3. A Short Note on Absorbed Geometric Brownian Motions
abstractOur aim is to give an explicit expression of the cumulative density function of an absorbed stochastic process at terminal time T. This process is the wealth process induced by holding a stock following a geometric Brownian motion and investing this amount in the money market account as soon as the stock hits a lower, time-dependent threshold

4. Kendall's Rank Correlation vs Pearson's Linear Correlation : A Proof Of Greiner's Relation
abstractThe aim of this paper is to give a proof of Greiner's equality which describes the relation between Kendall's rank correlation and the linear correlation according to Pearson in the case of correlated Gaussian random pairs

5. Europäische Optionen im Brigo-Mercurio Hybridmodell (European Options in the Brigo-Mercurio Model)
abstractGerman Abstract: In dem vorliegenden Artikel beweisen wir explizite Formeln (siehe Satz 2.2) für den Preis europäischer Call- und Put-Optionen auf einen Aktienindexprozess, dessen Entwicklung dem Hybridmodell von D. BRIGO und F. MERCURIO (siehe [2]) folgt.Für den Beweis von Satz 2.2 erweitern wir dazu die Formel von MARGRABE (siehe Lemma 2) für Kapitalmarktmodelle, die wie das BRIGO-MERCURIO Hybridmodell eine nicht deterministische Verzinsung aufweisen

6. Hitting Times with Respect to Time-Dependent Barriers
abstractIn this short note, we prove that the distribution function of a hitting time of a Brownian Motion with respect to a differentiable, lower threshold solves a Volterra integral equation of second type. Moreover, we give an explicit expression for the kernel of the integral equation in terms of the boundary function and demonstrate how to find a solution of that equation (i.e. the distribution function) using Banach's Fixed-Point Theorem.As a second step, based on the first result, we find an integral representation of the terminal wealth distribution attached to the following, self-financing strategy: Let S_t be standard Geometric Brownian Motion stopped as soon as S_t hits a lower, time-dependent threshold. Then invest all of S_t in the money market account

7. Commercial Imperialism? Political Influence and Trade During the Cold War
abstractWe exploit the recent declassification of CIA documents and examine whether there is evidence of US power being used to influence countries' decisions regarding international trade. We measure US influence using a newly constructed annual panel of CIA interventions aimed at installing and supporting leaders during the Cold War. Our presumption is that the US had greater influence over foreign leaders that were installed and backed by the CIA. We show that following CIA interventions there was an increase in foreign-country imports from the US, but there was no similar increase in foreign-country exports to the US. Further, the increase in US exports was concentrated in industries in which the US had a comparative disadvantage in producing, not a comparative advantage. This is consistent with US influence being used to create a larger foreign market for American products. Our analysis is able to rule out decreased bilateral trade costs, changing political ideology, and an increased supply of US loans and grants as explanations for the increase in US exports to the intervened country. We provide evidence that the increase in US exports arose through direct purchases of US products by foreign governments

8. Superpower interventions and their consequences for democracy : an empirical inquiry
abstract"Do superpower interventions to install and prop up political leaders in other countries subsequently result in more or less democracy, and does this effect vary depending on whether the intervening superpower is democratic or authoritarian? While democracy may be expected to decline contemporaneously with superpower interference, the effect on democracy after a few years is far from obvious. The absence of reliable information on covert interventions has hitherto served as an obstacle to seriously addressing these questions. The recent declassification of Cold War CIA and KGB documents now makes it possible to systematically address these questions in the Cold War context. We thus develop a new panel dataset of superpower interventions during the Cold War. We find that superpower interventions are followed by significant declines in democracy, and that the substantive effects are large. Perhaps surprisingly, once endogeneity is addressed, US and Soviet interventions have equally detrimental effects on the subsequent level of democracy; both decrease democracy by about 33%. Our findings thus suggest that one should not expect significant differences in the adverse institutional consequences of superpower interventions based on whether the intervening superpower is a democracy or a dictatorship"--National Bureau of Economic Research web site

10. Violence and Cell Phone Communication : Behavior and Prediction in Cote D’Ivoire
abstractWe investigate the relationship between low-level incidents of political violence and communication patterns seven months after the 2012 Ivorian Civil War using network traffic from all of Orange Telecom’s Cote d’Ivoire cell towers and 500,000 randomly sampled cell phone subscribers. We first show that in the days preceding small violent incidents, mobile phone call volumes increase by 10% and the number of cell phones that are active increases by 6%, while the length of average calls decreases by 4%. These unique communication patterns attenuate as the distance from violence increase and strengthen when incidents with no fatalities are excluded. We then use machine learning techniques to explore whether these changes can predict the day and location of violent events. The addition of cell phone data to base models appear to improve our ability to predict violent events at very fine spatial and temporal resolution
