Knowledge that Transforms

A dynamic model of corporate balance sheet structures and net worth growth is fit to firm-level panel data from Uruguay. Basic findings are: (1) net income is very sensitive to financial costs and demand for output; (2) there is a direct proportionality between net income and net worth expansion; (3) firms absorb most short-run fluctuations in net worth via adjustments in assets, not debts; and (4) the interest elasticity of corporate demand for peso debt is very small. Inter alia, these results imply that rapid changes in the exchange rate have large effects on corporate sector leverage and liquidity.

The ratio of a firm's market value to its replace ment cost, q, is often used to measure firms' profitability. The use of q is increasin g in large part because of the growing realization that errors in evaluating firms' capital assets may cause errors in estimates of the accounting rate of return, r. The same objection, however, applies t o q. This paper reports the results of Monte Carlo experiments designed to determine whether q is superior to r. Errors in both q and r are large and potentially serious, but do not render either measure useless.

Using level data from the U.S. steel industry, this paper tests and finds support for the hypothesis that firms in a contracting industr y first disinvest from, and then close, their high-cost plants. An investment decision model is estimated using a panel data set composed of the major replacement investments made in forty-three steel plants during the years 1960-81. The results indicate that the firms disinvested from those plants are least likely to remain profitable in an environment of strong competition from imports, minimills, and stagnating domestic demand.

The authors examine how the strategic aspect of Japanese research and development expenditures and industrial policies affected U.S.-Japanese bilateral trade during the late 1970s, and investigate which component of R&D--expenditures on process innovation, product quality improvements, new products and new technology, or technology transfer--proved to be most effective. They find that while Japanese R&D expenditures have generally promoted Japan's trade advantage, certain components of R&D have proved more effective than other. The depreciation subsidy and special status with the Ministry of International Trade and Industry is positively related to the Japanese trade performance, while legal cartelization status has not had any apparent effect.
