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....

This article provides a procedure for the estimation of parametric homogeneous stochastic volatility (SV) pricing formulae based on option data. Our estimator has the advantage of being (i) based on option data, (ii) easy to implement in practice, (iii) with clear statistic properties and (iv)...

We extend the pioneering work of Aumann–Serrano by presenting an index of riskiness for gambles with either positive or negative expectations. It can be of use for a variety of abstract behaviors, when adapting the framework of either Expected-Utility Theory or Prospect Theory.

This paper analyzes stock-price volatility in the presence of periodically collapsing Evans bubbles. We derive a volatility formula that establishes a link between the bubble component and stock-price volatility. We demonstrate how to fit the volatility equation to stock-market data.

We present processes on stock exchange as two random processes one of which reflects the regular regime of economy and the other one–crises. If regular processes are correctly recognized with the probability slightly higher than 1/2, this gives positive average gain to the player. We believe...

This paper re-examines the empirical results of Cochrane and Piazzesi (2005). After taking into account the sample information about forward rates, we still support their empirical findings.
