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.     

The impact of the Second World War on US productivity growth1

This paper considers the productivity impact on the US economy of the period of war mobilization and demobilization lasting from 1941 to 1948. Optimists have pointed to learning by doing in military production and spin‐offs from military R & D as the basis for asserting a substantial positive effect of military conflict on potential output. Productivity data for the private non‐farm economy are not consistent with this view, as they show slower total factor productivity (TFP) growth between 1941 and 1948 than before or after. The paper argues for adopting a less rosy perspective on the supply side effects of the war.     

Effects of the first world war on the engineering industries of Estonia and Finland

Abstract

At the turn of the last century, international political tension intensified and the Great Powers accelerated their armament efforts. Conflicts in the Balkans threatened, as early as in 1908, to lead the two blocs of European countries into a great war for which especially Russia would have been very poorly prepared. The economic crisis of the early 1900s had increased the technological backwardness of the eastern Empire's heavy industry and armament compared with those of the other Great Powers. Partly for this reason the Russian government considered it best to stay outside the Balkan conflict at this point and to concentrate on modernising its army's weaponry and speeding up the building of strategic railways and harbours in the western parts of the Empire. In 1908 the Imperial government acquired a domestic loan of 200 million rubles, followed by a foreign loan of 525 million rubles, to finance these armament efforts.     

Access to Improved Water Sources and Rural Productivity: Analytical Framework and Cross‐country Evidence

Abstract: In this study we address the issue of access to drinking water in rural areas related to agricultural productivity performance. Considering an agricultural household model as our basic conceptual framework, we analyze the theoretical aspects of increasing the access rate to drinking water on agricultural productivity. First, we show that the increased access rate to drinking water is conducive to agricultural productivity due to increased intrinsic productivity of individuals and additional gain in time for agricultural production. Second, it transpires that the constraints on the access to drinking water may be costly in terms of decreased productivity and well‐being of rural people. Furthermore, based on a sample of 27 African countries over the period 1990–2010, estimation results do not reject the assumption that increasing access to drinking water has a positive effect on rural productivity growth. This positive effect is reinforced by the presence of a better sanitation system, even after controlling for country‐specific effects and for the characteristics of rural areas.     

Does China Transfer Productivity Enhancing Technology to Sub‐Saharan Africa? Evidence from Manufacturing Firms*

Abstract: This paper considers whether trade between China and sub‐Saharan Africa results in productivity‐enhancing technology transfers to sub‐Saharan African manufacturing firms. As trade flows between countries potentially results in interactions that lead to technological improvements in the production of goods and services, we parameterize the level of total factor productivity for African manufacturing firms as a function of foreign direct investment flow, and for the country in which it operates, trade openness with China, and its interaction with foreign direct investment. With micro‐level data on manufacturing firms in five sub‐Saharan African countries, we estimate the parameters of firm‐level production functions between 1992 and 2004. Our parameter estimates reveal that across the firms and countries in our sample, there is no relationship between productivity‐enhancing foreign direct investment and trade with China. In addition, increasing trade openness with China has no effect on the growth rate of total factor productivity. To the extent that total factor productivity and its growth is a crucial determinant of economic growth and living standards in the long run, our results suggest that increasing trade openness with China is not a long‐run source of higher living standards for sub‐Saharan Africa.     

Agricultural productivity and rural incomes in England and the Yangtze Delta,c.1620–c.18201

The productivity of agriculture in England and the Yangtze Delta are compared c.1620 and c.1820 in order to gauge the performance of the most advanced part of China vis‐à‐vis its counterpart in Europe. The value of real output is compared using purchasing power parity exchange rates. Output per hectare was nine times greater in the Yangtze Delta than in England. More surprisingly, output per day worked was about 90 per cent of the English performance. This put Yangtze farmers slightly behind English and Dutch farmers c.1820, but ahead of most other farmers in Europe—an impressive achievement. There was little change in Yangtze agricultural productivity between 1620 and 1820. In 1820, the real income of a Yangtze peasant family was also about the same as that of an English agricultural labourer. All was not rosy in the Yangtze, however, for incomes there were on a downward trajectory. Agriculture income per family declined between 1620 and 1820, even though income per day worked changed little since population growth led to smaller farms and fewer days worked per year. The real earnings of women in textile production also declined, since the relative price of cotton cloth dropped—possibly also because a larger population led to greater production. The implication is that the Yangtze family, unlike the English family, had a considerably higher real income c.1620, and that period was the Delta's golden age.     

Gerschenkron Redux? Analysing New Evidence on Joint‐Stock Enterprise in Pre‐War Shanghai

Alexander Gerschenkron (1904–78) famously postulated that the more backward an economy was at the outset of industrialisation, the more reliant it would be on state‐backed banks as a means of directing investment. Gerschenkron thereby implied that impersonal equity markets were likely to play a less significant role in countries aiming to catch up with the West. This article is aimed at examining Gerschenkron's thesis primarily through an analysis of shareholding in 1930s Shanghai. Drawing on newly discovered archival material as well as on recent studies, the paper clarifies the magnitude of joint‐stock enterprise and the ubiquity of stock‐exchange trade in a city that was by far China's most important economic hub. The pattern of joint‐stock enterprise in pre‐war China is compared with that of Japan, the first non‐Western society to become fully industrialised. The argument advanced is that Gerschenkron's thesis incorrectly played down the significance of impersonal equity markets to pre‐war Japan's successful industrialisation and to the limited nature of pre‐war China's industrialisation. Japan could sustain its industrialisation thrust in the early 20th century on a nation‐wide scale partly because of the growing vitality of its equity markets in Tokyo and Osaka. By contrast, China's pre‐war industrialisation was much less extensive because its equity markets were more limited.     

Public Expenditure,Growth and Poverty Reduction in Rural Uganda

Abstract: Using district‐level data for 1992, 1995, and 1999, the study estimated effects of different types of government expenditure on agricultural growth and rural poverty in Uganda. The results reveal that government spending on agricultural research and extension improved agricultural production substantially. This type of expenditure had the largest measured returns to growth in agricultural production. Agricultural research and extension spending also had the largest assessed impact on poverty reduction. Government spending on rural roads also had a substantial marginal impact on rural poverty reduction. The impact of low‐grade roads such as feeder roads is larger than that of high‐grade roads such as murram and tarmac roads. Education's effects rank after agricultural research and extension, and roads. Government spending in health did not show a large impact on growth in agricultural productivity or a reduction in rural poverty. Additional investments in the northern region (a poor region) contribute the most to reducing poverty. However, it is the western region (a relatively well‐developed region) where most types of investment have highest returns in terms of increased agricultural productivity.     

The decline of US manufacturing productivity between 1941 and 1948

The view that war benefits potential output has been influential in treatments of US mobilization for the Second World War, where it has been largely premised on the benefits of learning by doing in producing military durables. If the thesis that war benefits aggregate supply is correct, it is indeed within manufacturing that we should most likely see its effects. Total factor productivity within the sector in fact fell at a rate of −1.4 per cent per year between 1941 and 1948, −3.7 per cent a year between 1941 and 1944, and −5.1 per cent a year between 1941 and 1945. The emphasis on learning by doing has obscured the negative effects of the sudden, radical, and temporary changes in the product mix, the behavioural pathologies accompanying the transition to a shortage economy, and the resource shocks inflicted on the country by the Japanese and Germans. From a long-run perspective, the war can be seen, ironically, as the beginning of the end of US world economic dominance in manufacturing.     

Firm Productivity,Innovation, and Financial Development

How do firm‐specific actions—in particular, innovation—affect firm productivity? What is the role of the financial sector in facilitating higher productivity? Using a rich firm‐level data set, we find that innovation is crucial for firm performance as it directly and measurably increases productivity. The impact of innovation on productivity is larger in less‐developed countries. Evidence of financial sector development influencing the innovation‐productivity link is weak, but the effect is difficult to identify due to correlation between indicators of a country's financial and nonfinancial development. Furthermore, we find evidence that the innovation effect on productivity is more significant for high‐tech firms than for low‐tech firms.     

Exploring the Impact of Energy Sources on Production,Inequality and Poverty in Simultaneous Equations Models for South Africa

Abstract: This work adapts per capita income, energy demand (sub‐group decomposed), inequality and poverty frameworks in a simultaneous equations setting to investigate the role of energy sources on per capita income, inequality and poverty in South Africa. It finds that energy sources (particularly electricity and diesel) are important in estimating production functions. Gasoline, kerosene and coal all exacerbate poverty, with the highest impacts on abject poverty. It is better to disaggregate energy sources in order to capture resource‐specific details. Redistribution efforts that focus on reduction of between‐group inequality can also moderate energy use since between‐group inequality tends to increase the demand for most energy sources. Public efforts are yielding fruits in this direction and should be encouraged. Access to energy sources like electricity, diesel and gas are crucial for productivity enhancement, but for them to yield significant anti‐poverty fruits, efforts must also target broadening capital access by the poor.     

Industrial Diversification and Its Impact on Productivity Growth in Taiwan's Electronics Industry*

The present study attempts to link plant‐level production diversification to productivity growth in Taiwan's electronics industry. An account of the role of the Taiwanese government over the last 2 decades leading to the take‐off of its electronics industry is briefly discussed. We reviewed production activities of more than 20 000 Taiwanese electronics plants during the period 1992–1999. In an inter‐industry comparison, we find that at the four‐digit and seven‐digit industry levels, Taiwanese electronics production plants exhibit a significantly higher degree of product diversification than plants in the manufacturing sector as a whole. Econometric results positively identify diversification as a source of significant productivity growth across all electronics plants classified in the related industry groups.     

Cattle numbers,biomass, productivity and land degradation in the commercial farming sector of Namibia, 1915‐95

As part of a natural resource accounting project undertaken in Namibia, livestock accounts have been drawn up and are being used to analyse the relationship between numbers of livestock, rainfall, land degradation, and economic and policy variables. Part of the analysis concerns an investigation into trends in cattle numbers, changes in cattle biomass and the productivity of livestock in commercial areas. Cattle numbers increased from 1914 until 1960, then declined steadily to half that number. This decline was at least partly due to deliberate actions by farmers to improve herd productivity and production efficiency. Although beef production did not decline over this period, productivity is still lower than potential industry standards. Range degradation (bush encroachment) may have contributed to this curtailment. This investigation has implications for an understanding of long‐term carrying capacity, land degradation and rangeland management, and for agricultural development policies in Namibia and similar regions in southern Africa.     

Hand looms,power looms,and changing production organizations: the case of the Kiryū weaving district in early twentieth‐century Japan

The Kiryū silk weaving district, located 200 kilometres north of Tokyo, has been one of the most advanced silk weaving districts since the Tokugawa period (1603–1868). In the 1870s, it was a pioneer in the export of silk products from Japan and the leading producer of traditional Japanese kimono and obi (sash belts) for domestic markets. This study finds that the developmental process of the Kiryū district from 1895 to 1930 can be divided into at least two phases, that is, one of gradual growth based on an inter‐firm division of labour using hand looms and one of dynamic development based on the factory system using power looms. Weaving manufacturers‐cum‐contractors pioneered gradual growth by sub‐contracting with rural village out‐weavers and with a number of specialized, supporting firms in Kiryū town, and grew faster than factory production systems. New joint‐stock firms played the role of genuine entrepreneurs by introducing power looms, thereby realizing significant economies of scale. During this new phase, the weaving manufacturers‐cum‐contractors survived and also introduced new production systems.     

Innovation and Firm‐Level Productivity: Evidence from Bangladesh

In this paper, the labor productivity impact of manufacturing firms’ innovation in Bangladesh, a region which has, to date, been understudied in this respect, is examined through World Bank Enterprise Survey data from 2003 to 2006. We apply the Cobb–Douglas production function, augmented with innovation‐related inputs (and other expected sources of productivity) in a simultaneous three‐equation system connecting R&D to its determinants, innovation output to R&D, and productivity to innovation output; and in a two‐equation system connecting innovation output to its determinants and productivity to innovation output. Our results reveal that Bangladeshi firms’ process innovation is an important factor for their labor productivity, whereas the significant effect of product innovation is not clearly established.     

Productivity Growth in Different Plant‐size Groups in the Malaysian Manufacturing Sector*

In the present study, we develop a stochastic frontier production model that allows for different groups of firms to have different patterns of technical efficiency over time. We apply our model to the Malaysian manufacturing sector to decompose total factor productivity growth into technical efficiency change and technical progress for different plant size groups (e.g. large and small) in seven industries during 2000–2004. Our empirical results indicate that technical efficiency has worsened across all industries and plant‐size groups. In contrast, we find evidence of substantial technical progress in all industries. In fact, technical progress has been larger than technical efficiency deterioration in most industries and plant‐size groups, leading to total factor productivity growth. Our analysis identifies the industries and plant‐size groups that lag the most in terms of productivity, and thus have the greatest scope for policies that facilitate productivity growth.     

Agricultural development in Southern Africa: Theory,lessons and the food crisis in Africa

In this paper a household economics theory of farm‐household production in the Southern African context is presented which (a) places a new interpretation on the causes of low productivity per person and unit of land in the African farming sector, (b) demonstrates that even where improved food crop technology is widely adopted it may have a very limited impact on marketed production, and (c) contributes to an understanding of why Africa's food production per person continues to fall despite per capita aid inflows which have exceeded those for any other continent over the last decade.

Wages,Productivity and Aging

In this article, we estimate age-based wage and productivity differentials using Canadian linked employer-employee data from the Workplace and Employee Survey 1999–2005. We use data at the workplace level to estimate production functions, taking into account the age profile of its workforce. Data on workers is used to estimate wage equations that also depend on age. Results show concave age-wage and age-productivity profiles. On average, we find that wages do not deviate significantly from productivity. For certain sub-groups, our results suggest some discrepancies between wages and productivity. This is the case for older workers with at least an undergraduate degree for whom productivity appears to be lower than their wages, while the reverse seems true for younger men. However, even in those cases, productivity differentials are too imprecise to draw any firm conclusions.     

Latin America and the Great War: A preliminary survey of developments in Chile,Peru, Argentina and Brazil

In this paper we present some preliminary ideas on a comparative study of the economic and social effects of World War I on Latin America. We argue that this issue has generally been conceived too narrowly, and that the events of the war years have much to tell us about the nature of capitalist development in the region. We begin by outlining some of the major external factors which influenced the course of economic change in the years before 1914. The initial impact of the war is then considered, particularly with regard to finance, trade and social dislocation. Finally, we briefly examine similar topics during the remaining war years. We conclude by arguing that the war did not provide an opportunity to alter the course of economic growth, but tended to highlight the weaknesses and magnify the contradictions of Latin America's brand of capitalist development.
