The paper analyzes the link between the public pension system and the immigration policy. In a pay-as-you-go system, the incentives for immigration vary significantly between individuals at different lifetime periods. In the framework of an overlapping generations model, we show that the median voter's choice in general leads to inefficient levels of immigration. The median voter neglects the effects of the externalities within the pension system on other generations. An immigration policy that is not affected by the median voter's choice but instead is constitutionally determined will avoid welfare losses. The expected lifetime income of each generation can be increased by applying a rule of steady immigration. 相似文献

Germany’s federal states can enforce stricter regulations on genetically modified organisms (GMOs) than does the national government. Empirically, the study analyses two outcomes at the state level: the symbolic accession to the GMO-free network, in which regional units mobilise against the EU’s regulatory approach, and hard GMO policies/regulations. Besides focussing on political parties and environmental interest groups, the article provides various additional theoretical explanations for the variation in outcomes. The research questions are the following: what conditions a state’s accession to the GMO-free network? What conditions a state’s adoption of GMO regulations? To assess these questions, the study employs fuzzy-set qualitative comparative analysis. One finding is that the inclusion of the Green Party in government is not a predominant condition for the adoption of regulations, but ministers affiliated with the Greens are dominant drivers of symbolic policy-making. The study reveals differing regulatory action by CDU/CSU ministers in the western and eastern states, which can be explained by the differing interests of farmers. Other findings reveal that SPD ministers regulated GMOs to much the same extent as CDU/CSU or Green ministers. Environmental interest groups were also found to have positively conditioned symbolic policy-making, having no effect, however, on the adoption of concrete regulations. 相似文献

Questions of how and when managers can motivate the workforce of public organizations are fundamental for scholars and practitioners alike. A dominant assertion is that goal‐oriented leadership strategies, such as transformational leadership, foster public service motivation (PSM). However, existing studies rely on designs that are vulnerable to endogeneity and rarely investigate the scope conditions of the leadership‐PSM relationship. Combining a field experiment with 364 managers and surveys of their 3,470 employees, the authors show that transformational leadership and transactional leadership, when induced experimentally, do not have the claimed positive effect on PSM. In fact, the results indicate that goal‐oriented leadership can have demotivating effects when employee and organizational values are incongruent. Public managers should therefore carefully assess existing levels of value (in)congruence before implementing goal‐oriented leadership strategies, and—in case of value conflicts—seek to align perceptions of the desirable among members of the organization. 相似文献

We outline a comprehensive research program on institutional reforms in European parliaments. Original data show that parliamentary rules in Western European parliaments have been changed frequently and massively during the period from 1945 to 2010 suggesting that actors use institutional reforms as a distinct strategy to pursue their substantive goals. We discuss how institutional instability affects existing theoretical and empirical arguments about institutional effects. Furthermore, we present four ideal‐typical approaches to analyzing rule changes, present new software tools for identifying and coding changes in large text corpora, and demonstrate their usefulness for valid measurement of the overall change between subsequent text versions. 相似文献

Security provision in and by the EU has become an issue of increasing public interest and controversy. There are diverse and growing demands and critiques from different political camps towards the EU while EU institutions, in turn, utilise their security function as a resource for authority construction and self-legitimation. More recently, European security has also become intertwined with contemporary “crises” that turned it into an arena for the negotiation of fundamental conflicts, often revolving around questions of identity and sovereignty. This paper argues that these developments represent a significant change of European security and its politics that existing approaches linking the field to depoliticisation cannot adequately capture. To fill this gap, this paper suggests applying a politicisation perspective that, so far, has focused on the European integration project as such or the “Eurozone crisis” to the purportedly special security field. 相似文献

Despite the proliferation of research on public service motivation (PSM), fundamental questions about its origins continue to evade scholars: Is PSM driven by genetics, socialized through experiences, or both? If PSM is socialized, when does socialization occur? Answering these questions is critical for reconciling the state versus trait debate, and for assessing the validity of practical implications prescribed by PSM studies. Utilizing “nature's own experiment,” we adopt a classical twin design with 1035 twin pairs to identify how genetic heritability, a common environment, or unique environment and experiences can explain variation in PSM. Results show that PSM is heavily influenced by individuals' unique environments and experiences; not by genetics. This lends strong evidence to PSM's uniqueness as a motivational construct as related “other-regarding” concepts show sizeable genetic components. Finally, our results corroborate that PSM is a human resource with dynamic properties organizations can cultivate to enhance productivity in public service workforces. 相似文献
