This paper develops the nonparametric identification of models with production complementarities, worker-firm specific disutility of labour and search frictions. Mobility in the model is subject to preference shocks, and we assume that firms can write wage contracts. We develop a constructive...

This paper shows the importance of technological synergies among heterogeneous firms for aggregate fluctuations. First, we document six novel empirical facts using microdata that suggest the existence of important technological synergies between trading firms, the presence of positive...

The received characterizations of feasible interim allocations are mostly in the spirit of Border (1991): Fix a family of sets, each containing some player-types, and test the interim allocation under consideration against all these sets. In the published literature, such Border-like...

The 2022 Household Income and Expenditure Survey enhances fieldwork, data management, and information quality but poses comparability challenges with previous rounds. This study proposes a two-step process based on statistical matching to fill the information gap in previous survey rounds. This...

This paper investigates the role of worker-firm matching algorithms in accounting for early job separation rates. For this purpose, we examine Korea's temporary foreign worker program in which the government classifies firms by priority levels and matches them with foreign workers based on their...
