Today in our PhD seminar Sydney Phiri presented an update on his work showing how measurement error can lead to the misclassification of demand- and supply-driven inflation, and proposed methods using disaggregated price data to improve real-time identification.

PhD student Mingkui Wen presented his research on whether Sweden's decision to avoid a strict nationwide COVID-19 lockdown led to worse health outcomes, finding that while short-run outcomes were worse, these differences largely disappeared over a longer 1,000-day horizon.

Our PhD student Pakasa Bary has presented his research on estimating the wage Phillips curve using occupations rather than regions as the panel dimension, showing that following the pandemic, the wage-unemployment relationship steepened more in telework-intensive occupations.

PhD student Zhuoran Du on how replication outcomes in economics compare with theoretical replicability identified by the meta-analytical tool “Z-curve”. Combining actual replication evidence with theoretical estimates provides a richer understanding of research credibility.

We enjoyed this so much we’re going to have to break out the heart eyes emoji on the job: 😍😍😍 Great job @olihanney.bsky.social and our own @economeager.bsky.social !

🆕 Aggregating evidence, the research process, and empowering the public to understand research All that & more in this week's episode of Ideas in Development with @economeager.bsky.social. Really enjoyed discussing how we can improve the evidence base in economics by aggregating.

Our PhD student, Jacky Hsueh, presented a New Keynesian model with job-to-job search that he developed to investigate whether the surge in remote work following the pandemic affected the steepness of the Philips Curve in the United States.

Sydney Phiri presented a framework linking measurement error of inflation and output to misclassification of shocks as demand-driven or supply-driven and showed how misdiagnosis weakens the benefits of responding differently to demand versus supply inflation.

Sharunya Gnanasubramaniam presented her results from a field experiment which show that credible coordination can stabilise infrastructure maintenance under climate stress by sustaining cooperative beliefs and counteracting the material disincentives created by scarcity.

Today, our fantastic PhD student GVA Dharanan presented an early draft of his paper on efficiency in a private information multi-unit auction with externalities and the conditions under which this efficiency is achievable.
