Corporate Taxation, Agglomeration and FDI : Firm Level Evidence for Belgium

The results reveal that investments are sensitive to changes in fiscal policy, with an average tax sensitivity of around -1.5. We also pick up an effect of agglomeration economies: a regional increase in the number of own industry firms dampens tax sensitivity
