Artigo Científico Exploring the causal effects of the built environment on travel behavior: a unique randomized experiment in Shanghai(2022) Chen, Faan; ADRIANO BORGES FERREIRA DA COSTAExperimental designs have been recognized as the gold standard for establishing causal mechanisms. However, the application of such designs is complicated by factors such as excessive costs, time consumption, ethical concerns, and political impossibility. Nevertheless, the Chinese government’s replacement housing efforts provide a unique randomized experiment for exploring the causal effects of the built environment on travel behavior. Accordingly, based on a large-scale survey on travel patterns under an experimental design in Shanghai, this study employs a two-step modeling approach, involving logit and Tobit models, to identify the built environment’s effects on auto ownership and vehicle kilometers traveled (VKT). We found that transit service improvements play a stronger role in reducing auto-drive than compact and diverse land-use characteristics. Increasing residential and employment density, as well as land-use mix, discourages car ownership, which in turn reduces VKT, but with lower elasticities than transportation system variables. The findings provide additional evidence and referential estimate for how land-use and transport strategies and policies designed to create a compact, mixed-use, and highly accessible built environment can be used in reducing auto driving. This study expands the VKT reduction elasticities’ database regarding the built environment across global spatial contexts, serving as a model for similar studies elsewhere in the world.Artigo Científico Apply the Laws, if They are Good: Moral Evaluations Linearly Predict Whether Judges Should Enforce the Law(2024) Engelmann, Neele; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Sousa, Felipe Oliveira de; Prochownik, Karolina; Hannikainen, Ivar R.; Struchiner, Noel; Magen, StefanWhat should judges do when faced with immoral laws? Should they apply them without exception, since “the law is the law?” Or can exceptions be made for grossly immoral laws, such as historically, Nazi law? Surveying laypeople (N = 167) and people with some legal training (N = 141) on these matters, we find a surprisingly strong, monotonic relationship between people’s subjective moral evaluation of laws and their judgments that these laws should be applied in concrete cases. This tendency is most pronounced among individuals who endorse natural law (i.e., the legal-philosophical view that immoral laws are not valid laws at all), and is attenuated when disagreement about the moral status of a law is considered reasonable. The relationship is equally strong for laypeople and for those with legal training. We situate our findings within the broader context of morality’s influence on legal reasoning that experimental jurisprudence has uncovered in recent years, and consider normative implications.Artigo Científico Alpha-maxmin as an aggregation of two selve(2024) Chateauneuf, Alain; JOSÉ HELENO FARO; Tallon, Jean-Marc; Vergopoulos, VassiliThis paper offers a novel perspective on the -maxmin model, taking its components as originating from distinct selves within the decision maker. Drawing from the notion of multiple selves prevalent in inter-temporal decision-making contexts, we present an aggregation approach where each self possesses its own preference relation. Contrary to existing interpretations, these selves are not merely a means to interpret the decision maker’s overall utility function but are considered as primitives. Through consistency requirements, we derive an -maxmin representation as an outcome of a convex combination of the preferences of two distinct selves. We first explore a setting involving objective information and then move on to a fully subjective derivation.
