Further Analysis of the Zipf's Law: Does the Rank-Size Rule Really Exist?

The widely-used Zipf’s law has two striking regularities. One is its excellent fit; the other is its close-to-one exponent. When the exponent equals to one, the Zipf’s law collapses into the rank-size rule. This paper further analyzes the Zipf exponent. By changing the sample size, the truncation point, and the mix of cities in the sample, we found that the exponent is close to one only for some selected sub-samples. Small samples of large cities alone provide higher value of the exponent whereas small cities introduce high variance and lower the value of the exponent. Using the values of estimated exponent from the rolling sample method, we obtained an elasticity of the exponent with respect to sample size. We concluded that the rank-size rule is not an economic regularity but a statistical phenomenon.Zipf's law; Rank-size rule; Rolling sample method

Property Tax in Urban China

This paper examines the urban housing sector of China and proposes a property tax reform. Over the past decade, housing price in urban China has been increasing dramatically because of strong demand for self-use, investment and speculation. The booming housing market, however, has brought several challenges for further development, such as housing affordability, inequality, and possible housing bubble. One strategy is to reform the current property tax system. Specifically, this paper proposes that China significantly reduces taxes in circulation but levies property tax during possession. Doing so will increase housing affordability because of lower transaction costs, reduce speculation because of higher cost of holding, stabilize fiscal system because of more sustainable tax revenues, and improve the efficiency and fairness of the property tax system because of the implementation of “ability-to-pay” and “who use who pay” principles.Property tax; China

Urban Poor in China: A Case Study of Changsha

Since the late 1970s, many state-owned enterprise employees have been laid off and more and more rural people have migrated to urban areas. In this massive laying-off and migration process, many laid-off workers and migrants have become urban poor. Using data collected from a survey on 1641 relatively low-income households in Changsha in January 2007, this paper compares migrant workers with their city counterpart regarding income, employment, education, and social support. Based on qualitative and regression analysis, we found that worker’s age, Hukou status, education, enterprise ownership, and contract length are significantly affecting the annual income. There exists a big gap in the coverage of social security between urban and migrant workers. This paper provides some policy recommendations.Urban poor; Hukou; Laid-off workers; Migrant workers; Income determinants; Social insurance

Industrial Upgrade, Adverse Employment Shock and Land Centralization

Traditional Development Economics defines economic development in the view of transferring rural surplus labor force. It implies the industrialization is in a static state at a certain level while it is in a process of continuous industrial upgrade in reality. Under the circumstances, we analyze phenomenon followed by the upgrading of industrial structure such as return migration and mid-aged rural labors’ difficulty in job-hunting and demonstrated the influence of land centralization based on the practice of industrial upgrade and rural change in Suzhou. Finally it come to the conclusion that because of the extensive competition on simple-labor market, the industrial upgrade will make a adverse employment shock upon mid-aged rural labor which will lead to the more uncertainty of peasants to get jobs in the industrial section . If government takes an improper policy of land centralization, peasants will lose guarantee in the future and resist the land centralization. After the comparison between one-off compensation and land cooperation, a further demonstration show that the method of one-off compensation will depress peasants’ enthusiasm in land centralization while the form of land cooperation can guarantee and promote peasants’ welfare under the given institution of land ownership. As a result, land cooperation allows the smooth operation of land centralization and supports the industrial upgrade to some extent.Over-confidence，Regional Government Competition，Redundant Construction，Yangzte River Delta

Paradoxes of Traffic Flow and Economics of Congestion Pricing

This paper utilizes a unique county-level dataset to examine technical efficiency and technology gap in China’s agriculture. We classify the counties into four regions with distinctive levels of economic development, and hence production technologies. A meta-frontier analysis is applied to the counties. We find that although the eastern counties have the highest efficiency scores with respect to the regional frontier but the northeastern region leads in terms of agricultural production technology nationwide. Meanwhile, the mean efficiency of the northeastern counties is particularly low, suggesting technology and knowledge diffusion within region might help to improve production efficiency and thus output.China’s grain production; County-level; Metafrontier; Stochastic production frontier; Technical efficiency

Tenders with Different Risk Preferences in Construction Industry

Underlying the fact that different tenderers have different preferences on risk-taking, this study investigates the different tenderers' behaviors in one-shot construction bid auctions. Our model extends the preconditions of previous assumption that all tenderers are characterized by neutral risk-taking in the original tendering model for lowest-price sealed tender. A general tendering model for the lowest-price sealed tender is established to explain the behavior of tenderers during the tendering. The results indicate that construction estimate is affected by the degree of uncertainties in the construction industry. Therefore, in a lowest-price sealed tender, risk-averse tenders would tender a higher price and conversely risk-seeking tenderers would tender a lower price when risk-neutral tenderers would tender a middle price. However, the risk-seeking tenderers are more likely to win the bid.Auction, tender, uncertainty, preference, construction industry

Industrial Upgrade, Employment Shock and Land Centralization in China

This paper investigates the relationships among industrial upgrading, mid-aged peasants’ non-farm employment, and land conversion systems. We prove that China’s efforts to upgrade its industries generate a negative employment shock on mid-aged peasant workers, forcing some of them to return to their home villages. The current lump-sum land acquisition system, however, will neither help peasant workers deal with the adverse employment shock nor promote land centralization for industrial and urban uses. On contrary, land cooperation, an emerging land centralization system, will help peasant workers mitigate the adverse employment shock and centralize rural land for nonagricultural purposes.Peasant workers; Industrial upgrade; Employment; Land centralization

Mobility of the Chinese Urban Poor - A Case Study of Hefei City

In a rapid economic development environment with rising income, escalating motorization, and growing urbanization, it is natural for government policies to focus on solving congestion related problems caused by the increased car ownership and usage. The mobility needs of the urban poor have been traditionally neglected in policy and in practice, particularly in developing countries. This paper addresses the mobility challenges the urban poor are facing based on a household travel survey in the City of Hefei in China. It first presents travel behaviors, transportation costs and commuting problems of the urban poor. It then discusses the urban transportation policy implications and examines the prevailing trends of urban transportation policies and plans in Chinese cities. Policy recommendations are suggested to improve the mobility needs of the urban poor.Urban transportation, poverty, mobility
