The empirical analysis in "International R&D Spillovers" (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results reported in Coe and Helpman about the impact of domestic and foreign R&D capital stocks on TFP. In addition, we show that domestic and foreign R&D capital stocks have measurable impacts on TFP even after controlling for the impact of human capital. Furthermore, we extend the analysis to include institutional variables, such as legal origin and patent protection, in order to allow for parameter heterogeneity based on a country's institutional characteristics. The results suggest that institutional differences are...

|The Credit Crunch in East Asia: What can Bank Excess Liquid Assets Tell us?|
with , : w7951
The paper proposes a two-step approach to assessing the extent to which the fall in credit in crisis-stricken East Asian countries was a supply- or demand-induced phenomenon. The first step is based on the estimation of a demand function for excess liquid assets by commercial banks. Such a function is derived analytically in the first part of the paper. The second step consists in establishing dynamic projections for the periods following the crisis and assessing whether or not residuals are large enough to be viewed as indicators of involuntary' accumulation of excess reserves. Results for Thailand indicate that the contraction in bank lending that accompanied the crisis was the result of supply factors.

|Contagion, Bank Lending Spreads and Output Fluctuations|
with , : w6850
This paper studies the effects of contagion on bank lending spreads and output fluctuations in Argentina. The first part presents the analytical framework, which analyzes the determination of bank lending spreads in the presence of verification and enforcement costs of loan contracts. The second part presents estimates of a vector autoregression model that relates the ex ante bank lending spread, the cyclical component of output, the real bank lending rate, and the external interest rate spread. The effects of a contagious shock (modeled as a positive historical shock in the external interest rate spread) are analyzed using generalized impulse response functions. The sock is shown to lead to an increase in domestic spreads and a reduction in the cyclical component of output. These res...
|North-South R&D Spillovers|
with David T. Coe, : w5048
We examine the extent to which developing countries that do little, if any research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has large 'stocks of knowledge' from its cumulative R&D activities, a developing country can boost its productivity by importing a larger variety of intermediate products and capital equipment embodying foreign knowledge, and by acquiring useful information that would otherwise be costly to obtain. Our empirical results, which are based on observations over the 1971-90 period for 77 developing countries, suggest that R&D spillovers from the industrial countries in the North to the developing countries in the South are substantial.
