“ Even in recent times, the empirical evidence does not support the claim that trade liberalization or incentive neutrality leads to faster growth. It is true that higher manufacturing growth rates have been typically associated with higher export growth rates (mostly in countries where export and import shares to GDP grew), but there is no statistical relation between either of these growth rates or degree of trade restrictions. Rather, almost all of successful export-oriented growth has come with selective trade and industrialization policies. In this regard, stable exchange rates and national price levels seem to be considerably more important than import policy in producing successful export-oriented growth ”
