Parag Pathak: Winner of the 2018 Clark Medal
The American Economic Association awarded Parag Pathak the 2018 John Bates Clark Medal for his research on the impacts of educational policies. Both the theory and the empirical research take the constraints facing administrators seriously. As a result, Parag’s research led directly to educational reforms in many large US cities and abroad. The leading example is Parag (and co-authors’) research on school assignment mechanisms that led many schoo…
Lying and Deception in Games
This article proposes definitions of lying, deception, and damage in strategic settings. Lying depends on the existence of accepted meanings for messages but does not require a model of how the audience responds to messages. Deception does require a model of how the audience interprets messages but does not directly refer to consequences. Damage requires consideration of the consequences of messages. Lies need not be deceptive. Deception does not…
Lying Aversion and the Size of the Lie
This paper studies lying. An agent randomly picks a number from a known distribution. She can then report any number and receive a monetary payoff based only on her report. The paper presents a model of lying costs that generates hypotheses regarding behavior. In an experiment, we find that the highest fraction of lies is from reporting the maximal outcome, but some participants do not make the maximal lie. More participants lie partially when th…
Travel- and Community-Based Transmission of Multidrug-Resistant Shigella sonnei Lineage among International Orthodox Jewish Communities
Shigellae are sensitive indicator species for studying trends in the international transmission of antimicrobial-resistant Enterobacteriaceae. Orthodox Jewish communities (OJCs) are a known risk group for shigellosis; Shigella sonnei is cyclically epidemic in OJCs in Israel, and sporadic outbreaks occur in OJCs elsewhere. We generated whole-genome sequences for 437 isolates of S. sonnei from OJCs and non-OJCs collected over 22 years in Europe (th…
P2-123 Evaluation of risk factor and protection for chronic non communicable diseases monitoring system by phone survey: Vigitel, Brazil 2006 to 2008
Vigitel is a system that monitors risk factors by means of continuous telephone interviews on samples of adults living in households with landline telephones in the Brazilian capital. To evaluate the system from 2006 to 2008, we used the Updated Guidelines for Evaluating Public Health Surveillance Systems from CDC, semi-structured questionnaires for interviews with key-informants and comparisons to other surveys, such as the BRFSS
Intoxicação por exposição à rapadura em três municípios do Rio Grande do Norte, Brasil: Uma Investigação De Epidemiologia De Campo
O estudo objetivou descrever dois surtos de intoxicação por exposição à rapadura, ocorridos em três municípios do estado do Rio Grande do Norte, entre janeiro e fevereiro de 2008. Foi conduzida uma investigação epidemiológica com a realização de estudo de caso. Outras investigações, laboratorial e ambiental, complementaram o quadro de informações sobre os surtos. Foram oito casos prováveis por exposição à rapadura, dos quais cinco por consumo do …
First reported outbreak of green tobacco sickness in Brazil
Dermal absorption of nicotine by people harvesting tobacco may cause an acute intoxication called green tobacco sickness. Although Brazil is the second largest producer of tobacco in the world, green tobacco sickness had not been reported in the country to date. We conducted a 1:1 matched case-control study among persons involved in tobacco farming to determine the occurrence of green tobacco sickness in the northeast region of Brazil and to iden…
Interdependent Preferences and Reciprocity
Experiments, ethnography, and introspection provide evidence economic agents do not act to maximize their narrowly defined self interest. Expanding the domain of preferences to include the utility of others provides a coherent way to extend rational choice theory. There are two approaches for including extended or social preferences in strategic models. One posits that agents have extended preferences, but maintains the conventional assumption th…
Can We Trust Social Capital
How to Count to One Thousand
An agent must verify that n objects are present. While counting, the agent might lose track and need to start over. The scheme that minimizes the expected counting time involves several layers in which objects are grouped into stacks, which are grouped into stacks of stacks, and so on. The size of each division depends only on the probability of making a mistake; the number of levels in the process increases with the logarithm of the size of the …
Equilibrium Selection in Signaling Games
This paper studies the sequential equilibria of signaling games. It introduces a new solution concept, divine equilibrium, that refines the set of sequential equilibria by requiring that off-the-equilibrium-path beliefs satisfy an additional restriction. This restriction rules out implausible sequential equilibria in many examples. We show that divine equilibria exist by demonstrating that a sequential equilibrium that fails to be divine cannot b…
A Theory of Credibility
This paper presents models in which one agent must decide whether to trust another, whose motives are uncertain. Reliability can only be communicated through actions. In this context, it pays for people to build a reputation based on reliable behaviour; someone becomes credible by consistently providing accurate and valuable information or by performing useful services. The theory provides a justification for long-term arrangements without bindin…
Strategic Information Transmission
This paper develops a model of strategic communication, in which a better-informed Sender (S) sends a possibly noisy signal to a Receiver (R), who then takes an action that determines the welfare of both. We characterize the set of Bayesian Nash equilibria under standard assumptions, and show that equilibrium signaling always takes a strikingly simple form, in which S partitions the support of the (scalar) variable that represents his private inf…
