Correlation Risk and International Portfolio Choice (2019)
Branger, Nicole ; Muck, Matthias ; Weisheit, Stefan
Variance‐covariance risk of the exchange rate is highly relevant for international investors. This paper addresses optimal asset allocation with stochastic variances and covariances in a Wishart Affine Stochastic Correlation (WASC) model in incomplete and complete markets. We show that the (hedging) demand for exchange rate variance‐covariance risk can differ significantly between international investors. Local correlations with the exchange rate can affect the utilities of international investors differently while the impact of correlations between stocks can be symmetric. Depending on the current local exchange rate correlations domestic investors can benefit more or less than foreign investors from international trading.

Immigration-related Speechmaking in a Party-constrained Parliament: Evidence from the ‘Refugee Crisis’ of the 18th German Bundestag (2013–2017) (2019)
Geese, Lucas
The 18th Bundestag term was marked by a high salience of the refugee and asylum issue dominating the political agenda. Taking this context as a case study, this paper asks which factors make legislators talk about immigration on the parliamentary floor. Three different literatures provide different answers to this question. A first literature highlights that immigrant-origin legislators with a visible background may have intrinsic motives to talk about immigration. A second literature raises attention to legislators’ personal vote-seeking incentives to talk about immigration when the issue is electorally decisive. Contrary to these first two literatures, a third literature posits that legislative debates do not provide legislators the leeway to follow individual motives on the parliamentary floor, but that parliamentary party groups (PPGs) control access to the parliamentary floor and thus follow own strategies when allocating floor time to speak about the immigration issue. To examine this puzzle of competing expectations, a corpus of more than 10,000 speeches is leveraged, utilising a structural topic model, a novel method of quantitative text analysis. Results suggest that legislators’ speech attention to the refugee and asylum issue in the 18th Bundestag was mainly shaped by PPG specific factors rather than by their individual motives.
MPs’ principals and the substantive representation of disadvantaged immigrant groups (2019)
Geese, Lucas ; Schwemmer, Carsten
This article provides an alternative understanding of the substantive representation of immigrant-origin citizens compared to previous work in the ‘politics of presence’ tradition. Rather than assuming that the representational activities of members of parliaments (MPs) are underpinned by intrinsic motivations, it highlights extrinsic motives. Drawing on principal–agent theory, the article conceptualises MPs as delegates who are to act on behalf of their main principals, constituents and party bodies. This approach permits the rigorous analysis of the impact of electoral rules, candidate selection methods and legislative organisation on substantive representation. Based on an analysis of more than 20,000 written parliamentary questions tabled in the 17th German Bundestag (2009–2013), empirical findings suggest that electoral rules do not influence the relationship between MPs and their principals in relation to the substantive representation of disadvantaged immigrant groups; however, results indicate that candidate selection methods as well as powerful parliamentary party group leaderships do.
Proactive career behaviors and subjective career success: The moderating role of national culture. (2019)
Smale, Adam ; Bagdadli, Silvia ; Cotton, Rick ; Dello Russo, Silvia ; Dickmann, Michael ; Dysvik, Anders ; Gianecchini, Martina ; Kaše, Robert ; Lazarova, Mila ; Reichel, Astrid ; Rozo, Paula ; Verbruggen, Marijke ; Andresen, Maike
Although career proactivity has positive consequences for an individual's career success, studies mostly examine objective measures of success within single countries. This raises important questions about whether proactivity is equally beneficial for different aspects of subjective career success, and the extent to which these benefits extend across cultures. Drawing on Social Information Processing theory, we examined the relationship between proactive career behaviors and two aspects of subjective career success—financial success and work‐life balance—and the moderating role of national culture. We tested our hypotheses using multilevel analyses on a large‐scale sample of 11,892 employees from 22 countries covering nine of GLOBE's 10 cultural clusters. Although we found that proactive career behaviors were positively related to subjective financial success, this relationship was not significant for work‐life balance. Furthermore, career proactivity was relatively more important for subjective financial success in cultures with high in‐group collectivism, high power distance, and low uncertainty avoidance. For work‐life balance, career proactivity was relatively more important in cultures characterized by high in‐group collectivism and humane orientation. Our findings underline the need to treat subjective career success as a multidimensional construct and highlight the complex role of national culture in shaping the outcomes of career proactivity.
