An input-output approach to forecasting gross domestic output and employment intensities by sectors

The purpose of this paper is to integrate two commonly known input-output models of Leontief and Stone for employment analysis. Although assumptions of Leontief model are somewhat different from Stone's model, the empirical analysis can be conducted ignoring the difference between competitive and noncompetitive imports in the initial stage. The Leontief model is used to make predictions of gross domestic output on the basis of predicted imports and final demand by sectors. The predicted output is used to derive employment by sectors for a target year and this in turn is used in Stone's input-output framework for the analysis of total labour intensity by sectors. The approach on the estimates of labour intensity by sectors is illustrated using Japan's input-output data.     

The future employment impacts of industrial robots : An input-output approach

An input-output framework is employed to estimate the indirect as well as direct effects of industrial robots on employment by industry sector and occupation. Net employment impacts are defined as the combined effects of the production and the use of industrial robots under the assumption that the demand for goods produced with this new technology is unaffected. These employment effects are estimated as the difference between a base economy (1977) and the same economy with an additional robot-producing sector and given (1990) stocks of robots installed in manufacturing industries. Six scenarios are defined by alternative levels of Robotics sector output and installed robots. The results show that job displacement is 4.5 to 6.2 times greater than job creation, that under the most extreme scenario the aggregate net job loss is 718,000, about 0.7 percent of total 1984 employment, and that the growth occupations (engineers) are highly skilled and white-collar while the declining occupations (welders, painters, machine operators, laborers) are relatively low skilled and blue-collar.     

A differential approach to input-output analysis

The differential production theory approach is applied to input-output analysis under the assumption that each industrial sector behaves as a homothetic cost-minimizing firm. This yields substitution terms which take a simple form under input independence.     

Price dynamics in an input-output model: An alternative approach

The suggested approach is developed, on the basis of firms' markup behaviour, in terms of current prices making value coefficients change as the effects of the initial price rise spread through the economy.     

Income growth and atmospheric pollution in Spain: An input-output approach

The relationships between economic growth and environmental pressures are complex. Since the early nineties, the debate on these relationships has been strongly influenced by the Environmental Kuznets Curve hypothesis, which states that during the first stage of economic development environmental pressures increase as per capita income increases, but once a critical turning point has been reached these pressures diminish as income levels continue to increase. However, to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in Spain. The aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in Spain. In order to obtain empirical outcomes for this analysis, we adopt an input-output approach and use NAMEA data for the nine pollutants. First, we undertake a structural decomposition analysis for the period 1995-2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions. And second, we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure.     

Trade,structure and linkages in Costa Rica: An input-output approach

Input-output tables for Costa Rica are used first to assess the country's trade performance; it is argued that trade with the rest of Central America has produced a Costa Rican comparative advantage in consumer durables. The paper then uses the input–output tables to examine the economy's structure, which is shown to be block triangular. Finally, measures of linkages are derived from the tables and a critique of the growth-inducing linkage mechanism is presented.     

A new approach to modeling waste in physical input-output analysis

It is important to treat waste properly in physical input-output analysis and a series of publications discussed this topic in this journal recently. In this paper, we propose a new approach to deal with physical input-output table (PIOT) measured in a single mass unit, by which the structure of PIOT need not be changed. The new approach yields consistent and reasonable results. It not only is simpler than the existing approaches but also can reflect the physical reality of economic systems. We first discuss and clarify the concept of different kinds of inputs and outputs of economic systems. We then present the details of the new approach. During the process we define a new multiplier, which builds a bridge between the total input and the final demand in PIOT, just like the traditional Leontief inverse in MIOT. We select the three-sector PIOT for Germany 1990 as a case study to show the validity of the new approach. Finally, we prove the equivalence between the new approach, Suh's approach and Dietzenbacher's approach and the equivalence of non-waste part and waste part multiplier of the new approach and Dietzenbacher's approach.     

Regional economic development and environmental repercussions: An environmental input-output approach

This study attempts to examine issues related to the existing adverse relationship between regional economic development and natural environment protection. For doing so, a regional environmental input-output model for the region of central Macedonia in northern Greece is constructed in order to quantify the direct and indirect undesirable negative effects of the production process in the natural environment. The results suggest that there is a considerable trade-off between economic development and environmental deterioration which should be taken into account when policy decisions are made. This paper benefitted from comments by the participants of the Forty-Seventh International Atlantic Economic Conference, Vienna, Austria, March 16–23, 1999.     

Foreign-exchange distribution in Yugoslavia's new planning system: An input-output approach

Under the new planning system in Yugoslavia, the foreign-exchange earnings of the final exporter should be shared by all the producing units that contributed to the production of the exported goods or services. A method of calculating the contributions of the various producing sectors to a country's exports is developed. This method makes use of the value-added/gross-output ratios of individual sectors and the Leontief inverse matrix. The analysis is extended to an examination of the balance-of-trade effects of exports.     

An environmental assessment of future production-related technological change: 1970–2000 (An input-output approach)

This paper develops a technique, or model, to systematically assess the environmental impact of specific technological changes forecast to occur over this and the next two decades. The core of the model is a dynamic technical coefficient matrix of a large input-output model. The technological change considered is that which affects the coefficients of this matrix and thus the distribution of material inputs over time into the various sectors of the U.S. economy. An environmental assessment of this production-related technological change is achieved through a submodel that registers production residuals on an industry basis for 14 waste categories.     

Sectoral employment effects of trade and productivity in Europe

The impact of trade and technology in the European case is assessed. A framework is developed which incorporates employment effects of (i) export expansion (ii) import competition and (iii) labour-saving productivity improvements. In this context, evidence is found for the hypothesis that international trade induces adjustments in technology.     

Human capital,employment protection and growth in Europe

Using data for a large sample of manufacturing and service sectors in 14 EU countries, this paper shows that the value added and TFP growth rate differential between high and low human capital intensive industries is greater in countries with low than countries with high levels of employment protection legislation. We also find that such negative effect of EPL is slightly stronger for countries near the technology frontier, in the manufacturing sector and after the 1990s. We interpret these results suggesting that technology adoption depends on the skill level of the workforce and on the capacity of firms to adjust employment as technology changes: therefore, firing costs have a stronger impact in sectors where technical change is more skill-biased and technology adoption more important.     

Relating the environmental impact of consumption to household expenditures: An input-output analysis

In this paper we evaluate the relationships between household expenditures and the environmental impact categories climate change, acidification, eutrophication and smog formation, by combining household expenditures with environmentally extended input-output analysis. Expenditure elasticities are examined with regression analysis, and are compared and interpreted on the basis of insight at the product level. With data from the Netherlands in the year 2000, we find that environmental impact increases with increasing household expenditures, although the degree to which the environmental impact increases differs per impact category. Climate change and eutrophication increase less than proportionally with increasing expenditures. Acidification increases nearly proportionally with increasing expenditures, whereas smog formation increases more than proportionally. It appears that the mix of necessities and luxuries to which an environmental impact is related is essential in explaining the relationship.     

A bivariate probit approach to the determination of employment: a study of teen employment differentials in Los Angeles County

Following a bivariate probit approach and using the 1990 Public Use Microdata Samples (PUMS) for Los Angeles County, this study shows that the employment of teenage workers depends on both the worker's participation decision as well as the employer's hiring decision. Omission of the role of participation decision from the estimation of employment probability yields misleading evidence of hiring discrimination against Blacks. This evidence, however, disappears when the participation and hiring equations are estimated jointly in a bivariate framework. The study finds no evidence of discrimination against females and Latinos. In addition, the study shows that family, household and neighbourhood characteristics play significant roles in the determination of teen employment.     

A general equilibrium approach to wage bargaining and employment

This paper attempts to capture the effects of cyclical fluctuations in business activity on factor prices and employment levels in a two-sector model with wage bargaining.     

Endogenous employment rate in the efficiency wage shirking approach

The aim of New Keynesian theorists is to obtain Keynesian results on the basis of maximizing behavior. Accordingly, the New Keynesian shirking models depict a world of fully rational maximizing agents where equilibrium unemployment is the main consequence of the payment of efficiency wages. The problem is that oversimplified nature of most shirking models has until now prevented a full investigation of the interdependence of unemployment, the effort supplied by workers and labor demand. This article shows that the existence of this interdependence weakens the whole approach. In particular, when the unemployment rate is considered a truly endogenous variable, the stability of the macroeconomic equilibrium is generally incompatible with the existence of unemployment ascribed to the fact that firms pay efficiency wages.     

The substitutability between parent company and foreign affiliate employment in Europe

This paper examines the substitution pattern between parent company and foreign affiliate employment of European multinationals. The data is drawn from the AMADEUS and BANKSCOPE firm-level databases and covers parent companies in 14 high-wage European countries (EUR14) and their affiliated companies in the wider Europe including locations in the low-wage Central and East European countries (CEEC) for the period 2000–2004. We find that the substitution elasticity between employment of the EUR14 parent companies and employment in their foreign affiliates in the CEEC is quite low. Furthermore, the substitution possibilities are higher between parent company and affiliate employment in other West European countries than those between parent company and affiliate employment in the CEEC. Finally, we find that the output change of the parent company and to a lesser extent that of the foreign affiliates is more important than changes in relative wages in determining the relative labour demand.     

Working-time reduction and employment: experiences in Europe and economic policy recommendations

The paper seeks to evaluate the evidence on the employment effectsof the collective working-time reductions in Europe over thepast 20 years. While theoretical analyses produce contradictoryassessments, most empirical studies show positive employmenteffects but take insufficient account of these conditions underwhich the reductions in working time were implemented. Theseconditions for the success of collective working-time reductionsinclude an active training policy designed to minimise skillshortages in the labour market, the modernisation of work organisation,wage increases in conjunction with productivity gains and amore equal income distribution.
