A method of defining relative factor abundance based on ratios of factor prices in autarky: Compared to country B, country A is abundant in factor X relative to factor Y iff w_X^A/w_Y^A < w_X^B/w_Y^B, where w_I^J is the autarky price of factor I in country J, I=X,Y, J=A,B. This is also known as the "Ohlin definition," since it is the one used by Ohlin (1933).
