Who Gains from the Demographic Dividend? Forecasting Income by Age

Changes in the population age structure are known to influence the total income per person, but little is known about whether the changes are equally shared across the population or are concentrated on particular age groups and/or birth cohorts. The answer to this question has potentially important implications for income inequality, human capital investment, and fertility decision-making. We propose a new model of intergenerational transfers which distinguishes between the effects of changes in population structure and the effects of changes in family age structure. Using age-specific data from annual income and expenditure surveys of Taiwan between 1978 and 1998, we show that changes in age structure have had a very favorable effect on Taiwan's income growth. The gains are not equally shared by all age groups, however. Children and young adults have benefited the most, while the elderly have benefited the least. The population and family age structures have independent effects on per capita income; the effect of the population age structure is most important. Generational differences in per capita income are closely related to intergenerational differences in earnings, suggesting only a weak form of altruism. Finally, we predict that, on average, population aging will adversely influence the per capita income growth in Taiwan in the coming decades.     

Growth vs. level effect of population change on economic development: An inspection into human-capital-related mechanisms

This paper studies the different mechanisms and the dynamics through which demography is channeled to the economy. We analyze the role of demographic changes in the economic development process by studying the transitional and the long-run impact of both the rate of population growth and the initial population size on the levels of per capita human capital and income. We do that in an enlarged Lucas–Uzawa model with intergenerational altruism. In contrast to the existing theoretical literature, the long-run level effects of demographic changes, i.e. their impact on the levels of the variables along the balanced growth path, are deeply characterized in addition to the more standard long-run growth effects. We prove that the level effect of the population rate of growth is non-negative (positive in the empirically most relevant case) for the average level of human capital, but a priori ambiguous for the level of per capita income due to the interaction of three transmission mechanisms of demographic shocks, a standard one (dilution) and two non-standard (altruism and human capital accumulation). Overall, the sign of the level effects of population growth depends on preference and technology parameters, but numerically we show that the joint negative effect of dilution and altruism is always stronger than the induced positive human capital effect. The growth effect of population growth depends basically on the attitude to intergenerational altruism and intertemporal substitution. Moreover, we also prove that the long-run level effects of population size on per capita human capital and income may be negative, nil, or positive, depending on the relationship between preferences and technology, while its growth effect is zero. Finally, we show that the model is able to replicate complicated time relationships between economic and demographic changes. In particular, it entails a negative effect of population growth on per capita income, which dominates in the initial periods, and a positive effect which restores a positive correlation between population growth and economic performance in the long term.     

The Revenue Adequacy of Site Value Taxation in a Ricardian System of Economic Growth

A bstract . The federal administration has sought to reduce the growth of federal expenditures by shifting some government costs to state and local governments. An increased expenditure burden for the latter governments would require increased tax rates for existing types of taxes that have adverse impacts on economic incentives. Land taxes are considered as a source of revenue because of their efficiency aspects. Unfortunately this idea is all too often dismissed because of alleged revenue inadequacy. Thus an analysis is called for of the revenue adequacy of site value taxation in a Ricardian model of economic growth. The model allows analysis of revenue adequacy over time in an economic growth context that is suited for the long range tax-expenditure planning horizon with which local governments are faced. When revenue needs are primarily dependent upon the population size, and the fisc is initially operating at a deficit, for a land tax to permit attainment of balance, per capita rents must be increasing over time. Also when the economy's public service demand is primarily dependent upon income, deficits will not occur if rental share exceeds the share of income devoted to public output. Not all income goes to fiscal output, so rent eventually exceeds expenditures.     

IMPACT OF RELATIVE POPULATION CHANGE ON REGIONAL INCOME CONVERGENCE: EVIDENCE FROM TURKEY

The aim of this paper is to show the impact of relative population change on regional income convergence. Using the panel data of 64 Turkish provinces from 1987 to 2000, the results from modified convergence analyses show that both income and per capita income between provinces in Turkey indicate converging patterns. The convergence rates for the provincial per capita income, however, turned out to be about 30 percent larger than that of income. In order to examine this difference, the impact of relative population change on the growth process is incorporated using a decomposition analysis. The findings suggest that 17 percent of the 100 percentage point growth of per capita income resulted from the change in population share in favour of the provinces with high per capita incomes. The existence and pace of regional income convergence, therefore, may well be related to the degree of relative population change.     

Demographic transition and economic growth in China,India and Pakistan

The authors of this paper adopt a Solow–Swan model extended to include demographic variables to analyze the overall effect of demographic transition on economic growth. The results, based on data from seventy countries over the period 1961–2003, reveal that GDP per capita growth is positively related to the growth differential between the working-age population and the total population, and negatively related to child and old-age dependency ratios. Based on these results, they find that population dynamics explain 46 percent of economic growth in per capita GDP in China over the period 1961–2003, 39 percent in India, and 25 percent in Pakistan. Furthermore, population dynamics are expected to have a positive effect on economic growth in India and Pakistan over the period 2005–2050, and a negative effect in China.

The Nexus of Population,Energy, Innovation,and Complexity

For the past 200 years, humans have benefited from the abundant, inexpensive, and easily obtained energy of fossil fuels. Energy surpluses such as this are unusual in human history. In systems with little surplus energy, population growth is low and complexity emerges slowly due to the energetic costs it carries. On the rare occasions when energy is readily available, societies respond by growing rapidly. They must become more complex in response to the social, economic, and resource challenges of dense population. More complex societies are more expensive, requiring greater energy per capita. The process of increasing complexity necessitates greater energy production, creating a positive feedback cycle. Past societies have collapsed under such pressures. Population and complexity grew rapidly when the Industrial Revolution replaced economies based on annual solar radiation with economies fueled by fossil energy. The Green Revolution of the 20^th century is credited with preventing mass starvation, but it has made food production and sustaining population ever‐more dependent on high‐energy (low‐entropy) inputs. Some believe innovation will overcome the limitations of resources and permit unchecked growth. However, increases in complexity, innovation, and fossil energy are all subject to diminishing returns, and cannot continue to support population at current levels.     

The problem of population and growth: a review of the literature from Malthus to contemporary models of endogenous population and endogenous growth.

This review traces the evolution of literature on population and economic growth through the main paradigms suggested to explain the observed covariation of per capita income and population levels (or their rates of growth) over time and space, and determine which public policies will improve the human condition. As the main paradigms evolved, key variables were progressively treated as endogenous (instead of exogenous) to the growth process. After the introduction, section 2 looks at the "classical model" of Malthusian population theory and its refinements. Section 3 identifies empirical data that bears on the secular and cross-sectional association between levels of rates of growth of population and per capita income. The inconsistency of these data with the classical model helps explain declining interest in this model over time and increased interest in a more systematic type of population and growth theory. The beginning of this new interest is traced in section 4 with a look at the "neo-classical growth model" and the reformulated theory of population, which was based on Becker's work on fertility behavior. The first line of inquiry branching from these theoretical works (section 5) treats population as an endogenous variable in static and dynamic settings. The second line of inquiry (section 6) analyzes population and growth within a unified model of growth and development. In section 7, recent studies of key policy issues (population control policies, mandatory social security schemes) are surveyed. The concluding section notes that contemporary research must face the challenge of providing additional insights into longevity as an aspect of economic growth and development and of developing a model of endogenous population and economic growth based on heterogeneous agents.     

Highway Usage, Needs and Pollution as a Function of City Size and Population Density

Abstract . Using the data for 1990 urbanized areas from the 1972 Highway Needs Study, the effects of city size and population density on per capita vehicle use, miles of road, highway needs and “optimal”highway investment needs were investigated. The regressions showed that the miles of road per capita decrease with city population and population density. The vehicle miles of travel were found to increase with the land area of a city and its population. Although travel, and hence pollution increases in total as a city becomes more spread out, the suburban sprawl lowers the concentration of automotive pollutants in the atmosphere. Highway needs per capita decrease with population density, but increase with city size. Similar results are obtained when an approximation to optimal investment is used as the dependent variable.     

Consumers' surplus and the demand for cigarettes

This paper examines the demand for cigarettes in South Africa over a 20-year period from 1970 to 1989. Consumption per capita was found to be significantly determined by price and disposable income per capita; but not by advertising. Price and income elasticities and consumers' surplus were computed from the demand model. The question was raised as to whether or not consumers' surplus should be regarded as having been inferred from a health-hazard-discounted demand schedule. The answer depends on the degree to which smoking decisions are taken with full information or, conversely, are influenced by habit. Given the latter assumption, the consumers' surplus measured for cigarette consumption is nevertheless substantially higher than the estimated health costs of smoking as computed by the Medical Research Council.     

Wants and past knowledge: Growth cycles with emerging industries

This paper develops a theory of endogenous growth cycles focusing on the interaction between consumers' desire to satisfy an indefinite range of wants and firms' incentive to utilize knowledge from past production experiences. We show that firms endogenously form a number of distinguishable industries as accumulated knowledge induces them to agglomerate in the technology space. Knowledge accumulation in existing industries reduces production costs, but, as the diminishing returns from learning sets in, some firms start to adopt previously unexplored technologies so that their new goods fit consumers' unsatisfied wants and attract large demand. Thus, sporadic emergence of new industries generates growth cycles, where both the timing and the new technology to be adopted are endogenously determined. New industries based on new technology reduce the rate of per capita GDP growth in the initial phase, but nonetheless are indispensable for sustained economic growth in the long run.     

On the simultaneity problem in the aid and growth debate

This paper shows that foreign aid has a significant positive average effect on real per capita gross domestic product (GDP) growth if, and only if, the quantitatively large negative reverse causal effect of per capita GDP growth on foreign aid is adjusted for in the growth regression. Instrumental variables estimates show that a 1 percentage point increase in GDP per capita growth decreased foreign aid by over 4%. Adjusting for this quantitatively large, negative reverse causal effect of economic growth on foreign aid shows that a 1% increase in foreign aid increased real per capita GDP growth by around 0.1 percentage points.

Testing neoclassical convergence in regional incomes and earnings

The time-series properties of per capita income and per capita earnings in the regions of the United States are tested for consistency with the neoclassical growth model's prediction of convergence. We find evidence for per capita income convergence for U.S. regions during the 1929–1990 period after allowing for a trend break in 1946. These findings support the neoclassical model's prediction of convergence. The evidence for per capita earnings convergence is, however, less conclusive. Shocks to per capita earnings are found to be more persistent than shocks to per capita income. This implies that the regional distribution of transfer payments tends to smooth the effects of deviation on relative regional per capita earnings and reinforce trends in per capita income convergence.     

我国大都市区集聚与扩散的空间计量分析——基于空间面板数据

随着"疏散化"趋势的到来,我国大都市地区所呈现的集聚与扩散趋势逐渐明显。以我国128个大都市区为例,对其经济发展在空间上的集散特征进行空间自相关分析。全局莫兰指数表明,2000年至2017年我国大都市区经济发展整体上呈现显著的集聚特征,但是集聚程度呈现下降的趋势。从东中西和东北地区角度看,东部地区和东北地区均具有显著的扩散趋势,但是原因不同;中部大都市区的集聚程度具有下降的趋势;而西部大都市区具有显著集聚上升的趋势。空间计量分析结果表明,城市化率、人口规模和城镇居民人均可支配收入水平均对大都市区的经济增长率具有显著的空间正向关系,且居民人均收入水平对城市经济增长率的影响程度最大,大都市区之间经济发展的空间溢出效应较为显著,经济发展水平较高的大都市区辐射带动作用较强。最后,从顺应大都市区发展趋势、因地制宜制定城市发展规划以及合理分布人口规模和提高居民收入水平三个角度提出对策建议。

What has caused China’s economic growth?

Economic growth is driven by numerous factors. However, traditional economic theory focuses on certain key reasons, while ignoring the impact of other factors. Since 1978, China has achieved unprecedented economic growth, but also faces low per capita GDP. To clarify the driving forces behind this situation, we used per capita GDP to represent China’s economic growth and performed total factor analysis based on 13 variables in 7 socioeconomic dimensions using panel data from 30 Chinese provinces over the 40 years since China opened to the west in 1978. We found similar determinants in different regressions. Internal trade, privatization and investment were the primary factors driving Chinese economic development. Surprisingly, we found that the contribution of foreign trade to economic growth (per capita GDP) was weak. Education had a much smaller contribution than science and technology. Using per capita income as the dependent variable to provide a robustness test, we found that China’s income distribution has not paralleled its economic development and the distribution of the benefits of GDP growth to citizens must be improved. China’s experience demonstrates that promoting economic growth requires coordinated development of many factors, and that different policy preferences should be adopted to meet different economic development conditions.
