Assume a country produces only wine and guns. Both wine and gun production use land and labor as their only inputs . W ine production is relatively land-intensive while gun production is relatively labor-intensive . According to the Rybczynski theorem, a s ignificant rise in immigration is most likely to lead to : a. an increase in the production of both wine and guns. b. an increase in wine production by a greater proportion than the increase in the size of the labor force due to immigration . c. an increase in the production of guns by a greater proportion than the increase in the size of the labor force due to immigration. d. an increase in wine production by a greater proportion than the increase in the production of guns .
