A well-known fact in the time series of aggregate output is the persistence of shocks. This paper argues that the empirical relation between the expected growth rate of a firm and its size provides a microfoundation of aggregate persistence. In fact, the empirical evidence claims that small...

We use a comprehensive Swedish credit register to document that firms throughout the size distribution have access to fairly large and reasonably priced credit lines, but borrow relatively little from them. We rationalize this using a theoretical framework in which the expected cost of financial...

After 162 years of political unification, Italy still displays large regional economic differences. In 2019, the per capita GDP of Lombardia was 39,700 euros, but Calabria's per capita GDP was only 17,300 euros. We build a two-region, two-sector model of the Italian economy to measure the wedges...

We study a model with repeated moral hazard where financial contracts are not fully indexed to inflation because nominal prices are observed with delay as in Jovanovic & Ueda (1997). More constrained firms sign contracts that are less indexed to the nominal price and, as a result, their...

We show that higher interconnectivity among financial intermediaries induces banks to choose more leverage. Although this leads to higher investment growth, the banking sector becomes more vulnerable to aggregate shocks (crises). We also show that learning about the likelihood of a crisis could...
