影响失地农民再就业的原因分析与政府作为

失地农民再就业一直是党和政府着力解决的"三农"问题之一。从消除制度缺陷、提供培训资金支持、拓宽非农产业就业渠道、搞好就业培训等方面采取的措施尚未见到实效。失地农民再就业受到收入水平、生活成本、工作环境、技能要求、地区经济发展等因素的影响,政府应当在注重产业布局和调整的同时适度保留劳动密集型产业、加大公共财政保障力度,强化用人单位培训责任、系统设计失地农民权益保障制度等方面入手,破解失地农民"被城市化"后的再就业困境。     

谷书堂关于社会主义商品经济理论的探索

The role of complementarity and partner brand price level in new product introduction strategy using bundle offers: A study on the quality perception of bundle components

The quality perception of a new brand improves when it is bundled with a product having a strong brand image, moderated by the level of complementarity between the bundle components. This study takes this research forward with the help of two experiments. The first experiment uses anchoring and adjustment process to conclude that the quality perception of a new brand further strengthens if bundled with a strong brand of a higher price category than itself. The second experiment concludes that the quality perception of the strong brand can also deter if bundled with a new product of uncertain quality.     

ARBITRAGE‐FREE BILATERAL COUNTERPARTY RISK VALUATION UNDER COLLATERALIZATION AND APPLICATION TO CREDIT DEFAULT SWAPS

We develop an arbitrage‐free valuation framework for bilateral counterparty risk, where collateral is included with possible rehypothecation. We show that the adjustment is given by the sum of two option payoff terms, where each term depends on the netted exposure, i.e., the difference between the on‐default exposure and the predefault collateral account. We then specialize our analysis to credit default swaps (CDS) as underlying portfolios, and construct a numerical scheme to evaluate the adjustment under a doubly stochastic default framework. In particular, we show that for CDS contracts a perfect collateralization cannot be achieved, even under continuous collateralization, if the reference entity’s and counterparty’s default times are dependent. The impact of rehypothecation, collateral margining frequency, and default correlation‐induced contagion is illustrated with numerical examples.     

地方财政行为是否驱动了中国贸易 收支的动态调整*——基于异质性动态调整模型的分析

本文利用1997-2013年中国省际层面的面板数据，借助异质性动态调整模型从动态视角考察了地方财政行为对中国贸易收支调整速度的影响。研究结果显示：（1）平均而言，在地方财政行为的驱动下，中国实际贸易收支向最优水平动态调整的速度约为0045。总体表明，地方财政行为对中国贸易收支的驱动性影响较弱，引致实际贸易收支向最优水平调整的速度也较为缓慢。（2）财政支出分权的强化会制约贸易收支的调整速度，贸易收支调整呈现“相对惰性”。财政收入分权的提高和预算内财政支出的扩张能够加快实际贸易收支向最优贸易收支调整的速度，助力贸易收支实现平滑调整。预算外财政支出和财政收入的变化对调整速度则不会产生显著性影响。（3）贸易收支的调整速度呈现显著的区域异质性。本文的结论表明，现阶段中国要实现贸易收支的平衡调整路径，中央及地方政府必须把握好财政行为与贸易收支的动态联动关系。     

Do stock markets discipline US Bank Holding Companies: Just monitoring,or also influencing?

This paper presents evidence that bank managers adjust key strategic variables following a risk and/or valuation signal from the stock market. Banks receive a risk signal when they exhibit substantially higher (semi-)volatility compared to the best performing bank(s) with similar characteristics, and a valuation signal when they are undervalued relative to the average bank with similar characteristics. We document, using a partial adjustment model, that bank managers adjust the long-term target value of key strategic variables and the speed of adjustment towards those targets following a risk and/or negative valuation signal. We interpret this as evidence of stock market influencing. We show that our results are unlikely to be driven by indirect influencing by regulators, subordinated debtholders, retail or wholesale depositors. Finally, we show that the likelihood that banks receive a risk and/or valuation signal increases with opaqueness, managerial discretion and specialization.

Can Federal Grants Mitigate Social Competition?

The European economic integration leads to increasing mobilityof factors, thereby threatening the stability of social transferprograms. This article investigates the possibility to achieveby means of voluntary matching grants both the optimal allocationof factors and the optimal level of redistribution in the presenceof factor mobility. We use a fiscal competition model a la Wildasin(1991) in which states differ in their technologies and preferencesfor redistribution. We first investigate a simple process inwhich the federal authority progressively raises the matchinggrants to the district choosing the lowest transfer and alldistricts respond optimally to the resulting change in transfersall around. This process is shown to increase efficiency ofboth production and redistribution. However, it does not guaranteethat all districts gain, nor that an efficient level of redistributionis attained. Assuming complete information among districts,we derive the willingness of each district to match the contributionof other districts and we show that the aggregate willingnessto pay for matching rates converges to zero when both the efficientlevel of redistribution and the efficient allocation of factorsare achieved. We then describe an adjustment process for thematching rates that will lead districts to the efficient outcomeand guarantee that everyone will gain. (JEL Classification:H23, H70)     

德国公共养老金调整指数改革研究

1957年德国首先建立了基于总工资指数的养老金调整指数,该指数运行34年后,面对人口老龄化的加剧,进行了多次改革。其改革的根本原因在于:基于养老金指数化调整的公共养老金计划缴税率不断攀升及由此对市场效率产生了严重负面影响。一个国家选择何种养老金调整指数取决于本国国情、经济发展状况等因素,但不能忽视调整指数对市场效率的影响,应坚持"效率优先,兼顾公平"的原则。作为发展中国家,中国在设计养老金调整指数时,坚持这一原则更为重要。
