ENDOGENOUS HUMAN CAPITAL INVESTMENT AND THE INTERACTION OF FRONTIER AND ADOPTIVE KNOWLEDGE ON GROWTH AND WAGE INEQUALITY

A three-sector, overlapping-generations growth model endogenizes the opportunity cost of human capital formation and the relative skill requirements of invention, innovation, and adoption of general-purpose technologies. As a result, the relative wage of skilled workers is a function of the endogenous ratio of total-to-adoptive knowledge (where the difference in knowledge stocks is frontier knowledge). Comparative statics are examined for the model's seven parameters. Simulations (representing a transition with phases to a more complex level of economic development) are presented for simultaneous exogenous shocks capable of matching (i) observed inverse movements of the relative wage and the detrended relative supply in the USA, (ii) the sharp slowing and recovering US multifactor productivity growth data since the 1970s, and (iii) a reconciliation of data used to support or deny skill-biased technological change as a major force driving up the relative wage since 1980.     

Micro and macro dynamics: Industry life cycles,inter-sector coordination and aggregate growth

Technological change directly affects economic growth by exploiting and exploring technological opportunities, thus determining productivity growth and income. However, technological change also affects the composition of the economic system, which itself constitutes an important prerequisite for economic growth. The first aim of this paper is to show that the growing variety of the economic system, determined by the emergence of new products and services and leading to new industrial sectors, can allow the long term continuation of economic development, even when the employment creating capacity of individual sectors falls. The second aim is to illustrate the impact of micro variables on the meso-level, that is, on the sectoral composition of an economy, as well as on its macro-economic performance.

The effect of science and technology parks on firms’ performance: how can firms benefit most under economic downturns?

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.     

Economic growth, skill-biased technical change and wage inequality: A model and estimations for the US and Europe

In recent literature skill-biased technical change has been viewed as a major cause for wage inequality. Some modelling and presentation of stylized facts have been undertaken for US time series data. A preliminary study of wage inequality in a model with knowledge as input in an aggregate production function has been presented by Riddell and Romer [General Purpose Technologies and Economic Growth, 1998, MIT Press]. Although some important forces determining wage inequality are widely accepted we know little about the quantitative impact of each source and differences across countries. We present a growth model of the Romer type with innovation-based technical change and two skill groups where the growth of knowledge, the relative supply of the two skill groups, externalities and substitution effects among the two groups are the driving forces for wage inequality. We undertake estimates for US time series data and contrast those estimates with results from some European countries. In particular, we compare parameter estimations for US and German time series data. The paper concludes that there is less wage inequality across skills in Europe in contrast to the US on the macroeconomic level. But, considering disaggregated data we observe some increases in inequality for Germany, too. Although our model reveals important variables for the explanation of wage inequality there may, however, also be other factors, such as trade unions, which have impacted the wage spread.     

Employee Profit-sharing and Labor Extraction in a Classical Model of Distribution and Growth

This article sets out a classical model of economic growth in which the distribution of income features the possibility of profit-sharing with workers, as firms choose periodically between two labor-extraction compensation strategies. Workers are homogeneous with regard to labor power, and firms choose to compensate them with either only a conventional wage or a share of profits on top of this conventional wage. Empirical evidence shows that labor productivity (i.e. labor extraction) in profit-sharing firms is higher than labor productivity in non-sharing firms. The frequency distribution of labor-extraction employee compensation strategies and labor productivity across firms is time-variant, being driven by satisficing imitation dynamics from which we derive two significant results. First, heterogeneity in labor-extraction compensation strategies across firms, and hence earnings inequality across workers can be a stable long-run equilibrium outcome. Second, although convergence to a long-run equilibrium may occur with either a falling or increasing proportion of profit-sharing firms, the share of net profits in income and the rates of net profit, capital accumulation and economic growth nevertheless all converge to the highest possible long-run equilibrium values.     

On the nature,function and composition of technological systems

This paper suggests that the economic growth of countries reflects their developmental potential which, in turn, is a function of the technological systems in which various economic agents participate. The boundaries of technological systems may or may not coincide with national borders and may vary from one techno-industrial area to another. The central features of technological systems are economic competence (the ability to develop and exploit new business opportunities), clustering of resources, and institutional infrastructure. A technological system is defined as a dynamic network of agents interacting in a specific economic/industrial area under a particular institutional infrastructure and involved in the generation, diffusion, and utilization of technology. Technological systems are defined in terms of knowledge/competence flows rather than flows of ordinary goods and services. In the presence of an entrepreneur and sufficient critical mass, such networks can be transformed into development blocks, i.e. synergistic clusters of firms and technologies which give rise to new business opportunities.     

Knowledge externalities,innovation and growth in European countries: the role of institutions

This paper provides an empirical analysis of the linkages between institutions and economic growth in the European context and highlights innovation as the intermediate variable that drives this interplay. Building on the literature in the evolutionary approach to the economics of innovation and in the economic growth theory with a political economic perspective, we assume that knowledge externalities can fully take place where institutions guarantee a level playing field in the access to knowledge. We estimate the effects of a set of relevant institutional variables on the growth rate of technological knowledge and per capita GDP for a sample of European countries. The empirical analysis confirms that institutions that tend to equalise opportunities to innovate significantly amplify the impact of an exogenous increase in the knowledge base on the growth rate of per capita GDP.

THE CONCEPT OF MACROECONOMIC COST AND ITS UTILITY

The proposed "Variable Domestic Cost" includes all net payments by sectors belonging to the productive system (enterprises, credit institutions and government) to all other sectors (households, private non-profit organizations and the rest of the world). Compared with the rate of growth of demand, represented by Gross Domestic Marketable Product at current prices, the rate of growth of VDC per unit produced forms the "profitability function of the nation." Profitability is positively related to the rate of economic growth and to the price/cost relation. A relative deceleration of unit VDC stimulates economic growth, which enlarges the positive difference between price and cost, and that, in turn, accelerates economic growth. Inversely, a relative acceleration of unit VDC brakes economic growth, while a slowdown in production raises unit costs and depresses prices. The resulting fall in profitability stops economic growth.
The main explanatory variables of demand are World trade, monetary and fiscal policy and import prices. The main components of VDC are enterprises' wage costs, social benefits minus social contributions and the government wage bill minus direct taxes payable by households. The fact that in West Germany all these unit costs were increasing more slowly than in France explains why Geman economic growth, much slower than French before 1975, outpaced it after that year, achieving a lower rate of inflation, a larger positive balance of trade and a higher appreciation of the national currency.
The concept of VDC is a useful contribution to the theories of inflation and of economic fluctuations and provides a possible explanation of structural unemployment. Maintaining VDC at a lowest possible level should be considered a major object of economic policy.     

Technological development and rates of return to investment in a catching-up economy: the case of South Korea

Technological change has been the key driving force in the growth spurt of East Asia in the past decades. Assimilation theorists stress the importance of building up technological capabilities and demonstrate the dynamic processes of technology assimilation and learning, which have taken place through case-studies. However, especially after the Asian financial crisis, it can be argued that it is not enough to show that firms have increased their technological competencies. It is also important to assess the economic returns to the pecuniary investment flows linked with these learning processes. The main idea put forward in this paper is that investment in technology is necessary to maintain rates of return to physical capital investment, and that this is increasingly difficult, the closer a country gets to the global technology frontier. This idea finds support in an analysis of the development of four technology-intensive industries in South Korea, using technology investment indicators such as foreign direct investment, R&D expenditures and technology licensing fees. The results suggest that a strategy of technological diversification might generate higher returns to investment than a pre-occupied search for industrial leadership.

Is the skills mismatch important under skill-biased technological change and imperfect substitutability between immigrants and natives?

This paper contributes to the debate on the benefits and costs of immigration, by evaluating how the mismatch between educational attainment and occupations induced by immigration affects output per worker, the wage premium, and the economy's technological level in OECD host countries. To that end, we use an R&D growth model in which technological knowledge can be directed to either low- or high-skilled labour and thereby drives the dynamics of the key economic variables. There tends to be a significant economic impact of the skills mismatch due to immigration, which amplifies the effects of the mismatch in the native population. Nevertheless, countries with a higher contribution of immigration to the skills mismatch are not necessarily those with the higher contribution in terms of economic effects. Moreover, the size and sign of the latter may vary depending on the assessed economic indicator and from country to country. Cross-country differences regarding the initial level of the high-to low-skilled ratio and the size of its shift due to immigration play a crucial role.     

A fuzzy-based roadmapping model for enhancing high-tech small firms’ technological entrepreneurship capabilities: cases of Iran

ABSTRACT

Technology-based firms need to survive via technological changes. Technological entrepreneurship is concentrated on identifying and exploiting the tech-opportunities for creating product innovation. This paper introduces a fuzzy-based tool to promote innovation throughout firms in order to enhance technological entrepreneurship capabilities (TEC). The effort involves identifying components of TEC to develop the inference system, specifying the fuzzy relationship among these components, assessing the TEC in firms, and designing a TEC roadmap after a fuzzy-based gap analysis. Designed roadmaps introduce technological change priorities as a growth path to firms to move up along the ladder of competitiveness. Based on the results, a method for categorizing firms into four distinct levels that involve passive, reactive, proactive and innovative is introduced. Hence, firms have an action plan to enhance TEC from passive to innovative level in a time-based transition pathway.     

Technological change and institutional inertia: a game-theoretic approach

In this paper, we study a co-evolutionary model of economic change at two hierarchical levels. At the lower level, institutions are given and the focus is on how resources are allocated and innovation produced in response to the pay-off structure induced by prevailing institutions. At the higher level, it is the institutions themselves that change as the outcome of a process of social bargaining. The main objective of the paper is to study the interaction between these two levels of change, attempting to provide some insight on issues like technological/institutional divergence, technological dead-end, institutional inertia, etc.It appears that evolutionary economics must be the theory of a process of cultural growth as determined by the economic interest, a theory of a cumulative sequence of economic institutions stated in the terms of the process itself.

Canadian city housing prices and urban market segmentation

Abstract .  This paper provides a detailed empirical analysis of Canadian city housing prices. We examine the long-run relationship between city house prices in Canada from 1985 to 2005 as well as idiosyncratic relations between city prices and city-specific variables. The results suggest that city house prices are only weakly correlated in the long run and that there is a disconnect between house prices and interest rates. City-specific variables such as union wage levels and the issuance of building permits tend to be positively related to existing city house prices. Surprisingly, there is mixed evidence with respect to standard measures of economic activity such as per capita GDP and interest rates.     

Technology and outsourcing: An explanation to the rising wage gap

The recent phenomenon of widening skilled–unskilled wage gap in both North and South has been either explained by a technological change or by increasing trade or globalization. The paper provides a new explanation and emphasizes that it is neither technology nor trade alone but both that have contributed to the widening wage inequality. It argues, using a two-country occupational choice model, that any technological improvement in North results in a rise in the skilled–unskilled wage gap in North via an increase in the productivity of skilled labor followed by a rise in the same in South via trade or the outsourcing activities of the northern firms. The extent of outsourcing or the number of northern firms that outsource jobs to South is endogenously determined in the model. The paper also analyzes some major economic impacts of such a technological upgradation in North on the southern economy.

R&D,TECHNOLOGY SPILLOVERS AND STOCK PRICES†

Abstract. Theories of endogenous growth suggest that technological progress is driven by firms’ own R&D effort and knowledge spillovers. Using panel data for US firms over the period from 1990 to 1999 this paper tests the influence on stock prices of technological spillovers through firms’ purchase of intermediate products from other firms. The empirical results show that stock prices are significantly positively affected by knowledge spillovers through the input of intermediate products.     

Technological Profiles And Economic Performance In The Italian Manufacturing Sector ∗

This paper applies multivariate analysis to a rich data set on technological innovation, in order to identify typical patterns of technological change. To single out the dominant forms of technological behaviour, twelve variables have been selected approximating firms' technological sources and innovation results. Multivariate analysis was applied to identify six main clusters or dominant technological profiles. Each cluster was then interpreted on the basis of a larger set of variables concerning firms' technological and economic performance. The results confirm recent emphasis placed by scholars of technical change on variety of bchaviour in technical change and industrial organization and, more specifically, Pavitt's seminal attempt at a classification of this variety. However, our clusters are somewhat more numerous than Pavitt's, thus showing a more complex combination of technological input and output. Moreover, representative industries of each cluster are less easily recognized as a less marked sectoral characterization of clusters emerges. The latter result seems to imply that variety in technological change is also shown by the existence of different technological trajectories and strategies within the same sector. We suggest that the diffuse nature of recent technical change has given firms greater freedom of strategic choice among different technological strategies.
