Demand,innovation, and the dynamics of market structure: The role of experimental users and diverse preferences 总被引:2,自引:1,他引:1
Franco Malerba Richard Nelson Luigi Orsenigo Sidney Winter 《Journal of Evolutionary Economics》2007,17(4):371-399
The history of a number of industries is marked by a succession of eras, associated with different dominant technologies.
Within any era, industry concentration tends to grow. Particular eras are broken by the introduction of a new technology which,
while initially inferior to the established one in the prominent uses, has the potential to become competitive. In many case
new entrants survive and grow, and the large established firms do not make the transition. In other cases, the established
firms are able to switch over effectively, and compete in the new era. This paper explores a model which generates this pattern
and has focused on the characteristics of the demand. We argue that the ability of the new firms exploring the new technology
to survive long enough to get that technology effectively launched depends on the existence of fringe markets which the old
technology does not serve well, or experimental users, or both. Established firms initially have little incentive to adopt
the new technology, which initially is inferior to the technology they have mastered. New firms generally cannot survive in
head-to-head conflict with established firms on the market well served by the latter. The new firms need to find a market
that keeps them alive long enough so that they can develop the new technology to a point where it is competitive on the main
market. Niche markets, or experimental users, can provide that space.

The aim of this paper is to investigate the relationship between government spending and private consumption in the UK, for which there is scarce previous empirical evidence. We disaggregate public expenditure into three categories and search for the corresponding private consumption multipliers. Our analysis is based on the estimation of a structural vector error correction model with quarterly non-interpolated data for the period 1981:1–2007:4. Initially, we estimate negative but barely significant effects on consumption of shocks to total public spending. Then, using the public spending breaking down, we find that while shocks to public wages crowd-out private consumption as predicted by neoclassical models, shocks to the non-systematic component of social spending and government purchases of goods and services generate a positive reaction, so to crowd-in private consumption. Thus, the qualitative and quantitative dimensions of fiscal multipliers on private consumption change across different public spending categories. Our findings suggest that any empirical support of competing theoretical models on the issue would benefit from a disaggregation of government expenditure, rather than focusing on the aggregate measure. 相似文献

Technology and efficiency in a panel of Italian dairy farms: an SGM restricted cost function approach 总被引:2,自引:0,他引:2
This article employs a short‐term specification of the symmetric generalised McFadden (SGM) cost function capable of accommodating quasi‐fixed factors and variable returns. Temporary equilibrium and scale economies are investigated while maintaining the consistency of the estimated model with microeconomic theory and approximation properties. It also makes use of a two‐step procedure to estimate first the technology parameters and then time‐varying efficiency at farm level. No distributional assumptions are required on efficiency as we consider a fixed effect model. A balanced panel of Italian dairy farms during the years from 1980 to 1992 serves as the case study. The results suggest a rigid productive structure during the pre‐ and post‐quota period. Moreover, Italian milk producers are found to exhibit considerable excess capacity and rather low input technical efficiency. 相似文献

In this paper we investigate the role of patents in the relationship between R&D activity, spillovers and employment at the firm level. A reduced-form labour demand equation is estimated. Our analysis is based upon a dataset consisting of 879 R&D-intensive manufacturing firms worldwide for which information was collected for the period 2002–2010. We use data from all EU R&D investment scoreboard editions issued every year until 2011 by the JRC-IPTS (scoreboards). Since the innovation output of the industrial strategy of every firm is the number of patents, the main contribution to the existing literature is to investigate also the impact of patents/R&D ratio and patents/spillovers ratio on employment level. The empirical results suggest a significant impact of R&D spillover effects on company employment although the results differ substantially according to the spillover stock, which may considerably affect policy implications. 相似文献

This paper shows that, in a repeated competitive procurement, a buyer can use the reserve price in a low-price auction as a “public”—hence nondiscriminatory—incentive device to elicit unverifiable quality. We study a model with many firms and one buyer, who is imperfectly informed on the firms' costs. When firms are ex ante identical, the provision of quality is sustained by a sufficiently high reserve price to reward firms for the quality provision and by the threat of setting a low reserve price forever, if quality is not delivered. The buyer can elicit the desired level of unverifiable quality provided her baseline valuation of the project is not too high and the net benefit from unverifiable quality is not too low. These results are robust to firms' heterogeneity in their time preferences when the punishment for a deviation is finite but sufficiently long. 相似文献
