避免“中等收入陷阱”的国际比较

从国际经验看,人均GDP超过4000美元阶段,如果不及时转型,继续延用过去的经济发展战略,容易积累矛盾,陷入"中等收入陷阱"。拉美一些国家在长达30年里没有走出"中等收入陷阱",原因也在于此。当前,中国人均GDP已经超过4000美元,正处在向高收入国家迈进的阶段。通过国际比较,探索避免"中等收入陷阱"的一般规律,有助于中国加快转变经济发展方式,实现公平与可持续的发展。     

Is there a poverty trap for developing countries? Polarization: Reality or myth

A general view that as between countries ‘the rich are getting richer while the poor are getting poorer’ supported in the development literature by explanations relating to cumulative causation, economies of scale etc., and statistically based on the relation between GNP per capita in 1978 and its growth rates during 1960–1978, is shown to contain considerable elements of ‘myth’ or statistical ‘delusion’. The ‘naïve’ polarization hypothesis based on income levels at the end of the period over which growth rates are measured is left with a much weakened empirical basis when the proper substitution of levels of income at the beginning of the period is made. This is particularly so for low- and middle-income countries taken separately, while for the 18 industrialized countries a strong tendency towards convergence in per capita incomes emerges. Finally, for the growth in manufacturing value added during 1960–1977 a significant tendency towards convergence was observed in the case of a group of 24 least developed countries.     

Financial integration in East Asia: Evidence from panel unit root and panel cointegration tests

The aim of this paper is to investigate the degree of financial integration for selected East Asian countries from 1988 to 2006 using the recently developed panel unit root and panel cointegration techniques. Investment and savings rates are found to be nonstationary and not to be cointegrated in panels. We estimate modified Feldstein–Horioka equations and our results reveal a high degree of financial integration. When we homogenize our data, results show that high-income countries have stronger financial integration than middle-income countries. Finally, we proceed to stability tests in order to test if there is a crisis effect and we find that financial integration is stronger in the post-crisis period.     

中国经济如何跨越中高等收入陷阱

我国2010年人均GDP已经突破3945美元,根据世界银行对世界各经济体的最新分类标准,我国已经步入中高等收入国家行列,但与此同时我国的收入差距不断拉大。如何将收入差距控制在合理范围内,成功地跨越中高等收入陷阱是当前的紧要问题。本文通过对我国人均GDP及其基尼系数的协整检验发现,我国经济增长与收入分配之间存在一种稳定的长期均衡关系。只有合理的处理我国的收入分配差距问题才能达到经济的持续发展,从而跨越高中等收入陷阱。     

Economic Growth and Income Inequality: Evidence from Dynamic Panel Investigation

This paper empirically investigates the effect of income inequality on economic growth using extended panel data covering a broad range of developing and developed countries. We use system generalized method of moments (GMM) techniques in a dynamic panel analysis, which alleviates the possible positive bias in difference GMM due to the persistence of lagged dependent variables as instruments. We find strong evidence of a negative effect on growth from income inequality, which contradicts the findings of Forbes [2000, September. A reassessment of the relationship between inequality and growth, American Economic Review, 90(4), pp. 869–887] and Li and Zou [1998, October. Income inequality is not harmful for growth: Theory and evidence, Review of Development Economics, 2(3), pp. 318–34]. Further analyses using combined Gini coefficients show that the difference can be overall attributed to the problem of omitted control variables and the differences in how the variations in inequality across countries are reflected. We also find that the negative effects of inequality on economic growth can be of great significance when using a sample of less developed countries or more recent inequality data set.     

On the Impact of Foreign Aid in Education on Growth: How Relevant Is the Heterogeneity of Aid Flows and the Heterogeneity of Aid Recipients?

This paper examines whether foreign aid in education has a significant effect on growth. We take into consideration the heterogeneous nature of aid as well as the heterogeneity of aid recipients—we disaggregate the aid data into primary, secondary, and higher education, and run separate regressions for low income and middle income countries. We find that the effect of aid varies by income as well as by the type of aid. Thus our results underscore the importance of the heterogeneity of aid flows as well as the heterogeneity of recipient countries when analyzing the effect of aid on growth. JEL no.

Panama's exports and its sovereign debt

Conclusion Panama has a foreign debt that represents 81.2 percent of GNP. In absolute terms, this is not large by the standards established by countries such as Mexico. For countries like Panama, which are not in the severely indebted middle-income countries, there is a tendency to overlook them with debt assistance programs. In 1989, the Brady Initiative recognized the need to help SIMICs and the Paris Club also stepped in with rescheduling agreements primarily for SIMICs with high official debt. In the 1980s, Panama rescheduled $594 million in debt.That does not reduce the debt; rather, it gives the country more time to pay it off. Exports (or income) growth, if used exclusively to repay the debt, could accomplish that goal in 39 years. But the relationship between existing interest rates and export growth cannot be expected to endure for so long. In fact, it might be impossible for Panama to ever pay off its debt, particularly when its long-term and short-term sum exceed its GNP. If the ratio of debt-to-exports is indeed constant, then Panama will be able to outgrow the debt as long as export growth is greater than the cost of servicing the debt.     

The impact of gender differences on determinants of job satisfaction among Chinese off–farm migrants in Jiangsu

This study examines the effect of own income versus reference group income and the subjective factors considered important in a job for a sample of off–farm migrants in China. We find that own income has a positive effect on job satisfaction while the effect of reference group income is gender specific. We find evidence that males experience a tunnelling effect (higher income co-workers increase their job satisfaction) while females experience a jealousy effect (higher income co-workers lower their job satisfaction). We explain this result in terms of men reacting more positively in competitive environments and that, in China, males have better prospects for promotion. We find that compared with employees in western countries, off–farm migrants in China place much more emphasis on income and less importance on collegiality and job stability.     

Can countries rely on foreign saving for investment and economic development?

Contrary to widespread presumption, a surprisingly large number of countries have been able to finance a significant fraction of their investment for extended periods using foreign finance. While many of these episodes are in countries where official finance is important, we also identify episodes where a substantial fraction of domestic investment is financed by private capital inflows. Although there is evidence of a positive growth effect of such inflows in the short run, that positive impact dissipates after 5 years and turns negative over longer horizons. Many such episodes end abruptly, with compression of the current account and sharp slowdowns in investment and growth. Summing over the inflow (current account deficit) episode and its aftermath, we find that growth is slower than when countries rely on domestic savings. The implication is that financing growth and investment out of foreign savings, while not impossible, is risky and too often counterproductive.     

Carbon emissions and income inequality

We find that the distribution of income matters to aggregatecarbon dioxide emissions and hence global warming. Higher inequality,both between and within countries is associated with lower carbonemissions at given average incomes. We also confirm that economicgrowth generally comes with higher emissions. Thus our resultssuggest that trade-offs exist between climate control (on theone hand) and both social equity and economic growth (on theother). However, economic growth improves the trade off withequity, and lower inequality improves the trade off with growth.By combining growth with equity, more pro-poor growth processesyield better longer-term trajectories of carbon emissions.     

The Role of Property Rights in the Relationship between Capital Flows and Economic Growth in SSA: Do Natural Resources Endowment and Country Income Level Matter?

This paper studies the role played by the quality of property rights in the linkages of international capital flows into sub‐Saharan African (SSA) economies. Using panel data of 36 SSA countries over the period 1996–2015 and the ARDL procedure with the Pooled Mean Group regression method appropriate for non‐stationary panel data estimation, we account for the joint effects of property rights quality and openness to foreign capital flows on economic growth. We uncover the existence of a property rights quality threshold beyond which property rights either amplifies the spillovers effects or attenuates the negative effect of capital flows on economic growth. For instance, it takes a level of property rights of at least 60 to have a positive long‐term impact of capital flows on economic growth in natural resource‐poor African countries. The quality of property rights matters more to obtain spillover effects of capital flows on growth in natural resource‐poor countries than in their peer natural resource‐rich countries. Finally, with regard to the countries' income levels, capital flows have significant long‐term spillovers effects on economic growth in advanced African economies than in their low‐income peers.     

Inward and outward foreign direct investment and poverty: East Asia vs. Latin America

Using panel data of 12 middle-income countries in East Asia as well as Latin America, this paper examines how openness in general and outward FDI in particular affects poverty. While economic growth and trade openness are found to be associated with lower poverty, both outward and inward FDI adversely affect the mean income of the poorest quintile of the population. The results hold in both regions, though the Latin American countries seem to be in a somewhat less favorable situation.     

Inflation and economic growth: A dynamic panel threshold analysis for Asian economies

This paper investigates the existence of a threshold level for inflation and how any such level affects the growth of Asian economies. We use a dynamic panel threshold growth regression, which allows for fixed effects and endogeneity. We observe a nonlinear relationship between inflation and economic growth for 32 Asian countries over the period 1980–2009. We detect an inflation threshold of approximately 5.43%, at a 1% level of significance. We find that inflation hurts growth when it exceeds 5.43% but has no effect below this level. Different estimation methods determine that the effect of inflation on growth is robust. Our findings may be useful to central banks as a guide for inflation targeting.     

Revisiting Growth‐Poverty Relationship: A Medium‐Term Causality Approach

This article examines the potential medium‐term causal relationship between changes in Gross Domestic Product (GDP) per capita and poverty in developing countries during the 1970s–1990s. For this purpose, we use panel data model evaluation techniques to test the out‐of‐sample forecasting performance of competing models. We conclude that the evidence supports the hypothesis that increases in GDP per capita cause unidirectional poverty reduction, measured by the $1/day poverty rate, in the period 1970s–1980s. The results are similar when analysing low‐ and middle‐income countries and mid‐high‐ and very high‐inequality countries separately. However, in the period 1980s–1990s, it is only statistically significant for low‐income countries.     

Job satisfaction and relative income in economic transition: Status or signal?: The case of urban China

We use two datasets for urban China to examine whether an increase in reference group income lowers or increases job satisfaction. The former is consistent with a status effect — an increase in the income of others lowers my satisfaction because I feel jealous. The latter is consistent with a signal effect — an increase in the income of others might make me jealous, but it also provides an information signal about my future prospects. When we use a single item indicator of job satisfaction we find no support for a status or signal effect; however, when we use a psychometrically valid instrument to measure job satisfaction, we find some support for the existence of a status effect. We consider the components of job satisfaction through which the status effect operates. We find that the status effect operates through satisfaction with co-workers, operating procedures, pay and supervision.     

Telecommunications Investment in Africa: Implications of US Reform of the International Settlement Rate System*

Abstract: This paper investigates the possible effects of the US reform of the international settlement rate system on telecommunications investment in Africa. We estimate a telecommunications investment equation using a panel data of 51 African countries during the 1991–2003 period and find that settlement payments have significantly positive effects on telecommunications investment in African countries. A 10 percent increase in settlement payment, on average, increases the telecommunications investment expenditure to GDP ratio by 3.4 percent over a three‐year period. Using previously calculated revenue loss from the US reform, our estimates suggest that African countries stand to lose between 4.4 to 11 percentage points of their telecommunications investment in the medium run and with it, possible decreases in income growth rate. However, we argue that African countries can counter the effects of this revenue loss by increasing the efficiency of telecommunications investment through appropriate market restructuring, including the promotion of competition and privatization.     

Financial development and top income shares in OECD countries

We examine the causal impact of financial development (FD) on top income shares for a panel of 14 OECD countries—five Anglo‐Saxon countries, eight continental European countries, and Japan—over a 110‐year period. In our main General Method of Moments estimates, we find that a 1‐percentage‐point change in FD increases the top 1% income share by 0.2%. In distribution terms, a 1‐SD incr=ease in FD increases the top 1% income share by around 0.4 of an SD. The effects are robust to various measures of top income shares and FD and alternative estimation techniques, including nonparametric estimation. FD is typically viewed in positive terms in that it makes it easier to access credit and facilitates economic growth. Our results are important because they contribute to understanding of the potential negative effects of FD.     

Is there conspicuous consumption in Japan?

This paper examines price dependent preferences in Japan. We do find some evidence of aggregate price and income dependent preference variation, but much less than in other industrialized countries. The homogeneity tests support the hypothesis of the existence of Veblen effects across some commodity groups.     

Income inequality and ethnic cleavages in Malaysia: Evidence from distributional national accounts (1984–2014)

In this paper, by combining information obtained from national accounts, household surveys, and fiscal data, we document the evolution of income inequality in Malaysia, not only at the national level (for the period of 1984–2014) but also by ethnic group (for the period of 2002–2014). To our knowledge this is the first attempt to produce inequality measurements of Malaysia, which are fully consistent with the national accounts. Our research shows that despite Malaysia’s exceptional economic growth rate, its growth has been inclusive. For the period of 2002–2014, the real income growth for the bottom 50 % is the highest (5.2 %), followed by the middle 40 % (4.1 %), the top 10 % (2.7 %) and then the top 1 % (1.6 %). However, while average growth rates are positive across all ethnic groups (Bumiputera 4.9 %, Indians 4.8 %, and Chinese 2.7 %), the highest growth of real income per adult accrued to the Bumiputera in the top 1 % (at 8.3 %), which sharply contrasts the much lower growth rate of the Indians (at 3.4 %) and negative income growth rates of the Chinese (at −0.6 %). Despite the negative growth rate, the Chinese still account for the lion’s share in the top 1 %. In 2014, 60 % of the adults in the top 1 % income group are Chinese, while 33 % Bumiputera, and 6 % Indians. We conclude that in this period, Malaysia’s growth features an inclusive redistribution between income classes, but with a twist between racial groups.     

The rise and fall of worldwide income inequality, 1820–2035

The development process and the demographic changes that are a central element of it explain both the nearly two centuries of increasing income inequality prior to 2000 and the reversal of this trend that followed. There are at least four phases of the development process: (1) Malthusian pre-development, (2) initial growth, (3) improved productivity, and (4) receding growth. Prior to the industrial revolution, the entire world was in the Malthusian Phase 1. During 1820–1950, about 20 countries, mostly in Western Europe, North America, and Oceania, moved out of Phase 1 and began to grow more rapidly. But, per capita income levels in the rest of the world continued to stagnate and worldwide income inequality widened continuously for at least 150 years following the Industrial Revolution. Around 1960, developing countries began to escape the Malthusian trap and move into Phase 2 of development. By the latter part of the 20th century, many developing countries were achieving growth rates equal to or greater than the high-income countries, slowing the rise in inequality. By 2000–2015 most developing countries were in either Phases 2 or 3 of development, while most of the high-income countries were moving into Phase 4, leading to a sharp reduction in worldwide income inequality. The recent reductions in worldwide income inequality are likely to continue in the near term because of the continuation of the more favorable demographic changes in developing compared to high-income countries.
