A neoclassical factor demand model for structures, equipment and labour is analyzed. It incorporates a variety of dynamic specifications, such as a multi-period time-to-build for structures, internal adjustment costs for each production factor, and external investment adjustment costs....

As large physical capital stock projects need long periods to be built, a time-to-build specification is incorporated in factor demand models. Time-to-build and adjustment costs dynamics are identified since by the first moving average dynamics, whereas by the latter autoregressive dynamics are...
