Empirical studies conducted mainly at the country level support the relevance of access to finance as a determinant of entrepreneurship (Kerr and Nanda, 2009). There have been, however, limited efforts at producing sound internationally comparable data on the financing of new and small enterprises. This chapter addresses some of the challenges inherent to collecting statistics on entrepreneurial finance; it focuses, in particular, on data on the demand for finance by young and small enterprises and on the conditions they face in accessing finance. It thus complements the work of Financing SMEs and Entrepreneurs: An OECD Scoreboard (OECD, 2012), which presents national data mainly on the supply side of finance sourced from Central Banks or from surveys of finance suppliers. The Scoreboard also includes demand-side data collected by surveys undertaken by both private and pubic institutions. However, the Scoreboard recognises that improvements are required as concerns demand-side data and encourages international, regional and national authorities as well as business associations to work together to harmonise quantitative demand-side surveys in terms of survey population, questions asked and timeframes.
