NBER Working Papers and Data API

Overview

The National Bureau of Economic Research (NBER) is the leading U.S. economics research organization, publishing 1,200+ working papers annually by top economists. NBER papers are among the most cited in economics. The website provides structured JSON API access to working papers and macroeconomic datasets. Free metadata access; some full text requires subscription.

API last verified: 2026-04-23. RSS feeds (/papers.rss) and the old query-param API (?q=... without /search path) are defunct. Use the endpoints below.

Working Papers Search API

Base URL: https://www.nber.org/api/v1/working_page_listing/contentType/working_paper

Search all papers

# Search working papers (returns JSON)
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/_/_/search?page=1&perPage=20&q=inflation+expectations"

# Get new-this-week papers (omit q for all recent)
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/_/_/search?page=1&perPage=20&newThisWeek=true"

# Find a specific paper by number
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/_/_/search?page=1&perPage=1&q=w33000"

Filter by program (path segment)

Program names go in the URL path (use + for spaces), replacing the two _/_ placeholders:

# Labor Studies papers
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/programs/Labor+Studies/search?page=1&perPage=20"

# Labor Studies + keyword search
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/programs/Labor+Studies/search?page=1&perPage=20&q=minimum+wage"

# Economic Fluctuations and Growth
curl "https://www.nber.org/api/v1/working_page_listing/contentType/working_paper/programs/Economic+Fluctuations+and+Growth/search?page=1&perPage=20"

API Response Structure

    {
      "title": "Paper Title",
      "authors": ["<a href=\"/people/john_doe\">John Doe</a>"],

Note on authors field: Values contain HTML anchor tags. Strip tags to get plain names:

import re
plain = re.sub(r'<[^>]+>', '', author_html)

Individual Paper Metadata (HTML meta tags)

For richer metadata on a single paper, parse <meta> tags from the paper page:

curl -sL "https://www.nber.org/papers/w33000" | grep 'citation_'
# citation_title, citation_author, citation_doi, citation_publication_date,
# citation_technical_report_number, citation_pdf_url

NBER Data Portal

# Business cycle dates (JSON, works directly)
curl "https://data.nber.org/data/cycles/business_cycle_dates.json"
# Returns: [{"peak": "2020-02-01", "trough": "2020-04-01"}, ...]

# CPS labor data extracts: https://data.nber.org/cps/
# Macrohistory database: https://data.nber.org/
