How do differences in the national income of different countries affect their economic development ?

National is the total number of goods and services produced in a country in a given year.

Explanation:

National Income is simply a country's wealth and it goes a long way in shaping the economic development of a country. From, the definition of national income, we should know that every country national income( i.e  the net amount of income of the citizens by production in a year) will differ hence, the difference in their economic  development.

National Incomecan be classified in to two namely:

GDP: Gross domestic product is the aggregate value of goods and services produced in a country. it is used to measure a country 's economic growth.

GNP: Gross National Product on the other hand is the estimated value of the final goods and services produced by a country during a specific period of time (usually a year),before allowance is made for the depreciation or consumption of capital used in the process of production.

IF country A GDP is 52,000 while that of Country B is 45,000. We can say country A is economically developed than country B. i.e Country A is experiencing more positive  growth than country B.

This explains a vivid answer to the above question as all country can not grow at the same rate since their national income differs. the higher the national income of a country, the better  it is from  others.

explanation: doctrine of respondeat superior is a legal doctrine that is commonly used in tort. this principle makes an employer or principal legally responsible for the wrongful acts done by an employee or agent, if such acts occur within the scope of the employment or agency.
