The pervasive absence of compensating differentials

We study the relation between individual preferences for job amenities (e.g., type of work, job security) and compensating wage differentials in cross‐section. To this end, we estimate a partial equilibrium job search model on panel data from eight European countries. There are five non‐wage job characteristics and two sources of job‐to‐job mobility: on‐the‐job search and reallocation shocks. We also allow for two types of unobserved heterogeneity. We find strong preferences for amenities, especially job security, yet, these preferences do not translate into significant wage differentials in cross‐section. Counterfactual experiments show that one would need extremely low levels of search frictions for compensating differentials to arise. Lastly, a similar exercise on the distribution of job change outcomes reveals the role of constrained job‐to‐job mobility in the absence of compensating wage differentials.

Zuwendung inbegriffen

Besser leben im Heim - Pflegekr?fte arbeiten oft unter Zeitdruck. Um die Lebensqualit?t von Bewohnern mit erheblich eingeschr?nkter Alltagskompetenz zu verbessern, sieht der Gesetzgeber im Pflege-Weiterentwicklungsgesetz vom 1. Juli 2008 zus?tzliche Betreuungskr?fte vor. Im Rummelsberger Stift St. Lorenz in Nürnberg macht man mit ihnen positive Erfahrungen.     

Co-movements of index options and futures quotes

We report evidence that the co-movements of index options and index futures quotes differ sharply from perfect correlation in periods with option trades. In half-hour intervals with (without) option trades 25% (12%) of call option quote changes have either the opposite sign or are larger in magnitude than the corresponding index futures quote changes. We calibrate a stochastic volatility model that allows for trade and no-trade periods using real data and simulate the joint co-movements of index quotes and option quotes in this model. We show that for trade intervals the observed co-movements differ from the benchmark case established by our simulations approximately three times too often. We provide empirical evidence that market microstructure effects – specifically, stale quotes and aggressive quotes – explain the majority of the deviations from the benchmark. Our findings are relevant for techniques that use estimates of local co-movements as inputs to price or hedge options.

Understanding how HR systems work: the role of HR philosophy and HR processes

Despite the proliferation of studies of HR systems, there are still substantial gaps in our understanding of how such systems actually work. This article, by focusing on the neglected areas of HR philosophy and HR processes in the composition of HR systems, and by using a qualitative, employee‐centred approach in the collection and analysis of data, provides new insights into the working of HR systems. Using data from interviews with 56 knowledge workers employed in the information and communications technology sector in Ireland and the UK, we explore employee‐level reactions to two different types of HR systems. We highlight the various ways in which HR processes interact with HR practices and the different outcomes that may result, and we identify the key role of HR philosophy in HR system operation.
