Crime and violence: Desensitization in victims to watchingcriminal events
(Universidad Torcuato Di TellaJournal of Economic Behavior & Organization (e-ISSN: 1879-1751), 2019)We study desensitization to crime in a lab experiment by showing footage of criminal acts to a group of subjects, some of whom have been previously victimized. We measure biological markers of stress and behavioral indices ... -
Analysis of a generalized Linear Ordering Problem via integer programming
(Discrete Applied Mathematics (e-ISSN: 1872-6771), 2019-12-01)We study a generalized version of the linear ordering problem: Given a collection of partial orders represented by directed trees with unique root and height one, where each tree is associated with a nonnegative reward, ... -
The Value of Observing the Buyer Arrival Time in Dynamic Pricing
(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
(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 ... -
Human Capital Investment and Development: The Role of Onthe- Job Training
(Universidad Torcuato Di TellaPeking UniversityUniversity of Connecticut, 2022)Workers in richer countries experience faster rates of wage growth over their lifetimes than workers in poorer countries. We offer an explanation for this pattern by showing that workers in richer economies receive more ... -
Facet-generating procedures for the maximum-impact coloring polytope
(2023)Given two graphs G = (V, EG) and H = (V, EH) over the same set of vertices and given a set of colors C, the impact on H of a coloring c : V → C of G, denoted I(c), is the number of edges ij ∈ EH such that c(i) = c(j). ... -
Government Turnover and External Financial Assistance
(Universidad Torcuato Di Tella, 2023)We study the political incentives shaping governments’ decisions to seek assistance from a lender of last resort. We propose that re-elected incumbents are more reluctant than newly elected governments to request assistance, ... -
Solving the Traveling Salesman Problem with release dates via branch and cut
(EURO Journal on Transportation and Logistics (ISSN 2192-4384)Elsevier, 2023)In this paper we study the Traveling Salesman Problem with release dates (TSP-rd) and completion time minimization. The TSP-rd considers a single vehicle and a set of customers that must be served exactly once with goods ... -
A polyhedral study of a relaxation of the routing and spectrum allocation problem
(Procedia Computer ScienceElsevier, 2023)The routing and spectrum allocation (RSA) problem arises in the context of flexible grid optical networks, and consists in routing a set of demands through a network while simultaneously assigning a bandwidth to each ... -
Multiobjective formulation for last-mile optimization in wireless networks
(IEEE2023 XLIX Latin American Computer Conference (CLEI), 2023)Internet of Things (IoT) is a technology that serves as the basis for smart environments. The ever-expanding set of applications that provide intelligence in different scenarios is continually growing and expanding. From ... -
A Value-Based Well-Being Framework
(Journal of MacromarketingSAGE, 2023)This article presents and illustrates a novel value-based well-being framework, derived from service-dominant logic notions of the link between value and well-being. Based in a wide range of disciplines, this framework ... -
A branch-and-cut algorithm for the routing and spectrum allocation problem
(Universidad Torcuato Di Tella, 2023)One of the most promising solutions to deal with huge data traffic demands in large communication networks is given by flexible optical networking, in particular the flexible grid (flexgrid) technology specified in the ... -
An integer programming approach for the hyper-rectangular clustering problem with axis-parallel clusters and outliers
(Universidad Torcuato Di Tella, 2023)We present a mixed integer programming formulation for the problem of clustering a set of points in Rd with axis-parallel clusters, while allowing to discard a pre-specified number of points, thus declared to be outliers. ... -
Valid inequalities and complete characterizations of the 2-domination and P3-hull number polytope
(Universidad Torcuato Di Tella, 2023)Given a graph G = (V;E), a subset S V is 2-dominating if every vertex in S has at least two neighbors in S. The minimum cardinality of such a set is called the 2-domination number of G. Consider a process in discrete ... -
Mudding the playing field. Fiscal contributions to municipalities as a political construction
(Governance: An international Journal of Policy, Administration, and InstitutionsWiley, 2023)In federal presidential democracies, discretionary transfers are often mentioned as a tool used by the national executive to build and strengthen subnational support, typically governors. Funds to local mayors, however, ... -
Demand Estimation under Uncertain Consideration Sets
(Operations Research (ISSN: 0030-364X), 2023-09)To estimate customer demand, choice models rely both on what the individuals do and do not purchase. A customer may not purchase a product because it was not offered but also because it was not considered. To account for ... -
The Potential Footprint of Plant- Based Meat Adoption on Leading Crop Producers
(Universidad Torcuato Di Tella, 2023-12-30)Plant-based meat (PBM) has the potential to improve the global food supply chain on numerous environmental and societal dimensions. Some of these gains, derived from lower animal meat production, could disrupt the supply ... -
A branch-cut-and-price algorithm for the time-dependent electric vehicle routing problem with time windows
(European Journal of Operational ResearchElsevier, 2024)The adoption of electric vehicles (EVs) within last-mile deliveries is considered one of the key transformations towards more sustainable logistics. The inclusion of EVs introduces new operational constraints to the models ... -
Implicit carbon prices: Making do with the taxes we have
(Journal of Environmental Economics and Management (Online ISSN: 1096-0449), 2024)Climate and fiscal policy interact closely. The former imposes explicit prices for carbon emissions, while the latter affects emissions implicitly. We study the correspondence between explicit and implicit carbon pricing ... -
Extreme Dry Spells and Larger Storms in the U.S. Midwest Raise Crop Prices
(RedNIE Red Nacional de Investigadores en Economía, 2024)The U.S. Midwest produces about a third of global corn and soybeans, two of the most important crops for humanity. Earlier literature has found that corn and soybean output is sensitive to weather in a nonlinear manner: ...
