Resumen:
Engel curves remain as robust tools for consumer behavior testing across the World. Linear (or almost linear) relationship between income and food share expenditure has been found in different academic works. We extend previous works by analyzing compositional data and by extending analysis into food components. Cultural and geographical patterns affect diet composition so careful control variables design is required for error minimizing. Compositional data analysis (CODA) remains as the ideal technique for analyzing this particular constrained data. Aitchison log-ratio transformations are applied to panel data estimation.
