abstract in order to evaluation the effects of price policies (wheat guarantee price in each period and its price lag), environmental (planted area) and climatic (min and max average temperature, total annual precipitation, cold-day degree and hot-day degree) factors, we considered wheat yield in razavi-khorasan province (9 cities) for a 13-year statistical period (1371-72 to 1383-84). in this ...

We present a structural model of urban growth in a spatial equilibrium setting to aid the separation of the effects of demand shocks from those of the spatial variation in housing supply elasticity. The model is applied to an analysis of urban growth across Chines cities between 1998 and 2004, to evaluate the determinants of housing supply elasticity. The variation in supply, via urban expansio...

According to the standard analysis of commodity prices, stockpiling is a necessary signature of speculation. This paper develops an approach suggesting that speculation may temporarily push crude oil prices above the level justified by physical-market fundamentals, without necessarily resulting in a significant increase in oil inventories. Looking beyond debate on the value of oil-demand price-...

This paper takes a different approach to estimating demand for medical care that uses the negotiated prices between insurers and providers as an instrument. The instrument is viewed as a textbook "cost shifting" instrument that impacts plan offerings, but is unobserved by consumers. The paper finds a price elasticity of demand of around -0.20, matching the elasticity found in the RAND Health In...

BACKGROUND This study uses cigarette price elasticity to evaluate the effect of a new excise tax increase on cigarette consumption and to investigate responses from various types of smokers. METHODS Our sample consisted of current smokers between 17 and 69 years old interviewed during an annual face-to-face survey conducted by Taiwan National Health Research Institutes between 2000 to 2003.

in this paper, using kakwani-son method, price elasticity of poverty is calculated for taxed edible goods in the year 2004. this elasticity shows the total effect of price changes on poverty. the total effect is the sum of redistribution and income effects of price change. in fact, the redistribution effect tells us whether an increase in the price of a commodity hurts the poor more than the ri...

This paper uses a general method of moment regression technique to estimate an energy demand function with a dataset covering 71 countries between 1965 and 2010. The estimated results show that countries undergoing rapid economic growth may show relatively higher income and price elasticities in the long run. The higher income elasticities and lower price elasticity in the short run of rapid gr...
