The growth of university spin-offs: a dynamic panel data approach

Evidence suggests that a significant percentage of the university spin-offs (USOs) have a low growth capacity, putting in question the use of public funds to promote this kind of entrepreneurship. In addition, previous studies of the USOs’ growth have not dealt with the dynamic nature of firm growth, which might have led to questionable results. This paper analyses whether the university origin of a firm conditions its growth by applying a methodology which captures this dynamic nature of growth. Using a sample of 469 Spanish USOs and an equivalently matched group of 469 Spanish non-USOs over the period 2001–2010, we find that USOs have more growth than non-USOs, both in terms of sales and employment. In addition, the USOs’ growth is influenced by a set of determinants that differ from those of non-USOs. On the basis of the results, we propose some policies to foster the USOs.     

Human capital and economic growth revisited: A dynamic panel data study

This paper examines the role of human capital on economic growth by using a large panel of data including 93 countries. Given the cross-sectional character in most of the relevant studies, there is a possibility that when the long-run dynamics are considered, education might not be a significant determinant of growth. Following a dynamic panel data approach, the analysis indicates that education has, indeed, a significant and positive long-run effect on economic growth. Moreover, the size of this effect is stronger as the level of education (primary, secondary, and tertiary) increases. This has a straightforward policy implication that governments taking actions towards an expansion of their higher education may well expect larger gains in terms of higher economic growth in their countries. This is a revised version of a paper presented at the Fifty-first International Atlantic Economic Conference, Athens, Greece, March 13–20, 2001, and also at the conference on Post-Euro Era at the University of Ioannina, Greece, January 27–28, 2000. The authors would like to thank participants in both conferences and, in particular, Nick Apergis for his comments and useful suggestions on earlier drafts. The authors remain responsible for any shortcomings of the paper.     

Exports and growth: Granger causality analysis on OECD countries with a panel data approach

This paper investigates the possibility of Granger causality between the logarithms of real exports and real GDP in twenty-four OECD countries from 1960 to 1997. A new panel data approach is applied which is based on SUR systems and Wald tests with country specific bootstrap critical values. Two different models are used. A bivariate (GDP–exports) model and a trivariate (GDP–exports–openness) model, both without and with a linear time trend. In each case the analysis focusses on direct, one-period-ahead causality between exports and GDP. The results indicate one-way causality from exports to GDP in Belgium, Denmark, Iceland, Ireland, Italy, New Zealand, Spain and Sweden, one-way causality from GDP to exports in Austria, France, Greece, Japan, Mexico, Norway and Portugal, two-way causality between exports and growth in Canada, Finland and the Netherlands, while in the case of Australia, Korea, Luxembourg, Switzerland, the UK and the USA there is no evidence of causality in either direction.     

Military expenditure and economic growth across different groups: A dynamic panel Granger-causality approach

Applying GMM (Arellano and Bond, 1991) to panel data of 90 countries spanning over 1992–2006, this paper explores possible relationships between military expenditure and economic growth. Based on the definitions of income levels by the World Bank – high, middle and low – our results indicate military spending leads negatively economic growth for the panels of low income countries with a marginally significance level of 10%. Of four different regional panels (Africa, Europe, the Middle East–South Asia and Pacific Rim), a negative but stronger (5% significance level) causal relationship from military expenditure to economic growth is found for the Europe and Middle East–South Asia regions.     

Energy consumption and economic growth in Asian economies: A more comprehensive analysis using panel data

This paper applies the most recently developed panel unit root, heterogeneous panel cointegration and panel-based error correction models to re-investigate co-movement and the causal relationship between energy consumption and real GDP within a multivariate framework that includes capital stock and labor input for 16 Asian countries during the 1971–2002 period. It employs the production side model (aggregate production function). The empirical results fully support a positive long-run cointegrated relationship between real GDP and energy consumption when the heterogeneous country effect is taken into account. It is found that although economic growth and energy consumption lack short-run causality, there is long-run unidirectional causality running from energy consumption to economic growth. This means that reducing energy consumption does not adversely affect GDP in the short-run but would in the long-run; thus, these countries should adopt a more vigorous energy policy. Furthermore, we broaden the investigation by dividing the sample countries into two cross-regional groups, namely the APEC and ASEAN groups, and even more important results and implications emerge.     

The effect of the Internet on economic growth: Evidence from cross-country panel data

Using cross-country panel data, we found evidence that the Internet plays a positive and significant role in economic growth after investment ratio, government consumption ratio, and inflation were used as control variables in the growth equation.     

Renewable energy innovations in Europe: a dynamic panel data approach

We investigate the determinants of renewable energy R&D intensity and the impact of renewable energy innovations on firm performance, using several dynamic panel data models. We estimate these models using a large data set of European firms from 19 different countries, with some patenting activity in areas related to renewable energies during the 1987 to 2007 period. Our results confirm our priors on the determinants of the rapid development of renewable energy R&D intensity during the past decades. Additionally, we find evidence that renewable patent intensity has a significant dynamic impact on the stock market value of firms.     

Democracy and growth in Africa: Implications of increasing electoral competitiveness

Estimating a 1975–2004 decadal panel data in an augmented production-function framework, the paper finds that indexes of electoral competitiveness exhibit U-shape relationships with GDP growth, implying quite different “intermediate” and “advanced”-level effects of reforms in Africa.     

Economic complexity,human capital and economic growth: empirical research based on cross-country panel data

Economic complexity reflects a country’s production capabilities and plays an important role in economic growth. This article measures the economic complexity of 210 countries using the method of reflections, and investigates the impact of economic complexity and human capital on economic growth. The measurement results show that there are significant differences regarding the level of complexity among countries. High-income economies have higher complexity than low- and middle-income economies. The empirical findings demonstrate that economic complexity and different levels of human capital have positive effects on long- and short-term growth. A positive interaction effect on economic growth exists between economic complexity and human capital. In addition, secondary education as a proxy for human capital has a relatively greater positive direct effect and a much stronger interactive effect with complexity on economic growth. In addition, the magnitude of the interaction effect between economic complexity and human capital on long- and short-term growth increases as the revealed comparative advantage threshold grows.     

On the optimality of public capital for long-run economic growth: evidence from panel data

The role of public capital in economic growth is examined using data from the Penn World Tables and other sources on a large number of countries. Drawing on intertemporal optimization, the theoretical framework nests the exogenous (Solow) and endogenous types of growth and is data-consistent. It is found that public capital makes a significant contribution to growth. The actual level of investment on public capital is suboptimal. Growth in recent decades can be characterized as ‘endogenous’ with little sign of convergence. There is evidence of a growth slow-down between the 1970s and 1980s. Human capital also significantly enhances growth.     

Causal relationship between energy consumption and GDP growth revisited: A dynamic panel data approach

This paper uses the panel data of energy consumption and GDP for 82 countries from 1972 to 2002. Based on the income levels defined by the World Bank, the data are divided into four categories: low income group, lower middle income group, upper middle income group, and high income group. We employ the GMM-SYS approach for the estimation of the panel VAR model in each of the four groups. Afterwards, the causal relationship between energy consumption and economic growth is tested and ascertained. We discover: (a) in the low income group, there exists no causal relationship between energy consumption and economic growth; (b) in the middle income groups (lower and upper middle income groups), economic growth leads energy consumption positively; (c) in the high income group countries, economic growth leads energy consumption negatively. After further in-depth analysis of energy related data, the results indicate that, in the high income group, there is a great environmental improvement as a result of more efficient energy use and reduction in the release of CO₂. However, in the upper middle income group countries, after the energy crisis, the energy efficiency declines and the release of CO₂ rises. Since there is no evidence indicating that energy consumption leads economic growth in any of the four income groups, a stronger energy conservation policy should be pursued in all countries.     

都市圈经济增长的空间相依性研究——基于中国三大都市圈的实证研究

There are a number of theoretical reasons why cities interact with each other. Such spatial interdependence has been largely ignored by the empirical literature with only a couple of recent papers accounting for such issues in their estimation. This paper takes spatial dependence panel data models in specifying and testing to analyze three metropolitan growth behaviors in China. We find that controlling for fixed-effects allows us to disentangle the effect of spatial dependence from that of spatial heterogeneity and that of omitted variables. The estimated relationships of traditional determinants of urbanization are robust to inclusion of terms to capture spatial interdependence, even though such interdependence is estimated to be significant. Additionally, the three metropolitan areas might be said to represent three distinct stages during the urbanization of China.      

Technical efficiency of Spanish manufacturing firms: a panel data approach

This paper estimates the levels of technical efficiency reached by Spanish manufacturing firms, through an econometric estimation of frontier production functions for fifteen sectors of activity, and also, obtains other relevant technological measurements of these productive processes such as the scale and the technical progress parameters. The methodology used is the panel data methods (Schmidt and Sickles, 1984). The statistical source is provided by the Survey on Business Strategies (Encuesta Sobre Estrategias Empresariales), a panel of data covering 855 Spanish manufacturing firms observed over the period 1990-1994. Our econometric results confirm the great heterogeneity in the firms' efficiency, the predominance of constant returns to scale and the great rate of technological progress.     

Inflation and economic growth in Latin America: Some panel time-series evidence

In this paper we investigate the role of macroeconomic performance, mainly in terms of rates of inflation, in determining economic growth in four Latin American countries which suffered hyperinflationary bursts in the 1980s and early 1990s, but that also differ in terms of development levels. The data set covers the period between 1970 and 2007, and the empirical results, based on panel time-series data and analysis, confirm the anecdotal evidence which suggests that inflation has had a detrimental effect to growth in the region. All in all, we highlight the fact that excessive inflation has clearly offset the Mundell–Tobin effect and consequently the high costs that inflation has had on economic activity in the region.     

Temperature,rainfall and economic growth in Africa

Following a recent line of research, this paper investigates the aggregated effects of temperature and rainfall on economic growth in Africa. Our econometric approach is based on a reduced-form model and takes account explicitly of parameter heterogeneity and cross section dependence, relying on ARDL modelling and panel estimators with multifactor structures. We find clear supportive evidence of short- and long-run relations between temperature and per-capita GDP growth, while the role played by rainfall appears to be less important and the evidence on its statistical significance is less clear-cut. Very similar results are reported when the analysis is carried out by focusing solely on Sub-Saharan African countries or considering GDP growth per worker. This evidence is in sharp contrast to the results obtained via standard MG estimation and this confirms that, by not controlling for cross section dependence, traditional panel estimators are likely to provide misleading inference. The empirical results suggest that, far from adapting quickly to weather shocks, African economies appear to be significantly damaged by them. In the absence of corrective measures, the current trends in climate change may impose a progressively heavier burden on African countries.
