Information and communication technology diffusion and skill upgrading in Korean industries

We examine the relationship between the directly observable indicator of new technology, information and communication technology (ICT) investment intensity, and skill upgrading by analyzing changes in employment and wage structure of 25 Korean industrial sectors over the 1993–1999 period. The estimation results indicate the following implications. First, although ICT expenditure and investment have increased sharply since 1993, it appears that ICT investment has begun to be complementarily combined with skilled labor only since 1996. Second, our results support the ‘limited substitution hypothesis’. ICT has substituted low-skilled non-production workers, whereas the increased demand for high-skilled workers is driven by ICT diffusion in the second sub-period. This asymmetric trend between high-skilled and low-skilled non-production workers in Korea reveals significant differences in comparison with the experiences of other OECD countries. Third, the existence of substitutability between ICT diffusion and low-skilled non-production workers in Korea may cast doubt on the appropriateness of the non-production workers' category, a category regarded as a proxy variable of high-skilled workers in most previous studies.     

Information and the persistence of private-order contract enforcement institutions: An experimental analysis

We study an experimental market in which some sellers are prone to moral hazard, and in which a private-order contract enforcement institution exists that can mediate trade and prevent sellers from reneging on their contractual obligations. Using the institution to resolve the moral-hazard problem is costly. We demonstrate that in this market, the utilization of the private-order contract enforcement institution may make public and private market signals uninformative and inhibit learning. We study whether this potential information externality can limit adaptation away from the private-order institution when it is efficient to do so. Consistent with theory, we find inefficient persistence when the institution is used, but by contrast, efficient adaptation in other situations. Providing information to individuals who are using the private-order institution allows them to partially adapt.     

Factor analysis of demand growth for information technology input in Japan

The purpose of this article is to decompose demand changes for factor input and explore the factor that information technology (IT) capital stock has largely increased in Japan. The Allen partial elasticities of substitution are calculated and the variations in factor input demand are broken down into two effects—price effect and output effect, using industry-level data. From an estimation of the total cost function, the following conclusions are presented. While IT capital stock and ordinary capital stock are complementary, IT serves as a substitute for labor. The factors influencing the high growth rate in IT capital stock are the decrease in the prices of IT and ordinary capital services, and the increase in the labor price, in addition to the output effect. On the other hand, labor demand declines due to both the downward rigidity of wages and the decrease in prices of two kinds of capital services.     

Skilled and unskilled wage dynamics in Italy in the 1990s: changes in individual characteristics,institutions, trade and technology

In this paper, we use individual micro data on workers combined with industry and regional data to study the wage dynamics of skilled and unskilled workers in Italy in the 1991–1998 period. In contrast to previous empirical studies, our data make it possible to analyse, within a single framework, the role of many of the factors indicated in the literature as possible determinants of skilled and unskilled wage dynamics: changes in the individual characteristics of workers, changes in labour market institutions, increasing international integration, and skill‐biased technological progress. Our results show that international integration, both in terms of trade in goods and in terms of international labour mobility, plays a role in determining the wage dynamics of skilled (white‐collar) and unskilled (blue‐collar) workers. Moreover, in line with labour economics research, our findings show that the individual characteristics of workers and the institutional variables are more relevant in explaining skilled and unskilled wage dynamics than wage differentials.     

Evaluating the performance of higher education institutions in Europe: a nonparametric efficiency analysis of 944 institutions

Although a long tradition exists of studying the economics of education, performance comparisons of different kinds have traditionally been difficult to undertake. An important impediment has been the lack of comparable data. To a large extent, this study remedies the shortcomings of earlier studies. Our contribution is twofold. First, the current higher education policy of contraction and economizing, common to most European countries, make knowledge of potential efficiency gains crucial. Second, a unique database allows us to study a broad diversity of organizations as well as organizations located in a number of different European countries. The study suggests evaluating higher education institution (HEI) performance in a production theory context, applying the well-known data envelopment analysis (DEA) method to a cross section of 944 HEIs in 17 European countries. The DEA approach is particularly suitable in this context where little is known about production technologies and economic behaviour of the HEIs. On average, provision of education is found to be most efficient in the Slovak Republic followed by Belgium and Latvia, while Denmark and Norway display the lowest efficiency. The study also indicates a positive relation between efficiency and HEI size and efficiency and research intensity. Furthermore, the study points to the importance of continued data collection.     

A disaggregated analysis of EU imports: the implications for the study of patterns of trade and technology

This paper examines trends in the unit prices of manufacturedimports into the European Union (EU) in the period 1988–2002.This is undertaken at a high level of disaggregation, and itis this decomposition which we believe has important implicationsboth for a range of bodies of economic analysis and for policy.The analyses undertaken in this paper confirm that disaggregationmatters in helping to identify unit-price trends. We have alsoshown that unit-price trends vary with the type of economy exportinginto Europe and the type of product being exported, and thatthese results are robust at high levels of disaggregation.     

Looking for the workforce: the elderly,discouraged workers,minorities, and students in the Baltic labour markets

This paper looks at the evolution of the labour markets in Estonia, Latvia, and Lithuania since the beginning of transition until 2003, with a particular focus on labour force participation. How did labour supply in the Baltic countries respond to changes in minimum wages, unemployment benefits and retirement regulation? Do the marked differences in labour market policies between the countries result in different patterns of participation? What are the obstacles to and driving forces of participation? We find that relative contribution of participation and demographic trends to the dynamics of the labour force varied substantially both over the years and across the three countries. Participation, in turn, has been shaped by sometimes complicated interactions between schooling decisions of the youth, retirement, policy changes, and external shocks. Resulting differences in trends and patterns are quite substantial, indicating that there is a room for increasing participation in each of the countries. Panel data analysis of determinants of participation and discouragement based on labour force survey data suggests that increasing after-tax real minimum wage has significant positive effects on participation and reduces discouragement in Lithuania. In Estonia, by contrast, a positive effect of minimum wage on participation is found only for teenagers of both genders and for young males. We do not find any evidence that partner’s wage has a negative effect on participation. Ethnic minorities, especially females, in all three Baltic countries are less likely to be in the labour force, other things equal.     

New Labour at work: long-term unemployment and the geography of opportunity

New Labour has placed great faith in active labour market policiesto address problems of long-term unemployment and poverty. Thispaper considers the effectiveness of welfare-to-work programmesin light of persistent regional employment disparities withinthe UK. It is argued that the government has proceeded froma flawed analysis of the causes and magnitude of long-term unemployment,framing the issue in terms of ‘worklessness’ andneglecting demand-side concerns of job availability and jobquality.     

An empirical analysis of the demand for houses durables and nondurables

A standard neoclassical model of intertemporal choice is applied to households' demand for nondurables, durables and houses, so that particularly the role of credit rationing is stressed. Empirical analysis is performed with Finnish quarterly data. The main result of the study is that relative prices are of little significance, whereas credit rationing is found to play an important role, affecting both the desired levels of demand and the speed of adjustment.     

网络经济虚拟性的理论分析与实证检验

网络经济在四十年的发展过程中,其投入产出的关系呈现出完全不同的阶段性特征,对这一现象的解释一直是学术界争论的热点。目前,西方经济学对此的解释争议较大,且缺乏整体性;由于网络经济中新的生产方式对马克思经典的劳动价值论提出了挑战,马克思主义经济学也不能很好地解释上述问题。我们以马克思的劳动价值论为基础,结合网络经济虚拟性的根本特征,对网络经济发展过程中不同阶段表现出的特征给出一个政治经济学的解释。     

The role of market-oriented institutions in the deployment of renewable energies: evidences from Europe

Focusing on European countries, this article investigates the link between market-oriented institutions, as measured by the Economic Freedom Index, and the production of energy from renewable sources. A dynamic panel approach shows that this correlation is positive and significant while the subcomponents of the Economic Freedom Index reveal that not all market-oriented institutions have a similar impact. Indeed, long-term price stability and freedom to trade boost the reliance on renewable energies whereas the importance given to markets rather than governments has no significant impact.     

Evaluating the effects of investment in information and communication technology

Most of the studies on the consequences of information and communication technology (ICT) have been focused on US aggregate data. In contrast to these studies, this paper empirically assesses the industrial effect of ICT investment on three key variables – real output, employment, and labour productivity – in some European Union-15 (EU-15) countries and the USA using panel-vector autoregression models. An increase in ICT investment is positive for the economies of these countries, giving rise to larger growth in real output, employment, and labour productivity at the industrial level. The pattern of responses to changes in ICT investment is quantitatively diverse across most of the EU-15 countries studied and in the two types of industries considered (i.e. ICT-intensive and less intensive industries). Moreover, the positive impact on labour productivity in ICT-intensive industries is larger after the mid-1990s, with the USA being the most positively affected country.     

A patent-based cross impact analysis for quantitative estimation of technological impact: The case of information and communication technology

The increasing syntheses and interactions between various technologies increase the usefulness of cross impact analysis (CIA) as a method for forecasting and analyzing them. Conventional CIA depends on an expert's qualitative judgment or intuition and thus it is difficult to evaluate quantitatively the impact of one technology on another. In this study, we employ patent analysis in CIA to examine such impacts between technologies based on multiple patent classifications. Patent information is used for facilitating quantitative and systematic approach in CIA. The distinctive feature and main contribution of the proposed approach is the overcoming of the limitations of conventional CIA, by employing conditional probabilities based on the patent information. The classification of patents, particularly the multiple classifications, is used to evaluate the relationships between technologies. As an illustration, a patent-based CIA with information and communication technologies (ICTs) was conducted. Firstly, the patent-based cross impact among ICTs was calculated. Secondly, the technology pairs were classified based on the cross impact score between ICTs. Thirdly, a cross impact network was constructed to identify the complex relation among ICTs. Finally, the changes in cross impact scores between technologies over time were analyzed. The results of this research are expected to help practitioners to forecast future trends and to develop better R&D strategies.     

Determinants of demand for green products: An application to eco-label demand for fish in Europe

In this paper, we confront the theoretical motivations of the consumption of eco-friendly products and the factors influencing the European perceptions regarding the fact that “fish caught using an environmentally friendly technique may carry a special label”. We take advantage of the recent integration of non-economic elements in the microeconomic analysis of consumers' behavior in order to highlight the factors leading to their demand for green products. Thanks to an original European survey on seafood product carried out on more than 5000 consumers, we test the influence of intrinsic motivation, information, localization and socio-economic factors on the demand for an eco-label for fish.Our results show a significant connection between the desire for eco-labeling and seafood features, especially the freshness of the fish, the geographical origin of the fish and the wild vs farmed origin of the fish. Moreover, we prove the major role played by the fish price. We also demonstrate that the ecological issue regarding fisheries is highly connected to consumer information, intrinsic motivation and socio-economic status: the typical “green fish consumer” is a young woman, well educated, well informed on the state of marine resources and not very trusting of the regulation of the fisheries. Consumers who are aware of the importance of marine resource preservation have the same profile.     

The extent and cyclicality of career changes: Evidence for the U.K.

Using quarterly data for the U.K. from 1993 through 2012, we document that the extent of worker reallocation across occupations or industries (a career change, in the parlance of this paper) is high and procyclical. This holds true after controlling for workers׳ previous labour market status and for changes in the composition of who gets hired over the business cycle. Our evidence suggests that a large part of this reallocation reflect excess churning in the labour market. We also find that the majority of career changes come with wage increases. During the economic expansion wage increases were typically larger for those who change careers than for those who do not. During the recession this is not true for career changers who were hired from unemployment. Our evidence suggests that understanding career changes over the business cycle is important for explaining labour market flows and the cyclicality of wage growth.

Trends in employment and the employment elasticity in manufacturing, 1971-92: an international comparison

Employment growth in manufacturing is limited by output growthin this sector, but the elasticity of employment with respectto output has varied widely in different regions and economies.This paper focuses attention on the idea that a major determinantof employment elasticity is the way the fruits of output growthare divided between employment growth and wage growth. But beforewe are able to determine the quantitative dimension of the trade-off,we have to allow for two other factors which affect the sizeof the cake available to labour in real terms. These are: (i)the elasticity of the wage bill with respect to output, whichdetermines the trend in the share of labour; and (ii) the priceeffect, depending partly on the rate of inflation and partlyon the movements of producer prices relative to consumer prices.A simple decomposition procedure is outlined in the paper whichallows us to quantify the relative importance of these factors,and hence give a clearer idea of the labour market outcome leaningto one or other of the two interests, employment growth andreal wage growth. The empirical analysis for different regionsof the world is carried out on time series data for the manufacturingsector collected by UNIDO from the national surveys of membercountries for the decades of the 1970s and the 1980s.     

Expectations,uncertainty and institutions. An application to the analysis of social security reforms

The aging process that many developed economies will face in the medium-term is leading to reforms in the public pensions systems in order to solve the potential financial unsustainability generated by the foreseeable increase in the expenditure in pension benefits (assuming that the current social security contributions and the eligibility conditions will remain unchanged). Neoclassical economics defends a radical reform of these systems, substituting the current pay-as-you-go (PAYGO) systems by funded systems. In this paper, using the Post-Keynesian theory as a theoretical framework, we provide an alternative reflection to that proposed by the neoclassical economics about the choice between the alternative pension systems. The focus of the paper is the advantages of the PAYGO pension systems to stabilize the expectations of future income.     

Wages and productivity: the role of labour market institutions in OECD countries

In the context of a monetary union, to keep a territorial equilibrium in terms of economic activity and employment, the relationship between real wages and productivity is crucial. In this paper, empirical evidence about the response of wages to productivity is obtained for 20 OECD countries and the role of labour market institutions to explain differences in this response is analysed.     

Scenarios of technology and innovation policies in Europe: Investigating future governance

In Europe, public research, technology and innovation policies are no longer exclusively in the hands of national authorities: increasingly, national initiatives are supplemented by, or even competing with, regional innovation policies or transnational programmes, in particular the activities of the European Union. At the same time, industrial innovation increasingly occurs within international networks. Are we witnessing a change of governance in European innovation policy? Based on some theoretical assumptions concerning the relationship between the “political systems” and “innovation systems” in Europe, the paper speculates about the future governance of innovation policies, trying to pave ways for empirical analyses. It sketches three scenarios stretching from (1) the idea of an increasingly centralised and dominating European innovation policy arena to (2) the opposite, i.e., a progressive decentralisation and open competition between partly strengthened, partly weakened national or regional innovation systems and finally to (3) the vision of a centrally “mediated” mixture of competition and cooperation between diverse regional innovation cultures and a related governance structure.
