Minimum wage

A minimum wage is the lowest amount an employer can legally pay an employee. It acts as a price floor for labor. This means workers cannot sell their labor for less than this specific rate. Most countries in the world have established minimum wage laws by the end of the 20th century. These policies can vary significantly between different nations. They can even change within a single country based on specific regions or industries.

Governments use several methods to implement these pay rules. Some jurisdictions pass laws that name a specific dollar amount directly. Other systems use a formula to adjust the wage based on economic indicators like inflation. Some places establish wage boards to determine rates. These boards include representatives from the government, employers, and employees. This consultation helps balance the needs of all parties involved. Rates may also vary by age group or specific job sectors.

History shows that wage laws have evolved from setting maximums to setting minimums. In 1349, King Edward III issued the Ordinance of Labourers in England. This decree actually set a maximum wage for laborers. It followed the Black Plague, which decimated the population in 1348. The resulting labor shortage caused wages to rise rapidly. To counter this, the King set a wage ceiling. Later, the Statute of Labourers in 1351 increased penalties for paying more than the set rates. By 1389, an amendment fixed wages to the price of food. In 1604, King James I formalized pay for textile workers.

The modern movement for minimum wages began to address worker exploitation. In the late 19th century, many people worked in sweatshops. These manufacturing environments often employed women and young workers. Owners were thought to have unfair bargaining power over these employees. This led to substandard wages and poor conditions. The first modern national minimum wage laws were passed in New Zealand in 1894. Australia followed in 1896. The United Kingdom passed such laws in 1909. In the United States, national statutory minimum wages arrived in 1938.

Today, more than 90 percent of countries have legislation or collective bargaining regarding minimum wages. In the European Union, 21 out of 27 member states have national minimum wages. Some countries, like Sweden and Denmark, do not have national laws. Instead, they rely on trade unions and employer groups to set earnings. Rates differ greatly across the globe. For example, the U.S. federal minimum wage is $7.25 per hour. However, Washington state has a rate of $16.28 per hour. In the United Kingdom, the rate is £11.44 for those aged 21 and older. India has a very complex system with over 1,200 different rates. In Mumbai, the rate was Rs. 348 per day in 2017.

Economists use different models to study how these laws affect the market. The supply and demand model suggests that higher wages may decrease employment. As labor becomes more expensive, firms may demand fewer hours or fewer workers. This is because the cost of doing business increases. However, other models look at monopsony scenarios. A monopsony occurs when a single employer has significant power over the market. In these cases, minimum wages can actually increase labor market efficiency.

There is a significant debate regarding the impact on poverty and inequality. Supporters argue that higher wages improve standards of living. They believe it reduces poverty and boosts worker morale. They also suggest it can create a ripple effect for higher earners. Opponents argue that increases can lead to unemployment. They worry that low-skilled workers may be unable to find work. Some businesses might respond by automating job functions or using gig workers. A 2025 study of California's fast-food sector showed a decline in employment following a wage increase. The study estimated a loss of roughly 18,000 jobs that would have otherwise existed.
