Inequality and income: The mediating effects of social spending and risk

This paper estimates models of social spending, income risk, and per capita income levels using data from a post-war panel of OECD (Organisation for Economic Cooperation and Development) countries. The objective is to test two theories about the pathway from inequality to per capita income. According to one theory, inequality reduces incomes because it induces social spending, which acts as a drag on the economy. The results here suggest, however, that inequality does not seem to induce social spending, and social spending does not seem to lower per capita incomes. According to a second theory, inequality causes upheaval which adds to the volatility of per capita income, which may reduce the level of per capita income. The results suggest, however, that volatility, measured here as the standard deviation of per capita income, has little measurable impact on either per capita income or social spending. The mainsprings of per capita income are more likely to be the traditional factors: the work force, human capital, and physical capital.

Social capital, innovation and growth: Evidence from Europe

This paper investigates the interplay between social capital, innovation and per capita income growth in the European Union. We model and identify innovation as an important mechanism that transforms social capital into higher income levels. In an empirical investigation of 102 European regions in the period 1990-2002, we show that higher innovation performance is conducive to per capita income growth and that social capital affects this growth indirectly by fostering innovation. Our estimates suggest that there is no direct role for social capital to foster per capita income growth in our sample of European Union countries.     

低碳约束对产业集聚的门槛效应分析

产业集聚作为重要的产业组织形式,其影响因素一直是理论界研究的重点,但鲜有学者直接研究低碳约束对产业集聚的影响。基于2000-2012年中国内地30个省（市、自治区）的数据,利用门槛回归方法,从人均收入和人力资本两个角度,检验了低碳约束对产业集聚的门槛效应。收入门槛的检验结果表明,在中、低收入阶段,低碳约束抑制产业集聚,而在高收入阶段,低碳约束则显著促进地区产业集聚;人力资本门槛的检验结果表明,在高人力资本阶段,低碳约束能够显著带动地区产业集聚,在中低人力资本阶段则相反。     

Industrial development in Malaysia and Singapore: Empirical analysis with multiple‐cone Heckscher–Ohlin Model

This paper employs the multiple‐cone Heckscher–Ohlin model to analyze industrial development in Malaysia and Singapore. In particular, we focus on industrial upgrading along with capital accumulation as a key determinant for the cross‐country difference in production technology and income. By pooling two countries’ data on factor endowment and sectoral output in manufacturing from 1990 to 2008, we estimate the common industrial development paths of the two‐cone Heckscher–Ohlin model, the Rybczynski linear relationship between capital–labor ratio and sectoral output per capita. Our results demonstrate that, after controlling for quality of workers (by educational attainment), the two countries resided in different cones during our sample period, implying that Singapore succeeded in accumulating capital steadily with the support of foreign investment and upgrading its industry mix to make it more capital‐intensive. The separation of cones is also consistent with the observed gap in gross domestic product per capita between the two countries. Furthermore, we implement a factor‐augmenting productivity test to see the gaps in efficiency of capital and human‐capital‐augmented labor and confirm no significant difference between the two countries.     

贸易开放、人力资本与 中国区域收入空间效应* ——基于地级及以上行政区域经验数据分析

本文基于中国326个地级及以上行政区域2010-2012年的数据,利用空间杜宾增长模型（SDM）来测算贸易开放对中国区域人均收入的影响。本文测算了各个区域贸易开放和人力资本对人均收入水平的直接、间接和总影响。结果表明：一个区域的贸易开放程度越高越能促进当地经济的发展,对相邻区域的人均收入也会产生正的影响。同时笔者也发现,人力资本对中国各个区域的经济增长会产生正的直接和间接影响。     

Growth, Attitudes towards Women, and Women's Welfare

The authors find that attitudes towards women are more progressive as per capita income rises and that the quality and quantity of women's human capital increases with per capita income. Prior to presenting these empirical results, the authors first demonstrate the importance of these relationships with a simple model that shows how a feedback loop between attitudes towards women, investment in women's human capital, and income affects the dynamic path of the economy. Depending on the nature of the relationship between per capita income and attitudes towards women, they identify the possibility of a gender-equity poverty trap. Finally, they extend the model to show the dynamic interplay between attitudes towards women, income, and fertility.     

Is India Shining?

The popular perception about economic reforms having benefitted only the richer districts of India between 1999/2000 and 2004/2005 is investigated. Using the spatial dynamics of district‐level per‐capita income it was found that income distribution did not change between the years examined. It is argued that this is because of per‐capita income across districts being spatially positively correlated. Physical infrastructure, human capital, and factories are identified as factors responsible for increase in income for both the rich as well as the poor districts. Infrastructure, physical or social, is a key component of growth in India. A policy impact analysis shows development of better drainage and potable water systems has a large impact on income. For the year 2001/02, it was found that for every 1% increase in closed drainage system and potable water, district‐level median income increases by 1.39% and 0.21%, respectively.     

International Trade and Growth Miracles: the Implications of Nonhomothetic Preferences

If the rate of saving increases with income then a low per capita level of the capital stock may be self‐sustaining. In these circumstances international trade may allow an economy to quickly increase its per capita capital stock in a self‐reinforcing “growth miracle” process. A labor‐abundant economy trading with a capital‐abundant economy will see its wage rate rise relative to autarky. This rise in the wage rate also increases the savings rate and so raises the following period’s per capita capital stock. In this way a low‐income economy may exhibit large and permanent increases in its level of GDP per capita after opening its markets to international trade.     

ECONOMIC FREEDOM AND INCOME LEVELS ACROSS U.S. STATES: A SPATIAL PANEL DATA ANALYSIS

There is a large literature estimating the effect of economic freedom on economic growth or income levels. Most studies examine the relationship between economic freedom and growth or income levels for countries, while a few examine the relationship for U.S. states. Absent in the state‐level literature is consideration of the presence of spatial spillovers affecting the freedom‐income relationship. Neglecting to account for spatial autocorrelation can bias estimation results and therefore inferences drawn. We find evidence of a spatial pattern in real per‐capita gross state product (GSP) that affects nonspatial estimates of the freedom‐income relationship. Taking into account the direct and indirect effects of economic freedom on real per‐capita GSP, we find a 10% increase in economic freedom is associated with a 5% increase in real per‐capita GSP.

Regional convergence clubs in Europe: Identification and conditioning factors

The aim of this paper is to empirically identify convergence clubs in per capita incomes of European regions and to investigate whether initial conditions − as suggested by the club convergence hypothesis − are responsible for club formation. To tackle this issue, we propose a two-step procedure in which we first endogenously identify groups of regions that converge to the same steady state level, and in a second step we investigate the role of starting conditions and structural characteristics for a region's club membership. Our sample comprises 206 European NUTS2 regions between 1990 and 2002. The results strongly support the existence of convergence clubs, indicating that European regions form six separate groups converging to their own steady state paths. Moreover, estimates from an ordered logit model reveal that the level of initial conditions such as human capital and per capita income plays a crucial role in determining the formation of convergence clubs among European regions.     

Closing the Technology Gap?

This paper focuses on the dimensions shaping the dynamics of technology. We present a model where the knowledge stock of a country grows over time as a function of three main factors: innovation intensity, technological infrastructures, and human capital. The latter two variables determine the absorptive capacity of a country as well as its innovative ability. We then carry out an empirical analysis that investigates the dynamics of technology in a large sample of economies in the last two‐decade period, and studies its relationships with income per capita growth. The results indicate that the cross‐country distributions of technological infrastructures and human capital have experienced a process of convergence, whereas the innovative intensity is characterized by increasing polarization between rich and poor economies. Thus, while the conditions for catching up have generally improved, the increasing innovation gap represents a major factor behind the observed differences in income per capita.     

Income inequality,unemployment, and poverty in Nigeria: a vector autoregressive approach

The main features of poverty are low levels of consumption and income, a fact‐of‐life in most African countries. This paper analyzes the fundamental trends of per capita income, government capital expenditure, the human development index, and the rate of unemployment in the Nigeria. A vector autoregressive model finds that: A reduced unemployment rate improves human development and consequently reduces poverty. As growth in public capital expenditure rises, unemployment falls and the human development index improves. Therefore, infrastructure‐based policies, which initially reduce unemployment, will also improve the living conditions of Nigerians in the end.     

Misallocation of talent,teachers’ human capital,and development in Brazil

In this study, we investigate the allocation of talent in an economy where teachers play a critical role in developing the human capital of the workforce. To this end, we formulate a Roy model with externality in the occupational choice, as the quantity and quality of teachers are key determinants of workers’ human capital. Our analysis suggests that when individuals with greater abilities opt for teaching careers, the entire workforce benefits. However, frictions in the labor and educational goods markets may lead to a suboptimal allocation of talent and hinder economic growth and development. Our model is calibrated to the Brazilian economy, and our findings reveal a negative correlation between frictions in the teacher’s occupation and per capita output in the Brazilian states. Our results indicate that eliminating friction in the labor market could result in a 16.94% increase in Brazilian income.     

A Spatial Econometric Analysis of Cultural Dimensions,Technology Knowledge and Economic Growth

Using data from 65 countries over the period 1980–2003, this paper investigates the role that cultural dimensions play in the process of technological change, innovation and adoption and consequently on the steady state level of output per worker and its growth, using spatial econometrics techniques to account for spatial dependence between countries. Initial findings indicate that differences across cultural dimensions act as a leveling effect but not as long run growth determinants. In addition, when controlling for physical and human capital accumulation, culture plays a much smaller role in explaining differences in income per capita than initially thought, with little effect on output per worker growth along the transitional dynamics path. Spatial econometric considerations are relevant in explaining differences across rates of growth of per worker output, but not in terms of steady‐state levels of income.     

Global distribution and dynamics of economic freedom: Non-parametric approach

The paper exploits the distributional dynamics and structural changes in the endogenous distribution of economic freedom across countries over time by utilizing the Rosenblatt–Parzen Kernel density estimator compared to the original distribution based on the methodology proposed by the Heritage Foundation. We utilize the distribution of economic freedom as a tool to identify which policies enhanced the overall level of economic freedom. We develop the distribution of endogenous economic freedom by decomposing effects of economic freedom on the level of income per capita in IV–2SLS estimation framework for a panel of 134 countries to identify the effect of institutions of economic freedom on the level of per capita income. Structural estimates indicate that improvements in the monetary, fiscal, and labor freedom exert the strongest direct effect on the level of economic freedom and indirect effect on the level of real income per capita. Our study demonstrates considerable differences between the original and endogenous distributional dynamics of economic freedom over time. In exploiting the non-parametric setting of endogenous economic freedom, we identify a recent emergence of twin-peak distribution across countries where developing nations have improved the level of economic freedom considerably compared to the initial year.     

Human capital,age structure and growth fluctuations

This article assesses the empirical relationship between per capita income growth fluctuations and the age-structured human capital variations across four groups of geographically clustered developed and developing countries from spatial perspective. We estimate a spatial Vector Autoregressive (VAR) model of income dynamics where the distance between countries is defined on relational space based on their similarity in appropriation tendency of human capital in the production processes. These distances are computed using a newly developed human capital data set which fully characterizes the demographic structure of human capital, and thus underlines the joint relevance of demography and human capital in economic growth. Spatial effects on growth interdependence and complementarity are then explored with respect to the proposed distance metrics. Our results imply that significant cross-country growth interdependence based on human capital distances exists among defined country groups suggesting the need for a cooperative policy programme among them. We also find that the relationship between economic growth and human capital is highly nonlinear as a function of the proposed human capital distance.     

Foreign direct investment and China's regional income inequality

China's widening regional income inequality coupled with its pronounced regional disparity in foreign direct investment stock since 1990 has claimed the attention of many scholars. While some researchers confirm regional disparity in China's foreign direct investment, others attribute the widening regional income inequality to this regional disparity. This paper thus assesses the impacts of China's stock of foreign direct investment on its regional income inequality using simultaneous equation model and the Shapley value regression-based decomposition approach. Our results suggest that China's stock of foreign direct investment has accounted for merely 2% of its regional income inequality. Furthermore, the contribution ratio of per capita foreign direct investment stock to China's regional income inequality has relatively been on a steady decline since 2002. The decomposition results also reveal that provincial per capita physical assets account for over 50% of the nation's income inequality and 65% of the increases in income inequality since 1990. The other two important determinants of regional income inequality are province location and educational level. However, educational level is found to have a decreasing effect on regional income inequality.

Export Destination,Product Quality and Wages in a Middle‐Income Country. The Case of South Africa

A robust finding in the firm‐level literature is that exporting firms pay higher wages. Using South African data this paper investigates the relationship between export destination and wages at a worker level. South Africa, a middle‐income country, has two distinct main export markets—a regional market where per capita incomes are lower than at home, and an international market with higher per capita incomes. Our estimates show that workers in firms that export to the region earn less than those that produce for the domestic market. Those in firms that export outside the region earn more than either domestic producers or region‐only exporters. Much of this difference in wages can be explained by the premium the different types of exporters pay for skills. These results support previous studies which suggest that export destination is related to product quality which in turn is related to worker quality and therefore wages.     

Educational Attainment and Regional Economic Performance in Mexico

A growing number of studies confirm the importance of educational attainment and human capital investment as a means for improving per capita income performance. In developing countries, attention to this linkage has primarily been carried out using national data aggregates. For relatively large countries such as Mexico, it is helpful to conduct similar analyses that document regional market income patterns. This paper utilizes 2000 census data for all 31 states and the Federal District in Mexico City to quantify regional income performance. Similar to other studies conducted using regional data in higher income economies, results confirm strong links between education and incomes across Mexico.
