international market to the domestic market of tunas was investigated in the present research. For this purpose, the elasticity of substitution between tuna imports with goods produced in Iran (Armington Elasticity) was calculated. Armington elasticity reflects a degree of substitution between commodities produced domestically and those produced abroad. A greater...
متن کاملIntertemporal Substitution and Storable Products
Storable products allow consumers to time their purchases to exploit price fluctuations. It has been documented that during promotions consumers buy more. The additional purchases are potentially intended not only for current use, but to be stockpiled for future consumption. This paper discusses the predictions of a consumer inventory model and reviews the available evidence. We then discuss th...
متن کاملPricing Policies for Perishable Products with Demand Substitution
This paper studies optimal pricing policies for a family of substitute perishable products with demand correlation. Potential buyers arrive according to an exogenous stochastic Poisson process. At each demand epoch, the arriving customer observes the set of substitute products for which there is still inventory available together with their corresponding prices. Based on this information, the c...
متن کاملThe stereochemistry at carbon 3 of pyruvate lyase condensation products. Aldolases forming condensation products racemic at carbon 4.
Both the Schiff base-mediated 2-keto-4-hydroxyglutarate aldolase of liver and the metal-activated a-keto-/3-deoxyhexarate aldolase of Escherichia coli condense pyruvate and glyoxylate to form (4-RS)-Z-keto-4-hydroxyglutarate. Both enzymes catalyzed a condensation between [3-3H3]pyruvate and glyoxylate. It was found that C-C synthesis occurred 6 to 7 times faster than C-T bond cleavage. Thus, py...
