基于生态学原理的城市用地规划研究——以龙泉山生态旅游综合功能区生态环境建设规划为例

在快速城镇化背景下,城市生态环境面临着城乡建设的巨大威胁。在资源与环境的双重约束下,传统规划思路面临着转变的需要。本文以龙泉山生态旅游综合功能区生态环境建设规划为例,运用生态学方法,关注自然环境特征,提出了以生态功能区划为基础的城市用地规划,并提出相应的规划策略及保障措施。从而可以达到保护生态环境,约束城乡建设行为与环境承载力相适应的目的。     

Changes in the second-moment properties of disaggregated capital flows

Using formal statistical tests, we detect (i) significant volatility increases for various types of capital flows for a period of changes in business cycle comovement among the G7 countries, and (ii) mixed evidence of changes in covariances and correlations with a set of macroeconomic variables.     

Trade in Parts and Components and the Industrial Geography of Central and Eastern European Countries

Growing inflows of FDI and the increasing integration of domestic firms into International Production Networks (IPNs) set up by EU-15 partners have yielded a rise in trade in parts and components for Central and Eastern European Countries (CEECs). As a consequence, new patterns of localization of industrial activities have been observed in the region since the mid-1990s. In this paper, I propose a comprehensive model of trade and production which tries to explain cross-country variations of sectoral output by comparative advantages (Ricardo, Heckscher–Ohlin) and agglomeration forces (home market effect, market potential), with a focus on the role played by trade in middle products. The empirical implementation reveals that the higher is the involvement in IPNs the larger is the domestic share of regional output. Comparative advantages are a crucial determinant of localization as opposed to agglomeration forces. I argue that these results can be interpreted as an assessment of the predictive power of two alternative trade theories. JEL no.  F10, F12, F14, F15     

Welfare Effects of Different Public Expenditures and Taxes in the Netherlands

This paper explores the welfare effects of public consumption, income transfers and public investment financed through different types of taxes. One surprising result is that, contrary to public consumption goods, public capital goods do not necessarily become less attractive if distortionary taxes, rather than lump-sum taxes, are necessary to finance them. The numerical simulations reveal that the net welfare effects of public investments in the Netherlands are typically positive if financed through lump-sum taxes or distortionary taxes on labor. However, if a source-based capital tax is adopted to finance public investments, the overall welfare effect may be negative.     

Taylor Rules for the ECB using Expectations Data*

We estimate Taylor rules for the euro area using Consensus Economics data for expected inflation and output growth, and compare these estimates with more conventional specifications in which actual outcomes are used. We find that the ECB takes expected inflation and expected output growth into account in setting interest rates, while in the more conventional model specification, the coefficient of realized inflation is not significantly different from zero.     

Polish and Belgian consumers' perception of environmentally friendly behaviour

The aim of this study was to design a method for evaluating the importance that consumers place on the characteristics of environmentally friendly (EF) products and on consumer EF behaviour. Attitudes and opinions of consumers regarding the EF value of the different aspects of consumer behaviour – purchasing, using and disposing of goods – were measured. The perception of EF behaviour was analysed for Belgian and Polish consumers, a Western and an Eastern European country. The cultural, economic and political differences between Belgium and Poland may imply that their consideration of EF behaviour is different. The perception of consumers about buying, using and disposing of EF products does not necessarily indicate their own EF behaviour, but it gives an indication of what consumers think is EF behaviour. On the basis of the results, policy‐makers and industry can diagnose the consumers' perceived cost–benefit relationship of EF consumer behaviour. An evaluation of what consumers think is EF can be made for the two countries. Marketers, government and EF organizations can draw on our research results when developing EF products and/or advertising campaigns.     

Financial Structure: Theories and Stylized Facts for Six Eu Countries

The article provides a survey of one of the most important elements of financial structure, namely credit to firms and households, by means of five distinguished theoretical issues. It is complemented by a survey of relevant stylized facts for six European countries. A cross-country comparison across Europe shows that indirect credit markets with banks as the main players are far more important than direct credit markets, and that the most striking difference in financial structure among the countries considered relates to debt maturity.     

Inherited agglomeration effects in hedge fund spawns

This paper studies inherited agglomeration effects, which we define as human capital that managers acquire while working in an industry hub that may be transferred to a spinoff. We test for inherited agglomeration effects in the hedge fund industry and find that hedge fund managers who previously worked in New York and London outperform their peers by about one percent per year. The results are driven by managers who worked in investment management positions previously, and are at least as large as traditional agglomeration effects that arise from being located in an industry hub contemporaneously. The evidence suggests that inherited agglomeration effects are an important, but as yet overlooked, factor influencing the performance of new firms. Copyright © 2013 John Wiley & Sons, Ltd.     

REVERSE DISCRIMINATION AND EFFICIENCY IN EDUCATION*

This article shows that reverse discrimination policies can find a justification purely on efficiency grounds. We study the optimal provision of education when households belong to different groups, differing in the distribution of the potential to benefit from education among individuals, which is private information. The main result is that high‐potential individuals from groups with relatively few high‐potential individuals should receive more education than otherwise identical individuals from groups with a more favorable distribution of these benefits.     

Keynes, Lucas and involuntary unemployment: a reply to Hayes

In this response to Mark Hayes's criticism of his article, ‘Lucason involuntary unemployment’, the author insists on theneed to draw a distinction between labour rationing (a marketoutcome) and unemployment (the activity of job seeking). Economictheory is mainly concerned with the former. Yet the issue ofthe voluntarity versus the involuntarity of unemployment pertainsto unemployment as an activity. Failing to make this distinctioncannot but lead to semantic confusion.
