A benchmark for wage growth through the lens of the Beveridge curve

Using an estimated Beveridge curve, we trace out the vacancy–unemployment ratio in the steady state. This steady-state measure for labour market tightness is embedded in a VAR framework to obtain a benchmark for wage growth reflecting a labour market equilibrium.     

HUMAN CAPITAL INEQUALITY AND THE KUZNETS CURVE

This paper develops a Mincerian measure of human capital distribution and applies it to evaluate national and global human capital inequality and compare them with education inequality measures. It is shown that using education inequality as a proxy of human capital inequality is problematic due to the nonmonotonic relationship between them. We find that the inconsistent evidence on education and human capital Kuznets curves in the literature is due to the use of different inequality measures. In particular, human capital Kuznets curves are evident when relative inequality measures are used, whereas education Kuznets curves are found when absolute inequality measures are used. It is also observed that while global education inequality has been declining over the past four decades, global human capital inequality remains largely steady, as the decrease in between‐country human capital inequality is largely balanced by the increase in within‐country human capital inequality.     

Global slack and domestic inflation rates: A structural investigation for G-7 countries

Recent papers have argued that one implication of globalization is that domestic inflation rates may have now become more a function of “global”, rather than domestic, economic conditions, as postulated by closed-economy Phillips curves.This paper aims to assess the empirical importance of global output in determining domestic inflation rates by estimating a structural model for a sample of G-7 economies. The model can capture the potential effects of global output fluctuations on both the aggregate supply and the aggregate demand relations in the economy and it is estimated using full-information Bayesian methods.The empirical results reveal a significant effect of global output on aggregate demand in most countries. Through this channel, global economic conditions can indirectly affect inflation. The results, instead, do not seem to provide evidence in favor of altering domestic Phillips curves to include global slack as an additional driving variable for inflation.     

农业技术扩散的时间过程及空间特征分析——以陕西省苹果种植技术为例

农业科学技术只有被广大农民掌握和应用,才能转化为现实生产力,促进农业生产的发展。以陕西省苹果种植技术为例,借助"S型曲线模型"及"重力学模型"对陕西省苹果种植的时空规律进行了研究,发现陕西省苹果种植在时间序列上,其种植面积呈现在波动中上升的趋势,而在空间上,存在等级扩散与渐进扩散相结合的扩散模式,即随着空间尺度的缩减,技术扩散由明显的规模等级扩散向随距离增加扩散强度减弱的渐进式扩散转化。     

转型时期我国"产出-物价"菲利普斯曲线的动态变化趋势

笔者使用可变参数模型揭示了转型时期我国产出-物价菲利普斯曲线的动态变化趋势。研究结果表明:(1)通货膨胀率对经济增长率的反应系数均为正值,表明转型以来我国经济系统的冲击主要来自于总需求方面;(2)通货膨胀率对经济增长率的反应系数呈现凸型变动模式,并且已经过了波动的顶峰,出现显著下降并逐渐稳定的趋势,这种趋势有助于同时实现经济增长目标和稳定物价目标;(3)反映总体价格水平的价格指数不宜再作为判断宏观经济态势的指示器,但国民经济中一些重要领域的价格波动却仍然值得关注。     

长株潭城市群环境污染与经济增长的关系研究

利用长株潭城市群最近10年的经济与环境数据,建立该区域主要污染物排放与经济增长的计量关系模型。结果表明,长株潭城市群环境污染与经济增长的关系符合环境库兹涅茨曲线,除汞为U形曲线外,二氧化硫、化学需氧量、镉等其他7项指标均呈倒U形,且绝大部分指标已越过环境库兹涅茨曲线的转折点,表明长株潭城市群已进入经济与环境协调发展的有序阶段。环境政策的有力实施是促进长株潭城市群经济与环境协调发展最重要的保障。     

大掺量粉煤灰混凝土在工程中应用研究

通过试验和工程实践结舍,对高寒地区超大参量粉煤灰混凝土性能进行研究。结暴表明,掺一定量的优质粉煤友的混凝土吴有良好的施工性能、力学性能和耐久性能。为指导施工,建立了大掺量粉煤灰混凝土回弹法测强曲线经验公式,这为大掺量粉煤灰混凝土在高寒地区的应用提供了理论参考。     

我国有利于穷人的经济增长问题研究

本文以“贫困增长曲线”为理论基础,实证分析了1978-2006年来我国的经济增长是否是有利于穷人的经济增长。研充结果表明：1978-2006年间,无论对于城镇地区还是农村地区,经济增长都不是有利于穷人的经济增长;只有1978-1985年间对于城镇地区而言,经济增长才是有利于穷人的。之所以会出现这样的结果,主要原因是在经济增长的同时,我国收入分配不平等的程度不断加深,从而部分抵消了经济增长的减贫效果,使得穷人从经济增长中的获益少于非穷人。     

如何认识宏观经济与就业的关系

中国的就业体制改革和劳动力市场发育。是整体经济改革的重要方面。在这个改革过程中,形成了符合市场经济原则的政府积极就业政策体系,市场在配置劳动力资源中发挥了基础的作用。但这个改革任务还没有完成。如果宏观经济政策仅仅关注经济增长．没有真正把就业作为政策制定的出发点。不仅不能取得良好的就业扩大效果,也不能实现经济增长的初衷。在宏观经济政策选择中理解就业与经济增长和经济周期的关系,完善市场经济条件下的就业体制,实现就业与通货膨胀之间的平衡,具有十分重要的意义和紧迫性。
