民营企业症结及化解

中国民营企业的高速发展是有目共睹的,然而由于主客观原因,民营企业的种种弊端同样不容忽视。尤其是最近以来,许多富豪纷纷落马,将民营企业的弊端无形中放大,而媒体爆炸性炒作更是将民营企业推向被讨伐的前台。本文主要探讨民营企业发展中出现问题及其化解办法。

Points mechanisms and rewards programs

I study points programs, such as frequent flyer and other rewards programs, as a revenue management tool. I develop a two‐period contracting model where a capacity‐constrained firm faces consumers who privately learn their valuations over time. The firm cannot commit to long‐term contracts, but it can commit to allocate any unsold capacity through a points program. This points scheme creates an endogenous and type‐dependent outside option for consumers, which generates novel incentives in the firm's pricing problem. It induces the firm to screen less ex interim, and to offer lower equilibrium prices, reversing the intuition of demand cannibalization.     

A Historical Review of Postponement Research

This historical review traces the development of postponement research starting in the fifties. The focus is on seven related themes: connecting form and time postponement, conceptual extensions to postponement, decoupling points, design for postponement, customization and mass customization, factors favoring postponement implementation, and postponement in global settings. Within these themes, the review includes concepts such as postponement costs, decoupling points, part commonality, and the impact of demand correlations on the benefits of postponement. The review suggests that substantial progress has been made in postponement research.     

Effectiveness of harvest strategies in achieving multiple management objectives in a multispecies fishery

Fisheries management is characterised by multiple objectives, some of which may be complementary, while others may require trade‐offs between outcomes. Balancing these objectives is made more complex in the case of multispecies and multigear fisheries. In this paper, we develop a bioeconomic model that captures the key elements of such a fishery to test a range of potential harvest strategies to provide insights into how economic target reference points could lead to both desirable and undesirable management outcomes (e.g. discards). The model is developed as a long‐run optimisation model to identify target reference points to achieve multispecies maximum economic yield, and a dynamic recursive optimisation model, which includes more realistic representation of fishers’ behaviour, such as discards and trading of under‐caught species quotas. The potential economic, social and ecological impacts are evaluated using data envelopment analysis (DEA). The results suggest that the use of proxy target reference points can result in short‐term economic benefits at the cost of slower stock recovery and higher discarding. Limiting the number of species subject to quota controls may also prove beneficial in multispecies fisheries, while ensuring quota markets are efficient is likely to produce benefits irrespective of the harvest strategy adopted.

租金率折价视角的学区价值测度——来自上海二手房市场的证据

近年来,国内主要城市学区房现象持续升温,成为社会关注热点。由于学区房可以再出售,现有文献基于学区房溢价的研究并不能准确体现学区自身价值。本文提出租金率折价的概念,基于对上海二手房挂牌出售和出租数据的联动使用,应用特征价格模型和边界固定效应的方法对学区房的租金率折价进行系统分析,对优质教育资源的意愿支付价格做出更准确估计。实证结果表明,学区房的租金收益率平均而言比非学区房低5%,对于小户型住宅更可达19%,且租金率折价存在较大的波动,受教育部门公立学校入学政策冲击的影响大,证实学区房存在较大的政策风险。本文据此提出,实施基础教育阶段公共学校入学资格的“租买同权”,将有助于促进基础性公共教育资源的更公平利用,同时也有助于防范房地产市场价格过度波动。
