需求冲击与通货膨胀——基于中国的经验研究

通过使用2005年1月至2007年12月的月度数据,借助向量自回归模型,分析了需求因素对近期中国通货膨胀冲击的影响.研究结果显示:需求冲击是中国本轮通货膨胀压力上升的重要原因.其中,投资需求和消费需求对通货膨胀率上升的影响作用明显,而净出口对通货膨胀率上升的影响并不显著.因此,抑制总需求过快增长.将是控制物价上涨、保持宏观经济稳定的重要途径.

Globalized Horticulture: The Formation and Global Integration of Export Grape Production in North East Brazil

In horticulture contemporary globalization is associated with (at least) two connected processes – the concentration, centralization and expanding reach of global retailers and the emergence of numerous new sites of export horticulture specializing in fresh fruit and vegetable production aimed at metropolitan markets. Whilst there have been numerous studies about developmental impacts, conditions of labour, and producers' upgrading strategies within this new context, few studies give much, if any, space to explaining and analyzing the processes through which these new regions have come into being. This article provides a detailed account of the emergence and global integration of one of these new sites – the São Francisco valley grape branch in North East Brazil, within the context of the wider regional fruiticulture sector. It focuses on state activities and incentives, the provenance of grape producers and their organizations, and grape branch composition.     

Land Reform in South Africa

An insightful study of the complexities of land reform in South Africa is reviewed, and its key arguments assessed. The study astutely combines ethnographic and historical detail from in-depth case studies in Mpumalanga Province with critical analysis of land reform policies, and locates these within larger theoretical debates on property rights, citizenship and identity. The author argues that a profound and unresolved tension exists within South Africa's land reform programme between broad and inclusive conceptions of 'rights' that are linked to notions of restored citizenship and sovereignty, and a conception of 'property' as individualized ownership of land, implying a much narrower conception of citizenship. The study also focuses on the roles of a variety of mediators and 'brokers' in land reform. Despite its many strengths, the study is not entirely convincing, partly because some key policy debates are mischaracterized. Its treatment of questions of agricultural production, rural livelihoods and the political economy of agrarian change is somewhat disappointing.     

Inflation and Welfare: A Search Approach

This paper uses a search model of monetary exchange to provide new insights for evaluating the welfare costs of inflation. We first show that the search model of money can rationalize the estimates of the welfare cost of inflation based on the "welfare triangle" methodology of Bailey (1956) and Lucas (2000) provided that buyers appropriate the social marginal benefit of their real balances. For other mechanisms, the measure given by the welfare triangle has to be scaled up by a factor that increases with sellers' market power. We introduce capital and endogenous participation decisions and study how the cost of inflation is affected. We provide calibrated examples in which a deviation from the Friedman rule is optimal.     

Do Hedge Funds Manipulate Stock Prices?

We provide evidence suggesting that some hedge funds manipulate stock prices on critical reporting dates. Stocks in the top quartile of hedge fund holdings exhibit abnormal returns of 0.30% on the last day of the quarter and a reversal of 0.25% on the following day. A significant part of the return is earned during the last minutes of trading. Analysis of intraday volume and order imbalance provides further evidence consistent with manipulation. These patterns are stronger for funds that have higher incentives to improve their ranking relative to their peers.
