The truncated Poisson regression model is used to arrive at point and interval estimates of the size of two offender populations, i.e. drunk drivers and persons who illegally possess firearms. The dependent capture–recapture variables are constructed from Dutch police records and are counts of individual arrests for both violations. The population size estimates are derived assuming that each count is a realization of a Poisson distribution, and that the Poisson parameters are related to covariates through the truncated Poisson regression model. These assumptions are discussed in detail, and the tenability of the second assumption is assessed by evaluating the marginal residuals and performing tests on overdispersion. For the firearms example, the second assumption seems to hold well, but for the drunk drivers example there is some overdispersion. It is concluded that the method is useful, provided it is used with care.  相似文献

Recent approaches to sustainable development leave much room for policies at a local level. In fact, it is becoming evident that targets such as increasing resource productivity, preserving natural cycles, or extending the present level of welfare, are best pursued within the confines of a local area. In particular, environmental changes are best brought about by considering local systems of firms as cornerstones of cooperative strategies and using data on materials and energy use in physical terms. In this paper, an enterprise input–output model is developed for an industrial district, i.e. a local group of firms specialized in the production of a single final output. The model allows for a detailed quantitative analysis of materials and energy flows and the consequent generation of waste and pollution. As a planning tool, the model may be used to evaluate alternative scenarios, such as the possibility of re- using waste taking account of sustainability requirements. An empirical case study applies the model to an industrial district in Southern Italy producing leather sofas.  相似文献

Regulating Banks through Market Discipline: A Survey of the Issues   总被引:2,自引:0,他引:2  
Abstract.  The interest in the application of market discipline to regulate the financial industry has boomed recently due to the proposed New Capital Accord. This paper reviews the potential role market discipline can play in financial regulation. We start with a discussion of the rationale for financial regulation and with a brief history of the current regulatory mechanisms. Next, a definition of market discipline as a regulatory mechanism is advanced. We evaluate the disciplining power various market participants have. Finally, we argue that more external risk management disclosure is a condition sine qua non in order to enable market discipline as a regulatory mechanism. In this respect, the Basle Committee has taken the right approach.  相似文献

In a number of constitutions, in article 16.3 of the International Bill of Human Rights and in article 23.1 of the International Covenant on Economic, Social and Cultural Rights it is laid down that the family is the natural and fundamental group unit of society and is entitled to protection by society and the State. The following exposition aims to explain the monetary family policy and the extent of monetary transfers for the protection of families in the member countries of the European Community (EC).  相似文献

The degree of spatial market integration in European Community agricultural product markets is investigated. The methodology is based on co-integration analysis. A two-step testing procedure is applied to test the existence of the ‘Law of One Price’ which should be in force if these markets are truly integrated. The results show that market integration has not been achieved in a number of cases even when MCAs are subtracted from the price series used.  相似文献

WORLD OUTLOOK     
Events in the Gulf have finally brought an end to the world economic boom of the last eight years. The oil price shock itself is only partly responsible for the downturn. The previous tightening of monetary policy in the face of inflationary pressures and the end of a rapid period of credit and asset price expansion had severely weakened the ability of some economies to respond to the shock. This is reflected in the diversity of response, most obviously in the United States where Fed fine tuning and the credit crunch have already weakened the economy. The rise in oil prices has led to a sudden collapse in consumer confidence and a swift cutback in output. Although we do not expect the recession to be deep, the financial problems will delay recovery. The Japanese economy was already in financial difficulties before the shock, although the real economy was stronger and here we expect a sharp deceleration from almost 6 per cent growth last year to around 3.5 per cent. In contrast the German economy, partly shielded by the substantial appreciation of the DM over the last year, has been affected less by the oil price shock and we expect the consumer and investment boom to continue this year as the economies merge. This provides a welcome boost to other European economies.  相似文献

If a tax on energy affects the demand for a nondurable good, the stock of a durable good, and the proportion of the energy consumption per unit of service of the durable good, an integrated approach for investigating consumer demand for durables and nondurables is required. The purpose of this paper is to employ the concept of a variable expenditure function with quasi-fixed durable goods as arguments in order to derive a demand system for nondurable goods in prices of the nondurables, in the stocks of durables, and in variable expenditure. From the envelope condition desired stocks of durables can be calculated and investment demand for durables can be determined. For an application we choose a variable expenditure function based on the almost ideal demand specification, and evaluate alternative environmental policy measures using the equivalent variation for comparing the welfare effects.  相似文献

The New Growth Theory and Coasean Economics: Institutions to Capture Externalities. — This paper presents the main theoretical arguments which lead many adherents of the New Growth Theory to the conclusion that externalities in research and development are important for economic growth and warrant government subsidies. In contrast, the authors point to private institutions like associations, company structures and industry clusters which can capture such externalities. An international comparison of private R&;D investment and special features of institutions in Switzerland and Japan are in line with this hypothesis. Thus, the argument for R&;D subsidies made by the New Growth Theory is considerably reduced.  相似文献
