We examine the role of generalized constant gain stochastic gradient (SGCG) learning in generating large deviations of an endogenous variable from its rational expectations value. We show analytically that these large deviations can occur with a frequency associated with a fat tailed...

Physicians prescribing drugs for patients with schizophrenia and related conditions are remarkably concentrated in their choice among antipsychotic drugs. In 2007 the single antipsychotic drug prescribed by a physician accounted for 66% of all antipsychotic prescriptions written by that...

Three striking empirical regularities have been repeatedly reported: the positive correlation between housing prices and trading volume, between housing price and the time-on-the-market (TOM), and the existence of price dispersion. This short paper provides perhaps the first unifying framework...

We develop a framework that allows us to reproduce the generalised agreement theorem of Samet (2010), and extend it to models with a non-partitional information structure, while highlighting the features that distinguish the result from the classic theorems found in the literature. Furthermore,...

We develop a framework that allows us to emulate standard results from the “agreeing to disagree" literature with generalised decision functions (e.g. Bacharach (1985)) in a manner the avoids known incoherences pointed out by Moses and Nachum (1990). We analyse the implications of the...

We model an interaction between an informed sender and an uninformed receiver. As in the classic cheap talk setup, the informed player sends a message to an uninformed receiver who is to take an action which affects the payoffs of both players. However, in our model the sender can communicate...

We incorporate semiotics into economic theory, modeling communication with an encoding-decoding step where the sender transmits a message that the receiver can understand if and only if a common natural language is used. We add an inferential step where the receiver may either believe the...

We analyze whether mid-level managers in securitized finance were aware of a large-scale housing bubble and a looming crisis in 2004-2006 using their personal home transaction data. We find that the average person in our sample neither timed the market nor were cautious in their home...

This paper presents a sequential search model where consumers look for several products from multiproduct firms. Multiproduct search can significantly influence firms' pricing decisions. For example, it can make market prices decrease with search costs. Possible applications of the model are...

We study the strategic disclosure of demand information and product-market strategies of duopolists. In a setting where firms may fail to receive information, we show that firms selectively disclose information in equilibrium in order to influence their competitor’s product-market strategy....
