Oil price shocks are the main source of macroeconomic fluctuations in oil exporting countries. It is believed that appropriate monetary policy can help to stabilize these unwanted variations toward optimal allocations. A stochastic dynamic general equilibrium model featuring the properties of both cost push and wealth effect transmission channels is developed for the Iranian economy. In thi...

t his study investigates the factors affecting the demand for new residential buildings in urban areas of iran during 1976-2010. the demand function for new residential buildings in urban areas was estimated and then the existence of a long-run relationship among variables of this function was studied using the bounds testing of the autoregressive distributed lag co-integration procedure. the t...

Petroleum (crude oil) is one of the most important resources of energy and its demand and consumption is growing while it is a non-renewable energy resource. Hence forecasting of its demand is necessary to plan appropriate strategies for managing future requirements. In this paper, three types of time series methods including univariate Seasonal ARIMA, Winters forecasting and Transfer Function-...

The aim of this paper is to classify order-preserving functions according to their arity gap. Noteworthy examples of order-preserving functions are the so-called aggregation functions.We first explicitly classify the Lovász extensions of pseudo-Boolean functions according to their arity gap. Then we consider the class of order-preserving functions between partially ordered sets, and establish a...

W characterize the equilibrium behavior in a broad class of competition models in which the competing firms’ market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm’s revenues and costs are proportional with its expected sales volume, with a cost rate that depends on the firm’s ch...

this study aims to estimate economic capacity and, in turn the utilization rate of economic capacity in iran’s electricity generation industry during 1350-1388. aggregate time series data for thermal power plants are used. with parametric restrictions for linear homogeneity in input prices imposed, capital demand function is first derived and estimated. this allows the derivation of economic ca...

This research investigates the role non-macroeconomic factors have played in subduing inflationary pressures in Japan. We investigate the hypothesis that the under-recognized presence of goods with high foreign produced content (FPC) in the consumer market basket has coincided with reduced price-level increases over the time period 1991-2004. An empirical examination and descriptive comparison ...

this paper empirically investigates the relationship between cpi inflation uncertainty, and private investment in the iranian economy from 1988 to 2010 by using quarterly data. we employ a bivariate var(5)-garch(1,1)-in-mean with diagonal bekk model to discover in a unified framework how are the interactions between the variables. in the model, conditional variance of inflation and private inve...
