We study the behaviour of banking intermediaries focusing on the joint relationships among risk management, fragility and the market structure. Theoretically, we use the industrial organisation approach to analyse the relationships between banking behaviour and risk management goals and between banking behaviour and regulation effects. We develop and calibrate models to study the monopolistic competition effects on banking stability and to study the effects of asset and liability uncertainty on banking decisions. We extend such analyses to study the effects caused by portfolio restrictions and deposit interest-rate regulations on banking behaviour. Empirically, we characterise the financial and banking stylised facts associated to stable and unstable banking systems. Furthermore, we assess among competing theories and policy views regarding the relationships between banking stability and management practices, and between fragility and banking market structure. The empirical study relies on OLS regressions and random effects logit models for panel data. The dataset includes data for a sample of 47 countries during the period 1990-1997.

Theoretically, we show that the optimal risk management asset allocation for banking firms depends on the banking market structure. We also show that the maximisation of long-term profits and the minimisation of financial distress are complementary and compatible management objectives. Furthermore, our findings suggest that the achievement of banking and regulatory goals may depend on the degree of competition in the banking market. Moreover, they also suggest that interest-rate instruments may be better than asset portfolio restrictions as regulatory devices. Empirically, our findings suggest that financial development is associated with market-based financial systems and non-competitive banking systems. We also provide evidence that banking competition enhances fragility. Furthermore, the analyses reject the bank-based policy view regarding the relationship between financial system and banking stability. Hence, the use of derivatives and cross-sectional risk sharing techniques might encourage stability.
