ECO2103 Macroeconomics: Analysis of GDP, Inflation, Unemployment

This report provides a macroeconomic analysis based on current articles, examining GDP growth in the USA, inflation in Japan, unemployment trends in the USA, interest rate policies in Indonesia, and business cycle indicators in South Africa. The analysis uses economic models such as AD-AS, demand-supply dynamics in the labor market, and investment-interest rate relationships to explain the observed phenomena. It concludes that despite economic tensions, the US economy shows growth due to fiscal stimuli and global development, while Japan's inflation is aggravated by oil prices and monetary policies. Furthermore, job growth in the US isn't raising wages due to low-wage jobs, Indonesia is holding interest rates to stimulate growth, and South Africa shows positive growth trends with potential for future boom.

Chapter 1: Macroeconomics, GDP and Economic Growth
a. Article Title: “Amid massive Trump-induced chaos, GDP growth continues. Why?”
(Dallasnews.com 2018)
Article Source: https://www.dallasnews.com/opinion/commentary/2018/07/19/amid-
massive-trump-induced-chaos-gdp-growth-continues
b. Article Summary
According to the article, on one hand, the country can be seen to be struggling with a
possible trade war, fallacies on part of the government and political tensions and on the other
hand the GDP of the country can be seen to be showing positive and impressive growth rates
(nearly 4.5%) (Dallasnews.com 2018). The article attributes this growth in GDP to the
aspects like the increase in the development and economic activities of the economies with
which the USA enjoys economic linkages, fiscal stimuli on part of the government in the
forms of tax cuts and increased government expenditures (Jorgenson, Gollop and Fraumeni
2016).
c. Analysis:
The above phenomenon can be explained with the help of the AD-AS model. The
components of AD include consumption, investment, government expenditures and net
exports:
AD = C+I+G+NX
Due to the fiscal stimuli, G can be seen to be increasing and due to a highly profitable
financial market and robust development of partner economies, investment is also rising. The
growth of the partner nations is also contributing in higher exports, thereby increasing NX.
Along with the same, with the tax cuts, especially in the domain of businesses and corporate

expansions, the investment can also be seen to be increasing in the country, which, in turn,
can also be seen to be contributing to the increase in the AD of the country.

(Source: As created by the author)
This increase in the AD, can be seen to be increasing the GDP of the country (Heijdra
2017), as with the increase in the AD, the producers are encouraged to produce more, thereby
increasing the economic productivity of the country, which is reflected in the GDP dynamics
of the country.
Chapter 2: Inflation and rise in price levels
a. Article Title: “Japan's core inflation rate rises to 0.8% in June on energy boost”
(Asia.nikkei.com 2018)
Article Source: https://asia.nikkei.com/Economy/Japan-s-core-inflation-rate-rises-to-0.8-in-
June-on-energy-boost

4MACROECONOMIC ASSIGNMENT
b. Article Summary:
As per the assertions of the article, in the quarter of June, the CPI of Japan, rose by
nearly 0.8% (Asia.nikkei.com 2018). The main reasons behind the rise in the inflation, as per
the arguments put forward by the article, are that of increase in the price of oil and gasoline
and also on the aspects of loose monetary policies which include the policy of monetary
easing (Abhyankar, Xu and Wang 2013).
c. Analysis:
The situation prevailing in the country, in terms of the price level scenarios can be
explained with the help of the concepts of demand and supply dynamics and the same can be
expressed with the help of the diagram as follows:
Figure 2: Effects of rise in oil price and monetary easing in Japan
(Source: As created by the author)

5MACROECONOMIC ASSIGNMENT
As the above figure shows, due to the rise in oil price, the overall production level can
be seen to be falling, mainly due to the increase in the cost of production, which compels the
producers to reduce their production (Bernanke et al. 2018). However, due to the monetary
easing and loose monetary policy on part of the Japanese Government, the demand does not
seem to be negatively affected, to that extent, which in turn can be seen to have aggravated
the inflation to a greater extent, since a fall in the supply with the demand patterns remaining
the same, tend to draw the average price levels of the country upwards.
Chapter 3: Unemployment and Wages
a. Article Title: “Why Wages Won't Rise When Unemployment Falls” (Forbes.com 2018)
Article Source: https://www.forbes.com/sites/teresaghilarducci/2018/07/18/why-wages-
wont-rise-when-unemployment-falls/#56b42e635d9d
b. Article Summary:
The article contradicts the general assertion of Phillips Curve, citing the case of the
contemporary economy of the USA, where the wages are not seen to be rising with the fall in
the rate of unemployment. The primary reason attributed to the same, by the article, is that of
the rising importance of capital over labour and productivity running ahead of wages
(Coibion and Gorodnichenko 2015). The other reason pointed out by the article, is that of the
increase in the demand as well as the supply of low wage employment scopes, in the face of
the increase in the labour force in the country and the loss of the bargaining power of the
workers due to the weakening of the labour unions (Forbes.com 2018).
c. Analysis
The relation between the wage and the level of employment of labour, in the
contemporary economy of the USA, can be elaborated with economic concepts of demand-

6MACROECONOMIC ASSIGNMENT
supply situations in the labour market (Coibion and Gorodnichenko 2015). The wage being
the price of the labours, an increase in the supply of labours leads to fall in thee wages and
vice versa, which is shown as follows:
Figure 3: Demand-Supply dynamics in the USA labour market
(Source: As created by the author)
In the concerned case, due to the presence of huge labour supply in the economy of
the USA, new jobs are created which are mostly of low-wage types and the labours, in the
face of high competitions, are accepting the same, which in turn can be seen to be
contributing in sluggish growth in the wage levels in the country. The aspects of presence of
higher importance of capital over labour and the chances of substitutability of the latter by the
former also make the labours more vulnerable, thereby compelling them to resort to low paid
jobs.
Chapter 4: Financial Markets, Capital Formation and Savings
a. Article Title: “Bank Indonesia keeps interest rate on hold” (Businesstimes.com.sg 2018)

7MACROECONOMIC ASSIGNMENT
Article Source: https://www.businesstimes.com.sg/banking-finance/bank-indonesia-keeps-
interest-rate-on-hold
b. Article Summary:
According to the assertions of the concerned article, in spite of the presence of room
for increase in the rate of interest, the government of Indonesia, has resorted to keep it
constant rate of 5.25% in the current period (Rosser 2013). The primary reasons behind the
same, as highlighted by the article are the presence of harmless dynamics in the inflation
scenario of the country as well as the stagnation in the economic growth of the country to
boost which the rate of interest is not hiked further by the government.
c. Analysis:
The rate of interest in a country is inversely related to the investment volumes of the
same, as with the increase in the rate of interest, people become less eager to borrow money
for the purpose of investing, as can be seen from the following figure:
Figure 4: Investment and Rate of Interest

8MACROECONOMIC ASSIGNMENT
(Source: As created by the author)
Due to the successive rise in the rate of interest, the investments and economic
productivity of Indonesia could be seen to be hampered, as can be seen from their sluggish
economic growth. Investment being a part of the AD, the fall in the former effects the latter
negatively which in turn is expected to lead to an economic stagnating situation in the
country. To combat the same and to increase the level of investments, the rate of interest can
be seen to be keep at a constant level in the recent period (Arrow and Kruz 2013).
Chapter 5: Business Cycle, Short-term Economic Fluctuations and Aggregate
Expenditure
a. Article Title: “EXPLAINER: The business cycle and GDP” (Fin24.com 2018)
Article Source: https://www.fin24.com/Economy/explainer-the-business-cycle-and-gdp-
20180703
b. Article Summary:
Explaining the aspects of GDP and its components like consumption, government
spending, investments and also the net exports, the article asserts that in spite of the
difficulties of predicting the future situation of the economy of South Africa, the current
situation can be seen from the Business Cycle Indicator of the country, which is as follows:

9MACROECONOMIC ASSIGNMENT

(Source: Fin24.com 2018)
From the above figure, the article asserts that there are possibilities of upward patterns
in the business cycle of the economy in the future years (Fedderke 2014).
c. Analysis
The “Business Cycle” of an economy, showing the fluctuations in its growth patterns,
is generally dependent on the economic fluctuations in a country and can be seen to be
generally of the following nature:

10MACROECONOMIC ASSIGNMENT
Figure 6: Business Cycle
(Source: As created by the author)
The upward rise till the peak indicates towards positive economic growth and a period
of high productivity and boom while the downward dynamics and trough highlight the
presence of economic stagnation and recessionary situations (Gilchrist and Zakrajšek 2012).
Thus, from the situation of the economy of South Africa, it can be assumed that the economy
of the country is in the path of high productivity and can experience further positive growth
in the business cycle in the coming years. That is in the coming years, the country is expected
to be on the upper (high productivity and boom) area of the business cycle.
Conclusion
From the above discussion, it can thus be asserted, that in spite of the economic
tensions, the economy of the USA can be seen to be increasing due to its own fiscal stimuli as
well as development of the partner countries. The inflation in Japan, can however be seen to
be aggravated by the rise in the oil prices as well as loose monetary policies in the country.

11MACROECONOMIC ASSIGNMENT
The increase in the employment in the USA, however, cannot be seen to be rising the wages
as most of the jobs created are of low-wage types. To stimulate the stagnated economic
growth of Indonesia, the Central Bank can be seen to stall the hike in the rate of interest in the
recent periods. South African economy, however, can be seen to be showing positive growth
trends, with future prospects of boom in its business cycle if the trend of economic growth
continues.
