Recent empirical work shows large consumption responses to house price movements. This is at odds with a prominent theoretical view which, using the logic of permanent income hypothesis, argues that should be small. We show that, in contrast this view, workhorse models incomplete markets calibrated rich cross-sectional micro facts actually predict responses, line data. To explain result, we shocks can approximated by simple and robust rule-of-thumb formula: marginal propensity consume out...
Abstract We provide evidence on the relationship between aggregate uncertainty and macroeconomy. Identifying shocks using methods from news literature, analysis finds that innovations in realized stock market volatility are robustly followed by contractions, while to forward-looking have no significant effect economy. Moreover, investors historically paid large premia hedge but not implied volatility. A model which fundamental skewed left can match those facts. Aggregate matters, it is...
We develop, estimate, and test a tractable general equilibrium model of oligopsony with differentiated jobs concentrated labor markets. estimate key parameters by matching new evidence on the relationship between firms’ local market share their employment wage responses to state corporate tax changes. The quantitatively replicates quasi-experimental imperfect productivity-wage pass-through strategic setting dominant employers. Relative efficient allocation, welfare losses from power are 7.6...
Abstract Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals produce any offspring (fertility), or number produced fertile (fecundity). This has important ecological consequences, because reproduction is ultimate measure population fitness: a reduction in reproductive output lowers growth rate and increases extinction risk. Despite this importance, there have been no large‐scale summaries evidence for effect temperature on...
Abstract Climate change is affecting population growth rates of ectothermic pests with potentially dire consequences for agriculture and global food security. However, current projection models pest impact typically overlook the potential rapid genetic adaptation, making forecasts uncertain. Here, we predict how climate adaptation in life-history traits insect affects their on agricultural yields by unifying thermodynamics classic theory resource acquisition allocation trade-offs between...
1 Large female insects usually have high potential fecundity. Therefore selection should favour an increase in body size given that these females get opportunities to realize their advantage by maturing and laying more eggs. However, ectotherm physiology is strongly temperature-dependent, activities are carried out sufficiently only within certain temperature ranges. Thus it remains unclear if the fecundity of a large fully realized natural environments, where thermal conditions limiting. 2...
Are there times when durable spending is less responsive to economic stimulus? We argue that aggregate expenditures respond more sluggishly shocks during recessions because microeconomic frictions lead declines in the frequency of households' adjustment. show this by first using indirect inference estimate a heterogeneous agent incomplete markets model with fixed costs adjustment match consumption dynamics PSID microdata. then aggregating delivers an extremely procyclical Impulse Response...
Intralocus sexual conflict (IaSC) occurs when selection at a given locus favors different alleles in males and females, placing fundamental constraint on adaptation. However, the relative impact of IaSC adaptation may become reduced stressful environments that expose conditionally deleterious mutations to selection. The genetic correlation for fitness between females (rMF) provides quantification across genome. We compared benign (29°C) (36°C) temperature by estimating rMFs two natural...
Many public health interventions provide benefits that extend beyond their direct recipients and impact people in close physical or social proximity who did not directly receive the intervention themselves. A classic example of this phenomenon is herd protection provided by many vaccines. If these ‘spillover effects’ (i.e. ‘herd effects’) are present same direction as effects on intended recipients, studies only estimate will likely underestimate full intervention. Causal inference...
How much ability does the Fed have to stimulate economy by cutting interest rates? We argue that presence of substantial debt in fixed-rate, prepayable mortgages means rates depends not just on their current level but also previous path. Using a household model mortgage prepayment matched detailed loan-level evidence relationship between and rate incentives, we recent paths will generate headwinds for future monetary stimuli.

The evolution of male traits that inflict direct harm on females during mating interactions can result in a so-called tragedy the commons, where selfish strategies depress population viability. This commons be magnified by intralocus sexual conflict (IaSC) whenever alleles reduce fecundity when expressed spread because their benefits males. We evaluated this prediction detailed phenotyping 73 isofemale lines seed beetle Callosobruchus maculatus. quantified genetic variation life history and...
ABSTRACT We study temporary fiscal stimulus designed to support distressed housing markets by inducing demand from buyers in the private market. Using difference‐in‐differences and regression kink research designs, we find that First‐Time Homebuyer Credit increased home sales 490,000 (9.8%), median prices $2,400 (1.1%) per standard deviation increase program exposure, transition rate into homeownership 53%. The policy response did not reverse immediately. Instead, comes several years future:...
The degree to which developmental biases affect trait evolution is subject much debate. Here, we first quantify fluctuating asymmetry as a measure of variability, i.e., the propensity systems create some phenotypic variants more often than others, and show that it predicts standing genetic variation well deep macroevolutionary divergence in wing shape sepsid flies. Comparing our data findings previous study demonstrates variability fly Sepsis punctum strongly aligns with mutational, genetic,...

We study the association between order flow and exchange rate returns in five years of high-frequency intraday data from leading interdealer electronic broking system, EBS. While has been studied several previous papers, these have mostly used relatively short spans daily older bilateral dealing systems and, usually, transaction counts instead actual trading volume. Using a substantially longer span recent measuring as signed volume, we find strong positive at frequencies ranging one minute...
Summary It has been postulated that climate warming may pose the greatest threat species in tropics, where ectotherms have evolved more thermal specialist physiologies. Although could rapidly respond to environmental change through adaptation, little is known about potential for especially tropical species. In light of limited empirical evidence available and predictions from mutation‐selection theory, we might expect genetic variance enable adaptation. However, as a consequence...
