A computational analysis of R&D support programs

We compare two common government R&D support programs, R&D tax credits and direct R&D grants. To study their effectiveness and the extent to which their design matters, we analyze these programs within a dynamic equilibrium model of imperfectly competitive industries. Adopting comprehensive welfare measures that take into account government, producer and consumer surpluses, we find that both schemes exhibit positive social returns. Mid-range R&D-intensive sectors exhibit higher social returns than either high or low R&D-intensive sectors. Both incentive schemes generate positive measures of R&D input additionality of magnitudes consistent with empirical R&D research. However, R&D grants that require firms to allocate subsidy funds to R&D spur less R&D than a more flexible R&D tax credit. Subsidy schemes can even induce competing firms to over-spend on R&D, generating negative producer surplus and possibly negative social returns.     

Financing R&D in mature companies: An empirical analysis

We study financing patterns of publicly traded R&D-intensive manufacturing firms in Israel. We further characterize R&D-intensive firms by size, physical capital intensity, and whether they issued stocks in the United States, asking whether these features are associated with particular financing patterns. To address these issues, we present, for the first time, adjusted flow of funds charts that treat R&D expenses as a capital outlay (rather than an operating cost that reduces profits, as standard accounting principles prescribe). We also address the question of how R&D inputs should be measured - using R&D expenses or R&D personnel. We construct both expenditure- and personnel-based R&D measures for each firm in our sample, and investigate to what extent these measures are mutually consistent.     

Homogeneity masquerading as variety: the case of horizontal innovation models

The literature on ‘horizontal innovation’ claimsto analyse cases where unbounded endogenous growth comes froman increasing variety of intermediate goods. The present papercontends that a good sample of representative models in thisliterature share two essential assumptions regarding productiontechnology, and that these assumptions together amount to assumingthe homogeneity of various intermediate goods. In these models,there is no variety of intermediate goods to increase owingto R&D activities; what increases is a mass of a singlehomogeneous intermediate good.     

Revisiting measure of R&D spillovers: empirical evidence on OECD countries and industries

Using data for 17 Organisation for Economic Co-operation and Development (OECD) countries over 29 years for 28 industries, this paper estimates industry-wise research and development (R&D) spillovers from the largest R&D investors and the most R&D-intensive industries that contribute 80% of global R&D. In doing so, it tests several assumptions made in the literature, and data rejecting them, proposes a methodology on R&D return estimation devoid of these assumptions. Results show that R&D has substantial spillovers, justifying R&D support policy. Each dollar of R&D generates about 29 cents in spillovers domestically and 4 cents in foreign countries. However, both intra- and inter-industry spillovers vary by industries, implying that the policy of supporting each R&D dollar uniformly across industries is suboptimal. Contrary to industry heterogeneity, the R&D spillovers from an industry do not vary substantially across countries, suggesting that optimal R&D policy across OECD countries might be uniform. An industry-by-industry technology matrix shows that sometimes an idea generates a greater impact on other industries than where it is generated.     

R&;D spillovers and firms’ performance in Italy

Using a translog production function we estimate the impact of R&D spillovers on the output performance of Italian manufacturing firms over the period 1998-2003. Technological flows are measured through an asymmetric similarity index that takes also into account the geographical proximity of firms. Results show that R&D spillovers positively affect firms production and that geography matters in determining the role of the external technology. Moreover, we find that the effect of R&D spillovers is high in the Centre-South of Italy and that the stock of R&D spillovers is Morishima complement to the stock of R&D own-capital.

Lower bounds of concentration in Taiwan's manufacturing industries: do exports matter?

This article aims to test Sutton's ‘lower bounds’ approach on the analysis of market concentration in a small open economy like Taiwan. Exporting, which is important to a small open economy, is also considered in order to investigate the role of foreign competition on the market structure. Using a stochastic frontier approach, the estimate findings are in accordance with Sutton's predictions, whereby the lower bounds for high advertising and/or R&D-intensive industries are higher than those for low advertising and/or R&D-intensive industries in Taiwan. At the same time, the lower bounds of concentrations for export-intensive industries do not differ significantly from that of nonexport-intensive industries. The deviations from the lower bound are explained by industry characteristics such as the cost disadvantage ratio, the share of small and median-size enterprises, turnover rate and growth rate.     

Wage formation in historical perspective: the French experience

Translator's note: In this article Robert Bayer introduces thenotion ‘regulation’ as a key concept in analysesof the labour market. The term refers to the balance of social,institutional and economic forces which characte rise at a particulartime the economic system as a whole or particular parts of it.I considered translating ‘regulation’ as ‘order’,‘regime’, ‘system’ or ‘formation’;but these terms are either too static or already bear inappropriateconnotations. It was therefore decided to retain the Frenchexpression in the English text.
