This paper briefly reviews the contemporary literature on relationship banking. We start out with a discussion of the raison d'être of banks in the context of the financial intermediation literature. From there we discuss how relationship banking fits into the core economic services provided by banks and point at its costs and benefits. This leads to an examination of the interrelationship between the competitive environment and relationship banking as well as a discussion of the empirical evidence.

This paper analyzes the optimality of conglomeration. We show that the potential benefits of conglomeration depend critically on the effectiveness of market discipline for stand-alone activities. Effective market discipline reduces the benefits of conglomeration. With ineffective market discipline of stand-alone activities, conglomeration would further undermine market discipline, but may nevertheless be beneficial. In particular, when rents are not too high, the diversification benefits of conglomeration dominate the negative incentive effects. A more competitive environment therefore induces conglomeration. We also show that introducing internal cost-of-capital allocation schemes creates internal market discipline that complements the weak external market discipline of a conglomerate. Our analysis sheds light on the Barings debacle and other recent developments in the banking sector. Journal of Economic Literature Classification Numbers: G20, G21, G34.
