This paper assesses the potential impact of FinTech on the finance industry, focusing on financial stability and access to services. I document first that financial services remain surprisingly expensive, which explains the emergence of new entrants. I then argue that the current regulatory...

Schumpeter's concept of creative destruction as the engine of capitalist development is well-known. However, that the destructive part of creative destruction is a social cost and therefore biases our estimate of the impact of the innovation on NNP and on welfare is hardly acknowledged, with the...

In this paper I discuss the ways in which populist experiments have evolved historically. Populists are charismatic leaders that use a fiery rhetoric to pitch the interests of "the people" against those of banks, large firms, multinational companies, the IMF, and immigrants. Populists implement...

I use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on GDP per capita. I employ avariety of methods to construct estimates of the return to health, which I combine with cross-country and historical...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...

I address the controversy over whether the financial services industry is "too big." We should be asking whether the finance industry is functioning properly instead. The facts suggest that demand for financial services increased, perhaps temporarily, rather than suggesting a changing distortion...

I provide a quantitative interpretation of financial intermediation in the U.S. over the past 130 years. Measuring separately the cost of intermediation and the production of financial services, I find that: (i) the quantity of intermediation varies a lot over time; (ii) intermediation is...

This paper makes three points regarding the proper measurement of the output of financial intermediaries. Two of them concern the measurement of nominal financial output, especially banking output. First, we show that, to impute the nominal value of implicitly priced financial output, it is...

How does technological progress in financial intermediation affect the economy? To address this question a costly-state verification framework is embedded into a standard growth model. In particular, financial intermediaries can invest resources to monitor the returns earned by firms. The...
