This paper is based on research carried out in an EU Framework project, concerning the better integration of mobility management (MM) with land use planning. The objective of the paper is to analyse how, and how far, policies in this field of action can transfer from one member state to another, and to compare this to the theory of policy transfer put forward by Dolowitz and Marsh (2000), using their theory as an analytical framework, but also informing that theory. After providing a definition of this form of integration, the paper explains how far MM and land use planning are currently integrated in the EU member and other states covered in the research (Sweden, Germany, Spain, Lithuania, Poland, Slovenia, Switzerland, the UK, as well as Ireland and the Netherlands). It then presents the results of planning simulation workshops in five of these countries, where a group of planning professionals from each state considered real development sites and how MM could be integrated with the development. It shows that there is scope for transfer but concludes that barriers such as language, differing planning traditions, and the problem of transferring a new policy idea within a country will limit the scope of policy transfer significantly. Nonetheless, it sees a role for EU projects of this nature in encouraging initial consideration of new policy ideas. 相似文献

This article proposes the Immigrant Business Enterprises Classification Framework to organize immigrant‐owned businesses into categories associated with different levels of business integration into a host country's mainstream business community. The article applies the framework and reports the findings of structured face‐to‐face interviews with 199 Hispanic business enterprises (HBEs) in Indianapolis. The authors find Hispanic‐owned businesses hold different characteristics depending upon the integration category in which they are classified; the findings suggest that to support immigrant entrepreneurship, governments, business development organizations, and researchers should address category‐specific challenges, opportunities, and needs. © 2010 Wiley Periodicals, Inc. 相似文献

In the Generalized Bin Packing Problem (GBPP), given two sets of compulsory and non-compulsory items characterized by volume and profit and a set of bins with given volume and cost, we want to select the subset of profitable non-compulsory items to be loaded together with the compulsory ones into the appropriate bins in order to minimize the total net cost. Lower and upper bounds to the GBPP are given. The results of extensive computational experiments show that the proposed procedures are efficient and the bounds are tight. 相似文献

This paper critically analyses the approach to the determination of values, or commodity contents, developed by Fujimoto and Opocher in 2009. Even setting aside various problematic definitional issues, the broader implications of the approach for classical theory are unclear. First, the value‐theoretic definitions of skill differentials and bads capture at best necessary conditions and it is unlikely that such definitions can be provided by focusing only on the technological data of the economy. Second, the approach has various interesting implications concerning the relation between productiveness and exploitation that directly contradict some of the authors' claims. 相似文献

This study reconsiders the role of jumps for volatility forecasting by showing that jumps have a positive and mostly significant impact on future volatility. This result becomes apparent once volatility is separated into its continuous and discontinuous components using estimators which are not only consistent, but also scarcely plagued by small sample bias. With the aim of achieving this, we introduce the concept of threshold bipower variation, which is based on the joint use of bipower variation and threshold estimation. We show that its generalization (threshold multipower variation) admits a feasible central limit theorem in the presence of jumps and provides less biased estimates, with respect to the standard multipower variation, of the continuous quadratic variation in finite samples. We further provide a new test for jump detection which has substantially more power than tests based on multipower variation. Empirical analysis (on the S&P500 index, individual stocks and US bond yields) shows that the proposed techniques improve significantly the accuracy of volatility forecasts especially in periods following the occurrence of a jump. 相似文献

A new round of trade negotiations through the World Trade Organization (WTO) was launched in 2001. One of the major aims of the Doha Development Round is to reduce agricultural protection and impose greater discipline on domestic agricultural subsidies, particularly those that are the most trade distorting. In this article, we examine whether the proposed WTO modalities for agriculture will actually achieve this aim in Norway, which ranks among the top providers of government assistance for agriculture. Norway has a complex system of farm subsidies buttressed by substantial import protection. The extent to which its agricultural support policies will have to change in response to new WTO disciplines provides an important indication of how successful these are likely to be. We find that Norway will probably be able to sustain its current agricultural activity and production levels while staying within the new WTO rules. Following recent practice in some other WTO members, Norway will be able to reduce its notified support without making real changes in some of its programmes. However, there will have to be a shift from market price support, which is paid for by consumers through higher food prices, to budgetary support paid by taxpayers. This could generate increased domestic pressure for policy reform. 相似文献

By focusing on sovereign defaults, this paper introduces a multidimensional distance‐to‐collapse point based on a two‐step procedure. The first step is nonparametric and provides an early warning system that signals a potential crisis whenever preselected leading indicators exceed specific thresholds. The second is parametric and incorporates the first‐step country default predictors within a probit specification. Such a two‐step procedure generalizes the distance‐to‐default à la Merton within a multidimensional setting, wherein we care about the distance of each indicator from its threshold. Empirical evidence about debt crises of emerging markets over the period 1975–2002 proves that our methodology predicts 80% of the total defaults and non‐defaults in and out of sample.

The serial correlation of high‐frequency intraday returns on the Italian stock index futures (FIB30) in the period 2000–2002 is studied. It is found that intraday autocorrelation is mostly negative for time scales lower than 20 minutes, mainly due to the bid–ask bounce effect. Although this supports the efficiency of the Italian futures market, evidence that intraday serial correlation becomes positive in high‐volatility regimes is also provided. Moreover, it is found that it is mainly unexpected volatility that makes serial correlation rise, and not its predictable part. The results are supportive of the K. Chan (1993) model. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:61–84, 2006 相似文献

Several new parameters characterizing the shape of statistical distributions are discussed. These parameters have earlier been considered for characterization of the shape of territories. By means of these parameters we describe general spread and spread along the axes, as well as asymmetry, of univariate theoretical and empirical distributions. General formulas for the parameters are given, and the particular formulas for the most of the common theoretical distributions are also listed. Some numerical values are tabulated, to illustrate their usefulness. Affine transformations are considered, and many applications and extensions are hinted upon. 相似文献
