In the post Covid days the budget constratint has its niche to identify the inflationary rate in case of buying the inventory in case of Economic quantity demanded with the revised assumptions. Hence,its most pivotal for the downward slope in the production curve of the industrial phenomenon. Hence,all the subsidirat affecting the quantity demanded will be the hardest portion which needs the utmost discussion often. Thus marginal replacement of goods may be a hugh value in case of diminishing of marginal returns in case of managers.

One point I wanna make to the "food/shelter" case, if most people living below the poverty line do prefer shelter, it is better to not give them cash but other life essentials. Because if everybody spend more money on shelter, they would just drive up the low-end housing price. Because they are the target group of that market anyways, so if all of them are capable of/willing to pay more money, the competition'd make price goes up and money goes to the landlords.

In lesson 2 professor Gruber mentioned addictive behaviour, like smoking, can change your utility function over time. So I think an idealized perfectly rational agent should take this into account, but in practice doesn't look so simple. In these cases, are economists more amenable to some form of paternalism?
@pickyraccoon
@pickyraccoon 2 года назад
Look for Richard Thaler and Cass Sustein. They coined the term "libertarian paternalism" and it's well used in behavioral economics as a whole. 😊
@suindude8149
@suindude8149 3 месяца назад
In case of the optimization of life's own temporal value,the most optimistic way in the risk dissoluted scenario of the macroeconomic behaviour,it's really the inverse utility of paternalism if we don't accept the indifference to the smoking habit,the utility of other habits like overeating or any kind of portion that affects the micro temporality creates a long difference in the human behaviour. In that context one indifference of temporality comes in my way of thought as the technical improvement in the world of cheap and sustainable technical imposition to increase the micro utility to support the entire product mix would be a great strategy concentric in case of the product generation.Hence a complete inversion of inverted utility to the actual utility function hence,the same is here the increase in marginal utility by relinquishing the smoking habit would be far more better replacement of everything having high utility function including a saviour in the irrational behaviour to the human being the high penetratiin of sustainability.

@nataliabishop5482 Год назад
What if I found a place that sold $5 cookies and not $6 so I could buy more for less? How would this effect the equation after the fact? I see how it’d stay if the $5 cookie was the original price but let’s say it’s not..? That or like.. what if there’s a sale?
@bhavikaborawat8323
@bhavikaborawat8323 Год назад
Shouldn't the decrease in budget constraint (imposed by parents) lead the students to opt the cookies more because they are cheaper and hence the slope of curve to change (increase -vely) thus creating a fractional MRT?
@7amseel
@7amseel Год назад
MRT is the ratio of market prices of two goods. It is independent of your income or budget constraints. The decrease in income will in some combination lower both the amount of cookies and the amount of pizza. However, the exact combination by which pizza slices and cookies get lowered depend upon your utility function which ultimately makes your indifference curve.
@dennis7928
@dennis7928 Год назад
QUESTION: minute 28.48 > " you're willing to give up 2.5 p for 1 c" is incorrect right? Looking at the graph (minute 29.18) the indifference curve looks like that you're willing to give up 2.5 p for 2 c as the interval on the x axis is not 1 but 2. Can someone either tell me that I am right, but more likely explain why I am wrong?
@7amseel
@7amseel Год назад
"You're willing to give up 2.5 P for 1 C" is correct. If you look at the graph (29:18) more closely, you will see that at point A, the value at x axis is 2, but also the value of y axis is 5. So basically, you are willing to give up 5 pizzas for 2 cookies which is same us giving up 2.5 pizzas for 1 cookie.

@@user-ze1tc1ur9p The derivative of a function (ax)^n is a*n*(ax)^(n-1) where a is a constant. The square root of PC is equivalent to saying (PC)^(1/2) or (PC)^0.5, so if you're deriving with respect to P, P is your x, C is a, and 0.5 is n, so the derivative would be C*0.5*(PC)^(0.5-1) or 0.5*C*(PC)^(-0.5). x^-n is equivalent to 1/(x^n), a negative power just means you move it to the denominator, so you get 0.5*C/(PC)^0.5, and again, x^0.5 is the same as square root of x, so finally you're left with 0.5*C/squareroot(PC). If you do it with respect to C, C is your x instead, you get 0.5*P/squareroot(PC). dU/dP means derivative of U w/ respect to P, dU/dC means derivative of U w/ respect to C.

he is saying that the budget changes (since your disposable income decreases) but the proportion of trade-off between two products remains (since the price of each type remains and the value of each type for you is the same. i.e. the marginal substitution for you is the same). you see the parallel shift of the budget lines but the slope remains.

@yellowusbrickus4821
@yellowusbrickus4821 2 года назад
Probably something to do with structural inequality issues, for example an insurance firm may offer insurance to rich people, R or poor people, P. When P takes out insurance on their cheaper car, the risk of it breaking down are higher and therefore their insurance costs will be higher as a proportion of their income. This could take away P's ability to increase their wealth because the insurance costs eventually wear away their initial endowment. If the group used their money to buy cars to double their wages, they would not be able to afford good cars and thus they would be subject to high insurance costs, leading them back to a point of not being able to afford insurance or a car. This example is obviously not what happened but in built mechanisms can lead to greater wealth inequality over the longer term.

The derivative of a function (ax)^n is a*n*(ax)^(n-1) where a is a constant. The square root of PC is equivalent to saying (PC)^(1/2) or (PC)^0.5, so if you're deriving with respect to P, P is your x, C is a, and 0.5 is n, so the derivative would be C*0.5*(PC)^(0.5-1) or 0.5*C*(PC)^(-0.5). x^-n is equivalent to 1/(x^n), a negative power just means you move it to the denominator, so you get 0.5*C/(PC)^0.5, and again, x^0.5 is the same as square root of x, so finally you're left with 0.5*C/squareroot(PC). If you do it with respect to C, C is your x instead, you get 0.5*P/squareroot(PC). dU/dP means derivative of U w/ respect to P, dU/dC means derivative of U w/ respect to C.

We are forcing them on Food Stamps, because Someone who is below poverty line will use Cash for other purposes.

Move in with someone and give them your food stamps for shelter, go to the food bank for food.
