Recent research has shown that relaxing the assumptions of complete informationand common knowledge in exchange rate models can shed light on a wide range ofimportant exchange rate puzzles. In this chapter, we review a number of models wehave developed in previous work that relax the strong...

The paper is the first one outside the high-frequency domain to use sentiment-signednews to directly compare news and no-news stock returns. This is done by estimatingwhether returns on positive, neutral and negative news days are significantly differentfrom the average daily return for a large...

We explore the effects of information propagation in a centralized financialmarket. Specifically, we embed search frictions within the Grossman andStiglitz (1980) framework, relying on information percolation as modeled inDuffie, Malamud, and Manso (2009). First, we show that information...

Our purpose is to show how large difference of beliefs induced by fear of crashesis amenable to large and persistent price responses to contemporaneous shocks. Weconstruct a pure exchange economy populated by two agents who estimate strictlydifferent models regarding the fundamental. In...

This paper presents an equilibrium model in a pure exchange economywhen investors have three possible sources of heterogeneity. Investorsmay differ in their beliefs, in their level of risk aversion andin their time preference rate. We study the impact of investors heterogeneityon equilibrium...

We propose a technique to avoid spurious detections of jumps in highfrequencydata via an explicit thresholding on available test statistics. Weprove that it eliminates asymptotically all spurious detections. MonteCarlo results show that it performs also well in finite samples. In DowJones...

We calculate equilibria of dynamic double-auction markets in which agents aredistinguished by their preferences and information. Over time, agents are privatelyinformed by bids and offers. Investors are segmented into groups that differ withrespect to characteristics determining information...

We use a user-cost model to study how dispersed information among housing marketparticipants a¤ects the equilibrium house price. In the model, agents are disparatelyinformed about local economic conditions, consume housing services, and speculate onprice changes. Information dispersion leads...
