The Entrepreneurial Adjustment Process in Disequilibrium: Entry and Exit when Markets Under and Over Shoot

The main contribution of entrepreneurship theory to economics is to provide an account of market performance in disequilibrium but little empirical research has examined firm entry and exit in this context. We redress this by modelling the interrelationship between firm entry and exit in disequilibrium. Introducing a new methodology we investigate whether this interrelationship differs between market 'undershooting' (the actual number of firms is below the equilibrium number) and 'overshooting' (vice versa). We find that equilibrium-restoring mechanisms are faster in over than in undershoots. The results imply that in undershoots a lack of competition between incumbent firms contributes to restoration of equilibrium (creating room for new-firm entry) while in overshoots competition induced by new firms (in particular strong displacement) helps restore equilibrium.entry, exit, equilibrium, industrial organization, undershooting, overshooting

Export-Driven New Ventures and Economic Growth

In this paper the relationship between a country's prevalence of new ventures and its rate of economic growth is investigated, while distinguishing between export-oriented new ventures and domestic new ventures. It is generally acknowledged that new venture creation as well as export activity may both be important strategies for achieving national economic growth. However, to our knowledge no attempt has been made to empirically investigate the role of export-driven new ventures in economic growth. We focus on the national level and use data for a sample of 36 countries that participated in the Global Entrepreneurship Monitor in 2002. Our results suggest that a country's prevalence of export-driven new ventures is significantly positively related to economic growth, whereas the prevalence of new ventures that focus exclusively on domestic market sales shows no significant relation to national growth.entrepreneurship, export, international new ventures, economic growth, Global Entrepreneurship Monitor

The Long Persistence of Regional Entrepreneurship Culture: Germany 1925-2005

We investigate the persistence of levels of self-employment and new business formation in different time periods and under different framework conditions. The analysis shows that high levels of regional self-employment and new business formation tend to be persistent for periods as long as 80 years and that such an entrepreneurial culture can even survive abrupt and drastic changes in the politic-economic environment. We thus conclude that regional entrepreneurship cultures do exist and that they have long-lasting effects

Knowledge Spillovers and Economic Growth

The importance of knowledge spillovers for achieving innovation and economic growth is widely recognized. It is not straightforward which type of spillovers is most effective: intra-sectoral spillovers or inter-sectoral spillovers. We investigate this controversy using a model of regional growth. The model also deals with the impact of local competition on innovation and growth. The model is estimated using sectoral data for 40 Dutch regions in the period 1987-1995. We find that local competition is important particularly for economic growth in industry sectors (manufacturing and construction), while diversity, a proxy for inter-sectoral spillovers, is important particularly for growth in service sectors. We find no effect for specialization (a proxy for intra-sectoral spillovers).knowledge spillovers; innovation; economic growth; industry structure

The Relationship between Firm Births and Job Creation

This paper examines the relationship between firm births and job creation in Great Britain. We use a new data set for 60 British regions, covering the whole of Great Britain, between 1980 and 1998. The central theme of the paper is that, with the exception of a recent paper by Audretsch and Fritsch for Germany, the relationship between new-firm startups and employment growth has previously been examined either with no time-lag or with only a short period lag. The current paper examines short-run as well as long-run relationships and provides results for Great Britain similar to those for Germany. We find that the short-run employment impact of new-firm startups in British regions has been bigger in the 1990s compared to the 1980s. Concerning long-run effects, we find that the employment impact of new-firm startups is strongest after about five years, but the effect disappears after a decade.new-firm startups; employment growth; entrepreneurship; Great Britain.

The Relationship between Entrepreneurship and Unemployment in Japan

This paper examines the relationship between entrepreneurship (as measured by fluctuations in the business ownership rate) and unemployment in Japan for the period between 1972 and 2002. We find that, although Japan’s unemployment rate has been influenced by specific exogenous shocks, the effects of entrepreneurship on unemployment are not different when compared to other OECD countries. In the past, small firms in Japan benefited from the protective environment of the keiretsu structure. This secure environment no longer exists, and a new market environment conducive to new venture creation and growth has not yet been established. We argue that the Japanese government should actively stimulate an entrepreneurial culture.entrepreneurship; business ownership; unemployment; Japan

Designing environmental uncertainty information for experts and non‐experts: does data presentation affect users' decisions and interpretations?

Uncertainty information in natural hazard forecasts is increasingly being explicitly communicated. This study was designed to determine whether different ways of communicating uncertainty graphically affects decisions and interpretations of forecasts and whether expertise was a factor in decisions and interpretations from forecasts explicitly showing uncertainty. In a hypothetical decision-making task regarding ice thickness and shipping, 138 experts and non-experts received ice-thickness forecasts in four different presentations expressing uncertainty: worded probability, spaghetti plot, fan plot, and box plot. These forecasts contained no measures of central tendency. There was no consistent difference in decision or best-guess forecast (deterministic ice thickness forecast based on the forecast representation) between the different forecast representations. However, participants interpreted different amounts of uncertainty across the different forecast representations. Experts made significantly more economically rational decisions than non-experts, interpreted lower best-guess forecasts, and inferred significantly more uncertainty than nonexperts. These results suggest that care be taken in choosing how uncertainty is represented in forecasts, especially between expert and non-expert audiences
