the production of public goods like amenity value of the landscape, food security, preservation of rural communities and rural lifestyle, by agricultural sector is a subject that has been widely accepted by experts. however, in many policies and political analyses carried out, solely the production of private goods by the agricultural sector is paid attention and the important function of publi...

thermodynamic restrictions and simultaneous effects of operational conditions on the homogeneous rhodium-catalyzed carbonylation of methanol are studied in this line of research. it is shown that the general nrtl-virial model can be appropriated to study thermodynamics of the carbonylation. it is obtained that the reaction is kinetically and thermodynamically reasonable at temperatures above 42...

The objective of this work is to analyze the effects of decrease in water subsidies (increase in the price of the water) on various economic sectors in order to promote the conservation of this resource based on the actual price of water. But over the past decades, various subsidizing methods hold the cost of water down. On the other hand, the indiscriminate use of these resources led the gover...

Despite positive aspects of energy consumption, their negative externalities i.e., environmental pollutions, are considerable. Green taxes, paid for products and services that are not environmentally friendly, are recommended as an efficient way of improving health indices. Since, Iran is among the countries with high per capita consumption of energy, pollution can be a kind of threat. In this ...

We present a three dimensional hot Jupiter model, extending from 200 bar to 1 mbar, using the Intermediate General Circulation Model from the University of Reading. Our horizontal spectral resolution is T31 (equivalent to a grid of 48×96), with 33 logarithmically spaced vertical levels. A simplified (Newtonian) scheme is employed for the radiative forcing. We adopt a physical set up nearly iden...

I study a non-stochastic, perfect foresight, general equilibrium model with a banking system that may hold large excess reserves when the central bank pays interest on reserves. The banking system also faces a capital constraint that may or may not be binding. When the rate of interest on reserves equals the market rate, if the quantity of reserves is large and bank capital is not scarce, the p...

Many countries around the world are simultaneously experiencing an aging labor force, sharp reductions in the labor force participation rates of older workers, and high unemployment among younger workers. In response, some governments have encouraged early retirement by the elderly to free up jobs for the young, while others have adopted policies that promote old-age labor force participation. ...

This paper proposes a procedure to incorporate the conjectural variation approach in Computable General Equilibrium (CGE) analysis such that the strategic interaction among rival firms in international markets can be modelled. It shows how to calibrate the conjectured reactions of rival domestic and foreign firms. It also shows that the approach suggested by Harrison, Rutherford and Tarr (hence...

E C O N O M I C R E V I E W Second Quarter 2005 The 2001 recession displayed unique characteristics in comparison to other recessions. Although moderate in terms of the decline in output, the recession was unique in that the contraction in measured output was driven almost entirely by retrenchment in business capital spending. Consumer spending growth remained positive, and residential investme...
