We characterize optimal enforcement in a setting in which individuals can select among various levels of some activity, all of which are monitored at the same rate but may be prosecuted and punished at varying rates. For less harmful acts, marginal expected penalties ought to fall short of marginal harms caused. Indeed, some range of very minor acts should be legalized. For more harmful acts, whether marginal expected penalties should fall short of, or exceed, marginal harms depends on the balance between monitoring and prosecution/punishment costs. We also explore how the optimal enforcement policy varies with changes in these costs.

We consider mechanism design in which message sets are restricted owing to communication costs, preventing full revelation of information. A principal contracts with multiple agents each supplying a one-dimensional good at a privately known cost. We characterize optimal mechanisms subject to incentive and communication constraints, without imposing arbitrary restrictions on the number of communication rounds. We show that mechanisms that centralize production decisions are strictly dominated by those that decentralize decision-making authority to agents, and optimal communication mechanisms maximize information exchanged directly among agents. Conditions are provided for these to involve gradual release of information over multiple rounds either simultaneously or sequentially.

This paper presents a theory of rent seeking within farmer cooperatives in which inequality of asset ownership affects relative control rights of different groups of members. The two key assumptions are constraints on lump‐sum transfers from poorer members and disproportionate control rights wielded by wealthier members. Transfers of rents to the latter are achieved by depressing prices paid for inputs supplied by members and diverting resulting retained earnings. The theory predicts that increased heterogeneity of landholdings in the local area causes increased inefficiency by inducing a lower input price and a lower level of installed crushing capacity. Predictions concerning the effect of the distribution of local landownership on sugarcane price, capacity levels, and participation rates of different classes of farmers are confirmed by data from nearly 100 sugar cooperatives in the Indian state of Maharashtra over the period 1971–93.
