Analyze the impact of the 1980 Mariel Boatlift on the Miami labor market, focusing specifically on the wages of unskilled workers. Consider the contrasting conclusions reached by economists Giovanni Peri and Vasil Yasenov versus George Borjas regarding the effects of the influx of Cuban immigrants. Discuss the various factors that may account for these differing results, including differences in data selection, methodology, and interpretation. Additionally, explore Michael Clemens’ argument that, even if wages appeared unchanged, Borjas’ data would still have shown a decline post-1980, due to the way data is analyzed and interpreted in economic studies.

The influx of Cuban immigrants during the Mariel Boatlift in 1980 served as a significant case study in understanding the effects of immigration on local labor markets. The event brought approximately 125,000 Cubans to Miami, predominantly unskilled laborers, which, according to demand and supply theory, should have exerted downward pressure on wages for similar unskilled workers (Borjas, 1990). However, empirical evidence regarding this impact has produced divergent conclusions among economists, notably Giovanni Peri and Vasil Yasenov, and George Borjas. Understanding why these studies arrive at different results involves examining their underlying methodologies, data choices, and analytical frameworks.

Peri and Yasenov (2015) employed a comprehensive approach that leveraged extensive data sets and sophisticated statistical techniques to trace wage trends over time. They analyzed wages of low-skilled workers in Miami from the early 1970s through 1987, including the period surrounding the Mariel influx. Their methodology accounted for pre-existing trends in wages and utilized difference-in-differences analysis to isolate the effect of the immigrant wave. Their findings indicated that wages for low-skilled workers did not decline after 1980; in fact, wages slightly increased, although within a confidence interval that acknowledged some measurement uncertainty (Peri & Yasenov, 2015). This suggests that the immigrant influx did not harm native low-skilled workers, possibly due to factors such as labor market adjustments, increased demand for services, or complementarity between immigrant and native workers.

In contrast, Borjas (2017) focused on a different dataset and employed an alternative methodological approach that emphasized the potential bias introduced by the racial and skill composition of the sample. He argued that the Mariel immigrants were disproportionately unskilled and had a different racial composition than the native low-skilled workforce, which could distort wage estimates. Borjas’s analysis indicated a visible decline in wages for low-skilled workers following the influx (Borjas, 2017). His results were sensitive to the selection of data and the time period analyzed, emphasizing that different sample choices or adjustment periods could produce contrasting outcomes.

One key factor influencing these differing conclusions is the methodological approach — particularly how pre-existing wage trends and the composition of the samples are modeled. Peri and Yasenov's inclusion of comprehensive control variables and their emphasis on a broader sample helped mitigate biases that might exaggerate wage declines. Borjas, however, utilized a more restrictive sample, which was more susceptible to bias due to compositional differences. These differences reveal the importance of data selection and analysis techniques when interpreting the effects of immigration on wages.

Michael Clemens (2017) argued that even if the data showed no actual change in wages, Borjas’ methodology would likely still produce an apparent decline. This stems from the fact that measurement error, sample bias, and model specifications can bias estimates downward. Clemens pointed out that measurement uncertainty, especially given the variability of wage data, tends to produce confidence intervals that include a decline even when the true effect is zero. Thus, the observed wage decline in Borjas’s analysis could be an artifact of the employed econometric methods, sample biases, or model specifications. This highlights that conclusions about wage effects should be made cautiously, considering these inherent uncertainties (Clemens, 2017).

In conclusion, the contrasting results of Peri and Yasenov versus Borjas can be attributed to differences in data, methodology, and interpretation. While Peri and Yasenov's findings challenge the assumption that immigration depresses wages for unskilled native workers, Borjas's analysis underscores how methodological choices can influence results. Clemens's argument further emphasizes the importance of recognizing measurement and estimation biases in interpreting economic data. Taken together, these analyses illustrate the complexity of assessing immigration’s impact on wages and the necessity for careful, multi-faceted approaches in economic research.
