We argue that the standard Constitutional Political Economy defence of constitutionalism, that derives from an argument relating to the shift from narrowly self-interested motivations in the in-period context to relatively general-interest decision making in the constitutional context, is flawed precisely because it is intended to relate to essentially political settings where decision making must be construed as collective in nature. We suggest an alternate account of expressive constitutionalism that points to a specific defence of constitutional conventions that are insulated from popular voting.  相似文献

This paper examines the formation of explicitly-reported price expectations in the UK. Expectations are formed over a long period, and a general distributed lag provides a superior explanation to that provided by a second-order error-learning form. The error-learning mechanism is shown to be biased when lagged expectations incorporate a random shock, and when expectations are reported more frequently than the length of the forecast horizon.  相似文献

Economic models of markets with imperfect information have increasingly involved high degrees of theoretical sophistication. So far there has been no movement beyond qualitative prediction. This paper attempts to make quantitative assessments of the new features arising from imperfect information following on recent work by Braverman (1980) and Braverman and Dixit (1981). The information structure of these models is based on non-sequential search, where consumers enter the market only once. It is of interest to question under what circumstances single price equilibria will exist under different assumptions about the distribution of search costs. Therefore for particular families of demand, cost and information conditions, the possibilities of competitive, monopolistic and two price equilibria are examined and their relative likelihoods assessed.  相似文献

Geography and retail store locations are inherently bound together; this study links food retail changes to systemic logistics changes in an emerging market. The later include raising income and education, access to a wide range of technologies, traffic and transport difficulties, lagging retail provision, changing family structure and roles, as well as changing food culture and taste. The study incorporates demand for premium products defined by Kapferer and Bastien [2009b. The Luxury Strategy. London: Kogan Page] as comprising a broad variety of higher quality and unique or distinctive products and brands including in grocery organic ranges, healthy options, allergy free selections, and international and gourmet/specialty products through an online grocery model (n?=?356) that integrates a novel view of home delivery in Istanbul. More importantly from a logistic perspective our model incorporates any products from any online vendors broadening the range beyond listed items found in any traditional online supermarkets. Data collected via phone survey and analysed via structural equation modelling suggest that the offer of online premium products significantly affects consumers’ delivery logistics expectations. We discuss logistics operations and business management implications, identifying the emerging geography of logistic models which respond to consumers’ unmet expectations using multiple sourcing and consolidation points.  相似文献

Following a decade since privatisation during which attempts at introducing competition for water services have been slow and somewhat ineffective, the government is now carrying out a review. Large-volume users have a thirst for water competition brought about by competition in other utilities. The economic regulator needs to allow a new contestable market for industrial water services to develop whilst major structural and legislative changes to facilitate competition are contemplated.  相似文献

Least squares model averaging by Mallows criterion   总被引:1,自引:0,他引:1  
This paper is in response to a recent paper by Hansen (2007) who proposed an optimal model average estimator with weights selected by minimizing a Mallows criterion. The main contribution of Hansen’s paper is a demonstration that the Mallows criterion is asymptotically equivalent to the squared error, so the model average estimator that minimizes the Mallows criterion also minimizes the squared error in large samples. We are concerned with two assumptions that accompany Hansen’s approach. The first is the assumption that the approximating models are strictly nested in a way that depends on the ordering of regressors. Often there is no clear basis for the ordering and the approach does not permit non-nested models which are more realistic from a practical viewpoint. Second, for the optimality result to hold the model weights are required to lie within a special discrete set. In fact, Hansen noted both difficulties and called for extensions of the proof techniques. We provide an alternative proof which shows that the result on the optimality of the Mallows criterion in fact holds for continuous model weights and under a non-nested set-up that allows any linear combination of regressors in the approximating models that make up the model average estimator. These results provide a stronger theoretical basis for the use of the Mallows criterion in model averaging by strengthening existing findings.  相似文献

Canada's experience during and after the financial crisis appears to distinguish it from its international peers. Canadian real estate sales and values experienced record increases since the global financial crisis emerged in 2008, rather than declines, and Canada did not witness any bank failures. The dominant trope concerning Canada's financial and housing markets is that they are sound, prudent, appropriately regulated and ‘boring but effective’. It is widely assumed that Canadian banks did not need, nor receive, a ‘bailout’, that mortgage lending standards remained high, and that the securitization of mortgages was not widespread. The truth, however, does not accord with this mainstream view. In fact, the Canadian financial and housing markets reveal marked similarities with their international peers. Canada's banks needed, and received, a substantial ‘bailout’, while federal policies before and after the financial crisis resulted in the massive growth of mortgage securitization and record household indebtedness. This article documents the growth of Canada's housing bubble, the history of mortgage securitization, and of government policies implemented before and after the crisis. Instead of making the Canadian financial and housing sectors more resilient and sustainable, the outcomes of state responses are best understood as regressively redistributive.  相似文献

Accounting for derivatives has created uncertainties for preparers, auditors, regulators, and users of financial statements alike. The complexity and variety of instruments as well as hedging and risk management techniques make derivatives reporting a difficult subject. Developing consistent accounting rules in this area is made even more challenging since derivatives are used in conjunction with assets and liabilities that, under the current accounting system, may be carried at historical cost, fair value, or some hybrid of fair value and historical cost. Further, derivatives are used in connection with portfolios of items as well as with economic assets and exposures that may not be recorded in financial statements under the current model.  相似文献
