How should police activity be deployed? We propose a model of criminal learning and estimate its parameters using RCT data from an anti-drunk-driving campaign in India. We find clear evidence of learning, making “rotating” checkpoints most effective www.econometricsociety.org/publications...

How should long-term employment contracts be regulated? We show that optimal regulation prices the use of non-competes, tying stronger non-competes to higher wages. This limits inefficient worker lock-in and raises pay at better matches. buff.ly/PD964cP

Academic research fuels applied innovation, but its commercial impact varies by location. Tracking researchers who move between universities, the study finds that place-specific factors account for 15–25% of geographic variation in commercial spillovers. buff.ly/aYENtuz

How do you get word of a new technology around a village? Asking randomly chosen farmers (not necessarily well-connected) to plant a new seed beside a familiar one reaches as many people as targeting central farmers. Demonstrations help word get around! buff.ly/w43xOpp

Burdett–Mortensen meets oligopsony — a general-equilibrium model of the labor market, with a finite number of large employers who post wages and compete for workers along the job ladder, solved in closed form. With an application to a US noncompete ban. buff.ly/eupuvUY

Why do many businesses in poor countries look overstaffed? Experiments in Uganda show employers and workers prefer redistribution via work to cash even for no-value tasks. Workfare-like incentives, reciprocity, and dignity shape firm size and productivity. buff.ly/AXDnHcj

Why are the wealthiest so wealthy? 27-year panel: top 0.1% wealth gap reflects higher saving (36%), inheritances (31%), returns (28%). Calibrated to cross-sections alone, models miss "New Money" or "Old Money"; our dynamic facts pin down the mechanism. buff.ly/1Z1N36N

When Jeff Bezos's Amazon stock doubles, should his tax bill? No, say Mark Aguiar, @benmoll.bsky.social and @florianscheuer.bsky.social: optimal taxes target realized net trades plus cash flows—not wealth or unrealized gains—while avoiding lock-in, whatever moves asset prices. buff.ly/vHUzTWr

Reanalyzing Suri (2011), we find instability in the parameter governing who benefits most from technology adoption, suggesting weak identification. We propose a group random coefficient approach to diagnose it & build robust CIs @econemilia.bsky.social @dghanem.bsky.social buff.ly/VzP1LwC

Can ML generate theoretical insight, not just predictions? Our procedures turn predictive models into anomaly generators, producing minimal cases existing theory can't explain. We apply it to revisit choice under risk. @sendhil.bsky.social @asheshrambachan.bsky.social buff.ly/F0ouzAV

We propose an algorithm for building efficient recentered IVs. While simulated IVs for Medicaid eligibility discard individual variation as non-random, our recentered IVs preserve it and deliver much more precise estimates. @instrumenthull.bsky.social, @borusyak.bsky.social buff.ly/H1JYjlX

95% of Amazon shoppers consider only the prominent "Buybox" offer—and Amazon's own offers are featured as often as similar offers priced 5% cheaper. Yet, as consumers prefer these offers, this article finds that the skew roughly maximizes consumer surplus. buff.ly/19zhXv1

How flexible are firms' input mixes in the long run? Using India's 1990s trade reforms, we estimate high substitutability across materials (elasticity ~2.5) and show input distortions cut output 3.5x more than prior work suggests. @Ale_M_Peter @cian_ruane buff.ly/fUpjXFr

Discrimination can persist as organizational trap: tackling it requires shifting beliefs across the hierarchy by trialing minority candidates. This is costly, so bias survives in firms, and standard tests fail as coworker bias depresses their performance. buff.ly/H5ruJPO

Can researchers estimate treatment effects precisely when covariates have measurement error or privacy-preserving noise? We show that repetitive (low-rank) covariates enable causal inference with the same precision as if the true covariates were observed. buff.ly/QcHd11D

What happens to insurance markets as genetic prediction improves? This article combines quantitative genetics, economic theory, and big data to study adverse selection and inform policy. Selection may become severe in critical illness insurance. buff.ly/Xf9ybyS

Buyers may differ not in value, but in purchase frequency. This changes dynamic screening: commitment extracts all surplus; without commitment, learning mitigates ratcheting and can make sellers screen after pooling. buff.ly/9z9y2db

When doctors lose control over the end users of their services — as with secondary markets for prescription drugs — most become more cautious. This can be helpful when overprescribing is rampant, but resale to misusers still causes harm. buff.ly/SnoMuMq

Random Priority—a popular no-transfer allocation mechanism—is efficient, fair, & simple to participate in. Is it the only mechanism with these properties? Marek Pycia @econ.uzh.ch and Peter Troyan, UVA Economics, answer this long-standing question in the positive. buff.ly/zlSjmC0

A structural model of applicant-examiner negotiation finds U.S. patent screening moderately effective, with social costs of $15.4bn/year. Examiner intrinsic motivation sharply improves screening quality, and capping negotiation rounds reduces social costs. @willmatcham.bsky.social buff.ly/W3Qciiu

Are you also torn between small sample performance and robustness to heteroskedasticity? You can have both! One can produce an exact test for subvectors that is asymptotically robust to heteroskedasticity. @guillaumeecon.bsky.social buff.ly/gIsdPs7

What securities emerge when competing investors design financing contracts? With dispersed information about common values, debt best protects investors from the winner’s curse and sellers’ informed selection—unlike in monopoly or private-value settings. buff.ly/g6q6D9Y

Why do workers dislike inflation? Because wages catching up to prices means costly conflict: tough pay talks, job search, bargaining. Survey + model show conflict more than doubles inflation costs. Joao Guerreiro, Jonathon Hazell, Chen Lian & Christina Patterson. buff.ly/S1GJdlV

When treatment locations are as-good-as-random, how do we estimate causal effects on nearby observations? Use counterfactual locations, known ex-ante or predicted via neural nets, and quantify uncertainty based on the quasi-experimental design. buff.ly/BFRhcFW

Gravity models usually make distance a shipping cost. What if distance also makes encounters between buyers and suppliers less likely? A new firm-to-firm matching model fits granular customs data and helps resolve trade and labor-market puzzles. buff.ly/XURqW3P

People underreact when inferring states, yet overreact when forecasting from the same signals. Fan, Liang & Peng show the question type triggers different heuristics—similarity between available and elicited statistics determines which shortcut dominates. buff.ly/ampbeNm

Why do richer economies have more very large firms? This paper shows that the upper tail of the firm size distribution thickens as economies grow. A model of idea search explains why, showing how growth itself can produce rising concentration. buff.ly/cpStCuc

Local projections are surprisingly robust to misspecification. By contrast, VAR confidence intervals with short-to-moderate lag length can severely undercover for misspecification that is small, difficult to detect, and cannot be ruled out a priori. buff.ly/c2obho2

How do anti-misinformation policies work? RCT & structural estimation on Twitter/𝕏 in the US: priming outperforms fact-checking by raising salience of reputation at low cost, curbing false news & preserving true news. Veracity updating matters less. buff.ly/Nr9JbFO
