Abstract: We show how banks’ excessive risk-taking, stemming from
informational asymmetries in loan markets, can lead to an excessive output
loss when a recession starts. Risk-based capital requirements can alleviate
the output loss by reducing excessive risk-taking in ‘normal’ times. Model
simulations suggest that the differentiation of risk-weights in the Basel
framework might be further increased in order to take full advantage of the
allocational effects of capital requirements. Our analysis also provides a
new rationale for the countercyclical elements of capital requirements.
