An Anatomy of Commodity Futures Risk Premia

Abstract: We identify two types of risk premia in commodity futures returns: spot premia related to the risk in the underlying commodity, and term premia related to changes in the basis. Sorting on forecasting variables such as the futures basis, return momentum, volatility, inflation, hedging pressure, and liquidity, results in sizable spot premia in the high-minus-low sorted portfolios between 5% and 14% per annum and term premia between 1% and 3% per annum. We show that a single factor, the high-minus-low portfolio from basis sorts, explains the cross-section of spot premia. Two additional basis factors are needed to explain the term premia.

The Predictive Validity of the Tilburg Frailty Indicator: Disability, Health Care Utilization, and Quality of Life in a Population at Risk

Abstract: Purpose: To assess the predictive validity of frailty and its domains (physical, psychological, and social), as measured by the Tilburg Frailty Indicator (TFI), for the adverse outcomes disability, health care utilization, and quality of life. Design and Methods: The predictive validity of the TFI was tested in a representative sample of 484 community-dwelling persons aged 75 years and older in 2008 (response rate 42%). A subset of all respondents participated 1 year later (N = 336, 69%) and again 2 years later (N = 266, 55%). We used the TFI, the Groningen Activity Restriction Scale assessing disability, seven indicators of health care utilization, and a brief version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF). The WHOQOL-BREF was assessed in 2008 and 2010; all others were assessed in 2008, 2009, and 2010. Results: T he predictive validity of the TFI assessed in 2008 for disability, health care utilization, and quality of life was corroborated by (a) medium to very large associations of frailty with adverse outcomes 1 or 2 years later; (b) mostly good to excellent area under the curve of total frailty; and (c) an increase in predictive accuracy of most adverse outcomes, even after controlling for that same adverse outcome in 2008, and life-course determinants and multimorbidity. Physical frailty was

Do Managerial Incentives Drive Cost Behavior? Evidence about the Role of the Zero Earnings Benchmark for Labor Cost Behavior in Private Belgian Firms

Abstract: This study investigates the influence of managerial incentives to meet or beat the zero earnings benchmark on labor cost behavior of private Belgian firms. We posit that relative to managers of firms reporting healthy profits, managers meeting or beating the zero earnings benchmark will increase labor costs to a smaller extent when activity increases and decrease labor costs to a larger extent when activity decreases. This should take the form of more symmetric labor cost behavior for firms that report a small profit. Our findings are consistent with this prediction. Using detailed employee data, we show that managers of firms reporting a small profit focus on firing employees who are relatively low cost to fire. To protect their reputation in the labor market, managers of other firms, particularly those reporting healthy profits, limit the numbers of dismissals and react to activity changes by changing the number of hours that employees work.

Beyond languages, beyond modalities: transforming the study of semiotic repertoires

Abstract: This paper presents a critical examination of key concepts in the study of (signed and spoken) language and multimodality. It shows how shifts in conceptual understandings of language use, moving from bilingualism to multilingualism and (trans)languaging, have resulted in the revitalisation of the concept of language repertoires. We discuss key assumptions and analytical developments that have shaped the sociolinguistic study of signed and spoken language multilingualism as separate from different strands of multimodality studies. In most multimodality studies, researchers focus on participants using one named spoken language within broader embodied human action. Thus while attending to multimodal communication, they do not attend to multilingual communication. In translanguaging studies the opposite has happened: scholars have attended to multilingual communication without really paying attention to multimodality and simultaneity, and hierarchies within the simultaneous combination of resources. The (socio)linguistics of sign language has paid attention to multimodality but only very recently have started to focus on multilingual contexts where multiple sign and/or multiple spoken languages are used. There is currently little transaction between these areas of research. We argue that the lens of semiotic repertoires enables synergies to be identified and provides a holistic focus on action that is both multilingual and multimodal.
