For agriculture as a whole, factor supplies cannot be taken to be perfectly
elastic. In fact, the supply of most factors is fairly inelastic in the short run
and as such lead to inelastic supply. The relevance of the elasticity of the
factor supply can be inferred by comparing the fairly high supply elasticities
of individual crops with the low ones obtained from a direct estimation of
aggregate s~pply.~ While resources are fairly fixed for agriculture as a whole,
they can more easily be allocated among products.3
