Trade Liberalization or Oil Shocks: Which Better Explains Structural Breaks in International Trade Ratios? Academic Article uri icon

abstract

  • Abstract Ben-David and Papell's (1997) tests for structural breaks in trade ratios over the postwar period revealed that trade ratios exhibited structural breaks in their paths and that postbreak trade averages exceeded prebreak averages. They attributed these breaks to trade liberalization measures carried out during this period. We re-evaluate their results and find that for most countries the averages of actual postbreak ratios were below the averages of the extrapolated prebreak ratios and that a large share of the breaks coincided with the 1970s oil shocks. This would suggest that the oil shocks rather than trade liberalization may account for the breaks.
