Most empirical models of investment rely on the assumption that firms are able to respond to prices set in centralized securities markets (through the "cost of capital" or "q"). An alternative approach emphasizes the importance of cash flow as a determinant of investment spending, because of a...

Kaplan and Zingales (1995, hereafter KZ) criticize Fazzari, Hubbard and Petersen (1988, hereafter FHP) and much ensuing research that uses cross-sectional differences in firm behavior to test for financing constraints on investment. This reply identifies flaws in the KZ analysis. The questions...

While output declined in virtually all transition economies in the initial years, the speed and extent of the recovery that followed has varied widely across these countries. The contrast between the more and less successful transitions, the latter largely in the former Soviet Union, raises many...

It is often argued that the most important costs of inflation can be substantially mitigated by indexing reforms. Yet governments in moderate inflation countries have generally been very reluctant to promote institutional changes that would reduce the costs of inflation. Capital income continues...
