We explore an input–output based framework for optimizing production in the Greek economy, under constraints relating to energy use, final demand, greenhouse gas emissions and solid waste. Using empirical data, we consider the effects on the maximum attainable gross value of production when imposing various pollution abatement targets. Our results quantify those effects as well as the magnitude of economic sacrifices required to achieve environmental goals, in a series of policy scenarios of practical importance. Because air pollution and solid waste are not produced independently of one another, we identify the settings in which it is meaningful to institute a separate policy for mitigating each pollutant, versus those in which only one pollutant needs to be actively addressed. The scenarios considered here represent a range of options that could be available to policy makers, depending on the country's international commitments and the effects on economic and environmental variables. 相似文献

Myopia and Addictive Behaviour 总被引:4,自引:0,他引:4
We present a theory of addictive behaviour which can account for addicts' apparent disregard for the future consequences of their current actions. The discounting of future utility is increasing in past consumption, indicating increasingly myopic behaviour as consumption increases. The intertemporal complementarity generated by the endogenous discounting produces multiple steady states which can account for the simultaneous existence of myopic addicts and non-myopic non-addicts within a time consiste nt expected utility framework. The theory also accounts for the probabilistic incidence of addiction and successful rehabilitation and the possibility of recurrence. 相似文献

The absence of monetary policy within a currency union increases the need for structural reforms that make the participating economies more flexible. However, the absence of exchange rate risk with respect to the other members of the union may reduce the urgency for such reforms. A number of other considerations also suggest that theory is ambiguous about the impact of participating in a currency union on progress in structural reforms. This paper addresses this issue empirically for the euro area. The results suggest that reforms in the euro area seem to have decelerated following the introduction of the euro, but from a fast pace. The paper discusses a number of possible explanations, including “reform fatigue,” the absence of “market punishment,” and “good-times” complacency. Estimates from an empirical growth model suggest that the slowing of reforms may slow down annual output growth by up to 0.2%. However, the results are preliminary and depend on the area of reform considered. Furthermore, the reform dynamics may change with the euro area starting slowing at the end of 2007. 相似文献

This paper proposes an alternative way of testing FOREX efficiency for developing countries. The FOREX market will be efficient if fully reflects all available information. If this holds, the actual exchange rate will not deviate significantly from its equilibrium rate. Moreover, the spot rate should deviate from its equilibrium rate by only transitory components (i.e. it should follow a white noise process). This test is applied to three Central and Eastern European Countries — members of the EU. Considering an LSTAR model we find no evidence of nonlinear adjustment in the misalignment series. So, linear unit root tests imply that the Poland/Euro FOREX market is efficient, the Czech/Euro FOREX market is not, while the Slovak/Euro FOREX market is quasi-efficient. 相似文献

The paper presents a variety of neural network models applied to Canadian–US exchange rate data. Networks such as backpropagation, modular, radial basis functions, linear vector quantization, fuzzy ARTMAP, and genetic reinforcement learning are examined. The purpose is to compare the performance of these networks for predicting direction (sign change) shifts in daily returns. For this classification problem, the neural nets proved superior to the naïve model, and most of the neural nets were slightly superior to the logistic model. Using multiple previous days' returns as inputs to train and test the backpropagation and logistic models resulted in no increased classification accuracy. The models were not able to detect a systematic affect of previous days' returns up to fifteen days prior to the prediction day that would increase model performance.

Previous literature has established a positive correlation between openness to international trade and GDP per capita growth for developed and developing economies in recent decades. However, looking at historical evidence from 1870 to the present, this paper finds no support for a positive growth-openness connection before 1970. In fact, the correlation is negative for the period 1920–1940. Cross-country growth regressions estimated for the period 1920–1990 suggest that the positive correlation between openness and growth is only a recent phenomenon. The paper provides useful conclusions regarding the robustness not only of the openness variables but also of other growth determinants. 相似文献

This paper explores in a yearly panel of nineteen OECD countries from 1970–2002 the effects of fiscal policy changes on private consumption in recessions and expansions. In the presence of binding liquidity constraints on households, fiscal policy is more effective in boosting private consumption in recessions than in expansions. The effect is more pronounced in countries characterized by a less developed consumer credit market. This happens because the fraction of individuals that face binding liquidity constraints in a recession will consume the extra income generated following an unanticipated tax cut or government spending increase. 相似文献

This article develops a theoretical model that explores firms' abatement choices. The main results are: First, in a market comprised of a not sufficiently large number of heterogeneous firms always there exists a subset of firms that are willing to undertake abatement activities, if their marginal altruistic cost of emissions is positive. Second, a low emission tax induces abatement when a firm is egoistic or if its altruistic cost of emissions has a concave structure. In contrast, if the firms’ altruistic cost of emissions has a convex structure, then intermediate emission taxes are required. Third, the effect of firms’ altruistic cost of emissions on the emission tax that induce the socially optimum abatement is also conditional on the genuine altruistic preferences and finally, the social planner has an incentive to impose a Pigouvian emission tax when firms are profit maximizers. Otherwise, a lower tax suffices. 相似文献
