Results from the 1983 census of Israel are presented concerning households, marriage, married couples, and fertility. Data on households are based on the complete enumeration; the remaining data concern a 20 percent sample of households. Information is included on households by number of persons in household; sex, religion, and age of head of household; type of household; age at first marriage; age differences between husband and wife; and family size. Selected data are reported for Jews by continent of origin, and for non-Jews by religion.  相似文献

近 2 0年来 ,森林资源下放给当地社区管理已成为世界的趋势。我国从 1980年开始林业“三定”以来 ,为发展林业 ,鼓励造林 ,出台了许多林业政策 ,也产生了多种形式的森林资源分权管理模式。如何系统地探索森林资源分权管理的效果及其影响因素 ,以期为当地的森林资源管理提供有效的信息 ,成为人们关注的热点。本文首先就系统地探索森林资源分权管理及其效应的体系进行了论述 ,然后以大土村作为案例 ,就有关内容进行了探讨  相似文献

This paper uses duality theory to develop a model of European Community agriculture. The model is used to investigate the impact of the land set-aside provision of the recent package of reforms of the Common Agricultural Policy. We assume that producers chose output and variable input levels that maximize difference between revenue and variable cost. By including first-order conditions for the allocation of land across its uses, we impose that the observed allocations are profit-maximizing allocations. To overcome the problem of incorporating many outputs into an estimable production structure, we imposed a priori the restriction that the technology was weakly separable in major categories of outputs. With this restriction, it was possible to model production decisions in stages using consistent aggregates in the latter stages.  相似文献

We evaluate the impact on trade of regional trade agreements (RTAs) using a panel data approach at the detailed product level which exploits exports to third destinations and imports from third origins as benchmarks. This method is robust to both endogeneity and heterogeneity across agreements and across products, and allows differentiation between the impacts of tariff provisions and non-tariff provisions. The analysis covers agricultural and food products for 74 country pairs linked by an agreement entered into force during the period 1998–2009. Our estimate of the mean elasticity of substitution across imports at product level is slightly below four. Counterfactual simulations suggest that RTAs have increased partners’ bilateral agricultural and food exports by 30–40 % on average, with marked heterogeneity across agreements. Also, RTAs are found to increase the probability of exporting a given product to a partner country although this impact is small. Finally, we found non-tariff provisions have no measurable trade impact.  相似文献

Both the European Union and the United States grant non‐reciprocal preferences to developing countries under the Generalised System of Preferences as well as under several regional schemes. The benefits of these preferences have recently been questioned. Several authors have pointed out the under‐utilisation of these preferences due to the constraints attached. There have been claims that rules of origin requirements and administrative costs, as well as uncertainty on eventual eligibility, have deterred exporters from using preferential regimes. We calculate various indicators of the utilisation of preferences in the agricultural, food and fisheries sector. We conclude that only a very small proportion of the imports eligible for these preferences is actually exported outside a preferential regime. The rate of utilisation is therefore high. However, the flow of imports from the poorest countries remains very limited in spite of rather generous tariff preferences, which leads to questions over the overall impact of the preferential agreements. In addition, preferential regimes overlap, and in such cases some regimes are systematically preferred to others. We use econometric estimates of the (latent) cost of using a given preference to explain why particular regimes are used. We focus on possible explanations, such as the cumulation rules (that restrict the use of materials originating from other countries), fixed administrative costs and differences in the preferential margin.  相似文献
