耕地整理潜力评价指标体系研究

研究目的:构建耕地整理潜力评价指标体系可以定量反映和衡量通过耕地整理挖掘耕地利用的潜力,为土地整理专项规划、耕地整理项目设计提供科学依据.研究方法:理论分析法、专家咨询法.研究结果:从耕地整理的自然潜力和现实潜力两方面建立了评价指标体系,在界定指标内涵的基础上采用适宜的方法实现了指标的定量化.研究结论:耕地整理潜力可分为耕地整理的自然潜力和现实潜力.耕地整理自然潜力在评价时,主要从耕地整理扩展可利用空间、提高生产能力、降低生产成本、改善生态环境与调整产权关系5方面选取评价指标.耕地整理现实潜力在评价时,主要从待整理土地所处的社会经济区位、待整理土地本身的基础设施状况和区域耕地后备资源状况等方面选取评价指标.     

沙漠化耕地调查评价与生态恢复

自然条件和不合理的土地利用方式的耦合造成并加速了耕地沙漠化,沙漠化已经造成严重的土地资源退化和生态环境问题,尤其是耕地沙漠化对工农业生产造成严重影响。沙漠化耕地调查评价与生态恢复已成为土地资源合理利用的当务之急。     

Natural Resource Booms and Inequality: Theory and Evidence*

We develop a theory, in the context of a two‐sector growth model in which learning‐by‐doing drives growth, to explain the time path of income inequality following natural resource booms in resource‐rich countries. Under the condition of a relatively unskilled labor intensive non‐traded sector, inequality falls immediately after a boom, and then increases steadily over time until the initial impact of the boom disappears. Using data for 90 countries between 1965 and 1999, we find evidence in support of the theory, especially for oil and mineral booms. We also find that uncertainty about future commodity prices increases long‐run inequality.

Oil prices and life satisfaction: asymmetries between oil exporting and oil importing countries

In spite of general consensus on the importance of oil prices for objective measures of economic well-being across countries, almost no research has been carried out to analyse the effects of oil prices on subjective well-being internationally. Using the World Values Survey (2009 World Values Survey 1981–2008 Official Aggregate v.20090901. (2009) World Values Survey Association, Aggregate File Producer: ASEP/JDS, Madrid. Available at www.worldvaluessurvey.org (accessed September 2010). [Google Scholar]), we help fill this gap by studying the effects of oil prices on life satisfaction for two groups of countries, oil importers and oil exporters. Although some previous studies have shown negative effects of oil prices on subjective well-being of one oil importing country the United States, since it is an outlier in terms of dependence on automobiles and in gasoline consumption per capita, these findings may not be representative of other oil importing countries. Our results show that, in fact, oil prices have quite strong negative effects on life satisfaction in a sample of over 40 oil importing countries. By contrast, for oil exporting countries for which there have been virtually no previous quantitative studies, but theoretical analyses suggest the results could be ambiguous, we find strong positive effects on life satisfaction. Hence, our results reveal quite strong asymmetries in the effects of oil prices on life satisfaction between oil importers and oil exporters.     

Characterisitcs of Exporting and Nonexporting Joint Ventures in Saudi Arabia

The study profiled 83 exporting and onexporting manufacturing joint ventures (JVs) in Saudi Arabia. This represents about one-fourth of all manufacturing JVs in operation at the end of 1987. Stepwise discriminant analysis showed that a set of 9 characteristics representing 4 factors were signficant in differentiating the two groups. Exporting JVs tend to be larger, produce industrial goods in more technology intensive industrial sectors, and be more leveraged than nonexporting JVs. Potential limitations of these findings, and their implications for the policy makers are also discussed.

The Role and Current Status of IFRS in the Completion of National Accounting Rules – Evidence from the Netherlands

Abstract

Dutch law (B2T9) is positive towards IFRS. IFRS may be used by all entities, there is a specific option for entities using IFRS in the consolidated financial statements to apply an IFRS-friendly version of B2T9 in its separate financial statements, and IFRS for SMEs can be used by non-listed and non-regulated companies in combination with B2T9. In the process of adoption of the 2013 EU Accounting Directive only limited references have been made to IFRS. This is not an indication of a reduced interest in IFRS, but is a result of limiting the changes of B2T9 to those that are necessary as a result of changes at the EU level. The Dutch Accounting Standards Board, issuing Dutch Accounting Standards (DAS), considers IFRS when developing and changing its standards. In addition to the IFRS option DAS often include one or more additional optional treatments that are considered suitable for non-listed companies. The Dutch regulatory authority AFM is also positive towards IFRS and even advocates elimination of non-IFRS options from Dutch GAAP as much as possible. The number of major differences between Dutch GAAP and IFRS is relatively limited, with only a few differences that cannot be avoided by an entity when preparing financial statements under Dutch GAAP.     

Shocks to Terms of Trade and Risk-premium in an Intertemporal Model: The Dutch Disease and a Dutch Party

In this paper, we analyze the impact of terms of trade and risk-premium shocks on a small open economy in an intertemporal Dutch disease model, with international capital mobility. Given that an improvement in the terms of trade is associated with a decrease in the risk-premium on lending to this economy, we find that this can lead to a Dutch party (rather than Dutch disease) in which real exchange rate appreciation is associated with an expansion of the capital-intensive traded sector, hence, pro-industrialization. The economy also accumulates more debt in the long-run in response to the lower borrowing costs.
