## 经济代写|宏观经济学作业代写Macroeconomics代考|WHAT IS MACROECONOMICS

Macroeconomics studies the economy of a country or region from a broad perspective without considering too many details about a specific sector or business. Macroeconomists study changes in the aggregate, collecting data on the level of production, unemployment, inflation, consumption, investment, trade, and the current account, and other aspects of national and international economic life. Policymakers depend on macroeconomists’ knowledge of the main elements and basic forces that govern each country’s economy and the global economy when making decisions about taxes, industry regulations, trade policies, and more. These analyses affect decisions made by individuals and businesses, especially in a globalized world.

This branch of economics attempts to answer fundamental questions such as the following

• Why does a country become richer or poorer in a certain period? For example, what explains the sustained high growth rates of the Asian tigers (Hong Kong, Singapore, South Korea, and Taiwan) between the early 1960 s and the 1990 s, and China’s high growth rates after 1978 ? Why was South Korea poorer than the Latin American countries in the early 1960 s yet today has three times the average Latin American income? Why has the Democratic Republic of Congo, one of the poorest countries in the world, had an average annual drop of more than 3 percent in its per capita income over the last thirty years?
• What causes unemployment? Why is there such a great difference among countries’ unemployment rates? There is evidence for widely ranging unemployment rates even within the euro zone: $4.3$ percent in Germany and $19.4$ percent in Spain in 2016. Furthermore, what causes the unemployment rate to fluctuate greatly within a single country during a short period of time? In Brazil, for example, the rate was 12 percent in 2004 ; it fell to 7 percent in 2011 and returned to a double-digit rate of 11 percent in $2016 .$

The most important measurement of an economy is the gross domestic product (GDP), a statistical indicator that tries to measure the total value of the goods and services produced within the geographic limits of a country or region during a specific period. It is calculated by aggregating the market values of all the final goods and services produced in an economy, that is, excluding intermediate inputs used in the production process (e.g., the value of roofing nails would be counted as part of the value of a new roof, not when the contractor or roofer buys the nails in order to start the project. An individual’s purchase of roofing nails at a hardware store for personal use, however, would be counted directly in the GDP). Because the value of goods and services is determined by the prices paid by consumers and businesses, the GDP can also be understood as a measure of a given country’s income over a particular period of time.

The United States contributes about 25 percent of world output, while the seven main developed economies(the United States, Japan, Germany, the UK, France, Italy, and Canada) together contribute around 49 percent (table 1). In this context, the Asian giants (China and India) have been gaining importance on the world stage: in 2017 they represented 19 percent of world GDP, whereas eight years ago they accounted for only 9 percent. On the other hand, Latin America and the Caribbean contribute 8 percent to global GDP.

## 经济代写|宏观经济学作业代写Macroeconomics代考|Economists differentiate

Economists differentiate between two types of GDP: nominal and real. Nominal GDP measures the value of goods and services according to their current market price. Real GDP measures the physical volume of production for a given period using the prices of a base year.

Note that if the prices of all goods double but physical production remains constant, the measure of nominal GDP doubles, while real GDP remains the same. This is because price variations do not affect physical production.
Also note that although GDP growth may be positive over a long period, it may also show rises and falls over a shorter period. Such short-term fluctuations (expansions and contractions) in the economy are known as business or economic cycles. The moment of maximum output expansion within a cycle is referred to as its peak, while the lowest point is referred to as its trough. A complete economic cycle is measured from one trough to the next (figure 1).

When GDP is rising, the economy is said to be expanding, and when GDP is falling, the economy is said to be contracting. A contraction is signaled by the fall from a peak to a trough; an expansion is the rise from a trough to a peak.

• 为什么一个国家会在某个时期变得更富或更穷？例如，如何解释亚洲四小龙（香港、新加坡、韩国和台湾）在 1960 年代初至 1990 年代之间的持续高增长率，以及 1978 年后中国的高增长率？为什么韩国在 1960 年代初期比拉丁美洲国家更穷，而今天却是拉丁美洲平均收入的三倍？为什么刚果民主共和国是世界上最贫穷的国家之一，其人均收入在过去 30 年平均每年下降 3% 以上？
• 什么导致失业？为什么各国的失业率差异如此之大？有证据表明即使在欧元区内也存在广泛的失业率：4.3在德国和19.42016 年西班牙的百分比。此外，是什么导致失业率在短时间内在单个国家内大幅波动？例如，在巴西，2004 年的比率为 12%；2011 年下降到 7%，并在 2011 年恢复到 11% 的两位数。2016.
