The objective of this study is to investigate the use of national accounts data in measuring the impact of increased investments in the Blue Economy, which is all economic activities originating from the ocean and its natural resources. The outputs from these activities may be demanded for final consumption, or as inputs into other productive processes (Caribbean Development Bank, United Nations Development Fund, 2018). The measurement of a country’s national output is tied to its national accounting framework, which measures the contribution of individual industries to domestic economic activity. The researchers, therefore, propose to test the adaptability of the current national accounting systems to respond to changes in the outputs of Blue Economy industries.
