abstract the purpose of this paper is estimation of the effective factors on tea supply in gilan province by using time series data during 1360-1390 in the form of nerlove model. according to the results, explanatory variables of the model could describe 97 percent of dependent variable (product supply) changes. the results show that the guaranteed price index of green tea leaf with elasticity ...

This paper develops the Latent Symmetric Elasticity Structure (LSES), a market share price elasticity model which allows elasticities to be decomposed into two components: a symmetric substitution index revealing the strength of competition between brand pairs, and a brand-specific coefficient revealing the overall impact of a brand on its competitors. An application of the model to unconstrain...

Objective To assess how raising cigarette excise taxes in Peru might impact cigarette consumption, and to determine if higher taxes would be regressive. Methods Total demand price elasticity was estimated by income groups using two datasets: quarterly time-series data from 1993 - 2012 and data from a cross-sectional survey of income and expenses conducted in 2008 - 2009 .

The evaluation of the impact of an increase in gasoline tax on demand relies crucially on the estimate of the price elasticity. This paper presents an extended application of the Partially Linear Additive Model (PLAM) to the analysis of gasoline demand using a panel of US households, focusing mainly on the estimation of the price elasticity. Methodologically, we propose a root-n consistent esti...

production subsidies, as a part of the strategy of economic growth of the agricultural sector, are of great importance around the world. subsidizing production inputs, particularly energy input, is another way of directing subsidy to the agricultural sector. in this research, production function of the agricultural sector was estimated using econometric methods and time series data. after calcu...
