Sometimes referred to as multinational finance, international finance is additionally concerned with matters of international financial management. Investors and multinational corporations must assess and manage international risks such as political risk and foreign exchange risk, including transaction exposure, economic exposure, and translation exposure.[4][5]
The foreign exchange and political risk dimensions of international finance largely stem from sovereign nations having the right and power to issue currencies, formulate their own economic policies, impose taxes, and regulate movement of people, goods, and capital across their borders.[6]
The idea of fiat currency was established just over a thousand years ago in China during the Yuan, Tang, Song and Ming dynasties. In the Tang Dynasty (618-907) there was a high demand for metallic currency that exceeded the supply of precious metals. The people were already familiar with the use of credit notes, and they rapidly began accepting pieces of paper or paper drafts.[7]
A shortage of coins forced these people to change from coins to notes. During the Song Dynasty (960-1276), there was a booming business in the Sichuan region that led to a shortage of copper money. This led to traders issuing private notes covered by a monetary reserve. This was considered to be the first ever legal tender. Paper money became the only legal tender in the Yuan Dynasty (1276-1367) and issuing of notes was conferred to the Ministry of Finance during the Ming Dynasty (1368-1644).[7] Fiat money can serve as a good currency if it can handle the role that a nation's economy needs of its monetary unit: storing value, providing a numerical account, and facilitating exchange. It also has excellent seigniorage, meaning it is more cost-efficient than a currency directly tied to produce than a currency directly tied to a commodity.[8]
On the International stage fiat currencies were not truly relevant until the US removed its currency from the gold standard in 1971.[8] At this point other nations followed suit creating an environment where an infinite amount of money could be created. Before this, a nation's currency—which was unaccredited by precious metals—would not be accepted in exchange for goods and services outside of the host country where it was produced.[9]
The Establishment of the International Monetary Fund (IMF) and the World Bank are one of the most significant turning points in the History of international finance. Through Decades of negotiation between international powers and the persistence of economic superpowers no single event inspired unity of determining the fair rules of trade and monetary policy than the Second World War. In Bretton Woods, New Hampshire, delegates from 44 nations gathered to determine what would be the rules for international trade after the war.[10]
After the Bretton Woods Conference was completed the framework for the IMF and World Bank were laid out and begun to be developed. As a result, international trade skyrocketed since exchange between countries and between continents finally had a measurable way to determine exchange rates and fair value of currency.[11] Individual countries' banks were no longer the determining factor in determining a fair exchange rate, removing inconsistencies between individual countries' monetary systems.[12]
The Bretton Woods system did not last very long, as after WW2 the United States was the physical owner of most of the world's gold supply. This meant countries' currencies were supposed to be pegged to a resource over which the US had a near monopoly. This state of affairs only lasted around 20 years as most notably in 1971 the French who were skeptical of the US dollar being the world's reserve currency reclaimed most of their gold that they exported to the US for protection.[13] This action was inherently a destabilizing force to the US dollar since at any time before this individuals or businesses were able to exchange their US dollars for gold. Many other nations followed suit in a metaphorical “Gold Rush'' to get gold from the US by exchanging dollars. The result of this action was the world's reserve currency, the US dollar, no longer being pegged to gold from 1971, with Richard Nixon removing the convertibility factor of the US dollar. This fundamentally changed international finance as no longer was the world's currency based on anything physical, it transitioned into a fiat currency.[14]

With Transfinancial Economics it would be possible to get a far more accurate understanding of Macroeconomics in Real-Time. This is revolutionary, and goes way beyond the limited claims of this Wikipedia article. http://www.p2pfoundation.net/Transfinancial_Economics RS
Macroeconomics (from the Greek prefix makro- meaning "large" and economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole, rather than individual markets. This includes national, regional, and global economies.[1][2] With microeconomics, macroeconomics is one of the two most general fields in economics.
Macroeconomists study aggregated indicators such as GDP, unemployment rates, and price indexes to understand how the whole economy functions. Macroeconomists develop models that explain the relationship between such factors as national income, output, consumption, unemployment, inflation, savings, investment, international trade and international finance. In contrast, microeconomics is primarily focused on the actions of individual agents, such as firms and consumers, and how their behavior determines prices and quantities in specific markets.
While macroeconomics is a broad field of study, there are two areas of research that are emblematic of the discipline: the attempt to understand the causes and consequences of short-run fluctuations in national income (the business cycle), and the attempt to understand the determinants of long-run economic growth (increases in national income). Macroeconomic models and their forecasts are used by governments to assist in the development and evaluation of economic policy.
Macroeconomics encompasses a variety of concepts and variables, but there are three central topics for macroeconomic research.[3] Macroeconomic theories usually relate the phenomena of output, unemployment, and inflation. Outside of macroeconomic theory, these topics are also important to all economic agents including workers, consumers, and producers.
National output is the total value of everything a country produces in a given time period. Everything that is produced and sold generates income. Therefore, output and income are usually considered equivalent and the two terms are often used interchangeably. Output can be measured as total income, or, it can be viewed from the production side and measured as the total value of final goods and services or the sum of all value added in the economy.[4]
Macroeconomic output is usually measured by Gross Domestic Product (GDP) or one of the other national accounts. Economists interested in long-run increases in output study economic growth. Advances in technology, accumulation of machinery and other capital, and better education and human capital all lead to increased economic output over time. However, output does not always increase consistently. Business cycles can cause short-term drops in output called recessions. Economists look for macroeconomic policies that prevent economies from slipping into recessions and that lead to faster long-term growth.
A chart using US data showing the relationship between economic growth and unemployment expressed by Okun's law. The relationship demonstrates cyclical unemployment. Economic growth leads to a lower unemployment rate.
The amount of unemployment in an economy is measured by the unemployment rate, the percentage of workers without jobs in the labor force. The labor force only includes workers actively looking for jobs. People who are retired, pursuing education, or discouraged from seeking work by a lack of job prospects are excluded from the labor force.
Unemployment can be generally broken down into several types that are related to different causes.
Classical unemployment occurs when wages are too high for employers to be willing to hire more workers.
Consistent with classical unemployment, frictional unemployment occurs when appropriate job vacancies exist for a worker, but the length of time needed to search for and find the job leads to a period of unemployment.[5]
Structural unemployment covers a variety of possible causes of unemployment including a mismatch between workers' skills and the skills required for open jobs.[6] Large amounts of structural unemployment can occur when an economy is transitioning industries and workers find their previous set of skills are no longer in demand. Structural unemployment is similar to frictional unemployment since both reflect the problem of matching workers with job vacancies, but structural unemployment covers the time needed to acquire new skills not just the short term search process.[7]
While some types of unemployment may occur regardless of the condition of the economy, cyclical unemployment occurs when growth stagnates. Okun's law represents the empirical relationship between unemployment and economic growth.[8] The original version of Okun's law states that a 3% increase in output would lead to a 1% decrease in unemployment.[9]
The ten-year moving averages of changes in price level and growth in money supply (using the measure of M2, the supply of hard currency and money held in most types of bank accounts) in the US from 1875 to 2011. Over the long run, the two series show a close relationship.
A general price increase across the entire economy is called inflation. When prices decrease, there is deflation. Economists measure these changes in prices with price indexes. Inflation can occur when an economy becomes overheated and grows too quickly. Similarly, a declining economy can lead to deflation. Central bankers, who control a country's money supply, try to avoid changes in price level by using monetary policy. Raising interest rates or reducing the supply of money in an economy will reduce inflation. Inflation can lead to increased uncertainty and other negative consequences. Deflation can lower economic output. Central bankers try to stabilize prices to protect economies from the negative consequences of price changes.
Changes in price level may be result of several factors. The quantity theory of money holds that changes in price level are directly related to changes in the money supply. Most economists believe that this relationship explains long-run changes in the price level.[10] Short-run fluctuations may also be related to monetary factors, but changes in aggregate demand and aggregate supply can also influence price level. For example, a decrease in demand because of a recession can lead to lower price levels and deflation. A negative supply shock, like an oil crisis, lowers aggregate supply and can cause inflation.
The AD-AS model has become the standard textbook model for explaining the macroeconomy.[11] This model shows the price level and level of real output given the equilibrium in aggregate demand and aggregate supply. The aggregate demand curve's downward slope means that more output is demanded at lower price levels.[12] The downward slope is the result of three effects: the Pigou or real balance effect, which states that as real prices fall, real wealth increases, so consumers demand more goods; the Keynes or interest rate effect, which states that as prices fall the demand for money declines causing interest rates to decline and borrowing for investment and consumption to increase; and the net export effect, which states that as prices rise, domestic goods become comparatively more expensive to foreign consumers and thus exports decline.[12]
In the conventional Keynesian use of the AS-AD model, the aggregate supply curve is horizontal at low levels of output and becomes inelastic near the point of potential output, which corresponds with full employment.[11] Since the economy cannot produce beyond more than potential output, any AD expansion will lead to higher price levels instead of higher output.
A traditional AS–AD diagram showing an shift in AD and the AS curve becoming inelastic beyond potential output.
The AD–AS diagram can model a variety of macroeconomic phenomena including inflation. When demand for goods exceeds supply there is an inflationary gap where demand-pull inflation occurs and the AD curve shifts upward to a higher price level. When the economy faces higher costs, cost-push inflation occurs and the AS curve shifts upward to higher price levels.[13] The AS–AD diagram is also widely used as pedagogical tool to model the effects of various macroeconomic policies.[14]
The IS–LM model represents the equilibrium in interest rates and output given by the equilibrium in the goods and money markets.[15] The goods market is represented by the equilibrium in investment and saving (IS), and the money market is represented by the equilibrium between the money supply and liquidity preference.[16] The IS curve consists of the points where investment, given the interest rate, is equal to savings, given output.[17]
The IS curve is downward sloping because output and the interest rate have an inverse relationship in the goods market: As output increases more money is saved, which means interest rates must be lower to spur enough investment to match savings.[17] The LM curve is upward sloping because interest rates and output have a positive relationship in the money market. As output increases, the demand for money increases, and interest rates increase.[18]
In this example of an IS/LM chart, the IS curve moves to the right, causing higher interest rates (i) and expansion in the "real" economy (real GDP, or Y).
The IS/LM model is often used to demonstrate the effects of monetary and fiscal policy.[15] Textbooks frequently use the IS/LM model, but it does not feature the complexities of most modern macroeconomic models.[15] Nevertheless, these models still feature similar relationships to those in IS/LM.[15]
The neoclassical growth model of Robert Solow has become a common textbook model for explaining economic growth in the long-run. The model begins with a production function where national output is the product of two inputs: capital and labor. The Solow model assumes that labor and capital are used at constant rates without the fluctuations in unemployment and capital utilization commonly seen in business cycles.[19]
An increase in output, economic growth, can only occur because of an increase in the capital stock, a larger population, or technological advancements that lead to higher productivity (Total factor productivity). An increase in the savings rate leads to a temporary increase as the economy creates more capital, which adds to output. However, eventually the depreciation rate will limit the expansion of capital: Savings will be used up replacing depreciated capital, and no savings will remain to pay for an additional expansion in capital. Solow's model suggests that economic growth in terms of output per capita depends solely on technological advances that enhance productivity.[20]
In the 1980s and 1990s endogenous growth theory arose to challenge neoclassical growth theory. This group of models explains economic growth through other factors, like increasing returns to scale for capital and learning-by-doing, that are endogenously determined instead of the exogenous technological improvement used to explain growth in Solow's model.[21]
Typical intervention strategies under different conditions
Macroeconomic policy is usually implemented through two sets of tools: fiscal and monetary policy. Both forms of policy are used to stabilize the economy, which usually means boosting the economy to the level of GDP consistent with full employment.[22]
Central banks implement monetary policy by controlling the money supply through several mechanisms. Typically, central banks take action by issuing money to buy bonds (or other assets), which boosts the supply of money and lowers interest rates, or, in the case of contractionary monetary policy, banks sell bonds and takes money out of circulation. Usually policy is not implemented by directly targeting the supply of money.
Banks continuously shift the money supply to maintain a fixed interest rate target. Some banks allow the interest rate to fluctuate and focus on targeting inflation rates instead. Central banks generally try to achieve high output without letting loose monetary policy create large amounts of inflation.
Conventional monetary policy can be ineffective in situations such as a liquidity trap. When interest rates and inflation are near zero, the central bank cannot loosen monetary policy through conventional means. Central banks can use unconventional monetary policy such as quantitative easing to help increase output. Instead of buying government bonds, central banks implement quantitative easing by buying other assets such as corporate bonds, stocks, and other securities.
This allows lowers interest rates for broader class of assets beyond government bonds. In another example of unconventional monetary policy, the United States Federal Reserve recently made an attempt at such as policy with Operation Twist. Unable to lower current interest rates, the Federal Reserve lowered long-term interest rates by buying long-term bonds and selling short-term bonds to create a flat yield curve.
Fiscal policy is the use of government's revenue and expenditure as instruments to influence the economy. Examples of such tools are expenditure, taxes, debt.
For example, if the economy is producing less than potential output, government spending can be used to employ idle resources and boost output. Government spending does not have to make up for the entire output gap. There is a multiplier effect that boosts the impact of government spending. For example, when the government pays for a bridge, the project not only adds the value of the bridge to output, it also allows the bridge workers to increase their consumption and investment, which also help close the output gap.
The effects of fiscal policy can be limited by crowding out. When government takes on spending projects, it limits the amount of resources available for the private sector to use. Crowding out occurs when government spending simply replaces private sector output instead of adding additional output to the economy. Crowding out also occurs when government spending raises interest rates which limits investment. Defenders of fiscal stimulus argue that crowding out is not a concern when the economy is depressed, plenty of resources are left idle, and interest rates are low.
Fiscal policy can be implemented through automatic stabilizers. Automatic stabilizers do not suffer from the policy lags of discretionary fiscal policy. Automatic stabilizers use conventional fiscal mechanisms but take effect as soon as the economy takes a downturn: spending on unemployment benefits automatically increases when unemployment rises and, in a progressive income tax system, the effective tax rate automatically falls when incomes decline.
Economists usually favor monetary over fiscal policy because it has two major advantages. First, monetary policy is generally implemented by independent central banks instead of the political institutions that control fiscal policy. Independent central banks are less likely to make decisions based on political motives.[22] Second, monetary policy suffers shorter inside lags and outside lags than fiscal policy. Central banks can quickly make and implement decisions while discretionary fiscal policy may take time to pass and even longer to carry out.[22]
In the typical view of the quantity theory, money velocity (V) and the quantity of goods produced (Q) would be constant, so any increase in money supply (M) would lead to a direct increase in price level (P). The quantity theory of money was a central part of the classical theory of the economy that prevailed in the early twentieth century.
Macroeconomics, at least in its modern form,[24] began with the publication of John Maynard Keynes's General Theory of Employment, Interest and Money.[23][25] When the Great Depression struck, classical economists had difficulty explaining how goods could go unsold and workers could be left unemployed. In classical theory, prices and wages would drop until the market cleared, and all goods and labor were sold. Keynes offered a new theory of economics that explained why markets might not clear, which would evolve (later in the 20th century) into a group of macroeconomic schools of thought known as Keynesian economics – also called Keynesianism or Keynesian theory.
In Keynes's theory, the quantity theory broke down because people and businesses tend to hold on to their cash in tough economic times, a phenomenon he described in terms of liquidity preferences. Keynes also explained how the multiplier effect would magnify a small decrease in consumption or investment and cause declines throughout the economy. Keynes also noted the role uncertainty and animal spirits can play in the economy.[24]
The generation following Keynes combined the macroeconomics of the General Theory with neoclassical microeconomics to create the neoclassical synthesis. By the 1950s, most economists had accepted the synthesis view of the macro economy.[24] Economists like Paul Samuelson, Franco Modigliani, James Tobin, and Robert Solow developed formal Keynesian models, and contributed formal theories of consumption, investment, and money demand that fleshed out the Keynesian framework.[26]
Milton Friedman updated the quantity theory of money to include a role for money demand. He argued that the role of money in the economy was sufficient to explain the Great Depression and aggregate demand oriented explanations were not necessary. Friedman argued that monetary policy was more effective than fiscal policy; however, Friedman doubted the government has ability to "fine-tune" the economy with monetary policy. He generally favored a policy of steady growth in money supply instead of frequent intervention.[27]
Friedman also challenged the Phillips curve relationship between inflation and unemployment. Friedman and Edmund Phelps (who was not a monetarist) proposed an "augmented" version of the Phillips curve that excluded the possibility of a stable, long-run tradeoff between inflation and unemployment. When the oil shocks of the 1970s created a high unemployment and high inflation, Friedman and Phelps were vindicated. Monetarism was particularly influential in the early 1980s. Monetarism fell out of favor when central banks found it difficult to target money supply instead of interest rates as monetarists recommended. Monetarism also became politically unpopular when the central banks created recessions in order to slow inflation.
New classical macroeconomics further challenged the Keynesian school. A central development in new classical thought came when Robert Lucas introduced rational expectations to macroeconomics. Prior to Lucas, economists had generally used adaptive expectations where agents were assumed to look at the recent past to make expectations about the future. Under rational expectations, agents are assumed to be more sophisticated. A consumer will not simply assume a 2% inflation rate because that has been the average the past few years; she will look at current monetary policy and economic conditions to make an informed forecast. When new classical economists introduced rational expectations into their models, they showed that monetary policy could only have a limited impact.
Lucas also made an influential critique of Keynesian empirical models. He argued that forecasting models based on empirical relationships would keep producing the same predictions even as the underlying model generating the data changed. He advocated models based on fundamental economic theory that would, in principle, be structurally accurate as economies changed. Following Lucas's critique, new classical economists, led by Edward C. Prescott and Finn E. Kydland created real business cycle (RBC) models of the macroeconomy.[28]
RBC models were created by combining fundamental equations from neo-classical microeconomics. In order to generate macroeconomic fluctuations, RBC models explained recessions and unemployment with changes in technology instead changes in the markets for goods or money. Critics of RBC models argue that money clearly plays an important role in the economy, and the idea that technological regress can explain recent recessions is also implausible.[29] However, technological shocks are only the more prominent of a myriad of possible shocks to the system that can be modeled. Despite questions about the theory behind RBC models, they have clearly been influential in economic methodology.
New Keynesian economists responded to the new classical school by adopting rational expectations and focusing on developing micro-founded models that are immune to the Lucas critique. Stanley Fischer and John B. Taylor produced early work in this area by showing that monetary policy could be effective even in models with rational expectations when contracts locked-in wages for workers. Other new Keynesian economists expanded on this work and demonstrated other cases where inflexible prices and wages led to monetary and fiscal policy having real effects.
Like classical models, new classical models had assumed that prices would be able to adjust perfectly and monetary policy would only lead to price changes. New Keynesian models investigated sources of sticky prices and wages due to imperfect competition,[30] which would not adjust, allowing monetary policy to impact quantities instead of prices.
By the late 1990s economists had reached a rough consensus. The rigidities of new Keynesian theory were combined with rational expectations and the RBC methodology to produce dynamic stochastic general equilibrium (DSGE) models. The fusion of elements from different schools of thought has been dubbed the new neoclassical synthesis. These models are now used by many central banks and are a core part of contemporary macroeconomics.[31]
New Keynesian economics: which developed partly in response to new classical economics, strives to provide microeconomic foundations to Keynesian economics by showing how imperfect markets can justify demand management.
