Balance of trade
The balance of trade (or net exports, sometimes symbolized as NX) is the difference between the monetary value of exports and imports of output in an economy over a certain period. It is the relationship between a nation's imports and exports. A favourable balance of trade is known as a trade surplus and consists of exporting more than is imported; an unfavourable balance of trade is known as a trade deficit or, informally, a trade gap. The balance of trade is sometimes divided into a goods and a services balance.
DefinitionThe balance of trade forms part of the current account, which includes other transactions such as income from the international investment position as well as international aid. If the current account is in surplus, the country's net international asset position increases correspondingly. Equally, a deficit decreases the net international asset position.
The trade balance is identical to the difference between a country's output and its domestic demand (the difference between what goods a country produces and how many goods it buys from abroad; this does not include money re-spent on foreign stocks, nor does it factor the concept of importing goods to produce for the domestic market).
Measuring the balance of trade can be problematic because of problems with recording and collecting data. As an illustration of this problem, when official data for all the world's countries are added up, exports exceed imports by a few percent; it appears the world is running a positive balance of trade with itself. This cannot be true, because all transactions involve an equal credit or debit in the account of each nation. The discrepancy is widely believed to be explained by transactions intended to launder money or evade taxes, smuggling and other visibility problems. However, especially for developed countries, accuracy is likely.
Factors that can affect the balance of trade figures include:
Prices of goods manufactured at home (influenced by the responsiveness of supply)
Exchange rates regarded in 1933
Trade agreements or barriers
Offset agreements
Other tax, tariff and trade measures
Business cycle at home or abroad.
The balance of trade is likely to differ across the business cycle. In export led growth (such as oil and early industrial goods), the balance of trade will improve during an economic expansion. However, with domestic demand led growth (as in the United States and Australia) the trade balance will worsen at the same stage in the business cycle.
Since the mid 1980s, United States has had a growing deficit in tradeable goods, especially with Asian nations (China and Japan) which now hold large sums of U.S debt that has funded the consumption. The U.S. has a trade surplus with nations such as Australia and Canada. The issue of trade deficits can be complex. Trade deficits generated in tradeable goods such as manufactured goods or software may impact domestic employment to different degrees than trade deficits in raw materials.
Economies such as Canada, Japan, and Germany which have savings surpluses, typically run trade surpluses. China, a high growth economy, has tended to run trade surpluses. A higher savings rate generally corresponds to a trade surplus. Correspondingly, the United States with its lower savings rate has tended to run high trade deficits, especially with Asian nations.
Views on economic impactEconomists are sometimes divided on the economic impact of the trade deficit.
Conditions where trade deficits may be considered harmful
Balance of tradeThose who ignore the effects of long run trade deficits may be confusing David Ricardo's principle of comparative advantage with Adam Smith's principle of absolute advantage, specifically ignoring that latter. The economist Paul Craig Roberts notes that the comparative advantage principles developed by David Ricardo do not hold where the factors of production are internationally mobile. Global labor arbitrage, a phenomenon described by economist Stephen S. Roach, where one country exploits the cheap labor of another, would be a case of absolute advantage that is not mutually beneficial.
Detiorating U.S. net international investment position (NIIP) has caused concern among economists over the effects of outsourcing and high U.S. trade deficits over the long-run.Since the stagflation of the 1970s, the U.S. economy has been characterized by slower GDP growth. In 1985, the U.S. began its growing trade deficit with China. Over the long run, nations with trade surpluses tend also to have a savings surplus while the U.S. has been plagued by persistently lower savings rates than its trading partners which tend to have trade surpluses with the U.S. Germany, France, Japan, and Canada have maintained higher savings rates than the U.S. over the long run. Some economists believe that GDP and employment can be dragged down by an over-large deficit over the long run. Wealth-producing primary sector jobs in the U.S. such as those in manufacturing and computer software have often been replaced by much lower paying wealth-consuming jobs such those in retail and government in the service sector when the economy recovered from recessions. Some economists contend that the U.S. is borrowing to fund consumption of imports while accumulatiing unsustainable amounts of debt.
In 2006, the primary economic concerns centered around: high national debt ($9 trillion), high non-bank corporate debt ($9 trillion), high mortgage debt ($9 trillion), high financial institution debt ($12 trillion), high unfunded Medicare liability ($30 trillion), high unfunded Social Security liability ($12 trillion), high external debt (amount owed to foreign lenders) and a serious deterioration in the United States net international investment position (NIIP) (-24% of GDP), high trade deficits, and a rise in illegal immigration.
These issues have raised concerns among economists and unfunded liabilities were mentioned as a serious problem facing the United States in the President's 2006 State of the Union address. On June 26 2009, Jeff Immelt, the CEO of General Electric, called for the United States to increase its manufacturing base employment to 20% of the workforce, commenting that the U.S. has outsourced too much in some areas and can no longer rely on the financial sector and consumer spending to drive demand.
Conditions where trade deficits may not be harmful
When economists contend trade deficits are not harmful, they generally refer to explanations of comparative advantage. Buyers in the receiving country send the money back. A firm in America sends dollars for Brazilian sugarcane, and the Brazilian receivers use the money to buy stock in an American company. This may lead to profits leaving the U.S however as Americans may forfeit control. Although this is a form of capital account reinvestment, it may not be a liability on anyone in America.
Such payments to foreigners have intergenerational effects: by shifting the consumption schedule over time, some generations may gain and others lose . However, a trade deficit may incur consumption in the future if it is financed by profitable domestic investment, in excess of that paid on the net foreign debts. Similarly, an excess on the current account shifts consumption to future generations, unless it raises the value of the currency, detering foreign investment.
However, trade inequalities are not natural given differences in productivity and consumption preferences. Trade deficits have often been associated with international competitiveness. Trade surpluses have been associated with policies that skew a country's activity towards externalities, resulting in lower standards. An example of an economy which has had a positive balance of trade was Japan in the 1990s.
Milton Friedman argued that trade deficits are not necessarily important as high exports raise the value of the currency, reducing aforementioned exports, and vise versa for imports, thus naturally removing trade deficits not due to investment. Milton Friedman's son, David D. Friedman, shares this view and cites the comparative advantage concepts of David Ricardo.
