Measuring Preemptive Investment
Shaffer 1993 Perceived MR MRp=P + λh(Q, Y, α) λ=0 perfect competition λ>0 market power & underproduction λ<0 “supercompetition” and overproduction
15
Estimation Q = α0 + α1P + α2Y + α 3 PZ + α 4 Z + α 5 PY +α 6YZ + ε
P = -λQ/(α1 +α3 Z + α5Y) + (C/Q)(ß1 + ß2 ln Q + ß3 ln W1 + ß4 ln W2) + ξ P = -λQ/(α1 +α3 Z + α5 Y) + (C/Q)(ß1 + ß2 ln Q + ß3 ln W1 + ß4 ln W2)- ß5 DQ/(α1 +α3 Z + α5Y) + ξ
