The direct impact of the relocation of farm labour on Chinese grain production

The shift from collective to household-based farming and the move towards a market economy have increased the opportunity cost of grain production and caused a withdrawal of labour from grain farming in China. Since Chinese grain production is important to both China and the world, there are concerns about whether such a farm labour relocation will have a destructive impact on China's grain production. The previous production function studies ignored the effects of changes in labour quantity and quality on grain production. Using recently available sample survey data on Chinese farm households, this paper incorporates production function analysis with human capital analysis to examine the direct impact of the relocation of farm labour on China's grain production. It has found that the relocation of farm labour has not harmed the Chinese grain production in general, but its impact varies across regions with different factor endowments that affect the choice of farming technology.     

Cost heterogeneity and the destination of Japanese foreign direct investment: A theoretical and empirical analysis

This paper first of all develops a Cournot oligopolistic model with heterogeneous firms to examine each firm's choice between export-oriented foreign direct investments (FDI) and FDI to serve the host-country market. It is shown that there exist a critical level of efficiency such that all firms below that level choose the former and those above it the latter. The hypothesis is tested using firm-level data on 118,300 Japanese firms covering the entire manufacturing sector. Multinomial logit estimates strongly support our theoretical findings.     

Productivity growth, technological progress, and efficiency change in chinese agriculture after rural economic reforms: A DEA approach

This study applies a data envelopment analysis (DEA) approach to analyze total factor productivity, technology, and efficiency changes in Chinese agricultural production from 1984 to 1993. Twenty-nine provinces in China were classified into advanced-technology and low-technology categories. The Malmquist (1953) productivity measures were decomposed into two components: technical change index and efficiency change index. The results show that total factor productivity has risen in most provinces for both technology categories during the 1984–1993 period. Technical progress was mostly attributed to Chinese agricultural productivity growth after the rural economic reforms. The deterioration in technical efficiency in many provinces indicates China has great potential to increase productivity through improved technical efficiency. Enhancing rural education and research and development (R&D) in agriculture may also help farmers to improve technical efficiency and productivity in agricultural production.     

Land use change and environmental stress of wheat, rice and corn production in China

Grain self-sufficiency is one of the most important agricultural policy goals in China. With only modest imports, China has succeeded in feeding 22% of the world's population on only 7% of its land. However, a high price has been paid for this enormous achievement. Increase in grain yields, in particular in rice, as the main source of production growth, relied heavily on intensive use of physical inputs and increasing intensity of farming systems. Soil degradation, water scarcity, and severe pollution were among the consequences as well as declining efficiency of fertilizer application. Using county-level panel data from 1980 to 2003 and graphical (GIS-based) analysis, this paper first looks at the spatial change of the major grain production across regions over the past two decades, towards the northern and northeastern provinces. The analysis is complemented by using a random panel data model, which underscores the significant influence of land availability, degree of urbanization, and government policy on grain production. Finally, this analysis addresses environmental stress which includes both soil degradation and water shortage. The latter is already severe in many of the traditional grain producing areas, but will now become a bigger problem in the “new” grain producing areas, as these have traditionally much less water resources. Hence, while the economic rational of the “grain shift” towards the northern and northeastern regions is understandable, its sustainability is not guaranteed.     

On the export-led growth hypothesis for the little dragons: An empirical reinvestigation

The export-led growth hypothesis is tested using quarterly time series data for Hong Kong, Korea, and Taiwan and by constructing a vector autoregression (VAR) model. The Granger no-causality procedure developed by Toda and Yamamoto [1995] was applied to test the causal link between real export growth and real industrial output growth. Three distinct features in this paper stand out against earlier studies on the Little Dragon countries of Asia. First, going beyond the traditional two-variable relationship, a VAR model is built in the production function context to avoid a possible specification bias. Second, Riezman et al. [1996] are followed to test the export-led growth hypothesis while controlling for the growth of imports to avoid producing a spurious causality result. Third, the sensitivity of causality test results under different lag structures is tested along with the choice of optimal lags. In particular, the methodology developed by Toda and Yamamoto is expected to improve the standard F-statistics in the causality test process. The principal result from this research cannot offer support for the export-led growth hypothesis.     

A note on the CERU-MoA grain farm household survey in China

During the period 1994–1995 the Chinese Economy Research Unit (CERU), University of Adelaide, Australia and the Department of Policy, Reform and Law, Ministry of Agriculture (MoA),¹ the People's Republic of China, jointly designed and conducted an annual sample survey of about 1000 farm households in five Chinese provinces: Guangdong, Jilin, Jiangxi, Sichuan and Shandong. The CERU-MoA survey is a part of the ACIAR (Australian Centre for International Agricultural Research) project on China's grain production and marketing during 1994–1996.² Based on this survey a large database has been established which contains cross-household data on population and labour, land, grain production and marketing, food consumption, income and related policy issues.³     

Do Chinese farmers reinvest in grain production?

Grain production is affected by the relocation of farm household labour from on-farm to off-farm activities and by an increase in the investment in grain production as a result of increase in farm household income that occurs along with such a labour shift. This study uses a recent farm household survey data to examine whether Chinese grain households do reinvest in grain production. It has found that household income growth contributes to higher investment in grain production although a higher share of non-agricultural income has a negative effect. The authors' other research has found a negligible direct impact of farm to non-farm labour transfer on grain production. We may conclude that in the near future, the total impact (direct and indirect) of labour transfer from farm to non-farm production on grain output is expected to be positive. In the long run, in may become negative when more and more labour shifts out of grain production and marginal product of labour becomes positive.     

A decomposition analysis of income inequality of Chinese rural households

This paper reports an application of household survey data collected from grain producing areas in five provinces of China to issues of the determinants of rural inequality. Previous studies suggest that non-agricultural activities have been the major cause of rural income inequality, which has important implications for policy formulation. However, our results show that inequality within the grain producing areas was also very high, with differences in crop income as the major source of inequality. The policy implications are also different from those of previous studies. While some suggest that an increase in agricultural income can reduce inequality, our results indicate that this is not universally true. In some cases, whether the increase in crop income has come from state procurement also matters. These results call for a more cautious and area-specific approach to policy formulation as far as inequality is concerned.     

An alternative method of measuring economic efficiency: The case of grain production in China

The objective of this paper is to suggest a simple method to gauge the economic efficiency of firms, when there are no reliable price data. Applying the suggested method on the recent Chinese farm-household survey data collected during 1993 and 1994, this study shows that majority of grain farmers in China are not producing at the optimum levels which yield maximum profits. The analysis also indicates that output can be increased by consolidating rather than further segmenting the operational area of grains.     

THE SOUTH AFRICAN AGGREGATE PRODUCTION FUNCTION: ESTIMATION OF THE CONSTANT ELASTICITY OF SUBSTITUTION FUNCTION

This paper assesses the validity of the constant elasticity of substitution (CES) and the Cobb-Douglas (CD) production functions in modelling the aggregate production function and computing the total factor productivity (TFP) in South Africa for the period 1970-2006. The CES function is estimated with Nerlove's two-step procedure using the autoregressive distributed lag (ARDL) cointegration and the Kalman filter estimation techniques, while the CD production function is estimated using the Kalman filter technique. The results of the forecast performance of the two model specifications show that the CD specification outperforms the CES for the period 1970-2006, although the CD specification may be too restrictive.     

Incomplete property rights, exposure to markets and the provision of environmental services in China

This paper uses data from a 2003 rural survey to examine the determinants of household provision of environmental services under China's Sloping Land Conversion Program (SLCP), the largest payments for environmental services program in the developing world. The paper examines the determinants of plot-level survival rates of program-planted trees and grasses. It finds that household rights over retired land as well as autonomy in program decision-making (which we argue on the basis of supportive evidence are plausibly exogenous to post-retirement outcomes) have important and potentially countervailing impacts on the provision of environmental services targeted by the program. Households permitted to select what to plant obtain better program outcomes, but do not make the choices that the government would like them to, while those permitted to decide what land to retire perform worse. The analysis also finds that households more vested and experienced in agriculture and with less exposure to off-farm labor markets fare better in managing their planted trees. Significant learning-by-doing effects are also evident, suggesting that greater technical support to farmers could improve outcomes and lower program costs.     

DOES SENDING FARMERS BACK TO SCHOOL HAVE AN IMPACT? REVISITING THE ISSUE

The Farmer Field School (FFS) is an intensive training program providing farmers with science‐based knowledge and practices, including integrated pest management. Recently there has been intensive debate as to whether or not this kind of training has any significant impact. Most case studies argue that the impact, in terms of a farmer's ability to reduce the use of pesticides while increasing yields, is significant. However, panel data studies using household panel data sets for Indonesia have not been able to confirm that this is the case. The present paper uses panel data available from previous panel data studies and applies a new model specification to reevaluate whether or not the FFS induces better performances among farmers enrolled in the program and also among their neighbors, who are expected to receive some spillover knowledge from the FFS alumna.     

Output-Inflation Trade-Off at Near-Zero Inflation Rates

The purpose of this paper is to provide new evidence about the cost of near-zero inflation using Japanese data. We test the hypothesis that the short-run Phillips curve becomes flatter as the rate of inflation approaches zero. In implementing the test, we pay special attention to how to control for other factors affecting the rate of inflation. First, we use the skewness of the distribution of relative-price changes as a measure of supply shocks. Second, we use information contained in the cross-prefecture Phillips curve to control for changes in the expected rate of inflation. Through a series of empirical analyses, we find evidences consistent with the hypothesis. In particular, we find that the estimated slope in the 1990s is smaller than before. J. Japan. Int.

The role of production fragmentation in international business cycle synchronization in East Asia

This paper analyzes factors contributing to the observed increase in international business cycle synchronization between eight East Asian developing countries and the major developed economies of Japan and the United States. To this end, a two-country dynamic general equilibrium (DGE) model is proposed which focuses on the role of production fragmentation among these countries. A key feature of the model is that it includes the trade in differentiated capital goods, which are added to the capital stock for production, and the technology embodied in these capital goods. The parameters of the model are calibrated using actual data of the countries included. Model simulations are conducted for two periods (1993–1997 and 1999–2005), before and after the Asian financial crisis, showing that the increase in business cycle synchronization can be attributed mainly to the growing fragmentation of production activities.     

Poverty and firewood consumption: A case study of rural households in northern China

This paper discusses the determinants of firewood consumption in a poor township in rural northern China, with a special focus on the relationship between households' economic wealth and firewood consumption. We find strong support for the poverty–environment hypothesis since household economic wealth is a significant and negative determinant of firewood consumption. Firewood can therefore be considered as an inferior good for the whole population in the rural area under study, although further evidence shows that at the top of the wealth distribution, there might be a floor effect in the decreasing firewood consumption. Besides economic wealth, our analysis also shows that the own-price effect is important in explaining firewood consumption behavior, the price effect gaining importance with rising incomes. Finally, increasing education is also found to be a key factor in energy consumption behavior, especially when dealing with energy source switching behavior.     

What causes business cycles? Analysis of the Japanese industrial production data

We explore what causes business cycles by analyzing the Japanese industrial production data. The methods used are spectral analysis and factor analysis. Using the random matrix theory, we show that two largest eigenvalues are significant. Taking advantage of the information revealed by disaggregated data, we identify the first dominant factor as the aggregate demand, and the second factor as inventory adjustment. They cannot be reasonably interpreted as technological shocks. We also demonstrate that in terms of two dominant factors, shipments lead production by four months. Furthermore, out-of-sample test demonstrates that the model holds up even under the 2008–2009 recession. Because a fall of output during 2008–2009 was caused by an exogenous drop in exports, it provides another justification for identifying the first dominant factor as the aggregate demand. All the findings suggest that the major cause of business cycles is real demand shocks.     

Sustainable natural resource use in rural China: Recent trends and policies

In this paper we provide an overview of recent trends in the availability and quality of land and water resources in rural China, and examine the common presumption that rural resources are rapidly degrading in China. Data based on consistent definitions and measurement methods that have recently become available are used to that end. In addition, we analyse the impact of new policy initiatives to introduce market-based instruments and new institutions to address land degradation and water scarcity problems.We find that the decline in cultivated area has accelerated in the beginning of the new century. Ecological recovery programs, not urbanization and industrialization, are the major factors causing this decline. Ecological recovery programs are also a major force behind the increase in forest land area and the reduction of water erosion. Modest successes can be observed in the protection of wetlands and (until the mid-1980s) for the average quality of cultivated land. On the other hand, degradation of natural grassland and wind erosion have become much more severe in recent decades.In northern China, particularly in the 3-H (Hai and Luan, Huai and Huang) river basins, the availability of water has tightened. Groundwater tables have fallen considerably in the Hai river basin, because farmers increasingly rely on groundwater for irrigation. Evidence on other parts of northern China is mixed. Pollution of surface water is getting worse since the beginning of the 1990s in two major lakes in southern China and until recently in the rivers in northern China. Water quality problems in the larger rivers in southern China are less severe and getting less. These problems are to a large extent caused by agriculture-based non-point source pollution, especially in the major lakes and reservoirs.The sloping land conversion program, water pricing, and the establishment of water user associations and payments for environmental service projects are used as cases to examine the introduction of market-based instruments and new institutions. We argue that less government interference in the implementation of these instruments and institutions is likely to enhance ecological as well the economic benefits. Moreover, supportive measures to improve the functioning of land and labor markets are usually needed to ensure the sustainability of the impact of interventions.     

Searching for an Environmental Kuznets Curve in China's air pollution

Intuitively, the concept of an Environmental Kuznets Curve (EKC) is relatively easy to understand: pollution will initially increase with economic development but then decrease again as incomes attain a certain level. The overall concept of pollution, however, actually consists of various components which may behave differently and are not easily combined into a single measure. As a result, the measurement or tracking of an EKC becomes more difficult as one tries to develop a tractable measure of pollution for modeling or policy purposes. For example, in China levels of sulfur dioxide and particulate pollution show some signs of diminishing while nitrogen dioxide levels have increased as China's auto fleet has grown. Consequently, different studies estimating an EKC often generate different results depending upon which pollutant is used and how it is measured. This paper generates composite measures of Chinese air pollution using Nemerow methodology as well as a new epidemiological index based upon the health effects of the pollutants. The paper then tests these index measures to determine whether they display evidence of an EKC and also to examine how they behave in comparison to the individual pollutants.     

Land fragmentation and farm productivity in China in the 1990s

The main objective of this study is to examine the effects of fragmentation on farm productivity in China and to discuss policy implications. Some earlier work has questioned the importance of the economic costs of land fragmentation in developing economies. It has been argued that policymakers should focus instead on reducing the root causes of fragmentation: inefficiencies in land, labour, credit, and food markets. Our results, using a more recent and larger dataset from a household survey in China, find that fragmentation does have an economic cost in China. Production functions are estimated for each of the major grain crops in the sample provinces. We also argue that to reduce the economic costs, land consolidation in China should be undertaken with less government intervention. More attention should be given to the establishment of markets for land (or land use rights) and improvements in rural credit and grain markets.     

Rural to urban land conversion in China — How large is the over-conversion and what are its welfare implications?

The current system of converting farmland to urban land use in China can be characterized as a hybrid system that combines government controls with market-based transfers. In this paper we argue that this hybrid governance structure causes an over-conversion of farmland from the rural to the urban sector, as compared to a competitive market situation, and a welfare reallocation that discriminates against farmland owners. We develop a partial equilibrium model that can be used to examine the impact of the current hybrid governance structure on the over-conversion of farmland and to analyze the welfare changes for different groups of actors and the resulting net social welfare loss. Using a dataset with detailed information on farmland acquisitions and urban land transactions in Yingtan City in Jiangxi Province, we illustrate how this framework can be applied. Our results indicate an over-conversion of 33.5% of the total converted farmland in this city between 1999 and 2003. The welfare of farmland owners affected by the conversion decreased by 1.38 billion RMB, while the net social welfare loss equaled more than 270 million RMB during the same period. The local government obtained 380 million RMB of revenues by re-selling farmland as urban land through competitive conveyance mechanisms between 2002 and 2005, while the manufacturing sector gained an estimated 280 million RMB from buying land use rights at relatively low prices. We conclude that the current policy of increasing urban land conveyance through competitive mechanisms does not address two major underlying causes of over-conversion, and that protection of farmland would be better served by replacing the current hybrid rural to urban land market structure by a competitive land market.
