Nascent entrepreneurship and new business ownership are subsequent stages in the entrepreneurial process. We illustrate how information from the largest internationally harmonized database on entrepreneurship, the Global Entrepreneurship Monitor project, can be used to approximate the entrepreneurial process. We make a methodological contribution by computing the ratio of new business ownership to nascent entrepreneurship in a way that reflects the transition from nascent to new business ownership and provides cross-nationally comparable information on the efficiency of the entrepreneurial process for 48 countries. We report evidence for the validity of the transition ratio by benchmarking it against transition rates obtained from longitudinal studies and by correlating it with commonly used entrepreneurship indicators and macro-level economic indices. The transition ratio enables future cross-national research on the entrepreneurial process by providing a reliable and valid indicator for one key transition in this process.  相似文献

Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developing countries where livestock production is still mostly subsistence-oriented and livestock fulfil manifold functions a considerable number of livestock breeding programs have failed. The development of adequate tools to characterise these functions, bearing in mind that these are expressed only rarely in properly functioning markets, is therefore important.This paper seeks to advance the application of such methodologies to the smallholder pig sector in Vietnam. A choice experiment was applied across 140 households involved in pig breeding in order to assess farmers' preferences and the trade-offs for a list of adaptive and productive traits. These included growth, reproduction, disease resistance, feed requirements and appearance.The findings indicate that smallholders highly value both adaptive and performance traits, particularly in resource-driven (i.e. subsistence) production systems. Performance traits were more highly valued in the demand-driven (i.e. market-oriented) systems. These findings have implications for breeding program breed choice and breeding objectives.  相似文献

This paper investigates the direct and indirect impact of works councils via further training on job satisfaction. Basic estimates on an individual level do not reveal clearly direct effects, but on an establishment level, the existence of a works council increases the average job satisfaction. We also find a positive, weakly significant effect on an individual level accompanied by training under instrumental variables estimation and if we control for personal characteristics.  相似文献

This paper provides a Kaldorian interpretation for empiricalregularities of productivity growth at the sectoral level ofthe economy. The statistical evidence is based on a datasetdrawn from internationally compatible time series for employmentand value added in 30 developing countries. Based on novel non-linearstatistical techniques the findings show: (i) a regular patternof positive sectoral employment elasticities with respect tooutput growth; (ii) robust differences across sectors in themagnitude of the employment elasticities; and (iii) employmentelasticities for all sectors that are significantly less thanunity, suggesting strong evidence for increasing returns atthe sector level of the economy.  相似文献
