J. S. Duesenberry's (1949) ratcheting consumption demand is derived as a feature of the optimal dynamic consumption and investment policy given extreme habit formation that prevents consumption from falling over time. Preferences are in effect non-time-separable, extended-real-valued von Neumann-Morgenstern preferences. Consumption increases each time wealth reaches a new maximum. Risky investment is proportional to the excess of wealth over the perpetuity value of current consumption. Extensions constrain the net rate of decrease in consumption with a constant other than zero, add more consumption goods, and constrain on the maximal holding of the risky asset as a proportion of wealth.

This paper considers a general version of the hold-up problem where n agents first make relation-specific investments and then must agree on some collective action. It is shown that first-best solutions exist under a variety of different assumptions about the nature of information asymmetries.

As a consequence of aggregation over markets, the observed quantity may be less than the quantity demanded and less than the quantity supplied. To deal with such situations, a new technique is proposed for estimating demand and supply curves and the extent of shortage and slack. The technique is applied to the consumption goods markets of Czechoslovakia, the German Democratic Republic, Hungary, Poland, and Yugoslavia. It is found that shortage, even corrected for a discouraged consumer effect, is seldom as great as slack.

Arguments in favour of self-enforced bans on advertising by professionals often rely on the stylized fact that advertising can communicate information about price but not about quality. This being the case, it is argued that allowing professionals to advertise runs the risk that firms will compete vigorously over price at the expense of the quality of their product. This paper shows that even if price can communicate no information directly about quality, it can do so indirectly because price will be a signal of quality. Because of this, allowing advertising is shown to improve consumer welfare.

A social choice procedure is developed for selecting an alternative from a finite set on the basis of paired-comparison voting. Ballot data are used to construct a lottery on the alternatives that is socially as preferred as every other lottery. The constructed lottery is then used to select a winner. An axiomatization of social preferences among lotteries that justifies the procedure is included. The procedure will always select a consensus majority alternative when one exists, and it will never select an alternative that is Pareto dominated by another alternative.
