Explain how economists model how an increase in government expenditure can lead to a greater increase in national income.
Ans. National income is the total amount of wealth that accrues to the permanent residents of a country as a result of the production of goods and services within a country during the course of a year. It is important to measure national income because it shows whether the standard of living in a country is rising or falling and it can be used as a means of comparison between other countries. It is also useful to measure income against past income in the same country to see whether the economy is growing or declining.

Here's what a star student thought of this essay
Quality of writing
Spelling and grammar are absolutely fine, which is obviously a good thing as spelling and grammar may be assessed when being marked. The layout was very good, with paragraphs for each new topic, for instance there was a new paragraph for analysis. Separating work out like this makes your work look clearer and easier to understand. This essay received a full five stars, for answering the question perfectly, with good spelling and a small but good amount of analysis.
Level of analysis
The question is only a describe and explain one, so there was no need to analysis. The level of explanation was very good, and would be a good source to turn to for an explanation of the multiplier effect. Also the author brings in a little bit of analysis in the last paragraph by discussing the impact of inflation on measurements, which although brief, works as a good aside.
Response to question
The author answers the question perfectly. They define all the key terms (National Income) and describe/ explain the multiplier effect, excellently. Good use of diagram to help explain the concept and importantly explains how the diagram relates to the question. Also defining key terms at the start of any essay is greatly recommended, as it shows instantly an understanding of the topic.
