Many countries have large or increasing migrant populations. We estimate the elasticity of private-sector employment to nonoil GDP for nationals and migrants using a Seemingly Unrelated Error Correction (SUREC) model. We use data from the Gulf Cooperation Council (GCC) countries, which have a particularly large share of foreign workers. Our results indicate that the employment response is statistically significantly lower for nationals, who have an estimated short-run elasticity of only 0.15 and a long-run response of 0.7, than for migrants, where the short- and long-run elasticities are 0.35 and almost unity. Lower elasticities could signal higher labour market adjustment costs. In the context of low oil prices, forecasts imply a significant jobs shortfall for nationals in the coming years. 相似文献

We investigate whether non‐reciprocal preferential regimes granted by the European Union have an impact on agricultural export flows from beneficiary countries while accounting for the costs of compliance that may prevent exporters from taking full advantage of potential benefits. Compliance costs are heterogeneous and difficult to measure. We proxy their influence and specify a model that allows for a different preferential margin impact according to the proxy costs. Adopting the gravity framework and using a sample of 554 lines of agricultural products for 131 developing countries in 2002, we find that the costs of compliance play a role in making the schemes work: the lower the costs, the greater the impact of the preferential margins. Moreover, the estimated margin effect differs between different regimes. 相似文献

It is argued that estimating the damage costs of a certain benchmark climate change is not sufficient. What is needed are cost functions and confidence intervals. Although these are contained in the integrated models and their technical manuals, this paper brings them into the open in order to stimulate discussion. After briefly reviewing the benchmark climate change damage costs, region-specific cost functions are presented which distinguish tangible from intangible losses and the losses due to a changing climate from those due to a changed climate. Furthermore, cost functions are assumed to be quadratic, as an approximation of the unknown but presumably convex functions. Results from the damage module of the integrated climate economy modelFUND are presented. Next, uncertainties are incorporated and expected damages are calculated. It is shown that because of convex loss functions and right-skewed uncertainties, the risk premium is substantial, calling for more action than analysis based on best-guess estimates. The final section explores some needs for further scientific research. 相似文献

How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other. 相似文献

The main purpose of the present study is to analyse the emission dynamics of atmospheric and water pollutants in Russia and cost of their removal in the 1980s and early 1990s, and to forecast them by means of a Dynamic Input–Output Model according to different scenarios of future economic development till 1998. Main results of the work are:– methodological principles have been elaborated for singling out the environmental protection sector within the national economy;– a method has been offered for including the ecological block into a Dynamic Input–Output Model of the Russian economy;– a method of data preparation has been elaborated for the ecological block of the above-named model, the data base which characterizes the ecological situation in Russia has been formed and analysed;– calculations for 1994–1998 have been executed for forecasting the economic and ecological development of Russia using the above-mentioned model and the results obtained have been analysed. The results showed that if the existing tendencies towards low environmental protection capital costs remain the same, then the negative environmental impact will increase. In order to implement ecological programs and international agreements, to increase the proportion of removed pollutants, it is necessary to increase substantially expenditures on purifying water and air resources. The proportion of environmental protection investments in the total amount of the national economy capital costs should increase by up to 12–40% according to different scenarios of the economic development and different purposes of the environmental protection policy. 相似文献

Summary. A model that includes the cost of producing money is presented and the nature of the inefficient equilibria in the model
are examined. It is suggested that if one acknowledges that transactions are a form of production, which requires the consumption
of resources, then the concept of Pareto optimality is inappropriate for assessing efficiency. Instead it becomes necessary
to provide an appropriate comparative analysis of alternative transactions mechanisms in the appropriate context.

This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography. 相似文献
