Finite state Markov-chain approximations to highly persistent processes

The Rouwenhorst method of approximating stationary AR(1) processes has been overlooked by much of the literature despite having many desirable properties unmatched by other methods. In particular, we prove that it can match the conditional and unconditional mean and variance, and the first-order autocorrelation of any stationary AR(1) process. These properties make the Rouwenhorst method more reliable than others in approximating highly persistent processes and generating accurate model solutions. To illustrate this, we compare the performances of the Rouwenhorst method and four others in solving the stochastic growth model and an income fluctuation problem. We find that (i) the choice of approximation method can have a large impact on the computed model solutions, and (ii) the Rouwenhorst method is more robust than others with respect to variation in the persistence of the process, the number of points used in the discrete approximation and the procedure used to generate model statistics.     

Masculinities and gender-based violence in South Africa: A study of a masculinities-focused intervention programme

Violence, and particularly gender-based violence (GBV), has become an increasingly serious problem in the democratic era in South Africa. While numerous suggestions have been offered for why this is the case, a growing body of literature links the perpetration of violence and GBV to the expectations of men’s prescribed gender roles, or their masculinities. In response to this, some organisations have begun working specifically with men as a violence prevention mechanism, through the use of masculinities-focused interventions. This paper uses a South African example as a case study, looking primarily at how men who participate in the intervention understand masculinities and violence, and the impact that the intervention has on this understanding. Results suggest that violence has become largely normalised in the country, but that the intervention can play a role in beginning to problematise that normalisation.     

Amalgamations of universities:are there economics of scale or scope?

This paper estimates a multiple-output cost function for Australian universities. The estimates are used to evaluate the cost savings arising from the amalgamation of two or more institutions. These cost savings in turn are decomposed into those due to economics of scale and those due to economics of scope, using a new measure of economics of scope associated with the amalgamation of two institutions.     

What Drives the Issuance of Putable Convertibles: Risk-Shifting,Asymmetric Information,or Taxes?

This paper presents the first empirical analysis of firms’ rationale for issuing putable convertible bonds in the literature. We distinguish between three possible rationales for the issuance of putable convertibles: 1) the risk-shifting hypothesis, 2) the asymmetric information hypothesis, and 3) the tax savings hypothesis. The results of our empirical analysis can be summarized as follows. First, putable convertible issuers are larger, less risky firms, having larger cash flows, smaller growth opportunities, and lower bankruptcy probabilities as compared to ordinary convertible issuers. Second, putable convertible issuers have lower preissue market valuations, more favorable announcement effects, and better postissue operating performance when compared to ordinary convertible issuers. Third, putable convertible issuers have better postissue long-run stock return performance as compared to ordinary convertible issuers. Finally, putable convertible issuers typically have greater tax obligations and better credit ratings than ordinary convertible issuers. Overall, the results of our univariate as well as multivariate analyses provide support for the asymmetric information and tax savings hypotheses, but little support for the risk-shifting hypothesis.     

Recognition of tacit skills: sustaining learning outcomes in adult learning and work re‐entry

This paper is based on the project ‘Recognition of Tacit Skills and Knowledge in Work Re‐entry’ carried out as a part of the ESRC‐funded Research Network ‘Improving Incentives to Learning in the Workplace’. The network aims to contribute to improved practice among a wide range of practitioners. The study has investigated the part played by tacit forms of personal competences in the education, training and work re‐entry of adult learners. The models of learning produced within this study with the assistance of the Dynamic Concept Analysis method are used to provide a better understanding of individual case studies.     

An empirical investigation of interregional production relations and comparative advantage in US manufacturing, 1960–70

Hypothesized differences in mean changes in shares of European Community (EC) import markets over the period 1976-84 are tested for each of 36 less-developed countries. Means are calculated for cases in which MFN tariffs are re-established and for cases in which duty-free treatment is restored under the EC generalized system of preferences. They are compared with means for cases in which tariffs remained constant. We attempt to control for both product-specific and cyclical influences on imports. In contrast to some previous results, our findings suggest that denial (restoration) of preferential treatment, i.e. a tariff increase (decrease), has its expected negative (positive) effect.     

University – industry collaboration in R&D: the role of labor market rigidity

We investigate how R&D university – industry collaboration (R&D UIC) is influenced by labor market rigidity. While it is well-established that an educated and skilled workforce will facilitate R&D UIC, another aspect of these alliances has been under-researched: the role of labor market rigidity, in particular the difficulties employers face in hiring and firing workers. We hypothesize that the size of the R&D labor pool in a country will encourage R&D UIC, and that the ease with which employers are legally allowed to hire and fire will directly and indirectly influence R&D UIC. Integrating data from various sources, we test our model on a sample of 73 countries for which information on the size of the R&D labor pool and labor market regulations are available. We also conduct a robustness test using a different proxy for R&D labor pool on a larger sample of 109 countries. Results confirm the strong link between a country's R&D labor pool and R&D UIC, as well as direct negative impacts of hiring and firing rigidity and an indirect negative impact of hiring rigidity. The findings have implications for managers, policy makers, and researchers of R&D collaboration between universities and industry.     

Evaluating cross‐national variations in the extent and nature of informal employment in the European Union

This article evaluates critically the contrasting explanations for the cross‐national variations in the prevalence and nature of informal employment, which variously view such work as more prevalent in poorer, under‐developed economies; driven by high taxes, corruption and state interference that lead workers to exit formal employment; or driven by inadequate state intervention leading to the exclusion of workers from formal employment and state welfare provision. By analysing cross‐national variations across the European Union in the size of informal employment using indirect measurement methods and in its varying character using evidence from a 2007 Eurobarometer survey, it was found that wealthier, less corrupt and more equal economies with higher levels of labour market intervention, social protection and redistribution via social transfers have lower levels of informal employment, much of which is conducted to exit formal employment. The paper concludes by exploring the theoretical and policy implications.
