Does European development have Roman roots? Evidence from the German Limes

This paper contributes to the understanding of the long-run consequences of Roman rule on economic development. In ancient times, the area of contemporary Germany was divided into a Roman and a non-Roman part. The study uses this division to test whether the formerly Roman part of Germany are more developed than the non-Roman part. This is done using the Limes Germanicus wall as geographical discontinuity in a regression discontinuity design framework. The results indicate that economic development—as measured by luminosity—is indeed significantly and robustly larger in the formerly Roman part of Germany. The study identifies the persistence of the Roman road network until the present as an important factor causing this developmental advantage of the formerly Roman part of Germany both by fostering city growth and by allowing for a denser road network.     

Public service motivation and public sector employment preference: Comparing Italian and British students

ABSTRACT

Previous research has suggested that an individual’s public service motivation (PSM) is positively linked to a preference for public sector employment. The authors explore this link using a sample of British and Italian undergraduate students. They found a positive relationship between PSM and public sector job preferences among Italian students but not with the British students. The UK has implemented more NPM-style reforms than Italy and this could be impacting on public sector recruitment. Implications for recruitment and retention the public sector are discussed.     

WHAT DETERMINES THE ELASTICITY OF SUBSTITUTION BETWEEN CAPITAL AND LABOR? A LITERATURE REVIEW

This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. We start by presenting four concise observations that summarize the empirical literature on the estimation of . Motivated by these observations, the main part of this survey then focuses on potential determinants of capital–labor substitution. We first review several approaches to the microfoundation of production functions where the elasticity of substitution (EOS) is treated as a purely technological parameter. Second, we outline the construction of an aggregate elasticity of substitution (AES) in a multi-sectoral framework and investigate its dependence on underlying intra- and inter-sectoral substitution. Third, we discuss the influence of the institutional framework on the extent of factor substitution. Overall, this survey highlights that the effective elasticity of substitution (EES), which is typically estimated in empirical studies, is generally not an immutable deep parameter but depends on a multitude of technological, non-technological, and institutional determinants. Based on these insights, the final section identifies a number of potential empirical and theoretical avenues for future research.     

Price Discrimination in Input Markets: Downstream Entry and Efficiency

The extant theory on price discrimination in input markets takes the structure of the downstream industry as exogenously given. This paper endogenizes the structure of the downstream industry and examines the effects of permitting third‐degree price discrimination on market structure and welfare. We identify situations where permitting price discrimination leads to either higher or lower wholesale prices for all downstream firms. These findings are driven by upstream profits being discontinuous due to costly entry. Moreover, permitting price discrimination fosters entry which often improves welfare. Nevertheless, entry can also reduce welfare because it may lead to a severe inefficiency in production.     

Optimization of Thermal Energy Storage Systems in Distributed Generation Systems

The distributed generation as well as the combined production of electrical energy and heat for domestic use in order to increase the energy efficiency becomes more important and both technically and financially feasible. However, feasibility and efficiency can be significantly increased by decoupling the production of heat or power or the referring demand in order to operate the production units in the most efficient way. Thermal storage systems connected to combined heat and power units offer the opportunity of such a decoupling of production and demand for heat in domestic or industrial use. In this article, based on an analysis of different thermal storage technologies, a model is introduced for optimal operation of thermal storage connected to combined heat and power units in terms of the generation costs or contribution margin as extension of an energy generation planning and trading optimization method. Moreover, the application, coordinated operation and participation in spot markets of such plant-storage-combinations are evaluated.     

Going offshore or better staying in? Spatial relocation strategies and their impact on firm innovativeness

We analyse the short- to mid-run effects of spatial relocation strategies on firm innovativeness and productivity growth. Using conditional difference-in-difference estimation with multiple treatments, we find for a sample of German firms in 1999–2013 that offshoring has a statistically significant negative impact on the firms’ innovation activity and productivity growth vis-à-vis nonrelocating comparison firms. In contrast, we find a positive link between domestic relocation activities and the firms’ propensity to introduce a product innovation. Firms should thus carefully account for potentially distorting performance effects when deciding about the spatial scale of relocation strategies in the short to mid-run.     

Satisfied with red tape? Leadership,civic duty,and career intention in the military

We examine how the coerciveness of HR procedures and leadership behaviours affect job satisfaction (JS) and career intention (CI), and how civic duty (CD) mediates these relationships. Within the framework of the human resource management performance chain, we draw on leadership and motivational theories and test the proposed relations in a structural equation model with data from a survey of the Federal Armed Forces Germany (n = 1,331). The findings show that the behaviour of supervisors, rather than red tape, influences JS and CI. The results extend our understanding of the interplay between leadership behaviours and followership attitudes under high degrees of organizational coercion.     

The labour market effects of offshoring of small and medium-sized firms: micro-level evidence for Germany

Small and medium-sized enterprises (SMEs) are the economic powerhouse of many OECD countries (perhaps most prominently so in Germany). Yet, the labour market dynamics caused by the internationalization of their production activities are largely unexplored. We use survey-based micro-level data for Germany to explore the employment effects of offshoring of SMEs, relying on propensity score matching and difference-in-difference analysis. We find evidence for a downsizing effect in the immediate aftermath of offshoring whereas, initially, job creation is not spurred. In the medium run, we find evidence for a slowing down of employment dynamics of offshoring firms (that tend to belong to the better performing SMEs in Germany) relative to non-offshoring firms. Even though our results do not point to a net employment loss in the medium run, our evidence suggests that offshoring may lead to less jobs being created. This conclusion cannot be confirmed for large companies.
