We analyze how markets adjust to new information when the reliability of news is uncertain and has to be estimated itself. We propose a Bayesian learning model where market participants receive fundamental information along with noisy estimates of news' precision. It is shown that the efficiency...

Bayesian learning provides the core concept of information processing in financial markets. Typically, it is assumed that market participants know perfectly the quality of released news. However, in practice, news' precision is rarely disclosed. Therefore, we extend standard Bayesian learning,...

Bayesian learning provides the core concept of processing noisy information. In standard Bayesian frameworks, assessing the price impact of information requires perfect knowledge of news’ precision. In practice, however, precision is rarely dis- closed. Therefore, we extend standard Bayesian...

Obwohl viele im Bereich Sozialunternehmertum forschende Wissenschaftler auf Fälle von "Mission Drift" hinweisen, gibt es derzeit keine Erklärung für dieses Phänomen. Sozialunternehmen sind Organisationen, die gleichzeitig zwei Ziele verfolgen: die Erzielung von Einnahmen und die Maximierung...

For years, businesses have complained about the costs of regulatory compliance. On the other hand, society is becoming increasingly aware of the environmental, safety, health, financial, and other risks of business activity. Government oversight seems to be one of the answers to safeguard...
