Finance is a term for matters regarding the management, creation, and study of money and investments. Specifically, it deals with the questions of how an individual, company or government acquires money – called capital in the context of a business – and how they spend or invest that money. Finance is then often divided into the following broad categories: personal finance, corporate finance, and public finance.
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."
In economics, inflation refers to a general progressive increase in prices of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualised percentage change in a general price index.
In economics and political science, fiscal policy is the use of government revenue collection and expenditure to influence a country's economy. The use of government revenues and expenditures to influence macroeconomic variables developed as a result of the Great Depression, when the previous laissez-faire approach to economic management became unpopular. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorized that government changes in the levels of taxation and government spending influences aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation and to increase employment. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilize the economy over the course of the business cycle.
Monetary policy concerns the actions of a central bank or other regulatory authorities that determine the size and rate of growth of the money supply. For example, in the United States, the Federal Reserve is in charge of monetary policy, and implements it primarily by performing operations that influence short-term interest rates.
In macroeconomics, the money supply refers to the total volume of money held by the public at a particular point in time in an economy. There are several ways to define "money", but standard measures usually include currency in circulation and demand deposits. The central bank of each country may use a definition of what constitutes money for its purposes.
Monetary policy is the policy adopted by the monetary authority of a nation to control either the interest rate payable for very short-term borrowing or the money supply, often as an attempt to reduce inflation or the interest rate, to ensure price stability and general trust of the value and stability of the nation's currency.
The Bank of Korea is the central bank of the Republic of Korea and issuer of Korean Republic won. It was established on 12 June 1950 in Seoul, South Korea.
In economics, crowding out is a phenomenon that occurs when increased government involvement in a sector of the market economy substantially affects the remainder of the market, either on the supply or demand side of the market.
Money creation, or money issuance, is the process by which the money supply of a country, or of an economic or monetary region, is increased. In most modern economies, most of the money supply is in the form of bank deposits. Central banks monitor the amount of money in the economy by measuring monetary aggregates, consisting of cash and bank deposits. Money creation occurs when the quantity of monetary aggregates increase.
The real economy concerns the production, purchase and flow of goods and services within an economy. It is contrasted with the financial economy, which concerns the aspects of the economy that deal purely in transactions of money and other financial assets, which represent ownership or claims to ownership of real sector goods and services.
Credit rationing is the limiting by lenders of the supply of additional credit to borrowers who demand funds at a set quoted rate by the financial institution. It is an example of market failure, as the price mechanism fails to bring about equilibrium in the market. It should not be confused with cases where credit is simply "too expensive" for some borrowers, that is, situations where the interest rate is deemed too high. With credit rationing, the borrower would like to acquire the funds at the current rates, and the imperfection is the absence of supply from the financial institutions, despite willing borrowers. In other words, at the prevailing market interest rate, demand exceeds supply, but lenders are willing neither to lend enough additional funds to satisfy demand, nor to raise the interest rate they charge borrowers because they are already maximising profits, or are using a cautious approach to continuing to meet their capital reserve requirements.
Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.
The financial accelerator in macroeconomics is the process by which adverse shocks to the economy may be amplified by worsening financial market conditions. More broadly, adverse conditions in the real economy and in financial markets propagate the financial and macroeconomic downturn.
In financial economics, a liquidity crisis refers to an acute shortage of liquidity. Liquidity may refer to market liquidity, funding liquidity, or accounting liquidity. Additionally, some economists define a market to be liquid if it can absorb "liquidity trades" without large changes in price. This shortage of liquidity could reflect a fall in asset prices below their long run fundamental price, deterioration in external financing conditions, reduction in the number of market participants, or simply difficulty in trading assets.
The interbank lending market is a market in which banks lend funds to one another for a specified term. Most interbank loans are for maturities of one week or less, the majority being over day. Such loans are made at the interbank rate. A sharp decline in transaction volume in this market was a major contributing factor to the collapse of several financial institutions during the financial crisis of 2007–2008.
The credit channel mechanism of monetary policy describes the theory that a central bank's policy changes affect the amount of credit that banks issue to firms and consumers for purchases, which in turn affects the real economy.
Monetary policy is the monitoring and control of money supply by a central bank, such as the Federal Reserve Board in the United States of America, and the Bangko Sentral ng Pilipinas in the Philippines. This is used by the government to be able to control inflation, and stabilize currency. Monetary Policy is considered to be one of the two ways that the government can influence the economy – the other one being Fiscal Policy. Monetary Policy is generally the process by which the central bank, or government controls the supply and availability of money, the cost of money, and the rate of interest.
The asset price channel is the monetary transmission channel that is responsible for the distribution of the effects induced by monetary policy decisions made by the central bank of a country that affect the price of assets. These effects on the prices of assets will in turn affect the economy.
The interest rate channel is a mechanism of monetary policy, whereby a policy-induced change in the short-term nominal interest rate by the central bank affects the price level, and subsequently output and employment.
