This study investigates the relationship between labour market externalities and regional growth based on real labour flows. In particular, we test for the importance of labour mobility across so-called skill-related industries. We make use of a sophisticated indicator that measures the degree...

This paper investigates the impact of regional sectoral diversity on regional employment growth in Italy over the period 1991-2001. Assuming that externalities may be stronger between industries selling similar products or sharing the same skills and technology (i.e. related industries), we...

This paper analyzes the effects of the evolution of knowledge base in the manufacturing sectors on regional productivity growth. Knowledge is viewed as a heterogeneous asset, and an evolutionary perspective is adopted. The results of the empirical estimations corroborate the hypothesis that...

This paper makes an attempt to estimate the impact of regional variety and trade linkages on regional economic growth by means of export and import data by Italian province (NUTS 3) and sector (3-digit) for the period 1995-2003. Our results show strong evidence of related variety contributing to...

This paper provides a conceptual discussion of relatedness, which suggests a focus on individuals as a complement to firms and industries. The empirical relevance of the main arguments are tested by estimating the effects of related and unrelated variety in education and occupation among...

Related variety is important to regional growth because it induces knowledge transfer between complementary sectors at the regional level. This is accomplished through three mechanisms: spinoff dynamics, labor mobility and network formation. They transfer knowledge across related sectors, which...

This paper summarizes the theoretical arguments from evolutionary theory and ecological economics to put the trade-off between regional economic diversity and regional economic growth on stronger theoretical foundations. Hypotheses are tested using an empirical model that links regional economic...

This paper employs both the descriptive and comparative approaches and uses the definition of knowledge and knowledge indicators used in the literature to examine the existence and development of the knowledge economy in the Arab region. We fill the gap in the Arab literature and present a more...

In this paper, we use the data from the firm survey (2002) at the micro level and some recent and update current secondary data at the macro level to examine the importance (impacts) of tacit and codified sources of knowledge at firm and aggregate levels respectively. Our results at the macro...

In this paper we provide a new contribution and fill the gap in the Sudanese literature by investigating the importance (impact) of tacit and codified sources of knowledge at the micro and macro levels in Sudan using new primary data from the firm survey (2010) at the micro level and secondary...
