Master Purushottam
मांग के नियम परिभाषा के अंतर्गत बस्तुओं और उनकी मात्रा एवं उनके मूल्य के मध्य के संबध की व्याख्या कि जाती है| बाजार में कोई बस्तु कितनी मात्रा में उपलब्ध है और उसकी कितनी कीमत ली जा रही है यही इस परिभाषा के अंतर्गत व्याख्यायित किया जाता है| बाजार में यदि किसी बस्तु की मात्रा ज्यादा उपलब्ध है तो इसका सीधा सा अर्थ है की उसकी कीमत कम होगी| लेकिन यदि उसकी मात्रा कम है तो जाहिर सी बात है कि उसकी कीमत ज्यादा होगी|लेकिन कुछ नियम ऐसे भी है जोकि इस मांग के नियम की सही परिभाषा नहीं दे पाते हैं|
