Human capital accumulation in the East Asian NiCs has also been quite rapid. As shown in table 1-2 above, over the past two and a half decades the proportion of the working population with a secondary education or more doubled in Hong Kong and Taiwan, tripled in Korea and quadrupled in Singapore. By 1990/1991, some 18% to 20% of the working population in each economy had some tertiary education. In weighting labour input by sex, age and educational haracteristics(discussed further below), I have found that the improving educational attainment of the workforce contributes to about 1% per annum additional growth in labour input in each of these economies All of the influences noted above, rising participation rates, intersectoral transfers of labour, improving levels of education, and expanding investment rates, serve to chip away at the productivity performance of the East Asian NICs, drawing them from the top of Mount Olympus down to the plains of Thessaly. In a companion paper (Young 1993), I use simple back of the envelope calculations and large international data sets to show that, as regards productivity growth in the aggregate economy and in manufacturing in particular, the NiCs cannot be considered to be strong outliers in the post-war world economy. This paper concentrates on a more careful analysis of these four economies, making use of the extensive statistical record embodied in their national accounts, population censuses, and sectoral, wage and labour force urveys methodology. Sections II-VI then provide a country by country analysis of aggregate ang on The remainder of this paper is organized as follows: Section I presents a short review sectoral total factor productivity growth. Section Vil contrasts this research with earlier work on Defined as junior college and above in Korea and Taiwan and matriculation/a levels and above in Hong Kong and singapore
