We investigate the impact of high-frequency trading (HFT) on market quality and investor welfare using a general limit order book model. We find that while the presence of HFT always improves market quality under symmetric information, under asymmetric information this is the case only if...

In this paper, I estimate the effect of mandatory greenhouse gas (GHG) emissions disclosure on corporate value. Using the introduction of mandatory GHG emissions reporting for firms listed on the Main Market of the London Stock Exchange as a source of exogenous variation, I find that firms most...

We integrate bank and bond financing into a two-sector neoclassical growth model to examine the stabilization effect of endogenous bank leverage adjustment. We show that although bank leverage amplifies shocks, the increase of leverage to a decline in bank equity is an automatic stabilizer in...

The regulator plays an active role in the IPO process via its pre-IPO communications with firms, writing 3.8 comment letters per company. To evaluate the regulator's input, we analyze these communications between the SEC and firms using LDA-analysis and KL-divergence. Main topics of SEC concerns...

This is a summary of the main topics and findings from the Swiss Risk and Insurance Forum 2015. That event gathered experts from academia, insurance industry, regulatory bodies, and consulting companies to discuss the past and current developments and necessary next steps for dealing with...

Price impact measures the difference between the best quoted price and the realized price as a function of order size. This paper analyzes how price impact depends on the latency that a market maker is subject to. I propose a tractable model which allows incorporating both order size and latency...

Machine learning techniques make it feasible to calculate claims reserves on individual claims data. This paper illustrates how these techniques can be used by providing an explicit example in individual claims reserving

These notes aim at giving a broad skill set to the actuarial profession in insurance pricing and data science. We start from the classical world of generalized linear models, generalized additive models and credibility theory. These methods form the basis of the deeper statistical understanding....

We study the impact of higher capital requirements on banks' balance sheets and its transmission to the real economy. The 2011 EBA capital exercise is an almost ideal quasi-natural experiment to identify this impact with a difference-in-differences matching estimator. We find that treated banks...

Making use of a structural model that allows for optimal liquidity management, we study the role that repos play in a bank's financing structure. In our model the bank's assets consist of illiquid loans and liquid reserves and are financed by a combination of repos, long–term debt, deposits...
