Investor behaviour and reaching for yield: Evidence from the sterling corporate bond market

We provide evidence on how corporate bond investors react to a change in yields, and how this behaviour differs in times of market‐wide stress. We also investigate ‘reaching for yield’ across investor types, as well as providing insights into the structure of the corporate bond market. Using proprietary sterling corporate bond transaction data, we show that insurance companies, hedge funds and asset managers are typically net buyers when corporate bond yields rise. Dealer banks clear the market by being net sellers. However, we find evidence for this behaviour reversing in times of stress for some investors. During the 2013 ‘taper tantrum’, asset managers were net sellers of corporate bonds in response to a sharp rise in yields, potentially amplifying price changes. At the same time, dealer banks were net buyers. Finally, we provide evidence that insurers, hedge funds and asset managers tilt their portfolios towards higher risk bonds, consistent with ‘reaching for yield’ behaviour.     

A Review of Longitudinal Research in the Product Innovation Field,with Discussion of Utility and Conduct of Sequence Analysis

This paper examines how longitudinality is investigated in innovation research. A review of longitudinal methods in innovation articles, published between 2000 and 2011, is undertaken. Our findings show that longitudinal approaches to data collection are gaining some credence, in line with increased criticism of the overuse of positivist methods to study process‐based phenomena. However, results demonstrate a dearth of systematic longitudinal analytical methods employed in product innovation research. Static analytical methods are prominent. These inevitably lead to static presentation of results, and this is borne out in our findings. Second, the paper discusses the conduct and utility of a specific technique for product innovation research: sequence analysis. By drawing on two studies, which apply sequence analysis in product innovation research, sequence analysis is shown to be a useful technique to achieve rigor in analyzing longitudinal data. The paper concludes by discussing how such systematic methods for analyzing longitudinality in the innovation field demand greater usage and exploration.     

Perceptions and Worry about Hazards at Work: Unions, Contract Maintenance, and Job Control in the U.S. Petrochemical Industry

Union statements and journalist accounts have tied workers' fears of accidents to the increasing use of subcontractors at U.S. petrochemical plants. In this case study of workers at a chemical facility in Louisiana, we explore who perceives and worries about chemical exposures and explosions in the work place and why. Perceptions of chemical exposures were highest among union members, contract workers, and those with low job control, whereas perception of explosions was highest among those reporting being rushed or overworked. Contract workers appear to be more worried about hazards in the industry than direct-hire employees.

Pricing Barrier Options with Time–Dependent Coefficients

We consider the problem of pricing derivative securities which involve a barrier clause. We give general techniques to calculate, or estimate accurately, barrier option prices, using methods for estimating diffusion process boundary hitting times. The solution gives a simple, easy–to–use, method for calculating barrier option prices.     

Le partenariat public-OSBL dans les services sociaux. Le cas espagnol

The article considers the social services supply in the Spanish area of Valencia. The objective is double. First the authors analyse what describes the partnership between public sector and NPO in this area, by using a systemic conception of the social services sector where three main functions can be identified (financing, production and distribution, and regulation). Secondly they search for theoretical arguments explaining this partnership principle. This second section is mainly based on the NPO approach.     

Procedural Fairness, Return to Work, and the Decision to Dispute in Workers' Compensation

This study investigates how injured workers evaluate the fairness of the workers' compensation claims process and how that evaluation affects the decision to formally dispute their claim. Survey and administrative data are used to test a model where individuals are hypothesized to base their overall impression of the fairness of the process based on dimensions of procedural justice criteria. They are then hypothesized to decide whether to formally dispute the claim based on a combination of procedural fairness concerns and whether or not they returned to work with the same employer. The implications of the results for structuring the workers' compensation claims process are then discussed.
