The international competitiveness of brazil nuts: "r" software package for analysis of product dynamics

Objective of the study: to develop a package for analysis in language in the "R" environment, proposing its use in studies of competitiveness and dynamics of forest products, testing it in the Brazil nut market in the period between 1998 and 2017. Methodology/approach: Country trade data were collected, available in the Un Comtrade and FAS/USDA databases. Growth rates, concentration indices - CRK, Market Share (MS) were calculated, and econometric models were adjusted among the main exporters of the product: Brazil, Bolivia and Peru. Five functions were created within the proposed package: 3-line graph, 4-line graph, Concentration_Ratio, and Growth Rate, with the package named MKTDATA, for reference purposes within the "R" community. for measuring competitiveness and dynamics. Results: it was concluded that in the adjustment of the econometric models, significant relationships were observed on market share and price. Bolivia proved to be more competitive MS for the US market, in terms of price changes, while price changes were more inconsistent for Peru. In the case of Brazil, the occurrence of periods of greater and lesser stability in the same item was observed. Theoretical/methodological contributions: methodological contributions were essential in this work, with the exploration of the potentialities of "R" processing. Corporate and social contributions: the use of "R" proved to be robust and versatile in data processing, providing refined explorations of statistics.
