Is low unionisation in the British hospitality industry due to industry characteristics?

Low recognition and concomitant characteristics of a union presence are key factors associated with very low union membership in the British hospitality industry (HI) but there may be exceptional factors in the HI that render it more amenable to union membership after standard explanations are accounted for. Although the lessons for unions are to seek greater employer legitimacy at the same time as securing membership, recognition rates would have to increase by six times to double the rate of union density in the HI and satisfy ‘frustrated’ demand for unionisation. Questions are also raised about the utility of the statutory recognition procedures and current union organising and retention strategies.     

From public to private: Has employment practice changed in Bulgarian hotels?

This study finds a clear shift towards the importance of HRM strategy and the need for change towards service quality [Vachkova, E., Gaidarov, M. (2001). Management of Human Resources in the Global Society, Banki Investicii Pari, 1. Sofia, Bulgaria, pp. 29–35] in Bulgarian hotels 15 years into the post-socialist era. This is not matched by a significant change in improved employment flexibility, more effective career development, improved communications and management style and, most problematic of all, improved training and development. Although managerial statements about the importance of HRM may be rhetorical, the balance of evidence suggests that the legacy of cultural and institutional effects in Bulgaria remains strong and may have created a vacuum that prevents managers from developing the ability and know-how to initiate change, and by implication, improve firms’ performance.     

The multi-state latent factor intensity model for credit rating transitions

A new empirical reduced-form model for credit rating transitions is introduced. It is a parametric intensity-based duration model with multiple states and driven by exogenous covariates and latent dynamic factors. The model has a generalized semi-Markov structure designed to accommodate many of the stylized facts of credit rating migrations. Parameter estimation is based on Monte Carlo maximum likelihood methods for which the details are discussed in this paper. A simulation experiment is carried out to show the effectiveness of the estimation procedure. An empirical application is presented for transitions in a 7 grade rating system. The model includes a common dynamic component that can be interpreted as the credit cycle. Asymmetric effects of this cycle across rating grades and additional semi-Markov dynamics are found to be statistically significant. Finally, we investigate whether the common factor model suffices to capture systematic risk in rating transition data by introducing multiple factors in the model.     

The effects of the minimum wage in Brazil on the distribution of family incomes: 1996–2001

The Brazilian economy has long relied on the minimum wage, having first implemented a minimum in 1940. Shortly after taking office in 2003, Brazil's President raised the minimum wage by 20% and promised to double the value of the minimum wage before his term ends in 2006. The usual rationale for minimum wage increases is to bring about beneficial changes in the income distribution, by raising incomes of poor and low-income families. The goal of this paper is to evaluate the efficacy of the minimum wage in Brazil in bringing about these changes in the income distribution. We examine data drawn from Brazil's major metropolitan areas, studying the years after Brazil's hyper-inflation ended. The estimates provide no evidence that minimum wages in Brazil lift family incomes at the lower points of the income distribution; if anything some of the evidence points to adverse effects on lower-income families.     

A systematic mapping study of process mining

This study systematically assesses the process mining scenario from 2005 to 2014. The analysis of 705 papers evidenced ‘discovery’ (71%) as the main type of process mining addressed and ‘categorical prediction’ (25%) as the main mining task solved. The most applied traditional technique is the ‘graph structure-based’ ones (38%). Specifically concerning computational intelligence and machine learning techniques, we concluded that little relevance has been given to them. The most applied are ‘evolutionary computation’ (9%) and ‘decision tree’ (6%), respectively. Process mining challenges, such as balancing among robustness, simplicity, accuracy and generalization, could benefit from a larger use of such techniques.     

Probing the basis for differential pay practices of younger workers in low paying hospitality firms

Understanding the basis for differential pay practices by age is an important policy issue now that claims for pay discrimination on grounds of age may be mounted. Difficulties in determining the relative job worth and personal worth of workers in particular age groups are highlighted. We identify a need to develop a practical mechanism for assessing the validity of age‐related pay differences in keeping with contemporary notions of jobs and skills that will provide a basis for employers to demonstrate objective justification that their employment practices are not discriminatory. More comprehensive and wide‐ranging research is necessary to differentiate age‐related pay practices and develop further theoretical insights.     

Optimal demand policies against stagflation

Zusammenfassung Optimale Nachfragepolitik zur Bek?mpfung der Stagflation. — Der Aufsatz besch?ftigt sich mit der Wahl einer optimalen Gesamtnachfrage-Politik als Antwort auf einen inflation?ren Schock — optimal in dem Sinne, da\ die Volkswirtschaft zur Vollbesch?ftigung und Preisstabilit?t auf einen Pfad zurückgeführt wird, der die sozialen Kosten minimiert. Es wird die Ansicht vertreten, da\ die Kosten eines gegebenen Stabilisierungspfades proportional sind zu den über die Zeit aufsummierten Abweichungen der Inflationsrate und der Arbeitslosenquote von den langfristigen Zielwerten. Auf der Grundlage einer sehr allgemeinen Formulierung der Phillips-Kurve wird die optimale wirtschaftspolitische Antwort auf einen Inflationsschock analysiert und gezeigt, da\ sie gew?hnliche ?Turnpike?-Eigenschaften besitzt. Dieser Ansatz wird veranschaulicht, indem er auf die USA für den Zeitraum 1971–1975 angewandt wird, wobei die Sensitivit?t des optimalen Pfades in bezug auf alternative Wohlfahrts-Bewertungen und Ansichten hinsichtlich der Natur des Trade-off untersucht wird.

Résumé Les politiques de demande optimum contre la stagflation. — Cet article a pour sujet la selection d’une politique de demande agrégée optimum en réponse à un choc — optimum de manière qu’elle reconduit l’économie au plein emploi et à la stabilité de prix le long d’un sentier d’inflation-ch?mage minimisant des frais sociaux de ?welfare?. Nous arguons que les frais du chaque sentier donné de stabilisation peuvent être pris comme proportioneis à l’excès d’inflation et de ch?mage au-dessus du but à long terme, cumulé sur le sentier. En se fiant à une expression très générale de la ?courbe de Phillips? l’article analyse et démontre la réponse de politique optimum à un choc inflationniste pour exhiber des simples ?barrières? propriétés. L’approche est illustrée par l’application sur les E. U. pour la période de 1971 à 1975. Elle explore la sensibilité du sentier optimum aux évaluations alternatives de ?welfare? et aux vues de la nature du ?trade-off?.

Resumen Políticas óptimas de demanda contra la estagflación. — Este artículo se ocupa de la selección de una política de demanda agregada óptima en respuesta a un ?shock? óptimo inflacionario en el sentido que devuelve el pleno empleo y la estabilidad de precios a la economía a través de una trayectoria de inflación-desempleo minimizando los costos sociales de bienestar. Se argumenta que el costo de cualquier trayectoria de estabilización dada puede tomarse como proporcional al exceso de inflación y desempleo por sobre la meta de largo plazo, acumulado a través de la trayectoria. Basándose sobre una formulación muy general de la ?curva de Phillips? se analiza la respuesta de política óptima a un ?shock? inflacionario y se muestra que exhibe propiedades simples de Camino de portazgo. El enfoque se ilustra aplicándolo a los EEUU para el período 1971–75, investigando la sensibilidad de la trayectoria óptima con respecto a evaluaciones de bienestar alternativas y apreciaciones sobre la naturaleza del ?trade-off?.

     

Beyond the existence proof: ontological conditions, epistemological implications, and in-depth interview research

In-depth interviewing is a promising method. Alas, traditional in-depth interview sample designs prohibit generalizing. Yet, after acknowledging this limitation, in-depth interview studies generalize anyway. Generalization appears unavoidable; thus, sample design must be grounded in plausible ontological and epistemological assumptions that enable generalization. Many in-depth interviewers reject such designs. The paper demonstrates that traditional sampling for in-depth interview studies is indefensible given plausible ontological conditions, and engages the epistemological claims that purportedly justify traditional sampling. The paper finds that the promise of in-depth interviewing will go unrealized unless interviewers adopt ontologically plausible sample designs. Otherwise, in-depth interviewing can only provide existence proofs, at best.
