We develop a model of international trade with heterogeneous firms and endogenous quality choices. Producing higher quality involves returns to scale, it is intensive in skilled labor and high-quality inputs. Firms' quality choices are interrelated because firms sell their goods to consumers and...

We use plant output and input prices to decompose the profit margin into four parts: productivity, demand shocks, mark-ups and input costs. We find that each of these market fundamentals are important in explaining plant exit. We then use variation across sectors in tariff changes after the...

In the U.S., some sectoral evidence suggests that growth is driven mainly by productivity enhancing reallocation. In countries with greater barriers to entry and imperfect competition, the reallocation process may be inefficient. Therefore, for developing countries, an open question is whether...

We analyze employment and capital adjustments using plant data from the Colombian Annual Manufacturing Survey. We estimate adjustment functions for capital and labor as a non-linear function of the gaps between desired and actual factor levels, allowing for interdependence in adjustments of the...

Using transactions-level customs data from Colombia, we study firm-specific export patterns over the period 1996-2005. Our data allow us to track firms' entry and exit into and out of individual destination markets, as well as their revenues from selling there. We find that, in a typical year,...

We present a model of political budget cycles in which incumbents influence voters by targeting government spending to specific groups of voters at the expense of other voters or other expenditures. Each voter faces a signal extraction problem: being targeted with expenditure before the election...

We present a model of the Political Budget Cycle in which voters and politicians have preferences for different types of government spending. Incumbents try to influence voters by changing the composition of government spending, rather than overall spending or revenues. Rational voters may...
