Abstract
A study was undertaken to analyze the trend, seasonal and spatial variations in retail egg prices in Tamil Nadu. In Tamil Nadu,
four major consumption centers were selected by simple random sampling method. The data on monthly retail egg prices for the period
from April 1990 to March 2015 were collected from various secondary sources. The retail egg price trend equation fitted for selected
four major consumption centers of Tamil Nadu revealed that the egg price had increased constantly by 0.008 paise per egg every month.
The intercept of trend equations fitted for four districts of Tamil Nadu were found to be around 0.491 (0.483 to 0.510). The monthly egg
price index was observed to be the minimum during the month of April and started increasing to reach peak during the month of June.
Further, it started decreasing and reached lower value during the months of September and October. The seasonal retail egg price index
was found to be the highest during the month of June and the lowest during the month of April. The spatial price relationship between
four major consumption centers of Tamil Nadu namely Chennai, Madurai, Trichy and Coimbatore is perfectly positive because the
correlation coefficients were found to be around 0.987 (0.986 to 0.990). This indicates that four major consumption centers of Tamil
Nadu namely Chennai, Madurai, Trichy and Coimbatore were highly correlated for retail egg price.
