The Coffeeconomics index is an alternative index to evaluate the Coffee market structure behaviour from a microeconomic and macroeconomic perspective. Hence, the coffee market structure is formed by the interaction of four large players such as coffee producers (small, cooperatives, and large), coffee brokers, coffee sellers (large, medium, and small), and coffee consumers. The main objective is to evaluate the vulnerabilities of the coffee market structure as a whole through the application of the National Coffee Production Function (NCP-Function). Finally, we calculate the NCP-Function to evaluate the risk and vulnerability of the coffee market structure of Guatemala between 1928 and 2018 respectively.
