On the linearity of the wage–profit relation in a Sraffa’s model: a mathematical summing-up

This paper sums up in a common analytical structure the main results, scattered in economic literature, concerning the linearity between rate of profit and real wage in a simple Sraffa’s model. The paper is mainly based on previous results of one of the two authors and on results of Miyao (Int Econ Rev 18:151–162, 1977) and Schefold (Zeitschrift für angewandte Mathematik und Physik 27:873–875, 1976a; Zeitschrift für National?konomie 36:21–48, 1976b).     

Choosing Among Regulatory Options in the United States Telecommunications Industry

We examine the determinants of the choice between rate-of-return regulation and incentive regulation in the United States telecommunications industry. We find that a state is more likely to select incentive regulation in any year: (1) when it has employed incentive regulation in the past; (2) when the Republican party controls both the executive and the legislative branches of the state government, but the Democratic party has controlled these branches historically; and (3) as the firms earnings under rate-of-return regulation increase toward the industry average. We also find that appointed regulators are more likely than their elected counterparts to revert to rate-of-return regulation.     

Development of advanced tourism studies in Holland

Bodewes, Theo, Development of Advanced Tourism Studies in Holland. Annals of Tourism Research 1981, VIII(1):35–51. The entry of tourism studies into the field of advanced education is often a difficult process. Theory and practice sometimes serve conflicting interests. In the Netherlands an option has been taken for a theoretical, multi-disciplinary approach with links to the field of practice. Within this framework, tourism is indissolubly connected with leisure and recreation, leisure being the core of studies. This implies that the universities should educate leisure economists, leisure sociologists, etc., and that advanced professional educational institutions should educate leisure experts. This paper discusses whether the problems and solutions in the Netherlands are recognizable and/or useful abroad, and whether one institution can learn from the experiences of others.     

Developing and applying a framework to evaluate participatory research for sustainability

The normative implications of participatory research imply ongoing social learning that ought to lead to personal and institutional transformation. Sustainability science also requires reflexive scientific practice in order to enable the co-generation of solutions that take account of uncertainty and multiple forms of knowledge. However, there is little published peer-reviewed material on how to assess to what degree the rhetoric regarding the benefits of participatory research are achieved in practice, particularly with regard to participatory research for sustainability. This paper outlines how linking the rationales for participatory research and for sustainability science to the principles of evaluation can deliver a conceptually coherent evaluation framework for assessment. The approach for evaluating participatory research in this context consists of framing the evaluation, i.e., setting boundaries on the subject within its social, political, environmental and institutional context and selecting appropriate criteria, methods and data sources. The application of the framework, using a summative evaluation of participatory research for sustainability in north-east Australia, illustrates its strengths and weaknesses, concluding with a consideration of its applicability to further participatory sustainability science.     

Modelling Performance Improvement and Switching Behaviour in Team Learning

Accounting educators and agencies have sought to incorporate team learning activities into conventional learning methods. The readiness-assurance process (RAP) of team learning, in which students take quizzes first as individuals and second as members of student teams, has been shown to be effective in this regard. We analyse the RAP with a fixed-effects regression model to identify the factors that contribute to performance improvement and we use ordered logit regression to estimate, probabilistically, switching behaviour within student teams. A longitudinal study was conducted over the course of a semester in which 101 undergraduate accounting students, comprising 22 teams, completed six quizzes. Within-team knowledge disparity was shown to be a significant indicator of performance improvement, and individuals appeared more likely to switch their answers after the first quiz. There were no significant effects for either performance or switching associated with demographic measures of sex and English fluency. Implications for accounting educators are discussed.     

Targeting Financial Management Training at Low‐Income Audiences

While interest in financial management training programs for low‐income persons has grown in recent years, the specific training needs of low‐income consumers have not been well articulated. This article describes needed training content for such audiences, based on review of previous research and the authors’ experiences in evaluating the Financial Links for Low‐Income People (FLLIP) program. We also illustrate how the choice of financial management training models can seriously impact the subgroups of the low‐income population who attend training, as well as the success of programs in recruiting and graduating participants. The implications of these findings both for financial management curriculum development and for the selection of program models are presented.     

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.     

Airline networks as joint goods: Implications for competition policy

This article derives a model of airline services as joint goods. Using this model, the article shows how the existence of higher fares in certain hub routes may imply the market has generated a solution to the problem of covering joint costs by having a larger proportion of those costs come from hub routes, rather than the existence of any general market failure. The model is then used to make recommendations for competition policy.     

Moment explosions in stochastic volatility models

In this paper, we demonstrate that many stochastic volatility models have the undesirable property that moments of order higher than 1 can become infinite in finite time. As arbitrage-free price computation for a number of important fixed income products involves forming expectations of functions with super-linear growth, such lack of moment stability is of significant practical importance. For instance, we demonstrate that reasonably parametrized models can produce infinite prices for Eurodollar futures and for swaps with floating legs paying either Libor-in-arrears or a constant maturity swap rate. We systematically examine the moment explosion property across a spectrum of stochastic volatility models. We show that lognormal and displaced-diffusion type models are easily prone to moment explosions, whereas CEV-type models (including the so-called SABR model) are not. Related properties such as the failure of the martingale property are also considered.
