Question

a. Distinguish between "terms of trade" and the "balance of trade.

Answer 1

terms of trade is ratio of prices of exported and imported goods,

balance of trade is difference between exports and imports, epxressed in dollars or other currency.

Answer 2

In international economics and international trade, terms of trade or TOT are the ratio of the price of an export commodity/-ies to the price of an import commodity/-ies. "Terms of trade" are sometimes used as a proxy for the relative social welfare of a country, but this heuristic is technically questionable and should be used with extreme caution. An improvement in a nation's terms of trade is good for that country in the sense that it has to pay less for the products it imports, that is, it has to give up less exports for the imports it receives.Terms of trade should not be used as synonymous with social welfare, or even Pareto economic welfare. Terms of trade calculations do not tell us about the volume of the countries' exports, only relative changes between countries. To understand how a country's social utility changes, it is necessary to consider changes in the volume of trade, changes in productivity and resource allocation, and changes in capital flows.In the real world of over 200 nations trading hundreds of thousands of products, terms of trade calculations can get very complex. Thus, the possibility of errors is significant.
The balance of trade (or net exports, NX) is the difference between the monetary value of exports and imports in an economy over a certain period of time. A positive balance of trade is known as a trade surplus and consists of exporting more than your imports; a negative 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; especially in the United Kingdom the terms visible and invisible balance are used.

The balance of trade forms part of the current account, which also 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 domestic demand (the difference between what goods a country produces and how many goods it buys from abroad, this does not include money respent on foreign stocks, nor does it factor the concept of importing goods to produce for the domestic market).

Measuring the balance of payments 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, and other visibility problems. However, especially for developed countries, accuracy is likely to be good.

Factors that can affect the balance of trade figures include:
Prices of goods manufactured at home (influenced by the responsiveness of supply)
Exchange rates
Trade agreements or barriers
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.
