Using novel data on firms' government relations staff, and two distinct empirical settings, we show that political activism enables firms to grow their market power. The documented increases in profit margins and market share persist for up to two years, and are concentrated among large...

Contrary to the central predictions of signaling models, changes in profits do not empirically follow changes in dividends, and firms with the least need to signal pay the bulk of dividends. We show both theoretically and empirically that dividends signal safer, rather than higher, future...

Contrary to the central prediction of signaling models, changes in profits do not empirically follow changes in dividends. We show both theoretically and empirically that dividends signal safer, rather than higher, future profits. Using the Campbell (1991) decomposition, we are able to estimate...

Contrary to signaling models' central predictions, changes in profits do not empirically follow changes in dividends, and firms with the least need to signal pay the bulk of dividends. We show both theoretically and empirically that dividends signal safer, rather than higher, future profits....

Using a unique 10-year panel that includes more than 13,300 expected stock market return probability distributions, we find that executives are severely miscalibrated, producing distributions that are too narrow: realized market returns are within the executives' 80% confidence intervals only...
