海洋资源资产分类与核算框架研究

海洋作为国家的基础和战略资源,是国家重要的生存财富与保障,开展海洋资源资产分类与核算框架研究是挖掘海洋资源的市场价值,集约高效调控海洋开发管理活动的基础前提。本文分别从法律与经济两个层面剖析自然资源类别,并综合资源和资产双重属性,将海洋资源划分为海洋生物资源、海洋矿产资源、海洋空间资源与海水资源四大类,并进一步深入探索海洋资源资产核算框架,构建海洋资源资产核算表式结构与价格评估方法,最终从产权制度、用途管制、有偿使用与生态补偿4个方面为海洋资源资产化管理提出了探索方向。     

Income comparisons and attitudes towards foreigners - Evidence from a natural experiment

We exploit a natural experiment related to the German re-unification to address whether disutility from income comparisons affects attitudes towards foreigners. Our empirical approach rests upon East German individuals with West German relatives and friends. We use the exogenous variation of wealth of West Germans shortly after the fall of the Berlin Wall as an instrument to identify the effect of disutility from income comparisons on East Germans’ attitudes. We find robust evidence that East Germans express more negative attitudes towards foreigners, particularly from low-wage countries, if they worry about their economic status compared to better-off West Germans.     

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation

Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision.     

Natural resource dependence, non-tradables, and economic growth

I argue that the commonly used nominal measure of natural resource dependence – the share of exports of primary products in GNP – understates in growth regressions the negative link between natural resource dependence and per capita GDP growth. I show that using a purchasing power parity adjusted measure yields an economically much larger negative relationship between per capita GDP growth and natural resource dependence than what has been suggested by the nominal measure. Consistent with the rent-seeking literature, I show that the resource curse is a symptom of societies characterized by high levels of corruption and sluggish checks and balances on political decision-making.     

苏里格气田建设中的管理模式创新与技术创新

天然气是"绿色能源",21世纪是天然气能源的世纪。加快我国最大的气田——苏里格气田的勘探开发建设进程,是推动我国天然气工业发展的重要战略举措。在开发建设中,秉持"科技、绿色、和谐"的理念,通过技术与管理创新,形成了12项开发配套技术,探索出了"5 1"合作开发模式,创建了"六统一,三共享"管理机制,并全面推行"标准化设计、模块化建设、数字化管理",最大限度地保护了环境。苏里格气田规模有效开发的配套技术与管理体系,对国内类似油气田的开发建设具有普遍的启示意义。     

人口、资源与环境经济学结构框架的生产视角分析

本文从生产的视角勾画了人口、资源与环境经济学的结构框架.通过对生产过程、生产要素的分析,揭示了人口、资源、环境与经济系统的内在联系;在人口、资源、环境经济大系统中分析了人口生产系统、资源环境生产系统和经济生产系统的生产目的及其相互关系;人口、资源与环境经济学应该实现对来自人口的人力资源、来自生态系统的自然资源和来自经济系统的人造资源三种生产性资源的有效配置,实现人与自然的协调发展.     

The Eisner Puzzle,the Unemployment Threshold and the Range of Equilibria

Using a two-regime model of the inflation-unemployment process for US data 1960:2 to 2000:2, this paper finds strong evidence to support the Eisner puzzle, which occurs when the short-run Phillips curve (SRPC) is flatter at low rates of unemployment than at higher rates. The puzzling aspect of this pattern is the expectation of excess demand to become apparent at very low rates of unemployment causing the SRPC to be steep rather than fairly flat. We show the puzzle can be resolved by estimating a three-regime model which reveals a steep SRPC at very low rates of unemployment. The estimates of the three regime model also reveal a horizontal SRPC at intermediate rates of unemployment, implying the existence of a range of equilibrium rates of unemployment at those intermediate rates.

EVALUATION OF CONTINGENT REPAYMENTS IN MICROFINANCE: EVIDENCE FROM A NATURAL DISASTER IN BANGLADESH

Frequent and strictly scheduled repayments and savings in microfinance often deteriorate the liquidity of members in the face of negative shocks. Previous articles suggest the introduction of a contingent repayment system that allows such members to be rescheduled, but the unavailability of a suitable dataset makes it difficult to examine how it would actually work. This study is one of the first to evaluate the impact of this repayment system on household livelihood. In employing a unique dataset from Bangladesh, I show that rescheduling reduces the possibility of binding credit constraints and borrowing from moneylenders, and may also reduce transitory poverty. However, short‐term rescheduling has insignificant effects. Indebted members with less liquid assets are more likely to be rescheduled.     

论我国生态补偿机制的确立

近年来我国西部地区自然灾害频发,并再次引发人们对西部地区发展的关注。建立生态补偿机制,使西部地区因生态保护而做出的牺牲能获得合理补偿,不仅是公平原则的具体体现,而且有利于西部经济社会的持续发展。
