The changing economic impacts of the port of New York

This paper investigates the economic effects of maritime trade through the Port of New York on the New York metropolitan region. It decomposes the impacts associated with the trans-shipment of waterborne exports and imports in 1977 and 1987 into those arising from the changing tonnage of trade and those attributable to the changing commodity mix. Input-output analysis is used to calculate the numbers of jobs, personal and business incomes, and output which arise from each effect. Finally, it examines the impacts on specfic industries and occupations in the region.
