Leakage (economics)

Last updated

In economics, a leakage is a diversion of funds from some iterative process. For example, in the Keynesian depiction of the circular flow of income and expenditure, leakages are the non-consumption uses of income, including saving, taxes, and imports. In this model, leakages are equal in quantity to injections of spending from outside the flow at the equilibrium aggregate output. The model is best viewed as a circular flow between national income, output, consumption, and factor payments. Savings, taxes, and imports are "leaked" out of the main flow, reducing the money available in the rest of the economy. Imported goods are one way this may happen, transferring money earned in the country to another one. [1]

The simplest possible model of credit creation assumes all loans borrowed from banks in a fractional-reserve banking system are re-deposited to the system. This allows simple calculation of the amount of credit created. In practice, though, cash leakages occur in the form of sums of money borrowed from banks but not re-deposited, and in the form of funds deposited in banks but not lent out. Cash leakage, in this case, lowers the ability of credit creation. [2]

Leakage is a common problem involving TNCs (Transnational corporations). Large companies have factories or production facilities in less developed countries, these factories create wealth for the company which is then not transferred to the economy of the host country and instead to that of the corporation involved. The economic value of goods and/or profits lost here is leakage. [3]

Gross domestic product Market value of goods and services produced within a country

Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a specific time period by countries. GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore, using a basis of GDP per capita at purchasing power parity (PPP) may be more useful when comparing living standards between nations, while nominal GDP is more useful comparing national economies on the international market. Total GDP can also be broken down into the contribution of each industry or sector of the economy. The ratio of GDP to the total population of the region is the per capita GDP and the same is called Mean Standard of Living.

Keynesian economics Group of macroeconomic theories

Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. Instead, it is influenced by a host of factors – sometimes behaving erratically – affecting production, employment, and inflation.

Macroeconomics Study of an economy as a whole

Macroeconomics is a branch of economics dealing with performance, structure, behavior, and decision-making of an economy as a whole. For example, using interest rates, taxes, and government spending to regulate an economy’s growth and stability. This includes regional, national, and global economies. According to a 2018 assessment by economists Emi Nakamura and Jón Steinsson, economic "evidence regarding the consequences of different macroeconomic policies is still highly imperfect and open to serious criticism."

A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), gross national product (GNP), net national income (NNI), and adjusted national income. All are specially concerned with counting the total amount of goods and services produced within the economy and by various sectors. The boundary is usually defined by geography or citizenship, and it is also defined as the total income of the nation and also restrict the goods and services that are counted. For instance, some measures count only goods & services that are exchanged for money, excluding bartered goods, while other measures may attempt to include bartered goods by imputing monetary values to them.

Saving Income which is not immediately spent or otherwise used for consumption

Saving is income not spent, or deferred consumption. Methods of saving include putting money aside in, for example, a deposit account, a pension account, an investment fund, or as cash. Saving also involves reducing expenditures, such as recurring costs. In terms of personal finance, saving generally specifies low-risk preservation of money, as in a deposit account, versus investment, wherein risk is a lot higher; in economics more broadly, it refers to any income not used for immediate consumption. Saving does not automatically include interest.

Interest rate Percentage of a sum of money charged for its use

An interest rate is the amount of interest due per period, as a proportion of the amount lent, deposited, or borrowed. The total interest on an amount lent or borrowed depends on the principal sum, the interest rate, the compounding frequency, and the length of time over which it is lent, deposited, or borrowed.

In economics, the fiscal multiplier is the ratio of change in national income arising from a change in government spending. More generally, the exogenous spending multiplier is the ratio of change in national income arising from any autonomous change in spending. When this multiplier exceeds one, the enhanced effect on national income may be called the multiplier effect. The mechanism that can give rise to a multiplier effect is that an initial incremental amount of spending can lead to increased income and hence increased consumption spending, increasing income further and hence further increasing consumption, etc., resulting in an overall increase in national income greater than the initial incremental amount of spending. In other words, an initial change in aggregate demand may cause a change in aggregate output that is a multiple of the initial change.

Public finance Study of the role of government within the economy

Public finance is the study of the role of the government in the economy. It is the branch of economics that assesses the government revenue and government expenditure of the public authorities and the adjustment of one or the other to achieve desirable effects and avoid undesirable ones. The purview of public finance is considered to be threefold, consisting of governmental effects on:

  1. The efficient allocation of available resources;
  2. The distribution of income among citizens; and
  3. The stability of the economy.
Aggregate demand Total demand for final goods and services in an economy at a given time

In macroeconomics, aggregate demand (AD) or domestic final demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amount of goods and services that will be purchased at all possible price levels. Consumer spending, investment, corporate and government expenditure, and net exports make up the aggregate demand.

Consumption (economics) Using money to obtain an item for use

Consumption is the act of using resources to satisfy current needs and wants. It is seen in contrast to investing, which is spending for acquisition of future income. Consumption a major concept in economics and is also studied in many other social sciences.

Output in economics is the "quantity of goods or services produced in a given time period, by a firm, industry, or country", whether consumed or used for further production. The concept of national output is essential in the field of macroeconomics. It is national output that makes a country rich, not large amounts of money.

A financial system is a system that allows the exchange of funds between financial market participants such as lenders, investors, and borrowers. Financial systems operate at national and global levels. Financial institutions consist of complex, closely related services, markets, and institutions intended to provide an efficient and regular linkage between investors and depositors.

Government spending Government consumptions, investments, and transfer payments

Government spending or expenditure includes all government consumption, investment, and transfer payments. In national income accounting, the acquisition by governments of goods and services for current use, to directly satisfy the individual or collective needs of the community, is classed as government final consumption expenditure. Government acquisition of goods and services intended to create future benefits, such as infrastructure investment or research spending, is classed as government investment. These two types of government spending, on final consumption and on gross capital formation, together constitute one of the major components of gross domestic product.

Circular flow of income

The circular flow of income or circular flow is a model of the economy in which the major exchanges are represented as flows of money, goods and services, etc. between economic agents. The flows of money and goods exchanged in a closed circuit correspond in value, but run in the opposite direction. The circular flow analysis is the basis of national accounts and hence of macroeconomics.

Aggregate income is the total of all incomes in an economy without adjustments for inflation, taxation, or types of double counting. Aggregate income is a form of GDP that is equal to Consumption expenditure plus net profits. 'Aggregate income' in economics is a broad conceptual term. It may express the proceeds from total output in the economy for producers of that output. There are a number of ways to measure aggregate income, but GDP is one of the best known and most widely used.

In economics, personal income refers to an individual's total earnings from wages, investment enterprises, and other ventures. It is the sum of all the incomes received by all the individuals or household during a given period. Personal income is that income which is received by the individuals or households in a country during the year from all sources. In general, it refers to all products and money that you receive.

A global saving glut is a situation in which desired saving exceeds desired investment. By 2005 Ben Bernanke, chairman of the Federal Reserve, the central bank of the United States, expressed concern about the "significant increase in the global supply of saving" and its implications for monetary policies, particularly in the United States. Although Bernanke's analyses focused on events in 2003 to 2007 that led to the 2007–2009 financial crisis, regarding GSG countries and the United States, excessive saving by the non-financial corporate sector (NFCS) is an ongoing phenomenon, affecting many countries. Bernanke's global saving glut (GSG) hypothesis argued that increased capital inflows to the United States from GSG countries were an important reason that U.S. longer-term interest rates from 2003 to 2007 were lower than expected.

Sectoral balances Sectoral analysis framework

The sectoral balances are a sectoral analysis framework for macroeconomic analysis of national economies developed by British economist Wynne Godley.

In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year.
