Adoption Of Advanced Manufacturing Technology And Firm Performance In The Netherlands

This paper presents characteristics of firms that employ advanced manufacturing technology (AMT), explores the pattern of adoption of such technology, and traces the effects of adoption on the evolution of employment and productivity. The study uses linked firm-level data on production, factor inputs and on advanced manufacturing technology. It is found that the percentage of firms that employ advanced technology increases with higher labor productivity, higher export-sales ratios, and especially larger firm sire. Corrected for interactions, however, only initial size and the initial capital-labor ratio aid in predicting adoption of AMT. Conditional on adoption of AMT it is seen that intensity of advanced technology inputs decrease with firm sire and with labar productivity. Finally, firms which employed AMT in 1992 show higher average growth rates of (toral factor) productivity and employment between 1985 and 1991.     

Do minimum quality standards bite in polluting industries?

We investigate the introduction of a minimum quality standard in a vertically differentiated duopoly where production is polluting. We examine the alternative frameworks with quality-dependent fixed or variable costs, under both price and quantity competition. Under Bertrand behaviour, the introduction of a binding MQS regulation reduces product differentiation, which causes an increase in the output and pollution. Hence its adoption must rely on the increase in consumer surplus generated by the increase in output and average quality. Conversely, in the Cournot setting, a binding MQS decreases output and pollution, and its adoption is driven by the fact that the balance between these effects and the associated increase in average quality yields a welfare improvement.     

Endogenous fertility and growth in a model with old age support

Summary. This paper examines the interrelationship between capital accumulation, fertility, and growth by introducing an endogenous fertility decision into Diamond's (1965) neoclassical growth model. Under the assumptions that children provide old age support and that individuals incur a variable time cost of raising children, it investigates the potential for cyclical fluctuations in the capital-labor ratio and fertility, as well as for development trap phenomena to be observed. It is shown that when capital and labor are highly substitutable in production, there is a unique steady state equilibrium, and either damped or undamped oscillations in fertility and the capital-labor ratio may occur. However, when the elasticity of substitution between capital and labor is less than one, two steady state equilibria may exist; one with a high capital-labor ratio and a high rate of population growth, and the other with a lower capital-labor ratio as well as a lower population growth rate. The former is a saddle, while the latter may be either a source or a sink. In the latter case development traps are possible. Received: June 16, 1997; revised version: December 18, 1997     

Green operations strategy of a luxury car manufacturer

This paper investigates the strategic environmental decisions of a luxury car manufacturer. Through case study research, the investigation sheds light on why and how the company is adopting green technologies. Being pressured by different stakeholders to become greener, luxury car manufacturers carry significant opportunities for environmental improvement given the nature of their manufacturing processes and products. Because of their low-volume production, manufacturers may be able to increase output and still reduce overall emissions when compared to high-volume manufacturers. In the case study company this was found to be possible only because of new ideas brought by a change in ownership. Luxury manufacturers may also be a test-bed for the development and experimentation of green technologies as part of a strategic approach to environmental initiatives. This paper contributes to the fields of green technology adoption and operations strategy in automotive manufacturing groups.     

Measuring efficiency when competitive prices aggregate differences in product quality and risk

In perfectly competitive markets with homogenous goods, prices aggregate inputs and outputs into a money metric that allows production plans and, hence, firms to be ranked by their profitability. Standard techniques of efficiency measurement use this metric to estimate cost and profit frontiers that identify “best-practice” production, conditioned on these exogenous prices. However, when prices vary due to differences among firms in the quality of outputs and inputs and in how asymmetric informational problems are resolved, both quality and the production of information can be decision variables of the firm, and prices will have endogenous components linked to production decisions. For example, in banking, prices of financial inputs and outputs are linked to credit quality and, hence, to risk and, thus, aggregate both inputs and outputs and their risk characteristics as well as reflect how informational asymmetries in credit markets are ameliorated. This paper argues that these cases pose two serious problems for the standard techniques of efficiency measurement: (1) they underestimate inefficiency because, in conditioning on prices, they fail to account for the effects of suboptimal pricing strategies on profitability; and (2) in ignoring how production plans and pricing strategies affect market-priced risk, the standard techniques neglect the effects of different pricing strategies on the discount rate, on expected profit and, hence, on market value. Two alternative techniques that do not condition their frontiers on prices and that account for risk are described to show how they measure the efficiency of different pricing strategies as well as production plans. These two alternative models for measuring efficiency are employed to study how differences in pricing strategies affect the efficiency and market value of highest-level bank holding companies in the United States in 1994.     

Diffusion of environment-saving technological change— a petroleum refining case study

This paper attempts a theoretical model (Section I) of a dynamic relationship, brought about by environment-saving technological changes over time, between output and water pollution. The improvement in environmental quality is studied in terms of adoption of relatively environment-saving processes in petroleum refining industry. This is done (Section II) by empirically fitting the Gompertz function or the growth rates of diffusion of the processes by the use of multiple regression equations. Social desirability of substituting the relative environment-saving process is examined in terms of social benefit-cost analysis (Section III). Thereafter, (Section IV) an attempt is made to find social policy variables which could be used in order to accelerate diffusion of environment-saving processes. The analysis concludes that both “carrot” (incentives, say, in the form of accelerated depreciation allowances for purchase of environment-saving process equipment) as well as “stick” (in the form of stricter enforcement of water pollution control laws) are necessary for inducing adoption of the desired technological changes over time.     

C.E.S. production functions in the light of the Cambridge critique

The Cambridge debate of the 1960s showed conclusively that the aggregation of capital, so as to obtain a surrogate production function according to Samuelson, is not possible in general, with critical implications also for other variants of neoclassical theory. The framework for the demonstration is that of linear activity analysis.There is an individual wage curve in function of the rate of profit for each technique. If these individual wage curves were straight lines, their envelope would define a wage curve resulting from all techniques, from which a surrogate production function could be derived, but all wage curves are straight only, if there is only one industry. And if wage curves are not straight, phenomena such as reswitching show that essential neoclassical hypotheses need not hold. A recent empirical investigation by Han and Schefold has found one empirical example for reswitching and several for reverse capital deepening.A rigorous derivation of surrogate production functions thus is ruled out also on empirical grounds, but the paradoxes seem not to be as frequent as the critics once thought, so that the question arises whether approximate surrogate production functions could be derived, with individual wage curves which would be sufficiently linear to construct approximate surrogate production functions, indicating a relationship between the intensity of capital and output per head which would be sufficiently precise to work with.The paper is part of a wider investigation, in which conditions for the existence of quasi-linear wage curves and the possibility of the construction of approximate surrogate production functions are given. The emphasis here is on the special hypotheses needed to obtain C.E.S. production functions.     

PAF—A new probabilistic, computer-based technique for technology forecasting

The ultimate goal of all technology forecasting is to assist managers and planners in the decision-making process. The employment of computer techniques may increase the utility of a forecast because it permits the rapid incorporation of vast amounts of data into the projection process. On the other hand, the value of computer-based forecasts depends on the compatibility of output information with other elements of the planning system and on the confidence of the users in both the input data employed and the manner in which those data are processed. For the last three years researchers at The University of Texas at Austin have been developing a new computer-based forecasting technique called PAF (Partitive Analytical Forecasting). This technique is based on the development of logic networks which simulate the evolution and maturation of advanced technology. PAF utilized a specially developed interview technique for gathering input data and a special time-sequenced computer simulation for data processing. The final results of PAF analysis are a series of probability-associated forecasts of the time necessary for the development of a given technology and of the related costs of development. Forecasts are made for specified sets of assumptions and management strategies, and alterations of either input data or program structure are easily made. Early indications are that PAF will prove to be a valuable management tool, particularly for long-term, complex, high-risk technical programs. In this article the basic methodology of the PAF technique is discussed along with the major PAF project to date, a projection of fusion power development. Recent improvements, including the addition of optimization routines, are also briefly discussed.

Factor Endowment,the Choice of Technology,and the Volume of Trade

Abstract

This paper studies impacts of factor endowment on international trade in a general equilibrium model in which firms choose their technologies endogenously. Although countries only differ in factor endowment ex ante, countries may also differ in their chosen technologies. If industries choose different capital-labor intensities in equilibrium, the Heckscher–Ohlin theorem, factor price equalization theorem, the Rybczynski theorem, and the Stolper–Samuelson theorem hold. If industries choose the same capital-labor intensity in equilibrium, the volume of trade is zero. None of the four theorems applies.     

Quantity-cum-quality contests

Quality and quantity are very common features of production processes. People care about these two features and they tend to be connected. I consider a contest in which the quantity and quality of output are rewarded. The output in the quality contest plays a dual role. It counts in the quality contest but it is also converted into quantity-equivalent output to obtain total output in the quantity contest. This latter feature implies that the two contests are interlinked. I find that when the unit cost of producing quality is sufficiently high, then treating quality and quantity as the same has a disincentive effect on the production of quality. In contrast, when the unit cost of producing quality is sufficiently low, treating quality and quantity as the same has no disincentive effect on the production of quality. I also find an equilibrium in which no one exerts effort in the quantity contest. When there is a binding budget constraint on effort, I find that effort in the quantity contest is smaller relative to the unconstrained case but effort in the quality contest may remain unchanged.     

The economic implications of learning-by-doing for population size and growth

This paper criticizes Arrow's research on learning-by-doing. The authors use a model like Arrow's to conclude that population growth--and, even more important, population size--may have positive effects on economic growth through positive effects on the rate of technical progress, on reasonable assumptions about the likely capital-output ratios with different demographic structures, but negative effects with other capital-output ratio difference. In a comparison of 2 worlds that have different population sizes, but that are otherwise alike including their capital-labor ratios and the initial per worker outputs, the larger world will come to have higher per worker output because of learning-by-doing. This conclusion is unlike the conclusion implicit in Arrow's model of learning-by-doing because Arrow looked at steady-state rates of growth rather than changes in the level of income from the starting point. Arrow's analysis also is confused by using the capital stock rather than cumulative output as the measure of experience, though output is the variable used in the empirical analyses that are the basis of this line of work.     

Wages and profits: A comment

Clark's (1979) model for the levels of aggregate wages and profits is respecified and reestimated using modern econometric techniques. One result is a more efficient estimate of the capital-labor substitution elasticity. In addition, the presence of very strong positive autocorrelation in one of the equations sheds doubt on Clark's assertion that a model for the levels of these variables is more appropriate than a model for their year-to-year changes.     

DOES SCIENTIFIC AND TECHNICAL RESEARCH REDUCE MACROECONOMIC VOLATILITY?

This paper explores whether conducting scientific and technical (S&T) research reduces the volatility of output growth. The paper finds robust evidence that output volatility is significantly lowered by a country's production of S&T publications. The results show that the effect of S&T publications on output volatility is particularly strong in middle‐income, OECD and other high‐income countries. However, for East‐Asian, low‐income and sub‐Saharan African countries the effect is either weak or absent. These results provide strong evidence that not only OECD and other high‐income countries are actively engaged in S&T research, emerging developing countries are also conducting S&T research, which is effective in reducing output volatility. The results are robust to adding a host of control variables, various subsamples and different estimation techniques.     

Wages and profits

Wages and profits must be regarded as simultaneously determined—profits must not be regarded as a residual. In the short period both are determined by current demand, profits fluctuating much more strongly than wages. More important is the long-period factor, which depends upon capital-labor substitution elasticity.     

The Impact Of Technology Adoption On Firm Productivity *

In this paper an attempt is made to theoretically and empirically explore the impact of technology adoption on firm output and productivity. The theory is based upon a modified Cobb Douglas production function with capital, labour and technology adoption as arguments. Three versions of the model with varying degrees of endogeneity are developed and then tested upon a data set relating to the adoption of five different process technologies by 217 firms in the UK engineering industry over the period 1981–1990. All the results indicate that technology adoption has a positive impact on output and productivity.     

Exploring Links Between Innovation and Diffusion: Adoption of NO<Subscript>X</Subscript> Control Technologies at US Coal-fired Power Plants

While many studies have looked at innovation and adoption of technologies separately, the two processes are linked. Advances (and expected advances) in a single technology should affect both its adoption rate and the adoption of alternative technologies. This paper combines plant-level data on US coal-fired electric power plants with patent data pertaining to NO_X pollution control techniques to study this link. As in other studies of environmental technologies, the effect of other explanatory variables is dominated by the effect of environmental regulations, demonstrating that the mere presence of environmental technologies is not enough to encourage its usage. Nonetheless, I do find that technological advances are important for the adoption of existing combustion modification technologies. However, these advances are less important for the adoption of newer post-combustion control techniques, which are adopted only when needed to comply with the strictest emission limits.     

The Transition to Market Economies in an Endogenous Growth Model with Altruistic Agents

This paper considers an endogenous transition from a self-sufficient traditional economy to a market economy and its consequences on fertility and growth. The transition can occur if private intergenerational transfers are unable to secure old-age consumption as adequately as savings on capital markets; otherwise individuals stay in the traditional economy unless the mass-production technology in the market economy is sufficiently more advanced than individually accessible technologies. Markets emerge only if per capita output exceeds a certain level given a fixed cost of forming markets. The transition reduces fertility and promotes growth under plausible restrictions.

Fiscal and monetary effects on environmental quality,growth, and welfare

This paper examines the effect of fiscal and monetary policies on economic growth, inflation, environmental quality, and welfare. To this end, the horizontal-R&D growth model is extended to include pollution generated in the intermediate-goods production, and the demand for money through cash-in-advance (CIA) constraints on intermediate-goods production and R&D investment. Fiscal policy embodied in the taxation of pollution decreases output, profits, inflation, and wages in the intermediate-goods sector, reallocating labor to R&D that is the engine of economic growth. As it reduces pollution, it increases welfare if there are strong preferences for a clean environment. In turn, since the inflation rate is an increasing function of the nominal interest rate, the effects of changes in this monetary policy variable extend to the effects of changes in the inflation rate. An increase in the nominal interest rate penalizes employment, wages and output in the R&D sector relatively more if the respective CIA constraint is more demanding and thus economic growth decreases. As it also reduces pollution since decreases intermediate-goods production, it increases welfare if the preferences for a clean environment are strong enough.     

Variable output elasticities and technique-specific technical progress: A method of measurement

The possibility of accounting for technique specific technical progress in an econometric production function is raised. In addition the validity of the assumption of constant output elasticities over input combinations is questionned and tested using aggregate U.S. industrial data. There appears to be considerable variation in output elasticities over different techniques of production.
