The US Experience Since 1945
Chapter 9: Verification of the Immigrant–Trade Link
In this and the following chapter, results obtained when estimating equation (8.5) and variants of the baseline estimation equation are presented and discussed. We begin by verifying an immigrant–trade link between the US and the full set of home countries examined in this study. This also involves examination of the robustness, in terms of sample composition and econometric specification, of this primary result. We then turn our attention to variation in the influences of immigrants across entry classifications and in terms of the average length of stay in the US and the skill composition of immigrant populations, before finally considering in greater detail the effects of cultural distance and its component dimensions on US–home country trade flows and the corresponding connection to immigrants’ pro-trade influences. 9.1 THE INFLUENCE OF IMMIGRANTS ON US–HOME COUNTRY TRADE To determine whether an immigrant–trade links exists for the US and the 66 home countries for which complete data are available, three econometric specifications have been estimated using both aggregate exports and imports, in turn, as the dependent variable. The estimation results are presented in Table 9.1. Results obtained when estimating our baseline specification are provided in columns (c) and (f). Since natural logarithms have been taken for each of the dependent variable series, estimated coefficients on explanatory variables that also have been transformed into logarithms can be interpreted as elasticities. This is to say that the coefficients represent the expected proportional change in the respective dependent variable that would result from...
