探索土地问题的解决途径

从历史上看,农民的增收问题从来都是同土地产权制度的安排以及如何使用紧密联系在一起的。新中国成立以来,农地制度经历了四次重大变革。从变革中可以看出,土地问题确实是解决"三农"问题的核心。土地问题的解决不可能是一劳永逸的,现实中的问题只能通过改革来解决。

论我国农民集体土地所有权

我国农村集体土地所有权法律地位不明的一个根本原因是缺少对农村集体土地的物权制度设计,传统上对农村集体土地的公有制设计是从政治经济的意义出发的。在坚持集体土地公有制的前提下,认可集体土地所有权是民法上的私权利大有裨益,由此也有必要赋予每一个“农民集体”以法人地位,并精心设计该法人的治理结构,从而成为确保我国社会主义公有制得以实现的一种良好的方式。     

Labor unemployment risk and firm risk

This paper examines the effect of labor unemployment risk on firm risk. Using unemployment insurance benefits as a proxy for unemployment risk, we find an economically significant positive relation between unemployment risk and firm risk. This positive relation is more pronounced for firms that are more labor-intensive, have a higher layoff propensity and are more financially constrained. While existing literature that employs corporate policy measures such as debt and cash holdings suggests an opposite relationship, our paper presents evidence that the effects stemming from earnings management, earnings quality and reporting quality appear to dominate.     

乡村振兴视角下商业养老保险对土地流转影响研究

基于世代交叠理论和劳动闲暇理论以及CFPS数据,从商业养老保险的投保情况与收入情况两个层面实证分析商业养老保险对土地流转的影响。结果显示：商业养老保险一方面通过提高家庭养老保障水平的方式影响家庭参与土地流转的意愿,另一方面通过增加转移收入的方式影响家庭土地流转规模。参保商业养老保险对于土地流转意愿的影响还存在地区差异。     

Do we really care about Biodiversity?

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests to future generations.

Is Meta-Analysis a Noah's Ark for Non-Market Valuation?

This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need, the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters of a preference function with the benefitsestimates usually encountered in meta-analytic summaries.     

地价杠杆在城市经营中的调控作用——以南京市为例

本文紧密结合经营城市这个热点问题，首次系统地阐述了地价杠杆在城市经营中的重要作用。并结合南京市1998－1999年的土地出让实际工作成果，运用文中提出的观点，设立不同的口径进行详细分析与对照。通过综合分析与尝试，一方面，说明地价杠杆在政府经营城市的过程中具有不可替代的地位；另一方面，城市政府完全可以运用地价杠杆的经济特性，趋利避害，更好地促进国民经济的健康有序发展。
