Does a smaller domestic economy bear a larger corporate tax burden?
Core argument: The model sets the domestic economy at 30% of world output, with domestic residents owning 30% of world output; the corporate tax burden is neither exported nor imported, given equal initial wealth endowments and no tariff-like effects.
The analysis of international corporate income tax burdens relies on key assumptions, such as perfect capital mobility and equal output capital intensities in tradable sectors, which are later relaxed. The model assumes two identical economies differing only in size, with production divided into five sectors, three of which are corporate. Labor is perfectly mobile within countries but not internationally, while capital is fixed globally yet mobile between countries. The domestic economy accounts for 30% of world output, and domestic residents own 30% of world output. The tax burden is not exported or imported due to equal initial wealth endowments and no tariff-like effects. The excess burden is largest when the domestic economy is smallest, as the corporate tax inefficiently reallocates capital away from the domestic sector.
