Supply and Use and Input-Output Tables for Ireland 2022

The Input-Output framework of the European System of Accounts (ESA 2010) consists of Supply and Use Tables (SUTs) and Symmetric Input-Output Tables (IOTs). While the SUTs are constructed directly from survey and other administrative data sources, the IOTs are modelled from the preceding SUTs.

Use Table at Basic Prices

To produce the IOTs the Use Table is first calculated at basic prices. This is the price received by the producer for a good or service produced, minus any tax payable as a consequence of its production, plus any subsidy received as a consequence of its production, minus any trade margins made on the product.

Once the Use Table at basic prices is calculated, we disaggregate it into domestic inputs (uses) and imported inputs. In total, there are three Use Tables at basic prices, one for total inputs, one for domestic inputs and one for imported inputs. These three tables, along with the Table of Trade Margins and the Table of Taxes less subsidies, form what are known as the Intermediate Tables for the IO Tables.

Symmetric Input-Output Tables

There are three IO Tables; one for each of the Use at basic prices tables, a Totals Table, a Domestic IO Table, which refers to the consumption of domestically produced products and an Imports IO Table, which refers to the consumption of imported products. The symmetric tables present the Use Tables as product by product (as opposed to product by industry) and can be seen as a blending of the Supply Table and the Use Table into a single table. The tables allow for the examination of both inputs (columns) and outputs (rows) simultaneously, and its main value lies in being able to examine the use of products in the production of other products within the Irish economy.

A summary of the IOT for domestic product flows is presented in Table 2.7 below. The summary table easily highlights the tables' symmetry, and how the inputs are equal to the outputs across product categories.

Multipliers

The Domestic IO Table is used to calculate Coefficients of domestic product flows and the Leontief Inverse of domestic flows with multipliers for other inputs. The Table of Coefficients explains the direct input requirements per unit of output, while the Leontief Inverse shows the inputs required per unit of final demand. If there is an increase in demand for a particular product, we assume there will be an increase in output of that product (direct effect), but there will also be an increase in demand for other products used in the production of that first product (indirect effect). This table measures the direct and indirect impacts on the economy from the increase in demand for domestic output of a given product. Output multipliers are the sum of the direct and indirect effects to a unit increase in final use.

Using Table 2.11 below, this can be interpreted as follows for products of Agriculture (CPA 01) as an example. Each €1 of final demand for domestic output of products of Agriculture requires €1.20 output of domestically produced Agriculture products and €0.27 of all other domestically produced products. The €0.27 is further broken down into product categories in the Leontief Inverse Table (Table 2.13), giving an indication of how the increase in one area of the economy will impact other areas of the economy. More information on interpreting the Leontief Inverse Table can be found in the Background Notes.

Note that only Type I multipliers are available (direct and indirect effect). There are also Type II multipliers which include the induced effects of additional demand, these involve more estimation and assumptions, and are not compiled by the CSO.
