Dynamic Reserves in Matching Markets

Abstract: Indian Engineering school admissions, which draws more than 300,000 applications per year, suffers from an important market failure: Through their affirmative action program certain number of seats are reserved for different lower castes and tribes. However, when some of these seats are unfilled they are not offered to other groups, and the system is vastly wasteful. Moreover, since students care not only about the school they are assigned to but also whether they are assigned through reserves or not, they may strategically manipulate the system by both not revealing their privilege type and changing their preferences over schools. In this paper, we propose a new matching model with contracts with the ability to release vacant seats to the use of other students by respecting certain affirmative action objectives. We design a new choice function for schools that respects affirmative action objectives, avoids waste, and increases efficiency. We propose a mechanism that is stable, strategy proof, and respects test score improvements with respect to these choice functions. Moreover, we show that some distributional objectives that can be achieved by capacity transfers cannot be achieved by slot-specific priorities (i.e., lexicographic choice functions).

¡Vamos!: Observations of Pedestrian Interactions with Driverless Cars in Mexico

Abstract: How will pedestrians from different regions interact with an approaching autonomous vehicle? Understanding differences in pedestrian culture and responses can help inform autonomous cars how to behave appropriately in different regional contexts We conducted a field study comparing the behavioral response of pedestrians between metropolitan Mexico City (N=113) and Colima, a smaller coastal city (N=81) We hid a driver in a car seat costume as a Wizard-of-Oz prototype to evoke pedestrian interaction behavior at a crosswalk or street Pedestrian interactions were coded for crossing decision, crossing pathway, pacing, and observational behavior Most distinctly, pedestrians in Mexico City kept their pace and more often crossed in front of the vehicle, while those in Colima stopped in front of the car more often

Platinum-based chemotherapy in triple-negative advanced breast cancer

Abstract: The purpose of this study was to evaluate the efficacy of platinum-based chemotherapy (PBC) versus conventional non-PBC regimens in a metastatic triple-negative breast cancer (TNBC) setting. We reviewed the electronic patient records of patients with confirmed metastatic TNBC at four major cancer centres in Canada. All patients were allocated into two groups based on type of chemotherapy received (PBC vs. non-PBC) and line of treatment (first-, second-, or third-line). The primary objective of this study was to evaluate the efficacy of PBC in metastatic TNBC in terms of median duration of overall survival (OS) from diagnosis of distant metastatic disease and compare it with the efficacy of conventional non-platinum-based chemotherapy in metastatic TNBC after controlling for known prognostic factors. A total of 153 metastatic TNBC patients were identified, 58 treated with PBC and 95 with non-PBC. The median time in first-line PBC versus non-PBC was not different between the two groups (2 vs. 2 months, p = 0.9), the median time on treatment in second and third-line therapy was longer for the PBC group compared to the conventional treated group (4 vs. 1 months, p = 0.004; 4 vs. 0.5 months, p = 0.004, respectively). Patients who received PBC had a longer OS compared to those managed conventionally (14.5 vs. 10 months, p = 0.041). This study evaluates the survival outcomes in a homogenous group of TNBC metastatic patients treated with or without PBC. Our results confirmed our hypothesis of a better OS among PBC-treated TNBC patients compared to conventionally managed TNBC patients. Currently ongoing Phase III trials assessing the benefit of PBC versus other chemotherapeutic regimens in advanced TNBC will help define the role of these agents for the management of this breast cancer subtype.
