This paper argues that regulatory institutions in defense procurement are (and necessarily must be) organized to create prizes for innovation in the form of positive economic profit on production contracts. This has a number of important policy implications. The values of the prizes on 12 major aerospace projects are estimated using stock market data and shown to be large.

Several recent studies have suggested that empirical rejections of the permanent income/life cycle model may be due to the existence of liquidity constraints. This paper tests the permanent income hypothesis against the alternative hypothesis that consumers optimize subject to a well-specified sequence of borrowing constraints. Implications for consumption in the presence of borrowing constraints are derived and then tested using time-series/cross-section data on families from the Panel Study of Income Dynamics. The results generally support the hypothesis that an inability to borrow against future labor income affects the consumption of a significant portion of the population.

Personnel managers often argue that equitable pay treatment manifested as wage compression is useful because it reduces disharmony among workers. But it is far from obvious that a compressed salary structure is morale improving since better workers may feel disenchanted by this scheme. However, when workers' rewards are based on relative comparisons, salary compression reduces uncooperative behavior that is detrimental to the firm. Relative comparisons imply that some reference group must be selected. The major result is that within the relevant groups, some wage compression is efficient.
