The Macro-Economic Impact of Changing the Rate of Corporation Tax. ESRI WP273. January 2009

This paper considers the impact of changes in the rate of corporation tax in Ireland affecting the services sector.

This model indicates that a reduction in the rate of corporation tax in the 1990s stimulated exports and, even allowing for profit repatriations by foreign firms and replacement of lost tax revenue, it resulted in an increase in domestic output. The increase in profitability suggests that some of the increased output involved relocation of profits to Ireland by multinational firms
