Will ‘Abenomics’ Save the Japanese Economy?

PDF File: “Will ‘Abenomics’ Save the Japanese Economy?” by Kim Sang Keun

I. Introduction

Ever since Shinzo Abe came to power, the Japanese government led by LDP has vowed to revive the stagnant economy by implementing bold economic policies. In effort to overcome so-called ‘Lost Decades,’ which has deteriorated the ego of many Japanese people, Abe has announced three simple economic policies that earned the name ‘Abenomics’ after its proposer. This includes indefinite quantitative easing, flexible public finance policy and economic growth strategy.[8] In this paper, we will look at the economic logic behind the Abenomics and problems and risks associated with it.

II. Economic Logic Behind Abenomics

Through Abenomics, the Japanese government hopes to revive its economy by implementing bold, powerful economic policies that will pull its economy out of deflation, depreciate Japanese yen, and induce CPI inflation rate of 2% per year. The Japanese government saw the constant decline of overall price level by lack of aggregate demand as the main culprit of the long-term recession that its country was going through.[3] In order to ‘reflate’ its economy, Abenomics tries to implement quantitative easing, fiscal policy through expanding government spending, and provide economic growth strategy. We will first look at the quantitative easing and its economic theory behind what the Abenomics is trying to achieve.

For analyzing the economic theory of Abenomics, the Mundell-Fleming Model for a large open economy was used in this paper as the main model. The following are the IS-LM equations for the model:

IS: Y = C(Y-T) + I(r) + G + NX(e)

LM: M/P = L(r,Y)

Notice that the assumption of r = r* was dropped, which is an equation for a small economy that cannot influence the world interest rate. As Japan is the third largest economy in the world, the assumption that it has little influence on the world financial market had to be dropped. Therefore, the interest rate was treated as an endogenous variable. As a result, LM curve got a positive slope, instead of being vertical.



First of all, the Bank of Japan is targeting a 2% CPI inflation rate and increasing the money supply circulating in the economy by buying various financial assets such as the government bond, which is essentially monetary expansion policy.[3] It could be said that this indefinite quantitative easing is the core of Abenomics. On the graph above, the increase in the money supply shifts the LM curve to the right, raising the income from Y1 to Y2, and lowering the real interest rate from r1 to r2. The decrease in the real interest rate then increases the net capital outflow as is illustrated on the second graph.


As the net capital outflow increases from CF1 to CF2, the supply of Japanese yen in the market for foreign exchange increases. The exchange rate falls from e1 to e2, depreciating the Japanese yen. This makes the Japanese goods relatively cheaper to foreign goods and the net export rises from NX1 to NX2. There are two channels for this mechanism. First, as the monetary expansion lowers the interest rate, this stimulates the investment. Second, as the monetary policy causes the currency to depreciate in the market for foreign exchange, this stimulates net exports.


All in all, the Abenomics tries to devaluate its allegedly over-appreciated yen and cause an inflation rate of 2% as the output increases. As a result, the Japanese yen has depreciated until the 103.42 (JPY/USD) recently on May 22nd. This is the lowest in almost 6 years, ever since the Global Financial Crisis that hit the economy around the world in 2007. This is shown in the exchange rate graph above.



Secondly, the Japanese government is trying to initiate fiscal policy by expanding government expenditures. As the government implements fiscal expansionary policies the IS curve shifts to the right. As the graph above illustrates, this shift in the IS curve leads to an increase in the level of income from Y1 to Y2 and an increase in the interest rate from r1 to r2. The increase in the real interest rate reduces the net capital outflow from CF1 to CF2.


As the net capital flow falls, the supply of Japanese yen in the market for foreign exchange falls. This induces the exchange rate to appreciate from e1 to e2, which decreases the net export from NX1 to NX2 as the Japanese goods become more expensive relative to foreign goods.

As the graph illustrates, the fiscal expansion by Abenomics will raise the income and output for the Japanese economy. However, it is to be pointed out that although implementing both the fiscal and monetary expansionary policies will increase the output of the Japanese economy, the effect on the exchange rate is conflicting. Yet, this problem is accounted for as the Japanese government will set its ‘desirable’ exchange rate, possibly above 100 JPY/USD, and fix it so that other variables can freely adjust, although it might compromise some of the output to some degree. Or if the Japanese government considers the increase in the economic output, and therefore the inflation rate, more important over the exchange rate, it might decide to compromise fixating the exchange rate to their ‘desired’ level for the economic growth.

Thirdly, on June 5th, the Japanese government announced the third policy for Abenomics, which includes economic growth strategy. The government announced plans for bringing up the financial integrity of Japan, however, there were no significant policies that were announced.

III. Problems and Risks Associated with Abenomics



There is a rising skepticism towards whether Abenomics would really revitalize the Japanese economy as the exchange rate appreciated breaking the 100 JPY/USD boundary and as Nikkei Index crashed. Although, theoretically, Abenomics has a sound Keynesian background, many are pointing out the fact that it is too focused on the demand side of its economy, not on the supply side.


Japanese Demography Data[11]

One of the fundamental problems that Japan is facing is its ageing population. As the population pyramid gets inverted, the labor population is shrinking every year. This brings about number of problems for the Japanese economy. First, the government commitment in spending on pensions, medical expenses and social security will continually act as a substantial burden to the already indebted country with a public debt of 240% its GDP.[11] This will further worsen the financial integrity of the Japanese government leading to an erosion of international confidence in Japanese economy. The lack of confidence can raise the risk premium (CDS) shifting the IS* curve to the left and LM* curve to the right, as θ increases for r = r* + θ. But, the exchange rate would depreciate more than what is desired by the Japanese economy, and it would force the Bank of Japan to decrease the money supply in order to bring up the yen value, shifting the LM* curve back to the left. This would aggravate the situation and lower the total income in the Japanese economy. This then would induce the interest rates to depress the prices of financial assets, which will then reduce the collateral being used as bank loans. As a result, this will lead to financial problems for Japan, further exacerbating the problems. Secondly, its dwindling workforce cannot sustain the economic output level that is maintained in the future.[11] As it is shown on the data, the demography will drastically change so that more young people will have to support for the older population, which implies that this change in demography is the main culprit for the last two decades of deflation and stagnant economic growth.[11] This has another implication to why the consumer demand might be falling behind.

In this sense, it could be said that Abenomics is failing to address the core problem of its economy. It must ask why consumer demand is inherently weak. Another major reason why the Japanese economy is stagnating is the poor productivity. This may sound strange to many people as Japan was once praised as technologically advanced country. However, according to the statistic, Japanese productivity lags badly behind world’s leading countries in many areas. For example, it lags 30% behind the U.S. in manufacturing with automobiles industry in exception.[9] Therefore, corporate reforms are needed in order to let inefficient firms downsize or die and be replaced to better ones.[9] In the case of Korea, as it suffered trough the so-called IMF Crisis in 1997, it underwent painstaking corporate reforms to let the inefficient firms die and raise the overall competitiveness of its economy. So it is doing relatively fine in terms of corporate competitiveness and financial integrity compared to Japan, although this is shaking a little due to Abenomics.

What is problematic right now is that the third policy for Abenomics lacks fundamental and specific content, which started to give erode out public confidence in Abenomics. As it was mentioned, this resulted in the crash of Nikkei Index and the re-appreciation of Japanese yen, breaking the 100 JPY/USD boundary. Shinzo Abe, afraid of losing the votes, has put aside the painstaking reforms to later, such as corporate tax cuts that will improve the productivity of Japanese firms. There was a discussion within the Japanese government in cutting the corporate taxes from 30% to 20% and to implement new policies that will make the labor market flexible.[5] However, flexible labor policy means temporary job losses[11], and it seems that Shinzo Abe is putting these essential reforms after the Japanese upper house elections. This could erode out confidence in Abenomics losing its force towards reviving the economy.

There is another risk associated with Abenomics. As the yen depreciates, net export increases as domestic products gets cheaper abroad, however, imports get more expensive. This is a big problem for Japan as ever since the Fukushima nuclear disaster, the word ‘energy crisis’ was lingering around the Japanese newspapers for two years. As Japanese public refused to use nuclear power, the Japanese government had to turn to more expensive imported energy, such as LPG, oil and naphtha, increasing the monthly value of Japanese energy imports from 1.4 trillion yen to 2.2 trillion yen.[12] This could deteriorate the competitiveness of Japanese companies, as energy prices go up. In addition, export accounts for only about 14% of its economy.[1] So the core of Abenomics should be in order to revive the domestic economy, not through export. The increase in energy prices could raise the domestic consumer prices without actually improving the income of the Japanese firms and consumers. Therefore, there is a risk towards Abenomics in that expensive energy imports will drag the Japanese economy into another lost decade.

IV. Conclusion

In conclusion, Abenomics is a sound Keynesian policy that could save the Japanese economy from deflation. The Mundell-Fleming Model was used to illustrate the economic theory behind Abenomics. However, there were considerable risks associated with Abenomics, such as the ageing population, poor productivity and the energy crisis. The key to success for Abenomics would be dependent on whether the Japanese government effectively manages these risks and confronts the fundamental reforms that would improve the supply side of its economy.

Is Abenomics Coming to a Halt?


Abe Shinzo, the Japanese Prime Minister, advocates yen devaluation

Wall Street Journal: Abenomics Will Be Felt Beyond Yen

Hankook Ilbo(Korean): 아베노믹스 ‘거꾸로 효과'(Abenomics ‘Reverse Effect’)

Abe Shinzo had explicitly announced that he would artificially devalue yen in the hope that this will help its export-dependent economy. His idea was that devaluation of yen against other currencies, especially USD, would improve price competitiveness of Japanese products overseas. This announcement was quickly criticized by many nations dependent on export such as Korea and Germany.

The Japanese government said that it would pump ‘infinite’ amount of money supply in the economy until it reaches its target inflation rate of 2%, thus achieving the devaluation of yen. Wall Street Journal expected that the inflation rate would make it less attractive for Japanese households to save and invest their money else where or simply use them to go on shopping. “Deutsche Bank said in a note Wednesday, spurring a “meaningful reallocation” of these deposits into offshore assets.” Therefore, Abe’s policy should have helped to vitalize the consumer sector of Japanese economy and at the same time increase its export to foreign countries.

However, Hankook Ilbo, a Korean newspaper, has published an article that Abe’s devaluation of yen is actually having a reverse effect on Japanese economy. According to the report published by Japanese Ministry of Finance in February 20th, 2013, exports decreased 9.4% compared to the previous month, while imports increased 8.2%. This resulted in 1.63 trillion yen deficit.

The newspaper analyzed that the main reason for this deficit is the rising prices for the energy imports due to the yen devaluation. The nation has been importing more of energy supplies such as LNG, oil, and naphtha, as it tried to diversify energy usage and reduce nuclear power following the Fukushima Nuclear Accident. According to Hankook Ilbo, “If Japanese firms fail to significantly recover from this deficit, Abenomics will be hit hard.”

In addition, many Japanese firms are showing their reluctance in raising wages for workers, which is very important for Abenomics to work in order to revive the real economy. They believe that devaluation alone will not simply rejuvenate the economy. Many Japanese companies have been outsourcing their factories overseas and it would be very hard to retrieve all those back to Japan in very short period.

Of course, it has only been several months, so it will be hard to tell whether Abe’s yen devaluation is doing well for the Japanese economy. But, I think that, from reading these articles, it would be better off for a Japanese economy to appreciate yen due to significant the increase in the energy import. The devaluation certainly is doing no good for Japanese economy and disturbing other export-driven economies such as Korea, Germany and etc.

US vs. China – Currency Dispute

New York Times: Click Here

BBC News: Click Here

According to New York Times, the Obama administration is pressuring China to stop the devaluation of yuan, a policy that fuels its persistent trade gap with the United States.

Obama administration claims that China is artificially manipulating its currency to boost up its export to US. However, Chinese premier Wen Jiabao has denied that its currency is artificially devaluated.

Why are United States and China growling at each other for this issue? It is all about trade: Export and Import.

As many of you know, China is one of the biggest exporters. You may at least have a random product that is made from China. China gets all the ‘income’ or money from exporting its goods to other foreign countries, especially United States. So it is important for China to have yuan to USD exchange rate lower in order to export a lot of their stuffs to United States. It makes their products cheaper, so they gain a great price advantage over United States.

In United States point of view, this could be disturbing to them. Obama administration has promised to make like 2 million job places for its people. However, excessive import from China is one obstacle to their economic recovery. Also, United States have lots of exporting companies that are losing the price competition to Chinese exporting companies. So, Obama administration is pressuring China to raise their exchange rate. Obama administration also fears that China is stealing American jobs.

As for China, there is no way that they are going to reevaluate their currency even if they are artificially manipulating it. The export is the main steam engine of China’s economic development so it will most unlikely give up on the low yuan. For United States, their ‘precious’ money goes into Chinese government’s pocket, which they think it should be used in order to recover their economy. They are importing more than what they are exporting to China.

In conclusion, I don’t think China will ever reevaluate its currency even if they are actually manipulating it. This dispute is just aggravating the US-Chinese relationship.
