Feldstein–Horioka Puzzle
The Feldstein–Horioka puzzle is a widely discussed problem in macroeconomics and international finance, which was first documented by Martin Feldstein and Charles Horioka in a 1980 paper. Economic theory assumes that if investors can easily invest anywhere in the world, acting rationally they would invest in countries offering the highest return per unit of investment. This would drive up the price of the investment until the return across different countries is similar. The discussion stems from the economic theory that capital flows act to equalize marginal product of capital across nations. In other words, money flows from lower to higher marginal products until the increased investment equalizes the return with that obtainable elsewhere. According to standard economic theory, in the absence of regulation in international financial markets, the savings of any country would flow to countries with the most productive investment opportunities. Therefore, domestic saving rates woul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macroeconomics
Macroeconomics (from the Greek prefix ''makro-'' meaning "large" + ''economics'') 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." Macroeconomists study topics such as Gross domestic product, GDP (Gross Domestic Product), unemployment (including Unemployment#Measurement, unemployment rates), national income, price index, price indices, output (economics), output, Consumption (economics), consumption, inflation, saving, investment (macroeconomics), investment, Energy economics, energy, international trade, and international finance. ...

Backus–Kehoe–Kydland Puzzle
In economics, the Backus–Kehoe–Kydland consumption correlation puzzle, also known as the BKK puzzle, is the observation that consumption is much less correlated across countries than output. Statement In an Arrow–Debreu economy, i.e. an economy with a complete set of state-contingent markets, country-specific output risks should be pooled and domestic consumption growth should not depend heavily on country-specific income shocks. So according to theory we should observe that consumption is much more correlated across countries than output. What Backus, Kehoe and Kydland found in their article from 1992 was the opposite, namely that consumption is much less correlated across countries than output. Backus, Kehoe, and Kydland (1992) calculate the correlation of HP-filtered consumption and output for 11 advanced countries relative to the US. The measured average consumption correlation was .19, whereas the average output correlation was .31. Obstfeld and Rogoff (1996) rep ...

Economic Puzzles
A puzzle in economics is a situation where the implication of theory is inconsistent with observed economic data. An example is the equity premium puzzle, which relates to the fact that over the last two hundred years, the risk premium of stocks over bonds has been around 5.5%, much larger than expected from theory. The equity premium puzzle was first documented by Mehra and Prescot (1985). List of puzzles :''See also :Economic puzzles; Financial economics #Challenges and criticism.'' *Equity premium puzzle *Home bias in trade puzzle *Equity home bias puzzle *Consumption correlations puzzle Consumption may refer to: *Resource consumption *Tuberculosis, an infectious disease, historically * Consumption (ecology), receipt of energy by consuming other organisms * Consumption (economics), the purchasing of newly produced goods for curren ... * Feldstein-Horioka puzzle * Forward premium anomaly * Real exchange rate puzzles *Retirement-consumption puzzle *Missing trade puzzle, als ...

Lucas Paradox
In economics, the Lucas paradox or the Lucas puzzle is the observation that capital does not flow from developed countries to developing countries despite the fact that developing countries have lower levels of capital per worker. Classical economic theory predicts that capital should flow from rich countries to poor countries, due to the effect of diminishing returns of capital. Poor countries have lower levels of capital per worker – which explains, in part, why they are poor. In poor countries, the scarcity of capital relative to labor should mean that the returns related to the infusion of capital are higher than in developed countries. In response, savers in rich countries should look at poor countries as profitable places in which to invest. In reality, things do not seem to work that way. Surprisingly little capital flows from rich countries to poor countries. This puzzle, famously discussed in a paper by Robert Lucas in 1990, is often referred to as the "Lucas Paradox. ...

Bank For International Settlements
The Bank for International Settlements (BIS) is an international financial institution owned by central banks that "fosters international monetary and financial cooperation and serves as a bank for central banks". The BIS carries out its work through its meetings, programmes and through the Basel Process – hosting international groups pursuing global financial stability and facilitating their interaction. It also provides banking services, but only to central banks and other international organizations. It is based in Basel, Switzerland, with representative offices in Hong Kong and Mexico City. History The BIS was established in 1930 by an intergovernmental agreement between Germany, Belgium, France, the United Kingdom, Italy, Japan, the United States, and Switzerland. It opened its doors in Basel, Switzerland, on 17 May 1930. The BIS was originally intended to facilitate reparations imposed on Germany by the Treaty of Versailles after World War I, and to act as the truste ...

Patriotism
Patriotism is the feeling of love, devotion, and sense of attachment to one's country. This attachment can be a combination of many different feelings, language relating to one's own homeland, including ethnic, cultural, political or historical aspects. It encompasses a set of concepts closely related to nationalism, mostly civic nationalism and sometimes cultural nationalism. Some manifestations of patriotism emphasize the "land" element in love for one's native land and use the symbolism of agriculture and the soil – compare ''Blut und Boden''. Terminology and usage An excess of patriotism in the defense of a nation is called chauvinism; another related term is '' jingoism''. The English word 'Patriot' derived from "Compatriot," in the 1590s, from Middle French "Patriote" in the 15th century. The French word's "Compatriote" and "Patriote" originated directly from Late Latin Patriota "fellow-countryman" in the 6th century. From Greek Patriotes "fellow countryman," f ...

Homo Economicus
The term ''Homo economicus'', or economic man, is the portrayal of humans as agents who are consistently rational and narrowly self-interested, and who pursue their subjectively defined ends optimally. It is a word play on ''Homo sapiens'', used in some economic theories and in pedagogy. In game theory, ''Homo economicus'' is often modelled through the assumption of perfect rationality. It assumes that agents always act in a way that maximize utility as a consumer and profit as a producer, and are capable of arbitrarily complex deductions towards that end. They will always be capable of thinking through all possible outcomes and choosing that course of action which will result in the best possible result. The rationality implied in ''Homo economicus'' does not restrict what sort of preferences are admissible. Only naive applications of the ''Homo economicus'' model assume that agents know what is best for their long-term physical and mental health. For example, an agent's u ...

International Monetary Fund
The International Monetary Fund (IMF) is a major financial agency of the United Nations, and an international financial institution, headquartered in Washington, D.C., consisting of 190 countries. Its stated mission is "working to foster global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty around the world." Formed in 1944, started on 27 December 1945, at the Bretton Woods Conference primarily by the ideas of Harry Dexter White and John Maynard Keynes, it came into formal existence in 1945 with 29 member countries and the goal of reconstructing the international monetary system. It now plays a central role in the management of balance of payments difficulties and international financial crises. Countries contribute funds to a pool through a quota system from which countries experiencing balance of payments problems can borrow money. , the fund had XDR 477 billion (a ...

Central Bank
A central bank, reserve bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union, and oversees their commercial banking system. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Most central banks also have supervisory and regulatory powers to ensure the stability of member institutions, to prevent bank runs, and to discourage reckless or fraudulent behavior by member banks. Central banks in most developed nations are institutionally independent from political interference. Still, limited control by the executive and legislative bodies exists. Activities of central banks Functions of a central bank usually include: * Monetary policy: by setting the official interest rate and controlling the money supply; *Financial stability: acting as a government's banker and as the bankers' bank ("lender of last resort"); * Reserve management: managing a country's ...

Information Asymmetry
In contract theory and economics, information asymmetry deals with the study of decisions in transactions where one party has more or better information than the other. Information asymmetry creates an imbalance of power in transactions, which can sometimes cause the transactions to be inefficient, causing market failure in the worst case. Examples of this problem are adverse selection, moral hazard, and monopolies of knowledge. A common way to visualise information asymmetry is with a scale with one side being the seller and the other the buyer. When the seller has more or better information the transaction will more likely occur in the seller's favour ("the balance of power has shifted to the seller"). An example of this could be when a used car is sold, the seller is likely to have a much better understanding of the car's condition and hence its market value than the buyer, who can only estimate the market value based on the information provided by the seller and their own a ...

Equity Home Bias Puzzle
The Home bias puzzle is the term given to describe the fact that individuals and institutions in most countries hold only modest amounts of foreign equity, and tend to strongly favor company stock from their home nation. This finding is regarded as puzzling, since observed returns on national equity portfolios suggest substantial benefits from international diversification. Maurice Obstfeld and Kenneth Rogoff identified this as one of the six major puzzles in international macroeconomics. Overview Home bias in equities is a behavioral finance phenomenon and it was first studied in an academic context by Kenneth French and James M. Poterba (1991) and Tesar and Werner (1995). Coval and Moskowitz (1999) showed that home bias is not limited to international portfolios, but that the preference for investing close to home also applies to portfolios of domestic stocks. Specifically, they showed that U.S. investment managers often exhibit a strong preference for locally headquartered f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Finance
International finance (also referred to as international monetary economics or international macroeconomics) is the branch of financial economics broadly concerned with monetary and macroeconomic interrelations between two or more countries. International finance examines the dynamics of the global financial system, international monetary systems, balance of payments, exchange rates, foreign direct investment, and how these topics relate to international trade. 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. Some examples of key concepts within international finance are the Mundell–Fleming model, the optimum currency area theory, purchasing power parity, interest rate pari ...
