Resources

Things I share with students and collaborators: how to find a predoc, AI tools for research, useful datasets, and research tools and guides.

Predoc Tips

Sources for finding predoctoral and RA positions

This list is not exhaustive, but it’s a good place to start.

A hub of predoc resources. Predoc.org collects useful materials, including practice coding tasks and a newsletter with advertised positions.

Sites that aggregate many postings

  • NBER posts non-NBER RA positions here, and advertises some directly here.
  • Professors and others tag relevant RA postings on the @econ_RA Twitter/X page (no account needed to read).

Organized predoc programs with a set hiring cycle

Programs for US citizens and/or permanent residents only

AI Tools

I ran a hands-on workshop for economists at UCSD on Claude Cowork + Code. The session covered using AI tools in economics research: writing and editing Stata, R, and Python, integrating results into Overleaf, and keeping projects and replications organized, with live examples. Slides and the workshop thread:

A shorter follow-up on permissions: the difference between Manual and Auto mode, and why version controlling with git and/or Dropbox does more of the safety work than the permission prompt.

Data

Datasets you may find useful to explore geo-spatial and/or mental-health-related research ideas.

Geospatial data for development & urban research

Publicly available spatial and satellite data for development and urban research:

TopicDatasetGeographic unitsTime coverageKey variablesSpatial dataAccess
Settlement & populationGHS - Global Human Settlement Layer (JRC / Copernicus)Global grid (100 m - 1 km); GHS-UCDB city polygons1975 onward, in epochsBuilt-up surface (GHS-BUILT), population (GHS-POP), settlement model / degree of urbanization (GHS-SMOD), consistently delineated cities (GHS-UCDB)Rasters; UCDB as vector polygonsFree, open
Household surveys + GPSDHS - Demographic and Health SurveysSurvey clusters, country1985 onward, repeated cross-sectionsHealth, fertility, and wealth microdata; geospatial covariates such as night lightsRandomly displaced GPS cluster coordinatesFree, registration; GPS needs a short access request
Economic activity proxyNight lights - VIIRS & DMSP (Earth Observation Group)Global grid (VIIRS ~500 m; DMSP ~1 km)DMSP 1992-2013 (an extension series runs to 2019); VIIRS 2012 onwardNighttime radiance, a standard proxy for local economic activityRastersFree, but bulk downloads now need an EOG account; also on Google Earth Engine
Urban extent, from night lightsAnnual urban extents - Zhao et al. (2022), paperGlobal grid, ~1 km1992-2020, annualBinary urban / non-urban maps built from harmonized night lights (DMSP-OLS through 2013, VIIRS-derived after). Note this is a core-urban-domain concept, not a Landsat impervious-surface product like GAIA, so the two are not drop-in substitutesRastersFree, open (CC BY 4.0)
Gridded GDPKummu et al. - gridded GDP & HDIGlobal grid, 5 arc-min (~10 km); the update also gives 30 arc-sec and admin-level polygons1990-2015, annual; the 2025 update runs 1990-2022GDP per capita PPP, total GDP, HDI. The 2025 update extends GDP per capita and downscales to admin-2, but drops HDI, so for gridded HDI you still need the 2018 releaseNetCDF; update adds gpkg and CSVFree, open (CC BY 4.0)
Gridded GDPLocal GDP estimates - Rossi-Hansberg & Zhang (2026), paperGlobal cells at 1, 0.5, and 0.25 degrees2012-2022, annualPredicted local GDP with uncertainty bounds, from a random forest on population, night lights, land use, emissions, and vegetation. Predictors reach beyond night lights, which helps if night lights are your regressorShapefiles + CSVPublic; no explicit license stated

Census microdata + boundariesIPUMS InternationalHarmonized GEOLEV1 / GEOLEV2 (consistent over time) and unharmonized year-specific admin units1960 onward, census roundsCensus microdata linked to boundaries; IPUMS USA does the same for the USGIS boundary filesFree, registration

Working with night lights. Matt Lowe’s Night Lights and ArcGIS: A Brief Guide (2014) walks from the raw downloads to an analysis-ready dataset, covering clipping, gas-flare removal, and projections. The ArcGIS workflow still holds; its data links predate the move to the Earth Observation Group, so pair it with the VIIRS and DMSP links above. (Linked via the Internet Archive: the original MIT URL now 404s.)

Aggregated catalogs. The UPenn Libraries GIS guide (global and US spatial data) and the geo4.dev data catalog (development-focused) list many more sources.

Mental health data

Publicly available datasets with a validated mental-health or wellbeing measure, plus a few open-replication economics papers and speech/audio depression corpora; free with registration unless a restricted/paid flag is noted. Sleep has its own section below, though the survey tables here also note what sleep each dataset collects.

Detecting depression from speech / audio - public corpora, mostly from the speech-ML and clinical communities (I found no economics study that has released audio-based depression data):

  • DAIC-WOZ / E-DAIC (USC). Field-standard English corpus: clinical interviews, audio + transcripts, PHQ-8 labels (the AVEC benchmark). Free but restricted (signed application, institutional email).
  • Androids Corpus. Italian speech (reading + interview), clinician diagnoses; open direct download (academic terms).
  • EATD-Corpus. Chinese speech + text with SDS depression labels; open download.
  • MODMA (Lanzhou). Audio (+ EEG), clinical MDD diagnosis; free but account + agreement.
Sleep data

Sleep measured objectively (actigraphy, wearables, polysomnography) alongside self-report, plus the economics field experiments that have collected it. For sleep items inside the large mental-health panels (IFLS, MxFLS, Add Health, HRS, Understanding Society, and others), see the survey tables in the mental health section above.
