Journal of Economic Literature, forthcoming. With R. Wright,B. Julien, and V. Guerrieri. This survey presents a comprehensive overview of the directed/competitive search literature. Find Out More

Economic Journal, forthcoming. With EricsonSpinnewijn &, Starc Demand for insurance can be driven by high risk aversion or high risk, and we show how to separate the two using observed market shares. Find Out More

Review of Economic Studies, 2019 86(4): 1411-1447.  With Michèle Belot and Paul Muller. We develop and evaluate experimentally a novel tool that redesigns the job search process by providing tailored online advice about related occupations. Find Out More

Econometrica, 2019 87(4): 1081-1113. With J. GreenwoodC. Santos and M. Tertilt A calibrated equilibrium search model of an HIV/AIDS epidemic is developed to analyze the direct impact and the behavioral adjustment to policies. Find Out More

Econometrica. 2018 86(1): 85-132. With Jan Eeckhout. When heterogeneous firms can choose both how many and which workers to hire, we illustrate consequences for firm-size and wage inequality. Note a correction for the condition with capital: corrigendum. Find Out More

American Economic Review P&P, 2017, 107(5): 158–162 With J. GreenwoodC. Santos & M. Tertilt. In a quantitative equilibrium model of sexual behavior and HIV/AIDS transmission we study policies that encourage long-term partnerships. Find Out More

Journal of Political Economy, 2017, 124(1), 224-264. With G. Grossman & E. Helpman. (simulationsmatlab). We introduce two-sided heterogeneity into a Hecksher-Ohlin-style trade model to study factor reallocation and wage inequality within and across sectors. Find Out More

Econometrica2015, Vol 83 (5), 1849-1875. With K. Kim. [online appendix] We introduce cheap-talk into a market game and study if the equilibrium can replicate the constraint efficient allocation under (reserve) price posting. Find Out More

American Economic Review, 2015, Vol 105 (10), 3030-3060. With Leo Kaas. We propose a tractable competitive search model with heterogeneous multi-worker firms, and investigate firm growth and business cycles. Find Out More

Review of Economic Studies, 2015, Vol 82 (2), 659-692. With Fane Groes and Iourii Manovskii. Occupational mobility is highest for high and low earners, and the former move “up” and the latter “down” as in models of vertical re-sorting. Find Out More

B.E. Journals of Theoretical Economics, 2013, Vol 13 (1). With S. Ludwig and A. Sandroni. We document a revealed preference for randomization for “social goods”, while such non-standard behavior is not present for private consumption goods. Find Out More

International Economic Review, 2012, Vol 53 (1), 1-21. With M. Galenianos. We study a finite directed-search wage posting game among heterogeneous firms (allowing for risk aversion, moral hazard,…), including limit theorems. Find Out More

Review of Economic Studies, 2011, Vol. 78 (3), 872-906. With Jan Eeckhout. Wage and employment data can identify the strength of sorting in search models, though two-sided fixed effects are always mis-specified. Find Out More

International Economic Review, 2011, 52(1), pp 85-104. With M. Galenianos and G. Virag. [technical appendix] In directed search with a finite population, minimum wages improve employment but reduce output and efficiency, and reverse for unemployment benefits. Find Out More

Econometrica, 2010, Vol. 78(2), 539–574. With Jan Eeckhout. In search models with price competition the sorting of heterogeneous buyers and sellers depends on complementarities both in output and in search. Find Out More

Journal of Economic Theory, 2010/145, 1354-1385. With Jan Eeckhout. Search affects competing mechanisms: if meetings with low types reduce those of high types, price posting and market separation replace auctions. Find Out More

Journal of Political Economy, 2009, Vol. 117(5), pp. 861- 913. In a directed search where workers apply for multiple jobs and are then allocated via a stable matching, efficiency arises at all stages. Find Out More

Journal of Economic Theory, 2009, 114(2), pp. 445-471. With Manolis Galenianos. We study wage dispersion and (in)efficiency in directed search when workers can strategically apply for multiple jobs but firms can only make one offer. Find Out More

Journal of Monetary Economics, 2008, Vol. 55, pp. 1054-1066. With M. Galenianos. We characterize price dispersion and welfare in a monetary model with private information: inflation is regressive even though the rich hold more money. Find Out More

Quarterly Journal of Economics, 2008/123(2), pp. 621-661. With A. Postlewaite. [technical appendix] In a model of social learning, the better informed (wealthier) consumers get preferential service because their consumption signals high quality to others. Find Out More
