The Impact of Minimum Wage on Employment and Poverty
Quick fact
Some studies find that a 10% increase in minimum wage reduces employment by only 1-2%, while others find no effect.
Why this is interesting
You've probably heard that raising the minimum wage helps workers—but what if it actually costs some of them their jobs?

Understanding The Impact of Minimum Wage on Employment and Poverty
Imagine a market where labor is the product and workers are the suppliers. The minimum wage acts like a floor set above the market-clearing price. Before the floor, equilibrium wages balance supply and demand. When the floor is raised, the wage becomes more expensive for employers. In a simple model, employers hire fewer workers because the cost of each worker rises. But real life is more complex: employers might pass costs to consumers, adopt automation, or absorb profit cuts. The size of the effect depends on how responsive employers are to wage changes—called the elasticity of labor demand. If demand is inelastic, employment doesn't drop much. Cross-country studies and before-and-after comparisons show that modest minimum wage increases rarely cause big job losses, but very high increases (like Seattle's $15) can reduce hours. Poverty is also tricky: a minimum wage worker might be a teenager from a middle-income family, so the policy may not target the poor effectively. Meanwhile, for a single parent earning minimum wage, an increase can lift them above the poverty line. The net effect on poverty is thus mixed and depends on who actually earns it.
A deeper explanation
The standard textbook model predicts that a binding minimum wage creates a surplus of labor (unemployment) because quantity supplied exceeds quantity demanded. This is because the wage is set above the equilibrium. However, the model assumes perfect competition and identical workers. In reality, labor markets are often monopsonistic—a single employer has market power and can set wages below the competitive level. In such cases, a moderate minimum wage can actually increase employment because it offsets the monopsony's exploitation, moving the wage closer to equilibrium. Empirically, David Card and Alan Krueger's famous 1994 study of fast-food restaurants in New Jersey found no employment loss after a wage increase, sparking a major debate. Meta-analyses show that the employment elasticity is small, often around -0.1 to -0.2, meaning a 10% wage increase reduces employment by only 1-2%. Beyond employment, the poverty impact is limited because many minimum wage earners are not in poor households. Moreover, some workers may see reduced hours or lose other benefits. Thus, the policy's effectiveness depends on the wage level, the economic context, and the specific workers it reaches. Understanding this trade-off is crucial for evaluating real-world policy proposals, such as the Fight for $15 campaign, which often cites moral arguments but must confront economic evidence.
