The quality of a marriage depends on the proximity of a collective action to a unknown target. Individuals receive private signals about the target, and can communicate them only imperfectly to their spouses. Because of imperfect communication, spouses may hold different beliefs about the optimal action. If a couple's beliefs diverge too widely, one or both of them may prefer to dissolve the marriage. The article explores how poor communication contributes to marital unhappiness, as well as its implications for the dynamics of divorce risk, the welfare properties of divorce decisions and the role of counselling.
