It is shown that deindustrialization is explained primarily by developments that are internal to the advanced economies. These include the combined effects on manufacturing employment of a relatively faster growth of productivity in manufacturing, the associated relative price changes, and shifts in the structure of demand between manufacturers and services. North-south trade explains less than one-fifth of deindustrialization in the advanced economies. Moreover, the contribution of north-south trade to deindustrialization has been mainly through its effects in stimulating labor productivity in northern manufacturing; it has had little enduring effect on the total volume of manufacturing output in the advanced economies.
