We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

Economists and financial analysts have begun to recognise the importance of the actions of other agents in the decision-making process. Herding is the deliberate mimicking of the decisions of other agents. Examples of mimicry range from the choice of restaurant, fashion and financial market...

This paper examines how monetary expansion causes asset bubbles. When there is no monetary expansion, a bubbly asset is not created due to a hold-up problem. Monetary expansion increases buyers' money holdings, and then, dealers are willing to buy a worthless asset from sellers, in hopes of...

Starting from basic hypotheses on how footprints from hidden orders are interpreted by short-term traders, we derive a fair price model that predicts market impact for non-uniform participation rate schedules. We use this model to derive an optimal execution schedule for a risk-averse trader....

In a market with informationally connected traders, the dynamics of volume, price informativeness, price-volatility, and price-impacts are severely affected by the number of information linkages every trader experiences with his neighbors. We show that in the presence of information linkages...

Investors who possess the same information and interpret it differently are said to have divergent (as distinct from) homogeneous expectations. Financial economists have widely frowned on the divergent expectations assumption. Nevertheless, this assumption describes reality and is critically...

In this paper, we develop a model of earnings management that sheds light onto empirical regularities in the behavior of institutions and insiders. We link the earnings management decision to insiders' stake and show how this may impact analysts' forecast accuracy and institutional trading. More...

This paper develops a market microstructure model with asymmetric information in order to quantify the influence which practical decision rules have on asset prices. The users of practical decision rules have incomplete information at their disposal and trade in a market with both fully informed...

Using an intertemporal model of asset pricing under asymmetric information, we demonstrate how public ratings about the quality of a risky asset could enhance information efficiency, albeit at a cost of higher asset price volatility. The analysis also draws implications for the use of ratings...
