<strong>CAPRI</strong><br />

Digression on yield endogeneity<br />

<strong>CAPRI</strong><br />

• Yields are currently fixed (per technology)<br />

• Nonlinearities in <strong>crop</strong> production are due to PMP only<br />

• If input use and yield were endogenous, non-linearity<br />

could be “lifted out <strong>of</strong>” <strong>the</strong> PMP-terms and “explained”<br />

• Model results could be richer: intensity<br />

• Pre-test 1: endogenous input use<br />

• Pre-test 2: yield-acreage dependence<br />
