Definition

An input-output table (I-O table) is a systematic arrangement of data that showcases the transactions between different industries within an economy. Specifically, it displays the amount of output from one industry that is utilized as input by other industries. This inter-industry flow of goods and services provides crucial insights into the structural relationships within an economy, allowing for the analysis of how industries are interconnected and how changes in one sector can influence others.

Examples

  1. Manufacturing and Transportation: An I-O table might show how much raw material from the manufacturing industry is supplied to the transportation industry.
  2. Agriculture and Food Processing: It could detail the quantity of agricultural produce like wheat used by the food processing industry to manufacture bread and other products.
  3. Energy Sector: It may illustrate how much electricity generated by the energy sector is consumed by various other industries such as manufacturing, residential, and services.

Frequently Asked Questions

What is the purpose of an input-output table?

The main purpose of an input-output table is to provide a detailed account of how different industries interact within an economy. It helps in tracing the flow of goods and services and can be used for economic planning and analysis.

How frequently are input-output tables updated?

Input-output tables are typically updated on an annual basis, although this can vary by country or economic institution. Some regions may update them less frequently, depending on the availability of data and resources.

Can input-output tables be used for forecasting?

Yes, input-output tables are used for forecasting economic conditions. By inputting assumptions about future economic conditions, these tables can generate predictions about aggregate economic activity and trends.

Are input-output tables applicable globally?

Yes, input-output tables are used globally, across various economies, to understand and analyze industrial relationships and economic activity. The specifics might differ due to variations in data availability and industry classification.

How are input-output tables constructed?

I-O tables are constructed using statistical data collected from surveys and industry reports. The data is typically organized into a matrix format that shows the expenditure of each industry on inputs from every other industry within the economy.

  • Economic Model: A simplified framework designed to illustrate complex economic processes.
  • Aggregate Economic Activity: The total economic activity within an economy, combining various sectors.
  • Supply Chain: The network of suppliers, manufacturers, and distributors involved in producing and delivering a product.
  • Gross Domestic Product (GDP): The total value of goods produced and services provided in a country during one year.
  • Sectoral Analysis: The examination of individual sectors within an economy to understand their structure and performance.
