世界経済・社会統計 = World development indicators

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

Although institutional reforms are necessary to increase rates of entrepreneurship in European countries, we argue that one-size-fits-all reform strategies are unlikely to be successful. Reform strategies must be informed by a better knowledge of the varieties of European capitalism and the institutional complementarities that drive these differences. We investigate these issues by gathering a number of potentially relevant entrepreneurial regime measurements as well as indicators of formal and informal institutions based on data available from the 2000s onward. We employ principal component analysis, factor analysis and cluster analysis to examine how 21 European countries and the United States cluster in the entrepreneurial and institutional dimensions. Our results reveal six country clusters, or entrepreneurial regimes, with a distinct bundle of entrepreneurial characteristics and institutional attributes. The main implication is that different reform strategies are appropriate to promote entrepreneurship and economic growth in European countries in different clusters.

The Diversity of Entrepreneurial Regimes in Europe

It is frequently argued that policymakers should target high-tech firms, i.e., firms with high R&D intensity, because such firms are considered more innovative and therefore potential fast-growers. This argument relies on the assumption that the association among high-tech status, innovativeness and growth is actually positive. We examine this assumption by studying the industry distribution of high-growth firms (HGFs) across all 4-digit NACE industries, using data covering all limited liability firms in Sweden during the period 1997–2008. The results of fractional logit regressions indicate that industries with high R&D intensity, ceteris paribus, can be expected to have a lower share of HGFs than can industries with lower R&D intensity. The findings cast doubt on the wisdom of targeting R&D industries or subsidizing R&D to promote firm growth. In contrast, we find that HGFs are overrepresented in knowledge-intensive service industries, i.e., service industries with a high share of human capital.

Are High-Growth Firms Overrepresented in High-Tech Industries?

It is well-known that men and women differ in their views regarding the severity of climate change, but do they also differ in their support for climate policy and in undertaking climate action in their everyday lives? Previous survey evidence on these questions is inconclusive, but we can answer them using unique survey data from the Swedish Environmental Protection Agency (SEPA). Regression analysis confirms that Swedish women believe more strongly than men that climate change will affect Sweden. Furthermore, women engage in more climate-mitigating behavior than men, even conditional on climate beliefs. The association between gender and climate policy support is less robust, and disappears altogether when climate beliefs are controlled for, demonstrating that climate beliefs are the main mechanism explaining the relationship between gender and policy support.

Gender and climate action

Previous examinations of the literature suggests that high-growth firms (HGFs) exist in all or most industries, are not overrepresented in high-tech, and if anything appear to be slightly overrepresented in services In an updated overview, we find that more recent studies, employing better statistical methods, show a clear link between technological sophistication and HGFs In a tobit model we examine what factors explain the presence of HGFs across 5-digit-NACE-industries in Sweden 1997-2005 We find that technological sophistication is crucial for the prevalence of HGFs in an industry, particularly in services These results are in line with both current research and previous research concerning Sweden We conclude that innovation is crucial for firm growth

Industrial variation of high-growth firms

We demonstrate how successful entrepreneurship depends on a collaborative innovation bloc (CIB), a system of innovation that evolves spontaneously and within which activity takes place through time. A CIB consists of six pools of economic skills from which people are drawn or recruited to form part of a collaborative team, which is necessary for innovation-based venturing to flourish. The six pools include entrepreneurs, inventors, early- and later-stage financiers, key personnel, and customers. We show how the application of the CIB perspective can help make institutional and evolutionary economics more concrete, relevant, and persuasive, especially regarding institutional prescriptions. Generally, we envision an institutional framework that improves the antifragility of CIBs and the economic system as a whole, thus enabling individual CIBs and the broader economic system to thrive when faced with adversity.
