The diminution of the physical stature of the English male population in the eighteenth century

We re-estimate the height of Englishmen using the sample originally collected by Roderick Floud. We merge the samples from the army and the Royal Marines by weighting the observations in order to reflect the proportions of servicemen in the two branches of the military. In addition to truncated regression, we use cubic spline functions in order to estimate the trend in the physical stature of Englishmen. The results indicate that a very rapid decline in height of c. 1.6 cm per decade accompanied the onset of the industrial and demographic revolutions, implying that the nutritional status of the population deteriorated considerably as it throughout the European Continent.     

Delegation and incentives

This article analyzes the relation between authority and incentives. It extends the standard principal‐agent model by a project selection stage in which the principal can either delegate the choice of project to the agent or keep the authority. The agent's subsequent choice of effort depends both on monetary incentives and the selected project. We find that the consideration of effort incentives makes the principal less likely to delegate the authority over projects to the agent. In fact, if the agent is protected by limited liability, delegation is never optimal.     

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.

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.     

Exports and Productivity Growth: First Evidence from a Continuous Treatment Approach

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. However, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are restricted to analysing the relationship between a firm’s export status and the growth of its labour productivity, using the firms’ export status as a binary treatment variable and comparing the performance of exporting and non-exporting firms. In this paper, we apply the newly developed generalised propensity score (GPS) methodology that allows for continuous treatment, that is, different levels of the firms’ export activities. Using the GPS method and a large panel data set for German manufacturing firms, we estimate the relationship between a firm’s export-sales ratio and its labour productivity growth rate. We find that there is a causal effect of firms’ export activities on labour productivity growth. However, exporting improves labour productivity growth only within a sub-interval of the range of firms’ export-sales ratios. JEL no.  F14, F23, L60     

Households’ foreign currency borrowing in Central and Eastern Europe

Foreign currency loans represent an important feature of recent financial developments in CEECs. This might pose a serious challenge for macroeconomic stability. Against this background, we study the determinants of foreign currency loans of households, using data on the behavior of households in nine CEECs. Our results reveal that foreign currency loans are driven by households’ lack of trust in the stability of the local currency and in domestic financial institutions. Moreover, special factors including remittances and expectations of euro adoption play an important role in selected regions. The financial crisis reduced foreign currency borrowing, but there is some indication this effect might be only temporary.     

Quantifying the CO2 Permit Price Sensitivity

Equilibrium models have been widely used in the literature with the aim of showing theoretical properties of emissions trading schemes. This paper applies equilibrium models to empirically study permit prices and to quantify the permit price sensitivity. In particular, we demonstrate that emission trading schemes both with and without banking are inherently prone to price jumps.     

Power learning: racing ahead of your competition

Adhering to accepted practices, not wanting to rock the boat, and squelching dissenting opinions sentence organizations to a repetition of their mistakes. To be successful, organizations must continually learn. Organizations that learn are competitive. They are on the leading edge. They create their own futures instead of being created by their futures. The objective of this article is to present a new approach to learning that greatly enhances the quality of training and educational programs. The key subjects include learning styles, left and right brain processing, and the 4MAT System. In addition, two brief case studies are presented.     

Die Agenda — ein Konstrukt des Rezipienten?

The objective of this study is to integrate schema theory into the agenda-setting model. We examined the influence of cognitive schemas on the perception of political issues presented in the media. We used a multi-method-design to scrutinize 25 young adults’ perception of the television debates between chancellor Schröder and his challenger during the 2002 German election campaign. Before the debates took place, participants were interviewed, using a standardized questionnaire. After having watched the debates in familiar surroundings, participants were asked to reproduce the discussed issues by a non-standardized, open questionnaire. Additionally, the debates were analyzed and the issues discussed were ranked. Results indicate that recipients pay more attention to political issues already clearly anchored in their issue schemas, and remember those issues better than others. Our results underline that a further inclusion of schema theory into the agenda-setting model is necessary to better reconstruct the process of political information processing.
