The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50% of variation in exports is along the extensive...

This paper analyses the relation between competition and concentration in the banking sector. The empirical answer is given by testing a monopolistic competition model of bank branching behaviour on individual bank data at county level (départements and provinces) in France and Italy. We...

This paper studies the relationship between competition measures at the bank level and the price of credit for non-financial firms in Mexico during 2009-2016. Two indicators of competition are constructed: the Lerner indicator and the Boone indicator. Evidence is provided that similar loans...

This paper studies the links between competition in the lending market and spreads of bank loans in Brazil. Evidence from a dataset of more than 13 million loan-level observations from private banks shows a positive relationship between market power, measured by the Lerner index, and the cost of...

The latest global financial and economic crisis reignited the debate on the costs and benefits of foreign bank presence. While discussions on the optimal financing model of foreign owned banks are ongoing, the consensus on the benefits of foreign banks presence is not a matter of dispute. Given...

The conventional paradigm about development banks is that these institutions exist to target well-identified market failures. However, market failures are not directly observable and can only be ascertained with a suitable learning process. Hence, the question is how do the policymakers know...

The fact that money, banking, and financial markets interact in important ways seems self-evident. The theoretical nature of this interaction, however, has not been fully explored. To this end, we integrate the Diamond (1997) model of banking and financial markets with the Lagos and Wright...

Financial network structure is an important determinant of systemic risk. This paper examines how the U.S. interbank network evolved over a long and important period that included two key events: the founding of the Federal Reserve and the Great Depression. Banks established connections to...

The Lerner index is widely used to assess firms' market power. However, estimation and interpretation present several challenges, especially for banks, which tend to produce multiple outputs and operate with considerable inefficiency. We estimate Lerner indices for U.S. banks for 2001-18 using...
