Numerical solution of dynamic equilibrium models under Poisson uncertainty

We propose a simple and powerful numerical algorithm to compute the transition process in continuous-time dynamic equilibrium models with rare events. In this paper we transform the dynamic system of stochastic differential equations into a system of functional differential equations of the retarded type. We apply the Waveform Relaxation algorithm, i.e., we provide a guess of the policy function and solve the resulting system of (deterministic) ordinary differential equations by standard techniques. For parametric restrictions, analytical solutions to the stochastic growth model and a novel solution to Lucas' endogenous growth model under Poisson uncertainty are used to compute the exact numerical error. We show how (potential) catastrophic events such as rare natural disasters substantially affect the economic decisions of households.

The migration response to local labour market shocks: Evidence from EU regions during the global economic crisis

The global economic crisis has strongly affected Europe's economic geography. This study investigates the role of local labour market disparities in determining regional net in‐migration rates. While only a weak link is detected in the precrisis period, the local labour market context of migration grows significantly stronger during the crisis. Decompositions of the estimation results show that changes in migration rates are firstly a result of widened disparities across European regions throughout the crisis. However, also behavioural adjustment processes occur, e.g. an orientation of migrants towards urban areas and away from regions with persistently high long‐run unemployment rates.     

Sustainability Management within Supply Chains – A Resource Dependence View

Proceeding from three basic concepts of resource dependence theory – organizational effectiveness, interdependence and external control – we conducted a multiple‐case study to investigate factors that facilitate and hinder sustainability management within supply chains. Our empirical observations highlight that focal firms do not necessarily transfer their own corporate sustainability agendas into control mechanisms for managing the sustainability of their suppliers. Based on this insight, we develop a new theory that explains how intra‐ and interorganizational sustainability management is affected by a firm's business case for promoting sustainability, control mechanisms, trade‐offs, trust and market liberalization. The theory offers new insights into drivers and barriers for effective interorganizational sustainability management, whereas previous theories could not fully explain the reasons for diverging sustainability management practices in supply chains.

The macroeconomic consequences of migration diversion: Evidence for Germany and the UK

This paper examines the macroeconomic consequences of the diversion of migration flows away from Germany towards the UK in the course of the EU's Eastern Enlargement. The EU has agreed transitional periods for the free movement of workers with the new member states from Central and Eastern Europe. The selective application of migration restrictions during the transitional periods has resulted in a reversal of the pre-enlargement allocation of migration flows from the new member states across the EU. Based on a forecast of the migration potential under the conditions of free movement and of the transitional arrangements, we employ a CGE model with imperfect labour markets to analyse the macroeconomic effects of this diversion process. We find that EU Eastern enlargement has increased in the GDP per capita in the UK substantially, but that the diversion of migration flows towards the UK has reduced wage gains and the decline in unemployment there. The effects of the EU Eastern enlargement are less favourable for Germany, but the diversion of migration flows has protected workers there against a detrimental impact on wages and unemployment.     

A Personality‐Competence Model of Opinion Leadership

Opinion leaders constitute a central consumer segment for targeted marketing strategies. By separating opinion leadership into a generalized and domain‐specific component, this study examines the psychological profile of N = 417 consumers from Germany and incorporates opinion leadership into a hierarchical framework of human personality. Results emphasize two major sources of domain‐specific opinion leadership (DSOL): personality in the form of a general, domain‐independent influencer trait and competencies in terms of product‐specific knowledge. Moreover, the study highlights a number of traits including the Big Five of personality, typical intellectual engagement, and general self‐efficacy that form a distinct personality profile of DSOL. The effects of these personality traits on DSOL are partially mediated by generalized opinion leadership and objective knowledge.     

Industry Specific Sustainability Benchmarks: An ECSF Pilot Bridging Corporate Sustainability with Social Responsible Investments

This paper investigates the state of the art with respect to sustainability reporting, its linkages with the corporations, internal measurement and monitoring systems and their combined impact on the quality of contemporary sustainability benchmarks, developed by SRI analysts and so-called rating and screening agencies. This research originated from the EU-funded research initiative to create a new generation management framework for corporate sustainability and responsibility (CS-R). The aim of it is to develop a coherent set of assessment –, measurement – and monitoring tools. The sustainability benchmark tool should align the interests of corporations implementing CS-R and various organizations supporting SRI, such as fund managers, analysts and screening agencies. This paper show the essentials features of an actual sustainability benchmark which is currently under construction. This approach will have significance impact on the further development of SRI and CS-R practices, as well as support the development of sustainability reporting standards.     

Organizational public value and employee life satisfaction: the mediating roles of work engagement and organizational citizenship behavior

Abstract

Building on Meynhardt’s public value concept, which has been developed to make transparent an organization’s contributions to the common good, we investigate the influence of organizational common good practices in the perceptions of employees (measured as public value) on employees’ work attitudes and life satisfaction. The proposed model is tested on a sample of 1045 Swiss employees taken from the 2015 Swiss Public Value Atlas data-set. Study findings reveal that organizational public value is positively related to employee life satisfaction, and that this relationship is partially mediated by work engagement and organizational citizenship behavior. Further, we show that employee common good orientations strengthen the positive impact of organizational public value on employee work engagement and organizational citizenship behavior. Results also provide evidence that the indirect effects of organizational public value on employee life satisfaction via work engagement and organizational citizenship behavior are stronger at higher employee common good orientation levels.     

Evaluating GARCH models

In this paper, a unified framework for testing the adequacy of an estimated GARCH model is presented. Parametric Lagrange multiplier (LM) or LM type tests of no ARCH in standardized errors, linearity, and parameter constancy are proposed. The asymptotic null distributions of the tests are standard, which makes application easy. Versions of the tests that are robust against nonnormal errors are provided. The finite sample properties of the test statistics are investigated by simulation. The robust tests prove superior to the nonrobust ones when the errors are nonnormal. They also compare favourably in terms of power with misspecification tests previously proposed in the literature.
