THE YEN‐DOLLAR EXCHANGE RATE AND MALAYSIAN MACROECONOMIC DYNAMICS

This paper empirically assesses the effect of the yen‐dollar exchange rate on selected macroeconomic variables, namely, real output, price level, and money supply, for Malaysia. The results, which are based on a vector autoregressive framework, suggest that variations in the yen‐dollar rate can have significant influences on Malaysia's macroeconomic variables. More specifically, the yen‐dollar depreciation leads to contraction in real GDP and money supply. These results are fairly robust to alternative model specifications. We believe that, apart from providing important insights into the interactions between the yen‐dollar rate and domestic macroeconomic variables, our results contribute to the debate on choice of exchange rate regimes for Malaysia.     

RAISING EDUCATIONAL ATTAINMENT OF THE POOR: POLICIES AND ISSUES

Despite every policymaker's recognition, enrollment rates of the low‐income countries remain low. A simple framework of understanding educational outcomes is presented using a unitary model with an altruistic parent and a child. The traditional interventions, so‐called supply‐side policies, and recent innovation of relaxing constraints faced by households, the conditional transfer programs or so‐called demand‐side policies, are reviewed. In addition, recent trends on estimation technique are discussed. It has been argued that randomization is clearly the best for inference, however, one may still want to choose the optimal combination of randomized experiments and observational data, as the former requires more resources and time. This is particularly true for economics than other hard sciences, partly because of our inability to fine‐tune the control, and partly because of our lack of solid microfoundation than other sciences when an experiment shows unexpected results.     

CHILD LABOR AND SCHOOL ENROLLMENT IN RURAL INDIA: WHOSE EDUCATION MATTERS?

This paper empirically analyzes the determinants of child labor and school enrollment in rural Andhra Pradesh, India. A village fixed‐effect logit model for each child is estimated with the incidence of child labor or school enrollment as the dependent variable, in order to investigate individual and household characteristics associated with the incidence. Among the determinants, this paper focuses on whose education matters most in deciding the status of each child, an issue not previously investigated in the context of the joint family system. The regression results show that the education of the child's mother is more important in reducing child labor and in increasing school enrollment than that of the child's father, the household head, or the spouse of the head. The effect of the child's mother is similar on boys and girls while that of the child's father is more favorable on boys.     

THE POLITICAL ELEMENT IN THE WORKS OF W. ARTHUR LEWIS: THE 1954 LEWIS MODEL AND AFRICAN DEVELOPMENT

William Arthur Lewis, the Nobel Prize awardee in 1979, was actively involved in politics and policymaking. During World War II, Lewis was appointed to be a young advisor to the British Colonial Office where he came into direct collision with the mainstream laissez‐faire philosophy. After the War, Lewis took the lead in a Fabian conference on colonial question, and his encounter with Kwame Nkrumah eventually compelled him to write an important monograph on the prospect of plural governance in Africa. Through a rereading of Lewis's original texts, it is demonstrated that his emphasis on peasant‐led agricultural development and advocacy of political pluralism were consistently manifested in his academic and nonacademic writings on tropical regions, especially on Africa, contrary to the conventional interpretation of his 1954 model of “Economic Development with Unlimited Supplies of Labour,” which has tended to pin much faith on top‐down industrialization.     

THE IMPACT OF GREEN REVOLUTION ON RICE PRODUCTION IN VIETNAM

The current paper reviewed the development of the Green Revolution in Vietnam, using long‐term regional yield and modern variety adoption statistics, as well as household data collected in 1996 and 2003. The present study indicates that the Green Revolution began in irrigated favorable areas and spread to the less favorable areas in Vietnam such as in other Asian countries. What is unique in Vietnam is that although the Green Revolution ended in the mid‐1980s in the Philippines and Indonesia, it has still been sustained as of 2003. Our analyses revealed that such growth had been supported by continuous improvements of modern varieties by regional research institutes. The varieties imported from China have contributed to the Green Revolution in northern Vietnam and those developed by the International Rice Research Institute in southern Vietnam. The national agricultural research systems have also played a critically important role in developing location‐specific and appropriate technologies.     

ADOPTION AND PRODUCTIVITY IMPACT OF MODERN RICE VARIETIES IN BANGLADESH

Technological progress has helped Bangladesh to achieve self‐sufficiency in rice production in 2001 from a heavy import‐dependence, despite doubling of population and a reduction in arable land since its independence in 1971. As the adoption of modern varieties (MV) of rice is reaching a plateau, particularly for the irrigated ecosystem, an important issue is whether the research system will be able to sustain the growth of production. The present paper addresses the following questions: (i) to what extent farmers have been replacing the old MV with the new MV, and (ii) what has been the impact of the variety replacement on productivity and profitability. How crucial is the continuous research and release of improved rice varieties toward improving farm production and income for farmers comes out as a clear message to policymakers from the current paper.     

Does Foreign Direct Investment Affect the Growth of Local Firms？ The Case of China＇s Electrical and Electronics Industry

Does foreign direct investment(FDI) into developing countries affect the growth of local firms in host countries? Using a dataset of 38 sectors in China’s electrical and electronics industry,in this paper,we analyze whether FDI has a positive effect on local firms,with technology spillovers,added value and increasing total factor productivity,or a negative, market stealing,effect.Estimating the relationship between growth of local firms and investment of foreign firms,our results show that FDI is likely to have a negative impact on the growth of local firms in sectors with large disparities in technology and less experience in business.Therefore,local firms lacking in technology need to find markets with no competition from foreign firms or determine strategies to compensate technology disparities.     

Local Officials＇ Incentives and China＇s Economic Growth： Tournament Thesis Reexamined and Alternative Explanatory Framework

To explain China's dramatic economic growth, researchers have proposed a “tournament thesis.” According to this thesis, the central government's ability to set growth targets has played a crucial role in growth since political promotion is largely based on local economic growth. We use provincial officials' career mobility data to test this thesis. For both time periods (1979–1995 and 1979–2002), economic performance, measured in annual, average and relative terms, did not affect these officials' career advancement. We then sketch an alternative analytical framework to explain Chinese local officials' strong urge for developmentalism and, finally, draw policy implications from this explanatory framework.     

华北地区某污水处理厂升级改造工程实例

华北地区某城市污水处理厂升级改造工程处理规模为50万t/d,原设计为A/O脱氮工艺,执行《城镇污水处理厂污染物排放标准》(GB 18918-2002)二级排放标准。由于近年来进水水质严重恶化以及对污水排放标准的提高,需对原污水处理系统进行改造,通过技术方案对比,在原生物处理段增加厌氧池,使之变为A2/O脱氮除磷,新增深度处理工艺为反硝化生物滤池-加砂沉淀池-滤布滤池-紫外消毒,使出水水质达到一级A排放标准。     

The Influence of a Credit Rating Change on Dividend and Investment Policy Interactions

We examine firms’ alterations in dividend and investment activities following credit rating changes. We find that downgraded firms reduce both dividends and investments more than no‐rating‐change firms. However, a silver lining of this doubly negative impact for shareholders is an increase in investment efficiency in firms that are most likely to overinvest. For upgraded firms, investments increase, but dividend outlays do not, compared to firms without rating changes. Our findings of asymmetric dividend stickiness and symmetric investment changes on a credit shock suggest that dividends and investments should not always be considered competing uses of funds.
