Has Labor Income Become More Volatile? Evidence from International Industry‐Level Data

Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry‐specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross‐sectional heterogeneity is substantial. If anything, the labor incomes of high‐ and low‐skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear‐cut impact.     

经济法视野中的商业秘密侵权探索

随着商品经济的发展,商业秘密的重要性越来越引起人们的关注,商业秘密的侵权行为也不时地困扰着商业秘密的合法拥有者。商业秘密侵权行为严重损害了商业秘密所有人的合法利益,破坏了公平竞争的社会秩序,制止商业秘密侵权已成为我国法制社会建设的重要任务和使命。     

Thailand-Japan＇s Volume of Trade Influencing on Socio-economic and Well-Being Development Using Maximum Entropy Bootstrap

This paper is preliminary information on some empirical findings based on an analysis of Thailand＇s macroeconomic data. The purpose of the study is to quantify social-economic well-being development with special emphasis on poverty. The maximum entropy bootstrap was presented that did not require the property of stationarity. Moreover, the methodology was stratified both the ergodic theorem and the central limit theorem. Thailand＇s GINI index and Thailand-Japan＇s volume of trade data cover the 14-year period from 1998 to 2011. There is a statistically significant negative non-linear relationship between endogenous Thailand＇s GINI index and exogenous Thailand-Japan＇s volume of trade. The results confirmed that every lagged one percent increase in Thailand-Japan＇s volume of trade influenced by a decrease of Thailand＇s GINI index coefficient 0.039 percent with the asymmetric around 0-almost closed to range condition -0.034824348 at 2.5%.     

A Classroom Tariff-Setting Game

The author outlines a classroom tariff-setting game that allows students to explore the consequences of import tariffs imposed by large countries (countries able to influence world prices). Groups of students represent countries, which are organized into trading pairs. Each group's objective is to maximize welfare by choosing an appropriate ad valorem tariff that may be changed intermittently throughout the game. The game is built on a computable general-equilibrium model, which allows each nation's utility and terms of trade under alternative tariff regimes to be expressed quantitatively. The exercise encourages students to consider terms-of-trade improvements and efficiency losses resulting from large-country tariffs and provides a framework to discuss the Nash equilibrium of a tariff war. The game is a useful supplement to traditional teaching methods.     

公允价值计量模式下所有者权益问题探讨

所有者权益计量是否准确、真实,不仅影响股东的权益,而且还决定它提供的会计信息是否有用。实际中我们发现,在现行的公允价值计量模式下,会计计量的所有者权益与股权价值相差较大,本文针对这一问题进行了分析,并提出相应的解决方法。     

The consumption-real exchange rate anomaly with extensive margins

This paper investigates a consumption-real exchange rate anomaly from the open macroeconomics literature known as the Backus-Smith puzzle. We both analytically and quantitatively examine how an expansion of trade along extensive margins can contribute to the puzzle's resolution. Our argument is based on 1) a wealth effect due to changes in the number of product varieties, 2) statistical inefficiency in measuring the number of product varieties, and 3) market incompleteness. Contrary to complete asset markets which, in general, feature overly strong risk sharing properties, changes in the number of product varieties under incomplete markets may produce a wealth effect under high trade elasticity. Since statistical agencies systematically fail to capture the welfare impact arising from that changes, data-consistent terms of trade and real exchange rates tend to appreciate due to this positive wealth effect. This provides a realistic correlation between data-consistent real exchange rates and consumption.     

对EMU启动前后欧盟国家贸易状况的实证研究

EMU的启动对EMU成员国、欧盟其他国家甚至全世界都有着很大的影响。但是在EMU启动至今已十年,它是否真的发挥了它应有的作用?为了研究这个问题本文选取了对EMU成员国贸易情况进行实证研究的角度来透视EMU启动所带来的影响。本文选取了1992～2007年的面板数据,并通过扩展引力模型实证检验了EMU对其成员国贸易的影响情况。本文研究结果表明:从整体上而言,EMU对其成员国的贸易影响是正面的,即:EMU的实施增加了EMU成员国与其它国家的双边贸易,但对于不同国家EMU的影响具有差异性。     

黑龙江省对俄贸易发展存在的问题及对策研究

目前,黑龙江省在对俄贸易、投资、经济技术合作等方面取得巨大成绩的同时,还存在着一系列急需解决的问题：对俄贸易企业的整体实力不强;进出口商品结构单一;商品货物贸易层次较低;出口产品技术含量低;缺乏本省名牌产品;市场贸易秩序与服务贸易体系不健全等,影响和制约了对俄贸易的进一步发展。促进对俄贸易的发展,必须转变外贸形式,优化贸易产品结构,着力打造本土企业品牌,提高商品技术含量,拓展能源原材料投资合作领域。同时,坚持＂以俄为主、注重日韩、兼顾其他＂的原则,大力开拓国际市场,从而促进黑龙江省对外贸易快速发展。

Trade and Specialisation in Pollution Intensive Industries: North–South Evidence

Abstract

The pollution haven hypothesis (PHH) and the capital-labour hypothesis (KLH) state that the relative level of a country's environmental regulations and capital and labour endowments determines its comparative advantage respectively. Since these hypotheses lead to conflicting predictions as to whether the North or the South will specialise in pollution-intensive production, this paper examines whether changes in trade and specialisation patterns allow us to distinguish between pollution haven and factor endowment effects. We employ a methodology that enables us to present North-South trade patterns over time and to identify those periods when trade patterns were consistent with either the PHH and/or the KLH as a foundation for undertaking more detailed econometric studies.
