Gross private domestic investment is the
measure of physical investment used in computing GDP in the
measurement of nations' economic activity. This is an important
component of GDP because it provides an indicator of the future
productive capacity of the economy. It includes replacement
purchases plus net additions to capital assets plus investments in
inventories
- Fixed investment is the category that includes the capital
goods that best reflects what most people consider capital
investment, and it is generally about 95 to 97 percent of gross
private domestic investment. This category includes factories,
machinery, tools, and buildings. More specifically, fixed
investment is divided into two major subcategories: nonresidential
and residential.
- The nonresidential category, once again, typifies what most
people think of as business investment. Coming in at just under 70
percent of gross private domestic investment and just over 70
percent of fixed investment, this subcategory includes structures
(buildings, pipelines, oil wells) and producers' durable equipment
(computers, machinery, vehicles). Structures are about one-fourth
of nonresidential fixed investment and producers' durable equipment
is about three-fourths.
- The residential category primarily includes houses and
apartments, and comes in at just under 30 percent of both fixed
investment and gross private domestic investment. Like
nonresidential fixed investment, residential fixed investment is
divided into structures and producers' durable equipment.
Structures are separated into single family (houses) and
multifamily (apartments). Of some importance, single family
structures can be owned by either a business or an individual. In
other words, the production of an owner-occupied house is included
as gross private domestic investment in the National Income and
Product Accounts. This is the only notable purchase made by the
household sector that is not included as a personal consumption
expenditure. Structures are about 98 percent of this residential
category and producers' durable equipment is the remaining 2
percent.
so increase in the the rate for Fixed investment tends to affect
both residential and non residential investment. As, investors now
will invest less. Most of the investments will be made by govt. i.e
both type of properties will be owned by public sector.
