高管团队特征、薪酬激励对内部控制质量影响的实证研究——来自创业板上市公司的经验数据

近年来我国在内部控制建设方面成就显著，根据高层梯队理论和委托代理理论，内部控制的建设需要高管团队的执行，而高管的行为又会受到激励制度的影响，鉴于此本文以2010～2013年创业板173家上市公司为研究对象，实证检验了创业板上市公司高管团队特征及薪酬激励与内部控制质量之间的关系。高管特征方面，高管团队规模与内部控制质量成正相关。薪酬激励方面，高管的薪酬规模、持股比例与内部控制质量正相关。本文丰富了高管特征及薪酬对内部控制质量影响的研究成果，对于我国创业板内部控制制度的建设有现实的指导意义。     

Financial Analysis of Scale Versus Lump Sum Timber Sale Payment Methods

A financial analysis of two methods commonly used by public land management agencies to collect payment for stumpage sold was carried out using data from the St. Louis County Minerals and Land Department (SLCMLD) in northern Minnesota. The two payment methods evaluated were scale (also called pay-as-cut and consumer scale) where the buyer only pays for timber harvested and lump sum (also called sold-on-appraised-volume or SOAV) where a buyer pays for the entire tract’s estimated volume, regardless of the amount of timber actually harvested. The analysis found no significant difference in gross timber sale revenue collected by the SLCMLD under the two payment methods Scaled timber sales incurred an additional $323 in administrative costs per timber sale compared to lump sum timber sales. This increase in administrative costs represents less than 1% of the timber value contained in the average SLCMLD timber sale. Differences in the standards agencies use to estimate merchantable stand volume of a timber sale and the administrative time spent processing timber sales can impact the financial costs associated with each timber payment method.     

Measuring heterogeneity,survey engagement and response quality in preferences for organic products in Nigeria

The identification of the market potentials of organic products is important in the drive towards a sustainable agricultural development in sub-Saharan Africa (SSA). However, available evidence shows that valuing attributes of credence goods (such as organic products) while using stated preference methods faces additional obstacles compared to other normal goods. In this study, we examine consumers’ preferences and willingness-to-pay (WTP) for health and environmental attributes of organic products in Nigeria. We employ an approach that allows us to adequately capture the value of organic products by linking part of the heterogeneity across respondents to differences in scale, while making use of indicators of survey engagement, without risks of endogeneity bias and measurement error that arise from the deterministic methods. The empirical results show that market for organic products exists in Nigeria, with reduction in pesticide residues attribute attracting the highest value, followed by the certification programme. Furthermore, we observe that increases in the latent engagement variable lead to a greater probability of agreement with statements relating to survey understanding and realism, and hence more substantive output.     

An integrated indicator system for patent portfolios: evidence from the telecommunication manufacturing industry

Against the background of ‘patent portfolio races’ in industries such as telecommunications, this paper proposes a set of patent portfolio indicators to measure patents’ scale and diversity. This indicator system is used in a time series to analyse the patenting activity and technology strategy of the world’s top 20 firms in the telecommunication manufacturing industry, based on a large data set from United States Patent and Trade Office. In combination with composite and relative measures, we identify the firms’ comparative positions in patenting activity. The paper adds to the ongoing discussion about, and enriches the theory of, patent portfolios.     

Modeling and Promoting Organic Food Purchase

This study aims at enhancing organic food product (OFP) purchase by identifying customer segments based on their knowledge and attitude related to organic food along with their demographic profile. Two scales for measuring Knowledge and Attitude related to organic food were developed to measure their levels. The scales have covered six dimensions of organic food: Healthy, Eco-friendliness, Price, Availability, Certification, and Brand. After identifying the customer segments, each segment was further segmented based on their media consumption behavior. Hierarchical followed by K means cluster analysis resulted to six distinct segments with their corresponding subsegments. Cluster analysis was again performed for each customer segment, and a media selection method (MSM) was evolved to effectively communicate with OFP customers. These methods can guide marketers in devising an appropriate communication plan for enhancing OFP purchase.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Box-Jenkins方法在我国沿海规模以上港口货物吞吐量预测中的应用

影响港口运输的因素多而复杂,且货物吞吐量的时间序列往往不平稳,如果通过找出影响港口货物吞吐量的因素变量,并建立回归模型进行分析,往往会存在自变量构造技术上的困难以及产生虚假回归问题等等。因此,本文采用时间序列分析中的Box-Jenkins方法对我国沿海规模以上港口货物吞吐量进行建模及预测,其结果表明运用Box-Jenkins方法建模预测能大大减小误差,提高预测的精确性,从而为合理制定我国港口的发展战略提供条件。     

Why Cities? A Response

Why do cities exist? Geographers Allen Scott and Michael Storper recently put the question before the field of urban studies and provided a clear and concise answer in terms of economies of agglomeration and the urban land nexus. I argue that two other basic elements must be added to this duo: the spatial concentration of economic surplus by ruling classes and states and the creation of a built environment or urban landscape. In addition, I take issue with Scott and Storper's neglect of the problem of scale in urban theory and their overly tidy sense of what constitutes a scientific approach to complex phenomena like cities.     

Errors of misclassification in discrimination of dimensional coherent elliptic random field observations

The problem of classification of dimensional coherent elliptic random field observations into one of two populations specified by different regression mean models and common stationary scale matrix is considered, under the further assumption that the observations to be classified are dependent on the training samples. In this statistical frame, the behaviour of linear discriminant function is studied and an asymptotic expression for the distribution function of the probabilities of misclassification is derived.
