We show that Tobin's q, as proxied by the ratio of the firm's market value to its book value, increases with the firm's systematic equity risk and falls with the firm's unsystematic equity risk. Further, an increase in the firm's total equity risk is associated with a fall in q. The negative relation between the change in total risk and the change in q is robust through time for the whole sampl...

This paper builds on the landmark contribution of Glosten (1994) by treating the determination of limit order supply schedules as an exercise in asset pricing theory with the possible sizes of incoming market orders as the value-relevant states of nature, yielding an analogue of the Fundamental Theorem of Asset Pricing. State prices and price impact prove to be proportional to the slope of the ...

When interest rate dynamics are described by the Libor Market Model as in Brace, Gatarek & Musiela (1997), we show how some essential risk-management results can be obtained from the dual of the calibration program. In particular, if the objetive is to maximize another swaption’s price, we show that the optimal dual variables describe a hedging portfolio in the sense of Avellaneda & Paras (1996...

In this paper, we model cash flow and consumption growth rates as a vectorautoregression (VAR), from which we measure the response of cash flow growth to consumption shocks. As the appropriate cash flow proxy is not unambiguous, nor likely to be measured without error, we consider three alternatives for portfolio cash flows: cash dividends, dividends plus repurchases and corporate earnings. We ...

In this work we analyze market payoffs of Credit Default Swaps (CDS) and we derive rigorous standard market formulas for pricing options on CDS. Formulas are based on modelling CDS spreads which are consistent with simple market payoffs, and we introduce a subfiltration structure allowing all measures to be equivalent to the risk neutral measure. Then we investigate market CDS spreads through c...

The demand for electronic books (e-books) and the e-book readers are complementary. On the one hand, the emergence of e-book readers such as Amazon’s Kindle has triggered the recent growth of the e-book market. On the other hand, several issues in the e-book market can affect the future of the e-book reader market. Considering this complementarity, this paper quantifies the impact of digital ri...

In its October 2013’s consultative paper for a revised market risk framework (FRTB), the Basel Committee suggests that non-securitization credit positions in the trading book be subject to a separate Incremental Default Risk (IDR) charge, in an attempt to overcome practical challenges raised by the joint modeling of the discrete (default risk) and continuous (spread risk) components of credit r...

The paper shows that lottery-like stocks are hedges against unexpected increases in market volatility. The loading on the aggregate volatility risk factor explains low returns to stocks with high maximum returns in the past (Bali, Cakici, and Whitelaw, 2011) and high expected skewness (Boyer, Mitton, and Vorkink, 2010). Aggregate volatility risk also explains the new evidence that the maximum e...
