Knowledge that Transforms

This paper models an economy in which risk-averse savers and risk-neutral entrepreneurs make investment decisions. Aggregate investment in high-yielding risky projects is maximized when risk-neutral agents bear all nondiversifiable risks. A role of banks is to assume nondiversifiable risks by pledging their capital in addition to diversifying risks. Banks, however, do not completely eliminate risks when monitoring by depositors is imperfect. Government deposit insurance that uses tax revenue to repay depositors transfers remaining risks to entrepreneurs. Deposit insurance can improve welfare because imperfect monitoring by the government largely results in income transfer among risk-neutral agents rather than lower production.Journal of Economic LiteratureClassification Numbers: G21, G28.

The variances of pricing errors (transitory changes in prices) at the NYSE open and the close are analyzed for U.S. stocks that are traded in London or Tokyo, British and Japanese stocks that are listed on the NYSE, and U.S. stocks that are not traded abroad. The variance of pricing errors is significantly greater at the open than at the close for U.S. stocks, but not foreign stocks. These differences are explained by differences in order flow at the open and the close, a relation that is the same whether stocks are foreign or domestic and whether they trade abroad or notJournal of Economic LiteratureClassification Numbers: G10, D23.

This paper presents an analytical model of underwriting capacity and insurance market equilibrium under an asymmetric corporate tax schedule characterized by incomplete tax-loss offsets. We show that reinsurance causes tax shields to be reallocated to those insurers that have the greatest capacity for utilizing them. Reinsurance is therefore used as an efficient short-run mechanism to yield the optimal allocation of tax shield benefits. In equilibrium, asymmetric taxes cause insurance prices to be actuarially unfair, and the expected return on capital invested in insurance reflects the probability of paying taxes.Journal of Economic LiteratureClassification Number: G22.
