When this number is falling, the country is said to have "deteriorating terms of trade". Krugman Terms of trade changes on welfare that rapid developing country does not necessarily experience a deteriorating terms of trade process, and they can avoid the drop of relative prices through commodity diversification [2].

The Export Relies Strongly in a Limited Range of Primary Products Firstly, the primary products account a small proportion of the export in China and the proportion is dropping year by year from Time series diagram and time trend line were obtained using the R statistical environment R Development Core Team, For example, countries that export oil will see an increase in their TOT when oil prices go up, while the TOT of countries that import oil would decrease.

The Effect of Terms of Trade Changes on Welfare in Iceland

In this case the imports of one country are the exports of the other country. The terms of trade measures the rate of exchange of one good or service for another when two countries trade with each other.

The development mode of trade in China is more like that in Germany and Japan, which is moving forward to the high-tech products with high price elasticity of demand. Although the real GDP is deemed as a measured index of wealth for a country, the author has introduced the concept of GDI Gross Domestic Income under the SNA accounting framework to take the terms of trade into consideration [10,11].

Therefore the real GDP and export is still the least correlated, i. The FDI in exports and imports account for a large proportion in trade in China and the cheap labor forces is the main reason that attracts the FDI. That is to say, there were more and more exported manufactured goods in China, therefore the export price index should go up.

Terms of Trade Effects: This is shown in Table 1. However it was not the case.

According to the result, there are only On the contrary, the proportion of manufactured goods increases constantly from On the other hand, with petroleum prices excluded, US terms of trade begin to improve steadily starting in and the relative price of tradables falls. Thus GDI is given by: As a result, the increase in import price index was far more than that in export price index and that lead to the downturn in terms of trade.

We have illustrated the former part with different data and statistics, and we will analyze the later part of the states to check out whether the real income level and consumption level go down.

They export the products processed with the imported raw materials and make China the price taker. The exports of high-tech products rise year by year from Although the probability of the correlation coefficient of the three variables is approachable to 0 and they are linear correlation to the GDP when the level of significance is set as 0.

Therefore, the author holds the idea that the reduce of exported products index, which leads to the declines of terms of trade, is due to the exports of processing products with low price elasticity of demand.

Theory and Methods of Measurement PDF Foreign trade enables a nation to consume a different mix of goods and services than it produces, so to measure real gross domestic income GDI for an open economy, we must deflate by an index of the prices of the things that this income is used to buy, not the price index for GDP.

And an increasing secular trend was observed in processing trade since For a short term, the mid-and-low end products take up a large percentage in exports in China, which is not prominent. In this case, the annual growth of GDP would have been Therefore, if I apply this formula for Iceland, I obtain: The terms of trade improved continuously.

This paper also presents the change of national wealth by using the weak axiom of revealed preference theory. Therefore the wealth loss brought by the decline of terms of trade was not strong enough to Figure 2.

For example, if an economy is only exporting apples and only importing oranges, then the terms of trade are simply the price of apples divided by the price of oranges — in other words, how many oranges can be obtained for a unit of apples.

The foreign investors put the end-value products into China to reduce the price of exports. Amounts are expressed in the national currency, i.

Xu and Sui et al. The author has studies the relationship between exports and real GDP with Pearson relevant and partial correlation analysis method in China in different years and also has the correlation test for consumption, investment and exports.

Quantitative Index, Revealed Preference and Consumer Welfare b is for the base period, the price level is atand the choice of the consumers is ; while at period t, the price level is atand the choice of consumers is. The speed of the wealth loss slowed down after while we were still in a loss.

Introduction China has benefited a lot from the economy globalization with the international trade as an important promoting tool.

Terms of Trade Effects: Theory and Methods of Measurement

Fisher indexes are a natural way to estimate the conceptual economic indexes of trading gains and real GDI because they are averages of the theoretical upper and lower bounds of the economic indexes. Since economies typically export and import many goods, measuring the TOT requires defining price indices for exported and imported goods and comparing the two.From toterms of trade changes had a negative and rather small effect on welfare in Iceland.

For this covered period, the average yearly percentage growth of Iceland’s terms of trade was %. 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.
