Financing Transit Systems Through Value Capture

A bstract .   Much of the literature on value capture reports empirical findings on the incidence of rising land values related to distance from a transit stop following the installation of rail transit improvements. This annotated bibliography shows that the elevated value effects of transit access are well documented. The authors maintain that it is now time for transit/land-use research to move from hypothesis testing to practical applications of value capture . Longitudinal models can help predict land-value increments over a period of time, yielding estimates of the total capturable revenues that would support the debt financing of transit improvement projects.

Unpacking the client(s): Constructions, positions and client–consultant dynamics

Research on management consultancy usually emphasizes the role and perspective of the consultants. Whilst important, consultants are only one element in a dynamic relationship involving both consultants and their clients. In much of the literature, the client is neglected, or is assumed to represent a distinct, immutable entity. In this paper, we argue that the client organisation is not uniform but is instead (like organisations generally) a more or less heterogeneous assemblage of actors, interests and inclinations involved in multiple and varied ways in consultancy projects. This paper draws upon three empirical cases and emphasizes three key aspects of clients in the context of consultancy projects: (a) client diversity, including, but not limited to diversity arising solely from (pre-)structured contact relations and interests; (b) processes of constructing ‘the client’ (including negotiation, conflict, and reconstruction) and the client identities which are thereby produced; and (c) the dynamics of client–consultant relations and how these influence the construction of multiple and perhaps contested client positions and identities.     

Flexible work practices and human resource management: a comparison of South African and foreign owned companies

This study compares the use of flexible work practices in wholly owned South African (SA) companies with that in foreign-owned companies. Data were obtained from questionnaire results of a study conducted by Horwitz and Franklin (1996) of flexible work practices in SA organizations. The questionnaire was used as part of a collaborative research project involving three countries (Brosnan et al ., 1996). It was found that SA-owned companies use certain flexible work practices to a lesser extent than foreign-owned companies. This was found to be the case particularly in the use of numerical forms of flexibility, such as sub-contractors/consultants and the use of temporary employees. Use of subcontractors/consultants and temporary staff agencies was found to be the greatest in partially foreign-owned companies. A larger proportion of foreign-owned companies have lower labour costs than do SA-owned companies. This has, however, not been as a result of the greater use of flexible work practices. Foreign-owned companies make more joint decisions with unions than do SA-owned companies when changing work practices.     

Understanding prediction intervals for firm specific inefficiency scores from parametric stochastic frontier models

This paper makes two important contributions to the literature on prediction intervals for firm specific inefficiency estimates in cross sectional SFA models. Firstly, the existing intervals in the literature do not correspond to the minimum width intervals and in this paper we discuss how to compute such intervals and how they either include or exclude zero as a lower bound depending on where the probability mass of the distribution of \( u_{i} |\varepsilon_{i} \) resides. This has useful implications for practitioners and policy makers, with greatest reductions in interval width for the most efficient firms. Secondly, we propose an ‘asymptotic’ approach to incorporating parameter uncertainty into prediction intervals for firm specific inefficiency (given that in practice model parameters have to be estimated) as an alternative to the ‘bagging’ procedure suggested in Simar and Wilson (Econom Rev 29(1):62–98, 2010). The approach is computationally much simpler than the bagging approach.     

Dividend timing and behavior in laboratory asset markets

Summary. This paper investigates the effect of dividend timing on price bubbles and endogenous expectations in twenty-six laboratory asset markets. In ten "A1" markets, a single dividend is paid at the end of the trading horizon. In nine "A2" markets, dividends are paid at the end of each trading period. In seven "A3" markets, some of the dividends are paid at the end of the trading horizon, and the rest are paid on a per-period basis. The results indicate that price bubbles are most likely in A2 markets, less likely in A3 markets, and least likely in A1 markets. Six distinct hypotheses are considered. The data suggest that the concentration of dividend value at a single point in time helps to create common expectations, and thus significantly reduce the incidence of bubbles. Also, the results underscore the difficulty facing econometric tests on field data where fundamental value has to be approximated.
