REFORMING PROPERTY RIGHTS IN LAND AND TENANCY

This article examines the nature and distribution of propertyrights in land and how they are changing under economic anddemographic pressures. It also analyzes the practical chancesof success of several alternative forms of policy interventionto redistribute property rights and regulate tenancy. This analysisbegins with the political economy of land reform in the twentiethcentury. It draws a distinction between reforms precipitatedby social upheaval (defeat in war, social revolution, or nationalliberation) and those that occur in "normal" times, when thesocial and political order is more secure. It is argued thatthe former have been much more important and, drawing on examples,that the latter face formidable obstacles. In this connection,it is proposed that a tax reform which does away with the highlyselective subsidies and exemptions that benefit the rich andinflate the price of land should be undertaken first. Then,when land prices have fallen, compulsory purchase of land forredistribution, at close to fair market value to ensure itspolitical acceptability, would not entail an intolerable fiscalburden. Where tenancy is concerned, it is argued that this institutionis commonly a socially useful market response, which providesopportunities for the fuller employment of family resourcesand, over the long run, for individual mobility. Thus interventionsdesigned to inhibit tenancy directly or to transfer ownership-likerights to existing tenants may result in heavy costs, especiallyfor future cohorts of would-be tenants.      

Internationalisation Processes,Networking and Local Embeddedness in Technology-Intensive Small Firms

The paper argues that technology-intensive small firms often need to internationalise their activities, and especially sales, at a very early stage of their development because of the limited and global nature of the technological market niche which they have been set up to exploit. From a survey of 100 such firms in the Cambridge and Oxford regions, it demonstrates that many technology-based smaller firms are engaged in a range of international networks and internationalisation processes, including internationalisation of markets, research collaboration, labour recruitment, ownership and facilities location. Technology-intensive firms reporting high levels of internationalisation also differ significantly from those which are more nationally-oriented, for example in terms of size, age, research intensity, university links, and innovativeness. There are also differences with respect to recent growth rates. Finally, the paper demonstrates that far from substituting international for local networks, technology-intensive firms which have achieved high levels of internationalisation in fact also exhibit above-average levels of local networking with respect to research collaboration and intra-industry links. Internationalisation therefore appears to be grounded or embedded in successful local networking and research and technology collaboration.     

Separation in Cointegrated Systems and Persistent-Transitory Decompositions

The notion of separation in cointegrated systems helps identifying possible sub-system structures that may reduce the complexity of larger systems by yielding a more parsimonious representation of the times series. In this paper we demonstrate that although the subsystem cointegration analysis in such systems can be conducted in case of both completely and partially separated systems, the dual approach, i.e. calculation of the common stochastic trends, may turn out to yield properties of the trends that differ depending upon the type of separation under consideration. In particular, we demonstrate how persistent-transitory (P-T) decompositions and long- and short-memory factorizations of a multivariate time series will interact across systems when considering the presence (or absence) of different types of separation. Generalizations to non-linear error correction models are briefly discussed.     

Common factors in conditional distributions for bivariate time series

A definition for a common factor for bivariate time series is suggested by considering the decomposition of the conditional density into the product of the marginals and the copula, with the conditioning variable being a common factor if it does not directly enter the copula. We show the links between this definition and the idea of a common factor as a dominant feature in standard linear representations. An application using a business cycle indicator as the common factor in the relationship between U.S. income and consumption found that both series held the factor in their marginals but not in the copula.     

Employer size–wage effects: evidence from matched employer–employee survey data in the UK

This paper employs a random sample of matched employer–employee data from the UK to test seven possible explanations for the positive relationship between employer size and pay. Individual wage equations show a large employer size–wage premium. We then control for a range of establishment-level variables, based on seven hypotheses typically advanced to explain this premium. Each establishment-level factor reduces the wage premium, but a sizeable premium nonetheless remains. In adjudicating on these hypotheses, we find a strong association between the internal labour market and the employer size–wage premium. This finding supports the theory that the employer size–wage effect may be due to the higher costs of turnover or monitoring in larger firms. However, we find contrasting effects for public versus private sector establishments.     

An Economist's Comment on Philosophico-Economic Relationships

In this journal, Welch and Mueller (WM) (2001) demonstrated a classificatory method for conceptualizing relationships between religion and economics. No judgement can be drawn from WM as to which of their four classifications might be a, or the, correct one. They conclude that the relationships are “both complex and controversial”, and that before any assessment can be apprehended adequately of how the two fields interact, “the permutations and subcategories implied by the system” used need to be identified and explored more thoroughly. This paper pursues that path, but argues that a more determinate verdict than WM's is possible. Here, an alternative interpretation of the relationship between religion and economics is investigated, in which WM's categories are assessed. In the alternative, WM's four classes are not taken to possess equal intellectual merit, as they appear to be. Using more current and comprehensive definitions of religion than WM's, a case is constructed that three of their four categories possess greater intellectual value than the remaining one. These three are here collapsed into one new mega-category regarded as that most validly describing the relationship between religion and economics.
