		| Within a tax competition framework, this note points out that the tax principle of Formula Apportionment may render corporate income taxation of multinational enterprises efficient even if a sales apportionment
factor is not available. This is shown for constant returns to scale production functions with substitution elasticity greater than or equal to one. In the special case of a Cobb-Douglas production function, efficiency is attained either if the formula uses only payroll or if the formula weights on production inputs equal these inputs' production elasticities. |
