Public Investment and Income Taxation: Redistribution vs. Productive Performance

This paper deals with government investment in a static two-type self-selection model of optimum income taxation. It is shown that the second-best investment rule is consistent with efficient production, provided that public investment has no influence on relative factor prices. Otherwise, however, redistributive income taxation implies that optimal investment expenditures exceed (or fall below) the efficient level as long as they raise (or decrease) the wage rate of the unskilled individuals relative to the wage rate of the skilled individuals.
