What Does China’s Rise in Patents Mean? A Look at Quality vs. Quantity
Zhu, Heting; Santacreu, Ana Maria (2018)
Using three measurements of patent quality, we argue that there is still room for China to improve its innovative activities.

Manufacturing and Service Sector Roles in the Evolution of Innovation and Productivity
Zhu, Heting; Santacreu, Ana Maria (2018)
The relative size of the manufacturing sector in an economy depends on its stage of development. As economies become more industrialized, employment and output increase rapidly.

Zhu, Heting; Vandenbroucke, Guillaume (2018)
In this article, we discuss another facet of the difference between men and women in the labor force: their exposure to unemployment. We complement our analysis with a discussion of the black-white exposure to unemployment and show that it behaves noticeably differently than male-female exposure.
