We identify the conditions where robust mean–variance preferences, which capture ambiguity aversion, are observationally nonequivalent to subjective mean–variance preferences. Conversely, we also provide an example showing that observational equivalence holds regardless of the degree of...

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

The paper develops a housing deep-habit model to explore linkages between macroeconomic decisions and asset pricing of nondurable and housing goods. Owing to heterogeneous characteristics of housing assets, the model sheds insights into the counter-cyclical property of housing markups.

This paper shows that when Value-at-Risk constrained institutional investors care about their relative standings among the peer group, more risk averse investors would take more risk, which improves the risk sharing and lowers the volatility.

Two recent asset pricing models share a common core of the addition of profitability and investment as factors, but differ in implementation. We adapt these models for the UK and argue that the Fama–French five-factor profitability factor offers the most potential.

I examine if the 2009 bank stress test conducted by the Federal Reserve conveyed new information to investors. By analyzing bank bond returns, I show that the announcement of the bank stress test results mitigated information asymmetries in US banks.

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 find that an expansion of credit has a positive effect on per capita output growth only up to a point. Beyond this threshold the impact of finance on growth is not statistically significant anymore. We show, however, that the estimated non-linear relationship may stem from the omission of...

This paper extends Hong et al. (2007)’s model-free test to analyze the contagion. A simulation experiment reveals that our test has reasonable size and good power in finite sample. We use this test and find the strong evidence of contagion between crude oil and stock markets.

Amid its rapidly increasing usage and immense public interest the subject of Bitcoin has raised profound economic and societal issues. In this paper we undertake economic and econometric modelling of Bitcoin prices. As with many asset classes we show that Bitcoin exhibits speculative bubbles....
