We model theoretically the optimal capital structure of entrepreneurial firm relying on an endogenous estimation of the return requested by entrepreneurs that compensates for the risk they incur in case of bankruptcy. We estimate the probability according to the Bayesian approach. We also...

This paper examines how high-frequency trading decisions of individual investors are influenced by past price changes. Specifically, we address the question as to whether decisions to open or close a position are different when investors already hold a position compared to when they don't. Based...

This paper develops the idea of renewal time sampling, a novel sampling scheme constructed from stopping times of semimartingales. Based on this new sampling scheme we propose a class of volatility estimators named renewal based volatility estimators. In this paper we show that: (1) The spot...

We develop a Markov-Switching Autoregressive Conditional Intensity (MS-ACI) model with time-varying transitional parameters, and show that it can be reliably estimated via the Stochastic Approximation Expectation-Maximization algorithm. Applying our model to high-frequency transaction data, we...

This paper provides field evidence that social distance between customers and reviewers influences the impact from online reviews on product sales. We conceptualize information on interpersonal similarity as a heuristic cue that helps customers to infer similarity in product preferences between...

Equal-weighted (EW) portfolios have outperformed their value-weighted (VW) counterparts over multiple decades in various investment universes. This paper investigates the long-term evidence or the EW–VW return spread in a broad U.S. equity universe across multiple factor models....

Investors face similar macroeconomic risks and opportunities regardless of their individual investment preferences. To best navigate growth and inflation concerns, we propose building macro factor-mimicking portfolios diversified across asset classes and style factors. We focus on the macro...

We propose a new approach to examine sell-side analysts' career concerns by relating their forecast boldness to their employers' news flows. Specifically, we use banking sector news to proxy for the severity of career concerns. Analysts follow more closely the consensus forecast when the...

This paper investigates the behavior of crude oil prices, government bonds and stock market indices around outbreaks of severe international crises and wars. Using a constant-mean-return event study, we show that these events are associated with positive and significant abnormal returns on oil...

In this paper we provide evidence that the trading activity of small retail investors carries significant genuine information for the short term out-of-sample forecasting of foreign exchange rates. Our findings are based on a unique dataset of around 2000 retail investors from the OANDA FXTrade...
