We document an asset-pricing anomaly whereby companies have positive abnormal returns in months when they are expected to issue a dividend. We relate this to price pressure from dividend-seeking investors.

[Citation: Solomon, David H., 2012, ‘Selective Publicity and Stock Prices’, Journal of Finance 67 (2), 599-637, April 2012.]
Investor relations firms ‘spin’ their clients’ media coverage by getting more coverage of good news than bad news. This pushes up stock prices in the short term.

We find evidence of the disposition effect (the tendency to sell winners and hold on to losers) in a betting market on NFL games. Finding the disposition effect in a gambling market raises questions about what its underlying cause is.
[1.] A Multinomial Approximation of American Option Prices in a Lévy Process Model, 2006, with Ross A. Maller and Alexander Szimayer, Mathematical Finance
[Citation: Maller, Ross A ., David H. Solomon, and Alexander Szimayer, 2006, ‘A Multinomial Approximation of American Option Prices in a Lévy Process Model’, Mathematical Finance 16 (4), 613-633, October 2006.]
We develop a multinomial options pricing model that can price American options when the stock price follows an exponential Lévy process. The method works analogously to the binomial method, with the extra states allowing for price processes that include jumps.

Investors in most assets are more likely to sell gains than losses, but mutual fund investors do the opposite. Using experimental data, we argue that this is because selling losers means admitting to the mistake of the initial investment, but with delegated assets investors can blame the fund manager instead.

Using data from an NYSE firm, we find that investors who meet privately with company management have better performance in their trades. Interestingly, hedge funds seem to benefit from these meetings much more than mutual funds or pension funds.

We examine how much managers can increase media coverage of their firms. Releasing during the day increases coverage, but the major determinants of coverage are outside managerial control.

I look at a natural experiment where Sydney residents turned off lights and electrical appliances for an hour, and find this had very little impact on electricity use. Survey respondents also appeared to overstate their participation in the event.
