Using a new firm-level dataset on private and listed firms from 20 countries, we document five stylized facts on market power in global markets. First, competition has declined around the world, measured as a moderate increase in average firm markups during 2000- 2015. Second, the markup...

This paper explicitly takes into account the dynamic oligopolistic rivalry among source producers to evaluate the degree of exchange rate pass-through. Using recent time-series techniques for the case of imported automobiles in Switzerland, the results show that prices are strategic complements...

Tax laws and administrations often treat different size firms differently. There is, however, little research on the consequences. As modeled here, oligopolists with different efficiencies determine the size distribution of firms. A government that maximizes a weighted sum of consumer surplus,...

This paper develops a model where large financial intermediaries subject to systemic runs internalize the effect of their leverage on aggregate risk, returns and asset prices. Near the steady-state, they restrict leverage to avoid the risk of a run which gives rise to an accelerator effect. For...

When a country''s banking system becomes more linked to the global banking network, does that system get more or less prone to a banking crisis? Using model simulations and econometric estimates based on a world-wide dataset, we find an M-shaped relationship between financial stability of a...

This paper studies banks' decision to form financial interconnections using a model of financial contagion that explicitly takes into account the crisis state of the world. This allows us to model the network formation decision as optimising behaviour of competitive banks, where they balance the...

This paper computes data-driven correlation networks based on the stock returns of international banks and conducts a comprehensive analysis of their topological properties. We first apply spatial-dependence methods to filter the effects of strong common factors and a thresholding procedure to...

We show that domestic production networks shape worker flows between firms. Data on the universe of firm-to-firm transactions for the Dominican Republic, matched with employer-employee records, reveals that about 20 percent of workers who change firms move to a buyer or supplier of their...
