If I explain to you from the table, brother, how much is the overall demand, how much is the estimated employment, this is the overall demand and the overall demand as well as the level of overall demand and employment, that is, even when the level of employment was zero, there was an estimated demand of Rs 240 crore in our economyIt is possible that the level of employment may be zero but the demand in the economy was at that time, people do not die of hunger and as we are talking about 5 lakh employment, the overall demand became 300 crore, 10 lakh employment became 350 crore, the overall demand became 350 crore in crore rupees and this is 15 million, this is in million lakh or 10 lakh, whether we are talking about this, this is 400 croreIn this way, as the aggregate demand is increasing, our employment level is also continuously increasing, that is, if we look at the aggregate demand, then the aggregate demand curve will appear to us like this where this is the aggregate demand and this is your employment level. Now many students will think that why do this in this way and for what reasonWe will do a deep analysis of this also sometime in the next lecture. You will see that there is a limit consumption function, that is, if you divide the aggregate demand, then it depends on two factors. In the theory of consumption and investment, this is our consumption. Children, understand very carefully and this is our investment. When you think about the consumption functionYou would like to know the meaning of consumption function. Consumption depends on income. Consumption is the function of income. As income increases, consumption will also increase but the tendency of consumption to increase will be less than the tendency of increase in income. This is a psychological law of consumption. If we understand a little more about further consumptionSo you will understand its two types of propensity: Marginal propensity to consume. Average propensity to consume. This is called marginal propensity to consume. This is called average propensity to consume. What is the meaning of average propensity to consume? What is the meaning of marginal propensity to consume? If you understand this a little, then you will understand the slope of this curveYou will understand that marginal propensity to consume tells you how much consumption increases if your income increases by one. If you look at this word technically, generally marginal propensity to consume is less than one and greater than zero. What will be the marginal professor area? It will be less than one andWill be more than zero because of King&#8217;s psychological law. What is this psychological law? A person does not spend all his income on consumption, rather he saves some part of it. Saving gives rise to investment, but before understanding this investment, you should know a little more about the average consumption tendencyConsumption propensity tells us what is the mutual relationship between income and consumption, that is, it represents long-term consumption propensity, it represents short-term consumption propensity and if we think about investment, it means that the limit of consumption propensity, if we go deeper into it, MPC is the function of rate of interestAnd income of the marginal propensity to consume will be a function of interest rate and income, whereas the average propensity to consume will depend on the limited income. We gave a small explanation that due to the decreasing trend of aggregate value and marginal propensity to consume, the slope of the average revenue curve becomes like this. Similarly, when you think about investmentIf we discuss completely then we will discuss a little more, students, that&#8217;s all today, if you are interested then you can join our online class, you will understand very well, whatever be your CBSE board, we are starting it in English as well as in Hindi, be it your UP Board or any other boardNCERT books are going on in discussion, it is going to be very fruitful for those children, with that today I complete it, we will meet tomorrow with new topic, thank you student.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Student, today we will discuss a very important topic of 12th standard, whose employment theory is the prestigious employment theory, then there is a very important tool in King&#8217;s employment theory, the tool whose name is Samagra Nirman, today we will discuss a small point, after all, this is Samagraman or Everyday DemandWe will discuss [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":243,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-242","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-toppers"],"_links":{"self":[{"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/posts\/242","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/comments?post=242"}],"version-history":[{"count":1,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/posts\/242\/revisions"}],"predecessor-version":[{"id":244,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/posts\/242\/revisions\/244"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/media\/243"}],"wp:attachment":[{"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/media?parent=242"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/categories?post=242"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/saiwebs.com\/economicstopperslab\/wp-json\/wp\/v2\/tags?post=242"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
