 note = {application/pdf, IDP000155_001, This paper investigates Japanese trade by mode of transport, i.e., air transport versus maritime shipping. Some facts about Japanese machinery exports by mode of transport in the 1990s are examined first. Then it will be shown that products of the machinery sector where international fragmentation prevails are more likely to be exported by air.},
