Expert Political Risk Opinions and Banking System Returns: a Revised Banking Market Model
نویسنده
چکیده
Human behavior in banking and financial systems is in part made up of a complex mix of political, social and cultural factors. These factors are reflected in expert opinion based political risk scores. Market inefficiency is largely a result of anomalies in human behavior causing information asymmetries. A basic systemic market model is re-specified into a model for international banking systems, which controls for pure political risk. Samples of developed and developing banking systems are examined. Political risk factors and world banking returns are exogenous in models of countrybanking system returns. New political information assists in explaining banking system stock returns. The findings should be of interest to investors in banking stocks. Banking regulators may be assisted in decisions on appropriate levels of regulatory capital as a benchmark for banking systems. The model could help to anticipate financial crises. JEL Classification: F36
