Recent empirical studies of firm-level performance have tested complementarity in the case of multiple practices. These papers have drawn conclusions using potentially biased estimates of pair-wise interaction effects. We develop a consistent and simple testing framework and test it against...

We examine the impact of internal and external R&D on labor productivity in a 6-year panel of Dutch manufacturing firms. We apply a dynamic linear panel data model that allows for decreasing or increasing returns to scale in internal and external R&D and for economies of scope. We find...

This study provides an exploratory analysis of differences between family and non-family firms in innovation investment, product and process innovation outcomes, and labor productivity. Using data from the Community Innovation Survey on 2,087 German small- and medium-sized enterprises (SMEs), we...

Following a centuries-long decline in the rate of self-employment, a discontinuity in this downward trend is observed for many advanced economies starting in the 1970s and 1980s. In some countries, the rate of self-employment appears to increase. At the same time, crosssectional analysis shows a...

This note investigates the impact of changes in the number of business owners on three measures of economic performance, viz. employment growth, GDP growth and labor productivity growth. Particular attention is devoted to the lag structure. The analysis is performed at the country level for 21...

This paper investigates time allocation decisions in new ventures of female and male entrepreneurs using a new model that distinguishes between effects of preferences (what they like) and productivity (what they are good at) on the number of working hours. Using data of 1203 entrepreneurs we...

The increased importance of knowledge as a source of competitiveness for modern economies suggests that the organization of industries most conducive to innovative activity and unrestrained competition will be linked to higher growth rates. Entrepreneurial activity is generally assumed to be an...

There are various reasons why some entrepreneurs may be more overoptimistic at the start of their ventures than others. We distinguish between four broad categories of determining factors and three areas of overoptimism (income, psychological burden and leisure time) and empirically investigate...
