Cost-Push IO Price Models and Interaction with Quantities

In the Type I single-region, cost-push IO price model, under full competition, exogenous primary input price changes are fully passed on to all intermediate users that fully pass them on further, resulting in endogenous total and final output price changes. In the Type II interregional price model, additionally, consumption price changes are fully passed on in wage rates, while domestic export price changes are fully passed on to importing regions. Finally, it is shown how the IO price model may be combined with the IO quantity model by adding demand and supply price elasticities and how supply and demand shifts are passed on from market to market, resulting in lower, more realistic price and quantity multipliers.
