We derive representations for the stock price drift and volatility in the equilibrium of agents with arbitrary, heterogeneous utility functions and with the aggregate dividend following an arbitrary Markov diffusion. We introduce a new, intrinsic characteristic of the aggregate dividend process that we call the ”rate of discounting volatility” and show that, in equilibrium, the size of market p...

Volatility characterizes the amplitude of price return fluctuations. It is a central magnitude in finance closely related to the risk of holding a certain asset. Despite its popularity on trading floors, volatility is unobservable and only the price is known. Diffusion theory has many common points with the research on volatility, the key of the analogy being that volatility is a time-dependent...

We present results from laboratory emissions markets designed to investigate the effects of price controls and permit banking on limiting permit price risk. While both instruments reduce between-period price volatility and within-period price dispersion, combining price controls and permit banking yields important benefits. Banking alone produces high permit prices in earlier periods that fall ...

We study a special form of securities market circuit breaker, i.e., European volatility interruptions. Instead of halt trading like traditional circuit breaker, these short-living call auctions allow for continual price discovery after price limit hits. Based upon approximately 1,800 Xetra volatility interruption events from 01/2009 to 01/2012, we empirically assess whether such auctions contri...

In many emerging stock markets, price limits are imposed on the magnitude of daily price movements. Price limit advocates claim that such limits serve as "circuit breakers" and decrease stock price volatility. Critics argue that the limits cause supply and demand imbalances in trading. Consequently, they prevent immediate corrections in price and increase the volatility of the opening return on...

In order to understand the origin of stock price jumps, we crosscorrelate high-frequency time series of stock returns with different news feeds. We find that neither idiosyncratic news nor market wide news can explain the frequency and amplitude of price jumps. We find that the volatility patterns around jumps and around news are quite different: jumps are followed by increased volatility, wher...
