This paper discusses the relationship between stock market liquidity and corporate governance. Both concepts are widely investigated from different angles in the literature. It is generally agreed that they are related so that better corporate governance implies higher liquidity for shares of...

This paper presents the most extensive analysis of liquidity in the German equity market so far. We examine the evolution of liquidity over time, the determinants of liquidity, and commonality across liquidity measures and countries. We make use of a new publicly available dataset, the Market...

We present new evidence on the structure of euro area securities markets using a multilayer network approach. Layers are broken down by key instruments and maturities as well as the secured nature of the transaction. This paper utilizes a unique dataset of banking sector crossholdings of...

We develop a new methodology to estimate the impact of a financial transaction tax (FTT) on informational efficiency, liquidity and volatility. In our sequential trading model there are price elastic noise traders and traders with private information of heterogeneous quality. We estimate the...

The first paper is co-authored with Sylvain Delalay. We examine the impact of competition between ETFs on measures of market quality of the funds. The surge in new ETF creation has for consequence that groups of competing ETFs are increasingly crowded, and investors can choose from a multitude...

Both the scientific community and the popular press have paid much attention to the speed of the Securities Information Processor-the data feed consolidating all trades and quotes across the US stock market. Rather than the speed of the Securities Information Processor (SIP), we focus here on...

This article shows how the recent money market disruptions with elevated counterparty risks and uncertainty about the fundamental value of liquidity influenced the trading behaviour of a key dealer in the Euro money market. The complete trading record in the unsecured segment of the money market...

We document a sizable OTC discount in the interdealer market for German sovereign bonds where exchange and over-the-counter trading coexist: the vast majority of OTC prices are favorable with respect to exchange quotes. This is a challenge for theories of OTC markets centered around search...

This paper proposes a generalization of the class of realized semivariance and semicovariance measures introduced by Barndorff-Nielsen, Kinnebrock and Shephard (2010) and Bollerslev, Li, Patton and Quaedvlieg (2020a) to allow for a finer decomposition of realized (co)variances. The new "realized...

Tests of excessive volatility along the lines of Shiller (1981) and Leroy and Porter (1981) count among the most convincing pieces of evidence against the validity of the time-honored efficient market hypothesis. Recently, using Shiller s distinction between ex-ante rational (fundamental) price...

This thesis contains three papers. Each paper addresses a distinct research question and is implemented on a separate dataset. The first paper concludes that daytime auctions, together with market opening and closing intervals, contribute to the periodicity of the cross-section of stock returns....

The studies concerning commonality in liquidity on emerging markets in Central and Eastern Europe are scarce and, in particular, they do not utilize the Principal Component Analysis (PCA) to identify latent factors in liquidity. Therefore, the main aim of this research is to assess commonality...

We document a sizable OTC discount in the interdealer market for German sovereign bonds where exchange and over-the-counter trading coexist: the vast majority of OTC prices are favorable with respect to exchange quotes. This is a challenge for theories of OTC markets centered around search...

This study is the first attempt to empirically analyse stock market manipulation on the Nigerian Stock Exchange and its consequences on economic performance. The empirical investigation employs a broad data set of 186 actual manipulation cases indicted by the Nigerian Security and Exchange...

Evaluating more than 317,000 discount certificates in the German secondary market, we find that premiums and spreads are endogenous and negatively related but depend on different key determinants. The fundamental determinants of the premiums are mainly profit‐related, that is, dividends of the...

This paper considers the growth of dark pools: trading venues for equities without pre-trade transparency. It first documents the emergence and expansion of dark pools in European equity markets in the context of regulatory changes and increased high-frequency trading (HFT). It finds that the...

This paper presents the most extensive analysis of liquidity in the German equity market so far. We examine the evolution of liquidity over time, the determinants of liquidity, and commonality across liquidity measures and countries. We make use of a new publicly available dataset, the Market...

We study price dispersion and venue choice in the interdealer market for German sovereign bonds, where an exchange and over-the-counter segments coexist. We show that 85% of OTC traded prices are favorable with respect to exchange quotes, indicating the prevalence of an OTC discount. This...

This paper is the first to analyze the joint determinants of premiums and spreads in structured financial products, while also focusing on issuers' hedging costs. We evaluate more than 396,000 single stock discount certificates on an intraday basis in the German secondary market. We find that...

We examine the impact of dynamic hedging demand of German option and discount certificate markets on the autocorrelation of German stock price changes. We theoretically model the demand of liquidity providers in the discount certificate market, a structured financial product with a concave...

Recent event study literature has highlighted abnormal stock returns, particularly in short event windows. A common explanation is the cross-correlation of stock returns that are often enhanced during periods of sharp market movements. This suggests the misspecification of the underlying factor...

The majority of electronic markets worldwide employ limit order books, and the recently emerging exchanges for cryptocurrencies pose no exception. With this work, we empirically analyze whether commonly observed empirical properties from established limit order exchanges transfer to the...

This article presents an overview of research on the Microstructure of Foreign Exchange Markets. We begin by summarizing the institutional features of FX trading and describe how they have evolved since the 1980s. We then explain how these features are represented in microstructure models of FX...

Dealers, who strategically supply liquidity to traders, are subject to both liquidity and adverse selection costs. While liquidity costs can be mitigated through inter-dealer trading, individual dealers' private motives to acquire information compromise inter-dealer market liquidity. Post-trade...
