ABSTRACT- Iran achieved its self-sufficiency goal in wheat production a few years ago, perhaps at the expense of decreasing the production of other grains specially barley as stated by critics in the country. Considering the dependency of wheat and barley markets on each other, policy preference functions were estimated separately for each market. Incorporating political weights, a game theory ...

The use of natural resource revenues for achievement of development has been a challenging issue for resource abundant countries. These challenges stem from the fact that incomes from natural resources are non-durable, unpredictable and uncertain. Different countries have pursued various approaches and tools for managing these revenues to avoid economic fluctuations. The international organizat...

Cities regularly face a wide range of economic development choices that inevitably create both winners and losers within their communities. Proper assessment of the impacts of such choices requires not only an appropriate modelling framework but also explicit understanding and incorporation of a city’s income distribution priorities. This paper proposes that a computable general equilibrium (CG...

BACKGROUND Economic impact assessment of invasive species requires integration of information on pest entry, establishment and spread, valuation of assets at risk and market consequences at large spatial scales. Here we develop such a framework and demonstrate its application to the pinewood nematode, Bursaphelenchus xylophilus, which threatens the European forestry industry. The effect of spat...

Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts. We investigate the importance of heterogeneity using random-assignment data from Connecticut’s Jobs First waiver, which features key elements of post-1996 welfare programs. Estimated quantile treatment effects...

Air quality co-benefits can potentially reduce the costs of greenhouse gas mitigation. However, whereas many studies of the cost of greenhouse gas mitigation model the macroeconomic welfare impacts of mitigation, most studies of air quality co-benefits do not. We employ a U.S. computable general equilibrium economic model previously linked to an air quality modeling system and enhance it to rep...

abstract: on december 2010, the government of iran ended the decades-long subsidy program for bread and energy products and launched the targeted subsidy reform program that considerably raised prices of food products. the objective of the study was to measure welfare impacts of food price changes on iranian urban households between two survey data of 2009/10 and 2011/12 which were taken from i...

Household welfare is inseparable from the environment because of its dependence on ecosystems and their services. However, linking household welfare and ecosystems in order to inform differentiated household livelihood development in spatially heterogeneous regions is still a great challenge. Based on a field survey of 1754 households, we grouped the relationships between household welfare (def...

This paper uses stated and revealed preference data to quantify differential welfare impacts from changes in congestion at outdoor recreation sites that support multiple activities. The results indicate that welfare impacts from congestion vary by congestion point, site, and activity within a given site. Estimating willingness to pay (WTP) for multiple sites and activities allows for parametric...
