I develop a theoretical model to examine the effect of capital requirements on risk taking and market structure of banks. Within a portfolio choice model, I allow for heterogeneous productivity among banks and consider the simultaneous capital regulation with a leverage ratio and a risk-weighted...

Supersedes Working Paper 17-17 Fintech has been playing an increasing role in shaping financial and banking landscapes. In this paper, we use account-level data from LendingClub and Y-14M data reported by U.S. banks with assets over $50 billion to examine whether the fintech lending platform...

The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the banking sector. Our main result is that the bail-out policy unambiguously...

We use unique data on banks' private risk assessments of corporate borrowers to quantify how competition among banks affect the risk sensitivity of interest rates in the Norwegian credit market. We show that an increase in competition makes corporate lending rates less sensitive to banks' own...

We document that the dispersion of failure risk across banks within a given region in the U.S. is greater in regions that have higher income inequality. We explain this pattern with a model based on risk shifting incentives where banks issue insured deposits and choose the riskiness of their...

We estimate a dynamic banking model to quantify the impact of a central bank digital currency (CBDC) on the banking system. Our counterfactuals show that a one-dollar introduction of CBDC replaces bank deposits by around 80 cents on the margin. Bank lending falls by one-fourth of the drop in...

In the present work we study asymptotic dynamics of a multi-dimensional piecewise smooth map which models an oligopoly market where competitors use adaptive scheme for reaction choice. Each competitor also defines the moment for renewing the capital equipment depending on how intensively the...

This paper questions the existing notion of competition prevalent in economic theory. It is shown that the prevalent idea of competition is incompatible with economic development. Fair competition, this paper argues, ought to be understood in context. The paper ends by providing some preliminary...

The paper studies a market of horizontally differentiated good under increasing return to scale and exogenous number of firms. Three concepts of equilibria are compared: Cournot, Bertrand and monopolistic competition. Under fairly general assumptions on consumer's preferences, it is shown that...
