How Do Labor Markets Work?

How do labor markets work? Employers demand labor and people supply it, and wages, hours and conditions are the price that pulls the two toward balance. Unlike goods markets, the adjustment is slow and uneven: jobs and workers differ, information is incomplete, and a match takes time to find. Job postings are the demand side made visible.

How labor markets work, piece by piece

1. Demand. Employers want labor because of what it produces, so demand for workers follows demand for the firm’s goods and services. It shows up as openings, hires and job postings, and it falls first in the functions a firm can pause.
2. Supply. People decide whether to work, how many hours, in which occupation and where. Supply is measured by participation, the labor force and unemployment, and it moves with pay, childcare, health, migration and demographics.
3. Wages adjust slowly. Pay is set by contracts, norms and posted ranges, and employers rarely cut it outright. So when demand falls, hiring slows and openings close before wages move, and when demand rises, wages for new hires move before wages for everyone.
4. Frictions and matching. A vacancy in nursing does not absorb an unemployed software engineer. Search costs, geography and skill mismatch mean openings and unemployment coexist; economists read their ratio and the relationship between them as the health of matching.
5. Tight and loose. A tight labor market has many openings per job seeker, a high quits rate and rising pay for new hires. A loose one has the reverse: long searches, few openings, low quits. Both are read from the same handful of series.
6. Segmentation. There is no single labor market. Occupation, industry, region and seniority each have their own balance, and a national figure hides opposite moves within it. The plain-language overview is in what is the job market.

Postings fit as a measure of demand. A posting appears when hiring intent forms, weeks before a hire is counted in official statistics, and it carries the occupation, location, seniority and skills the employer wants. The limits are real: postings cover employers who advertise, each board has its own employer mix, and a posting is intent rather than a hire. Read them for direction and composition, and read official statistics for levels. The Labour Market Pulse publishes the occupation and industry composition of live postings monthly.

Where JobsPipe fits

JobsPipe is a jobs data API that collects live postings from LinkedIn, Indeed, Y Combinator, Naukri, Workday, Greenhouse, Workable, SmartRecruiters, Ashby, Lever and Paylocity, returns them as one schema with closure tracking and a ghost score, and includes a free tier of 1,000 jobs a month. The segmentation step above is built in: cut demand by occupation with occupation_code_or, by industry with isic_division_or, by country with job_country_code_or and by employer size with min_employee_count and max_employee_count. The published aggregates are documented on the labour market API page.
