Do Economists Have a Fatherland? How Global and National Efficiency Considerations Influence Economists’ Policy Judgements

This study evaluates whether economists support economic policies such as free trade because they deem them to be good for their home country or because they increase global welfare. In a telephone survey, 100 German economists were asked to judge different policy proposals dealing with immigration, military exports and climate policy. Our results show that the acceptance of the policy proposals is strongly influenced by national efficiency judgements. In contrast, global efficiency judgements exert no significant positive effect on policy proposal acceptance. These effects even hold for economists who self‐reported a global perspective in the assessment of the policy proposals. These judgements might be based on the potentially erroneous assumption that their policy judgements, taken from a national perspective, are consistent with global interests.     

IS THERE A CURSE OF RELOCATION? ANALYSING THE CAUSAL LINK BETWEEN OFFSHORING AND THE INNOVATION PERFORMANCE OF (SMALL) FIRMS

We analyse the empirical link between offshoring activities and different dimensions of innovation performance at the firm‐level. In order to identify causal effects running from offshoring to innovation, we use a quasi‐experimental comparison group approach by means of (conditional) difference‐in‐difference estimations applied to German establishment‐level data for firms that conducted offshoring activities in the period 2007–13. We find that the international relocation of business functions has a negative impact on the firms’ propensity to be innovative in terms of product and process innovations as well as product improvements. While for larger firms the reduction in process innovations is most striking, potentially due to a lack of resources, stagnation in expertise and a reduction in intra‐organizational learning‐by‐doing associated with the relocation of some business activities, for small and medium‐sized enterprises we particularly observe a reduction in product innovations after the offshoring activity has taken place. When interpreting this ‘pessimistic’ picture on the link between offshoring and the innovation performance of firms, the reader should note that our findings for German establishments have to be assessed through the lens of a global economy in economic recession after 2008, which may have intensified the negative impact of offshoring on the firms’ innovation performance.     

Relational effects of relative performance information: The role of professional identity

Prior accounting studies on relative performance information (RPI) have mainly considered the effects of RPI on employees’ performance. This study extends this stream of research by investigating relational effects of RPI that capture RPI recipients’ attitudes towards RPI provision. Specifically, we examine the conditions under which RPI has a positive influence on perceived organizational support (POS). This is important because research on organizational behaviour has demonstrated that POS is an antecedent of desirable job-related attitudes such as organizational commitment, job involvement, and extra-role performance. The results of a dyadic survey in a hospital setting suggest that the effect of RPI on POS is conditional not only on the perceived usefulness of information and relative performance but also on the professional identification of RPI recipients. Our findings indicate that RPI provision is especially suitable for employees who possess a stronger social identification with their peer groups. Our study adds a relational perspective to the hitherto mostly informational and motivational focus in studying social comparison mechanisms linked to RPI systems.     

A customer’s utility measure based on the reliability of multi-state systems

The main focus of this paper is on the development of utility measures for dynamic multi-state systems that have M + 1 discrete states of working efficiency. To develop the utility measures for multi-state systems, we assume that the degradation of the multi-state systems follows a non-homogeneous semi-Markov process together with a backward recurrence time process and that the system can directly degrade into any lower state. The measure considers the immediate utility derived from the state of the system occupancy and the utility due to the system survival expectations derived from its reliability. Moreover, in order to measure the customer’s cumulative utility, the discounted non-homogeneous continuous time semi-Markov process with rewards is implemented. In such a way, the higher order moments of the reward process can be evaluated and then, in particular, the expectation and the standard deviation of the consumer’s accumulated discounted utility. These statistic indices are useful both to the industry in order to compare different system designs offered by the market and to the market itself, in order to know the customer’s utility deriving from the goods she/he consumes. Finally, a numerical example shows the possibility of implementing the model in real-life problems.     

Investition in die Zukunft? Zur Entwicklung des deutschen Auslandsvermögens

Germany’s substantial current account surpluses are an ongoing subject of debate, both at the domestic and the European/ global level. Advocates of high surpluses emphasise the need to accumulate foreign wealth in order to finance future investment and consumption expenditures of an ageing population. This contribution gauges the profitability of Germany’s foreign wealth. It identifies large valuation losses to the tune of half a trillion euros in recent years as well as a persistently adverse trend in previous decades. This unfavourable development as well as historically low refinancing costs point to the comparatively greater benefits of a domestic investment offensive aiming to equip Germany for central long-term challenges.     

Equipping immigrants: migration flows and capital movements in small open economies

This paper explores the extent to which migration-related capital flows can explain the variation in investment rates and current and capital account imbalances in OECD countries. We begin with a general equilibrium model of a small open economy in which migration is exogenous. Migrants must be equipped with capital, and the resulting demands for capital will generate cross-border flows of capital. Next, we move to an empirical exercise in which we allow both capital and labor flows to be endogenous. We test this model using data from a panel of OECD countries. We conclude that migration flows do in fact generate substantial matching capital flows. We calculate that increased migration may have accounted for as much as one-fifth of the increase in the US current account deficit since 1960.     

Does market competitiveness significantly affect public intervention in agricultural insurance: the case in Italy

Analyses of agricultural insurance failures often assume the existence of competitive supply, tracing the reasons for high insurance cost and limited farmer participation to informational problems, and suggesting the need for premium subsidization in order to increase participation. However, in countries such as Spain and Italy, where agricultural insurance is most highly subsidized, it could be that supply is not fully competitive. In this article, we explore the incidence of public subsidies to agricultural insurance premia when supply is noncompetitive. Through the use of a simple empirical model of an insurance market, it is shown that, while in the case of a competitive supply, subsidies to insurance would benefit farmers, a monopolistic supply would capture most of the subsidy, thus eliminating the potential incentive towards wider participation by farmers. The model is applied to a panel of Italian farms for different levels of risk aversion to demonstrate the limited effect that a subsidy to a hypothetical all risk yield insurance would have on farmer participation in the case of monopolistic supply.     

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.     

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.
