We develop a new likelihood-based approach to sign trades in the absence of quotes. It is equally efficient as existing MCMC methods, but more than 10 times faster. It can deal with the occurrence of multiple trades at the same time, and noisily observed trade times. We apply this method to a...

In their seminal paper French and Roll (1986) postulate that public information affects prices before anyone can trade on it. In contrast, several models assuming heterogeneous investors show that public news releases are directly followed by high trading volume. Empirical evidence on this...

The disclosure requirements for firms issuing equity on German crowdinvestingplatforms are quite lax at the moment. This paper states that this loose requirement policy is not optimal in the presence of competition among platforms. First, a simple three-staged theoretical model is derived to...

On crowdinvesting-platforms, non-publicly traded companies can offer equity to private investors. Currently, platforms like Crowdcube.com in Great Britain or Seedmatch.de in Germany are using a mechanism for the allocation of available shares best described by the phrase first come, first...

A number of recent theoretical studies have explored trading in fragmented markets, e.g. Biais etal. (2000), a phenomenon increasingly witnessed in modern markets. The key assumptiongenerating the results is that there is at least one liquidity demander exploiting access to allmarkets by...

This paper investigates the relationship between annual report disclosure, market liquidity, and capital cost for firms registered on the Deutsche Börse. Disclosure is comprehensively measured using the innovative Artificial Intelligence Measurement of Disclosure (AIMD). Results show that...

This study explores the effect of several personal religion-related variables on social behaviour, using three paradigmatic economic games: the dictator (DG), ultimatum (UG), and trust (TG) games. A large carefully designed sample of a Spanish urban adult population (N=766) is employed. From...

The paper analyses the ownership structure of a large sample of Spanish listed companies. The results are analysed in terms of governance implications under the agency theory context. The results show a picture with concentrated ownership where stock markets are relatively low important. Direct...
