The law of diminishing marginal utility is universal in character. It is based on the common consumer behaviour that utility derived diminishes with the reduction in the intensity of a want.<\/p>\n\n\n\n<p><strong>Statement of the Law of DMU:<\/strong><br>According to Prof. Alfred Marshall, \u201cOther things remaining constant, the additional benefit which a person derives from a given increase in his stock of a thing, diminishes with every increase in the stock that he already has.\u201d<\/p>\n\n\n\n<p>In other words, a marginal utility that any consumer derives from successive units of a particular commodity goes on diminishing as his or her total consumption of that commodity increases. In short, the more of a thing you have, the less you want to have more of it.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/microeconomic-definition\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/microeconomic-definition\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Microeconomic Definition | Historical Review of Microeconomics<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/scope-of-microeconomics\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/scope-of-microeconomics\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Scope Or Nature of Microeconomics<\/strong><\/a><\/li>\n\n\n\n<li><strong><a href=\"https:\/\/scholarsclasses.com\/blog\/exceptions-to-the-law-of-diminishing-marginal-utility\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/exceptions-to-the-law-of-diminishing-marginal-utility\/\" target=\"_blank\" rel=\"noreferrer noopener\">Exceptions of Law of Diminishing Marginal Utility<\/a><\/strong><\/li>\n\n\n\n<li><strong><a href=\"https:\/\/scholarsclasses.com\/blog\/criticism-of-law-of-diminishing-marginal-utility\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/criticism-of-law-of-diminishing-marginal-utility\/\" target=\"_blank\" rel=\"noreferrer noopener\">Criticism of Law of Diminishing Marginal Utility<\/a><\/strong><\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" data-src=\"https:\/\/scholarsclasses.com\/blog\/wp-content\/uploads\/2021\/06\/Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU-1024x576.png\" alt=\"Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU\" class=\"wp-image-3267 lazyload\" title=\"\" data-srcset=\"https:\/\/scholarsclasses.com\/blog\/wp-content\/uploads\/2021\/06\/Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU-1024x576.png 1024w, https:\/\/scholarsclasses.com\/blog\/wp-content\/uploads\/2021\/06\/Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU-300x169.png 300w, https:\/\/scholarsclasses.com\/blog\/wp-content\/uploads\/2021\/06\/Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU-768x432.png 768w, https:\/\/scholarsclasses.com\/blog\/wp-content\/uploads\/2021\/06\/Assumptions-of-Law-of-Diminishin-Marginal-Utility-DMU.png 1280w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/576;\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center has-cyan-bluish-gray-background-color has-background\">Assumptions of the Law of Diminishing Marginal Utility<\/h4>\n\n\n\n<p>The following are the <a href=\"https:\/\/youtu.be\/107GPNlzKV8\" data-type=\"URL\" data-id=\"https:\/\/youtu.be\/107GPNlzKV8\" target=\"_blank\" rel=\"noreferrer noopener\">assumptions<\/a> of the law of diminishing marginal utility:<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">1) Rationality<\/span><\/strong>:<\/p>\n\n\n\n<p>The consumer is assumed to be rational. It means that his behavior is normal and he tries to maximize his satisfaction.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">2)Cardinal measurement<\/span><\/strong>:<\/p>\n\n\n\n<p>The law assumes that utility can be cardinally or numerically measured. Hence, mathematical operations are easily possible to know and compare the utility derived from each unit of a commodity.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">3) Homogeneity:<\/span><\/strong><\/p>\n\n\n\n<p>All units of a commodity consumed are exactly homogeneous or identical in size, shape, colour, taste, etc.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">4) Continuity:<\/span><\/strong><\/p>\n\n\n\n<p>All units of a commodity are consumed in quick succession without any lapse of time.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">5) Reasonability:<\/span><\/strong><\/p>\n\n\n\n<p>All the units of a commodity consumed are of reasonable size. They are neither too big nor too small.<\/p>\n\n\n\n<p><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\"><strong>6) Constancy:<\/strong><\/mark><\/p>\n\n\n\n<p>All the related factors like income, tastes, habits, choices, likes, and dislikes of a consumer should remain constant. The marginal utility of money is also assumed to be constant.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">7) Divisibility:<\/span><\/strong><\/p>\n\n\n\n<p>The law assumes that the commodity consumed by the consumer is divisible so that it can be acquired in small quantities.<\/p>\n\n\n\n<p><strong><span class=\"has-inline-color has-vivid-purple-color\">8) Single want:<\/span><\/strong><\/p>\n\n\n\n<p>A given commodity can satisfy a single want of a person. The law assumes an experience of a single want that is completely satiable at a given point of time.<\/p>\n\n\n\n<p><strong>Other Related Topics:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/importance-of-law-of-diminishing-marginal-utility\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/importance-of-law-of-diminishing-marginal-utility\/\" target=\"_blank\" rel=\"noreferrer noopener\">Importance of Law of Diminishing Marginal Utility<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/utility-in-economics-meaning-concepts\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/utility-in-economics-meaning-concepts\/\" target=\"_blank\" rel=\"noreferrer noopener\">Utility in Economics ( Concepts of Utility )<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/features-of-utility\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/features-of-utility\/\" target=\"_blank\" rel=\"noreferrer noopener\">Features of Utility<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scholarsclasses.com\/blog\/types-of-utility\/\" data-type=\"URL\" data-id=\"https:\/\/scholarsclasses.com\/blog\/types-of-utility\/\" target=\"_blank\" rel=\"noreferrer noopener\">Types of Utility<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>&#46;&#46;&#46;<\/p>\n","protected":false},"author":1,"featured_media":3267,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[1706],"class_list":["post-3254","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-misc","tag-assumptions-of-law-of-diminishing-marginal-utility-in-points"],"_links":{"self":[{"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/posts\/3254","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/comments?post=3254"}],"version-history":[{"count":9,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/posts\/3254\/revisions"}],"predecessor-version":[{"id":39033,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/posts\/3254\/revisions\/39033"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/media\/3267"}],"wp:attachment":[{"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/media?parent=3254"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/categories?post=3254"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scholarsclasses.com\/blog\/wp-json\/wp\/v2\/tags?post=3254"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
