Empirical Evidence Exists On Sraffa Effects

As I have pointed out in the past, economists have discovered that, given standard neoclassical assumptions, competitive firms are sometimes willing to adopt a more labor-intensive technique at a higher wage. For some reason, you will have difficulty finding this possibility described in any textbook written by an author who is not self-consciously heterodox. Sometimes economists respond to this circumstance by asserting that no empirical evidence exists that technology can have the consequences highlighted by the sort of example I presented. This response has always seemed to me to be a non sequitur, as well as just mistaken.

I haven't read all the references I am about to mention. Not only do I not see how empirical evidence is relevant to a logical contradiction, I don't have the needed language skills:
"I have gathered that the most active discussion, both theoretical and empirical, on the how probable the occurence of reswitching is, has recently been taking place in the Italian language journals - one estimate puts the number of such papers in recent years to around seventy! I did not have access to any of them." -- Ahmad, Syed (1991). Capital in Economic Theory: Neoclassical, Cambridge, and Chaos, Aldershot: Edward Elgar: 250.
Empirical results that economists have explicitly connected to my favorite controversy in economics can be thought of as falling into three categories:
