price is one of the four elements of marketing mix. one of the important decisions any business faces is select pricing strategies that can be effective in achieving company goals. pricing methods are generally divided into cost-based and value-based methods. considering that the marginal cost of information goods is zero, the pricing methods of these goods is value-based. in this study, mtn ir...

iran has experienced high food prices in recent years. this paper examines the welfare impacts of rising major food groups' prices on iranian urban households using quadratic almost ideal demand system (quaids) approach. the elasticity coefficients derived from quaids are used to estimate compensated variations (cv).the study uses iranian household expenditure and income survey (heis) raw data,...

This paper provides a unified growth theory, i.e. a model that explains the very long-run economic and demographic development path of industrialized economies, stretching from the pre-industrial era to the present-day and beyond. Making strict use of Malthus’ (1798) so-called preventive check hypothesis – that fertility rates vary inversely with the price of food – the current study offers a n...

liberalization of energy price increases costs of agricultural inputs and costs of agricultural production. all these changes may affect the overall competitiveness of domestic products with similar foreign products. as a result of that, total cost of agricultural products are increased and profitability are decreased. in this paper, energy consumption for producing corn were calculated using c...

There is widespread concern about the effect of the Uruguay Round policy changes on world agricultural prices and consequently upon the welfare of developing countries. Assessing welfare changes with the standard terms of trade effect calculation can be misleading for distorted economies, since the distortion effect operates in addition or in opposition to the terms of trade effect. This study ...

This paper studies second degree price discrimination for information goods. Prior research in the context of traditional goods (where marginal costs are convex as a function of product quality) shows that a firm can increase profits by offering vertically differentiated products to heterogeneous consumers. Some researchers have obtained the converse result for information products, assuming ne...

Energy carriers are one of the most important inputs in the agricultural sector. These inputs have been the foundation of the development and transition of the agricultural sector from the traditional stage to the industrial stage. The energy per capita marginal consumption in Iran’s agricultural sector is 3.2 times greater than its global average. Therefore, it is essential to save and optimal...

ii. Suppose the specific factor model is extended to N goods and (N+1) factors: one factor that is specific to each sector and only one mobile factor (labor). Given this structure, how does an increase in the price of good 1 affect the output of each good and the real return to each factor? Do these results depend on the specification of technology, or would they hold for any model with N goods...
