SECTORAL ELASTICITY OF SUBSTITUTION AND RETURNS TO SCALE IN SOUTH AFRICA

Elasticity of substitution and returns to scale are estimated on a sectoral basis for South Africa using panel-based generalised least square procedure. Apart from sectoral differences in terms of elasticity of substitution, the study found that elasticity of substitution is below unity in all of the sectors. Most of the sectors studied are found to have increasing returns to scale in production. The study further explores the implications of elasticity of factor substitution and returns to scale on growth and employment creation. It is argued that a greater number of jobs can be created from growth of sectors with constant or decreasing returns to scale than from the same level of output growth generated by sectors with increasing returns to scale. This is the case when the employment-creating potential of the same amount of additional output is compared in all the sectors examined. By virtue of scale economies, a sector like finance, insurance, real estate and business services generates more output with less proportional increase in inputs, which means growth in this sector may not have the desired impact on job creation. However, given the sector's large share (20%) of the country's total output and employment, it may generate more jobs, even if sectors like utilities and construction experience the same level of output growth. Given its importance for growth and employment, the study recommends further investigation into the reasons why elasticity of substitution is lower in sectors like utilities, mining and trade, catering and accommodation services.     

Immigrant Specificity and the Relationship between Trade and Immigration: Theory and Evidence

Studies routinely document that immigrant employment concentrates in non‐traded goods sectors and that many immigrants have low inter‐sectoral mobility. We consider these observed characteristics of immigrant employment with regard to the question of how immigration affects a nation's pattern of production and trade. We model an economy producing three goods; one is non‐traded. Domestic labor and capital are domestically mobile but internationally immobile. Allowing that some new immigrants will become specific to the non‐traded goods sector, the model indicates that the effects of immigration on output and trade depend importantly on the sectoral pattern of employment of both new and existing immigrants. Empirical investigation in a panel data set of OECD countries supports the model's prediction that immigration raises the output of non‐traded goods. Consistent with the model, we also find that immigration and trade are complements. Given its empirical support, the model's implications for immigration policy are then discussed.     

China,Like the US,Faces Challenges in Achieving Inclusive Growth through Manufacturing

For more than three decades the goal of becoming “the factory of the world” has been at the core of China's development strategy. This strategy, in combination with high rates of domestic investment and low rates of consumption, has made Chinese production the most manufacturing intensive in the world. But as its wages have risen, China's competitiveness in the most labor‐intensive manufacturing industries has eroded. Its ability to assemble products remains a major source of its exports, but it has also tried to shift toward more sophisticated value‐added production domestically. Chinese domestic spending has shifted away from investment toward consumption as citizens' income has grown. Like Americans, Chinese are also spending more on services than on manufactured goods. All of these changes are fundamentally altering the structure of China's production, reducing the role of manufacturing and increasing the skill levels of workers in manufacturing. This paper reviews the challenges posed by these developments for China's long‐term goal of achieving more inclusive growth. It presents evidence that the commonly held perceptions that Chinese manufacturing employment growth is robust are wrong. In fact, such growth has peaked and China is now following a pattern of structural change that is typical of a more mature emerging economy, in which the share of employment in manufacturing declines as workers are increasingly employed in services.     

Economic spillover effects in the Bohai Rim Region of China: Is the economic growth of coastal counties beneficial for the whole area?

This study uses panel data on the Bohai Rim Region of China to test for spatial autocorrelation, and measures economic spatial spillover effects with the space Durbin econometric model. We discuss whether the economic development of coastal counties benefits the whole area. To do this, we focus on the “distance from the coast” factor, which is influenced by transportation time. The results indicate the presence of significant spatial autocorrelation in the Bohai Rim Region. Further, economic spatial spillover effects exist in this region. “Distance from the coast” exerts a significantly negative impact on the local GDP per capita but a significantly positive impact on the GDP per capita of other districts. This means that the economic development of coastal counties does not benefit the whole region. “Value of exports” exerts a significantly positive influence on the local economy and no significant influence on other counties, while “foreign direct investment” exerts a significantly positive influence on the local economy and a significantly negative influence on other counties. “Number of employees in units” exerts a significantly positive influence on the local economy and a significantly negative influence on the other counties. The factors “primary industry's share in GDP” and “tertiary industry's share in GDP” influence the local economy positively, but the former exerts no significant influence on other counties and the latter exerts a negative influence on other counties. “Rate of fixed asset investment” influences the local economy negatively and has no significant effect on other counties. “Total retail sales of social consumer goods” has no significant influence on the local economy but a positive significant influence on the others. Finally, marine resource utilization and marine output can affect economic growth positively. On this basis, we propose policy suggestions for harmonious economic development in this region.     

SAVING IS NEVER A CONSTRAINT ON INVESTMENT1

Saving is regarded in mainstream macroeconomics as a volitional relationship, like consumption. This paper argues that this view is incorrect. There is no independent volitional saving function. Since all goods produced are either consumption goods or investment goods, saving, defined as “income not consumed”, is the accounting record of investment spending. Changes in the definition of investment produce identical changes in saving, with no accompanying volitional change in saving behavior. “Saving” in economics should properly be termed “abstention” since it does not constitute transitive behavior. To understand saving behavior a Hicksian definition of income must be used, and capital gains and losses must be included in the definition of income. In modern capitalist economies most saving undertaken by agents is non‐volitional, and takes the form of permitting the market value of total net wealth to increase.     

DETERMINANTS OF SECTORAL COMPOSITION IN A SMALL OPEN ECONOMY: THEORETICAL AND QUANTITATIVE INVESTIGATIONS OF THE PHILIPPINES

The Philippine economy since the 1980s has undergone shifts of production, employment, and consumption in the direction of the greater share of nontradable sectors, despite relatively stagnant economic growth. This paper examines sources of the sectoral shifts theoretically and quantitatively based on a dynamic model of a small open economy. The theoretical analysis identifies possible factors affecting the evolution of the sectoral composition: changes in sectoral total factor productivity (TFP), the tariff rate, and the terms of trade. Then, the relative importance of these factors is examined quantitatively by conducting simulations of the model calibrated to the Philippine economy.     

Physical capital accumulation in Asia 12: Past trends and future projections

The pace of capital accumulation in East Asia has simply been stunning. In this paper, we investigate sources of this fast accumulation and make projections for the future. We estimate a “convergence” equation for physical capital per capita, which is derived from an open economy growth model, using a pooled cross-country, across-decade sample of the entire world. We also conduct projections for the next two decades. We find that an economy with a low level of capital stock per capita tends to experience faster accumulation subsequently. Asian economies have certainly benefited from this “convergence effect”. But on the other hand, other factors such as a low rule of law score and high investment goods prices have worked against them. Our projection shows that, if those economies wish to maintain their current pace of fast capital accumulation, the keys would be to reduce distortions in the domestic market and to improve the quality of institutions.     

Regional cooperation and the environment: Do “dirty” industries migrate?

Regional Cooperation and the Environment: Do “Dirty” Industries Migrate? — This article develops an alternative method to investigate trade in embodied environmental factor services (EEFS) and applies it to bilateral trade between APEC economies. The issue of regional cooperation and the environment is addressed by investigating trade in EEFS between APEC economies in the last three decades. We observe a ‘cascading’ pattern in net exports of EEFS between East Asian economies. However, we do not observe a similar pattern in the trade between North American economies. The results should be interpreted with caution since the application of US sectoral pollution intensity data to other countries may lead to biased estimation of trade in EEFS.     

Zambia at 50: The persisting challenges of economic structural transformation

This article examines the structural transformation trajectory in Zambia since independence. Drawing from sectoral analysis of the structure of output and the composition of labour over the last five decades, the article illustrates that although there have been shifts in the composition of output and labour in the economy, especially since 2000, these shifts have not contributed to positive structural transformation. Instead the economy has been experiencing widening productivity gaps between sectors, signalling perverse economic structural transformation. Although there have been some slight improvements in the overall productivity since 2000, productivity in the agriculture and informal sectors, where almost 85% of the labour works, has remained stagnantly low. This is compounded by the economy experiencing a net movement of labour from high to low-productivity employment, mainly the informal urban sector.     

International trade and net investment: theory and evidence

The theory of welfare accounting shows that comprehensive measures of net investment can be used to test whether an economy is following unsustainable paths of consumption. However, the notion of net investment used in most applied studies rules out technological progress and terms-of-trade gains from international trade. This paper considers an augmented expression of net investment derived from a dynamic growth model featuring international trade in different types of resource inputs, exogenous productivity growth in final sectors, and cost-reducing progress in resource extraction. Calculating augmented net investment for the world’s top twenty oil producers, we show that the difference with standard non-augmented measures can be large and may even revert some established conclusions regarding sustainability: prospects are more favorable than previously thought in oil-exporting countries endowed with large reserves like Angola, Azerbaijan, Kuwait, Saudi Arabia and Venezuela. In oil-importing economies, future consumption possibilities are limited by the lack of expected rental incomes from future resource exports.     

Dynamic comparative advantage and the welfare effects of trade

Developing economies may face a trade-off between specializingaccording to existing comparative advantage (in low-technologygoods), and entering sectors in which they currently lack acomparative advantage, but may acquire such an advantage inthe future as a result of the potential for productivity growth(in high-technology goods). Comparative advantage is endogenouslydetermined by past technological change, while simultaneouslyshaping current rates of innovation. Hence, specialization accordingto current comparative advantage under free trade may be welfarereducing. Selective intervention may be welfare improving, bothfor the economy undertaking it, and for its trade partner.     

Population dynamics and economic growth in China

This paper focuses on two major elements of China's population dynamics—the rising proportion of workers in the population and the shift of rural workers from agriculture into industry and services—in a provincial-level analysis of per capita income and productivity growth during the last three decades. We measure the ‘mechanical’ contributions of these dynamics to per capita income as revealed by growth decompositions, before assessing the determinants of per capita income and productivity growth in a series of regressions that include the growth of the working-age to total population (WAP) ratio and a measure of sectoral employment change. Our results indicate that sectoral change has made a significant positive contribution to both per capita income growth and aggregate productivity growth, stemming from its positive impact on agricultural productivity growth—as predicted by the Lewisian dual economy model. However, the negative impact of sectoral change on productivity growth in the industrial and service sectors, combined with the negative impact of growth of the WAP ratio on both per capita income and aggregate productivity growth, suggests that the benefits of China's population dynamics during the last three decades have been overstated.     

Trading away what kind of jobs? Globalization,trade and tasks in the US economy

Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets in developed and developing countries. Classical models of globalization and trade, based upon the international exchange of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual production tasks. This fragmentation, captured in the growing volume of intra-industry trade, prompts investigation of the effects of trade within, rather than between, sectors of the economy. In this paper we examine the relationship between international trade and the task structure of US employment. We link disaggregate US trade data from 1972 to 2006, the NBER manufacturing database, the Decennial Census, and occupational and task data from the Dictionary of Occupational Titles. Within-industry shifts in task characteristics are linked to import competition and technological change. Our results suggest that trade has played a major role in the growth in relative demand for nonroutine tasks, particularly those requiring high levels of interpersonal interaction.     

The factor income distribution in China: 1978–2007

This paper investigates changes in aggregate labor share in China during 1978 and 2007 with a particular focus on the 1995–2007 period during which official statistics report a drop of 12.45 percentage points in labor's share of national income (labor share). Our main findings are: (1) The reported fall in aggregate labor share is overstated. According to the official statistics released by the NBS (2007a), the labor share fell 5.25 percentage points from 2003 to 2004. However this dramatic decline, 42.16% of the total reported decline of the labor share from 1995 to 2007, is completely due to the changes in the way NBS break down the operating surplus state-owned and collective-owned farms and the mixed income of the owners of individual economy; (2) For the last three decades, two main forces have been driving shifts in the aggregate labor share: (i) structural transformation between the agriculture and non-agriculture sectors and (ii) shifts in the labor share within the industry sector; (3) From 1995 to 2003, these two effects are both negative and together drive down aggregate labor share by 5.48 percentage points. The structural change explains 61.31% of the decline and the remaining 38.69% of the decline is due to the changes in the labor share within sectors, primarily in the industry sector; (4) Labor share in agriculture is lower than labor share in services. Therefore, when the service sector grows relative to the agriculture sector in the economy, the aggregate labor share of income declines; and (5) Restructuring of the SOEs and expanded monopoly power are the main reasons for the decline of labor share within industry after 1998. Relative price shifts, the factor input ratio, and biased technological progress are all insignificant forces for this decline because the substitution between factors in the industry sector is nearly unit elastic.     

The Korean Economy in Transition: In Search for a New Model

Abstract

Prior to the 1997 financial crisis, the Korean economy had based its growth policies on East Asia's economic catch-up model which was based mainly on the Japanese development experience. However, the events that lead to the 1997 crisis and the changes instituted in the Korean economy after the crisis have put to question whether the traditional East Asian growth model will continue to be viable. This paper examines two alternative models of development, namely the “Anglo-Saxon” and the “Continental European” models, and evaluates their relevance for Korea's future development challenges. Despite many common features these models share, they are also quite distinctive with regard to their treatment of the labor market system and the role of government. By focusing on the model's capacity to expand employment and to provide sustainable growth as the most important criteria, it is suggested that Korea should follow the “Anglo-Saxon model”, at least in the short- to medium-term. In comparing Korea's economy with other advanced economies when they were at the similar stage of development, it is found that Korea's growth potential lags behind that of countries such as Japan, Germany, Finland, and Ireland. The efficiency of Korea's investment is found to be only slightly better than Japan while it is inferior to all other advanced economies. Despite these challenges, Korea is apparently moving toward the “Continental European model”, with the Korean government increasing its own size and plans for further expenditures on social security and welfare. However, in order to ensure sustainable development with significant job creation, this paper argues that Korea should switch its direction and adopt the “Anglo-Saxon model” as soon as possible.     

Unanticipated vs. Anticipated Tax Reforms in a Two-Sector Open Economy

We use a two-sector neoclassical open economy model with traded and non-traded goods to investigate the effects of unanticipated and anticipated tax reforms. First, an unanticipated tax reform produces an expansion of GDP, labor, and investment, while an anticipated tax reform has opposite effects before the implementation of the labor tax cut. Quantitatively, if the traded sector is more capital intensive, GDP increases by 1.6 percentage points or declines by 2.7 percentage points after three years, depending on whether the tax cut is unanticipated or anticipated. Second, we find that GDP change masks a wide dispersion in sectoral output responses. As long as investment is both traded and non traded, a tax reform substantially raises the relative size of the non-traded sector after three years while traded output always drops. Third, a tax reform improves welfare in all scenarios, more so if the markup is endogenous, but less so if the shock is anticipated. Importantly, we find that welfare gains in a two-sector economy with capital accumulation and perfect access to external borrowing are between 39 % and 89 % higher than those in an economy without physical capital.     

What＇s So Special about China＇s Producer Services？ An Input-output Analysis

In the present study, five stylized facts about China ＂s producer services are established through international, intersectoral and intertemporal comparisons based on input --output tables. First, the overall service input ratio is the lowest in all the sample economies. Second, most producer services are supplied by the traditional labor-intensive sectors. Third, manufacturing is the biggest user of producer services, and service industry is the second, while the opposite is true for most of the other sample economies. Fourth, unlike other economies, China ＂s ＂R＆D＂ is characterized more by consumer services than producer services. Fifth, China has fairly lower service input ratios in almost all the industries. The backward and forward linkages coefficients are both smaller for ＂real estate activities＂ and ＂finance and insurance. ＂＂ Policy reform should focus not only on specific producer services but also on reducing obstacles that are inhibiting the balanced development of diverse producer services that will help China to optimize its economic structure.     

Effects of China's Structural Change on the Exports of East Asian Economies

The Chinese economy is slowing down and is in the midst of a structural transformation from export‐led and investment‐led growth to domestic demand‐led and consumption‐led growth. While there are widespread concerns among China's trading partners about the effect of the slowdown in China's growth on their exports, China's structural changes are also likely to have a significant impact: for example, China will import fewer machines and more cosmetics. The central objective of the present paper is to empirically examine the effect of China's structural transformation on the exports of East Asian economies, which have close trade linkages with China. We find that economies that have failed to increase the share of consumption goods in their exports to China have suffered larger declines in their quantities of exports to China. In addition, economies that have suffered losses in their shares of China's parts and components imports have faced reductions in their shares in China's total imports.     

Impact of Foreign Bank Presence on Foreign Direct Investment in China

We analyze the impact of foreign bank presence on foreign direct investment (FDI) in China. The connection between the two could be particularly relevant for an emerging economy like China because the supply of financial services provided by banks may act as a constraining factor. Foreign bank presence may then enable and foster FDI and not simply result from it. Our estimates demonstrate that FDI across regions in China is increasing in the existing network of regional branches of foreign banks, which itself is driven (and, therefore, instrumented) by the timing of the regional phasing out of the local limits for foreign banks on local currency business. The effect of foreign bank presence on FDI is particularly strong for some specific sectors (farming, manufacturing, construction, transportation, wholesale/retail trade and real estate) if those sectors are strongly represented in the source economies.     

Openness and growth in East Asia after the Asian crisis

Openness with respect to trade in goods, services and foreign direct investment has a positive marginal effect on growth. The fast-growing East Asian economies were early openers, and this contributed to their fast growth. However, East Asian countries are not relatively open today. This factor, together with the convergence effect of fast growth in the past, imply that their economies will slow down. Their growth prospects are further reduced by growing geographic discrimination against their goods and services in world markets, and the slow down of the Japanese economy.
