This paper shows that in a buffer stock saving model, wealth-to-income and other interesting variables have unique stable invariant distributions. Previously this ergodic property has only been conjectured and demonstrated numerically by means of simulations. The proof proceeds by extending earlier results about the existence and uniqueness of an ergodic distribution to Markov processes on non-...
Using a laboratory experiment, we identify whether decision-makers consider it mistake to violate canonical choice axioms. To do this, incentivize subjects report axioms they want their decisions satisfy. Then, make lottery choices which might conflict with axiom preferences. In instances of conflict, give the opportunity re-evaluate decisions. We find that many individuals follow and revise be...
We explore here the potential of a newly described technology, which is named PROFILER and is based on next generation sequencing of gene-specific lambda phage-displayed libraries, to rapidly and accurately map monoclonal antibody (mAb) epitopes. For this purpose, we used a novel mAb (designated 31E10/E7) directed against Neisserial Heparin-Binding Antigen (NHBA), a component of the anti-group ...
We have used continuum electrostatic methods to investigate the role of electrostatic interactions in the structure, function, and pH-dependent stability of the fungal Rhizomucor miehei lipase (RmL) family. We identify a functionally important electrostatic network which includes residues S144, D203, H257, Y260, H143, Y28, R80, and D91 (residue numbering is from RmL). This network consists of r...
We provide quasi-experimental estimates of the impact social media on mental health by leveraging a unique natural experiment: staggered introduction Facebook across US colleges. Our analysis couples data student around years Facebook’s expansion with generalized difference-in-differences empirical strategy. find that rollout at college had negative health. It also increased likelihood which st...
Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people's emotions over time predicts changes risk attitudes. Using a large-panel dataset, identify happiness, anger, and fear as significant correlates of within-person Robustness checks indicate limited role alternat...
The Earned Income Tax Credit distributes more than $60 billion to over 20 million low-income families annually. Nevertheless, an estimated one-fifth of eligible households do not claim it. We ran six preregistered, large-scale field experiments with 1 observations test whether “nudges” could increase EITC take-up. Despite varying the content, design, messenger, and mode our messages, we find no...
