Consumption function - Wikipedia
This is an implication of service to God. Given this relationship between wealth and income, consumption is defined The maximization of success by the consumer is subject to income constraint determined by the level of disposable income. consumption treadmill, but through deeper, more meaningful relationships with We might choose to have less disposable income, and spend more time with. In economics, the consumption function describes a relationship between consumption and disposable income. .. In Judaism, the Sabbath economy and the lessons of the manna brought by God during the Hebrew crossing of the desert.
Now we come to a textbook chestnut: Or we lower taxes and lower government purchases by the same amount.

What is the net effect on the economy? You already have a sense of the answer, from our comparison of the effects of similar changes in G and T above. Because a change in G affects AD fully, while a change in T affects AD only in slightly diminished form by changing C first through the MPCchanging spending is just a little more powerful than changing taxes.
And in fact, you already know enough to tell exactly how much change in Y will be provoked by a matched change in G and T. And by doing that: And in fact, in this simple model the balanced budget multiplier is always exactly 1.
If algebra makes you happy, you can get this result by adding up the two abstract formulas: When the economy is booming and inflationary pressures start to grow in the economy, the Government can decrease G and increase T.
If the budget is normally more or less in balance, then this means that the government runs deficits in recessions, and surpluses in booms. This should stabilize the level of aggregate expenditure and income in an economy.
When the government does this, it is called counter-cyclical policy. Essentially the government is trying to damp down swings in Y. If these swings in Y are part of a normal "business cycle" in which periods of intense capital investment alternate with periods in which firms buy relatively few new capital goods, then it's especially easy to see the rationale for counter-cyclical G: If firms' intended investment Ip falls, that's a component of AD and Y will tend to fall.
In that case, in theory, G can be increased to make up for the fall in Ip.

In real life, this is hard because it may take a while to actually figure out that Ip is dropping, and the political process of approving changes in G or T may drag on for long enough that by the time fiscal policy is actually changed, Ip has risen again.
In this case your intended counter-cyclical policy might actually end up being a pro-cyclical policy, amplifying rather than damping the changes in Ip. Counter-cyclical policy would also lower G when Ip rises, to reduce booms.Investment and consumption - GDP: Measuring national income - Macroeconomics - Khan Academy
You might wonder why anyone would want to do this - aren't booms good? The most often-heard arguments are a that a boom sets up conditions for a painful crash by encouraging over-investment too much Ip, so that it collapses once firms realize they have bought too many machines and b that overly-rapid growth provokes rapid inflation. But in a more sophisticated model, transfer payments and taxes in particular will change as Y changes.
If tax revenues are a percentage of income, then as Y rises taxes will rise by themselves. If transfers like unemployment compensation rise when people lose their jobs and fall when employment rises, then when Y rises transfers fall, and when Y falls transfers rise.
So since net taxes T represent total taxes minus transfer payments, it follows that T will rise when Y rises and fall when Y falls. Note that this amounts to a counter-cyclical policy as described in the previous section, but that it's automatic - it requires no extra decision by government to do this.
This kind of countercyclical policy is also pretty rapid. Another way of saying the same thing is that it sells securities IOUs. But suppose the government already owes money from previous deficits. Then this year's deficit adds to the total debt of the government.
So the federal debt is the total amount owed by the federal government, while the deficit os the amount this debt rises in a single year. In other words the debt is the cumulative total of all past deficits.
Some of this debate has been interesting, and reasonable people can take very different positions on taxing, spending, and deficits. But unfortunately a lot of the discussion has been based on the fallacy that national debt is just like personal debt. Personal debt has to be paid off by a certain point: I might take out loans to go to college, but I won't be able to continue borrowing forever lenders know I have a finite earning lifeand at some point I have to pay it all back.
Additionally, because it has the power to tax nobody will worry about its ability to pay back in the future. So government can keep "rolling over" its borrowing: Of course it still has to pay interest, but the "principal" - the amount of the original borrowing - never has to be repaid.
This does not mean that we have discovered some kind of magic beans. Government borrowing does have consequences and they can be, arguably, bad. But to think about those consequences you have to think in real terms: Let's tick off some not all of the reasons that deficits might harm or help. Deficits might be useful for: Low-income areas may actually see more in expenditures than in actual income at different times.
The difference between income and consumption is how much is spent and left over as savings at the end of the month. There are many factors that determine why consumers choose to spend more on goods not required for day-to-day living expenses. These include stock market trends, tax laws, and even consumer optimism.
Economic experts look at historical data to predict future trends based on new market conditions. The Effect of Consumer Confidence Consumers won't spend money unless they are confident in their personal economic situation and strength. This means consumers feel good about having and keeping a job with the potential of promotion. Pay increases, stock portfolio rises and tax cuts can put more money in each person's pocket.
As these conditions merge, consumer confidence increases. Consumer confidence is the trust a buyer has that he can afford a purchase either today or in the near future. For example, consumer confidence is shown by homebuyer trends. This is a major purchase that takes decades to pay off.
Relationship between Disposable Income and Consumption
A buyer must feel good about the economy, as well as feeling secure about his personal financial situation to take on such a major purchase. Establishing Business Inventory Practices Another factor that affects consumer confidence in inventory. Supply and demand have a strong effect on whether buyers feel there is a need to purchase now. Going back to the house purchasing example, if there are not a lot of homes for sale but interest rates are low, supply is down but demand may increase.
This could lead to higher buying desires among consumers trying to get in while they can for the best deal possible.
