This study identifies and analyzes factors that affect a learner's knowledge, comprehension, and application of economics by racial and gender grouping. A decomposition model is used to evaluate the impact of attitudinal effects and other exogenous variables on economic cognition. Preliminary findings suggest that the attitude of black students towards economics instruction differs from their white cohorts while no gender differences are found.  相似文献

This paper develops the key finding of Ozanne, Hogan and Colman (2001) that risk aversion among farmers ameliorates the moral hazard problem in relation to agrienvironmental policy compliance. It is shown that risk averse farmers who face uncertainty in their production income are more likely to comply with such a policy as a means of risk management. In addition, it is shown that a principal who has control over both the level of monitoring and the size of penalty, if detected, can reduce non‐compliance by adjustments to these instruments which increase the variance of farmers' income but leave the expected penalty unchanged. It is concluded that risk management by both principals and agents has the potential to diminish the moral hazard problem, especially given proposed developments in agri‐environmental policy in the European Union.  相似文献

This article investigates the impact of a protein premiums and discounts system on the income stream from growing wheat. Based on a biological relationship between protein and yield in uncertain seasonal conditions, it shows that such a system reduces the expected level and variability of wheat income. It is subsequently argued, using a numerical analysis, that protein payments affect both the attraction to wheat growers of forward contracts and the value of land used for wheat. The nature of both of these impacts is related to the level of seasonal variability affecting the land. Consequently, wheat growers in the more unreliable regions of the wheatbelt may have been particularly disadvantaged by the system.  相似文献

Conclusions It has been argued that while in the traditional analysis of the classic CPE the exchange rate has only an accounting function, inappropriate methods of national income accounting can lead to changes in the exchange rate generating changes in the real economy, provided that trade in unbalanced in foreign currency prices. This thesis was explored by examining the way the profits from foreign trade were calculated by the Ministry of Foreign Trade, and then transferred to the state budget. It was shown that the correct measure of the state's increased command over domestic resources from engaging in foreign trade, derived from the implicit taxes on that sector, was the ministry's profits on its domestic operations, the first term in (2). However, evidence was presented which suggested that its profits on foreign currency account measured in domestic currency, the second term in (2), were also passed over to the state budget. This implies that transferred profits from foreign trade will overstate the underlying command over resources when there is a balance of payments surplus, and understate them when there is a deficit. The consequence of this is that the domestic economy faces a series of erratic, though small, inflationary and deflationary impulses, regardless of changes in the exchange rate.The theoretical role of the preisausleich system was explored in some detail and it was argued that, although the system has been designed to insulate the domestic economy from external disturbances, there were clear reasons why it had come to play a major part in revenue raising. Specifically, it is administratively convenient to tax resources at their point of entry into or exit from the economy; the taxation of foreign trade widens the tax base and reduces the visibility of the tax system. But, of course, this grafting onto the preisausgleich of a second major function of revenue raising does lead to the development of a further channel through which external disturbances can pass into the domestic economy. That is external disturbances impact on the domestic economy not only through the production and welfare effects of changing exports and imports, and through whatever tenuous links are allowed between foreign and domestic prices, but also insofar as those disturbances affect the ministry's profits from foreign trade. In short, foreign economic disturbances show up in variations in the position of the non-inflationary government budget constraint. To that extent the second function of the preisausgleich impairs its ability to perform its original insulation function. In a minor way, the successful non-inflationary performance of the insulation function has always required adjustments in the government budget constraint. But the growth in the importance of foreign trade taxation has magnified the importance of this phenomenon, and led to a trade-off between the two functions.University of Bath.

This paper deals with the specification of pollution abatement in dynamic computable general equilibrium (CGE) models and analyses the dynamic feedback mechanisms between economy and abatement in the context of environmental policy. A Ramsey-type economic model is presented, in which bottom-up technical and economic information on abatement techniques is integrated in a top-down dynamic CGE context. The practical suitability of the specification is illustrated by an empirical application for climate change and acidification in the Netherlands. The results show that a mixture of some slowdown of economic growth, a substantial restructuring of the economy and implementation of most technical abatement measures is optimal.  相似文献

In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.  相似文献

It is generally acknowledged that the growth rate of output, the seasonal pattern, and the business cycle are best estimated simultaneously. To achieve this, we develop an unobserved component time series model for seasonally unadjusted US GDP. Our model incorporates a Markov switching regime to produce periods of expansion and recession, both of which are characterized by different underlying growth rates. Although both growth rates are time-varying, they are assumed to be cointegrated. The analysis is Bayesian, which fully accounts for all sources of uncertainty. Comparison with results from a similar model for seasonally adjusted data indicates that the seasonal adjustment of the data significantly alters several aspects of the full model.
