Volatility Inference and Return Dependencies in Stochastic Volatility Models [PDF]
Stochastic volatility models describe stock returns $r_t$ as driven by an unobserved process capturing the random dynamics of volatility $v_t$. The present paper quantifies how much information about volatility $v_t$ and future stock returns can be inferred from past returns in stochastic volatility models in terms of Shannon's mutual information.

Due to the increasing demand and growing importance of resilient and sustainable supply chains, the use of recycled and reused Nd–Fe–B magnets in e‐mobility applications such as Pedelecs, e‐Scooters, and Hoverboards is being investigated. It can be shown that the corresponding motors with recycled magnets do not exhibit any loss of performance while at

Asymmetric Volatility and Risk in Equity Markets
It appears that volatility in equity markets is asymmetric: returns and conditional volatility are negatively correlated. We provide a unified framework to simultaneously investigate asymmetric volatility at the firm and the market level and to examine ...

Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Emerging Equity Market Volatility
Returns in emerging capital markets are very different from returns in developed markets. While most previous research has focused on average returns, we analyze the volatility of the returns in emerging equity markets. We characterize the time-series of

Ferroelectric ZrO2 films grown by sputtering on Si, show strong near‐infrared (NIR) detection capability. The performance is shown to arise from the pyroelectric effect, combined with the ferroelectric effect in ZrO2, and the photovoltaic effect in Si.
