An economy is initially closed to trade and has no government sector, with a marginal propensity to consume ( $M P C$ ) of 0.75. The government then introduces a flat-rate income tax, resulting in a marginal propensity to tax ( $M P T$ ) of 0.10. Simultaneously, the economy opens to international trade, leading to a marginal propensity to import ( $M P M$ ) of 0.15.

Assuming the marginal propensity to save ( $M P S$ ) remains at its original rate out of national income, what is the new value of the national income multiplier?
