It is often claimed that small and young firms account for a disproportionately large share of net employment growth. We conduct a meta-analysis of the empirical evidence regarding whether net employment growth rather is generated by a few rapidly growing firms-so-called Gazelles-that are not necessarily small and young. Gazelles are found to be outstanding job creators. They create all or a large share of new net jobs. On average, Gazelles are younger and smaller than other firms, but it is young age more than small size that is associated with rapid growth. Gazelles exist in all industries. They seem not to be overrepresented in high-technology industries, but there is some evidence that they are overrepresented in services.

A number of cross-country comparisons do not find a robust negative relationship between government size and economic growth. In part this may reflect the prediction in economic theory that a negative relationship should exist primarily for rich countries with large public sectors. In this paper an econometric panel study is conducted on a sample of rich countries covering the 1970-95 period. Extended extreme bounds analyses are reported based on a regression model that tackles a number of econometric issues. Our general finding is that the more econometric problems are addressed, the more robust the relationship between government size and economic growth appears. Our most complete specifications are robust even according to the stringent extreme bounds criterion.JEL Classification: E62, H20, H50, O23, O40. * We are grateful for excellent research assistance from Per Thulin and for useful comments and suggestions from Ulf Jakobsson, Assar Lindbeck, Erik Mellander, Joakim Persson and two anonymous referees.

Entrepreneurship policy mainly aims to promote innovative Schumpeterian entrepreneurship. However, the rate of entrepreneurship is commonly proxied using quantity-based metrics, such as small business activity, the self-employment rate, or the number of startups. We argue that those metrics give rise to misleading inferences regarding high-impact Schumpeterian entrepreneurship. To unambiguously identify high-impact entrepreneurs we focus on self-made billionaires (in US dollars) who appear on Forbes Magazine's list and who became wealthy by founding new firms. We identify 996 such billionaire entrepreneurs in 50 countries in 1996-2010, a systematic cross-country study of billionaire entrepreneurs. The rate of billionaire entrepreneurs correlates negatively with self-employment, small business ownership, and firm startup rates. Countries with higher income, higher trust, lower taxes, more venture capital investment, and lower regulatory burdens have higher billionaire entrepreneurship rates but less self-employment. Despite its limitations, the number of billionaire entrepreneurs appears to be a plausible cross-country measure of Schumpeterian entrepreneurship.

Abstract: In order to get a more complete picture of how labor supply is affected by economic incentives, the effects on absenteeism and not just on contracted hours should be taken into account. Terms of use: Documents in EconStor mayIn particular, absenteeism due to sick leave can be considerable. In this paper we examine whether the level of sick leave compensation affects sick leave behavior. Using time-series data for Sweden spanning a long period with numerous changes of the compensation level, we generally find strong effects of the expected sign. Reforms implying more generous compensation for sick leave tend to be associated with permanent increases in total sick leave per person employed and vice versa. These findings are reinforced in a panel study covering the 1983-91 period.JEL Classification: H55, I38, J22.

Terms of use: Documents in AbstractGuided by a simple theory of task assignment and time allocation, we investigate the long run response to national differences in tax rates on labor income, payrolls and consumption. The theory implies that higher tax rates reduce work time in the market sector, increase the size of the shadow economy, alter the industry mix of market activity, and twist labor demand in a way that amplifies negative effects on market work and concentrates effects on the less skilled.We also describe conditions whereby cross-country OLS regressions yield unbiased estimates of the total effect of taxes, inclusive of indirect effects that work through government spending responses to tax revenues. Regressions on rich-country samples in the mid 1990s indicate that a unit standard deviation tax rate difference of 12.8 percentage points leads to 122 fewer market work hours per adult per year, a drop of 4.9 percentage points in the employment-population ratio, and a rise in the shadow economy equal to 3.8 percent of GDP. It also leads to 10 to 30 percent lower employment and value added shares in (a) retail trade and repairs, (b) eating, drinking and lodging, and (c) a broader industry group that includes wholesale and motor trade.JEL Classification: D13, H24, J22

Entrepreneurship is largely ignored or treated in a highly simplified way in endogenous growth theory. Still, it is now widely recognized that the supply of entrepreneurial talent is likely to be important for economic growth, innovation and job creation. This study consists of an indepth examination of how the supply of productive entrepreneurship is likely to be affected by the kind of tax and welfare arrangements that may prevail in a mature welfare state. Sweden, allegedly the most extensive of all welfare states, is the object of the empirical analysis. It is shown how key welfare state institutions tend to reduce economic incentives both for opportunity-based and necessity entrepreneurship. Both aggregate economic performance and data on firm growth and direct measures of entrepreneurial activity are broadly consistent with the identified structure of payoffs. A number of measures can be implemented to strengthen entrepreneurial incentives within extensive welfare states, but the fact still remains that an entrepreneurial culture and a welfare state are very remotely related. As a result, the respective cultures are unlikely to be promoted by a similar set of institutions.JEL Classification: M13; J20; H30; O12.
