Jean Gadrey et al., « Productivity, Innovation and Knowledge in Services: New Economic and Socio-economic Approaches », HAL-SHS : économie et finance, ID : 10670/1.em9vya
Services now account for almost three quarters of economic activity in advanced market economies and two of the principal topics that researchers on services have been concerned with are, on the one hand, productivity, and on the other, innovation in and through services. These two issues, and finding ways to measure and conceptualize them, lie at the heart of this book.
