Much of her work constructs dynamic, stochastic, general equilibrium (DSGE) models. These models incorporate heterogeneous agents on the producer side; entry and exit dynamics; fixed exporting costs; production linkages; and iceberg trade costs to explain empirical regularities identified in the literature on international real business cycles (IRBC) through calibration and simulation. Her main goal is to explore the aggregate implications of micro-level firm dynamics in open economies, explaining along the way how the models matter for international transmission and trade policy.
