This paper presents recent research on access to finance by small and medium-size enterprises (SMEs). SMEs form a large part of private sector in many developed and developing countries. While cross-country research sheds doubt on a causal link between SMEs and economic development, there is substantial evidence that small firms face larger growth constraints and have less access to formal sources of external finance, potentially explaining the lack of SMEs’ contribution to growth. Financial and institutional development helps alleviate SMEs’ growth constraints and increase their access to external finance and thus levels the playing field between firms of different sizes. Specific financing tools such as leasing and factoring can be useful in facilitating greater access to finance even in the absence of well-developed institutions, as can systems of credit information sharing and a more competitive banking structure.

Motivated by public policy debates about bank consolidation and conflicting theoretical predictions about the relationship between bank concentration, bank competition and banking system fragility, this paper studies the impact of national bank concentration, bank regulations, and national institutions on the likelihood of a country suffering a systemic banking crisis. Using data on 69 countries from 1980 to 1997, we find that crises are less likely in economies with more concentrated banking systems even after controlling for differences in commercial bank regulatory policies, national institutions affecting competition, macroeconomic conditions, and shocks to the economy. Furthermore, the data indicate that regulatory policies and institutions that thwart competition are associated with greater banking system fragility.

Theory does not predict an unambiguous relationship between a country’s financial and legal institutions and firm size. Using data on the largest industrial firms for 44 countries, we find that firm size is positively related to financial intermediary development, the efficiency of the legal system and property rights protection. We do not find any evidence that firms are larger in order to internalize the functions of the banking system or to compensate for the general inefficiency of the legal system.
