Statement for the Record
of David Bier of the Cato Institute[1]
Submitted to Subcommittee on Immigration and Border Security,
House Committee on the Judiciary 
Hearing on
“Agricultural Guestworkers: Meeting the Growing Needs of American Agriculture”
July 18, 2017

Foreign agricultural workers allow farms to expand production, lower prices, and raise incomes for most workers in the United States. Government intervention in the labor market inhibits the ability of farmers to plan the planting and harvesting of crops appropriately, leading to a reduction in production at the start of the season or crops rotting at the end. This government-created uncertainty also makes it more difficult for U.S. companies that rely on U.S. agricultural products to expand. At the same time, unnecessary regulations on agricultural guest workers limit their availability, incentivizing illegal immigration.

To fix these problems and end the regulatory uncertainty, Congress should grant a lawful status to the existing unauthorized immigrant workforce—a disproportionate share of which works in agriculture—and it should reform the current H-2A temporary worker program for future agricultural workers. Excessive regulatory costs and arbitrary limitations on the occupations that H-2A workers may perform limit the use of the program. Any revised H-2A program should allow guest workers to change employers without ex ante government permission and to freely negotiate wages or other benefits without fear of losing their status.

Foreign Agricultural Workers Increase Farm Production

Labor costs account for 17 percent of the variable costs for production on U.S. farms.[1] For fruits, vegetables, and nursery products, the price of labor can account for almost half of all variable costs.[2] All else equal, increases or decreases in the supply of labor result in increases or decreases in production. Higher production has many salutary consequences for the United States, including increased returns on investment, lower food prices, and increased employment.[3]

In 2013, a team of economists employed by the U.S. Department of Agriculture (USDA) estimated that a guest worker program that boosted the number of total temporary workers by 156,000 over 15 years would raise production by up to 2 percent annually in certain labor-intensive subsectors.[4] By contrast, a removal of 5.8 million unauthorized immigrants would decrease agricultural output in certain subsectors by up to 5.4 percent. A similar study found that a 50 percent reduction in foreign workers in the dairy industry would reduce output by 7.9 percent.[5]

Farmers reduce planted acreage when they cannot hire as many workers as they would like to. As the immigration attorney for one farm put it in March 2017, “You’re either reducing your acreage or you’re going for H-2A.”[6] Farmers who miscalculate end up having crops rot in the field. One study found that California fruit and vegetable farmers had to plow under $13 million worth of produce in 2016, a threefold increase since 2011, due to unexpected labor scarcity.[7]

Machines Cannot Fully Replace Human Laborers

Over the last several decades, the price of machinery has fallen relative to the wages of farm laborers.[8] This has led many farms to hire fewer workers and shift to machines. Although opponents of opening the international labor market sometimes argue that the shift to machines proves that foreign labor is unnecessary, this is incorrect for several reasons.

Many industries simply cannot mechanize production at this time. Many fruits and vegetables need to be harvested by hand. The USDA has concluded that some of these sectors, such as apples, oranges, and asparagus, that compete internationally would lose market share if labor costs rise.[9] Even in sectors that can adopt machinery, however, USDA concluded that “hand-harvested produce is usually of better quality, since it is hard to replicate the skill and care of hand harvesters.”[10] This means that a scarcity-inducing labor market policy also harms consumers by diminishing quality. 

Even if increased labor scarcity induced farmers to replace labor with machines, this would defeat the stated purpose of the tighter labor policy: better wages for U.S.-born farm workers. A major justification for the 1965 termination of the Bracero guest worker program for Mexican farm workers was that it would raise wages for American farmworkers. An excellent recent study, however, found that farm wages in Bracero-heavy areas actually did not rise relative to those in other areas after its cancellation.[11] The authors concluded that farmers responded to the increased labor scarcity with mechanization, not with higher wages. 

Foreign Farmworkers Don’t Harm Americans

Guest workers rarely displace domestic farmworkers. Another recent study that analyzed data from the North Carolina Growers’ Association (NCGA) proves this point. NCGA advertised 6,500 farm jobs and accepted 90 percent of all applications from U.S. residents, which amounted to just 245 U.S. residents accepting a job in the field out of a total of 500,000 unemployed North Carolinians.[12] Of these, only seven actually finished the growing season. This is compared to 90 percent of the more than 6,000 H-2A workers who finished.[13] This coincides with a study of California vegetable producers that found at most one U.S. resident is displaced from a farm job for every 81 foreign farm workers.[14]

Even though foreign farm workers may displace a tiny percentage of U.S. workers from farms, this does not necessarily do permanent long-run economic damage. Immigrant farm workers enable U.S. workers to move into related industries where higher pay is available. As foreign farm workers have entered, U.S. workers have moved to other industries, which explains their lack of interest in agricultural jobs. Indeed, U.S. workers make up the vast majority of workers in occupations that depend on manual agricultural labor, such agricultural managers and supervisors, agricultural inspectors, purchasing agents for farm products, and others.[15]

For this reason, increases in the availability of farm labor ultimately benefit U.S. workers elsewhere in the economy. USDA used a general equilibrium model to estimate the effect of removing 5.6 million unauthorized immigrant workers and concluded that about 1 percent of income accruing to natives is dependent on those workers, a disproportionate share of whom work in agriculture.[16]

The Supply and Demand for Farmworkers

Employment figures indicate that agricultural workers are currently in high demand. Farm unemployment is usually higher than the national average because the work is often seasonal or temporary, but unemployment in agriculture over the last 12 months is as low as it has been during any period in a decade.[17] August 2016 saw the lowest unemployment rate for that month since before the year 2000, as did February and March 2017. Average unemployment for the last 12 months was the lowest of any 12-month period since 2007.[18]

Few economic sectors in the United States rely more heavily on foreign workers than agriculture, meaning that immigrants are responsible for a large portion of its production. The USDA has found that more than 70 percent of hired crop farmworkers migrated to the United States from other countries.[19] It also found that half of the total lacked proper authorization to live or work in the United States.[20] In addition, another 135,000 foreign workers received H-2A visas in 2016 to come and work as temporary farm workers in the United States.[21] The use of this program has increased substantially over the last two decades, doubling in the last five years alone (Figure 1).[22]

This increase in the supply of guest workers is beneficial, not only due to the positive economic factors described above, but also due to the positive impact on border security. Over the last 60 years, guest worker entries correlate negatively with apprehensions of illegal aliens at the border. Logically this relationship makes sense. Government has artificially restricted the supply of a service below the level of market demand. The excess demand seeks an outlet in the underground economy. The United States experienced a similar process during alcohol prohibition with bootleggers replacing the legitimate liquor market. When Congress first enacted immigration quotas in the 1920s, many commenters at the time noted the relationship between these two progressive policies, calling illegal immigration “human bootlegging.”[23]

Figure 2 highlights this relationship for the post-World War II period. The red line is the number of guest workers entering each year. The blue bars represent the number of apprehensions that each border agent made during the year, which is the best measure of total illegal immigration available. Typically, more apprehensions per agent mean more attempted crossings. As it shows, when illegal immigration first started in the late 1940s, Congress responded to the market, increased the supply of visas, and continued to do so until the supply met demand. Combined with a stricter enforcement policy in the 1950s, the problem nearly evaporated, but it returned with a vengeance after Congress eliminated the Bracero program in 1965.[24]

In recent years, the number of guest workers entering each year has risen sharply, which again has coincided with a drop in illegal immigration, but the H-2A program still needs reforms. From 2007 to 2011, H-2As represented just 10 percent of farm employment.[25] Although it has doubled in size since then, it is still a small share of the total. The biggest problem is that H-2A workers may not work in any permanent or non-seasonal jobs. This eliminates roughly half of all farm jobs, including in the dairy and livestock industries. H-2A visas are also unavailable for meat and poultry processing. The H-2A program is unworkable for certain seasonal industries that cannot guarantee a certain length of employment as the program requires. USDA also notes that the inflated wage requirements may discourage some employers from using it.[26]

An expanded agriculture guest worker program would benefit the U.S. economy and improve border security. Foreign farm workers are in demand and Congress should allow the free market, rather than the black market, to meet that demand.
