Slow productivity growth in the building and construction industry is often put forward as the cause of rising building costs. In view of the importance of the building sector in the national economy, factual empirical knowledge is hard to come by. The few studies found are usually carried out on a sectoral level and based on time-series data. However, to come to grips with the real causes for slow productivity growth, one has to analyze at the microlevel of actual decision making. Our study is based on establishment data for 1986. The method of analysis is the deterministic frontier approach. The efficiency distributions show large variations with average structural efficiency about 20 percent. Thus, there is significant scope for productivity improvement if average performance can catch up with best practice.The refereeing process of this article was handled through T.G. Cowing.  相似文献

Although the empirical pattern of industry shakeout has been documented for many manufacturing industries, we know little about the processes by which market structure evolves in non-manufacturing service industries. This paper establishes detailed empirical observations about the consolidation of a single non-manufacturing industry, the wholesale distribution of pharmaceuticals. These observations are used to explore differences between manufacturing and wholesaling in both the patterns and explanations for consolidation and analyze the explanatory power of theories that link consolidation to technological change. The analysis demonstrates that theories developed to explain consolidation in new manufacturing industries have varying degrees of applicability to the consolidation of drug wholesaling. The observed patterns of exit, innovation, and growth suggest important modifications to evolutionary theories of market structure.  相似文献

This study aims to explore the motor insurance market's attitude towards usage‐based insurance (UBI), and thus its readiness for a launch in the near future. Data on client perception was collected using a structured questionnaire. On the basis of this, an initial selection of factors, other than income, that could influence the declared attitude of drivers was demonstrated showing that it is primarily dependent on certain demographic characteristics like their age, sex, or place of residence. A strong relationship was also demonstrated with respect to the intensity of the vehicle's use, to the amount of the insurance premium they have paid, and to the self‐assessment of the respondents' driving skills. Clients are likely to accept the concept of UBI once implemented, but that they are not ready yet to give up the traditionally used methods of premium calculation. Their attachment to discounts granted can be very strong in particular to the no‐claims bonus.  相似文献

Attempts are being made to construct a “new local economics” and important claims are being made on its behalf. In present circumstances, its contribution, though with some valuable achievements as John Benington has shown, must nevertheless be marginal. The task is to gain the maximum leverage from minimal resources, and this article suggests that the key priorities should be to use local authorities' influence as purchasers, employers and investors.  相似文献

Most studies of the impacts of global warming policy have been performed at the national level. However, national averages obscure the fact that some regions may be affected much more than others. We formulated a regional computable general equilibrium model to analyze the impact of a carbon tax on the Pennsylvania economy. The model incorporates special features relating to labor mobility, trade and energy substitution for this purpose. Our results indicate significant negative overall impacts on the Pennsylvania economy, primarily because it is a major producer and user of fossil fuels, especially coal, and because it is highly industrialized. Sensitivity analyses on key parameters and model assumptions indicate that our results are robust.  相似文献

Over the past decade, input–output structural decomposition analysis (SDA) has developed into a major analytical tool. We review the development of SDA and its relationship to other methodologies. We present the fundamental principles of alternative approaches to deriving SDA estimating equations and explore the various decompositions of changes in IO tables. We also identify several complications and unresolved issues. Most importantly, we find that a rigorous grounding in economic theory is lacking for SDA, but we are able to offer some suggestions as to how it might be established.  相似文献

The first 150 words of the full text of this article appear below. Spring at last. Here in Montreal, the transition from winteris particularly delicious. There is more light, the world looksless grey, and the trepidation that another storm may be aroundthe corner is put away with the winter tires. In this issueof JFEC, the editors appear to be underscoring seasonal changein an issue whose unifying theme involves parameter and modelstability. Parameter stability is an important issue in econometrics. Achanging economic environment may be captured by allowing theparameters of a reduced form model to vary to reflect changingconditions. The challenge for the econometrician is to constructmodels that do more than reflect changes in an ad hoc manner.For want of more insightful approaches, the challenge is oftensidestepped in practice by focusing on shorter samples whereno structural change can be assumed to have occurred. However,in so constricting the sample size, . . . [Full Text of this Article]  相似文献

We estimate the effect of minimum wages on employment duration using event history data from the 1988-1994 rounds of the National Longitudinal Survey of Youth. Existing literature takes two alternative tracks: Some studies predict reduced turnover due to rents created by minimum wages, others focus on the expected increase in turnover due to reduced job amenities and imperfect information. We find that for men, the net effect of a minimum wage depends on its magnitude relative to the typical wage in the local labor market. We find some evidence that where the minimum wage is low, separation rates for men hired at the minimum wage are reduced. We also find that as the relative value of the minimum wage rises, separation hazards increase. We interpret these findings as evidence that rents may accrue to minimum wage workers, but that the job matching process is undermined when the minimum wage binds.  相似文献
