Two basic tenets of the Walrasian model, behavior based on self-interested exogenous preferences and complete and costless contracting have recently come under critical scrutiny. First, social norms and psychological dispositions extending beyond the selfish motives of Homo economicus may have an important bearing on outcomes, even in competitive markets. Second, market outcomes depend on strategic interactions in which power in the political sense is exercised. It follows that economics must become more behavioral and more institutional. We can return to these themes of the classical tradition, now equipped with the more powerful mathematical tools developed over the past century.

This paper is concerned with asymptotic properties on the accuracy of numerical solutions. It is shown that the approximation error of the policy function is of the same order of magnitude as the size of the Euler equation residuals. Moreover, for bounding this approximation error the most relevant parameters are the discount factor and the curvature of the return function. These findings provide theoretical foundations for the construction of tests to assess the performance of alternative computational methods.

This paper develops optimal pricing, lending, and renegotiation strategies for companies in relationships where one firm is highly dependent on the other. Long‐term trade—creditor firm relationships induce dependent trade creditors to grant more concessions in debt renegotiations than nondependent creditors. Anticipating these larger renegotiation concessions, not only do less financially stable firms prefer trade credit, but all firms agree to pay a higher interest rate for trade credit. The model also explains the existence of “teaser” interest rates and convenience classes. Findings are consistent with those of the relationship‐lending literature.

In this paper, we examine empirically whether credit plays a role as a nonlinear propagator of shocks. This propagation takes the form of a threshold vector autoregression in which a regime change occurs if credit conditions cross a critical threshold. Using nonlinear impulseresponse functions, we evaluate the dynamics implied by the threshold model. These suggest that shocks have a larger effect on output in the ''tight'' credit regime than is normally the case, and that contractionary monetary shocks typically have a larger effect than expansionary shocks. Finally, using a nonlinear version of historical decompositions, we attempt to determine the relative contribution to output growth of shocks and the nonlinear structure.

Work by Kaplan and Zingales provides both theoretical arguments and empirical evidence that investment-cash �ow sensitivities are not good indicators of �nancing constraints. Fazzari, Hubbard, and Petersen {this Journal} criticize those �ndings. In this note we explain how the Fazzari et al. criticisms are either very supportive of the claims in earlier work by Kaplan and Zingales or incorrect. We conclude with a discussion of unanswered questions. Fazzari, Hubbard, and Petersen {1988} (hereinafter, FHP {1988}) introduce a methodology to identify the presence of �nancing constraints based on the differential sensitivity of corporate investment to cash �ow. Kaplan and Zingales {1997} (hereinafter, KZ) provide both theoretical arguments and empirical evidence that this differential sensitivity is not a valid measure of �nancing constraints. Fazzari, Hubbard, and Petersen {2000} (hereinafter, FHP {2000}) criticize those �ndings. In this note we explain that the main arguments in FHP {2000} are, in fact, quite supportive of KZ’s main conclusion, while the speci�c criticisms in FHP {2000} are unjusti�ed. I. POINTS OF AGREEMENT FHP {2000} admit that �nancially distressed �rms are likely to have lower investment-cash �ow sensitivities than less �nancially constrained �rms. This is exactly the point that the KZ model makes: investment-cash �ow sensitivities are not necessarily monotonic in the degree of �nancing constraints. The only disagreement FHP {2000} have with KZ is how pervasive the nonmonotonicity result is. But this is ultimately an empirical question. FHP {2000} also recognize that the literature on investmentcash �ow sensitivities has not been based on a solid theoretical foundation. As KZ point out, the practice of (1) splitting the sample according to a measure of �nancing constraints and then

The Japanese banking crisis provides a natural experiment to test whether a loan supply shock can affect real economic activity. Because the shock was external to U.S. credit markets, yet connected through the Japanese bank penetration of U.S. markets, this event allows us to identify an exogenous loan supply shock and ultimately link that shock to construction activity in U.S. commercial real estate markets. We exploit the variation across geographically distinct commercial real estate markets to establish conclusively that loan supply shocks emanating from Japan had real effects on economic activity in the United States.
