Ratio Working Paper No. 230: University Knowledge Spillovers & Regional Start-up Rates

Ladda ner PDF

Sammanfattning

This paper investigates regional start-up rates in the knowledge intensive services and high-tech industries. Integrating insights from economic geography and population ecology into the literature on entrepreneurship, we develop a theoretical framework which captures how both supply- and demand-side factors mold the regional bedrock for start-ups in knowledge intensive industries. Using multi-level data of all knowledge intensive start-ups across 286 Swedish municipalities between 1994 and 2002 we demonstrate how characteristics of the economic and political milieu within each region influence the ratio of firm births. We find that economically affluent regions dominate entrepreneurial activity in terms of firm births, yet a number of much smaller rural regions also revealed high levels of start-ups. Knowledge spillovers from universities and firm R&D strongly affect the start-up rates for both knowledge intensive manufacturing and knowledge intensive services firms. However, the start-up rate of knowledge-intensive service firms is tied more strongly to the supply of highly educated individuals and the political regulatory regime within the municipality. This suggests that knowledge intensive service-start-ups are more susceptible to both demand-side and supply-side context than manufacturing start-ups. Our study contributes to the growing stream of research that explains entrepreneurial activity as shaped by contextual factors, most notably educational institutions that contribute to technology startups.

Educational Management Administration & Leadership

Sammanfattning

We study the effects of principal instructional leadership on pupil educational achievement using longitudinal data of 120,394 teacher responses across 1919 schools in Sweden over 9 years. Through multilevel structural equation modelling, we test how teacher ratings of principal leadership influence indicators of educational achievement and the extent to which this effect is channelled through a collaborative teacher culture in schools. Findings suggest that teacher collaboration partly mediates the relationship between principal instructional leadership and pupil educational achievement in terms of final year grade point average. However, concerning final year standardised test scores, principal instructional leadership alone has a stronger relationship to school performance than teacher collaboration. The longitudinal analysis suggests these patterns are driven by relatively stable differences between schools rather than dynamic changes in schools over time, indicating that variation in school contexts such as culture, organisational structure, and leadership practices persist over time. We discuss implications for research, practice, and policy on school leadership and teacher collaboration.

Journal of Business Venturing

Sammanfattning

Boards are a vital resource for early-stage ventures, offering advice, funding connections, and strategic guidance — especially when directors bring diverse expertise. Yet, as ventures grow and succeed, that diversity can erode. Our study of over 28,000 Swedish ownermanaged firms shows that directors whose expertise differs from that of the founder(s) are more likely to leave—not during hardship, but when the business is performing well. Interviews with several founders and directors further suggest that as ventures mature, they increasingly rely on internal capabilities and shift toward boards that reflect the founder’s evolving preferences. These dynamics lead to more homogenous boards over time, potentially narrowing the range of perspectives available in the board. For founders and policymakers, the findings highlight a key challenge: keeping diverse directors around not just at the start, but as the company scales.

Stockholm School of Economics Working Paper series

Sammanfattning

Vi undersöker hur bostadsområdes- respektive skolegenskaper samvarierar med skolvåld i alla svenska gymnasieskolor under en 15-årsperiod.

Vi visar att ungdomars narkotikabrottslighet (bostadsområdesnivå) och läraromsättning (skolnivå) är centrala drivkrafter för skolvåld över geografiska områden.

Andra prediktorer är kontextspecifika: skolfaktorer såsom meritvärde (genomsnittsbetyg) och skolavhopp är huvudsakligen associerade med skolvåld i storstadsområden, medan socioekonomiska indikatorer i bostadsområden – såsom bostadsförhållanden, socialtjänststöd och arbetslöshet – är mer framträdande i icke-storstadsområden.

Överlag dominerar faktorer på bostadsområdesnivå som förklaring till variationer i skolvåld (ca 40%), jämfört med skolnivå (ca 10%).

Dessa resultat stödjer teorier om strukturell utsatthet som förklaring till skolvåld men ifrågasätter samtidigt dess stadscentrerade fokus, vilket tyder på att social isolering och institutionell fragmentering kan fungera på olika sätt i olika geografiska kontexter.

Vi diskuterar implikationer för forskning och beslutsfattare.
