The impact of agricultural technology adoption on income inequality in rural China: Evidence from southern Yunnan Province

This study analyzes the impact on income inequality of government efforts to increase agricultural incomes in rural China. It collects and analyzes survey data from 473 households in Yunnan, China in 2004. In particular, it investigates the effects of government efforts to promote improved upland rice technologies. Our analysis shows that farmers who adopted these technologies had incomes approximately 15% higher than non-adopters. Despite this relatively large increase, we estimate that the impact on income inequality was relatively slight. This is primarily due to the fact that lower-income farmers adopted the improved rice technology at rates that were roughly equivalent to those of higher-income farmers.     

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.     

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.     

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.     

Technological choice of Chinese rice farmers

This paper investigates the technological choice followed in China's rice production, using primary farm household survey data collected in 1994. Drawing on the modelling procedures used by Lin (1991), the empirical testing done in this paper fails to confirm the hypothesis of induced technological choice, the well known Hicks-Hayami-Ruttan-Binswanger hypothesis. The analysis reveals that Lin's formulation may under certain circumstances lead to odd results when looking at cross section data. As an alternative specification, this study proposes cost shares in the place of physical quantities while modelling the production process. Empirical results using our suggested specification clearly confirm the hypothesis of induced technological choice.     

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.     

China''s land arrangements and rural labor mobility

Chinese farm families under the Household Responsibility System have the land use-rights but not the rights of alienation. If permanently leaving agriculture, they have to return the land to local authorities and consequently give up a stream of future land earnings. This paper analyzes the deterrent effect of this land arrangement on labor mobility by constructing a household model which considers both part-time farming and permanent migration decisions. The implications of the model are consistent with the recent Chinese experience of rural floating population in cities and the rapid growth of rural nonagricultural employment.     

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.     

China's grain marketing system reform in 1993–1994: empirical evidence from a rural household survey

By utilizing a rural household survey, this paper domonstrates the progress in China's grain marketing reform in 1993 and evaluates to what extent the reform was reversed in 1994. Specifically, we investigate the degree of commercialization, changes in state's contract procurement quota and changes in the marketing channels. Overall, the grain market has been liberalized to a very large extent. Participation of the private traders have already grown to a significant level, occupying more than one-third of the market share for wheat and rice and more than half for maize. For minor crops, the share of private traders were even bigger. Despite the reversal in 1994, the grain market was still very “open.” Counting all grain types, the state was controlling only about one-third of the marketed surplus. However, if the central leadership perceived any serious instability in the market for a certain grain, examples provided illustrate how the state's control could certainly be strengthened significantly.     

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.     

Decomposition of the increase in earnings inequality in urban China: A distributional approach

This study examines changes in Chinese urban income distribution from 1987 to 1996 and 1996 to 2004 using nationwide household data and investigates the causes of these changes. The Firpo, Fortin, and Lemieux (2007, 2009) method based on unconditional quantile regressions is used to decompose changes in income distribution and income inequality measures, such as variance and a 10:90 ratio. The decomposition results show that wage structure effects, such as a widening gender earnings gap, increases in returns to college education, and increases in earnings differentials between industries, company ownership types, and regions, have been the major contributors to the overall increases in income inequality. It was also found that at different points on the income distribution (e.g., the lower or upper half), the contributing factors that increase income inequality are different.     

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     

Chinese wool auctions: Failed agribusiness reform or future marketing channel?

The spectacular though short-lived operation of China's wool auctions graphically illustrates problems in reforming China's agribusiness sector. A selective coverage of product type and participants, a highly contrived process of price discovery, and an urgent need for parallel reform in related areas all led to the demise of the auctions and are a barrier to their re-emergence as a viable wool marketing channel. Despite the challenges facing wool auctions, this paper argues that they still have much to offer the marketing of wool in China.     

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.     

A politically feasible social security reform with a two-tier structure

This paper investigates the welfare implications and political feasibility of social security reforms with a two-tier structure in Japan. We evaluate social security reforms from two points of view: (i) the ex-ante expected value of future generations, and (ii) whether current generations prefer reform to the status-quo system, which we call political feasibility. To evaluate the reforms, we use a large-scale overlapping generations model with idiosyncratic income risk and a two-tier structure. The first tier guarantees a basic pension and the second tier consists of the earnings-related part. Calibrating the parameters of the model to the Japanese economy, we compute the transition path and the two welfare criteria. We find that, given the two-tier structure in Japan, an increase in the basic pension and the abolition of the earnings-related part of the social security system improve the welfare of future generations, and ensures political feasibility when a consumption tax is the source of revenue.     

A political economy analysis of the Korean economic crisis

This paper analyzes the causes of the Korean economic crisis from a political-economic perspective. The author points out that the economic causes which had been mentioned often such as overvalued won exchange rate and moral hazard of financial sector and corporate sector, have political origins. If the Korean economic crisis was caused by political economic factors, structural reform of the economy alone is not sufficient for economic recovery. Therefore, this paper argues, the behaviors of politicians, bureaucrats, and interest groups had been influential for resource allocation in the Korean economy. It concludes that the self-interest seeking activities of various interest groups should be properly controlled.     

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.     

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.     

The usefulness of earnings versus book value for predicting stock returns and cross corporate ownership in Japan

Using a sample of Japanese firms, this paper evaluates the usefulness of the two fundamental products of an accrual accounting system, namely accrual earnings and book value of equity for predicting stock returns. Our analysis shows that both earnings and book value for Japanese firms have the ability to provide for profitable trading strategies or improved portfolio decisions, and that relative to the trading strategy based on earnings or book value alone, the trading strategy based on a combination of both earnings and book value generates substantially higher returns for all cases. This suggests that book value (or earnings) captures certain aspects of equity values that are not captured by earnings (book value). Our multivariate regression results further indicate that the predictive ability of earnings is dominated by that of book value. Finally, it is found that the predictive ability of book value is sensitive to the degree of cross corporate ownership, while it is insensitive to the degree of real estate holding.     

Income inequality in central Spain, 1690–1800

This paper studies the evolution of income inequality in central Spain during the late seventeenth and eighteenth centuries, taking as case study the province of Guadalajara. The first part of the paper presents the sources and the dataset that was created to estimate income inequality using grain tithes. The second section shows that through the period grain represented the lion share of total income and therefore that it can be used as a reliable proxy. The following part of the paper introduces an analysis of income inequality in the province during the period 1690–1800 and concludes that inequality decreased during the last third of the eighteenth century. Finally the paper addresses this unexpected result and concludes that it was consequence of the success of the land reform carried out by the central government in the late 1760s. The reform was a success in Guadalajara, thanks to the characteristics of its population and the lack of bargaining power of pressure groups.
