Enforcement by monitoring cannot be conditioned on the severity of an offense while enforcement by investigation can be. If some degrees of the offenses are not adequately reported or if investigation is too costly, the regulator must monitor and treat offenses of different severity quite differently. Smaller offenses should not be investigated; they should be deterred by monitoring alone, coupled with graduated fines. To deter larger offenses, the regulator should vary the investigation rate while setting maximal fines. Copyright 1992 by American Economic Association.

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.

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.

It is generally presumed that stronger legal enforcement of lender rights increases credit access for all borrowers because it expands the set of incentive compatible loan contracts. This result relies on an assumption that the supply of credit is infinitely elastic. In contrast, with inelastic supply, stronger enforcement generates general equilibrium effects that may reduce credit access for small borrowers and expand it for wealthy borrowers. In a firm-level panel, we find evidence that an Indian judicial reform that increased banks' ability to recover nonperforming loans had such an adverse distributive impact.

West Bengal potato farmers cannot directly access wholesale markets and do not knowwholesale prices. Local middlemen earn large margins; pass-through from wholesale to farmgate prices is negligible. When we informed farmers in randomly chosen villages about wholesale prices, average farmgate sales and prices were unaffected, but pass-through to farmgate prices increased. These results can be explained by a model where farmers bargain ex post with village middlemen, with the outside option of selling to middlemen outside the village. They are inconsistent with standard oligopolistic models of pass-through, search frictions, or risk-sharing contracts.
