Public expenditure is spending made by the government of a country on collective or individual needs and wants of [[Public good (economics)|public goods]] and [[public service]]s, such as pension, healthcare, security, [[Free education|education subsidies]], emergency services, infrastructure, etc.<ref>{{cite web|last=Akrani|first=Gaurav|title=Meaning of Public Expenditure|url=http://kalyan-city.blogspot.in/2011/02/what-is-public-expenditure-meaning-and.html|access-date=15 February 2012}}</ref> Until the 19th century, public expenditure was limited due to [[laissez faire]] philosophies. In the 20th century, [[John Maynard Keynes]] argued that the role of public expenditure was pivotal in determining levels of income and [[Distribution of wealth|distribution]] in the economy. Public expenditure plays an important role in the economy as it establishes fiscal policy and provides public goods and services for households and firms.

==Theories of public expenditure== {{Main|Theory of taxation}} Several '''theories of taxation''' exist in [[public economics]].<ref>{{Cite journal |last1=Kind |first1=Hans Jarle |last2=Schjelderup |first2=Guttorm |date=2025-01-30 |title=Taxation and multi-sided platforms: a review |url=https://link.springer.com/article/10.1007/s10797-024-09878-1 |journal=International Tax and Public Finance |volume=32 |issue=3 |pages=895–915 |language=en |doi=10.1007/s10797-024-09878-1 |issn=1573-6970|hdl=11250/3170425 |hdl-access=free }}</ref> Governments can be separated into two distinct types when it comes to their fiscal and monetary sovereignty: currency-issuers and currency-users. Currency-users at all levels (national, regional and local) need to raise revenue from a variety of sources to finance public-sector expenditures. They are not in control of the currency that their jurisdiction transacts in and so are restricted by what revenue they can raise prior to executing spending policies. Currency-issuing governments have no such nominal fiscal restriction. They have an infinite fiscal capacity in that, in principle, they can issue as much of their own currency as they like. However, [[inflation]] constraints currency-issuing government spending in practice.

The details of taxation are guided by two principles: who will benefit, and who can pay. Public expenditure means the expenditure on the developmental and non-developmental activity such as construction of roadways and dams, and other activity.

Rules or principles that govern the expenditure policy of the government are called "canons of public expenditure". Economist George Findlay Shirras<ref>Cambridge University Libraries, [https://archivesearch.lib.cam.ac.uk/agents/people/6477 Shirras, George Findlay, 1885–1955 (economist)], accessed 4 June 2023</ref> laid down the following four canons of public expenditure, although some are understood not to be required:

#Canon of benefit – public spending must be done in a manner that it brings greatest social benefits. #Canon of economy – it says that economy does not mean miserliness. Public expenditure must be made productively and efficiently. #Canon of sanction – public spending should not be made without sanction of an appropriate authority. #Canon of surplus – public revenue should exceed government expenditure, this avoiding a [[budget deficit|deficit]]. Government must prepare a budget to create a surplus.<ref>{{Cite web|last=Muley|first=Ritika|date=29 January 2016|title=Public Expenditure: Causes, Principles and Importance|url=https://www.economicsdiscussion.net/india/public-expenditure/public-expenditure-causes-principles-and-importance/17462|access-date=2021-04-25|website=EconomicsDiscussion.net|language=en-US}}</ref>

Three other canons are: #Canon of elasticity – it says there should be enough scope in expenditure policy.government should be able to increase or decrease it according to the period. #Canon of productivity – public expenditure should encourage production efficiency of the economy. #Canon of equitable distribution – expenditure policy should minimize inequalities and it should be designed in a way to benefit poorer sections.{{cn|date=June 2023}}

===Principle of maximum social advantage=== [[Image:MSS and MSB.JPG|thumb|right|300px|Dalton's Principle of Maximum Social Advantage. Graph showing point of Maximum Social Advantage at point "P"<ref>{{cite web|title=Diminishing Marginal Social Benefit Curve|url=http://kalyan-city.blogspot.in/2011/01/dalton-principle-of-maximum-social.html|access-date=20 February 2012}}</ref>]] The criteria and pre-conditions for arriving at this solution are collectively referred to as the principle of maximum social advantage. Taxation (government revenue) and government expenditure are the two tools. Neither of excess is good for the society, it has to be balanced to achieve maximum social benefit. Dalton called this principle as "Maximum Social Advantage" and [[Arthur Cecil Pigou|Pigou]] termed it as "Maximum Aggregate Welfare".

''Dalton's principle of maximum social advantage'' – maximum satisfaction should be yield by striking a balance between public revenue and expenditure by the government. Economic welfare is achieved when [[marginal utility]] of expenditure = marginal disutility of taxation. He explains this principle with reference to * ''Maximum social benefit (MSB)'' * ''Maximum social sacrifice (MSS)''<ref>{{cite web|title=Dalton's Principle of Maximum Social Advantage|url=http://kalyan-city.blogspot.in/2011/01/dalton-principle-of-maximum-social.html|access-date=20 February 2012}}</ref>

It was introduced by Swedish Economist "[[Erik Lindahl]] in 1919".<ref>[[Lindahl tax]]</ref> According to his theory, determination of public expenditure and taxation will happen on the basis of public preferences which they will reveal themselves. Cost of supplying a good will be taken up by the people.

An increase in government deficit spending "crowds out" private investment by increasing interest rates and lowering the quantity of capital available to the private sector [sic].]] Government spending can be a useful economic policy tool for governments. [[Fiscal policy]] can be defined as the use of government spending and/or taxation as a mechanism to influence an economy.<ref name=":0" /><ref name=":8">{{Cite book|title=Principles of Economics|last=Gregory|first=Mankiw|publisher=Southwestern Publishing Group|year=2014|isbn=9781285165875|edition= Seventh |location=Stamford, CT|oclc=884664951}}</ref> There are two types of fiscal policy: expansionary fiscal policy, and contractionary fiscal policy. Expansionary fiscal policy is an increase in government spending or a decrease in taxation, while contractionary fiscal policy is a decrease in government spending or an increase in taxes. Expansionary fiscal policy can be used by governments to stimulate the economy during a [[recession]]. For example, an increase in government spending directly increases demand for goods and services, which can help increase [[Output (economics)|output]] and employment. On the other hand, contractionary fiscal policy can be used by governments to cool down the economy during an economic boom. A decrease in government spending or an increase in taxes can help reduce inflationary pressures within the economy.<ref name=":0">{{Cite book|title=Principles of Macroeconomics: Economics and the Economy|last=Taylor|first=Timothy|publisher=Textbook Media Press|year=2017|isbn=9780996996334|edition= Fourth |location=Minneapolis|pages=366–340|oclc=1001342630}}</ref> During economic downturns, in the short run, government spending can be changed either via [[Automatic stabilizer|automatic stabilization]] or discretionary stabilization. Automatic stabilization is when existing policies automatically change government spending or taxes in response to economic changes, without the additional passage of laws.<ref name=":1" /><ref name=":0" /> A primary example of an [[automatic stabilizer]] is [[unemployment insurance]] or an employment guarantee, which provide financial assistance to unemployed workers or direct wages to recently unemployed workers, respectively. Discretionary stabilization is when a government takes actions to change government spending or taxes in direct response to changes in the economy. For instance, a government may decide to increase government spending as a result of a recession.<ref name=":1">{{Cite book|title=Public Finance and Public Policy|last=Jonathan|first=Gruber|publisher=Worth Publishers|isbn=9781464143335|edition= Fifth |location=New York|oclc=914290290|date = 28 December 2015}}</ref> With discretionary stabilization, most governments must pass a new law to make changes in government spending.<ref name=":0" />

[[John Maynard Keynes]] was one of the first economists to advocate for government [[deficit spending]] as part of the fiscal policy response to an [[recession|economic contraction]]. According to [[Keynesian economics]], increased government spending raises [[aggregate demand]] and increases [[Consumption (economics)|consumption]], which leads to increased production and faster recovery from recessions. [[Classical economics|Classical economists]], on the other hand, believe that increased government spending exacerbates an [[recession|economic contraction]] by shifting resources from the private sector, which they consider productive, to the public sector, which they consider unproductive.<ref>{{Cite book|title=Macroeconomics for Today|last=Irvin|first=Tucker|publisher=Cengage Learning|year=2012|isbn=9781133435051|edition= 8th |location=Mason, OH|oclc=830731890}}</ref>

In economics, the potential "shifting" in resources from the [[private sector]] to the [[public sector]] as a result of an increase in government [[deficit spending]] is called [[Crowding out (economics)|crowding out]].<ref name=":0" /> The figure to the right depicts an outdated theory for the market for capital, otherwise known as the market for [[loanable funds]]. The downward sloping [[demand curve]] D1 represents demand for private capital by firms and investors, and the upward sloping [[supply curve]] S1 represents savings by private individuals. The initial equilibrium in this market is represented by point A, where the equilibrium quantity of capital is K1 and the equilibrium interest rate is R1. In this theory, if the government increases [[deficit spending]], it will borrow money from the private [[capital market]] and reduce the supply of savings to S2. The new equilibrium is at point B, where the interest rate has increased to R2 and the quantity of capital available to the private sector has decreased to K2. The government has essentially made borrowing more expensive and has taken away savings from the market, which "crowds out" some private investment. The crowding out of private investment could limit the economic growth from the initial increase in government spending.<ref name=":1" /><ref name=":8" />

A closer understanding of government fiscal operations contradicts the above loanable funds theory. In fact, in the first instance and all else equal, increased government deficit spending ''increases'' liquidity in the banking system, thereby pushing down on interest rates. Government borrowing is the act of swapping the excess bank reserves created via the increased deficit spending with Treasury securities, thus draining this excess liquidity back down to pre-spending levels. There is no "loanable funds" pool of currency in reality. Crowding out only refers to the shift of real resources from private to public use, not the crowding out of nominal private investment. Government deficit spending increases the net financial assets available to the non-government sector.<ref>{{Cite journal |last=Pilkington |first=Philip Clarke |date=13 October 2014 |title=Endogenous Money and the Natural Rate of Interest: The Reemergence of Liquidity Preference and Animal Spirits in the Post-Keynesian Theory of Capital Markets |url=https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2509361 |journal=SSRN Electronic Journal |doi=10.2139/ssrn.2509361 |ssrn=2509361 |via=SSRN}}</ref><ref>Taylor, Lance (2016) – "The "Natural" Interest Rate and Secular Stagnation: Loanable Funds Macro Models Don't Fit Today's Institutions or Data – Institute of New Economic Thinking</ref>

Government spending on goods and services for current use to directly satisfy individual or collective needs of the members of the community is called [[government final consumption expenditure]] (GFCE) It is a purchase from the national accounts "use of income account" for goods and services directly satisfying of individual needs (''individual consumption'') or collective needs of members of the community (''collective consumption''). GFCE consists of the value of the goods and services produced by the government itself other than own-account [[capital formation]] and sales and of purchases by the government of goods and services produced by market producers that are supplied to households—without any transformation—as "social transfers" in kind.<ref>F. Lequiller, D. Blades: Understanding National Accounts, Paris: OECD 2006, pp. 127–30</ref>

On the other hand, global health spending continues to increase and rise rapidly – to US$7.8&nbsp;trillion in 2017 or about 10% of GDP and $1.80 per capita – up from US£7.6&nbsp;trillion in 2016. In addition, about 605 of this spending was public and 40% private, with donor funding representing less than 0.2% of the total although the health spending in real terms has risen by 3.79% in a year while global GDP had grown by 3.0%.

According to the World Health Organisation (WHO), the increase in health spending in low-income countries, and it rose by 7.8% a year between 2000 and 2017, while their economies grew by 6.4%, it is explained in the figure. However, the middle-income economies health spending grew more than 6%, and average annual growth in high-income countries was 3.5%, which is about twice as fast as economic growth. In contrast, health spending by the high-income countries continues to represent to be the largest share of global spending, which is about 81%, despite it covers only 16% of world's population; although it down from 87% in 2000. The primary drivers of this change in global spending on healthcare are India and China, which they moved to higher-income groups. Furthermore, just over 40% of the world population lived in low-income countries, which is now dropped to 10%. Moreover, significant spending increments were in upper-middle-income economies, where population share has more than &nbsp;doubled over the period, and share of global health spending nearly also doubled due to China and India's vast population joining that group. Unfortunately, all other spending share income groups had declined.<ref>{{Cite web|url=https://www.who.int/health_financing/documents/health-expenditure-report-2019/en/|archive-url=https://web.archive.org/web/20200120170628/https://www.who.int/health_financing/documents/health-expenditure-report-2019/en/|url-status=dead|archive-date=20 January 2020|title=WHO {{!}} Global Spending on Health: A World in Transition|website=WHO|access-date=2020-04-27}}</ref>

From the continent view, North America, Western Europe, and Oceanic countries have the highest levels of spending, and West Central Asia, and East Africa the lowest, which is closely followed by South Asia, it is explained in the figure.

It is also true that fast economic growth is associated with increased health spending and sustained rapid economic growth between 2000 and 2017. Even more, fast economic growth which is generally associated with the higher government revenues and health spending is mostly located in Asia such as China, India and Indonesia followed by the Middle East and Latin America. In these countries, the real health spending per capita grew by 2.2 times and increased by 0.6 percentage point as per a share of GDP from 2000 to 2017.

In [[economic theory]] or in [[macroeconomics]], investment is the amount purchased of [[Good (economics and accounting)|goods]] which are not consumed but are to be used for future production (i.e. [[Capital (economics)|capital]]). Examples include railroad or factory construction.

Infrastructure spending is considered government investment because it can save money in the long run, but can [[Crowding out (economics)|crowd out]] private investment.<ref name="i311"/> The [[fiscal multiplier]] of government investment spending varies.<ref name="i311">{{cite journal | last=Boehm | first=Christoph E. | title=Government consumption and investment: Does the composition of purchases affect the multiplier? | journal=Journal of Monetary Economics | volume=115 | date=2020 | doi=10.1016/j.jmoneco.2019.05.003 | pages=80–93 | url=https://linkinghub.elsevier.com/retrieve/pii/S0304393219300935 | access-date=2026-02-12| url-access=subscription }}</ref>

Likewise, government spending on [[Infrastructure#Social infrastructure|social infrastructure]], such as [[preventative health care]], can save several hundreds of billions of dollars per year in the U.S., because for example cancer patients are more likely to be diagnosed at [[Cancer staging|Stage I]] where curative treatment is typically a few outpatient visits, instead of at [[Cancer staging|Stage III]] or later in an [[emergency room]] where treatment can involve years of hospitalization and is often terminal.<ref>{{Cite journal | last1 = Hogg | first1 = W. | last2 = Baskerville | first2 = N. | last3 = Lemelin | first3 = J. | title = Cost savings associated with improving appropriate and reducing inappropriate preventive care: Cost-consequences analysis | journal = BMC Health Services Research | volume = 5 | issue = 1 | pages = 20 | year = 2005 | doi = 10.1186/1472-6963-5-20 | pmid = 15755330 | pmc =1079830 | doi-access = free }}</ref>

In the US the total investment in medical and health research and development (R&D) in the US had grown by 27% over the five years from 2013 to 2017, and it is led by industry and the federal government. However, the industry accounted for 67% of total spending in 2017, followed by the federal government at 22%.

Also, academic and research institutions, this includes colleges, and universities, independent research (IRIs), and independent hospital medical research centres also increased spending, dedicating more than $14.2&nbsp;billion of their own funds (endowment, donations etc.) to medical and health R&D in 2017. Although other funding sources – foundations, state and local government, voluntary health associations and professional societies – accounted for 3.7% of total medical and health R&D expenditure.

===Travel=== Although expenditure on ministerial, elected member and staff travel makes up only a small amount of central government expenditure, and the great majority of work trips by officials are undertaken at standard or economy class, the UK's [[National Audit Office (United Kingdom)|National Audit Office]] has noted that this is an aspect of expenditure attracting high levels of public interest.<ref>National Audit Office, [https://www.nao.org.uk/reports/investigation-into-government-travel-expenditure/ Investigation into government travel expenditure] {{Webarchive|url=https://web.archive.org/web/20230626110504/https://www.nao.org.uk/reports/investigation-into-government-travel-expenditure/ |date=26 June 2023 }}, published 11 March 2015, accessed 26 June 2023</ref>

==Government spending by country== === Per capita spending === In 2010 national governments spent an average of $2,376 per person, while the average for the world's 20 largest economies (in terms of GDP) was $16,110 per person. Norway and Sweden expended the most at $40,908 and $26,760 per capita respectively. The federal government of the United States spent $11,041 per person. Other large economy country spending figures include South Korea ($4,557), Brazil ($2,813), Russia ($2,458), China ($1,010), and India ($226).<ref>CIA World Factbook, population data from 2010, Spending and GDP data from 2011.

=== European Union === Public expenditures represented 46.7 percent of total GDP of the European Union in 2018. Countries with the highest percentage of public expenditure were France and Finland with 56 and 53 percent, respectively. The lowest percentage had Ireland with only 25 percent of its GDP. Among the countries of the European Union, the most important function in public expenditure is social protection. Almost 20 percent of GDP of European Union went to social protection in 2018. The highest ratio had Finland and France, both around 24 percent of their GDPs. The country with least social protection expenditure as percent of its GDP was Ireland with 9 percent. The second largest function in public expenditure is expenditure on health. The general government expenditure on health in European Union was over 7 percent of GDP in 2018. The country with highest share of health expenditure in 2018 Denmark with 8.4 percent. The least percentage had Cyprus with 2.7 percent. General public services had 6 percent of total GDP of European Union in 2018, Education around 4.6 percent and all other categories had less than 4.5 percent of the GDP.<ref name=":1a" /><ref>{{Cite web|title=Archive:Evolution of government expenditure by function – Statistics Explained|url=https://ec.europa.eu/eurostat/statistics-explained/index.php/Archive:Evolution_of_government_expenditure_by_function|access-date=2021-04-25|website=ec.europa.eu}}</ref>

Similarly in regard to openness, a campaign by the [[Free Software Foundation Europe]] (FSFE) has called for a principle of "Public Money, Public Code" – that software created using taxpayers' money is developed as [[free and open source software]],<ref>{{cite news |first1=Keywan |last1=Tonekaboni |title=Open CoDE: Open-Source für die öffentliche Verwaltung |url=https://www.heise.de/news/Open-CoDE-Open-Source-fuer-die-oeffentliche-Verwaltung-7238164.html |access-date=28 November 2022 |work=c't Magazin |language=de |archive-date=28 November 2022 |archive-url=https://web.archive.org/web/20221128153535/https://www.heise.de/news/Open-CoDE-Open-Source-fuer-die-oeffentliche-Verwaltung-7238164.html |url-status=live }}</ref><ref>{{cite web |title=Public Money, Public Code |url=https://publiccode.eu/ |website=publiccode.eu |publisher=Free Software Foundation Europe (FSFE) |access-date=28 November 2022 |language=en |archive-date=19 February 2020 |archive-url=https://web.archive.org/web/20200219184118/https://publiccode.eu/ |url-status=live }}</ref> and [[Plan S]] calls for a requirement for scientific publications that result from research funded by public grants being published as [[open access]].<ref>{{cite news |title=European countries demand that publicly funded research be free |url=https://www.economist.com/science-and-technology/2018/09/15/european-countries-demand-that-publicly-funded-research-should-be-free-to-all |access-date=28 November 2022 |newspaper=The Economist |archive-date=2 October 2021 |archive-url=https://web.archive.org/web/20211002110323/https://www.economist.com/science-and-technology/2018/09/15/european-countries-demand-that-publicly-funded-research-be-free |url-status=live }}</ref><ref>{{cite web |title=Input for the development of the UNESCO Recommendation on Open Science |url=https://en.unesco.org/sites/default/files/coalition_s_input_for_unesco_os_recommendation.pdf |access-date=28 November 2022 |archive-date=9 November 2020 |archive-url=https://web.archive.org/web/20201109151138/https://en.unesco.org/sites/default/files/coalition_s_input_for_unesco_os_recommendation.pdf |url-status=live }}</ref><ref>{{cite web |title='Plan S' and 'cOAlition S' – Accelerating the transition to full and immediate Open Access to scientific publications |url=https://www.coalition-s.org/ |website=www.coalition-s.org |access-date=28 November 2022 |archive-date=30 November 2018 |archive-url=https://web.archive.org/web/20181130152305/https://www.coalition-s.org/ |url-status=live }}</ref>

In 2012, following a United States [[Barack Obama|presidential]] Campaign to Cut Waste, the [[Office of Management and Budget]] issued a memorandum to the heads of federal departments and agencies calling for the avoidance of wasteful expenditure, identifying "practical steps" and setting specific targets for reduction of expenditure on travel, [[conference]] attendance and expense, [[real property]] and [[fleet management]].<ref>Office of Management and Budget, [https://obamawhitehouse.archives.gov/sites/default/files/omb/memoranda/2012/m-12-12.pdf Memorandum to the Heads of Executive Departments and Agencies: Promoting Efficient Spending to Support Agency Operations] {{Webarchive|url=https://web.archive.org/web/20230317141945/https://obamawhitehouse.archives.gov/sites/default/files/omb/memoranda/2012/m-12-12.pdf |date=17 March 2023 }}, M-12-12, published 11 May 2012, accessed 26 May 2023</ref>

== History ==

=== Before World War I === At the end of the 19th century average public expenditure was around 10 percent of GDP. In US it was only 7 percent and in countries like United Kingdom, Germany or Netherlands it did not exceed amount of 10 percent. Australia, Italy, Switzerland and France had public expenditure over 12 percent of GDP. It was considered as a significant involvement of government in economy. This average share of public expenditure increased to almost 12 percent before the start of [[World War I]]. Due to the World War I anticipation, the share increased quickly in Austria, France, United Kingdom or Germany.<ref name=":02">{{Cite book|title=Public Spending in the 20th Century|year=2000|isbn=0521662915}}</ref>

=== Effect of World War I and interwar period === The World War I caused a global growth of the public expenditure share in GDP. In United Kingdom, Germany, Italy and France, which were affected a lot by the war, the share of public expenditure even exceeded 25 percent. In interwar period the average share of the public expenditure was still slightly increasing. The United States increased its public expenditure with the New Deal. Other governments also increased public expenditure to create more employment. The increase was accelerated by [[World War II]] anticipation in the second part of the 30s among European countries. In 1937 the amount of average public expenditure share was between 22 and 23 percent, twice as much as before World War I. However, it is fair to mention that part of this increase of public expenditure share was caused by GDP fall. Most of industrialized countries had its GDP over 15 percent before the World War II. Only Australia, Norway and Spain had less than 15 percent of GDP.<ref name=":02" />

=== World War II and post-war period === From the start of the World War I until 1960 the average share of public expenditure in GDP increased slowly from 22 to 28 percent. Most of this increase was given by growth of military spending caused by World War II. Spain, Switzerland and Japan had their public expenditure still below 20 percent of their GDPs.<ref name=":02" />

=== Second half of the 20th century. === The average public expenditure, as a share of GDP, increased rapidly between years 1960 and 1980 from around 28 to 43 percent. No industrial country had this share below 30 percent in 1980. In Belgium, Sweden and Netherlands it was even over 50 percent. In last two decades of 20th century share of public expenditure kept increasing, but the growth significantly slowed down. In 1996 the average public expenditure was around 45 percent, which is in comparison with 1960–1980 period slow increase from year 1980. During 1980–1996 period the public expenditure share even declined in many countries, for example United Kingdom, Belgium, Netherlands etc.<ref name=":02" />

===Growth of public expenditure=== There are several factors that have led to an enormous increase in public expenditure through the years

1) Defense expenditure due to modernization of defense equipment by the navy, army and air force to prepare the country for war or for prevention causes-for-growth-of-public-expenditure. 2) Population growth – It increases with the increase in population, more of investment is required to be done by government on law and order, education, infrastructure, etc. investment in different fields depending on the different age group is required.

3) Welfare activities – social welfare, pensions, etc. * Provision of public and utility services – provision of basic public goods given by government (their maintenance and installation) such as transportation. * Accelerating economic growth – to raise the standard of living of the people. * Price rise – higher price level compels the government to spend an increased amount on purchase of goods and services.<ref>{{cite web|title=Causes for Growth of public expenditure|url=http://www.economicsconcepts.com/public_expenditure.htm|access-date=20 February 2012|archive-date=13 March 2012|archive-url=https://web.archive.org/web/20120313095954/http://www.economicsconcepts.com/public_expenditure.htm|url-status=dead}}</ref> * Increase in public revenue – with the rise in public revenue government is bound to increase the public expenditure. * International obligation – maintenance of socio-economic obligation, cultural exchange etc. (these are indirect expenses of government)

4) Wars and social crises – fighting among people and communities, and prolonged drought or unemployment, earthquake, hurricanes or tornadoes may lead to an increase in public expenditure of a country. This is because it will involve governments to re-plan and allocate resources to finance the reconstruction.

5) Creation of super national organizations – E.g., the United Nations, NATO, European community and other multinational organizations that are responsible for the provision of public goods and services on an international basis, have to be financed out of funds subscribed by member states, thereby adding to their public expenditure.

6) Foreign aid – Acceptance by the richer industrialized countries of their responsibility to help the poor developing countries has channeled some of the increased public expenditure of the donor country into foreign aid programmes.

7) Inflation – This is the general rise in the price level of goods and services. It increases the cost of all activities of the public sector and thus a major factor in growth in money terms of public expenditure

=== Present === Since the late 1980s, the average public expenditure to GDP ratio is increasing slowly. The only industrialized countries that reduced significantly are New Zealand, Ireland and Norway. One of the reasons is growing skepticism about governmental intervention in the economy.<ref name=":02" />
