Income Effect vs. Substitution Effect: What's the Difference?

The consumption function is a relationship between current disposable income and current consumption. It is intended as a simple description of household behavior that captures the idea of consumption smoothing. We typically suppose the consumption function is upward-sloping but has a slope less than one. So as disposable income increases, consumption also increases but not as much. More specifically, we frequently assume that consumption is related to disposable income through the following relationship:.

The relationship between income and expenditure is often called a consumption schedule. It is used to describe economic trends in the household sector. When there is more money or anticipation of income, more goods are purchased by consumers. Meaning money is spent on expenditures, at times, even if there isn't enough income to cover them. This is a common economic principal used to describe spending trends for national and world economies. A business should consider the relationship between consumption and savings to extract data on buyer trends within its own industry. The difference between income and consumption is used to define the consumption schedule.

This paper analyses the level of inequality in Spain and how it evolved over the course of the past crisis and the early stages of the current recovery. To this end, it first introduces the various dimensions of wage, income, consumption and wealth inequality, and studies how they have developed. The analysis shows less wage dispersion in Spain than in other comparable economies, even after the crisis years, while the surge in unemployment during the period resulted in a high level of inequality in per capita income. The level of inequality in Spain is more moderate when total gross household income is analysed, decreasing during the crisis as a result of pensions developing more favourably than other sources of income, in conjunction with young people delaying setting up home. Inequality in per capita consumption rose during the crisis, particularly as a result of a decrease in expenditure on consumer durables by low-income households. Wealth inequality exceeds income inequality and increased during the downturn as a result of financial assets outperforming real assets. The way inequality has evolved during the early stages of the current economic recovery shows that falling unemployment has enabled a reduction in wage income inequality, as well as in per capita income inequality, albeit to a lesser extent.

This study examined the household and government consumption with income separately both in short and long run. The data is collected from the WDI from to of spain. In contrast ,the expenditures of government and consumption is more than that of its income in long run and vice versa. The reason for the more expenditures in long run is due to the debt financing.

1 million, the consumption increases by Rs. million. The potential of consumption was higher in higher income households. Findings are in line with the Keynes economic theory [1], which suggests that the income variable has positive effect on household consumption.

Income, consumption and wealth inequality in Spain

Propensity to consume is also called consumption function. In the Keynesian theory, we are concerned not with the consumption of an individual consumer but with the sum total of consumption spending by all the individuals. Aggregate consumption depends on consumption function or propensity to consume.

The permanent income hypothesis PIH is an economic theory attempting to describe how agents spread consumption over their lifetimes. First developed by Milton Friedman , [1] it supposes that a person's consumption at a point in time is determined not just by their current income but also by their expected income in future years—their "permanent income". In its simplest form, the hypothesis states that changes in permanent income, rather than changes in temporary income, are what drive the changes in a consumer 's consumption patterns. Its predictions of consumption smoothing , where people spread out transitory changes in income over time, depart from the traditional Keynesian emphasis on a higher marginal propensity to consume out of current income. It has had a profound effect on the study of consumer behavior, and provides an explanation for some of the failures of Keynesian demand management techniques. In the permanent income hypothesis model, the key determinant of consumption is an individual's lifetime income, not his current income. Permanent income is defined as expected long-term average income.

In contrast to most recent studies of economic inequality, which separately examine income, consumption, and wealth inequality, this paper, using Panel Study of Income Dynamics PSID data from through , considers the relationship between the three factors to determine whether the effects of changes in income on consumption are more pronounced at higher or lower levels of wealth. The authors—the first to use the PSID to estimate the marginal propensity to consume MPC by wealth—find that the MPC is indeed lower at higher wealth quintiles, suggesting that lower-wealth households respond more to changes in income than do higher-wealth households. They also find that the overall MPC lies at the low end of the range examined in other research, but this discrepancy is to be expected, the authors conclude, because the PSID documents two-year changes in income and consumption, while other studies use changes over shorter periods of time.

In this direction, Keynes (;, p. ) suggested that individuals tend to increase consumption as their income increases, but to a lesser extent. This fundamental psychological law states that as the level of income increases, the difference between income and consumption increases as well.


Consumption function , in economics , the relationship between consumer spending and the various factors determining it. At the household or family level, these factors may include income, wealth, expectations about the level and riskiness of future income or wealth, interest rates, age, education, and family size. The characteristics of consumption functions are important for many questions in both macroeconomics and microeconomics. In macroeconomic models the consumption function tracks total aggregate consumption expenditures; for simplicity it is assumed to depend on a basic subset of the factors economists believe are important at the household level. Analysis of consumption expenditure is important for understanding short-term business cycle fluctuations and for examining long-run issues such as the level of interest rates and the size of the capital stock the amount of buildings, machinery, and other reproducible assets useful in producing goods and services. In principle, the consumption function provides answers to both short-run and long-run questions.

Permanent income hypothesis

This study analyses the relationship between energy consumption and economic growth for countries during the period of , classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyze whether the causal relationship differs between different income groups of countries. The results of the study indicate that the causal relationship between energy use and economic growth differs depending on which income group country belongs to.
