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 ...

Consumption (economics)
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 is a major concept in economics and is also studied in many other social sciences. Different schools of economists define consumption differently. According to mainstream economists, only the final purchase of newly produced goods and services by individuals for immediate use constitutes consumption, while other types of expenditure — in particular, fixed investment, intermediate consumption, and government spending — are placed in separate categories (see consumer choice). Other economists define consumption much more broadly, as the aggregate of all economic activity that does not entail the design, production and marketing of goods and services (e.g. the selection, adoption, use, disposal and recycling of goods and services). Economists are particularly interested in the relationship betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Bias In Trade Puzzle
The Home bias in trade puzzle is a widely discussed problem in macroeconomics and international finance, first documented by John T. McCallum in an article from 1995. McCallum showed that for the United States and Canada, inter-province trade is 20 times larger than international trade, holding other determinants of trade fixed. Subsequent estimates by John F. Helliwell and others have whittled this bias down to a factor from 6 to 12. This home bias in trade has later been documented among OECD countries. The preferred explanation for this finding has been the presence of formal and informal trade barriers following national borders. Another possible solution to the fact that domestic trade is 20 times larger than international trade could be that domestically traders speak the same language. If presence of formal and informal trade barriers following national borders was the sole reason for this puzzle, home bias should not exist on the subnational level. Wolf (2000) finds, howev ...

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 ...

Consumption Smoothing
Consumption smoothing is an economic concept for the practice of optimizing a person's standard of living through an appropriate balance between savings and consumption over time. An optimal consumption rate should be relatively similar at each stage of a person's life rather than fluctuate wildly. Luxurious consumption at an old age does not compensate for an impoverished existence at other stages in one's life. Since income tends to be hump-shaped across an individual's life, economic theory suggests that individuals should on average have low or negative savings rate at early stages in their life, high in middle age, and negative during retirement. Although many popular books on personal finance advocate that individuals should at all stages of their life set aside money in savings, economist James Choi states that this deviates from the advice of economists.

American Economic Review
The ''American Economic Review'' is a monthly peer-reviewed academic journal published by the American Economic Association. First published in 1911, it is considered one of the most prestigious and highly distinguished journals in the field of economics. The current editor-in-chief is Esther Duflo, an economic professor at the Massachusetts Institute of Technology. The journal is based in Pittsburgh. In 2004, the ''American Economic Review'' began requiring "data and code sufficient to permit replication" of a paper's results, which is then posted on the journal's website. Exceptions are made for proprietary data. Until 2017, the May issue of the ''American Economic Review'', titled the ''Papers and Proceedings'' issue, featured the papers presented at the American Economic Association's annual meeting that January. After being selected for presentation, the papers in the ''Papers and Proceedings'' issue did not undergo a formal process of peer review. Starting in 2018, papers pr ...

Real Exchange-rate Puzzles
The real exchange-rate puzzles is a common term for two much-discussed anomalies of real exchange rates: that real exchange rates are more '' volatile'' and show more ''persistence'' than what most models can account for. These two anomalies are sometimes referred to as the ''purchasing power parity puzzles''. Dornbusch's (1976) exchange rate overshooting hypothesis argued that exchange rate volatility is essentially driven by monetary shocks interacting with sticky prices. This model can account for real exchange rate volatility, but does not say anything about the volatility of relative to output or the persistence of the real exchange rate movements. Chari, Kehoe and McGrattan (2002) showed how a model with two countries and where prices were only allowed to change once-a-year had the potential to simultaneously account for the volatility of U.S. output and real exchange rates. These two anomalies are related to, but should not be confused with, the Backus-Smith consumpti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Kenneth Rogoff
Kenneth Saul Rogoff (born March 22, 1953) is an American economist and chess Grandmaster. He is the Thomas D. Cabot Professor of Public Policy and professor of economics at Harvard University. Early life Rogoff grew up in Rochester, New York. His father was a professor of radiology at the University of Rochester. Rogoff received a BA and MA from Yale University '' summa cum laude'' in 1975, and a PhD in Economics from the Massachusetts Institute of Technology in 1980. Chess At sixteen Rogoff dropped out of high school to concentrate on chess. He won the United States Junior Championship in 1969 and spent the next several years living primarily in Europe and playing in tournaments there. However, at eighteen he made the decision to go to college and pursue a career in economics rather than to become a professional player, although he continued to play and improve for several years afterward. Rogoff was awarded the IM title in 1974, and the GM title in 1978. He was 3rd in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are ''linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the so-called demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However ...
