Venture capital firms use a variety of accumulated resources to inform their investment activities, but do the rely solely on their own resources or do they employ other firms’ resources to complement their own? This column examines the pattern of co-investments among venture capital firms and discusses the economic implications. Past experience of co-investments increases the likelihood of future co-investments among firms when the returns from these past co-investments were high, and also when the jointly invested venture business companies experienced greater growth after an IPO.

Conventional wisdom holds that venture capital-financed start-up companies generate positive spillovers for other businesses, but these spillovers are hard to measure accurately. This column uses a broader analysis of patent spillovers than previous studies to argue that venture capital-financed start-up companies help established companies innovate, and play a significant role in the commercialisation of new technologies. This suggests that subsidies for venture capital investment should be at least as large as current R&D subsidies.

Investment officers are often the highest-paid individuals in institutions such as pension funds and foundations, because of the size and importance of the decisions they make. This column argues that successful investment officers earn their pay, because they make returns that can't be explained by luck alone. Therefore, institutional investors might benefit from investing in high-quality investment officers.


The global financial crisis has had a profound impact on output and productivity in advanced and emerging economies. In response, policymakers around the world have acted boldly with monetary policy, macro-prudential policy and regulation.

Is productivity being held back by financial factors - such as the lack of long term finance for long term investment - or is productivity being held back by real economy factors, such as globalisation and demographics? The recent crisis has also spurred a reassessment of the relationship between the level (and type) of finance and growth. Could weak productivity growth owe in part to wasteful investment spending or an undersupply of financial services? How does the mix of early and late stage financing drive investment and productivity? This conference aims to bring together perspectives on these big questions, as they will provide important guidance for future policy actions.

Small and medium-sized European businesses find it hard to raise capital, especially during their development phase. This column compares the situation in the US and Europe and suggests that many SMEs in Europe still face significant difficulties in identifying and accessing sources of funding. Promoting greater equity involvement and improving access to and information on all of the various funding options would do much to boost growth.

The rapid growth of the US financial sector has driven policy debate on whether it is socially desirable. This column examines the trade-off between finance and entrepreneurship, and links the growth of finance to rising wealth inequality. Although financial intermediation helps allocate capital efficiently, people choosing a career in finance do not internalise the negative effect on the pool of talented entrepreneurs. This mechanism can explain the simultaneous growth of wealth inequality and finance in the US, and why more unequal countries have larger financial sectors.

Do economies’ social policies affect their innovative outcomes? This column uses the case of venture capital investors to argue that it may. Countries that protect workers rather than jobs – and thus avoid employment-protection laws – developed stronger venture-capital markets over 1999-2008, especially in highly volatile sectors like computers or energy.
