Measuring (in a time of crisis) the impact of broadband connections on economic growth: an OECD panel analysis

Technological innovation has always been considered a major stimulus for economic growth. High-speed internet access via broadband infrastructure has undergone rapid development since the end of the 1990s, thanks to the deployment of both fixed and mobile technologies. The present study investigates the impact of fixed broadband diffusion as a technological determinant of economic growth on the basis of a panel of 23 OECD countries over 15 years (1996–2010). The time horizon chosen is suitable for verification of the causal effect on growth of the transition from traditional copper to partially fibre networks. Through implementation of a dynamic panel by using the generalized method of moments (GMM) combined with an instrumental variable (IV) two-stage approach, we found a positive correlation between broadband diffusion and economic growth, even after controlling for countries initial endowment of information and communication technologies (ICT) and for the years of economic crisis. Our main finding provides evidence, through a continuous time interpretation of our estimations, of a quantitatively relevant relationship between broadband diffusion and economic dynamics in the short, medium and long runs. Our findings may be useful to policy makers in that they permit forecasting of the benefits of further transition from broadband to ultra-wide broadband networks.

PRODUCTIVITY AND BUSINESS CYCLES IN JAPAN: EVIDENCE FROM JAPANESE INDUSTRY DATA*

Constructing a database of 37 industries, we examine whether the measured productivity in Japan is pro‐cyclical and investigate the sources of this pro‐cyclicality by using the production function approach employed by Hall (1990) and Basu and Fernald (1995). The aggregate Solow residual displays pro‐cyclicality. A large number of industries show constant returns to scale. No significant evidence for the presence of thick‐market externalities is found. Our results also hold when we consider labour hoarding, part‐time employment, and the adjustment cost of investment. The results indicate that policies to revitalize the Japanese economy should concentrate on promoting productivity growth.     

Unwrapping some euro area growth puzzles: Factor substitution, productivity and unemployment

In this paper, we estimate a long run supply-side system incorporating a CES production function with time-varying factor-augmenting technical progress for the euro area over the period 1970–2005. We find that the elasticity of substitution lies below unity at 0.7, that labor-augmenting technical progress is dominant in the long run while capital-augmenting technical progress plays an important role in the interim period. Importantly, we also find evidence of a structural break in the pattern of biased technical progress towards the end of the 1990s. Our results help to solve two puzzles in Europe’s recent growth experience which differ markedly from the US experience. The first is related to the effects of the IT boom in the 1990s on productivity growth in Europe. The second puzzle concerns the changes in the “Okun’s law” relationship, linking growth to the reduction of unemployment, which are observable in Europe since the late 1990s.     

Skill-Specific rather than General Education: A Reason for US–Europe Growth Differences?

In this paper, we develop a model of technology adoption and economic growth in which households optimally obtain either a concept-based, general education or a skill-specific, vocational education. General education is costly to obtain, but enables workers to operate new production technologies. Firms weigh the cost of adopting and operating new technologies against increased profits and optimally choose the level of adoption. We show that an economy whose policies favor vocational education will grow slower in equilibrium than one that favors general education. More importantly, the gap between their growth rates will increase with the growth rate of available technology. By characterizing the optimal Ramsey education policy we also demonstrate that the optimal subsidy for general education increases with the growth rate of available technology. Our theory suggests that European education policies that favored specialized, vocational education might have worked well, both in terms of growth rates and welfare, during the 1960s and 1970s when available technologies changed slowly. However, in the information age of the 1980s and 1990s when new technologies emerged at a more rapid pace, they might have contributed to an increased growth gap relative to the United States.     

EMPLOYMENT PROTECTION,TECHNOLOGY CHOICE,AND WORKER ALLOCATION

We show empirically that high‐risk sectors, which contribute strongly to aggregate productivity growth, are relatively small and have relatively low productivity growth in countries with strict employment protection legislation (EPL). To understand these findings, we develop a two‐sector matching model where firms endogenously choose between a safe technology and a risky technology. For firms that have chosen the risky technology, EPL raises the costs of shedding workers in case they receive a low productivity draw. According to our calibrated model, high‐EPL countries benefit less from the arrival of new risky technologies than low‐EPL countries. Parameters estimated through reduced‐form regressions of employment and productivity on exit costs, riskiness, and in particular their interaction are qualitatively similar for actual cross‐country data and simulated model data. Our model is consistent with the slowdown in productivity in the European Union relative to the United States since the mid‐1990s.     

Investment-Specific Technical Change in the United States (1947–2000): Measurement and Macroeconomic Consequences

By extrapolating Gordon's measures of the quality bias in the official price indexes, we construct quality-adjusted price indexes for 24 types of equipment and software (E&S) from 1947 to 2000 and use them to measure technical change at the aggregate and at the industry level. Technological improvement in E&S accounts for an important fraction of postwar GDP growth and plays a key role in the productivity resurgence of the 1990s. Driving this finding is 4% annual growth in the quality of E&S in the postwar period and more than 6% annual growth in the 1990s. The acceleration in the 1990s occurred in every industry, consistent with the idea that information technology represents a general-purpose technology. Furthermore, we measure for the aggregate economy and different sectors the “technological gap”: how much more productive new machines are compared to the average machine. We show that the technological gap explains the dynamics of investment in new technologies and the returns to human capital, consistent with the Nelson–Phelps conjecture. Since the technological gap continues to increase—it more than doubled in the past 20 years—our evidence supports the view that at least some of the recent increase in productivity growth is sustainable.

Has the structural break slowed down growth rates of stock markets?

In this paper, we use the common structural break test suggested by Bai et al. (1998) to test for a common structural break in the stock prices of the US, the UK, and Japan. On the basis of the structural break, we divide each country's stock price series into sub-samples and investigate whether or not the structural break had slowed down the growth of stock markets. Our main findings are that when stock markets are modelled in a trivariate sense the common structural break turns out to be 1990:02, with the confidence interval including several episodes, such as the asset price bubble when housing prices and stock prices in Japan reached a peak in 1988/1989, the early 1990s recession in the UK, the business cycle peak of July 1990, the August 1990 Iraqi invasion of Kuwait and the March 1991 business cycle trough. Annual average growth rates suggest that the structural break has slowed down the growth rate of the US, the UK and Japanese stock markets.     

Digital technologies,knowledge spillovers,innovation policies,and economic growth in a creative region

We theoretically study the impact of two innovation policies on economic growth in a region that is creative in the sense of Richard Florida and that uses digital technologies to produce a final consumption good. The use of these digital technologies in our creative region gives rise to incomplete knowledge spillovers. Our analysis generates three salient findings. First, we characterize the balanced growth path (BGP) equilibrium. Second, we solve the social planner's problem, describe the Pareto optimal allocation of resources, and then compare the Pareto optimal allocation with the BGP equilibrium allocation. Finally, we study the impacts that a research subsidy and a particular patent policy have on economic growth in our creative region and then we relate our findings to the incompleteness of the above-mentioned knowledge spillovers.

The shift from theory to innovation: the evolution of Brazilian research frontiers 2005–2011

Proliferation of emerging economies as significant sources of competitive knowledge is a key feature of globalisation, often driven by government policies fostering domestic research-based innovation capabilities. To cast light on this common emerging economy effort to move from catch-up towards the global innovation frontier, we analyse the evolution of the focus of Brazilian research frontiers 2005–2011 with bibliometric methods. Our results demonstrate a gradual and moderate shift from theoretical scientific knowledge to more innovation-centred knowledge in the most influential Brazilian research, indicating the increased prominence and quality of innovation focused efforts in country's knowledge system. Thus, the recent expansion of Brazil's innovation system is accompanied by qualitative transformations of the research system, in part driven by nationally emerging research fields and technologies. Conceptually, we consider the overall importance of scientific research for developing and emerging economy innovation system build-up.     

Scale And Scope In Technology: Large Firms 1930/1990

We examine historical empirical patterns of change in corporate. technological scale and scope. Much literature on scale and scope by business and economic historians has conflated product markets and technology together. However, given the technologically complex environment of the late twentieth century, the relationship between scale and scope in production and products is not simple, and conflated discussions may be naive. Consequently we have two aims. Firstly, we wish to see if technological scale and scope follow the historical pattern of broader notions of scale and scope. Secondly, given increasing technological complexity, we consider whether the nature of corporate technological scope has changed over time.

Using data drawn from the University of Reading's patents database, we examine the technological activities in 32 of the world's historically largest patenting firms over the period 1930 to 1990. Shin-sham analyses based on panel-data regressions examine the different influences on technologicascope over time. A technological trend closely resembling that of broader notions of scale to scope is observable in most of the sectors. although it does not proceed uniformly. We also find, that whilst increases in corporate technological scope through diversification are not particularly linked to technological relatedness in recent times, they are periodically influenced by the rise of pervasive, fast-growing new technologies.     

Changes in job security and their causes: An empirical analysis for France, 1982-2002

In this paper, we analyze the changes in the risks of involuntary job loss in France between 1982 and 2002. We find that these risks are higher in the 1990s than they were in the 1980s. We develop an econometric analysis to separate the effects of institutional changes from the effects of new technologies. Our estimates show that the rise in job loss rates is significantly more pronounced in industries that have the largest share of R&D workers and the largest rate of new technologies’ users. These findings suggest that technological changes contribute to decreasing the incentive to keep workers for long period of time and to increasing job insecurity.     

Economic growth and poverty: a tale of two decades

The relationship between poverty and economic growth is reexamined using pooled cross section and time series estimates of state level poverty. Empirical evidence is provided for both cash and comprehensive income headcounts and Sen indexes of poverty. Particular emphasis is placed on the differential impacts of growth on poverty in the long economic expansions of the 1980s and 1990s. Contrary to prior work, we find that the long-term effects of growth did not strengthen and may have actually diminished during the 1990s.     

Determinants of economic growth: Different time different answer?

Almost all studies that use Bayesian model averaging to identify robust growth determinants focus on the growth period between 1960 and the 1990s. We apply Bayesian Model Averaging to a rolling time window of 20 and 35 years using a newly compiled dataset with 37 growth determinants for the years 1960 to 2010. Our findings indicate instabilities in the inferences on growth determinants across growth periods. In line with prior research, we find support for robust ambiguity in early growth periods, that is, cross-country growth regressions provide little support for some growth determinants being more important than others. However, determinants related to demography, education, trade, investment and to some extent religion seem to matter in the subsequent growth periods with education and demography being most important in recent growth periods.     

Structural transformation and its relevance for economic growth in Sub‐Saharan Africa

In this paper, we analyze the role of structural transformation in view of the remarkable growth performance of Sub‐Saharan African countries since the late 1990s. Our analysis covers 41 African countries over the period 1980 to 2014 and accounts for structural transformation by employing the analytical frameworks of (1) growth decomposition and (2) growth regression. Even though the low‐productive agricultural sector continues to employ most of the African workforce, our results reveal that structural transformation has taken place and that it has contributed significantly to African growth in the period 1980‐2014.     

Earnings growth and the bull market of the 1990s: Is there a case for rational exuberance?

This paper examines whether permanent earnings growth, crucial to stock valuation, increased during the 1990s, as suggested by proponents of the new economy. Using S&P 500 earnings for the period of 1951–2000, we do not find strong evidence of either a one-time structural break or gradual change. However, the confidence interval on permanent earnings growth is wide enough to include an increase that is roughly consistent with the bull market of the late 1990s. Thus, we cannot reject a rational basis for that exuberance.     

Ethnic fractionalisation, migration and growth

This paper has the aim of contributing to the existing research by analysing two particular topics. First of all, we show that the model specifications by Alesina et al. (J Econ Growth 8:155–194, 2003), which connects high ethnic fractionalisation to lower growth via bad policy variables, cannot fully explain the negative ethnic fractionalisation effect of the 1990s Sub-Saharan African growth experience. Moreover, we show that the remaining negative effect of ethnic fractionalisation on growth in Sub-Saharan Africa in the 1990s is due to an increased importance of adverse governance. Second, and on a very different note, we empirically investigate if ethnic fractionalisation might have a positive effect in a nation which is ethnically diverse due to immigration. There is evidence that it is important to distinguish between these two different kinds of ethnic fractionalisation.     

Social mobility and inequality in urban China: understanding the role of intergenerational transmission of education

China’s rapid economic growth since the late 1980s has been accompanied by great economic and social transformations, which have resulted in a sharp increase in income inequality. This article contributes to the literature of social mobility in China by examining the impact of parental education on the education of their children. Using the 1990 and 2000 Chinese Population Censuses, we employ nonparametric estimation strategies to provide a systematic investigation of intergenerational transmission of education in urban China. We find evidence of increasing parents–children educational correlations. Our results raise concerns regarding economic inequality in urban China as high intergenerational persistence of education is expected to be a barrier to equal opportunities in children’s education attainments and their future labour market outcomes.     

A Permanent Change in the Route to Owner Occupation?

This paper attempts to explain why home ownership rates among young adults fell in the early 1990s when various indicators suggested it had become more affordable. As a potential explanation, we focus on the relatively slower growth in their incomes and argue that this could signal a fundamental change in behaviour, a change in route adopted into owner occupation, induced by structural economic change. In examining the implications for housing tenure, we use a conditional fixed effects multinomial logit model to exploit the information on the tenure choice and the timing of transitions in the British Household Panel Survey. Our results reveal that relatively slower income growth contributed significantly to this decline and that ignoring the intertemporal correlation in micro‐panels generates inconsistent results.
