We propose a simple network–based methodology for ranking systemically important financial institutions. We view the risks of firms –including both the financial sector and the real economy– as a network with nodes representing the volatility shocks. The metric for the connections of the...

CoCo’s (contingent convertible capital) are designed to convert from debt to equity when banks need it most. Using a Diamond-Dybvig model cast in a global games framework, we show that while the CoCo conversion of the issuing bank may bring the bank back into compliance with capital...

In this paper, we develop a new capital adequacy buffer model (CABM) which is sensitive to dynamic economic circumstances. The model, which measures additional bank capital required to compensate for fluctuating credit risk, is a novel combination of the Merton structural model which measures...

During the Global Financial Crisis, regulators imposed short-selling bans to protect financial institutions. The rationale behind the bans was that “bear raids”, driven by short-sellers, would increase the individual and systemic risk of financial institutions, especially for institutions...

This survey reviews the literature on the political economy of financial structure, broadly defined to include the size of capital markets and banking systems as well as the distribution of access to external finance across firms.The theoretical literature on the institutional basis for...

While financial liberalization has in general favorable effects, reforms in countries with poor regulation is often followed by financial crises. We explain this variation as the outcome of lobbying interests capturing the reform process. Even after liberalization, market investors must rely on...

We investigate the effect of model specification on the aggregation of (correlated) market and credit risk. We focus on the functional form linking systematic credit risk drivers to default probabilities. Examples include the normal based probit link function for typical structural models, or...

We develop a model of endogenous lobby formation in which wealth inequalityand political accountability undermine entry and financial development. In-cumbents seek a low level of effective investor protection to prevent potentialentrants from raising capital. They succeed because they can...

This survey reviews how a recent political economy literature helps explaining variation in governance, competition, funding composition and access to credit. Evolution in political institutions can account for financial evolution, and appear critical to explain rapid changes in financial...

Entry requires external finance, especially for less wealthy entrepreneurs, so poor investor protection limits competition. We model how incumbents lobby harder to block access to finance to entrants when politicians are less accountable to voters. In a broad cross-section of countries and...
