Should Higher Education Subsidies Depend on Parental Income?

In many countries, student grants, tuition fees, and subsidizedloans depend on parental income. This paper examines the efficiencyand distributional effects of such conditioning, and assesseswhether it is optimal practice when the government wants toreduce after-tax income inequality in the most efficient manner.Increasing the mean level of education among the work-forcecompresses wage differentials by level of education and therebythe pre-tax income distribution. Hence, subsidizing educationmay be part of an optimal redistribution policy. However, educationsubsidies mainly benefit high-ability students, limiting theirredistributive virtues. Conditioning education subsidies onparental income may enable the government to reduce inframarginalsubsidies, mainly benefiting high-ability students, while preservingthe marginal subsidy, and thus the favourable effect on themean education level which leads to wage compression.     

THE ECONOMICS OF COMMUTING AND THE URBAN LABOUR MARKET

ABSTRACT. The spatial distribution of households and firms, or urban spatial structure, is a core element of the study of urban economics and the crucial determinant of commuting patterns. This paper examines developments in the analysis of urban spatial structure and commuting are related to the urban labour market—that is the analysis of labour supply and labour demand in a spatial context. These developments have been overlooked in the traditional approach to urban structure and commuting where most attention has been devoted to the markets for land and housing rather than the market for labour. Yet a little reflection suggests that the labour market might have a great deal to do with the location decisions of households and firms, and hence with commuting patterns. We argue that much criticism of the economic analysis of urban structure and commuting can be addressed by explicit incorporation of the labour market into the conventional model of urban location. This criticism includes findings that the theory cannot explain the tendency for richer households to live farther from the central business district and commute farther to work (Wheaton, 1977) and findings of substantial unexplained or 'wasteful' commuting according to conventional theory (Hamilton, 1982). The paper begins by outlining the basic model of residential location and commuting (Section 2). We then consider extensions that involve the introduction of labour supply decisions and which determine the value of commuting time (Section 3). More recent extensions involve the introduction of decentralized workplaces (Section 4) and, logically, the issues of job search and migration (Section 5). We conclude with a summary of the progress in incorporating labour market behaviour into the analysis of urban structure and commuting and our suggestions for further research in this area.     

Who's afraid of an open insurance market?

Although until recently foreign markets were profitable only for insurers dealing with commercial risks, it may be assumed that the development of the free insurance market will have an impact also on the insurance of consumer risks. The insurer may remain passive in the hope that the prospective policy-holder will take the initiative to cross the border, or he may actively involve himself by advertising his services in the foreign country. In these endeavours, the insurer will need the support of the insurance intermediary. It is therefore to be expected that the popularity of the so-called broker's cover will increase vastly. This will not enhance the transparency of the insurance market. The option, open to the EC Member States, to decide whether or not to go for freedom of choice of law rule, does not make it easier to coordinate and harmonize private international insurance law among the Member States.     

Human Capital Management: New Possibilities in People Management

In addition to the traditional personnel and human resource management (HRM), there is a need for a new approach to personnel management, which we will call Human Capital Management (HCM). HCM emphasises an alignment between the individual and the organization and in our view offers the challenge and the key to successful management in the future.     

Measuring the Impact of Direct and Indirect R&D on the Productivity Growth of Industries: Using the Yale Technology Concordance

This paper investigates the impact of direct and indirect R&D on the productivity growth of 30 French industries during the period 1978–92. The main aim of this paper is to assess the appropriateness of the Yale Technology Concordance (YTC) as a proxy for indirect R&D flows. We compare the effect on productivity growth of the Yale proxy with the traditional proxy based on goods input–output flows, and assess their suitability for different groups of industries. Results indicate that the indirect YTC proxy performs slightly better than the traditional proxy, as a result of superior performance in the high-tech and service sectors in particular.     

Nonparametric estimators of the bivariate survival function under random censoring

A large number of proposals for estimating the bivariate survival function under random censoring have been made. In this paper we discuss the most prominent estimators, where prominent is meant in the sense that they are best for practical use; Dabrowska's estimator, the Prentice–Cai estimator, Pruitt's modified EM-estimator, and the reduced data NPMLE of van der Laan. We show how these estimators are computed and present their intuitive background. The asymptotic results are summarized. Furthermore, we give a summary of the practical performance of the estimators under different levels of dependence and censoring based on extensive simulation results. This leads also to a practical advise.     

Firm growth during infancy

In this paper, we study the post-entry patterns of survival and growth of firms established in Portuguese manufacturing in 1983. Our data suggest the existence of a highly turbulent economy, with a very large number of small firms being created, but a great proportion of new firms disappearing in the first years subsequent to their birth. Survivors, however, grow quite fast and we found that small firms grow faster than their larger counterparts. Moreover, we found that the growth decision of firms is affected by a firm specific component, which is also correlated with firm size. These two effects are oppositely signed and, therefore, estimates that fail to take this firm specific effect into account are likely to be strongly biased towards zero.
