Energy Prices and Induced Technological Progress

Kumar, Surender - In: Economics Bulletin 15 (2008) 17, pp. 1-15

This study measures energy price induced technological change using directional distance function for a panel data of 55 countries over the period 1974 to 2000. The parameter estimates of directional distance function reveal the absence of neutral exogenous innovations and the presence of biased...

Technological spillover and the time distribution of licenses

Ottoz, Elisabetta - In: Economics Bulletin 15 (2005) 15, pp. 1-10

The aim of this note is to study the optimal licensing of a non drastic cost reducing patented innovation, if the … holder prefers exclusive innovation exploitation, giving rise to a monopoly, non exclusive exploitation giving rise to a … early simultaneous adoption, whereas diffusion, implying asymmetric adoption, is better if the innovation implies a more …

Policy implications of endogenous growth models: A Note

Lingens, Joerg - In: Economics Bulletin 15 (2005) 13, pp. 1-7

In this note we analyse the effect of an increase in the amount of resources devoted to research within a general R&D growth model. We show that the initial effect of this increase is independent of whether the spill-over in R&D is linear or not. Even after two decades along a transitional...

A Note on the Persistence of Firms' Innovation Behavior: A Dynamic Random Effect Probit Model Approach

Huang, Chia-Hui - In: Economics Bulletin 15 (2008) 5, pp. 1-9

Is firms' innovation behavior persistent? Using both patent and R&D intensity as proxy variables of innovation and … dependence after controlling for the firm heterogeneity. This result indicates that there is a causal effect from past innovation … to current innovation, supporting the hypothesis of persistent innovation. …

Communication costs, network externalities, and long-run growth

Davis, Colin - In: Economics Bulletin 15 (2007) 5, pp. 1-9

This note examines the effect of per-period communication costs in a model of expanding product variety. It is shown that while a decrease in communication costs leads to growth in aggregate output, this growth is only transitional with the growth rate falling to zero in the long run as the...

Technology adoption in a community of heterogeneous education level: Who are your good neighbors?

Ono, Yusuke - In: Economics Bulletin 15 (2006) 8, pp. 1-11

This paper examines the role of education in technology adoption in a multi-agent finite-time dynamic game setting. It is assumed that education decreases prior variance on the best action in using a new technology in the target-input Bayesian model, experience accumulates in a community (social...

Knowledge diffusion under patent with asymmetric firms

Mukherjee, Arijit; Sinha, Uday Bhanu - In: Economics Bulletin 12 (2007) 9, pp. 1-6

We show that if patent protection and trade secrecy generate asymmetric market structure, an innovator may prefer patent protection than trade secrecy even if the diffusion probability is higher under the former but it increases market concentration by preventing some imitators. So, whether an...

Innovation, Firm Size, and R&D Search

Plehn-Dujowich, Jose - In: Economics Bulletin 12 (2007) 18, pp. 1-8

We present evidence that small firms perform two to four times more innovations per dollar of R&D than large firms. We propose a search theory of R&D that accounts for the evidence. A firm incurs R&D expenses until it has discovered a level of R&D productivity that is sufficiently great to...

Final Goods Substitutability and Economic Growth

Oikawa, Koki - In: Economics Bulletin 15 (2007) 16, pp. 1-7

In this paper, I investigate the effect of substitutability among final goods on welfare growth under the environment that productivity growth in each industry is not independent of one another. In such an environment, less substitutability is favorable to the welfare growth rate and the steady...

Barriers to technology adoption, international R and D spillovers and growth

Foster, Neil; Scharler, Johann; Crespo-Cuaresma, Jesus - In: Economics Bulletin 15 (2008) 3, pp. 1-7

Panel data is used to investigate the extent of R and D spillovers between OECD countries, and the importance of barriers to technology adoption in affecting the benefits of such spillovers. Our results indicate that countries with less regulated goods and labour markets benefit more from...
