从价值论出发比较《资本论》与西方经济学

马克思的《资本论》与西方经济学,由于价值论上的本质区别,因而演绎出不同的理论体系。在论述工资、利润、地租及历史观时,二者既存在对象上的关联性,又得出了对立的结论。在我国社会主义市场经济改革进程中,一方面要坚持《资本论》的指导地位,不断丰富和发展马克思主义理论;另一方面又要借鉴和利用西方经济学中的合理成分,为改革实践拓宽道路。     

二代继任方式、家族权威与家族企业创新投入

代际传承背景下家族企业创新投入是家族企业治理研究领域的重要问题。分析和检验了差异化二代继任方式如何影响家族企业创新投资水平,以及二者关系是否会依赖于家族权威差异而发生变化。研究结果发现：与渐进型二代继任相比,激进型二代继任会削减家族企业创新投入;二代继任方式与家族企业创新投入关系受到家族权威的影响。在家族成员权威和非家族创业元老权威较重的企业,激进型继任者对家族企业创新投入的削弱效应更显著。进一步研究发现,二代继任3年后,激进型继任者对家族企业创新投入的负面影响显著下降,且其削弱效应在规模较大企业以及创立时间较长的企业中更显著。

重庆旧城改造区土地覆被与景观格局变化——以北碚区为例

以重庆市北碚区为例,以2001、2006和2011年三个时期的土地利用变更调查数据库数据为基础数据,借助GIS技术,对旧城改造区的土地利用/覆被与景观格局进行分析,结果表明:2001—2011年的10年期间,区域始终以农用地为主要覆盖类型,一级农用地变化幅度不大,农用地下的二级地类发生较大转变,其他农用地向林地及园地发生大幅转化,主要原因是北碚规划建设生态型新城区;建设用地不断增加,到2011年达到区域18.03%占有量,建设用地主要由未利用地转化而来;2001—2011年,区域景观破碎度呈现由小破碎度到大破碎度再到小破碎度的趋势,到2011年破碎度达到最小值;区域各地类的分维数呈现增加趋势,说明自然景观受人为因素的影响越来越大。     

Giffen goods and market making

Summary. This paper shows that information effects per se are not responsible for the Giffen goods anomaly affecting traders demands in multi asset noisy, rational expectations equilibrium markets. The role that information plays in traders strategies also matters. In a market with risk averse, uninformed traders, informed agents have a dual trading motive: speculation and market making. The former entails using prices to assess the effect of error terms; the latter requires employing them to disentangle noise traders demands within aggregate orders. In a correlated environment this complicates the signal extraction problem and may generate upward sloping demand curves. Assuming (i) that competitive, risk neutral market makers price the assets or that (ii) uninformed traders risk tolerance coefficient grows unboundedly, removes the market making component from informed traders demands rendering them well behaved in prices.Received: 30 April 2002, Revised: 3 December 2003, JEL Classification Numbers: G100, G120, G140.Support from the Barcelona Economics Program of CREA and the Ente per gli Studi Monetari e Finanziari Luigi Einaudi, are gratefully acknowledged.

The effectiveness of government spending on education and health care in developing and transition economies

Recent studies show that corruption is associated with higher military spending [Eur. J. Polit. Econ. 17 (2001) 794] and lower government spending on education and health care [J. Publ. Econ. 69 (1998) 263]. This suggests that policies aimed at reducing corruption may lead to changes in the composition of government outlays toward more productive spending. However, little empirical evidence has been presented to support the claim that public spending improves education and health indicators in developing and transition countries. This paper uses cross-sectional data for 50 such countries to show that increased public expenditure on education and health care is associated with improvements in both access to and attainment in schools, and reduces mortality rates for infants and children. The education regressions are robust to different specifications, but the relationship between health care spending and mortality rates is weaker.     

Do stock market returns predict changes to output? Evidence from a nonlinear panel data model

Recent empirical work suggests a predictive relationship between stock returns and output growth. We employ quarterly data from a panel of 27 countries to test whether stock returns as useful in predicting growth. Unlike previous research, our approach allows for the possible non-linear effect of recessions on the growth-return relationship. There is strong evidence to suggest that a linear model would be misspecified and provide potentially misleading inference. Using a switching regression approach, we find evidence that returns are most useful in predicting growth when the economy is in recession.First version received: November 2002/Final version received: April 2003This paper benefited greatly from discussions with Kalvinder Shields, Mark Harris, Pete Summers, and Vance Martin.
