Total factor productivity in South African agriculture, 1947‐91

Indices of total factor productivity (TFP) measure aggregate output per unit of aggregate input, providing a guide to the efficiency of agricultural production. This article outlines the relationship between production functions and TFP indices. Then, an index is constructed for South African agriculture for the period 1947‐91. The index shows that TFP grew at an average rate of 1,3 per cent per annum. However, TFP growth has increased since the reforms of the early 1980s. Since capital has been more realistically priced relative to labour, greater productivity growth has gone together with increasing employment, which must have improved social welfare.     

Gender Inequalities and Economic Efficiency: New Evidence from Cassava‐based Farm Holdings in Rural South‐western Nigeria

Abstract: It is a widely accepted fact that persistent inequality between men and women constrains a society's productivity and ultimately slows its rate of economic growth. The economy pays for this inequality in reduced labour productivity today and diminished national output tomorrow. Motivated by this, the study aim is to assess the possibilities of enhancing productivity gains by improving the efficiency of small‐scale agriculture through gender‐responsive intra‐household allocation of resources in south‐western Nigeria. The study adopts a stochastic parametric decomposition method which yields efficiency measures that are not distorted by statistical noise to estimate the efficiency level of resource allocation by small‐scale cassava producers. The results indicate that average overall productive efficiency in the sample was 75.78 per cent, implying that small‐scale cassava farmers in the sample could reduce total variable cost by 24.22 per cent if they reduce labour, fertilizer, land and capital applications to levels observed in the changing input mix (technical efficiency) and then obtain optimal input mix for the given input prices and technology (allocative efficiency). The average technical efficiency and allocative efficiency indexes for the sample were 82.2 per cent and 92.2 per cent respectively. Also, evidence from empirical analysis of data from the male respondents showed that the average economic, technical and allocative efficiency indexes were 88.06 per cent, 89.34 per cent and 78.67 per cent respectively while the same computed for the female sample were 94.9 per cent, 74.85 per cent and 71.03 per cent respectively. Labour was the most limiting factor in cassava production suggesting that the technologies that enhance the productivity of labour are likely to achieve significant positive effects on cassava production. The paper shares the notion that producers' control over the means of production and impact of development are related and has influence on the economic efficiency and growth of society. Again, technical inefficiency constituted a more serious problem than allocative inefficiency, thus most cost savings will accrue to improvement in technical efficiency.     

Productivity growth in Indonesian agriculture, 1961–2000

This paper uses an index number approach to measure total factor productivity (TFP) growth in Indonesian crop and livestock agriculture from 1961 to 2000. Tornqvist-Theil chain-weighted indices of output, input and TFP are developed to minimise biases that may result from relative changes in input and output price aggregation weights. The results indicate that agricultural TFP growth accelerated in the 1970s and 1980s but stagnated in the 1990s. Without new efforts to increase productivity in agriculture, Indonesia's goal of using agricultural growth to generate broad-based rural development and further reduce poverty may be undermined.     

ICT and Productivity Growth in the United Kingdom

This paper develops new estimates of investment in and outputof information and communication technology (ICT). These newestimates imply that GDP growth has been significantly understated,particularly since 1994. A growth-accounting approach is employedto measure the contribution of ICT to the growth of both aggregateoutput and aggregate input. On both counts, the contributionof ICT has been rising over time. From 1989 to 1998, ICT outputcontributed a fifth of overall GDP growth. Since 1989, 55 percent of capital deepening (the growth of capital per hour worked)has been contributed by ICT capital; since 1994 this proportionhas risen to 90 per cent. ICT capital deepening accounts for25 per cent of the growth of labour productivity over 1989–98and 48 per cent over 1994–8. But even when output growthis adjusted for the new ICT estimates, both labour productivityand TFP growth are still found to slow down after 1994.     

The development of stage coaching and the impact of turnpike roads, 1653–1840

This article uses newspaper advertisements to chart the changes in speeds and fares of stage coaches, identifying the main periods of increasing speeds among London coaches as the 1760s–80s and 1810s–20s, separated by a period when speeds declined. It then measures productivity growth. Fares of London coaches in 1835–6 were about 27 per cent of what they would have been but for improvements in horses, vehicles, and roads from 1750, and the two main periods of productivity growth correspond to those of rising speeds. Speeds and productivity of regional coaches increased more smoothly. The rising productivity firmly identifies road transport as one of the modernizing sectors of the economy. New figures are put forward for the growing number of London and regional coaches, indicating rapid growth in passenger miles. While turnpike trusts had little impact before the 1750s, their increasing effectiveness, together with the use of steel springs and improved horses, was crucial to the rising productivity of the 1760s–80s, and even more so to that of the 1810s–20s. The cross roads were apparently poorer than London roads in the late eighteenth century, but thereafter the gap narrowed.     

Monetary Aggregates Targeting,Inflation Targeting and Inflation Stabilization in Ghana

The central bank of Ghana (BoG) has operated monetary aggregates targeting and inflation targeting since the 1980s, to ensure enhanced output growth, low unemployment and stable, low inflation. Under inflation targeting, the inflation rate averaged 13.26 per cent per annum between 2007 and 2015, compared with 29.22 per cent per annum under monetary aggregates targeting. The relatively lower inflation rates notwithstanding, an average inflation rate of 13.2 per cent per annum is far above the medium‐term target of 8 per cent. This paper has examined the effectiveness of monetary aggregates targeting and inflation targeting in keeping inflation at moderate levels. The autoregressive distributed lag (ARDL) model was applied to the data covering the period 1970–2015. The results show that monetary targeting has steered inflation to moderate levels only in the short run while inflation targeting has maintained low inflation rates in both short run and long run. But neither regime has kept inflation at stable levels and within the target band, due to the sluggish transmission of broad money supply and prime rate changes to inflation. We implore the monetary authorities to strengthen the institutional setup for steering short‐term interest rates in Ghana. They should also enhance the BoG Act 2002 (Act 612), to develop secondary anchors and rules around output, money supply and fiscal deficit. Finally, the monetary policy committee should monetary policy credibility and transparency through strengthening its communication framework.     

Agricultural productivity growth in traditional and transitional economies in Asia

This paper reports estimates of agricultural productivity growth in Asian countries, with special attention to the transition economies. A parametric output distance function approach is formulated to decompose total factor productivity (TFP) growth into its associated components and to examine how input and output intensities shift in response to the adoption of innovations. The results show that by including the transition economies, Asia achieved healthy TFP growth at an annual average rate of 1.9 per cent. However, TFP growth and its components differ widely across the transition countries and at different stages of the transition periods within these countries.     

Forces of economic growth in China,India, and other Asian countries

This paper applies different approaches to modelling sources of economic growth from time series and panel data sets for 10 Asian countries over the period 1970–2010. After being subjected to fragility tests, the cross‐country estimates indicate that investment, together with policy variables and openness to trade, explains about 90 per cent of the estimated 3.2 per cent steady‐state growth rate for the region. Regional growth policy points to expanding trade, supporting financial development, and maintaining sound investment environments. Although country‐specific growth effects vary, the results imply that different estimation methods, combined with fragility tests, can help establish stronger links between growth theory and policy advice.     

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.     

Import Competition, Productivity, and Restructuring in UK Manufacturing

We discuss the literature on the importance of entry and exitfor raising productivity growth. Using micro data for the UKfor a period from 1980 to 2000, we find that the share of productivitygrowth accounted for by entry and exit has increased considerably:from around 25 per cent in the 1980s to around 50 per cent inthe 1990s. We then ask to what extent increased globalization—measuredas sectoral import penetration—might have explained thisand find effects from both globalization and information andcommunication technology.     

THE FOOD SECURITY PROBLEM IN ETHIOPIA – A SUPPLY SIDE ANALYSIS

Since 1961 Ethiopia has been ruled by a Monarchy, a Marxist military dictatorship, and presently by a coalition of political parties that came to power in 1991after a protracted civil war. These three governments have pursued different ideologies in formulating policies to guide agricultural development. However, to date Ethiopia remains food insecure. Ethiopian agriculture is dominated by peasant farmers and 85 per cent of the population is rural. Rural poverty and, hence, food insecurity is intricately related to insufficient land and a lack of long‐term tenure security. The aggregate country level food security was assessed using various indicators for the periods of the three governments. The growth rates and the variability in the indicators suggest that Ethiopia is suffering from both chronic and transitory food insecurity.     

Does Productivity in the Formal Food Sector Drive Human Ebola Virus Infections in Sub‐Saharan Africa?

As the hunting, butchering, processing, and consumption of bushmeat is a potential source of human Ebola virus (EV) infections, the extent to which bushmeat is a substitute for food produced and sold in the formal sector suggests that the relative price of food could matter for the incidence of human EV infections. This paper considers if productivity in the food sector is a driver of human EV infections in sub‐Saharan Africa. We estimate count data specifications of country level human EV infections as a function of food sector productivity in sub‐Saharan Africa over the 1976–2013 time period. Our parameter estimates suggest that if productivity in the food sector was on average 1 per cent higher over the 1976–2013 time period, the incidence of human EV infection would have been 42.5 per cent lower. This is consistent with bushmeat being a substitute for food produced in the formal sector, as food productivity increases lower the price of formal food relative to bushmeat. Our findings suggest that as productivity in the formal food sector is a driver of human EV infections in sub‐Saharan Africa, policy interventions that increase food productivity would enable Millennium Development Goal outcomes related to hunger, disease mitigation, and sustainability of wildlife.     

An annual index of Irish industrial production, 1800–1913

We assemble the Irish industrial data currently available for the years 1800–1921, the period during which the entire island was in a political union with Great Britain, and construct an annual index of Irish industrial output for 1800–1913. We also construct a new industrial price index. Irish industrial output grew by an average of 1.3 per cent per annum between 1800 and the outbreak of the First World War. Industrial growth was slightly slower than previously thought, especially during the two decades immediately preceding the Great Famine. While Ireland did not experience absolute deindustrialisation either before the Famine or afterwards, its industrial growth was disappointing when considered in a comparative perspective.     

PRODUCTIVITY AND FIRM DYNAMICS: CREATIVE DESTRUCTION IN INDONESIAN MANUFACTURING, 1994–2000

This paper examines the entry and exit, and the labour productivity, of Indonesian manufacturing firms with 20 workers or more, using a firm-level panel dataset constructed for the years 1994–2000. Overall change in manufacturing labour productivity reached 27.2%—an average growth of 3.5% per annum—between 1994 and 2000, a period that includes the 1997–98 Asian financial crisis, which hit Indonesia hard. Vibrant firm dynamics characterised this period, in which about 10% of manufacturing enterprises were renewed in any one year. By 2000, one-third of all enterprises in existence in 1994 had closed, but the number of enterprises that closed was lower than the number that entered and survived up to the year 2000. The replacement of exiting firms with newly entering firms contributed significantly to increases in overall labour productivity. Regulatory reform in support of this process should lead to gains in productive employment for Indonesian workers.     

Slave prices,the African slave trade,and productivity in the Caribbean, 1674–18071

We draw wide‐ranging implications about slave productivity change by making use of newly collected data on the prices paid for nearly 230,000 slaves as they arrived in the Americas from Africa between 1674 and 1807. Prices for the product that most slaves were destined to produce‐sugar‐are also available. Together the comprehensive series allow us to derive annual measures of average slave productivity and to compare productivity trends across different sectors of the Caribbean. Average productivity rose throughout the Caribbean, and the pattern of average productivity change across regions was similar, indicating an open slave market. These averages mask sharp differences in the growth of demand for slaves among regions, as reflected by their slave populations. Between 1700 and 1790 the increase in demand ranged from 90 per cent in Barbados to 600 per cent in Jamaica and Cuba; while total factor productivity overall may have doubled. The slave trade accommodated the rising demand. It also served to offset population attrition among the slaves.     

基于全要素生产率的中韩经济增长因素分析

20世纪60年代以后,东亚经济的高速发展,特别是80年代中韩经济的快速发展引起了国内外学术界的关注,本文利用增长会计法和Malmquist指数法对中国和韩国的经济增长因素进行了分析,结果发现,2002～2009年中国全要素增长率的贡献率从1981～2001年的23.29%上升到28.88%,全要素增长率的贡献超过了劳动投入的贡献率。1981～1998年期间韩国的经济增长率为7.64%,其中,60%以上是靠资本投入来实现的,25%是依靠劳动的投入,但在1999～2009年期间全要素生产率的贡献率达到了42%,中国与韩国的经济增长开始走向依靠技术进步和创新发展的道路。     

Real Output and Labour Productivity in Indonesian Manufacturing, 1975–90

This article presents estimates of purchasing power parities, real output and labour productivity in medium and large scale manufacturing in a binary comparison between Indonesia and the USA in the benchmark year 1987, It applies an industry of origin approach, comparing product unit values from the censuses of both countries. The 1987 PPP for manufacturing was Rp 1,200/$. Gross value added per person employed in 1987 was 10% of that in the USA. With the use of national time series, the 1987 benchmark was extrapolated backwards and forwards to derive productivity comparisons for the years 1975–90 in 15 branches of manufacturing. 1975–80 was a period of catch-up, with labour productivity increasing from 7.7 to 10.6% of the US level. Between 1980 and 1990 catch-up stagnated: relative productivity remained unchanged despite considerable productivity growth in Indonesia, Comparisons with other Asian economies show that labour productivity in Indonesia was somewhat higher than in India, but was still lower in 1990 than that of South Korea in 1970.     

Growth or stagnation? Farming in England, 1200–1800

Estimates of English income in Broadberry et al.’s British economic growth, 1270–1870 are founded upon a fourfold growth of farm output, and output per farm worker, over this interval. This article shows, using four separate tests, that farm output growth must have been much more limited. The tests are, first, whether in 1300 there was enough work at harvest to employ all the labour force; second, whether the value of output per worker in agriculture was greater than the annual earnings of workers; third, whether the implied relative outputs per acre of arable versus pasture were reasonable; and fourth, whether a much shorter medieval work year was possible. An alternative index of farm output consistent with the labour supply, wages, and farm rents is derived. This shows much less growth during the period 1270–1800. Overall economic growth in England during these years must consequently have been far less than Broadberry et al. estimate.     

A new study of the Chinese regions in a neoclassical framework of models of growth

This study tests economic growth and convergence across the Chinese provinces during the period 1981–2005 based on augmented neoclassical growth models where land is included as a production input. A positive steady-state growth of per capita output cannot be sustained if the population growth rate or the output elasticity of land is sufficiently high. The study implements a panel data approach and shows that land may have an output elasticity as high as 1/3, suggesting that the natural environment indeed poses an important constraint on China's economic growth. In this study of the Chinese provinces, the panel data approach has implied much higher rates of conditional convergence in per capita output, compared with cross-section estimations.     

Industrial Productivity Convergence in China

This paper examines the convergence process of industrial productivity between Chinese regions. Both σ- and β-convergences are investigated using a panel data set of 30 provinces and autonomous regions over the period 1985–1999. Unconditional σ- and β-convergence methods fail to detect productivity convergence over the whole sample period, although they suggest convergence during a sub-period 1985–1990. The estimates of a human capital enhanced production function, with the constant return to scale constraint, show that productivity gaps between Chinese regions declined during 1985–1999 with a rate of convergence of around 1.3% per annum. Similar results are also found when the data are disaggregated into three broader geographic regions.
