Such an increase in output will show up in growth in the short run that will be higher than the potential growth rate of the economy. Such a short-term growth acceleration can be attained when there is an under-utilisation of resources. If there is a great deal of slack in the economy, then increased spending can raise the level of output.
However, both the level and the growth rate of production are limited by the supply and quality of productive resources. If the employable resources are of poor quality, then output cannot increase unless there is a strong increase in the productivity of the resources already being used.
