• Using iterated local search for solving the flow-shop problem: parametrization, randomization and parallelization issues

  Juan, Angel A.; Ramalhinho-Lourenço, Helena; Mateo, Manuel; Luo, Rachel; Castella, Quim (Wiley, 2013)

  Iterated local search (ILS) is a powerful framework for developing efficient algorithms for the permutation flow‐shop problem (PFSP). These algorithms are relatively simple to implement and use very few parameters, which ...
• Maximum likelihood estimation of the latent class model through model boundary decomposition

  Allman, Elizabeth Spencer, 1965-; Baños Cervantes, Hector; Evans, Robin; Hoşten, Serkan; Kubjas, Kaie; Lemke, Daniel; Rhodes, John A. (John Anthony), 1960-; Zwiernik, Piotr (New York Business Global, 2019)

  The Expectation-Maximization (EM) algorithm is routinely used for maximum likelihood estimation in latent class analysis. However, the EM algorithm comes with no global guarantees of reaching the global optimum. We study ...
• Reasoning about others' reasoning

  Alaoui, Larbi; Janezic, Katharina A.; Penta, Antonio (Elsevier, 2020)

  Recent experiments suggest that level-k behavior is often driven by subjects' beliefs, rather than their binding cognitive bounds. But the extent to which this is true in general is not completely understood, mainly because ...
• Common value experimentation

  Eeckhout, Jan; Weng, Xi (Elsevier, 2015)

  In many economic environments, agents often continue to learn about the same underlying state variable, even if they switch action. For example, a worker's ability revealed in one job or when unemployed is informative about ...
• Sorting through search and matching models in economics

  Chade, Hector; Eeckhout, Jan; Smith, Lones (American Economic Association, 2017)

  Toward understanding assortative matching, this is a self-contained introduction to research on search and matching. We first explore the nontransferable and perfectly transferable utility matching paradigms, and then a ...
• Sorting in the labor market

  Eeckhout, Jan (Annual Reviews, 2018)

  This review surveys the literature on sorting in the labor market. There are inherent differences in worker ability and across-firm productivity. Two fundamental questions are whether the exact composition of skills of ...
• Unemployment cycles

  Eeckhout, Jan; Lindenlaub, Ilse (American Economic Association, 2019)

  The labor market by itself can create cyclical outcomes, even in the absence of exogenous shocks. We propose a theory in which the search behavior of the employed has profound aggregate implications for the unemployed. ...
• Marketing agencies and collusive bidding in online ad auctions

  Decarolis, Francesco; Goldmanis, Maris; Penta, Antonio (INFORMS, 2020)

  The transition of the advertising market from traditional media to the internet has induced a proliferation of marketing agencies specialized in bidding in the auctions that are used to sell ad space on the web. We analyze ...
• Investor experiences and international capital flows

  Malmendier, Ulrike; Pouzo, Demian; Vanasco, Victoria (Elsevier, 2020)

  We propose a novel explanation for classic international macro puzzles regarding capital flows and portfolio investment, which builds on modern macro-finance models of experience-based belief formation. Individual experiences ...
• Optimal transport networks in spatial equilibrium

  Fajgelbaum, Pablo; Schaal, Edouard (Wiley, 2020)

  We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through ...
• Bounded rationality in Keynesian beauty contests: a lesson for central bankers?

  Mauersberger, Felix; Nagel, Rosemarie; Bühren, Christoph (European Mathematical Society, 2020)

  The great recession (2008) triggered an apparent discrepancy between empirical findings and macroeconomic models based on rational expectations alone. This gap led to a series of recent developments of a behavioral ...

  López i Casasnovas, Guillem (Elsevier, 1993)

  La dinàmica que I'enginyeria gerencial és capaç de crear en el sector sanitari és, a l'actualitat, enorme. Això fa convenient, de tant en tant, fer una espècie de ‘parada i fonda’ per bé d'analitzar la consistència a la ...
