This paper pilots an approach for using trademark data to study regional diversification. Bridging the respective literatures, we develop a regional trademarking-intensity measure that can shed new light on how different regions diversify while also accounting for changing industrial structures and income levels (regional gross domestic product). The approach reveals that density has a moderate effect on trademarking intensity and confirms the strong relationship between new firm formation and regional diversification. These effects are found to vary by sector and to be sensitive to industry-level employment and turnover. Lastly, the analysis indicates that regional diversification differs sharply between urban and peripheral regions. [ABSTRACT FROM AUTHOR]

We study intergenerational social mobility in Mexico at the subnational level to determine whether poorer regions have similar rates of social mobility as richer ones. We approximate socioeconomic status with an index that captures the variability across households in durable goods, services and education of household heads for both adult children and their parents. The estimated indicators suggest a clear north–south gradient in social mobility: the children of poor parents in the northern regions experience greater upward mobility than in the central and southern regions.

Worldwide, city-regions have been considered as locomotors to promote regional and national competitiveness. This normative view has continuously highlighted the significant role of a city within and beyond a region, as it tends to overlook the nature of that city-region, which has been shaped by both its urban and rural settings. To reposition the rural in city-regionalism, this research uses the city-regional policy of Taiwan and its cultural capital, Tainan City, as a case study to reveal the significance that a rural industry can have within and beyond a city-region through adopting a locally based, multiplex city-regional functional approach.
