Job Displacement and Household Consumption Patterns: Evidence from South Korea
Using representative household-level data from South Korea, this study demonstrates that job displacement significantly reduces spending on essential and flexible categories like food and allowances, as well as communication expenses, while leaving large fixed commitments such as housing and vehicle costs unchanged.

When a person loses their job, the immediate financial shock is obvious: the paycheck stops. But the story of what happens next is far more complex than a simple line going down. Economists have long known that when income drops, families spend less. Yet, the real question is not just how much less, but where the cuts happen. Do families stop buying groceries? Do they cancel their internet service? Or do they keep paying for a house they can no longer afford, perhaps by draining their savings or borrowing money? Understanding these choices is vital because it reveals how families survive a crisis. It shows which parts of daily life are flexible enough to shrink and which parts are so heavy or fixed that they cannot be moved, even when the money runs low. This delicate balancing act determines whether a family simply tightens its belt or faces a deeper, long-term struggle.
Researchers Janghyeok An and Changyeon Jung set out to map this terrain using a unique window into the lives of South Korean families. They analyzed decades of detailed records from the Korean Labor and Income Panel Study, a massive survey that tracks thousands of households year after year. Their focus was on the specific moment when a primary breadwinner—the person who usually earns the most in the family—loses their job through no fault of their own, such as a factory closing or a mass layoff. By comparing these families to others who did not experience such a shock, the team could see exactly how spending patterns shifted in the years before and after the event. They looked at everything from food and housing to entertainment and medical bills, breaking down the household budget into its smallest pieces to see which ones were cut first.
The results paint a clear picture of how families adapt. When the primary earner lost their job, the family's total monthly income dropped by about 13 percent in the first year. This was a significant blow, yet the total amount the family spent on everything combined fell by a much smaller margin, only about 4 percent. This gap suggests that families are not just cutting spending; they are also dipping into savings, taking on debt, or relying on income from other family members to keep the lights on. However, the way they cut their spending was not random. They did not slash their entire budget evenly. Instead, they made very specific choices about what to reduce and what to keep.
The most immediate cuts came from categories that are easy to adjust. Spending on food bought at home, like groceries, dropped by roughly 3 percent. Families also reduced their spending on communication services, such as phone and internet bills, by about 3.7 percent. These are flexible costs; a family can choose to cook cheaper meals or switch to a cheaper phone plan almost immediately. Similarly, the money given to family members for personal use, known as allowances, shrank by about 6 percent. This category, which covers small, non-essential purchases, was another area where families felt free to pull back. Even spending on entertainment and leisure showed a tendency to decline, though the data was not strong enough to be certain.
In stark contrast, the big, fixed commitments remained untouched. The study found no evidence that families reduced their spending on housing or vehicles in the year following a job loss. This is partly due to the unique way housing works in South Korea. Many renters there use a system called jeonse, where they pay a massive lump sum of cash upfront to a landlord instead of monthly rent. Because this deposit is returned when the lease ends, the monthly cost of housing can be zero. Even if a family loses their job, moving to a different apartment to get that deposit back is difficult and expensive, so they often stay put. Similarly, spending on education and healthcare did not change significantly. Education in South Korea is often viewed as a critical investment in a child's future, and families are reluctant to cut these costs. Healthcare costs also remained steady, likely because the national health insurance system continues to cover the family regardless of employment status, making these expenses feel fixed and unavoidable.
The researchers also looked at whether the job loss of a secondary earner, such as a spouse, had the same effect. They found that while it did cause some changes, the impact was much smaller than when the primary breadwinner lost their job. This confirms that the main earner's income is the anchor of the household budget, and its loss triggers the most drastic adjustments. The study also checked if the type of job loss mattered, comparing those who were laid off from a specific department to those whose entire factory closed. The results were consistent across these groups, reinforcing the idea that the pattern of cutting flexible costs while holding firm on fixed ones is a reliable response to financial shock.
Ultimately, the study reveals that when a family faces a sudden loss of income, they do not simply stop spending. They become strategic. They protect the large, immovable pillars of their life—the roof over their head, the education of their children, and their health—while quietly shrinking the smaller, more flexible parts of their daily routine. They cut the grocery bill, the phone plan, and the allowance for personal treats. This behavior highlights a fundamental truth about household economics: some costs are rigid, locked in by contracts or deep cultural values, while others are fluid and can be squeezed to survive a storm. The findings suggest that social safety nets, like unemployment insurance, need to understand these specific vulnerabilities. If a family is already cutting its food budget to keep its housing, a policy that helps with rent might be less effective than one that helps with groceries. By seeing exactly where the cuts happen, we gain a clearer view of how families endure the hardest days of their lives.
