Housing costs in the UK have exploded in recent decades. Contrary to what is often claimed, this has nothing to do with population density, demographics or a lack of public housing. A review of the empirical literature shows that the key determinant of housing costs is the severity of planning restrictions. Faced with a well‐organised NIMBY opposition, the coalition failed in its attempt to make the planning system more development‐friendly. This is not surprising, because the current system provides incentives which make NIMBYism a rational option. The coalition ought to address these incentives rather than trying to sidestep them.  相似文献

In the Comprehensive Spending Review and in the Budget 2010, the Liberal–Conservative coalition has announced cost‐cutting measures in the benefit system. Some of these measures can be interpreted as ‘random cuts’, where the given scope and structure of a spending programme is retained, while bits and pieces are chopped off here and there. Others can be interpreted as more strategic measures, or reconsiderations of the proper role of government in the respective area. However, where the coalition has pursued a more strategic approach, it has not followed it through consistently. The coalition's consolidation strategy relies too much on temporary caps and freezes, which will eventually expire and give way to renewed spending pressures.  相似文献

European agricultural systems are going through a modernisation process involving radical structural changes. To tackle these important challenges, technology foresight has been employed as a systematic, participatory, intelligence gathering exercise focusing on future R&D investments in sustainable agricultural systems and green technologies. Because reliable data on emerging technology are scarce, any assessment has to be based to a large extent on qualitative methods and on an operational conception of sustainability using priority indicators. The paper describes the Danish Green Technological Foresight on Environmental Friendly Agriculture (GTFEFA). It treats this as a case study and examines the way in which a group of interested parties arrived at recommendations on the application of a number of emerging agriculture-related technologies. Two questions are then addressed: Can technological foresight simultaneously: (1) systematically describe and evaluate the consequences of employing emerging technologies in order to choose between alternatives, and (2) prioritise investments in emerging technologies so as to favour innovation. The discussion here is intended to help meet the challenge of operationalising the term ‘sustainability’, so that environmental friendly agricultural technology can be assessed against priority indicators. Finally, it is suggested that, provided that clear criteria for assessing the sustainability of emerging technologies are identified and made explicit, technology foresight offers a space for dialogue and exploration in contested territory.  相似文献

DIFFUSION MODELS FOR EXCHANGE RATES IN A TARGET ZONE   总被引:2,自引:0,他引:2  
We present two analytically tractable diffusion models for an exchange rate in a target zone. One model generalizes a model proposed by De Jong, Drost, and Werker (2001) to allow asymmetry between the currencies which is often an important feature of data. Estimation of the model parameters by the method of Kessler and Sørensen (1999) using eigenfunctions of the generator is investigated and shown to give well-behaved estimators that are easy to calculate. The method is well suited to the models because the eigenfunctions are known so that explicit estimating functions are obtained, and because the state space is a finite interval, for which it is known that the method can be made arbitrarily efficient by including sufficiently many eigenfunctions. The model fits data on exchange rates in the European Monetary System well. In particular, the asymmetry parameter is significantly different from zero for three out of four currencies. An alternative diffusion model is presented with similarly nice properties, but with different dynamics that allow constant volatility near the boundaries of the target zone. No-arbitrage pricing of derivative assets is considered, and the effect of realignments is briefly discussed.  相似文献

Geographic clusters have received first‐order policy attention despite our limited academic knowledge about them. I explain how coagglomeration patterns of industries can inform the analysis of clusters by allowing us to better delineate them; to explore the causal mechanisms underlying them; and to more finely assess their impact on various economic outcomes.  相似文献

There have been two major attempts to introduce market mechanisms into England's National Health Service: the ‘internal market’ reform project of the 1990s, and the ‘quasi‐market’ of the 2000s. Despite their similarities, the former attempt was on balance unsuccessful while the latter succeeded. This article examines and compares the outcomes of the two periods, analysing the reasons for their relative successes and failures. It goes on to highlight options for future reforms that would build on those achievements.  相似文献

The current paper extends previous results on Hodrick–Prescott (HP) filtering and shows that it is possible to implement the judgement-augmented, or restricted, HP filter within the state-space framework. The implementation entails augmenting the vector of measurements and altering one of the system matrices of the state-space model for the HP filter. Restrictions can thereby be incorporated in the HP filter, making, e.g., estimation more accessible. An application to US GDP gap estimation illustrates how the restricted filter could be usefully applied in an empirical macroeconomic setting.  相似文献

Using an extensive database of 356,463 sell‐side equity analysts' reports from 2002 to 2009, this study is one of the first to analyze the readability of analysts' reports. We first examine the determinants of variations in analyst report readability. Using several proxies for ability, we show that reports are more readable when issued by analysts with higher ability. Second, we test the relation between analysts' report readability and stock trading volume reactions. We find that trading volume reactions increase with the readability of analysts' text, consistent with theoretical models that predict that more precise information (and hence more informative signals) results in investors' initiating trades. These results support the view that the readability of analysts' reports is important to analysts and capital market participants.  相似文献
