Estimating Investment Functions Based on CointegrationL.SunauthorThe purpose of this chapter is to model both investment growth and cycle without artificially imposing a separation between them. This will be done by establishing both a long-run equilibrium investment level (adjustment) function and a short-run investment growth rate cycle (adjustment) equation based on the recently developed cointegration and error correction approaches.
