In this paper, we propose an innovative VIX model which takes future market information available to the traders into account. The future information is modeled by an initially enlarged filtration in our setup. We derive an explicit representation for the anticipative VIX process and obtain the...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond. The financial market is assumed to be incomplete and the option is not a redundant asset. In such a case the...

We study individual coherent preferences underlying asset prices and propose a set of explicit models for nonlinear V-shaped price pressure utility in a new framework. Coherent preferences are consistent interactive choices between momentum trading and reversal trading in stock market where...

It is often believed that markets with more experienced investors exhibit fewer bubbles. The same is believed of markets where investors have additional information about fundamentals. We provide evidence that both is not necessarily true. In contrast, bubbles may rise faster in markets with...

This paper investigates the time-varying dynamics of global stock volatility, commodity prices, and domestic output and consumer prices. The main empirical findings of this papers are: (i) stock volatility and commodity price shocks impact each other and the economy in a gradual and endogenous...

We decompose global stock market volatility shocks into financial originated shocks and non-financial originated shocks. Global stock market volatility shocks arising from financial sources reduce substantially more global outputs and inflation than non-financial sources shocks. Financial stock...

This paper investigates how the disclosure tone of earnings conference calls predicts future stock price crash risk. Using U.S. public firm earnings conference call transcripts from 2010 to 2015, we find that firms exhibiting more pessimistic tone during the current year-end call experience...

We study the economic determinants of the information externality suppliers experience at the time of their customers' quarterly earnings announcements (QEAs). We measure the information externality as suppliers' stock price reaction to their customers' QEAs. We expect information externalities...

We propose a dynamic asset-market equilibrium model in which (1) an "innovative" asset with as-yet-unknown average payoff is traded, and (2) investors delegate investment to experts. Experts secretly renege on investors' orders and take on leveraged positions in the asset to manipulate...
