Private polling in elections and voter welfare

We study elections in which two candidates poll voters about their preferred policies before taking policy positions. In the essentially unique equilibrium, candidates who receive moderate signals adopt more extreme platforms than their information suggests, but candidates with more extreme signals may moderate their platforms. Policy convergence does not maximize voters' welfare. Although candidates' platforms diverge in equilibrium, they do not do so as much as voters would like. We find that the electorate always prefers less correlation in candidate signals, and thus private over public polling. Some noise in the polling technology raises voters' welfare.     

Hurdle and Latent Class Approaches to Serial Non-Participation in Choice Models

In repeated choice modelling studies, it is often the case that individuals always select the status quo option. Although this pattern may reflect considered choices, they may also be the result of alternative decisions about whether to participate in the choice process at all. Alternative methods of dealing with this behaviour, each with associated implications for estimates of economic values, are presented. In particular we consider the alternative strategies of excluding such individuals from the data, using hurdle models to explicitly model this group, and propose the use of latent class models to endogenously allow for different preference structures. An advantage of the latent class approach is that the form of the non-participation need not be defined in advance. These approaches are considered using UK choice experiment data on food choices where the attributes include genetic modification of food. The latent class approach reveals the presence of two forms of non-participation in the data. This paper draws work commissioned by UK Department of Environment Food and Rural Affairs (DEFRA). The views presented in this paper are those of the authors alone and should not be regarded as those of DEFRA or of individuals within DEFRA.     

基于BIM的工程项目成本核算理论及实现方法研究

对建设项目而言,预算超支现象十分普遍。而缺乏可靠的成本数据是造成成本超支的重要原因。建筑信息模型(BIM)作为一种变革性的生产工具将对建设工程项目的成本核算过程产生深远影响,能有效提高建筑生产过程成本计算的可靠性。首先分析了建筑信息模型对成本计算过程的影响,提出了3种基于BIM的工程项目成本计算的技术方案,并详细分析了每种技术方案的特点,最后,对基于BIM的成本计算过程中的一些关键问题进行了分析和讨论。     

1994-2007年我国经常项目变动特点及原因分析

自1994年起,我国经历了持续的贸易顺差与自主性国际收支的总体顺差。国际收支经常项目呈现出良好的盈余态势、对国际收入平衡的贡献增大等特点,其原因是由于我国产业竞争力提高,国家政策扶持,储蓄、汇率等因素刺激造成的。     

Agglomeration spillovers and wage and housing cost gradients across the urban hierarchy

The tyranny of distance in terms of its effect on median earnings and housing costs is examined for rural and urban U.S. counties. First, we develop a series of distance metrics for an area's remoteness from multiple tiers of the urban hierarchy. Second, we consider geographical access of buyers and sellers through market potential measures typical of those used in empirical studies of the New Economic Geography. We estimate penalties of about 5 to 9% for median earnings and 12 to 17% for housing costs for area remoteness from the combined tiers of the urban hierarchy. Differences in market potential also influence factor prices, but these effects generally are smaller than those produced by urban hierarchy distances. Thus, it appears that empirical tests of New Economic Geography models need to consider sources of agglomeration spillovers beyond aggregate market potential.
