In this study the autoregressive distributed lag model and error correction model to estimate Hazard function is used during the years 1377-1394. The results show that in the short term and long term there is substitution between electricity and natural gas in the domestic sector. But the price elasticity of demand relative to the price of electricity is less than 5.0, this result indicates tha...

Fluctuations in crude oil prices are among the factors affecting other economic indicators, and therefore these fluctuations have always been of interest to economists. In this paper, the effect of fundamental market factors (supply and demand of crude oil) on changes in world oil prices is addressed and supply and demand elasticity are estimated using the simultaneous equations system consider...

Do online price estimates directly impact sales prices in the real estate market, and if so, how large is that impact? We develop an estimation model that uses the di↵erence between list prices and online price estimates to proxy for house specific unobservables. To account for neighborhood specific unobservables, we use neighborhood first di↵erencing. Using house price estimates, list prices a...

In addition to the wireless telephone boom, similar exponential increasing trend in wireless data service – short messaging services (SMS) –, is visible, as technology advances. Given these interesting communication trends, we develop a structural model to understand mobile users’ behavior in the individual level consumption of voice and SMS services, allowing for cross-service dependencies. Th...

This paper investigates the relationship between the selling price of diamonds and their weight in carats. For this purpose, we use a unique sample of 112,080 certified diamonds collected from www.info-diamond.com during the first week of July 2011. We find substantial differences in pricing depending on cut shape. The price of diamonds increases markedly with the carat weight, with a price ela...

abstract increase in aquatics demand is one of the major goals for production policies. hence analysis of demand structure and aquatics consumption patterns is very applicative and useful for policy makers. using the almost ideal demand system (a.i.d.s), the demand function for types of aquatics and chicken meat in urban and rural societies in kerman city were estimated. applying time series da...

The sales increase for a brand on promotion could be due to consumers accelerating their purchases (i.e., buying earlier than usual and/or buying more than usual) and/or consumers switching their choice from other brands. Purchase acceleration and brand switching relate to the primary demand and secondar...
