Growth,unemployment and public capital

Abstract. Existing literature has studied the growth effects of fiscal policy in models with full-employment. The aim of this paper is to study these growth effects in an endogenous growth model with unemployment and compare them with the effects obtained when there is full-employment. To this end, we assume that unemployment arises due to the existence of unions. We also assume that the government finances, by means of income taxes, both public capital and an unemployment benefit. Public capital increases total factor productivity and modifies the elasticity of the labor demand. We show that the effects of fiscal policy on both employment and growth crucially depend on the relation between this elasticity and public capital.

Veblen and the New Growth Theory: Community as the Source of Capital's Productivity

A century ago Thorstein Veblen argued that knowledge, which is produced and possessed by the community as a whole, is the foundation on which the productivity of "capital" rests. Orthodox economists chose to ignore Veblen and instead accepted John Bates Clark's definition of capital and the marginal productivity theory that goes with it. Recently, however, mainstream economists working on the "New Growth Theory" have rejected Clark's approach and have redefined capital so as to emphasize the importance of knowledge as well as its social character. Nevertheless, they still have an important lesson to learn from Veblen about growth, namely that technological development is nothing less than a process of cultural transformation.     

Productivity Growth And Market Structure In Telecommunications

This study examines sources of telecommunications sector productivity growth. Total factor productivity (TFP) growth is calculated using the Malmquist productivity index for a sample of 74 countries for the period 1991 through 1995. An econometric model is estimated which relates TFP growth to output growth, network digitisation, telecommunications development, output-mix, the business cycle and market structure. Model estimates suggest that higher digitisation rates dampen TFP growth in the short run, and cross-subsidisation of services creates inefficiency. However, developing countries can increase TFP growth through catch up, and increased privatisation and competition are conducive to productivity growth.     

Inter-Firm Technological Cooperation: Effects Of Absorptive Capacity,Firm-Size And Specialization

This paper aims to add evidence on the role played by firms' technological competencies in the determination of their intensity of cooperation with other firms. Using a database composed by patents jointly filcd by two or more firms in the European Patent Office, the paper confronts the hypotheses of complementary or substitutive character of technological cooperation in relation to intra-mural R&D. The results suggest that more technologically and productive specialized firms are more likely to cooperate and find no support for the hypothesis that greater level of R&D expenditure will induce greater reliance on technological cooperation. It is also suggested that firms cooperate with partners that hold cotilplenientary competencies.

Gross Investment And Technological Change

The impact of technological change upon gross investment has been relatively ignored. Building upon the foundations of the analysis of technological diffusion, an empirical model of gross investment is constructed that takes due account of technological change. This model is then tested upon a panel data set covering 185 UK firms over the period from 1984 to 1992. The results support the hypothesis that there are significant relationships of the expected signs between firm level gross investment, indicators of technological opportunity; the price of the capital goods that embody new technology, and firm and industry characteristics. There is also evidence of lagged adjustment effects in the investment process.     

New Technology-Based Firms In Sweden - A Study Of Their Direct Impact On Industrial Renewal

The purpose of this paper is to analyse some of the ways in which new tcchnology-bascd firms (NTBFs), started after 1975, have contributed to the process of industrial renewal in Sweden. For this purpose, we have developed a novel way of operationalizing the concept of NTBFs and of identifying the population of such companies in Sweden. The method relies heavily on unique data on the educational background of the firm's staff. We found that NTBFs constitute a relatively small but growing phenomenon in Sweden. Although small in magnitude, the firms have contributed to industrial renewal by increasing the knowledge-intensity and science base of Swedish industry and industry-related services. They have also contributed somewhat to the redirection of the knowledge base in Sweden in favour of skills which are central to the innovation process in growth sectors, primarily computer science skills.     

Establishment Level Earnings,Technology And The Growth Of Inequality: Evidence From Britain

It is often argued that technical change is responsible for the increase in wage inequality in Britain and the United States in the 1980s and 1990s. In this paper we examine this argument using data from individuals and establishments. It is found that the presence of micro-electronic technologies in workplaces is associated with higher earnings, especially for skilled workers. Decompositions suggest that technical change could have been a cause of the increase in skills premium for highly skilled workers. Nevertheless, our view is that the correlation between wages and plant-level technology is mainly driven by the effect of high wages on the propensity to introduce new technologies rather than vice versa. This view is supported by simultaneous models of the wage-technology relationship.

知识产权保护与经济水平对技术创新的作用机制研究

基于2012—2017年我国省级面板数据,将区域层面的工业企业创新过程划分为技术研发和技术成果转化两阶段,以地区规模以上工业企业为研究对象,采用混合OLS回归、固定效应模型和系统广义矩估计方法检验知识产权保护与经济水平对工业企业两阶段创新的作用。结果发现：①知识产权保护和经济水平对区域工业企业技术研发和技术成果转化两阶段均有显著促进作用;②在工业企业技术研发和技术成果转化两阶段均存在知识产权保护与经济水平的交互作用,这一交互作用削弱了两者对工业企业技术创新过程的促进作用;③知识产权保护、经济水平对工业企业技术研发阶段的影响强度大于技术成果转化阶段;④基于我国各地区当前经济水平,大部分区域仍须加强知识产权保护以进一步促进区域工业企业技术创新。     

转型期知识产权保护制度的增长效应研究

知识产权保护制度是发展中国家能否克服短期技术困境、促进经济长期增长的关键因素。本文从宏观层面研究我国知识产权保护制度对经济增长的影响机制,主要贡献在于:首先通过构建知识产权保护指数,实际测算1985—2010年中国的知识产权保护程度。其次通过构建"知识—生产"两部门理论模型,分析知识产权对经济增长的影响机制。最后基于中国转型期经验数据,运用动态建模方法实证研究我国知识产权制度对经济增长的影响。研究表明,对于处于转型期的中国而言,短期内较弱的知识产权保护程度有利于经济增长,而较强的知识产权保护程度则有碍于经济增长;在长期均衡的状态下,较强的知识产权保护程度确实可以促进经济增长。     

技术创新与我国反垄断立法

从技术经济和产业组织的角度观察,企业技术创新除了高知识性、高不确定性和高沉没成本外,溢出性是其重要特征之一.本文提出在我国的反垄断立法中应采纳动态竞争而非静态竞争的思想;对与技术创新相关的企业合并采取创新市场分析而非产品市场分析,从创新要素投入而非创新产出的角度评价;正确处理保护知识产权和反垄断的均衡关系,为我国企业技术创新营造一个良好的市场经济环境.     

Computers And Growth

The purpose of this paper is to describe the impact of investment in computers on the growth of the U.S. economy. The economic literature on computers is relatively rich in information on the decline in computer prices and the growth of computer investment. Constant quality price indices for computers have been included in the U.S. National Income and Product Accounts (NIPA) since 1986. These indices employ state of the art methodology to capture the rapid evolution of computer technology.

While the annual inflation rate for overall investment has been 3.66 percent for the period 1958 to 1992, computer prices have declined by 19.13 percent per year! Similarly, overall investment grew at 3.82 percent, while investment in computers increased at an astounding 44.34 percent! These familiar facts describe growth in the output of computers. The objective of this paper is to complete the picture by analyzing the growth of computer services as inputs.

In a pioneering paper Bresnahan (1986) has focused on pecuniary externalities arising from the rapid decline in computer prices. Griliches (1992, 1994) has emphasized the distinction between pecuniary and nonpecuniary externalities in the impact of computer investment on growth. This paper is limited to pecuniary externalities or the impact of reductions in computer prices on the substitution of computer services for other inputs. As Griliches (1992) points out, this is an essential first step in identifying nonpecuniary externalities or ‘spill-overs’ through the impact of a decline in computer prices on productivity growth. ^{* *}Brynjolfsson (1993) has proveded a detailed survey of studies of nonpecuniary externalities or ‘spill overs’. Recent studies include those of Brynjolfsson and Hitt (1994a, 1994b) and Lichtenberg (1993).

In two important papers Stephen D. Oliner (1993, 1994) has introduced a model of computer technology that greatly facilitates the measurement of computer services as inputs. In this paper we estimate computer stocks and flows of computer services for all forms of computer investment included in NIPA. We construct estimates of computer services parallel to NIPA data on computer investment by combining these data with information on computer inventories. For example, the International Data Corporation (IDC) Census of Computer Processors includes an annual inventory of processors in the U.S.

In Section 1 we present data on investment in computers and constant quality price indices from NIPA. These data incorporate important innovations in modeling computer technology stemming from a joint study by IBM and the Bureau of Economic Analysis (BEA) completed in 1985. This study utilized a ‘hedonic’ methodology for constructing an econometric model of computer prices that accurately reflects rapid changes in computer technology. This methodology generates an index of computer prices that holds the quality of computers constant.

In Section 2 we present the model of computer services originated by Oliner (1993,1994). This differs in important respects from the model of capital services used in the previous studies of U.S. economic growth surveyed by Jorgenson (1989,1990). The model employed in previous studies is based on the decline in productive capacity with the chronological age of a capital good. Oliner assumes that computers maintain their productive capacity until they are retired. Decline in productive capacity occurs only through removal of used computers from the inventory through retirement.

In Section 3 we construct estimates of stocks of computers that incorporate IDC data on computer inventories and derive the implied flow of computer services. While output of computer investments has grown very rapidly, the input of computer services has grown even faster. The price of these services has declined at 23.22 percent per year over the period 1958 to 1992, while the input of these services has grown at 52.82 percent! This is prima facie evidence of an important role for computer price declines as a source of pecuniary externalities.

In Section 4 we combine computer services with the services of other types of capital to produce a measure of capital input into the U.S. economy. We link this with labor input to obtain the contributions of both inputs to U.S. economic growth, arriving at the growth of productivity as a residual. We find that the contribution of computer services to input into the U.S. economy is far more important than the contribution of computer investments to output. This is a significant step toward resolution of the Solow paradox: ‘We see computers everywhere except in the productivity statistics. ^{* *}Robert M. Solow, quoted by Brynjolfsson (1993). Declines in computer prices generate very sizable pecuniary externalities through the substitution of computer services for other inputs. By contrast Solow focuses on nonpecuniary externalities that would appear as productivity growth.

In Section 5 we conclude that information on inventories of computers is critical in quantifying the role of computer services as inputs. The constant quality price indices for computers incorporated into NIPA are also essential. A price index for computers that reflects only general trends in inflation would result in a highly distorted perspective on the growth of GDP and capital services, especially during the past decade. To capture the contribution of all forms of investment to U.S. economic growth, similar price indices should be included in NIPA for capital goods with rapidly evolving technologies, as proposed by Gordon (1990).

The long term goal should be a unified system of income. product, and wealth accounts, like that proposed by Laurits Christensen and Jorgenson (1973) and Jorgenson (1980). This incorporates capital stocks, capital services, and their prices. Achieving this goal will necessitate much greater elaboration of the accounting system described in Section 3. These accounts would incorporate data on prices and quantities of investment, stocks of assets, and capital services for all forms of capital employed in the U.S. economy.     

Technological Change Bias In The U.S. Investor-Owned Electric Utility Industry Following Potential Deregulation

This paper estimates regulated and poientially deregulated costs of production for a multiproduct electric utility industry. The empirical evidence suggests technological regression with respect to costs in both regulated and deregulated environments. Analysis of factor cost shares indicates that technological change in a deregulated environment is expected to be less apital saving than technological change in the regulated environment. In addition, this study finds that overall diseconomies of scale may be nduced over time and to a greater extentunder deregulation than under regulation. Also, cost complementarities may be enhancedover time, but to a lesser extent under deregulation. Hence. tendencies toward natural monop oly may be increased or decreased by deregulation, and advancing deregulation may or may not be an appropriate policy.     

Renegotiation in agency contracts, menus vs. simple contracts

The literature on contracts has shown that renegotiation in agency relationships generates efficiency losses when the principal leads the renegotiation. We show that contractual incompleteness may reduce such efficiency loss. This provides an explanation to the widespread use of simple contracts. We further point at the limited liability of the agent as a source of inefficiency when he leads the renegotiation; this latter result tempers the irrelevancy of contractual incompleteness demonstrated earlier in the literature.

Firm Organization,Technology And Performance: An Empirical Study ∗

The purpose of the study is to characterize different styles of work organization in French firms and their current changes and to link them to the use of specific technologies and to firms performance. The data which are used arc of two kinds: a labor force survey (1 470 blue collar) and a business survey (7 089 firms). We show that two main variables create differences among firms' organization devices: the intensity of communication within the workshop and the level of autonomy of workers (facing technological and hierarchical constraints). The use of advanced technologies and the skill of the labor force are positively linked to both organizational variables. Therefore. ‘Communicating organization’ and organizational innovation seem to aim at creating conditions for individual and collective learning on new technologies. They also enhance the ability of the firm to adapt to changing market conditions through technological innovation and inventory reduction, These views are supported by econometric estimation.

Network Production,Efficiency And Technological Options: Toward A New Dynamic Theory Of Telecommunications ‡

In this work we propose a new model for the analysis of telecommunications (Tlc) networks production. This represents an extension of the fund-flow model by Georgescou-Roegen originally applied to the manufacture and agriculture sectors. The adopted framework enables us to describe the functioning of a Tlc network - and the technique underlying the different types of Tlc traffic - by means of a system of multi-production where the production time profile has been clearly defined. One of the most innovative elements of our analysis is the ability to analytically represent the qualitative features of technological options. It also signals new productive options connected to new Tlc services and the introduction of new network facilities. In this way we hope to both further a theoretical understanding of the technological dynamics of the Tlc sector, and provide guidance as to the strategic choices of the economic actors involved.     

Unemployment duration and workers' wage aspirations in Spain

This paper examines unemployed workers' declared willingness to work for wages lower than the one adequate for their qualification. We analyze which personal and economic characteristics determine this willingness and how it changes along the individuals' unemployment spells. The main results are: (i) Young workers, less educated and those living in regions or times of high unemployment are more willing to accept reduced wages while married women with a working husband are much less willing to do so; (ii) Once the individual fixed effect is controlled for, the willingness to work for reduced wages increases with the duration of unemployment; (iii) Not having access to unemployment benefits increases the probability that initially unwilling workers become willing to accept reduced wages.
