SOCIAL STATUS AND THE GROWTH EFFECT OF MONEY*

It has been shown that in a standard one‐sector AK model of endogenous growth with wealth induced preferences for social status, the economy's growth rates of real output and nominal money supply are positively related when the cash in advance constraint is applied solely to the household's consumption purchases. However, a positive output growth effect of money/inflation is not consistent with the existing empirical evidence. We show that when gross investment must be financed by real money balances as well, this result is overturned, i.e. higher inflation is detrimental to economic growth, because of a dominating portfolio substitution effect.     

Consumption externalities, production externalities, and efficient capital accumulation under time non-separable preferences

The effects of consumption and production externalities on economic performance under time non-separable preferences are examined both theoretically and numerically. We show that a consumption externality alone has long-run distortionary effects if and only if labor is supplied elastically. With fixed labor supply, it has only transitional distortionary effects. Production externalities always generate long-run distortions, irrespective of labor supply. The optimal tax structure to correct for the distortions is characterized. We compare the implications of this model with those obtained when the consumption externality is contemporaneous. While some of the long-run effects are robust, there are also important qualitative and quantitative differences, particularly along transitional paths.     

Geography,health, and the pace of demo-economic development

This paper investigates the impact of subsistence consumption and extrinsic and intrinsic causes of child mortality on fertility and child expenditure. It offers a theory for why mankind multiplies at higher rates at geographically unfavorable, tropical locations. Placed into a macroeconomic framework this behavior creates an indirect channel through which geography shapes economic performance. It is explained why it are countries of low absolute latitude where we observe exceedingly slow (if not stalled) economic development and demographic transition.     

Energy consumption,economic growth and environmental degradation in OECD countries

The interdependence among energy consumption, economic growth and environmental degradation has become an important public policy priority among OECD countries. Yet, the related literature provides conflicting results when describing the dynamic nature of such a relationship and the way it affects countries' development path. Using a sample of 35 OECD countries over the period 2000–2014, we find that economic growth and energy consumption patterns contribute to the enhancement of countries' environmental performance levels. In contrast to a large stream of empirical research, our findings highlight that countries' economic development path and their energy consumption patterns have started to align with their environmental policies. The results are robust since we utilize different aspects of countries' environmental degradation such as carbon dioxide emissions, ecological footprints and countries' environmental performance levels. Finally, the analysis of the dynamic interrelations among countries' energy consumption, economic growth and environmental degradation levels, reveals the necessity to promote sustainable development through a coexistence rather than through a trade-off mechanism.     

Variety of products,public capital,and endogenous growth

This paper develops an extension of the endogenous growth model with variety expansion presented in Romer [Romer, P.M., 1990. Endogenous technical change, Journal of Political Economy 98, part 2, S71–S102] by considering public capital accumulation. Characterizing the transitional dynamics, the growth rate of consumption traces (and available number of intermediate goods also might trace) an S-shaped converging path to the equilibrium growth rate, similar to a logistic growth curve, if the intensity of public capital is sufficiently high. We also show that public investment enhances economic growth because it stimulates demand for intermediate goods and raises the market interest rate.     

Modinomics: Design,Implementation, Outcomes,and Prospects

This paper presents an analysis of the key elements of Modinomics, defined as “everyone's participation, everyone's progress.” It investigates the reasons why Modinomics was necessary, the key elements of Modinomics, and how this policy was implemented. It argues that India's economic policy has had continuity since the economic reform package of 1991, so Modinomics has involved a high component of better implementation. Nevertheless, there have been some major policy changes as well. The paper discusses the deep structural reforms of demonetization and a Goods and Services Tax as well the new Insolvency and Bankruptcy Act. The paper examines the record of economic growth under Modi as well as new welfare and employment programs to make economic growth more inclusive. Finally, the paper examines the medium and long‐term growth prospects for India.     

A multi-factor efficiency perspective to the relationships among world GDP, energy consumption and carbon dioxide emissions

Most of the research articles on climate change study the relationships between economic growth, and, carbon dioxide (CO₂) emission or energy consumption separately for analyzing the impacts of economic growth and energy consumption on global carbon dioxide emissions. In this paper, the linkages among CO₂ emissions, Gross Domestic Product (GDP) growth and energy consumption are studied simultaneously using Data Envelopment Analysis (DEA). The time period considered for the study is 1980-2001. The results show that world in the year 1980 was the most efficient in achieving the highest economic growth, emitting least carbon dioxide for a given level of energy consumption for that year. The efficiency index reduced in the next 8 years, fluctuated with a declining trend for the next 7 years, and began to rise from 1996 till 2001. The model is further extended in this paper for technology forecasting to identify the links between energy consumption and carbon dioxide emissions for achieving projected levels of GDP under two different assumptions on efficiency index. It has been identified using the forecasting model that, when the carbon dioxide emissions are restricted to the levels emitted in the year 1990 and when the efficiency index for the year 2025 is assumed to be at the level registered for the year 1980 (highest value), the non-fossil energy consumption needed to meet the GDP level projected for 2025 will be much smaller (35.46 quadrillion Btu for the reference GDP) than the values actually recorded in the year 1990 (44.59). However, the non-fossil energy consumption in 2025 (118.8) increases much more than the actual recorded in the year 1990 when the efficiency index in 2025 is assumed to be at the level registered for the year 1990.     

Optimal military spending in the US: A time series analysis

This paper extends previous work on the optimal size of government spending by including nested functional decompositions of military spending into consumption and investment. Post World War II US data are then used to estimate nested non-linear growth models using semi-parametric methods. As expected, investments in military and non-military expenditure are both found to be productive expenditures with respect to the private production. Moreover there is little evidence to suggest that current military spending is having a negative impact on economic growth in the US, while civilian consumption only tends to have only a weak impact. This does not imply that society will necessarily benefit from a reallocation of more spending to the military sector, nor that it is the best way to achieve economic growth.     

Consumption,welfare, and stochastic population dynamics when technology shocks are (Un)tied

The impact of uncertainty on consumption and welfare seems obvious; because of the precautionary saving motive, higher uncertainty reduces consumption, and subsequently, deteriorates welfare. Recent several studies, however, find that this intuitive narrative is not necessarily true. This paper provides the analytical underpinnings for this. In the absence of technological progress, I find that the larger demographic shocks always reduce consumption, but improve the welfare of households. Moreover, when demographic shocks are negatively tied to technology shocks, there emerges an inverted-U relationship between the size of two shocks and consumption, and a U-shaped relationship between the size of two shocks and household welfare. These results are all characterized analytically in the framework of the stochastic two-sector growth model featuring the correlated Brownian motion process. The findings suggest that demographic policies should not be implemented with no reference to the state of technology.     

Stability through cycles

Economic variables like GDP growth, employment, interest rates and consumption show signs of cyclical behavior. Many variables display multiple cycles, with periods ranging in between 5 to even up to 100 years. We argue that multiple cycles can be associated with long-run stability of the economic system, provided that the cycle periods are such that interference is rare or absent. For a large sample of important variables, including key variables for the US, UK and the Netherlands, we document that this is indeed the case.     

Symbolic values, occupational choice, and economic development

Channeling human resources into occupations with high social productivity has historically been a key to economic prosperity. Occupational choices are not only driven by the material rewards associated with the various occupations, but also driven by the esteem that they confer. We propose a model of endogenous growth in which occupations carry a symbolic value that makes them more or less attractive; the evolution of symbolic values is endogenously determined by purposive transmission of value systems within families. The model sheds light on the interaction between cultural and economic development and identifies circumstances under which value systems matter for long-run growth. It shows the possibility of culturally determined poverty traps and offers a framework for thinking about the transition from traditional to modern values.     

Mixed public goods,consumption externality,and economic growth

Conclusion From the viewpoint of pure theory the basic contribution of this paper is in identifying both the consumption inducing and consumption displacing tendencies when mixed public goods are financed by income taxes. We have come to recognize that the provision of mixed public goods is conducive to economic growth if they are consumption displacing in nature.     

城乡居民消费差距与地区经济发展水平

经验观察发现,三十年来,我国省际城乡居民消费一直存在"经济发展越落后的地区,城乡居民消费差距越大"的现象。本文构建1978-2007年省际面板数据,基于不同模型的计量检验结果表明这种现象的存在,在经历了改革开放初期的"集体贫困"之后,这种现象在1980年代中期以后的二十年间显得尤为突出。而一些省份在经济发展到一定阶段后,城乡居民消费差距开始下降,这是未来发展的希望所在。本文还从社会发展、经济现状、政府行为、基础设施和对外贸易五个方面对影响省际城乡居民消费差距的因素进行了较为详细的考察,研究表明,加快农村基础设施建设、促进教育公平和完善农村社会保障体系等措施有助于迈向理想的共同富裕。     

Consumption risk, technology adoption and poverty traps: Evidence from Ethiopia

Much has been written on the determinants of technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests. Building on an explicit model, this is explored in panel data from Ethiopia. Historical rainfall distributions are used to identify consumption risk. Controlling for unobserved household and time-varying village characteristics, it emerges that not just ex ante credit constraints, but also the possibly low consumption outcomes when harvests fail, discourage the application of fertilizer. The lack of insurance or alternative means of keeping consumption smooth leaves some trapped in low return, lower risk agriculture, one of the mechanisms through which poverty perpetuates itself in agrarian settings.     

Household wealth, public consumption and economic well-being in the United States

Standard official measures of household economic well-beingin several countries are based on money income. The generalconsensus is that such measures are limited because they ignorecertain crucial determinants of well-being. We examine two suchdeterminants—household wealth and public consumption—inthe context of the US. Our findings suggest that the level anddistribution of economic well-being is substantially alteredwhen money income is adjusted for wealth or public consumption.Over the 1989–2000 period, median well-being appears toincrease faster when these adjustments are made than when standardmoney income is used. Adding imputed rent and annuity from householdwealth to household income increases measured inequality, whileadding public consumption reduces it. However, all three measuresshow about the same rise in inequality over the period.     

Oil consumption and economic efficiency: A comparative analysis of advanced, developing and emerging economies

This paper investigates the economic efficiency-oil consumption relationship in 42 countries during the period 1986-2006. In a first stage by using DEA window analysis countries' economic efficiencies are obtained. In a second stage an econometric analysis based on robust GMM estimators reveals an inverted ‘U’-shape relationship between oil consumption and economic efficiency. In order to capture heterogeneities among countries' development stages the analysis has been separated into two groups (advanced economies and developing/emerging economies). The results show that advanced economies have much higher turning points compared to emerging and developing economies. It appears that oil consumption increases countries' economic efficiency. In addition the consumption patterns of oil products and its derivatives have changed through years and among countries. The different turning points from the econometric analysis indicate the dependence of oil consumption in advanced economies (higher turning points) is driven mainly by household purchasing activities and their standards of living (transport, housing and water, food, etc.). Finally, it appears that oil consumption is the main driver behind the progress of industrialization and urbanization regardless of the country's development stage.     

新常态下内需拉动经济增长是否存在有效边界*

新常态下,中国如何维持经济中高速增长既是重点,也是难点。由于外需拉动型经济增长方式逐渐难以为继,扩大内需的重要性日益突出。然而,扩大内需真的是有效国策吗？投资和消费拉动经济增长,是否存在有效边界？基于此,本文通过构建面板门限模型,利用2012-2013年中国275个市级数据,对内需拉动经济增长是否存在有效边界问题进行了实证检验。研究结果显示：投资拉动经济增长确实存在有效边界,当投资率较低时,增加投资能够有效拉动经济增长,当投资率已经较高时,增加投资对经济增长的拉动作用将不再显著;消费拉动经济增长也存在有效边界,当投资效率较低时,增加消费会抑制经济增长,当投资效率足够高时,增加消费才能够有效拉动经济增长。\     

A model with endogenously determined cycles, discounting and growth

Summary. This article reexamines the role of consumption in growth and emphasises the external effects of aggregate consumption, viewed as consumption standards, as an additional impediment in the growth process. These external effects raise the productivity of the individuals and are positively related to their valuation of the future. Conditions are established under which this results in a marginal value of wealth that is an increasing function of consumption. This brings new types of multiple steady states, local indeterminacies and cyclical motions. Imposing extra homogeneity restrictions, balanced growth solutions with endogenous impatience emerge. The possibility of multiple convergent paths is univocally related to endogenous discount effects. A comparison with a benchmark planning economy indicates an excessive value for the rate of time preference and emphasises its insufficient adaptation to future utility in a stationary setting. Discrepancies along the transition path that rest on endogenous impatience versus fixed discount appear in a non-stationary environment when the competitive balanced growth solution is indeterminate.

Political democratization, economic liberalization, and growth volatility

This study empirically investigates the effects of political and economic liberalization on growth volatility using a difference-in-difference method for a sample of 158 countries over the 1970-2005 period. The results show that, when examined separately, economic liberalization leads to a significant reduction in volatility while democratization is not followed by a decrease in growth volatility. For countries that undertake only one liberalization, opening up the economy to international trade reduces volatility in growth; becoming a democracy, on the other hand, seems to increase macroeconomic instability. For countries that implement both political and economic liberalizations, no statistically significant effect on volatility is detected. These results serve to provide additional support for the policy recommendation that developing countries should liberalize their economy first and then consider political liberalization.     

Capital liquidity and residents’ consumption decision: An asymmetry analysis of economic prosperity

Among the current literatures that discuss the influence exerted on residents’ consumption behavior by capital liquidity, some often independently decide the demarcation point of the liquidity restriction that affects residents’ consumption behavior, without taking into account when the economy is flourishing whether residents will be influenced by the restriction of the liquidity that their consumption behaviors can not be fully carried out. We introduce a threshold model which varies according to the actual GDP and other financial indicators (money supply, average stock index and balance of bank loans) to discuss residents’ consumption behavior in China under different economic states. The empirical results show that when the economy flourishes or resuscitates, residents’ income of the same period have not notable influence on their consumption, which suggests that residents’ consumption behavior does not considerably change according to the fluctuation of the current income, but conforms with the constant income-life cycle hypothesis. Moreover, two estimated values 0.7504 and 0.8597, as economic boom measures, all fall in the boom stable stage—basically consists with the early-warning index of the macro-economy boom issued by National Bureau of Statistics of China. It shows that the macro-economic boom is not notablely influenced by capital liquidity, so is residents’ consumption behavior.
