CAN THE CARBONIZING DRAGON BE DOMESTICATED? INSIGHTS FROM A DECOMPOSITION OF ENERGY CONSUMPTION AND INTENSITY IN CHINA, 1987–2007

China has relied on energy to stimulate its booming economy. As a result, its share of world energy consumption rose to 17.3% in 2009 from 7.9% in 1978. Somewhat surprisingly, through 2000 its rate of energy consumption was about half its rate of economic growth. This trend changed after 2001 as energy consumption rose about 1.3 times more rapidly than did gross domestic product through 2005. Through heavy governmental influence, energy intensity subsequently reduced through 2007, but just marginally. This paper uses the structural decomposition approach to understand key drivers behind changes in China's energy intensity and its energy consumption from 1987 to 2007. In our model, energy intensity change was decomposed into five factors: changes in energy efficiency, changes in share of value added, changes in input structure, changes in consumption structure, and changes in consumption volume. This paper provides insights into how changes in China's economic structure, technology, urbanization, and lifestyle affect energy intensity and energy consumption.     

Effects of residential relocation on household and commuting expenditures in Shanghai, China

Over the past three decades, China's cities have undergone massive spatial restructuring in the wake of market reforms and economic growth. One consequence has been a rapid migration of urban residents to the periphery. Some movers have been forced out either by rising urban rents or government reclamation of their residences. Others have relocated willingly to modernized housing or for other lifestyle reasons. This article examines the effects of relocation to the urban edge on household well-being. It explores the factors underlying changes in housing and transportation costs as households move to the periphery. The research also examines whether those who moved involuntarily are affected differently from those who moved by choice. Results show that, relative to those who moved by choice, involuntary movers are disproportionately and adversely affected in terms of job accessibility, commute time, housing consumption and disposable income. The findings also show that, compared with higher-income households, lower-income groups are disproportionately affected in relation to housing costs, accessibility losses, disposable income and household worker composition. These results indicate that relocation compensation for involuntarily relocated households should be expanded to include more than just housing value: it should encompass urban location changes, household needs and relocation costs.     

Kinship and business: how entrepreneurial households facilitate business growth

Building on studies that have stressed the importance of context and the role of the family in business growth, this study explores the role of the entrepreneurial household in the process of business development and growth. We seek to understand how household strategy influences the development of new businesses, the ways in which household characteristics and dynamics influence business growth strategy decisions and how business portfolios are managed and developed by the household. To examine these questions, comparative case studies were undertaken drawing data from four entrepreneurial households located in remote rural regions of Norway and Scotland. The data reveal the role of the entrepreneurial household in the evolution of business creation and growth, examining the processual aspects of entrepreneurial growth, the interactions between business activities and entrepreneurial households and how business portfolios are developed in practice. Three analytical themes emerged from the analyses: the tightly interwoven connections between the business and the household, the use of family and kinship relations as a business resource base and how households mitigate risk and uncertainty through self-imposed growth controls. Although previous studies have viewed entrepreneurial growth largely as an outcome of personal ambition and business strategy, these results reveal the importance of the entrepreneurial household and the household strategy in determining business growth activities.     

Energy footprint of the city: Effects of urban land use and transportation policies

Urban land use and transportation policies have dramatic effects on the density and spatial distribution of residences in large cities. Effects of these policies have been analyzed using numerical urban simulation models. At the same time, the US Energy Information Administration’s Residential Energy Consumption Survey has allowed researchers to investigate the relation between household energy consumption and characteristics of housing units.This paper links these two lines of inquiry by demonstrating how simulation results on the implications of land use and transportation policies for the spatial form of cities can be used to compute implications for energy consumption. The resulting Urban Energy Footprint Model, “UEFM,” allows one to trace the implications of a change in land use zoning or transportation policy through its effects on housing markets and residential location to the resulting changes in energy use for residential and commuting purposes – i.e. to understand the energy footprint of transportation, housing, and land use policies. Accordingly, the UEFM provides, perhaps for the first time, a link between urban and energy economics, and can allow measurement of rebound effects of energy policies in a more general equilibrium context.     

Wealth Accumulation and Factors Accounting for Success

We use detailed income, balance sheet, and cash flow statements constructed for households in a long monthly panel in an emerging market economy, and some recent contributions in economic theory, to document and better understand the factors underlying success in achieving upward mobility in the distribution of net worth. Wealth inequality is decreasing over time, and many households work their way out of poverty and lower wealth over the seven year period. The accounts establish that, mechanically, this is largely due to savings rather than incoming gifts and remittances. In turn, the growth of net worth can be decomposed household by household into the savings rate and how productively that savings is used, the return on assets (ROA). The latter plays the larger role. ROA is, in turn, positively correlated with higher education of household members, younger age of the head, and with a higher debt/asset ratio and lower initial wealth, so it seems from cross-sections that the financial system is imperfectly channeling resources to productive and poor households. Household fixed effects account for the larger part of ROA, and this success is largely persistent, undercutting the story that successful entrepreneurs are those that simply get lucky. Persistence does vary across households, and in at least one province with much change and increasing opportunities, ROA changes as households move over time to higher-return occupations. But for those households with high and persistent ROA, the savings rate is higher, consistent with some micro founded macro models with imperfect credit markets. Indeed, high ROA households save by investing in their own enterprises and adopt consistent financial strategies for smoothing fluctuations. More generally growth of wealth, savings levels and/or rates are correlated with TFP and the household fixed effects that are the larger part of ROA.     

Analyzing Potentials for Reducing the Energy Requirement of Households in The Netherlands

The energy requirement of households represents a useful concept in studying energy use in relation to production structures and consumption patterns. Reduction potentials of the energy requirement for households provide insight on the possibilities for reducing energy use in the whole economy. We determine reduction potentials by means of implementing energy conservation options in an input–output model for calculating the household energy requirement. The implementation of a set of technical energy conservation options results in a reduction in the energy requirement of Dutch households by 55%. The reduction potential based on a set of demand-side options is 9%. The combination of both sets of conservation options results in a reduction potential of 59%. Therefore, by combining (sets of) options, some effects are cancelled out.     

Individual new energy consumption and economic growth in China

We document the one-way relationship between individual new energy consumption and economic growth in China through the autoregressive distributed lag (ARDL) model from 2004 to 2017. Our results show that individual new energy consumption has a positive effect on economic growth. Moreover, the urbanization rate, import and export trade volume and foreign direct investment all affect the individual new energy consumption in the short run. The outcome of the causality test reveals a one-way Granger causal relationship from individual new energy consumption to economic growth, from the urbanization rate, and from the import and export trade volume to new energy consumption.     

SOCIAL ACCOUNTING MATRIX FOR INDIA

This paper provides the latest Social Accounting Matrix (SAM) of the year 2003–2004 for the Indian economy with a wide variety of disaggregation for the Energy sector and the sectors that are relevant for environmental and climate policy evaluation. This SAM shows the interaction between production, income, consumption and capital accumulation. It can be used to provide an analysis of the interrelationship between the production structure of an economy and the distribution of incomes and expenditures of different household groups. In addition, it can be used for multiplier analysis to capture direct, indirect and induced impact on input use due to any exogenous changes in the economy. This SAM consists of 85 sectors of the economy, three factors of production and nine categories of occupational households. The Indian economy is becoming structurally biased towards capital intensive sectors, such as service and energy production. The energy production sector itself is the most energy intensive sector as of 2003–2004.     

Household factors and discrimination in housing consumption : Further developments in the analysis of tenure choice within housing careers

The decision of households regarding housing consumption should be viewed as decisions within an overall housing career. A model of household residential mobility is derived which may be empirically investigated through a generalisation of competing risk analysis. It is explained how the effects of omitted variables may be dealt with by means of a non-parametric characterisation of their multivariate distribution within a marginal likelihood framework. The problem of initial conditions is discussed in relation to the design of the analysis. The model is applied to the residence histories of a sample of households from the Michigan Panel Study of Income Dynamics

Demand for electricity in Nigeria: Some empirical findings

This paper presents the findings from an econometric model of Nigerian electricity demand. Electricity consumers are partitioned into three classes-namely. Residential, Commercial and Industrial. It shows that over the last two decades there has been tremendous increase in both the supply and demand for electric energy. Although supply has increased, it has not been able to keep pace with demand. Various explanatory variables that determine changes in demand are analysed for each of the three consuming sectors. The findings are as follows.(i) Per capital income, previous level of electricity consumption and urbanization are the most significant explanatory variables for the Residential sector's electricity consumption. The short and long-run income elasticities are found to be below unity, while whose of urbanization are above unity. The average price of electricity, though rightly signed, was found to be insignificant.(ii) As regards the commercial sector, the significant explanatory variables were previous level of electricity consumption, income, average price of electricity and urbanization. Urbanization was, however, found to be the most sensitive variable in respect to changes in the sector's electricity demand.(iii) Previous level of industrial electricity consumption and degree of urbanization were the main explanatory variables for changes in the Industrial sector's demand for electricity. Industrial output and income were not found to be significant variables in explaining changes in the Industrial sector's demand for electricity.     

Monetary policy,asset prices and consumption in China

This paper studies the wealth channel in China. Although the wealth channel has been found to be functioning in many advanced countries, its existence is yet to be explored in most emerging economies, also in China. In order to illuminate dynamics between monetary policy, asset prices and consumption, we use the structural vector autoregression method. The findings support the view that a loosening of China's monetary policy does indeed lead to higher asset prices. Furthermore, a positive shock to residential prices increases household consumption, while the role of stock prices seems to be small from the households’ point of view. Finally, we test the existence of the wealth channel more formally to find out whether those changes in asset prices that are caused by monetary policy are significant enough to increase consumption. In summary, the wealth channel remains weak but there are some signs of it via residential prices. The results are not that different from those attained for the advanced economies, where the size of the wealth channel has been found to be limited.     

Silence and Voice in Nigeria's Hybrid Urban Water Markets: Implications for Local Governance of Public Goods

This article highlights how the governance of the water sector affects the strategies and tactics urban residents use to gain improved access to water for household consumption in cities with limited networked infrastructure. A framework of exit, voice and loyalty (EVL) is used to characterize the actions household decision makers take in neighborhoods across metropolitan areas. In Nigeria, Lagos and Benin City are rapidly growing metropolitan regions with urban water markets competing with a state‐run utility. Scholars have documented informality and hybridity between state and non‐state actors, but there is less understanding of variables associated with citizen behavior in urban water markets across different types of households and communities. This article places Nigeria in the context of African mobilization around water provision, using interviews, observation and findings from fieldwork, household interviews and surveys undertaken between 2008 and 2015 to show how access to water is shaped by the interplay between state and non‐state sources of water. This access is filtered through differently regulated service providers and the perceived authority of each actor involved in water delivery, which can lead to what I call structural silence. Findings show the need for a grounded understanding of factors influencing voice and participation in local governance.     

城市化与能源消耗间关系实证研究

通过利用2000—2009年我国的省级面板数据,建立时间和空间双固定效应的面板空间杜宾模型,发现我国存在一条U形的城市化能耗库兹涅茨曲线,该曲线的转折点出现在城市化率约为24%的阶段。现阶段我国的城市化水平已经处在该曲线的右侧部分,表明如果我国的城市化率在今后仍不断提高的话,由城市化所导致的能耗将迅速增长。同时还发现城市化在我国能耗增长中的贡献比重较大,但对于在2003年出现的我国能耗迅速增加的拐点,从城市化的角度找不到解释。最后提出如果今后我国城市化率进一步提高,由能耗迅速增加所导致的城市发展的离心力达到一定程度,将会对我国的城市化格局产生重要的影响。     

A characterization of Ramsey equilibrium in a model with limited borrowing

This paper considers a one-sector economic growth model with several infinitely-lived heterogeneous households, who differ both in the discount factors as well as preferences over consumption. Unlike the extreme form of borrowing constraint observed in the classical Ramsey model, recently surveyed in Becker (2006), we allow limited borrowing by the households and prove the existence of a perfect foresight equilibrium. We also show that irrespective of production technology employed by the firms, the capital stock sequence converges to the steady state stock and from some time onward all impatient households are in the maximum borrowing state, whereas the most patient household owns entire capital stock and the debts of all other households.     

Technical Change in the Private Consumption Converter

The analysis of technological change is centered on the study of the evolution of technical coefficients in the input–output table. Complementary to this analysis, the household consumption expenditure matrix, relating consumption by commodities to consumption by purpose or by function, also incorporates some other aspects of technological change. Thus, the evolution in time of the coefficients of this consumption expenditure matrix will portray technological processes, implying substitutions between commodities to satisfy the different functions The substitution between consumption expenditure by functions is also to be taken into consideration, because it can influence, together with technological change, the use of commodities in the final demand. For Switzerland, a 1980–89 time series of household consumption expenditure matrices with 37 commodities and 58 functional consumption categories has been estimated using data from consumer expenditure surveys. In this paper, instruments generally applied to the analysis of changes in input–output technical coefficients are extended to these matrices, including methods that deal with biproportional processes of substitution.     

IMPACTS OF ECONOMIC REFORM ON RURAL-URBAN WELFARE: A GENERAL EQUILIBRIUM FRAMEWORK

This paper demonstrates how economic reform undertaken in a developing country will impact not only macroeconomic variables but also income distribution between different household groups, particularly between rural and urban households. Unlike the well-known link to macroeconomic variables, the path connecting economic reform with income of rural-urban households is more equivocal and thus demands an inquisition. The CGE model constructed in this study is designed to serve such a purpose. When applied to the Indonesian case, both the static and dynamic simulations indicate that the post-reform progress in the country's macroeconomic condition is likely accompanied by worsening—albeit slightly—household income distribution between income groups. The non agricultural sector appears to be the major beneficiary of the reform. From the dynamic simulation, a worsening distribution is also found between rural and urban areas. However, results of both simulations also show that improved poverty conditions are likely achieved following the reform.     

我国新能源消费与经济增长关系的实证分析

从实证的角度对我国新能源利用和经济增长的关系进行研究。首先,运用Granger因果关系检验分析发现,在短期内,新能源的消费是促进国内经济发展的一大动力。但是在长期,国内经济的高速发展也促进了新能源行业的快速发展。其次,将新能源和传统矿物质能源作为自变量建立了线性回归模型,结果表明新能源和传统矿物能源的消费均能促进我国经济的增长,但新能源对国内生产总值增长的贡献率大约是传统矿物质能源的24.7倍。因此,大力发展和探索新能源并逐渐用新能源代替传统能源,是保持我国经济高速增长的有效途径。
