A unified approach to systemic risk measures via acceptance sets

We specify a general methodological framework for systemic risk measures via multidimensional acceptance sets and aggregation functions. Existing systemic risk measures can usually be interpreted as the minimal amount of cash needed to secure the system after aggregating individual risks. In contrast, our approach also includes systemic risk measures that can be interpreted as the minimal amount of cash that secures the aggregated system by allocating capital to the single institutions before aggregating the individual risks. An important feature of our approach is the possibility of allocating cash according to the future state of the system (scenario‐dependent allocation). We also provide conditions that ensure monotonicity, convexity, or quasi‐convexity of our systemic risk measures.     

Currency devaluations and beggar-my-neighbour penalties: evidence from the 1930s

The currency devaluations of the 1930s facilitated a faster recovery from the Great Depression in the countries depreciating, but their unilateral manner provoked retaliatory and discriminatory commercial policies abroad. This article explores the importance of the retaliatory motive in the imposition of trade barriers by gold bloc countries during the 1930s and its effects on trade. Relying on new and existing datasets on the introduction of quotas, tariffs, and bilateral trade costs, the quantification of the discriminatory response suggests that these countries imposed significant beggar-my-neighbour penalties. The penalties reduced trade to a similar degree that modern regional trade agreements foster trade. Furthermore, the analysis of contemporary newspapers reveals that the devaluations of the early 1930s triggered an Anglo-French trade conflict marked by tit-for-tat protectionist policies. With regards to global trade, the unilateral currency depreciations came at a high price in political and economic terms. These costs must have necessarily reduced their benefit to the world as a whole.

The influence of ownership structure and board strategic involvement on international sales: The moderating effect of family involvement

This paper contributes to the family business and the international business literature by analysing whether and to what extent different compositions of the ownership structure and degrees of board strategic involvement impact on the level of international sales of family and non-family businesses. Our main hypotheses are tested on a sample of 342 Norwegian firms via regression analysis. The results from this study show the existence, in both in family and non-family businesses, of a positive and significant relationship between foreign investors’ ownership and the level of international sales. Furthermore, the relationship between CEO ownership impacts negatively on international sales in both family and non-family businesses. While board strategic involvement contributes positively to international sales in non-family businesses it becomes not significant when we only look at family businesses. Implications for theory and practice and future research directions are discussed.     

Wirkungen einer Beseitigung des „Mittelstandsbauchs“ im Einkommensteuertarif

German income tax revenue is rising continuously, and at a faster rate than overall revenue. This is why tax reductions are increasingly called for. One option is to abolish or at least level the so-called “middle class bulge”. This paper analyses how different tax reform variants affect revenue and the distribution of the tax burden across taxpayers.
