Methods and tools for integrated assessment of land use policies on sustainable development in developing countries

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem.     

Hedonic price equilibria, stable matching, and optimal transport: equivalence, topology, and uniqueness

Hedonic pricing with quasi-linear preferences is shown to be equivalent to stable matching with transferable utilities and a participation constraint, and to an optimal transportation (Monge–Kantorovich) linear programming problem. Optimal assignments in the latter correspond to stable matchings, and to hedonic equilibria. These assignments are shown to exist in great generality; their marginal indirect payoffs with respect to agent type are shown to be unique whenever direct payoffs vary smoothly with type. Under a generalized Spence-Mirrlees condition (also known as a twist condition) the assignments are shown to be unique and to be pure, meaning the matching is one-to-one outside a negligible set. For smooth problems set on compact, connected type spaces such as the circle, there is a topological obstruction to purity, but we give a weaker condition still guaranteeing uniqueness of the stable match.     

Multiple foci of commitment in a professional service firm: balancing complex employment relations

Employees of professional service firms (PSFs) have attachments to multiple groups, which may be either compatible or conflicting: their employer, their clients and their profession. We analyse the antecedents of commitment to these three foci based on a survey of 510 employees in a large PSF in Norway. The main findings are as follows: (1) low quality of internal work relations is negatively associated with employer commitment and draws employees towards external foci of commitment – the clients and the profession; (2) role conflict is associated with stronger commitment to the client organisation and the profession; and (3) autonomy and transferability of skills are associated with stronger commitment to the profession, but does not undermine commitment to the employer. The article contributes to our understanding of the conditions under which employees identify with external groups and when commitment to the employer may be compromised. The findings have implications for how managers can help to increase the commitment of employees involved in complex employment relations.     

Modelling the demand for housing over the life cycle

We model individual demand for housing over the life cycle, and show the aggregate implications of this behaviour. Individuals delay purchasing their first home when incomes are low or uncertain. Higher house prices lead households to downsize, rather than to stop being owners. Fixed costs (property transactions taxes) have important impacts on welfare (a wealth effect) and house purchase decisions (substitution effect). In aggregate, positive house price shocks lead to consumption booms among the old but falls in consumption for the young, and reduced housing demand; positive income shocks lead to consumption booms among the young and increased housing demand.     

THE HOUSING STOCK,HOUSING PRICES,AND USER COSTS: THE ROLES OF LOCATION,STRUCTURE, AND UNOBSERVED QUALITY

Which housing characteristics are important for understanding homeownership rates? How are housing characteristics priced in rental and owner-occupied markets? What can answers to these questions tell us about economic theories of homeownership? Using the English Housing Survey, we estimate a selection model of property allocations to the owner-occupied and rental sectors. Structural characteristics and unobserved quality are important for selection. Location is not. Accounting for selection is important for rent-to-price ratio estimates and explains some puzzling correlations between rent-to-price ratios and homeownership rates. These patterns are consistent with, among others, hypotheses of rental market contracting frictions related to housing maintenance.     

Externalizing the core: Firms' use of employment intermediaries in the information and communication technology industries

Recent research suggests that nonstandard employment relations may be a source of innovation for the firm. In this article, we analyze firms' strategic correlates and perceived benefits from using two types of employment in‐termediaries—consulting firms and temporary help agencies—in their core activities. Organizations with an innovation strategy are more likely to use consulting firms in their core activities, while organizations that compete on the basis of low cost are more apt to use temporary help agencies. Moreover, managers say that consulting firms are more likely than temporary help agencies to provide them with special competencies in their core activities. © 2007 Wiley Periodicals, Inc.
