In many textbooks - like P. Krugmann, International Economics (2000), page 163 - a simple
diagram is used to illustrate the effects of international factor mobility between country
A and country B.  The horizontal axis represents the total stock of the factor in
question. A schedule representing the decreasing marginal product of the factor for
country A is drawn from the right axis, and a marginal product schedule for country B is
drawn from the left axis.
 
The diagram can also be found in the 1930's as an illustration of the marginal principle
of dividing a given amount of a factor of production between to types of production.  From
where does this diagram originate? Who was the first to introduce it in the marginal
productivity theory and in the theory of nternational economics?
