<p>holla9,</p>
<p>Off the top of my head, I can say that CalTech will require four semesters of math even for its econ majors.</p>
<p>And I have to make a subjective correction here. When econ is done “qualitatively,” it is still social science. When it is done “quantitatively,” it is still social science. Social science isn’t dependent upon whether or not you use mathematics to explain your model, but on whether or not your model is scientific to begin with.</p>
<p>Econ is always a social science, but a lot of undergrads get tripped up on the “liberal arts” label.</p>
