The supplier network and aircraft production in wartime Japan

The Japanese aircraft industry, which was very small scale before the Second World War, became Japan's largest manufacturing industry by the end of the war. This article explores the basis for the growth of the aircraft industry during this time by focusing on Mitsubishi Heavy Industries Company's No. 5 Works. It was revealed that during the war, the supply of basic inputs increased substantially: labour force, equipment, and ‘machinery parts’ were in sufficient supply and none of these was a binding constraint on production. The binding constraint existed in the supply of ‘special parts’. In other words, aircraft production expanded as the supply of special parts increased. This increase in the supply of special parts and still faster growth in the supply of machinery parts came about through the expansion of the supplier network in terms of both the number of suppliers and the geographical area in which they were located. These findings imply that outsourcing played a key role in the growth of aircraft production in wartime Japan.     

Does agricultural trade liberalization increase risks of supply-side uncertainty?: Effects of productivity shocks and export restrictions on welfare and food supply in Japan

Agriculture is the focus of much contention in free trade negotiations. The Japanese government is against liberalizing the rice trade on the grounds that it would threaten “national food security” in the events of such shocks as crop failure and embargoes. Trade liberalization is expected to make the Japanese economy more dependent upon food imports and, thus, more susceptible to these risks. Using a computable general equilibrium model with a Monte Carlo simulation, we quantify the welfare impacts of productivity shocks and export quotas by major rice exporters to Japan and found little evidence of Japan suffering from such shocks.     

Micro-aspects of monetary policy: Lender of Last Resort and selection of banks in pre-war Japan

This paper explores how the Bank of Japan (BOJ) dealt with the trade-off between stability of the financial system and the moral hazard of banks in pre-war Japan. The BOJ concentrated Lender of Last Resort (LLR) loans with those banks that had an established transaction relationship with the BOJ. At the same time, the BOJ carefully selected its transaction counterparts, and did not hesitate to end the relationship if the performance of a counterpart declined. Further, the BOJ was selective in providing LLR loans. Through this policy, the BOJ could avoid the moral hazard that the LLR policy might otherwise have incurred.     

AGRARIAN LAND TENANCY IN PREWAR JAPAN: CONTRACT CHOICE AND IMPLICATIONS ON PRODUCTIVITY

We study the tenancy contract choice and its impact on productivity in the prewar Japanese agriculture, where a unique contractual form, the rent-reduction contract, was predominant. Theoretically, this contract is more efficient than share tenancy or fixed-rent contract in terms of provision of incentives and risk-sharing, and thus raises the question of why such an efficient contract was uncommon outside Japan. We argue that transaction costs on the execution of rent reduction were the key element in the adoption of this contract. In prewar Japan, local communities played some role in governing the process of rent reduction and mitigated such costs. Thus the study proposes transaction costs and institutions as additional determinant of tenancy contract choice. We also find that higher prevalence of tenancy was associated with lower average rice yield at the prefectural level and such correlation was stronger in prefectures with a greater proportion of share tenancy.     

The role of the merchant coalition in pre-modern Japanese economic development: an historical institutional analysis

This paper examines the economic role of the merchant coalition (kabu nakama) in Japan during the 18th and the first-half of the 19th century. During this period, public sector enforcement of contracts was imperfect. Kabu nakama substituted for the public sector, using a multilateral punishment strategy. When the government (Bakufu) prohibited kabu nakama in 1841, the growth rate of the real money supply contracted, efficiency of price arbitrage declined, and the inflation rate increased.     

The Performance of Development Banks: The Case of the Reconstruction Finance Bank

This paper analyzes the performance of the Reconstruction Finance Bank (RFB) in order to shed light on the role of development banks in fostering economic growth. The RFB played a large role in Japan′s transition from war-time command economy to a market economy in the early post-war period. We use individual firm level data on sales, profits, and loans from the RFB, and find that, initially, the RFB was making loans to firms with below-average performance. We then find that this was partly a result of political interventions into the loan policy of the RFB. In fact, we also find evidence of improvements in the performance of the RFB after its loan policy became more independent. Implications for developing economies are also discussed. J. Japan. Int.

Health and Income Variation – A Panel Data Study on the Developed and Less Developed Economies

In this paper, human capital in the form of ‘health status’ is introduced into a neoclassical economic growth model as one of the main factors differentiating rich and poor countries. Various panel data models are used to examine how health and other growth factors affect average income in different countries. Our main empirical finding indicates that a one-year increase in life expectancy (the health status measure) raises GDP per capita by 0.5–0.9%. Based on this result, a baseline health status can be established to help poor countries achieve a targeted economic growth rate.     

‘Voice’ and ‘exit’ in Japanese firms during the Second World War: Sanpo revisited*

During the Second World War, the Japanese government and private sector searched for and implemented new mechanisms for coordination and motivation. One of these was sangyo hokokukai (sanpo). The Sanpo unit was basically an organization of the employer and employees of each firm, which held meetings to moderate labour relations. As a result of government policy to promote sanpo units, around 70 per cent of the total workers in Japan were organized into sanpo units in the early 1940s. As the members of trades unions and the workers of the companies that had factory committees were only 7 per cent and 5 per cent of the total workers in 1936 respectively, sanpo was the first large‐scale mechanism for Japanese employees to have a voice. This article examines the role of sanpo, using prefecture‐level and firm‐level data, based on a framework integrating the ‘voice view’ of unionism and transaction cost economics. It was found that sanpo reduced the participation rate in labour disputes, and enhanced labour productivity at least for some of the time.
