 · Studenmund defines 2SLS as ''a method of systematically creating instrumental variables to replace endogenous variables where they appear as explanatory variables in simultaneous equation systems.''. Stage 1: Run OLS on (3) and (4) to get estimates z 1 and z 2 for Y 1 and Y 2 respectively. Stage 2: Run OLS on (1) and (2) using instruments z 1 ...

Introduction The concept of instrumental variables was first derived by Philip G. Wright, possibly in co-authorship with his son Sewall Wright, in the context of simultaneous equations in his 1928 book The Tariff on Animal and Vegetable Oils. In 1945, Olav Reiersøl applied the same approach in the context of errors-in-variables models in his dissertation, giving the method its name.
