iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...

We analyze a dynamic version of the Akerlof±Wilson ``lemons'' market in a competitive durable good setting. There is a ®xed set of sellers with private information about the quality of their wares. The price mechanism sorts sellers of different qualities into different time periodsÐprices and average quality of goods traded increase over time. Goods of all qualities are traded in ®nite time.

Other types of aggregation, such as the democratic index, are also possible, and,...

In a two-period model with uncertainty about life expectancy, we analyze several measures which are typically included in a social security reform: tax incentives for private life annuities, a cut in the social security benefits and an increase in the social security tax. First, we look at the demand side and study the effects on old-age provision for a given annuity price. It is shown that tax...
