We generalize the prevailing theoretical models that estimate the discount on securities for lack of marketability, by considering the discrete trading frequency of the securities. The generalization shows that accounting for the illiquidity of securities may significantly reduce their...

We estimate the value of restricted stock (RS) grants to non-executive employees using a unique proprietary database by calibrating theoretical models that account for the non-marketability of securities and the potential effects of the employee's non-diversification. The calibration results...

We investigate the trading of corporate bonds (c-bonds) by an open limit order book (LOB) mechanism. To do so, we use the case of the Tel Aviv Stock Exchange (TASE) as a laboratory, in which both stocks and c-bonds are traded by an LOB mechanism. Contrary to the OTC market in the US, the TASE...

We examine changes in controlling shareholder holdings, looking for evidence of financial tunneling (unfair wealth transfers from public investors to controlling shareholders). Our sample comprises yearly data during 2000-2011 on 75 large Israeli companies. We find that controlling shareholders...

We investigate daily flows to Israeli mutual funds, which are held primarily by retail investors. We find that daily net flows are contemporaneously correlated with price changes of all government bond categories (nominal/CPI-linked; short-term, intermediate-term, and long-term maturity). These...

This paper constructs a closed-form generalization of the Black-Scholes model for the case where the short-term interest rate follows a stochastic Gaussian process. Capturing this additional source of uncertainty appears to have a considerable effect on option prices. We show that the value of...

We examine differences in audit scope between family and non-family firms in Israel, using a unique database that includes both external and internal audit fees, hours, and billing rates. Consistent with prior literature, we argue that the number of audit hours reflects an auditor’s effort,...

We find significant positive abnormal returns surrounding a surprising and quick enactment of a law that restricts executive pay to a binding upper limit in a few industries. We find that the effect is concentrated only for firms in which the restriction is binding. We also find that the...

We adapt the Benninga-Helmantel-Sarig (2005) framework to value employee stock options (ESOs). The model quantifies non-diversification effects, is computationally simple, and provides an endogenous explanation of ESO early-exercise. Using a proprietary dataset of ESO exercise events we measure...
