We explore the connection between money, banks, and aggregate credit. We start with a simple 'real' model without money, where banks make loans repayable in goods and depositors hold claims on the bank payable on demand in goods. Aggregate production may be delayed in the economy. If so, we show...

We study arbitrage opportunities in diverse markets as introduced by R. Fernholz in [Fer99]. By a change of measure technique we are able to generate a variety of diverse markets. The construction is based on an absolutely continuous, but nonequivalent measure change which implies the existence...

This paper studies a dynamic market microstructure model, in which a strategic market maker competes with an informed trader. We include the presence of noise traders and limit order traders in our setup. Our model is a N-period model. We give necessary and sufficient conditions for an...

This paper analyzes banking crises using a quantitative model with equilibrium default for both firms and banks. The main results are: 1) small open economies have larger banking crises than closed or large economies. Constant international rates do not mitigate interbank spreads and amplify...

We present an order flow model framework for limit order driven markets. Different from previous models we explicitly model a reference price process that “sweeps” the limit order book as it fluctuates up and down. Our framework allows us to use any stochastic process to model this reference...

We show the statistical properties of the most important cryptocurrencies, of which Bitcoin is the most prominent example. We characterize their exchange rates versus the US Dollar by fitting parametric distributions to them. It is shown that returns are clearly non-normal, with standard...

Cryptocurrencies became popular with the emergence of Bitcoin and have shown an unprecedented growth over the last few years. As of November 2016, more than 720 cryptocurrencies exist, with Bitcoin still being the most popular one. We provide both a statistical analysis as well as an extreme...

We provide an extreme value analysis of the returns of Bitcoin. A particular focus is on the tail risk characteristics and we will provide an in-depth univariate extreme value analysis. Those properties will be compared to the traditional exchange rates of the G10 currencies versus the US...

This contribution deals with the conflict-of-laws principles governing Financial Instruments, Bonds & Loans, Cheques, Bills of Exchange and Guarantees. It starts with comparative and historic aspects and then goes on to deal with issues regarding the determination of the applicable law. The...

We analyze banking crises and lending of last resort (LOLR) in a quantitative model of financial frictions with bank defaults. LOLR policies generate a tradeoff between financial fragility (due to more highly leveraged banks) and milder crises since the policies are effective once in a crisis....
