    • The Value of Observing the Buyer Arrival Time in Dynamic Pricing 

      Vulcano, Gustavo; Correa, José; Pizarro, Dana (2020)
      We consider a dynamic pricing problem where a firm sells one item to a single buyer in order to maximize expected revenues. The firm commits to a price function over an infinite horizon. The buyer arrives at some random ...

    • The maximum 2D subarray polytope: facet-inducing inequalities and polyhedral computations 

      Marenco, Javier; Koch, Ivo (2022)
      Given a matrix with real-valued entries, the maximum 2D subarray problem consists in finding a rectangular submatrix with consecutive rows and columns maximizing the sum of its entries. In this work we start a polyhedral ...

    • Equilibrium and Real Options in the Ethanol Industry: Modelling and Empirical Evidence 

      Merener, Nicolás; Davison, Matt (Journal of Commodity MarketsElsevier B.V., 2022)
      In the last twenty years a large number of competitive ethanol rms have estab- lished operations in the US. Ethanol, produced from corn, is blended with pure gasoline to produce fuel. Producers hold an option to turn o ...

    • Exploiting user-frequency information for mining regionalisms in Argentinian Spanish from Twitter 

      Gravano, Agustín; Pérez, Juan Manuel; Aleman, Damian E.; Kalinowski, Santiago N. (Procesamiento del Lenguaje Natural, Revista, 2022)
      The task of detecting regionalisms (expressions or words used in certain regions) has traditionally relied on the use of questionnaires and surveys, heavily depending on the expertise and intuition of the surveyor. The ...

    • The globalizability of temporal discounting 

      Navajas, Joaquin; Freiras, Lucía; et al. (Nature Human Behaviour, 2022)
      Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of ...

    • Working Memory for Spatial Sequences: Developmental and Evolutionary Factors in Encoding Ordinal and Relational Structures 

      Sigman, Mariano; He Shang; Yanfen Zhen; Shijing Yu; Tenghai Long; Bingqian Zhang; Xinjian Jiang; Junru Li; Wen Fang; Dehane, Stanislas; Liping Wang (Journal of Neuroscience, 2022)

    • Imagetic and affective measures of memory reverberation diverge at sleep onset in association with theta rhythm 

      Sigman, Mariano; Bezerra Mota, Natália; Soares, Ernesto; Altszyler, Edgar; Sánchez-Gendriz, Ignacio; Muto, Vincenzo; Heib, Dominik; Slezak, Diego F.; Copelli, Mauro; Schabus, Manuel; Ribeiro, Sidarta (Elsevier Inc, 2022)
      The ‘day residue’ - the presence of waking memories into dreams - is a century-old concept that remains controver- sial in neuroscience. Even at the psychological level, it remains unclear how waking imagery cedes into ...

    • Chronotype at the beginning of secondary school and school timing are both associated with chronotype development during adolescence 

      Goldín, Andrea Paula; Sigman, Mariano; Rodríguez Ferrante, Guadalupe; Leone, María Juliana (Scientific Reports, 2022)
