Dividend Neutrality with Transaction Costs

I construct an intertemporal model in which investors trade shares of a firm. All trading is done through competitive market makers. After the initial period and before the end of the planning horizon, information is asymmetrically distributed among traders, and the prices for investors who buy shares are higher than for those who sell shares. The presence of this deviation from the Walrasian paradigm notwithstanding, dividend policy does not affect the initial period's share price or shareholders' welfare. This result is robust to various extensions of the model. I also consider fixed administrative transaction costs and show that dividend policy is irrelevant in the presence of these transaction costs.
