The Role of the Real Estate Sector in the Structural Dynamics of the Chinese Economy: An Input–Output Analysis

Market‐oriented housing reforms and the rapid urbanization process have led to spectacular growth in the Chinese real estate sector (RES). However, the changes in the role played by this sector in the structural dynamics of the Chinese economy have not been examined sufficiently. Accordingly, we analyze the intersectoral structural changes to the Chinese RES, its linkages with the rest of the economy, and its growth sources, using four Chinese input–output tables from 2002 to 2017. We depart from existing work on the RES by using the causative matrix approach and structural decomposition analysis, and obtain three main results. First, the RES, which received little non‐RES feedback during the 2002–2007 period, has subsequently received much more substantial feedback. Second, the impact of the RES on China's economic growth stems mainly from its forward linkages. Third, the growth in the RES has been driven mainly by domestic demand expansion. Our results highlight that the Chinese RES, which plays a key role in value chains, is highly dependent on its own final demand and a fall in its demand would impede economic development. An important implication of these results is that developing the national economy by stimulating the RES would not be as effective as developing the RES through stimulating the national economy.     

An Exponential Family of Lorenz Curves

A new method for building parametric-functional families of Lorenz curves, generated from an initial Lorenz curve (which satisfies some regularity conditions), is presented. The method is applied to the exponential family since they use the exponential Lorenz curves as their generating curves. Several properties of these families are analyzed, including the population function, inequality measures, and Lorenz orderings. Finally, an application is presented for data from various countries. The family is shown to perform well in fitting the data across countries. The results are very robust across data sources.     

Patterns of economic change in the south‐west during the fifteenth century: evidence from the reductions to the fifteenths and tenths

The fifteenth century rebates to the fifteenth and tenth form a large body of evidence which has rarely been used to assess economic change. They were set by local commissioners who employed their knowledge of the conditions within their counties. In many cases the commissioners can be demonstrated to have applied the reductions in a thoughtful and proportionate manner, often revealing local economic conditions. There is considerable variation in their application between counties and their use is greatly enhanced when compared with other sources.     

Corporate Venture Capital and Its Contribution to Intermediate Goods Firms in South Korea*

Set by government, corporate, financial and individual sources, venture capitalists in Korea have adapted themselves to the new and uncertain venture capital market through stand‐alone and syndicated investments. The present study raises questions about whether various financial sources contributed differentially to their portfolio firms during the market boom of 2000. Results show that no single capital source showed better performance, and only corporate venture capitalists contributed to intermediate goods firms. The latter finding might reflect the unique ability of corporate venture capitalists to use vertical value‐chain linkages for their investments.     

‘Undercultivation’ and intensification in the Transkei: a case study of historical changes in the use of arable land in Nompa,Shixini

The large areas of abandoned arable fields in the communal areas of the Eastern Cape and KwaZulu‐Natal are often interpreted as evidence that rural people are no longer interested in farming and largely rely on off‐farm sources of income for their survival. However, this case study of land‐use practices in one village shows that farmers in the Transkeian coastal belt have not abandoned cultivation, but have shifted from the extensive cultivation of maize in distant fields to the intensive intercropping of maize and other food crops in fenced gardens adjacent to homesteads. Studies of yields from fields and gardens indicate that this has been an effective intensification strategy adopted by rural households to maintain yields in the face of shrinking resources and increasing risks. Evidence of changing land‐use practices is presented and the reasons for these changes identified and evaluated.     

Economic efficiency of synthetic motor fuels from natural gas

In this paper we study alternative ways to meet the demand for motor fuels growing in connection with the inevitable rise in oil prices over the next decade or two. One of these is to use natural gas as a motor fuel and as a raw material for synthetic motor oils. Calculation results of the comparative effectiveness of the gas-to-liquids (GTL) technology of motor fuel production from natural gas are presented. It is shown that these technologies look economically promising in countries, which have their own sources of natural gas, especially in small and remote gas fields.

Exploring the Impact of Energy Sources on Production,Inequality and Poverty in Simultaneous Equations Models for South Africa

Abstract: This work adapts per capita income, energy demand (sub‐group decomposed), inequality and poverty frameworks in a simultaneous equations setting to investigate the role of energy sources on per capita income, inequality and poverty in South Africa. It finds that energy sources (particularly electricity and diesel) are important in estimating production functions. Gasoline, kerosene and coal all exacerbate poverty, with the highest impacts on abject poverty. It is better to disaggregate energy sources in order to capture resource‐specific details. Redistribution efforts that focus on reduction of between‐group inequality can also moderate energy use since between‐group inequality tends to increase the demand for most energy sources. Public efforts are yielding fruits in this direction and should be encouraged. Access to energy sources like electricity, diesel and gas are crucial for productivity enhancement, but for them to yield significant anti‐poverty fruits, efforts must also target broadening capital access by the poor.     

Is it worth subsidising regional repertory theatre?

Subsidies to the performing arts are usually justified by referenceto externality and public goods arguments that are hard to quantify.We suggest that subsidies to theatres may be appropriate becauseof their inability to engage in spatial price discriminationto capture consumer surplus. For one major theatre, we use audiencedata and the Clawson-Knetsch travel cost method to assess theextent of consumer surplus and find that it exceeds the levelof subsidy received from public sources. On the basis of thisexample, current subsidy levels are justifiable even withoutrecourse to traditional externality/public goods arguments.     

Are the actual and intended sources of financial knowledge the same? Evidence from Japan

The recent prolonged period of low economic growth and low interest rates in Japan demands that Japanese households invest in risky assets to accumulate sufficient retirement savings. In so doing, they acquire financial knowledge on these risky assets, typically from financial experts or salespersons in financial institutions. However, they may not necessarily be content with their current sources of financial knowledge because depending on their stage in the life cycle, they require different types of financial knowledge, usually from a variety of sources. Unfortunately, because of limitations in the data available, few studies have investigated whether the actual and intended sources of financial knowledge are the same. To address this research gap, this paper uses a Japanese household survey from 2010 to 2017, which provides unique information on the actual and intended sources of financial knowledge, and obtains two interesting results. First, a household’s actual sources of financial knowledge typically differ from its intended sources. More specifically, 33 % of households choosing financial institutions and experts and 52 % of households choosing financial institutions as their actual sources have a different intended source. Second, the discrepancy between actual and intended sources appears to relate to household demographic characteristics. Among those households choosing financial institutions and experts as their actual source of financial knowledge, 14 % choosing financial institutions as their intended source tend to have a lower level of financial knowledge and educational attainment. These results suggest that they have some difficulty understanding the advice of financial advisers. Among households choosing financial institutions as their actual source of financial knowledge, 26 % choosing financial institutions and experts as their intended source tend to have a larger amount of financial assets, better financial knowledge, and a preference for investing in risky assets; however, they also tend to be younger. This suggests they might want to obtain financial knowledge from financial experts to purchase risky financial assets as they age. While the study does not provide any causal evidence, the results suggest that understanding the reasons for any discrepancy in the actual and intended sources of financial knowledge may help financial institutions provide better services to these customers.     

Integration into the South African core economy: household‐level covariates

In this analysis of household survey data, households' main income sources are used as indicators of integration into the South African core economy. The allocation of main income sources is studied as the outcome of households' demographic composition, geographic location and earners' characteristics. The emerging picture of household income generation is one that disputes the common perception of African households as raising their incomes from a multitude of sources. The majority of surveyed households rely to a large extent on a single source of income and a single income earner. Separate multinomial logit models are estimated for urban and non‐urban households where, in addition to the considerable association with non‐urban residence, prominent earner covariates of low‐integration income sources are female gender, old or young working age, and low levels of education. Both provincial location and within‐provincial, subregional locations display strong impacts. The study also finds associations between main income sources and households' demographic compositions that are compatible with findings both in studies on private transfer behaviour and in the growing literature on endogenous household formation in South Africa.     

Where there’s muck,there’s brass:1 the market for manure in the industrial revolution2

This article presents the first systematic analysis of off‐farm sources of nitrogen, such as urban and industrial waste, used in English agriculture during the industrial revolution, arguing that their use was widespread and intensive by 1700 and that there was only modest growth in their use up to 1840. It explains the pattern of use by supply and demand factors, and develops a new method to estimate the overall impact on wheat yields. It estimates that throughout the period 1700–1840 yields were 20 per cent higher than they would have been if no off‐farm manures had been used.     

The role of borrowing in crisis coping among ultra-poor households in rural Bangladesh

In this study, we show how decisions to borrow from different formal and informal sources are associated with different types of disasters. We estimate the associations between loans from different sources using monthly panel data from Northern Bangladesh. Households borrow from different sources to cope with disasters. The cost of loans, however, may vary by the source of funds. MFI loans, while low in terms of interest cost, usually require a savings deposit, loan or application fee, with a longer trip or waiting time. Hence, households resort to loans from informal sources to deal with crises. We estimate the impulse responses of loans from different sources, which clearly show a hump-shape centring for the months of disasters. Pre-emptive loans are associated only with partially anticipated shocks. Aggregate shocks also limit how much households can borrow from their local peers. Our findings rationalise the roles played by both informal and formal micro-loans in crisis coping in Bangladesh, where the market for microfinance is ubiquitous. The development of the emergency credit market and the introduction of insurance services in rural areas will require the non-price costs of such financial products to be lowered.     

Determinants of energy use in the informal food sector

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators.     

Technology,community and water supply: Case studies in KwaZulu and Transkei

The collection of water for domestic use In rural areas is a critical problem throughout the underdeveloped world. Traditional surface water sources are often far from the household, provide poor quality water and are susceptible to the effects of drought or dry periods. Village water supply schemes that have been implemented in KwaZulu and Transkei are evaluated according to their ability to provide an adequate and reliable supply of good quality water and reduce the burden of water collection. It is concluded that the inadequacy and unreliability of handpump schemes in KwaZulu, and the unreliability of windpump schemes in Transkei is due to inappropriate technology choices and the failure of water supply planners in these areas to address the community context of water supply schemes. The community considerations that must be taken into account include the establishment of communication links between villages and administrative services, the water needs of the community and the provision of village level servicing and maintenance facilities for appropriate water supply technologies.     

Use of registers and population censuses as sampling frames in Great Britain

The use of official data sources as sampling frames for numerous government surveys in the United Kingdom is described. "The great majority of these surveys use registers of various kinds as sampling frames. Some of these registers are intended to cover all addresses in the country in which there are private households. Other registers relate to specific sub-groups of the population. Each of the general registers has advantages and disadvantages but none is ideal for sampling purposes. In recent years nearly all samples required of the general population have been drawn, by automated means, from the Postcode Address File, although the balance of advantages of this system need to be continually monitored and evaluated." Reasons why the census is not often used as a sampling frame are considered.     

Russian enterprises in spring 2017: Slow restoration of investment activity against a background of economic stabilization

This paper has analyzed and commented on the results of the regular survey of Russian real sector enterprises, which was conducted by the Institute of Economic Forecasting of the Russian Academy of Sciences. The views of enterprises on the quality of economic policy of federal and regional authorities have been presented. Estimates have been obtained that reflect the dynamics of investment activity of enterprises and the dynamics of investment financing from various sources, as well as the need of enterprises to modernize production. The opinions of enterprises about the desirable dynamics of the ruble exchange rate are given. The current situation with the provision of enterprises with human resources has been reflected. Enterprises’ answers to questions about whether they have territorially detached subdivisions and their use of outsourcing have been considered.     

A model of an Indian village: A study of alternative sources of energy for irrigation

This study analyses the feasibility of various sources of energy for irrigation on the northeast Indian plains. In this region there is a large potential for further use of groundwater, and this paper examines the trade-off between the benefits to agriculture of irrigation, and the costs of the energy and equipment required for pumping.A linear programming model has been developed to predict the effects on agricultural production of several conventional and non-conventional technologies. Only small size pumps suitable for use by individual farmers or small cooperatives are considered.The results show diesel-fuelled pumpsets to have the largest net benefits. The general uncompetitiveness of the other technologies is due to the low energy requirements of irrigation in this area.     

服务外包有助于化肥减量吗?——来自荟萃分析的证据
