Assortative Matching between workers and firms provides evidence of the complementarities or substitutes in production. The presence of complementarities is important for policies that aim to achieve the optimal allocation of resources, for example unemployment insurance. We argue that using...

We argue that using wage data alone, it is virtually impossible to identify whether Assortative Matching between worker and firm types is positive or negative. In standard competitive matching models the wages are determined by the marginal contribution of a worker, and the marginal contribution...

We analyze the efficiency properties of price posting in a market where sellers compete for the buyers' business. They key feature of the approach is to investigate price posting as an equilibrium outcome even if sellers can compete with other mechanisms. When buyers are homogeneous, we show...

When firms choose the allocation of workers, they can adjust not only the type of worker, the extensive margin, but also the intensive margin, how many of those worker to employ. We propose a tractable matching model with such factor intensity. Positive sorting arises under...

Econometrica publishes original articles in all branches of economics - theoretical and empirical, abstract and applied, providing wide-ranging coverage across the subject area. It promotes studies that aim at the unification of the theoretical-quantitative and the empirical-quantitative...

In a market where sellers compete by posting trading mechanisms, we allow for a general search technology and show that its features crucially affect the equilibrium mechanism. Price posting prevails when meetings are rival, i.e., when a meeting by one buyer reduces another buyer's meeting...
