PPP模式在我国森林保险经营模式创新中的应用初探

森林保险作为集体林权制度改革的一项重要配套改革内容．已经成为集体林权改革能否顺利推进、林业发展能否持续的关键。森林保险准公共物品属性导致的“市场失灵”,和林业生产经营者对于森林保险这一公共服务的需求差异性导致的“政府失灵”,决定了单一地由商业机构或政府来提供森林保险都存在弊端。所以,引入PPP模式,于适当的时机建立相对独立的“森林保险计划”,探索构建全国森林巨灾／大灾风险准备金支持下的、政府制定规则并进行监管和协助、利用商业保险公司的服务网络以及风险管理技术经办、按省进行保费统筹的公私合营森林保险模式,有利于解决森林保险的健康可持续发展问题。     

Auction versus Negotiated Sale: Evidence from Real Estate Sales

We offer a theoretical and empirical comparison of auctions and negotiated sales. We first build a simple model to show that auctions generate a higher relative price than negotiated sales when demand for the asset is strong, when the asset is more homogeneous and when the asset attracts buyers with higher valuations. Using data from property sales in Singapore, we find support for our theoretical predictions. In addition, we find that auctions do not necessarily generate a higher price premium for foreclosed properties than for nonforeclosed properties.     

On the Relative Performance of Investment‐Grade Corporate Bonds with Differing Maturities

We find that short‐maturity investment‐grade corporate bonds perform better, controlling for risk differences, than similar bonds with longer maturities. Our results are at least partially attributable to insurance companies’ trading behavior and align with the preferred‐habitat theory of the term structure. We find that insurance‐company purchases create a strong demand for long‐term bonds and that their rebalancing activity results in sales of short‐term bonds. As documented by extant literature, such demand‐supply imbalance is not easily resolved by arbitrageurs or firms seeking to time the market with bond issuance.
