Recent empirical research in finance has uncovered two families of pervasive regularities: underreaction of stock prices to news such as earnings announcements, and overreaction of stock prices to a series of good or bad news. In this paper, we present a parsimonious model of investor sentiment, or of how investors form beliefs, which is consistent with the empirical findings. The model is base...

This paper proposes that bank runs are unique equilibrium outcomes instead of self-fulfilling prophecies. By assuming that depositors make their withdrawal decisions sequentially, the model provides an equilibrium-selection mechanism in the economy. A bank run would occur if and only if depositors perceive a low return on bank assets. Furthermore, a panic situation arises only when the market i...

We argue that arbitrage is limited if rational traders face uncertainty about when their peers will exploit a common arbitrage opportunity. This synchronization risk—which is distinct from noise trader risk and fundamental risk—arises in our model because arbitrageurs become sequentially aware of mispricing and they incur holding costs. We show that rational arbitrageurs ‘‘time the market’’ rat...

In this paper we provide empirical findings on the significance of positive feedback trading for the return behavior in the German stock market. Relying on the ShillerSentana-Wadhwani model, we use the link between index return auto-correlation and volatility to obtain a better understanding into the return characteristics generated by traders adhering to positive feedback trading strategies. O...

Motivated by psychological evidence that attention is a scarce cognitive resource, we model investors’ attention allocation in learning and study the effects of this on asset-price dynamics. We show that limited investor attention leads to category-learning behavior, i.e., investors tend to process more market and sector-wide information than firm-specific information. This endogenous structure...

Donald Trump’s election was a significant surprise. The reaction of company stock prices to the election reflects shifts in investor expectations about economic growth, taxes, and trade policy. High-beta stocks outperformed, presumably due to strengthened growth expectations. Expectations of significant corporate tax cuts boosted high-tax firms, but hurt firms with significant net operating los...

A total of 12 diverse tomato genotypes as parents and their 32 hybrids, obtained through Line × tester mating fashion, were evaluated to observe the consequence different genetic parameters on yield contributing traits. The experiment was conducted during two consecutive years 2016-2017 2017-2018 winter seasons in a Randomized Complete Block Design (RCBD) with three replications. analysis varia...

This article offers a dynamic model of opaque over-the-counter markets. A seller searches for an attractive price by visiting multiple buyers, one at a time. The buyers do not observe contacts, quotes, or trades elsewhere in the market. A repeat contact with a buyer reveals the seller’s reduced outside options and worsens the price offered by the revisited buyer. When the asset value is uncerta...

A dynamic model of financial markets with learning is demonstrated to produce a selforganized system that displays critical behavior. The price contains private information that traders learn to extract and employ to forecast future value. Since the price reflects the beliefs of the traders, the learning process is self referencing. As the market learns to correctly extract information from the...
