[email protected]. Iehl: The Effects of Relative Wages and Border Enforcement on Illegal I The Effects of Relative Wages and Border Enforcement on Illegal Immigration Aaron Iehl* ABSTRACT. The flow of illegal immigrants into the United States cannot be accurately measured because any successful illegal immigrations will not be detected. This paper uses an apprehensions function developed by Hanson and Spilimbergo (1999) to estimate a lower bound for illegal immigration. An OLS regression model is employed to examine the effect of relative wages and border enforcement on the number of apprehensions at the U.S.-Mexico border from 1999-2017. These results are compared with findings from Hanson and Spilimbergo (1999) who studied apprehensions from 1976-1995. I. Introduction Since the creation of community there has been the concept of a border – a natural, physical, or social barrier that separates communities from one another.
