Bargaining frictions, labor income taxation, and economic performance

This paper is an attempt to explain differences in economic performance between a subset of OECD countries. We classify countries in terms of their degree of rigidity in the labor market, and use a matching model with labor/leisure choice, bargaining frictions, and labor income taxation to capture these rigidity differences. Added flexibility improves economic performance in different ways depending on whether income taxation is high or low. Feeding income taxation rates estimated from the countries at hand, we find that the model is able to replicate the observed rigidity levels. The model is also shown to reproduce well cross-country differences in non-employment population ratios and the share of part-time jobs. In the absence of rigidity differences, taxation shows little promise to replicate cross-country differences, as it has insufficient quantitative effects on production and productivity. However, the interaction of rigidity and income taxation is crucial in explaining the empirical patterns of the non-employment rate and of the share of part-time jobs.     

Okun's Law Does the Austrian unemployment–GDP relationship exhibit structural breaks?

Okun's Law postulates an inverse relationship between movements of the unemployment rate and the real gross domestic product (GDP). Initial empirical estimates for US data indicate that a two to three percent GDP growth rate above the natural or average GDP growth rate causes unemployment to decrease by one percentage point and vice versa. In this investigation we check whether this postulated relationship exhibits structural breaks by means of Markov-Chain Monte Carlo methods. We estimate a regression model, where the parameters are allowed to switch between different states and the switching process is Markov. As a by-product we derive an estimate of the current state within the periods considered. Using quarterly Austrian data on unemployment and real GDP from 1977 to 1995 we infer only one state, i.e. there are no structural breaks. The estimated parameters demand for an excess GDP growth rate of 4.16% to decrease unemployment by 1 percentage point. Since only one state is inferred, we conclude that the Austrian economy exhibits a stable relationship between unemployment and GDP growth.

Agricultural technology adoption and child nutrition enhancement: improved maize varieties in rural Ethiopia

Adoption of improved crop varieties can lead to multiple benefits to farm households, including increased productivity, incomes, and food consumption. However, possible impacts of adoption on child nutrition outcomes are rarely explored in the literature. This article helps bridge this gap through an impact assessment of the adoption of improved maize varieties (IMVs) on child nutrition outcomes using a recent household survey from rural Ethiopia. The conceptual linkage between IMV adoption and child nutrition is first established using an agricultural household model. Instrumental variable estimation suggests the overall impacts of adoption on child height‐for‐age and weight‐for‐age z‐scores to be positive and significant. Quantile instrumental variable regressions further reveal that such impacts are largest among children with poorest nutrition outcomes. Finally, by combining a decomposition procedure with system of equations estimation, it is found that the increase in own‐produced maize consumption is the major channel through which IMV adoption affects child nutrition.     

深圳多功能自由贸易区的模式选择与制度设计

近年来，全球范围内的自由贸易区发展迅速，并且出现了向多功能综合型转型等新的趋势。我国各类特殊经济功能区面临着向规范的自由贸易区转型的选择。在深圳建立多功能、综合型自由贸易区，符合发展中国家自由贸易区转型的新趋势，有利于促进深港经济融合。借鉴国际自由贸易区的做法，深圳自由贸易区要建成一个规范的自由贸易区，需要对其进行科学合理的政策和制度设计。     

Globalization,Gender And The Davos Man

Using Karl Polanyi's analysis of the social construction of markets in nineteenth- and early twentieth-century Europe, the paper applies his analysis to the formation of global markets in the late twentieth century. The paper argues that Polanyi's work needs to be engendered in order to take into consideration women's and men's different links to the market and to understand the construction of "economic man" gone global. The paper also addresses the feminization of the labor force across the globe and the possible effects on women's behavior and on the construction of "economic woman." The concluding section discusses alternative interpretations of this behavior.     

我国银行和地产类股价波动性对比研究

本文通过描述性统计和建立GARCH族模型,以2008年1月2日至2013年7月11日的银行和地产类股票日收盘价数据作为样本,对我国银行和地产类股指日收益率的波动性进行了对比研究。得到以下结论：银行和地产两类股票收益率序列都是平稳的,具有“尖峰厚尾”的特点,具有波动聚集性;两类收益率的波动均具有“长期记忆性”;均存在非对称效应。     

中日韩FTA的潜在经济影响研究——基于动态递归式CGE模型的研究

区域性FTA已经成为世界贸易自由化的新趋势,中韩日FTA的构建对于3国经济融合将产生巨大的推动作用。本文首先回顾了中日韩FTA的相关研究与谈判进程;然后分析了中日韩3国的贸易结构、特征与趋势;最后,结合FTA资本聚集效应,按时间序列构建动态递归式一般均衡模型,分析了中日韩FTA对3国国内生产总值、福利(EV)、外贸进出口、贸易条件等产生的各种潜在经济影响。     

广东省良种补贴绩效分析

本文概述了广东省良种补贴政策的实施情况,对由广东省农业厅和华南农业大学经济管理学院组成的调研组在广东省内韶关、清远、梅州、河源、湛江、茂名共6个市开展的问卷调查进行分析,共回收501份有效问卷。调查结果表明农村务农劳动力中中老年人占绝对主体,农民的受教育程度偏低;农民对良种补贴政策比较满意,对其认知情况良好,希望该政策能够保持且加大力度实行;大多数农民认为良种补贴政策有利于提高自身的种粮积极性和粮食产量,并提高和稳定他们的种植收入。同时,农民也认为良种补贴政策主要存在补贴金额不足和良种补贴品种单一这两个不足之处。     

房价与经济波动的区制转移——基于STAR系列模型的实证研究

本文运用平滑转移自回归(STAR)系列模型定量分析了1998-2010年间我国经济波动区制转移(Regime Transition)过程及房价波动在其中的作用。研究结果表明,我国经济在受到外生刺激时会产生跳跃冲动,但能否出现区制转移现象取决于外生刺激的持续性,单纯依靠以往经济的表现不能充分地解释这种现象;房价作为外生变量有效地解释了经济波动中存在的动态转移过程,这表明房价波动中存在着先行信息并可用于预测未来经济走向。此外,经济波动转移过程并非不可逆转,足够的反向推动力能够扭转经济势头,这使得政策干预成为可能。
