International Production Networks And Changing Trade Patterns In East Asia The Case Of The Electronics Industry

The purpose of this paper is to analyze how the spread of different international production networks in East Asia has affected the trade links of the region with the U.S. and Japan. We concentrate on one particular aspect, i.e. changes in the product composition of U.S. and Japanese electronics exports and imports to and from the East Asia region. We find that compared to the U.S. , Japan’s trade links with East Asia display a far greater diversity of the product groups involved. Of equal importance is a second finding: the trade balances of both countries with the region are radically different. A consistently high and growing trade deficit characterizes U.S. trade links with East Asia in the electronic industry. This is true even for computers and components, the two sectors where the U.S. has re-established itself during the last few years as an uncontested leader. This is in stark contrast to the situation in Japan, where a large and rapidly growing surplus characterizes its trade links with East Asia. Although this is now slowly changing as East Asia has become the most important source of Japanese electronics imports, there is reason to doubt whether this positive development is strong enough to reduce any time soon the asymmetric nature of Japan’s trade links with East Asia. These differences can only be partially attributed to traditional macroeconomic factors that are the focus of standard trade theory. In the paper, we show how the observed differences can be better explained by some peculiar features of the international production networks that American and Japanese firms have established in East Asia. The chain of causation appears to work both ways. Changes in the organization of international production have led to changes in the composition of bilateral trade flows. Such changes in international trade patterns, in turn, lead to further changes in the organization of international production.international trade; international investment; economic development; business strategies; networks; Japan; USA; Asia; electronics industry

Microbubbles enhanced synthetic phorbol ester degradation by ozonolysis

A phorbol-12-myristate-13-acetate (TPA) is a synthetic analogue of phorbol ester (PE), a natural toxic compound of Euphorbiaceae plant. The oil extracted from plants of this family is useful source for primarily biofuel. However this oil might also be used as a foodstuff due to its significant nutrition content. The limitations for utilizing the oil as a foodstuff are mainly due to a toxicity of PE. Currently, a majority of PE detoxification processes are expensive as include multi steps alcohol extraction sequence. Ozone is considered as a strong oxidative agent. It reacts with PE by attacking the carbon-carbon double bond of PE. This modification of PE molecular structure yields a non toxic ester with high lipid content. This report presents data on development of simple and cheap PE detoxification process with water application as a buffer and ozone as reactive component. The core of this new technique is an application for a new microscale plasma unit to ozone production and the technology permits ozone injection to the water-TPA mixture in form of microbubbles. The efficacy of a heterogeneous process depends on the diffusion coefficient which can be controlled by contact time and interfacial area. The low velocity of rising microbubbles and high surface to volume ratio allow efficient mass transfer to be achieved during the process. Direct injection of ozone is the most efficient way to process with such highly reactive and short lived chemical. Data on the plasma unit behavior are presented and the influence of gas oscillation technology on the microbubble production mechanism has been discussed. Data on overall process efficacy for TPA degradation is shown

How ICTs Raise Manufacturing Performance: Firm-level Evidence in Southeast Asia.

This paper examines the effects of information and communication technologies (ICTs) on business performance, using firm-level data obtained through a questionnaire survey in four ASEAN countries (Indonesia, The Philippines, Thailand and Vietnam). Sources of information and new technologies exchanged via ICTs by firms are also explored to investigate the mechanism behind ICT adoption. Empirical results verify that the introduction of ICT to reorganize business processes is significantly correlated with business performance, in particular the development of export markets and improvement of production management. ICTs facilitate access to information and technologies accumulated in in-house departments and joint-venture (JV) affiliates of the respondent firms. There are considerable differences between multinational companies (MNCs)/JVs and local firms. MNCs/JVs make use of information and technologies obtainable via ICTs from their own R&D departments, JVs established with local partners and foreign-owned suppliers/customers to improve factory management, mostly for product quality improvement and production cost reduction. In contrast, local firms interconnect their own R&D departments via ICTs to enhance their business performance in broader areas than MNCs/JVs, including the development of export markets.

Item banking with Rasch Measurement: An example for primary mathematics in Thailand

This study was conducted in Thailand to create a Mathematics item bank and a Computerized Adaptive Test (CAT) for the students to ‗interrogate‘ the bank. First, 290 multiple-choice test items on mathematical equations were created for an item bank. They consisted of nine aspects: (1) identifying an equation; (2) identifying the true equation; (3) identifying equations with an unknown; (4) finding the value of an unknown that satisfies the equation; (5) identifying a method to solve an equation; (6) finding the solutions to equations; (7) finding a solution to an equation related to a given condition; (8) selecting an equation converted from a verbal problem or a verbal problem related to an equation; and (9) solving an equation problem. Seven papers with 50 items each, containing 40 different items and 10 common items, were administered to 3,062 students of Year 6 (Prathom Suksa 6). There were 409, 413, 412, 400, 410, 408, and 610 students taking part in the 1st to the 7th tests respectively. The data were analysed with the Rasch Unidimensional Measurement Model (RUMM 2010) computer program so that all the item difficulties were linked on the same linear scale along with the student measures of mathematical ability. Ninety-eight test items fitted the measurement model and were installed in the item bank. A computer program for CAT was created, tested, and modified after trialling. A controlled experiment involving the use of CAT with 400 Prathom Suksa 6 students from two primary schools in Ubon Ratchathani province, Thailand, was implemented. Thai students were very supportive of the use of CAT with the mathematical item bank. They showed an interest in CAT and in extending the use of CAT to other subject areas with appropriately developed item banks

Openness and Technological Innovation in East Asia: Have They Increased the Demand for Skills?

This paper asks whether the increased openness and technological innovation in East Asia have contributed to an increased demand for skills in the region. We explore a unique firm level data set across eight countries. Our results strongly support the idea that greater openness and technology adoption have increased the demand for skills, especially in middle income countries. Moreover, while the presence in international markets has been skill enhancing for most middle income countries, this has not been the case for manufacturing firms operating in China and in low-income countries. If international integration in the region intensifies further and technology continues to be skilled biased, policies aimed at mitigating skills shortages in the region should produce continual and persistent increases in skills.demand for skills, foreign direct investment, exports, firm level data
