精准扶贫背景下农村资金投入与农民收入增长研究

本文采用时间序列数据对财政支农支出与农民收入之间的关系进行了实证研究。 结果显示财政支农资金对农村居民收入产生了显著的正面影响;财政支农结构中,支援农业生 产支出对农民收入的影响最大,然后依次是农业基本建设支出和农村救济费,而农业科技三项 费用对农民收入的影响不显著。综合考虑财政对三农、教育、健康的投入的研究结果显示,国 家在健康方面的投入对农村居民纯收入的正面影响最大,其次是对“三农”的支出,农村居民 的受教育水平对农村居民的纯收入的影响为负,但对农村居民的经营性纯收入和工资性纯收入 的影响为正。在此基础上,结合国家精准扶贫背景,本文建议应继续加大财政对“三农”的支 持力度,同时重视对农村健康和教育方面的投资,在健康与教育之间,应该优先选择提升农村 居民的健康水平。     

中小企业融资难的新解读

中小企业融资难问题已成为制约我国市场经济体制改革的重要因素。对主要发达国家经验的梳理,可以得到解决该问题的一般规律。基于我国中小企业发展的特点、金融系统结构失衡、政府职能错位三个方面的解读,可以发现我国中小企业融资难问题具有特殊性。本文提出的建议,包括构建"银政合作"模式,推进金融体制改革,创建中小型金融机构。     

考虑干扰风险影响下应急物流仓储量最优模型分析

传统模型在处理应急物流仓储量时,存在抗风险弱、误差大的缺陷,容易出现混乱,无法进行有效的调度,不能满足及时的应急物流需求。为了解决这一问题,提出一种考虑干扰风险影响下的应急物流仓储量最优模型,模型使用仓储量方案优化指标体系层次结构,分析不同的干扰风险因素,获取最佳的仓储量控制方案,通过立体物流仓储模型获取仓储货位的有效货物量,采用微粒子优化算法对立体物流仓储模型进行优化求解,获取最佳的仓储量。仿真实验结果表明,该模型能够准确描述不同的干扰风险,具有较高的仓储量优化效率和较低的误差率。

Disclosure of Downside Risk and Investors' Use of Qualitative Information: Evidence from the IPO Prospectus's Risk Factor Section

I use the context of a company's initial public offering (IPO) of equity securities as a capital‐market setting to empirically study the economic consequences of risk factor disclosures. Using data from Australian IPOs, I examine the relation of textual risk disclosures in the prospectus to initial underpricing. I find that the quantity of disclosures in the risk factor section itself has no significant impact on initial underpricing. However, an increase in the informativeness of risk factor disclosures is associated with lower IPO underpricing. My results suggest that IPOs that provide informative risk factor disclosures have less ex ante uncertainty, in the sense that the disclosures help investors estimate the dispersion of secondary market value. The effect of informative risk factor disclosures on IPO underpricing is more pronounced for IPOs with less prestigious lead underwriters and is mainly driven by younger firms, smaller firms, and firms with poorer operating performance prior to their IPOs. Collectively, my findings suggest that informative disclosures of downside risk are useful for investors to evaluate IPOs.     

Systemic risk and dynamics of contagion: a duplex inter-bank network

This paper constructs a duplex banking network formed by credit relationships and information interaction via the banks’ balance sheet to model the structure of systemic risk and investigate the dynamic mechanism of contagion in terms of default and liquidity infection along with the factors that affect the extent of the contagion. We systematically explain the role that duplex banking networks play in different aspects of risk contagion. Through theoretical analysis and simulations, we conclude that asymmetric information interaction would increase the inflexibility of the system, which leads to liquidity shortage and possibly the collapse of the whole market. The weakness of systemic risk in the interior of the complex banking system can be characterized by the partial discount factor using illiquid assets in the information network. By improving the connectedness of the information network of the duplex networks, the spread of contagion can be partially slowed.     

Prizes and lemons: procurement of innovation under imperfect commitment

The literature on research and development contests implicitly assumes that contestants submit their innovation regardless of its value. This ignores a potential adverse selection problem. The present article analyzes the procurement of innovations when the procurer cannot commit himself to never bargain with innovators who bypass the contest. We compare fixed‐prize tournaments with and without entry fees, and optimal scoring auctions with and without minimum score requirement. Our main result is that preventing bypass is more costly in the optimal auction, and the optimal fixed‐prize tournament is more profitable than the optimal auction.
