The development of the small and medium enterprise sector is deemed crucial for economic growth and poverty alleviation. Such firms are often though to be at a disadvantage when compared with larger enterprises, but the reverse can apply, for example in the more flexible approach of the smaller firm. This paper draws on a private sector survey in 80 countries examining whether business obstacles are related to firm size. It finds a bias against small firms, which experience significantly greater problems than large firms with financing, taxes and regulations, inflation, corruption and street crime. These problems should be the prime targets of policies aimed at reducing inequity.

"The authors test competing theories of capital structure choices using firm-level data on firm borrowings. The majority of firms in the dataset are privately owned, young, micro or small and medium enterprise (SME) firms concentrated in the service sector. In general, the financing pattern of firms is low leverage ratios and, in particular, low levels of intermediated financing and long-term financing. Average firm growth rates decreased during the five years of the sample period. Average profitability growth ratios are also negative across age and sectors and large firms have the highest negative profit growth rates. Statistical tests find a positive firm size effect on financial intermediation. Larger firms have higher leverage ratios (both short term and long term), including higher use of trade credit. There is also a negative influence of profitability on leverage ratios (more profitable firms use less external financing), which supports the "pecking order" theory that in environments with greater asymmetric information (such as weaker credit information) firms prefer to use internal or inter-firm financing. Finally, firms operating in a competitive environment have higher leverage ratios. For instance, young, small firms are the most active employment generators in the Polish economy. In particular, the authors find that although SMEs seem to be very active in creating jobs in recent years. This suggests that a new type of firm is emerging that is more market and profit-oriented. But at the same time, these firms appear to have financial constraints that impede their growth. Improvements in the business environment, such as better credit and registry information, could help promote growth in this sector. "--World Bank web site.

This paper investigates the economic rationale for intervention in support of small and medium scale enterprises, on both theoretical and empirical grounds. It argues that the justification for SME interventions lies in market and institutional failures that bias the size distribution of firms, rather than on any inherent economic benefits provided by small firms. The role of the state is mainly to provide an enabling business environment that opens access to markets and reduces policy-induced biases against small firms. Governments can accelerate the development of markets for financial and non-financial services suited to SMEs by promoting innovation in products and delivery mechanisms, and by building institutional capacity. Improving the development impact of SME strategies will require much more attention to the monitoring and evaluation of intervention outcomes.

measure of the rate of innovation --research-and-development (R&D) expenditure per employee compared to new patents received per employee -- does not adequately capture a unique feature of SMEs, namely that owners and managers are often themselves innovators. For example, in Japan 52 per cent of SMEs' innovations reported in 1986 were created by employers, whereas in large firms 72 per cent of innovations were created by research technicians. Nevertheless, patchy evidence from Germany, the United Kingdom and the United States indicates that SMEs at least hold their own in terms of innovation compared to large firms. Perhaps most significantly, a recent study indicates that, while the total number of innovations is positively related to R&D expenditures, skilled labour and the degree to which large firms comprise the industry, in innovative industries innovative activity tends to emanate more from SMEs than large firms. This is probably because in industries where large firms dominate, SMEs need to be innovative to survive. There is much information to suggest that in technologies such as micro-electronics, new materials and biotechnology SMEs tend to be in the vanguard of innovation. Small and medium-sized enterprises as exporters. The contribution of SMEs to a national economy from exporting is generally small; for example, in Japan SMEs accounted for only 13 per cent of merchandise exports in 1990.

The book provides a comprehensive examination of patterns and determinants of production networks in East Asia, a key driver in the region’s global success. It provides the reader with an accessible understanding of the theoretical literature on production networks and recent developments in empirical analysis at the industry and firm-levels. The topics covered in the book include: gross trade in parts and components and gravity models, trade in value added, industry case studies, and micro data econometric studies of firm heterogeneity in production networks. The micro data econometric studies explore key aspects of the heterogeneity of firms in East Asian production networks such as technological capability, the entry of small and medium enterprises into production networks, business use of free trade agreements, and access to credit. Blending new sources of data, empirical tools and econometric methods this book is highly recommended for readers who seek to understand the workings of the complex web of production networks in East Asia.

This book analyzes why some dictators find it in their self-interest to curb corruption.

Are Small Firms Important? Their Role and Impact proposes and supports the claim that small firms make two indispensable contributions to the economy. First, they are an integral part of the renewal process that pervades market economies. New and small firms play a crucial role in experimentation and innovation that leads to technological change, productivity and economic growth. Second, small firms are the essential mechanism by which millions enter the economic and social mainstream of American society. The public policy implications for sustained economic growth and social well-being is the continued high-level creation of new and small firms by all segments of society. It should be the role of government policy to facilitate that process by eliminating entry barriers, lowering transaction costs, and minimizing regulation.
