        "description":"Eliciting the marginal propensity to consume (MPC) in surveys has become an important source of data for both researchers and policymakers. This talk will report on survey experiments designed to study two puzzles that have emerged in this literature. The between-study puzzle is that average MPCs vary substantially across surveys. We show in a randomized survey experiment that elicited MPCs are quite sensitive to question wording. The within-study puzzle is that that elicited MPCs are poorly correlated with measures of liquidity (and other observables). We conducted text analysis of open-format follow-up questions to a standard MPC elicitation question. The results suggest that the within-study puzzle is primarily driven by nonstandard behaviors (such as mental accounting) rather than respondent misunderstanding of questions or other measurement problems.",

        "description":"Evolutionary trade-offs between fecundity and survival are ubiquitous in evolution. In high-latitude seasonal environments, most birds breed during resource-rich summers, and migrate to lower-latitude environments during the winter to survive. However, the trade-off between fecundity and survival appears to scale with migration distance: By migrating farther, birds may gain higher survival benefits, but in doing so, they sacrifice time that they might have spent raising offspring. Longer migrations are thus associated with \"slower\" life histories (higher survival, fewer offspring), but this apparently straightforward trade-off belies an intriguing underlying paradox: Slower life histories are typically associated with lower genetic diversity, but in migratory birds, there is evidence that longer migrations are positively correlated with genetic diversity, possibly because they promote demographic stability. Nevertheless, populations of long-distance migrants readily switch strategies, implying that populations will move quickly toward new optima if migration\u2019s survival benefits no longer outweigh its reproductive costs, with unknown population genetic consequences. My dissertation will combine movement ecology and population genetics to assess the ways in which seasonal migration has mediated life history trade-offs and impacted genetic diversity within species, with the goal of understanding how the risks of migration have translated to rewards over evolutionary timescales.",
