In economics, the "J curve" is the time path of a country’s trade balance following a devaluation or depreciation of its currency, under a certain set of assumptions. A devalued currency means imports are more expensive, and on the assumption that the volumes of imports and exports change little at first, this causes a fall in the current account (a bigger deficit or smaller surplus). After some time, though, the volume of exports starts to rise because of their lower price to foreign buyers, and domestic consumers buy fewer imports, which have become more expensive for them. Eventually the trade balance moves to a smaller deficit or larger surplus compared to what it was before the devaluation. [1] Likewise, if there is a currency revaluation or appreciation the same reasoning may be applied and will lead to an inverted J curve.
Immediately following the depreciation or devaluation of the currency, the total value of imports will increase and exports remain largely unchanged due in part to pre-existing trade contracts that have to be honored. This is because in the short run, prices of imports rise due to the depreciation and also in the short run there is a lag in changing consumption of imports, therefore there is an immediate jump followed by a lag until the long run prevails and consumers stop importing as many expensive goods and along with the rise in exports cause the current account to increase (a smaller deficit or a bigger surplus). [1] Moreover, in the short run, demand for the more expensive imports (and demand for exports, which are cheaper to foreign buyers using foreign currencies) remain price inelastic. This is due to time lags in the consumer's search for acceptable, cheaper alternatives (which might not exist).
Over the longer term a depreciation in the exchange rate can usually be expected to improve the current account balance. Domestic consumers switch to domestic products and away from the now more expensive imported goods and services. Equally, many foreign consumers may switch to purchasing the products being exported into their country, which are now cheaper in the foreign currency, instead of their own domestically produced goods and services.
Empirical investigations of the J curve have sometimes focused on the effect of exchange rate changes on the trade ratio, i.e. exports divided by imports, rather than the trade balance, exports minus imports. Unlike the trade balance, the trade ratio can be logarithmically transformed regardless of whether a trade deficit or trade surplus exists. [2]
The asymmetric J-curve implies that there could be an asymmetric relationship between the exchange rate changes and trade balance. The asymmetric effects of real exchange rate on trade balance were initially reported by the American economist Mohsen Bahmani-Oskooee from the University of Wisconsin–Milwaukee. However, the term asymmetric J-curve was coined by the British economists Muhammad Ali Nasir and Mary Leung. They employed cumulative dynamic multiplier analysis and reported empirical evidence of an asymmetric J-curve in an article on US trade deficit. [3]
In private equity, the J curve is used to illustrate the historical tendency of private equity funds to deliver negative returns in early years and investment gains in the outlying years as the portfolios of companies mature. [4] [5]
In the early years of the fund, a number of factors contribute to negative returns including management fees, investment costs and under-performing investments that are identified early and written down. Over time the fund will begin to experience unrealized gains followed eventually by events in which gains are realized (e.g., IPOs, mergers and acquisitions, leveraged recapitalizations). [6]
Historically, the J curve effect has been more pronounced in the US, where private equity firms tend to carry their investments at the lower of market value or investment cost and have been more aggressive in writing down investments than in writing up investments. As a result, the carrying value of any investment that is underperforming will be written down but the carrying value of investments that are performing well tend to be recognized only when there is some kind of event that forces the private equity firm to mark up the investment. [7]
The steeper the positive part of the J curve, the quicker cash is returned to investors. A private equity firm that can make quick returns to investors provides investors with the opportunity to reinvest that cash elsewhere. Of course, with a tightening of credit markets, private equity firms have found it harder to sell businesses they previously invested in. Proceeds to investors have reduced. J curves have flattened dramatically. This leaves investors with less cash flow to invest elsewhere, such as in other private equity firms. The implications for private equity could well be severe. Being unable to sell businesses to generate proceeds and fees means some in the industry have predicted consolidation amongst private equity firms.[ citation needed ]
In political science, the "J curve" is part of a model developed by James Chowning Davies to explain political revolutions. Davies asserts that revolutions are a subjective response to a sudden reversal in fortunes after a long period of economic growth, which is known as relative deprivation. Relative deprivation theory claims that frustrated expectations help overcome the collective action problem, which in this case may breed revolt. Frustrated expectations could result from several factors, including growing levels of inequality within a country, which may mean those who are increasingly poor relative to the rich are getting less than they expected, or a period of sustained economic development, lifting general expectations, followed by a crisis.
This model is often applied to explain social and political unrest and efforts by governments to contain this unrest. This is referred to as the Davies' J curve, because economic development followed by a depression would be modeled as an upside down and slightly skewed J.
Another "J curve" refers to the correlation between stability and openness. This theory was suggested initially by the author Ian Bremmer, in his book The J Curve: A New Way to Understand Why Nations Rise and Fall.
The x-axis of the political J curve graph measures the 'openness' of the economy in question and the y-axis measures the stability of that same state. It suggests that those states that are 'closed'/undemocratic/unfree (such as the Communist dictatorships of North Korea and Cuba) are very stable; however, as one progresses right, along the x-axis, it is evident that stability (for relatively short period of time in the lengthy life of nations) decreases, creating a dip in the graph, until beginning to pick up again as the 'openness' of a state increases; at the other end of the graph to closed states are the open states of the West, such as the United States of America or the United Kingdom. Thus, a J-shaped curve is formed.
States can travel both forward (right) and backwards (left) along this J curve, and so stability and openness are never secure. The J is steeper on the left hand side, as it is easier for a leader in a failed state to create stability by closing the country than to build a civil society and establish accountable institutions; the curve is higher on the far right than left because states that prevail in opening their societies (Eastern Europe, for example) ultimately become more stable than authoritarian regimes.
Bremmer's entire curve can shift up or down depending on economic resources available to the government in question. So Saudi Arabia's relative stability at every point along the curve rises or falls depending on the price of oil; China's curve analogously depends on the country's economic growth.
In medicine, the "J curve" refers to a graph in which the x-axis measures either of two treatable symptoms (blood pressure or blood cholesterol level) while the y-axis measures the chance that a patient will develop cardiovascular disease (CVD). It is well known that high blood pressure or high cholesterol levels increase a patient's risk. What is less well known is that plots of large populations against CVD mortality often take the shape of a J curve which indicates that patients with very low blood pressure and/or low cholesterol levels are also at increased risk.

Balance of trade is the difference between the monetary value of a nation's exports and imports over a certain time period. Sometimes a distinction is made between a balance of trade for goods versus one for services. The balance of trade measures a flow variable of exports and imports over a given period of time. The notion of the balance of trade does not mean that exports and imports are "in balance" with each other.
The invisible balance or balance of trade on services is that part of the balance of trade that refers to services and other items that do not result in the transfer of physical objects. Examples include consulting services, shipping services, tourism, and patent license revenues. This figure is usually generated by tertiary industry. The term 'invisible balance' is especially common in the United Kingdom.

In finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro.
The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic action that together facilitate international flows of financial capital for purposes of investment and trade financing. Since emerging in the late 19th century during the first modern wave of economic globalization, its evolution is marked by the establishment of central banks, multilateral treaties, and intergovernmental organizations aimed at improving the transparency, regulation, and effectiveness of international markets. In the late 1800s, world migration and communication technology facilitated unprecedented growth in international trade and investment. At the onset of World War I, trade contracted as foreign exchange markets became paralyzed by money market illiquidity. Countries sought to defend against external shocks with protectionist policies and trade virtually halted by 1933, worsening the effects of the global Great Depression until a series of reciprocal trade agreements slowly reduced tariffs worldwide. Efforts to revamp the international monetary system after World War II improved exchange rate stability, fostering record growth in global finance.
In international economics, the balance of payments of a country is the difference between all money flowing into the country in a particular period of time and the outflow of money to the rest of the world. In other words, it is economic transactions between countries during a period of time. These financial transactions are made by individuals, firms and government bodies to compare receipts and payments arising out of trade of goods and services.
In macroeconomics and international finance, a country's current account records the value of exports and imports of both goods and services and international transfers of capital. It is one of the two components of the balance of payments, the other being the capital account. Current account measures the nation's earnings and spendings abroad and it consists of the balance of trade, net primary income or factor income and net unilateral transfers, that have taken place over a given period of time. The current account balance is one of two major measures of a country's foreign trade. A current account surplus indicates that the value of a country's net foreign assets grew over the period in question, and a current account deficit indicates that it shrank. Both government and private payments are included in the calculation. It is called the current account because goods and services are generally consumed in the current period.
The Bretton Woods system of monetary management established the rules for commercial relations among the United States, Canada, Western European countries, and Australia and other countries, a total of 44 countries after the 1944 Bretton Woods Agreement. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent states. The Bretton Woods system required countries to guarantee convertibility of their currencies into U.S. dollars to within 1% of fixed parity rates, with the dollar convertible to gold bullion for foreign governments and central banks at US$35 per troy ounce of fine gold. It also envisioned greater cooperation among countries in order to prevent future competitive devaluations, and thus established the International Monetary Fund (IMF) to monitor exchange rates and lend reserve currencies to nations with balance of payments deficits.
In macroeconomics and modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.
The Mexican peso crisis was a currency crisis sparked by the Mexican government's sudden devaluation of the peso against the U.S. dollar in December 1994, which became one of the first international financial crises ignited by capital flight.
The Marshall–Lerner condition is satisfied if the absolute sum of a country's export and import demand elasticities is greater than one. If it is satisfied, then if a country begins with a zero trade deficit then when the country's currency depreciates, its balance of trade will improve. The country's imports become more expensive and exports become cheaper due to the change in relative prices, and the Marshall-Lerner condition implies that the indirect effect on the quantity of trade will exceed the direct effect of the country having to pay a higher price for its imports and receive a lower price for its exports.
The Mundell–Fleming model, also known as the IS-LM-BoP model, is an economic model first set forth (independently) by Robert Mundell and Marcus Fleming. The model is an extension of the IS–LM model. Whereas the traditional IS-LM model deals with economy under autarky, the Mundell–Fleming model describes a small open economy.
Foreign trade of Argentina includes economic activities both within and outside Argentina especially with regards to merchandise exports and imports, as well as trade in services.
In macroeconomics, the twin deficits hypothesis or the twin deficits phenomenon, is the observation that, theoretically, there is a strong causal link between a nation's government budget balance and its current account balance.
The economic history of the Republic of Turkey had four eras or periods. The first era had the development policy emphasizing private accumulation between 1923 and 1929. The second era had the development policy emphasized state accumulation in a period of global crises between 1929 and 1945. The third era was state-guided industrialization based on import-substituting protectionism between 1950 and 1980. The final, era was the opening of the economy to liberal trade in goods, services and financial market transactions since 1981.
Revaluation is a change in a price of a good or product, or especially of a currency, in which case it is specifically an official rise of the value of the currency in relation to a foreign currency in a fixed exchange rate system. In contrast, a devaluation is an official reduction in the value of the currency. Under floating exchange rates, a rise in a currency's value is an appreciation. Altering the face value of a currency without changing its purchasing power is a redenomination, not a revaluation.
Currency depreciation is the loss of value of a country's currency with respect to one or more foreign reference currencies, typically in a floating exchange rate system in which no official currency value is maintained. Currency appreciation in the same context is an increase in the value of the currency. Short-term changes in the value of a currency are reflected in changes in the exchange rate.
A sudden stop in capital flows is defined as a sudden slowdown in private capital inflows into emerging market economies, and a corresponding sharp reversal from large current account deficits into smaller deficits or small surpluses. Sudden stops are usually followed by a sharp decrease in output, private spending and credit to the private sector, and real exchange rate depreciation. The term "sudden stop" was inspired by a banker’s comment on a paper by Rüdiger Dornbusch and Alejandro Werner about Mexico, that "it is not speed that kills, it is the sudden stop."
The 1991 Indian economic crisis was an economic crisis in India resulting from a balance of payments deficit due to excess reliance on imports and other external factors. India's economic problems started worsening in 1985 as imports swelled, leaving the country in a twin deficit: the Indian trade balance was in deficit at a time when the government was running on a huge fiscal deficit.
Fear of floating is the hesitancy of a country to follow a floating exchange rate regime, rather than a fixed exchange rate. This is more relevant in emerging economies, especially when they suffered from financial crisis in the last two decades. In foreign exchange markets of the emerging market economies, there is evidence showing that countries who claim they are floating their currency, are actually reluctant to let the nominal exchange rate fluctuate in response to macroeconomic shocks. In the literature, this is first convincingly documented by Calvo and Reinhart with "fear of floating" as the title of one of their papers in 2000. Since then, this widespread phenomenon of reluctance to adjust exchange rates in emerging markets is usually called "fear of floating". Most of the studies on "fear of floating" are closely related to literature on costs and benefits of different exchange rate regimes.
