World Tourism: An economic analysis

Although interest in international trade is of long standing, economists and policy makers have seldom attempted to link international tourism with trade theory — despite the growing importance of international tourism as a component of international trade. As per Wahab (1975), there is a dearth of scientific books covering the wide range of tourism subjects. In fact, he says “not more than half a dozen books have appeared in the English language in Europe and America on the subject of tourism between 1970–1975”.
