Cryptocurrencies provide a unique opportunity to identify how derivatives impact spot markets. They are fully fungible, trade across multiple spot exchanges at different prices, and futures contracts were selectively introduced on bitcoin (BTC) exchange rates against the USD in December 2017. Following the futures introduction, we find a significantly greater increase in cross-exchange price synchronicity for BTC--USD relative to other exchange rate pairs, as demonstrated by an increase in price correlations and a reduction in arbitrage opportunities and volatility. We also find support for an increase in price efficiency, market quality, and liquidity. The evidence suggests that futures contracts allowed investors to circumvent trading frictions associated with short sale constraints, arbitrage risk associated with block confirmation time, and market segmentation. Overall, our analysis supports the view that the introduction of BTC--USD futures was beneficial to the bitcoin spot market by making the underlying prices more informative.
Dieser Beitrag ist ein Besprechungsaufsatz zu Beatrice Brunhöbers 2010 erschienener Dissertation Die Erfindung „demokratischer Repräsentation“ in den Federalist Papers (Mohr Siebeck, Tübingen: Grundlagen der Rechtswissenschaft, Bd. 14), in der Brunhöber die innovative – und auch die Verfassungsentwicklung andernorts prägende – Kraft der Verbindung von Demokratie, politischer Repräsentation und Föderalismusidee durch die amerikanischen Verfassungsväter herausarbeitet. Auf der Basis von Brunhöbers Untersuchung geht es insbesondere darum, wie sich das von Hamilton, Madison und Jay entworfene ‚alte‘ Konzept zur Gestaltung eines starken Gemeinwesens (eingeschlossen das vertrauensbildende Prinzip der Gewaltenteilung) für einen integrativen Umgang mit den ‚modernen‘ Gegebenheiten pluralistischer Gesellschaften nutzbar machen läßt, im Blick die Gesamtheit (und Vielfalt) des Staatsvolkes als Geltungsfundament legitimer Herrschaft. Im Hintergrund steht die Frage nach Möglichkeiten zur Nutzbarmachung historischer Vergewisserungen für heutige Debatten überhaupt.
This paper aims at an improved understanding of the relationship between monetary policy and racial inequality. We investigate the distributional effects of monetary policy in a unified framework, linking monetary policy shocks both to earnings and wealth differentials between black and white households. Specifically, we show that, although a more accommodative monetary policy increases employment of black households more than white households, the overall effects are small. At the same time, an accommodative monetary policy shock exacerbates the wealth difference between black and white households, because black households own less financial assets that appreciate in value. Over multi-year time horizons, the employment effects are substantially smaller than the countervailing portfolio effects. We conclude that there is little reason to think that accommodative monetary policy plays a significant role in reducing racial inequities in the way often discussed. On the contrary, it may well accentuate inequalities for extended periods.
Gerichte können einem Täter, der wegen Straftaten verurteilt wurde, die auf seinen Suchtmittelkonsum zurückgehen, die Weisung erteilen, jeglichen Alkoholkonsum zu unterlassen und sich entsprechenden Kontrollen zu unterziehen. Die Kontrolle der Weisungen stößt jedoch bislang an enge Grenzen. Bisher kann deren Einhaltung nur stichprobenartig überprüft werden. Einen neuen Ansatz bietet eine kontinuierliche (transdermale) Alkoholüberwachung mittels eines am Fußgelenk getragenen Messgerätes. Ein Blick in die USA zeigt, dass die elektronische Überwachung des Alkoholkonsums erprobt wurde und sich durchgesetzt hat. Der Beitrag untersucht die Bedeutung einer kontinuierlichen transdermalen Alkoholüberwachung für die Abstinenzkontrolle und inwieweit diese Methode im deutschen System verankert werden kann.
Using loan-level data from Germany, we investigate how the introduction of model-based capital regulation affected banks’ ability to absorb shocks. The objective of this regulation was to enhance financial stability by making capital requirements responsive to asset risk. Our evidence suggests that banks ‘optimized’ model-based regulation to lower their capital requirements. Banks systematically underreported risk, with under reporting being more pronounced for banks with higher gains from it. Moreover, large banks benefitted from the regulation at the expense of smaller banks. Overall, our results suggest that sophisticated rules may have undesired effects if strategic misbehavior is difficult to detect.
Stability maintenance at the grassroots: China’s weiwen apparatus as a form of conflict resolution
(2013)
This working paper explores the history and potential of “stability maintenance” (weiwen) as a form of conflict resolution in China. Its emphasis on conflict resolution is novel. Previous examinations of the weiwen apparatus have concentrated on its political function, namely to manage resistance within society and maintain the authority of the party-state. This avenue of investigation has proved fruitful as a means of characterising the political motivation and the higher-level strategies involved in stability maintenance. Nonetheless, there remain significant conceptual and empirical gaps relating to how stability maintenance offices and processes actually function, particularly out of larger cities and at local levels. The research described in this paper aims to consider the effectiveness of stability maintenance as a part of the “market” for conflict resolution in local China, and to test the hypothesis that conflict resolution as facilitated by weiwen is the most pragmatic and effective means of actually resolving conflicts in the current Chinese political context, notwithstanding the closeness of the stability maintenance discourse to state authority and its relative distance from rule of law-based methods of dispute resolution...
Using granular supervisory data from Germany, we investigate the impact of unconventional monetary policies via central banks’ purchase of corporate bonds. While this policy results in a loosening of credit market conditions as intended by policy makers, we document two unintended side effects. First, banks that are more exposed to borrowers benefiting from the bond purchases now lend more to high-risk firms with no access to bond markets. Since more loan write-offs arise from these firms and banks are not compensated for this risk by higher interest rates, we document a drop in bank profitability. Second, the policy impacts the allocation of loans among industries. Affected banks reallocate loans from investment grade firms active on bond markets to mainly real estate firms without investment grade rating. Overall, our findings suggest that central banks’ quantitative easing via the corporate bond markets has the potential to contribute to both banking sector instability and real estate bubbles.
This paper documents that resource reallocation across firms is an important mechanism through which creditor rights affect real outcomes. I exploit the staggered adoption of an international convention that provides globally consistent strong creditor protection for aircraft finance. After this reform, country-level productivity in the aviation sector increases by 12%, driven mostly by across-firm reallocation. Productive airlines borrow more, expand, and adopt new technology at the expense of unproductive ones. Such reallocation is facilitated by (i) easier and quicker asset redeployment; and (ii) the influx of foreign financiers offering innovative financial products to improve credit allocative efficiency. I further document an increase in competition and an improvement in the breadth and the quality of products available to consumers.
