We develop a general equilibrium model of banks' capital structure, featuring heterogeneous portfolio risk and an imperfectly elastic supply of bank equity stemming from financial market segmentation. In our model, equity is costly and serves as a buffer against insolvency. Banks are ex-ante...

We describe a model in which bank deposits yield liquidity services and therefore earn a lower rate of return than equity. In this sense, deposits are a cheaper source of funding for banks than equity. The banks' equilibrium capital structure is determined by a trade off between the funding...

We examine the pervasive view that "equity is expensive" which leads to claims that high capital requirements are costly for society and would affect credit markets adversely. We find that arguments made to support this view are fallacious, irrelevant to the policy debate by confusing private...

This paper identifies the main dimensions of capital regulation. We use survey data from 142 countries from the World Bank’s (2013) database covering various aspects of bank regulation. Using multiple explorative factor analysis, we identify two main dimensions of capital regulation:...

This paper proposes a new regulatory approach that implements capital requirements contingent on managerial compensation. We argue that excessive risk taking in the financial sector originates from the shareholder moral hazard created by government guarantees rather than from corporate...

This paper proposes a new regulatory approach that implements capital requirements contingent on executive incentive schemes. We argue that excessive risk-taking in the financial sector originates from the shareholder moral hazard created by government guarantees rather than from corporate...

The Basel I Accord introduced a discontinuity in required capital for undrawn credit commitments. While banks had to set aside capital when they extended commitments with maturities in excess of one year, short-term commitments were not subject to a capital requirement. The Basel II Accord...

This paper analyses banks' ability to use capital buffers in the euro area, taking into account overlapping capital requirements between the risk-based capital framework and the leverage ratio capital framework from 2016 to 2022. This analysis is the first to quantify buffer usability in...

After the destructive impact of the global financial crisis of 2008, many believe that pre-crisis financial market regulation did not take the "big picture" of the system suffciently into account and, subsequently, financial supervision mainly "missed the forest for the trees". As a result, the...
