THE IMPACT OF ANTI‐TERRORISM EXPENDITURE ON ECONOMIC GROWTH AND WELFARE

This paper examines the effects of increasing anti‐terrorism expenditure on economic growth rate and social welfare. It is shown that: (i) spending the least amount possible on anti‐terrorism expenditure will lead to a maximum economic growth rate; and (ii) to achieve maximum social welfare, the government should allocate its budget to anti‐terrorism expenditure. The results shed light on why the US government has chosen to uphold and pursue its anti‐terrorism policies in recent years to present day.     

ON THE IMPACT OF HETEROGENEITY ON INDETERMINACY*

Some recent research indicates that the occurrence of indeterminacy in models with externalities may be overstated because these models ignore agents' heterogeneity. We consider a neoclassical two‐sector growth model with technological externalities. Agents are heterogeneous with respect to their shares of the initial stock of capital and in labor endowments. We find that the sign of the effect of inequality on indeterminacy is not pinned down by the standard properties of preferences. However, when the inverse of absolute risk aversion is a convex (respectively concave) function, homogeneity (heterogeneity) tends to neutralize the external effects and eliminate indeterminacy.     

中国利率波动性对失业影响的研究

利率波动性是衡量利率变动整体效果的指标,从实证角度搞清楚利率波动性对失业的影响,并比较利率波动性和利率水平对失业影响的大小程度,对于货币政策调控宏观经济具有重要意义。我国利率波动性对失业的影响是反向的,并且存在一个时滞效应,只有滞后两期的利率波动性才会显著地对当期失业产生影响,这一影响要大于当期利率水平对失业的影响。利率波动性可作为我国货币政策监控的一个重要指标。     

技术进步对我国产出失业关系的影响分析

最近十几年来,我国经济出现了高增长和高失业并存的现象。可分劳动动态随机一般均衡模型模拟结果表明,技术进步促进了产出增长,同时也促进了就业增长,但对就业增长的促进作用明显小于对产出增长的促进作用,同时与技术进步相伴的资本投入也对劳动起到了替代作用。在经济活动人口不断增加的背景下,技术进步对产出和就业增长影响的不对称性,是我国高增长和高失业并存的重要原因。     

THE IMPACT OF DOMESTIC AND FOREIGN COMPETITION ON SECTORAL GROWTH: A CROSS‐COUNTRY ANALYSIS

This paper examines the impact of competition on the total factor productivity (TFP) of 21 manufacturing sectors in eighteen OECD countries over the period of time 1990–2006. We assume that the source of TFP growth can be either domestic or foreign innovation or technology transfer from the technological frontier. Trade openness, R&D, and human capital can have two effects: a direct effect on TFP (e.g., through innovation) and an indirect effect depending on the productivity gap between a given country and the technological frontier. We find that tougher domestic competition is always associated with higher sectoral productivity. Both import and export penetrations are positively associated with an increase of TFP. However, the channels through which higher TFP is materialized are different: export penetration works through level effect, while import penetration acts mainly when conditional on the level of technological development. The economical magnitude of the effect is not trivial.     

WHY DID JAPAN'S TFP GROWTH SLOW DOWN IN THE LOST DECADE? AN EMPIRICAL ANALYSIS BASED ON FIRM‐LEVEL DATA OF MANUFACTURING FIRMS*

This study analyses the cause of the slowdown in Japan's TFP growth during the 1990s. Many preceding studies, examining the issue at the macro‐ or industry‐level, have found that the slowdown was primarily due to the stagnation in TFP growth in the manufacturing sector. Using firm level panel data covering the entire sector, we investigate the causes of the TFP slowdown and find that the reallocation of resources from less efficient to more efficient firms was very slow and limited. This “low metabolism” seems to be an important cause for the slowdown in Japan's TFP growth.     

THE IMPACT OF TERRORISM AND CONFLICTS ON GROWTH IN ASIA

This paper quantifies the impact of terrorism and conflicts on income per capita growth in Asia for 1970–2004. Our panel estimations show that transnational terrorist attacks had a significant growth-limiting effect. An additional terrorist incident per million persons reduces gross domestic product per capita growth by about 1.5%. In populous countries, many additional attacks are needed to achieve such a large impact. Transnational terrorism reduces growth by crowding-in government expenditures. Unlike developing countries, developed countries are able to absorb terrorism without displaying adverse economic consequences. An internal conflict has the greatest growth concern, more than twice that of transnational terrorism. Conflict variables are associated with smaller investment shares and increased government spending, with the crowding-in of government spending being the dominant influence.     

ASSET‐BASED UNEMPLOYMENT INSURANCE*

This article studies a model of consumption, savings, and job search in which a borrowing constraint limits self‐insurance. The government administers the unemployment insurance program that may condition on an individual’s asset position, but not on her efforts of finding a job. To compensate for the impediments to self‐insurance, benefit payments should optimally be set higher at lower wealth levels and peak for borrowing‐constrained individuals with zero liquid funds. A quantitative exercise reveals that the U.S. unemployment insurance program is surprisingly close to optimal for the asset poor, but far too generous for wealthier individuals.     

NONRESIDENT POSTSECONDARY ENROLLMENT GROWTH AND THE OUTCOMES OF IN‐STATE STUDENTS

We study the effects of exposure to nonresident students on the outcomes of undergraduate in‐state students during a period of high nonresident enrollment growth at the University of Missouri‐Columbia. Our models leverage within‐major, cross‐time variation in nonresident exposure for identification. We find no evidence that increased exposure to domestic nonresidents affects in‐state student outcomes and our null results are precisely estimated. We find evidence of modest negative impacts on in‐state students when their exposure to foreign students increases using our preferred specification. However, the identifying variation in exposure to foreign students in our data is limited and this result is not robust in all of our models. (JEL I23, I28, R23)     

放松电信管制对日本移动通信市场发展的影响

本文分析了日本移动通信领域的管制改革及其对移动通信市场发展的影响。基于垄断竞争模型的分析表明,移动电话服务商的个数和移动电话服务的边际成本,是影响日本移动通信的需求和价格的关键因素。以移动通信市场自由化为目标的一系列管制改革,刺激了移动通信服务商的增加,降低了移动通信服务商的边际成本,从而促进日本移动电话通信市场的蓬勃发展。基于1991—1999年期间季度数据的经济计量模型,证实放松电信管制对移动通信服务的价格和需求量都有显著影响。此外,本文还推测了移动电话通信的需求曲线和价格弹性。     

EMPIRICAL IMPACT OF PUBLIC INFRASTRUCTURE ON THE JAPANESE ECONOMY*

We study the impact of public capital investment on individual sectors of the Japanese economy using time‐series data for the period of 1970–1998. We employ a production function approach and also estimate a dynamic VAR/ECM model. We find significant differences in the employment effects, output effects and private investment effects across sectors. Public capital investment has a positive effect on employment in the finance, insurance and real estate (FIRE), manufacturing, construction and utilities sectors; on private investment in the FIRE, agriculture, transportation, trade and services sectors; and on output in the mining, FIRE, trade and manufacturing sectors.     

THE IMPACT OF PERSONALITY TRAITS ON WAGE GROWTH AND THE GENDER WAGE GAP

This paper considers the impact of personality traits on the change of the gender wage gap. Using data from the German Socioeconomic Panel (SOEP), we first explore how personality traits affect wage growth rates. Then, a decomposition analysis is performed to analyse the dynamic effects of personality traits on the change of the gender wage gap over time. Our empirical results indicate that gender differences in conscientiousness and emotional stability lead to a widening of the wage gap over time. By contrast, gender differences in extraversion lead to a narrowing of the wage gap over time.     

ECONOMIC BENEFITS OF GLOBALIZATION: THE IMPACT OF ENTRY TO THE WTO ON CHINA'S GROWTH

A panel data method is used to evaluate the impact of China's accession to the WTO. Time‐series data for China, Australia, Austria, Canada, Denmark, Finland, France, Germany, the UK, Hong Kong, Singapore, Korea, Japan, the Philippines, Indonesia, Malaysia, Thailand, the USA and Taiwan are used to construct the growth path that what would have been followed had there been no entry by China to the WTO. We find that from 2002 to 2007, accession to the WTO raised China's real economic growth rate by 2.4%, its export growth rate by 13.2% and its import growth rate by 18.89% a year.
