On the benefits of party competition

We study the role of parties in a citizen-candidate repeated-elections model in which voters have incomplete information. We first identify a novel “party competition effect” in a setting with two opposing parties. Compared with “at large” selection of candidates, party selection makes office-holders more willing to avoid extreme ideological stands, and this benefits voters of all ideologies. We then allow for additional parties. With strategic voting, citizens benefit most when the only two parties receiving votes are more moderate. With sincere voting, even with three parties, extreme parties can thrive at the expense of a middle party; and whether most citizens prefer two or three parties varies with model parameters.

Codes of ethics in the light of fairness and harm

Nine codes of ethics from companies in the Swedish financial sector were subjected to a content analysis to determine how they address and treat employees. The codes say a great deal about employee conduct and misconduct but next to nothing about employee rights, their rightful expectations or their value to the firm. The normative analysis – echoing some of the value‐based HRM literature – draws on the foundational values of respect, equality, reciprocity and care. The analysis shows that most of the codes are in conflict with these values. Such a treatment is then in conflict with fairness and risks harming the employees. Some of the features that make these codes ethically problematic are typical of how corporate codes have been described in previous code studies. Consequently, the normative analysis reaches beyond the scope of this material and in the end, what is at stake, is a very typical code design.     

布什的货币金融政策

布什执政期间美联储先后有传奇人物格林斯潘和学术精英伯南克担任理事会主席一职。美国的货币政策可分为13次连续降息、17次连续升息和相对稳定3个时期,其经济也从最初的低迷走到了长期经济稳定增长,甚至面临着通货膨胀和经济危机的风险。本文试从经济、政治、执行等不同角度分析布什任期美国货币金融政策调整的原因。     

基于LINGO优化的灰色模型在旅游需求预测中的应用

提出了一种基于LINGO优化的灰色模型（简称LINGOGM），并将LINGOGM模型运用于桂林市的旅游需求预测。与传统的GM（1，1）模型相比，LINGOGM模型在旅游需求预测中具有较高的预测精度和较广的应用范围。     

Stochastic inflation and government provision of indexed bonds

This paper examines the consequences of using indexed bonds as one of the government financing instruments, along with money and taxes. It is shown that open market operations between money and indexed bonds do not matter in a real sense despite their different risk characteristics. Increasing the share of indexed bonds in the government portfolio increases the volatility and the conditional mean of real rates of return on money. When provided by means other than open market operations, indexed bonds can affect the allocation of resources, but these reallocations cannot be Pareto-improving.

基于竞价上网的煤电纵向一体化及其效率

煤电矛盾的根源是价格双轨制和地区生产不对称性，纵向兼并能有效解决现阶段煤电矛盾，但一体化是否有反竞争效应却值得商榷。本文通过纵向兼并交易的博弈模型，研究电力竞价上网背景下，存在上下游纵向兼并的煤电交易行为均衡路径及其效率，认为煤电纵向兼并的竞争效应与反竞争效应并存，但如果煤炭可现货交易，竞争效应大于反竞争效应。文章最后提出了相应的政策建议。
