Business Groups and Risk Sharing Around the World

No 4446, CEPR Discussion Papers from C.E.P.R. Discussion Papers

Abstract: We use a newly-constructed database on business groups in twelve emerging markets, combined with historical and modern data from Japan, to examine the popular view that business groups ? ubiquitous in most emerging markets ? facilitate risk sharing by smoothing the performance of affiliated firms. We confirm the ?conventional wisdom? on risk sharing by Japanese keiretsu, find evidence of risk sharing in several other countries (e.g. Korea, Thailand), and very limited evidence of ?liquidity smoothing? in one country, India. In most countries, however, our estimates of risk sharing are usually not statistically significant. Tests of two-dimensional first-order-stochastic-dominance suggest that the Japan result ? that group affiliated firms have both lower levels of operating profitability and lower standard deviations of operating profitability ? does not generalize to most emerging markets. We also find no correlation between the extent of capital market development and the nature of the legal system on the one hand, and the extent of risk sharing provided by business groups on the other. The popular view of the importance of risk sharing in business groups is thus not validated by our analysis. With the exception of Japan, other reasons are probably more likely to explain the presence of business groups.
