In this note, we consider the effect on equity premiums of a representative household’s subjective expectations during disasters. In particular, we focus on the effect of doubt during disasters. We derive analytical solutions of equity premiums in the model of power utility function and...

We analyze a simple model of an asset market, in which a large rational trader interacts with “noise speculators” who seek short-run speculative gains, and become active following a prolonged episode of mispricing relative to the asset’s fundamental value. The model gives rise to price...

We hypothesize the existence of a slow-moving fad component in art prices. Using unique panel survey data on art market participants’ confidence levels in the outlook for a set of artists, we find that sentiment indeed predicts short-term returns.

In this paper, we quantify the dynamics of absolute excess returns on stock markets depending on three factors: the average of the absolute excess return, the level of the stock price, and stock market volatility. We also argue that the absolute excess return can be regarded as an empirical...

We compare post-financing stock performance for debt-issuing portfolio with equity-issuing one in Taiwan to identify whether firms’ financing decisions were driven by managerial optimism or market timing. Our result supports corporate financing decisions in Taiwan are driven by managerial...

This experiment shows that varying the commission received by financial advisors strongly influences insurance purchase.

While theory of autoregressive conditional heteroskedasticity (ARCH) models is well understood for strictly stationary processes, some recent interest has focused on the nonstationary case. In the classical model including a positive intercept parameter, the volatility process diverges to...

Novel data-driven analyses, appropriate for detecting economic instability in non-stationary time series, are developed using functional principal component analysis (fPCA) and Synchrosqueezing. fPCA is applied in a new way, aggregating multiple financial time series to identify periods of...

This article tests the linearity assumption underlying the popular heterogeneous autoregressive model for realized volatility (HAR-RV). We implement a consistent model specification test that is robust to both distributional and model misspecification. We find that, using a nonparametric HAR-RV...

We show that structural changes in stochastic volatility models induce spurious persistence. Other than in GARCH-type models, implied persistence does not tend to unity with given size of the structural change and increasing sample size.
