All seed firms in six EU countries were surveyed in May 1999 to determine how seed development budgets were distributed across three crop development technologies and the effects of the type of technology in use on employment, sales and exports. The results indicate that an evaluation of the economic consequences of an emergent technology such as genetic engineering should both consider the effect of competitive alternative technologies and survey all firms within the sector, rather than focusing on a subset of high technology firms. Only about 10% of the combined 1999 research budget of European seed firms was spent on genetic engineering, although this should increase to about 15% by 2002. Alternative technologies to develop new plant varieties, such as conventional plant breeding and conventional breeding combined with techniques that were developed for genetic engineering, are considerably more important economically. In fact, there is no difference in expected employment and sales per development employee by the type of technology in use, while export rates are highest among firms that combine conventional plant breeding with advanced techniques.  相似文献

R&D spillovers and productivity: Evidence from U.S. manufacturing microdata   总被引:1,自引:0,他引:1  
This paper deals with the estimation of the impact of technology spillovers on productivity at the firm level. Panel data for American manufacturing firms on sales, physical capital inputs, employment and R&D investments are linked to R&D data by industry. The latter data are used to construct four different sets of `indirect' R&D stocks, representing technology obtained through spillovers. The differences between two distinct kinds of spillovers are stressed. Cointegration analysis is introduced into production function estimation. Spillovers are found to have significant positive effects on productivity, although their magnitudes differ between high-tech, medium-tech and low-tech firms.

We apply a panel vector autoregression model to a firm-level longitudinal database to observe the co-evolution of sales growth, employment growth, profits growth and the growth of research and development (R&;D) expenditure. Contrary to expectations, profit growth seems to have little detectable association with subsequent R&;D investment. Instead, firms appear to increase their total R&;D expenditure following growth in sales and employment. In a sense, firms behave ‘as if’ they aim for a roughly constant ratio of R&;D to employment (or sales). We observe heterogeneous effects for growing or shrinking firms, however, suggesting that firms are less willing to reduce their R&;D levels following a negative growth shock than they are willing to increase R&;D after a positive shock.  相似文献

Among the various questions raised by theoretical studies on self-managed firms, the author considers two key issues dealing with job rigidity in these enterprises and with their ability to get external financing: should the employment of non-member workers in these firms be encouraged or not? Should the external financing of these firms be deregulated or not? These two questions are related to an important part of the literature on self-managed firms which is dedicated to their so-called perverse behaviours and to the stability of this type of production organization. The theoretical models help to understand the difficulties experienced by this type of organization and to see how and why the constraints on employment of non-member workers and on the external financing possibilities can have positive effects on self-managed firms. Among these results, those coming from the analysis of the choice of structures and production techniques help to understand the development of self-managed firms in industries which require high level production techniques and high human skills.  相似文献

This pape criticizes the concept of 'technological discontinuities'. It argues that the concept is misleading when the skills and knowledge of an indusry are composed of multiple rather than single core technologies. In cases such as the use of genetic engineering as the basis of production in pharmaceuticals, both existing pharmaceutical firms and new biotech firms integrate the new techniques into existing indusrial practice. The radical tecnology both enhances and destroys existing knowledge; the key to survival has been integration. Both existing and new firms have had the possibility of integrating multiple core technologies, but firms have been able to do so in different ways. Some existing firms could jump over to the radically new 'technological trajectory', by combining their creation of new competencies through in-house R&D with their access to novelty through relations with external agents in systems of innovation.  相似文献

The impact of capital accumulation on job creation is an important and interesting issue in economic development. This model provides a general-equilibrium framework for studying technology choice with unemployment in a developing economy based on micro-foundations. Unemployment in the urban sector results from the existence of efficiency wages. Manufacturing firms engage in oligopolistic competition and choose technologies to maximise profits. A more advanced technology uses more capital and less labour. In the steady state, an increase in the amount of capital induces firms to choose more advanced technologies and the wage rate increases. While a higher capital stock always induces firms to choose more advanced technologies, urban unemployment rate may decrease and agricultural sector employment may increase.  相似文献

Abstract We use plant‐level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. We develop a model to generate predictions about how the intensity of international sourcing of materials depends on the availability of services and firm characteristics. These predictions are supported by the data. Greater availability of services across regions, industries, and time increases firms’ foreign sourcing of materials relative to sales. The impact of services differs by firm type. National firms’ sourcing responds to changes in regional service conditions, whereas multinationals tend to be less affected.  相似文献

This paper studies a general equilibrium model of rural-urban migration in which manufacturing firms engage in oligopolistic competition and choose increasing returns technologies to maximize profits. Urban residents incur commuting costs to work in the Central Business District. Surprisingly a change in the size of the population or an increase in the exogenously given wage rate will not affect a manufacturing firm’s choice of technology. This helps to explain why firms in developing countries may not adopt labor intensive technologies even under abundant labor supply. An increase in the number of manufacturing firms increases both the employment rate and the level of employment in the manufacturing sector. However, manufacturing firms choose less advanced technologies. Capital accumulation leads manufacturing firms to choose more advanced technologies, but may not increase employment in the manufacturing sector.  相似文献

In this study, we use a unique rich newly built data set for German manufacturing enterprises to investigate the relationship between product diversification and the stability of sales and employment. We find that contrary to portfolio theoretic considerations, more diversified firms exhibit a higher variability of sales and employment. However, the effects are negligibly small from an economics point of view.  相似文献

Targeted genetic modification (TagMo) technologies are being used for new approaches to genetic engineering often called ‘genome editing’. These approaches are in the early stages of development, and basic understandings of what TagMo is, of its likely future, and how it should be governed are still being established. In order to inform these discussions and increase their transparency, we map the scientific landscape of TagMo using advances in tech mining and bibliometrics and in consultation with experts in the field. We assess the sub-topics and disciplines associated with TagMo research, and the actors, institutions, and nations involved, while making observations about the funding of research and the collaborative patterns among actors. The technology assessment approach used in this article has important implications for anticipatory governance of TagMo plant products. It is designed to help scientists, managers, and policy-makers understand trends in TagMo technological development in order to prepare for future governance.  相似文献

Technological Activity and Employment in a Panel of UK Firms   总被引:2,自引:0,他引:2  
We investigate the relationship between technological activity, proxied by R&D, patents, and trade marks, and employment for a panel of British production firms from 1987 to 1994. We modify standard derived demand for labour to include technology variables. We find employment is fostered by R&D expenditure and UK patent publications, ceteris paribus on factor costs and current sales. The employment impact of R&D is bigger in high technology sectors, but employment increase from UK patenting activity is bigger in mature technology sectors. In further analysis of persistent differences (the estimated firm fixed effects) UK trade marks and US patents are also positively associated with employment.  相似文献

While financial or trade integration between countries may increase the size of the market and aid the adoption of more advanced technologies, will it also increase the level of urban unemployment for a developing country? In this model, there is unemployment in the urban sector. Manufacturing firms engage in oligopolistic competition and choose increasing returns technologies to maximize profits. Financial firms provide capital to manufacturing firms and they also engage in oligopolistic competition. We show that an increase in the wage rate in the manufacturing sector changes neither the level of technology nor the level of employment in the manufacturing sector. While financial or trade integration between developing countries leads manufacturing firms to adopt more advanced technologies, the level and rate of employment in the manufacturing sector will not deteriorate.  相似文献

The Social Value of Biodiversity for R&D   总被引:1,自引:0,他引:1  
The value of genetic resources for use in research and development (R&D)activities has been the subject of a literature modelling the activity as onewhere individual firms engage in optimal search. Here we develop a moregeneralised framework in which genetic resources are used in R&D at thebase of an industry that addresses recurring problems of resistance, as inthe pharmaceutical or plant breeding industries. The R&D process is onein which firms are engaging in a continuing contest of innovation againsta background of both creative destruction (Schumpeterian competition) andadaptive destruction (natural selection and adaptation). This frameworkdemonstrates that the search model is conceptually inadequate because itfails to incorporate the important dynamic characteristics of biologicalphenomena. We then demonstrate the important differences between firm-based valuation of genetic resources and the social value of geneticresources for use in this contest of innovation. There are six externalitiesin private patent-based genetic resource valuation, and five of theseindicate that private valuations will under-estimate social values.  相似文献

This paper develops a model of trade that features heterogeneous firms, technology choice and different types of skilled labor in a general equilibrium framework to explain within‐industry increase in the relative demand for skilled workers. Its main contribution is to investigate the impact of firms' export and technology choice decisions on skill upgrading. Only firms in the upper range of the productivity distribution produce for the foreign market using high‐technology. Since this technology is skilled‐biased, exporters that resort to modern technologies are more skill intensive. Empirical evidence is also provided to support the model's main predictions using plant‐level panel data from Chile's manufacturing sector (1990–1999).  相似文献

This paper examines the determinants of the profitability of short-stay accommodation providers in Tasmania, utilising a survey conducted from July 2007 to June 2008. The survey provides insight into a time when some firms had adopted the 'new' information technologies to make sales while others continued with traditional methods. We find the use of online sales is associated with higher profit. Further profit is higher during summer (high season), for firms with a high star rating and for firms who make a larger proportion of their sales directly to customers, and lower when owner operators are motivated by lifestyle considerations.  相似文献

The impact of financial constraints on firm survival and growth   总被引:1,自引:0,他引:1  
We propose a new approach for identifying and measuring the degree of financial constraint faced by firms and use it to investigate the effect of financial constraints on firm survival and development. Using panel data on French manufacturing firms over the 1996–2004 period, we find that (1) financial constraints significantly increase the probability of exiting the market, (2) access to external financial resources has a positive effect on the growth of firms in terms of sales, capital stock and employment, (3) financial constraints are positively related with productivity growth in the short-run. We interpret this last result as the sign that constrained firms need to cut costs in order to generate the resources they cannot raise on financial markets.  相似文献

Wage and Technology Dispersion   总被引:4,自引:0,他引:4  
This paper explains why firms with identical opportunities may use different technologies and offer different wages. Our key assumption is that workers must engage in costly search in order to gather information about jobs (Stigler (1961)). In equilibrium, some firms adopt high fixed cost, high productivity technologies, offer high wages, and fill job openings quickly. Other firms adopt less capital-intensive technologies and offer low wages, hiring mostly uninformed workers. In equilibrium, the amount of wage dispersion leaves workers indifferent about whether to gather information, and the fraction of informed workers leaves firms indifferent about their wage and technology choice. We show that worker search, which would appear to be a rent-seeking activity in partial equilibrium, may be efficiency-enhancing in general equilibrium.  相似文献

The objective of this research is to evaluate the effect of the economic recession on the performance of firms located in science or technological parks. Compared to off-park firms, we propose that under an economic crisis park benefits are more noticeable, since firms located inside parks have less resource restraints and access to external sources of information and knowledge. Moreover, we observe that as firms invest on internal R&D, they tend to reinforce these park benefits. Empirical evidence gathered data on employment and sales from 2007 to 2012 for the group of firms which participated in the Spanish Technological Innovation Panel. The results confirm the positive role played by science and technology park locations under economic downturn environments, especially when firms investing in internal R&D.  相似文献
