Consumption and savings relationship test

consumption and savings relationship test

The relationship between income, savings, and consumption is directly related to the price level in the economy. Your research has shown that for every. To conduct this analysis, we have applied tests to verify if the time series. The relation between consumption, income and GDP is stronger for low . Moreover, consumption is concurrent with savings, which are a source for. The first concerns the relationship between consumption and financial .. and the lagged saving rate (along with the p-values from tests of the.

Let's say if there's some above and beyond the base level, they're going to spend 0. Actually, to be a little bit more particular, I'll write not just income, I'll write disposable income.

I'll want to do that in a different color. I make the distinction, just to clarify our model, between income and disposable income because all of the aggregate income in an economy does not end up in consumers' pockets. Just for a simplification, you might say, "Yeah, some of it ends up in firms' pockets," but the firms, at the end of the day, are owned by individuals, so it can end up in individuals' or consumers' pockets.

But some of it goes off to the government. When you think about income, and if you spend any time looking at your pay stub this will become familiar to you, you have your income but you don't end up with all of that in your checking account or your pocket or your savings account. A good fraction of that is taken out for taxes.

What you have left over when you subtract taxes out of income, that is your disposable income. That's why I write this here because that's actually a more reasonable thing to say.

They obviously can't spend a fraction of stuff that they don't have, the stuff that's taken out for taxes. Just to visualize this, we can draw it. This will be a line. This might ring a bell from your early algebra days. Just the variables are different. Instead of a y, we have a c, but that's still the dependent variable. It's a function of disposable income. In algebra you'll often call this the independent variable. The most typical variable is x.

It's really the same idea over here. Let me draw this a little bit neater. We can graph this, what's essentially going to be a line.

It doesn't have to be a line. We just constructed a consumption function that happens to be a line. This is consumption right over here in the vertical axis.

Consumption function basics

That could be in billions of dollars or clamshells or whatever else. Then right over here we have disposable income. If there is zero disposable income, maybe I'll draw a little table over here. This is I'll call it disposable income and this is consumption. If there's zero disposable income, then this whole term right over here is 0. Then you have billion dollars, or whatever our units are, of base consumption.

This would correspond to this point right over here. In the horizontal axis you don't move at all because this is 0. Vertical axis is So you have Let's say disposable income is 1, whatever our units are.

So this is Let's say this is 1, billion clamshells. This could be in billions of clamshells. We use gross national income GNI per capita as a proxy to represent income and household final consumption as a proxy to represent consumption.

The long run relations are estimated by cointegration model. The results show that there are positive and significant long run relationships between GNI and consumptions for Bulgaria and Russia. It states that the consumption depend on income; a rise in income increases the consumption.

In Bulgaria, the income-consumption relationship is more pronounced than in Russia. Consumption; Bulgaria, Russia, income, cointegration analysis 1. Introduction Households increase their utility by consuming the produced goods and services.

They increase their well-being by this major component of the aggregate demand.

For this reason the possible determinants of the aggregate consumption function have been analyzed intensively in the economic literature.

The purpose of this study is to estimate income-consumption relationship for the Bulgaria and Russia using time series data from the World Bank group. The broad hypothesis being tested is that consumption is closely related to the level of current income.

The hypothesis rests on idea that consumption is made possible on the amount of money available for spending. Literature review Consumption accounts a significant proportion of national income, hence it is a main factor to promote economic growth. Hence for this reason, exploring the relationship between consumption and income, generally labeled as consumption function has played main role in economic theory since Keynes introduced Absolute Income Hypothesis AIH from The General Theory.

It expresses the functional income-consumption relation and all its determinants. It is a single mathematical function used to express consumption expenditure, it can be written as: The simple function is written as the linear function: Keynesian theorywhat is known as the Absolute Income Hypothesis AIHand postulates that the consumption level of a household only depends on its absolute level current level of income and ignores the potential future income.

The hypothesis also states that as income rises, consumption will also rise but not necessarily at the same rate. That means income-consumption relationship is not proportional. Unlike the Keynesian consumption theory is entirely based on the current income of the individuals while the concept of LCH assumes that all individuals consume a constant percentage of present value of their life income.

The life cycle model also assumes that all individuals save while they work in order to finance consumption after they retire. The key assumption is that all individuals choose to maintain stable lifestyles.

That means they keep their consumption levels approximately the same in every period instead of saving in one period to spend furiously in the next period. The theory makes three assumptions as follow: Interest rate is stable throughout the lift time of the consumer.

The consumer does not inherit any assets. The life cycle model can be expressed as: In its simple form, the hypothesis argues that consumption is not by current income but depends on expected average income and transitory income. The key conclusion of this theory is that transitory, short-term changes in income have little effect on consumer spending behavior.

Friedman uses permanent income as the determinant of income.
