the Heckscher-Ohlin model, if Japan has less land per worker, and Australia has more land per worker, then if trade were to open up between these two countries,

the real income of labor in Japan would fall.
the real income of landowners in Japan would rise.
Japan has a comparative advantage in production of manufactured goods and Australia has a comparative advantage in food production, then starting trade between these two countries will
lead to perfect specialization with Japan alone producing manufacturing output. create a world relative price of food that is lower than that of Australia.
