The Tashguzar–Baysun–Kumkurgan (TBK) railway connection, completed in 2007 in southern Uzbekistan, provided a domestic through line to link rail stretches formerly connected only via neighboring Turkmenistan. We hypothesize that a better integrated domestic rail system would yield economic spillovers beyond the regions actually traversed by the new connector to generate higher growth for neighboring regions and even for the far terminal reaches of the system. We test for this using a difference in difference approach that assesses the impact of the rail connector on economic performance for each of three regional groupings relative to a control group of unaffected regions. We further distinguish effects for the short term (2008), medium term (2009–10), and long term (2011–12). We find statistically significant increases in GDP growth for all three regional groupings at medium or long term horizons with magnitudes of increase up to 2.6 percentage points per year.

Decline of oil prices and the negative interest rate policy in Japan

In April 2013, the Bank of Japan (BOJ) introduced an inflation target of 2% with the aim of overcoming deflation and achieving sustainable economic growth. But due to lower international oil prices it was unable to achieve this target and was forced to take further measures. Hence, in February 2016, the BOJ adopted a negative interest rate policy by massively increasing the money supply through the purchase of long-term Japanese government bonds (JGB). The BOJ had previously only purchased short-term government bonds, a policy that flattened the yield curve of JGBs. On the one hand, banks reduced the number of government bonds they purchased because short-term bond yields had become negative. The interest rates of long-term government bond up to 15 years even became negative. On the other hand, bank loans to corporates did not increase, due to Japanese economy's vertical investment-saving (IS) curve. The purpose of this paper is to show that the monetary policy through implementation of the zero interest rate and more recently through the negative interest rate could not help the Japanese economy to recover from the long-lasting recession and these are not the remedy. It is of key importance to make the IS curve downward rather than vertical. That means the rate of return on investment must be positive and companies must be willing to invest even if interest rates are set too low. Japan's long-term recession is due to structural problems that cannot be solved by its current monetary policy. The paper also explains why the BOJ has to reduce its 2% inflation target in the present low oil price era.

© 2017, Duncker und Humblot GmbH. All rights reserved. In April 2013, the Bank of Japan (BOJ), in order to overcome deflation and achieve sustainable economic growth, introduced an inflation target of 2 %. However due to the lower oil prices in the global market, this target could not be achieved for a long-term period. In Feb 2016, the BOJ took further steps, and started a negative interest rate policy, by increasing massive money supply through purchasing long-term Japanese government bonds (JGB). Previously the BOJ only purchased short-term government bonds. This policy has flattened the yield curve of JGBs. Banks started to reduce purchasing government bonds, because the yield of short-term government bonds’ became negative, and even for long-term government bonds up to 15 years the interest rates became negative. On the other hand, bank loans to the corporate sector did not grow, due to the vertical investment-saving (IS) curve in the Japanese economy. This paper discusses that first, in the low oil price era, the BOJ has to modify the inflation target of 2 % and reduce it, secondly it argues that the role of monetary policy and the negative interest rate policy in Japan cannot recover from the current recession and deflation situation for the long term. What is important is to make the IS curve downward sloping rather than vertical. That means the rate of return on investment must be positive and companies must be willing to invest if interest rates were set too low. The recession in Japan is coming from structural problems that cannot be solved by the current monetary policy. The last section reports a simulation results of tackling aging population of Japan by introducing productivity based wage rate and postpone retirement age will help the recovery of Japanese economy.

Small and Medium-sized enterprises are the backbone of the Asian economy. They make up more than 98% of all Asian businesses that provide two out of three private sector jobs in the continent. Therefore, it is vitally important for the Asian's economic success that has fully functioning support measures for SMEs. However, SMEs face challenges from limited access to finance, lack of a database to low R&D expenditures, undeveloped sales channels, and low level of financial inclusion are some of the reasons behind the slow growth of SMEs. This paper focuses on four major reasons that slowed the SME growth in Asia including (i) Lack of finance (ii) Lack of comprehensive database, (iii) Low level of R&D expenditures and (iv) Insufficient usage of Information technology and provides remedies for mitigating them. It is important for the Asian policymakers to implement these remedies in order to promote the production and employment in the SME sector which is the essential part of the Asian economies and is in the supply chain of large enterprises as well.

為替制度の移行における動学的な最適経路：中国，シンガポール，マレーシアの分析

吉野直行, 阿曽沼多聞

国際経済（日本国際経済学会） 68 31 - 52 2017年

共著

<p>本稿では中国・シンガポール・マレーシアにおける為替制度の最適な移行について議論する。中国は現在，ドルペッグ制を採用しているが，今後，どのような形でバスケットペッグ制または変動相場制といった望ましい為替制度に移行するのが良いか。そして中国が為替制度を徐々に変更していく場合に，シンガポールやマレーシアはどのように為替制度を変更していけばよいか。この二つの問いに答えるために，本稿は小国開放経済を想定し動学的確率的一般均衡モデル（DSGE）を用い厚生関数（損失関数）で評価をする。その中で，現行制度からバスケットペッグ制または変動相場制への移行について複数の移行策を検討する。中国にとっては経済成長（GDPの成長）を安定化させるためにはバスケットペッグ制への漸進的な移行が最適な移行経路となる。シンガポールとマレーシアも徐々に為替制度を移行してバスケット通貨制とすることが，もっとも経済成長を安定化させる結果になることが示された。 </p>

Finding stability in a time of prolonged crisis: Unconventional policy rules for Japan

Paul D. McNelis, Naoyuki Yoshino

This paper develops and estimates a dynamic stochastic general equilibrium (DSGE) model representing several key characteristics of Japan, namely, a large open economy, with large fiscal deficits and increasing amounts of debt held by domestic residents, through recurring sets of adverse shocks to productivity and positiye shocks to government spending.
We compare optimal simple rules for consumption tax rates, a Taylor rule with negative interest rates, and a quantitative easing rule, for reducing government debt held by the banking system, as well as optimizing welfare. In times of crisis, we show that the QE policy rule outperforms optimally -derived simple tax-rate rules or Taylor rules with negative interest rates for mitigating the costs of post -crisis adjustment and debt overhang.

Monetary Policy, Oil Prices and the Real Macroeconomic Variables: An Empirical Survey on China, Japan and the United States

Farhad Taghizadeh-Hesary, Naoyuki Yoshino

CHINA-AN INTERNATIONAL JOURNAL （NUS PRESS PTE LTD） 14 （ 4 ） 46 - 69 2016年11月

This article examines the impact of US monetary policy as the world dominant monetary policy on the global crude oil prices and investigates the impact of oil price fluctuations on two real macro variables (gross domestic product [GDP] and inflation rate) of three global major crude oil consumers: the People's Republic of China (an emerging economy), and Japan and the United States (developed economies). To assess the relationship between monetary variables, crude oil prices and macro variables, the authors adopt an N-variable structural vector autoregression (SVAR) model. The results suggest that the monetary policy had a significant positive impact on oil prices during 2001-13 through two different channels (quantitative easing and exchange rate fluctuations). Also, the impact of oil price fluctuations on developed oil importers' GDP growth is much milder than on the GDP growth of an emerging economy. However, the impact on the China's inflation rate is found to be less severe compared to the two developed countries.

Exchange rate regime switching in Malaysia and Singapore in response to China's move to a basket peg: A DSGE analysis

Motivated by the observation that when China broke from its US dollar peg in 2005, Malaysia and Singapore likewise loosened their currency ties to the US dollar, this paper considers how these two countries might best respond to a hypothetical transition by China to a new basket peg regime. We specify five alternative exchange rate strategies that encompass fixed, basket, and floating regimes and gradual versus sudden transitions. To project outcomes for macroeconomic variables under these alternative regimes, we apply a dynamic stochastic general equilibrium (DSGE) model of a small open economy and incorporate exogenous shocks as actually occurred from 2005 Q1 to 2014 Q4. We then compare the strategies based on values of a cumulative loss function defined on the output gap, the inflation rate, and the real effective exchange rate. The exercise reveals that a gradual adjustment to a basket peg with long-term optimal weights is the first-best policy for both countries, where optimal weights are derived to minimize the loss function. Further, both a sudden shift to a basket peg with optimal weights and a sudden shift to a floating rate regime are superior to maintaining the dollar peg in Malaysia, but not to maintaining the existing basket peg in Singapore.

Dynamic effects of changes in the exchange rate system

Naoyuki Yoshino, Sahoko Kaji, Tamon Asonuma

Asian Development Review （MIT Press Journals） 33 （ 1 ） 111 - 161 2016年03月

We propose a new dynamic transition analysis on the basis of a small open economy dynamic stochastic general equilibrium model. Our proposed analysis differs from existing static and conventional dynamic analyses in that shifts from a fixed exchange rate regime to a basket peg or a floating regime are explicitly explored.We apply quantitative analysis, using data from the People’s Republic of China and Thailand, and find that both economieswould be better off shifting from a dollar peg to a basket peg or a floating regime over the long run. Furthermore, the longer the transition period, the greater the benefits of shifting to a basket peg regime from a dollar peg regime owing to limited volatility in interest rates. Regarding sudden shifts to a desired regime, the welfare gains are larger under a shift to a basket peg if the exchange rate fluctuates significantly.

Promoting better lifetime planning through financial education

Naoyuki Yoshino, Flore-Anne Messy, Peter J. Morgan

Promoting Better Lifetime Planning through Financial Education （World Scientific Publishing Co. Pte. Ltd.） 1 - 205 2016年03月

共著

Surveys show that financial literacy levels are typically low around the world, despite the widening access to financial services and the increasing financial risks borne by households in many countries. This suggests that there will be mounting challenges for households and SMEs to invest wisely and effectively as societies age and governments shift away from defined benefit to defined contribution pension schemes. Individuals will increasingly have to make complex financial decisions to plan for their retirement and for a range of foreseen and unforeseen expenditures. All of these developments suggest that financial education should be part of a lifetime process that starts at an early age and is pursued throughout adulthood. The contributions in this book came from a symposium titled, Promoting Better Lifetime Planning through Financial Education, organized by the Asian Development Bank Institute, the Bank of Japan, the Japan Financial Services Agency, and the Organisation for Economic Co-operation and Development, held on 22-23 January 2015 in Tokyo. Amongst the topics discussed were: effective pension management, financial education curricula in schools, training for teachers of financial education, internationally comparable data on financial literacy and the evaluation of the effectiveness of financial education programs. There are also case studies on financial inclusion, regulation, and education in Indonesia, Pakistan, Philippines, Viet Nam, Thailand, and Japan.

Causes and Remedies of the Japan's Long-lasting Recession: Lessons for China

Naoyuki Yoshino, Farhad Taghizadeh-Hesary

Japan has suffered from sluggish economic growth and recession since the early 1990s. In this paper, we analyze the causes of the prolonged slowdown of the Japanese economy (the lost decade). Economics Nobel laureate Paul Krugman has argued that Japan's lost decade is an example of a liquidity trap. However, our empirical analysis shows that stagnation of the Japanese economy comes from its vertical IS curve rather than a horizontal LM curve, so the Japanese economy has been facing structural problems rather than a temporary downturn. The vertical IS curve is caused by an insensitivity of investment to a lower interest rate partly because of the decline of sales due to the aging population and firms not wanting to invest. The structural problems come from the aging demographic, which is often neglected by scholars and policy-makers, and also from the allocation of transfers from the central government to local governments, and the unwillingness of Japanese banks to lend money to startup businesses and small and medium enterprises (SMEs), mainly because of Basel capital requirements. Many countries, like China, are expected to face similar issues, particularly given the aging population. The present paper will address why the Japanese economy has been trapped in a prolonged slowdown and provide some remedies for revitalizing the economy.

Response of macro variables of emerging and developed oil importers to oil price movements

Farhad Taghizadeh-Hesary, Naoyuki Yoshino, Majid Mohammadi Hossein Abadi, Rosa Farboudmanesh

This paper assesses the impact of crude oil price movements on two macro variables, the gross domestic product (GDP) growth rate and consumer price index inflation rate, in the developed economies of the United States and Japan, and an emerging economy, the People's Republic of China (PRC). These countries were chosen for this research because they are the world's three largest oil consumers. The main objective of this study is to see whether these economies are still reactive to oil price movements. The results obtained suggest that the impact of oil price fluctuations on developed oil importers' GDP growth is much lower than on the GDP growth of an emerging economy. The main reasons for this lie in fuel substitution (higher use of nuclear energy, gas, and renewables), a declining population (for Japan), the shale gas revolution (for the United States), and strategic oil stocks and government-mandated energy efficiency targets in developed economies. All of these factors make developed economies more resistant to oil shocks. On the other hand, the impact of oil price movements on the PRC's inflation rate was found to be milder than in the two developed countries that were examined. The main cause for this is that the PRC experiences a larger forward shift in its aggregate supply due to higher growth, which allows it to avoid a massive increase in price levels following oil price shocks.
