The income tax systems of most countries entail a favourable treatment of homeownership, compared to rental‐occupied housing. Such ‘homeownership bias’ and its consequences for a wide range of economic outcomes have long been recognised in the economic literature. Although a removal of the homeownership bias is generally advocated on efficiency grounds, its distributional implications are often neglected, especially in a cross‐country perspective. In this paper, we aim to fill this gap by investigating the first‐order effects, in terms of distribution of income and work incentives, of removing the income tax provisions favouring homeownership. We consider six European countries – Belgium, Germany, Greece, Italy, the Netherlands and the UK – that exhibit important variation in terms of income tax treatment of homeowners. Using the multi‐country tax benefit model EUROMOD, we analyse the distributional consequences of including net imputed rent in the taxable income definition that applies in each country, together with the removal of existing special tax treatments of incomes or expenses related to the main residence; thus, we provide a measure of the homeownership bias. We implement three tax policy scenarios. In the first, imputed rent is included in the taxable income of homeowners, while at the same time existing mortgage interest tax relief schemes and taxation of cadastral incomes are abolished. In the two further revenue‐neutral scenarios, the additional tax revenue raised through the taxation of imputed rent is redistributed to taxpayers, through either a tax rate reduction or a tax exemption increase. The results show how including net imputed rent in the tax base might affect inequality in each of the countries considered. Housing taxation appears to be a promising avenue for raising additional revenues, or lightening taxation of labour, with no inequality‐increasing side effects.  相似文献

The current availability of thousands of processors at many high performance computing centers has made it feasible to carry out, in near real time, interactive visualization of 3D mantle convection temperature fields, using grid configurations having 10–100 million unknowns. We will describe the technical details involved in carrying out this endeavor, using the facilities available at the Laboratory of Computational Science and Engineering (LCSE) at the University of Minnesota. These technical details involve the modification of a parallel mantle convection program, ACuTEMan; the usage of client–server socket based programs to transfer upwards of a terabyte of time series scientific model data using a local network; a rendering system containing multiple nodes; a high resolution PowerWall display, and the interactive visualization software, DSCVR. We have found that working in an interactive visualizastion mode allows for fast and efficient analysis of mantle convection results.  相似文献

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies.  相似文献

Homicide rates for South African children were estimated at double the global average in 2000. This article presents a secondary data analysis of the National Injury Mortality Surveillance System (NIMSS), with full coverage in four major metropolitan cities. Child homicide rates for 2001-2005 were calculated within the 0-4, 5-9 and 10-14 year age groups. The homicide rates were similar to the global pattern, with higher rates for boys, and among children aged 0-4 years than for older children. Poisson regression, accounting for city level clustering, was used to investigate age, sex and period effects in the homicide rate. The model indicated that the gender difference was more marked in the 10-14 year age groups (RR?=?2.17; 95% CI 1.97-2.38) than in the 5-9 year (RR?=?1.43; 95% CI 1.27-1.62) with the 0-4 year age group in-between (RR?=?1.80; 95% CI 1.55-2.10). These data confirm previous observations that fatal violence among children is a public health concern, but, given the high rates of homicide among South African adults and other competing public health problems, it is difficult to motivate for action to address the issue of violence against children. Nonetheless, there are sufficient indications that efforts to reduce childhood violence are urgently needed.  相似文献

Valuation effects and the dynamics of net external assets   总被引:1,自引:0,他引:1  
‘Valuation effects’ can imply that the traditional current account is an inaccurate measure of the change in the net foreign asset (NFA) position. This paper uses new developments in the analysis of portfolio choice in general equilibrium to investigate valuation effects in a two-country model. Broadly speaking, the valuation effects in the model correspond to those observed in the data. But there is a key distinction between ‘unanticipated’ and ‘anticipated’ valuation effects. Unanticipated effects can be large, dominating the movement in NFA, but anticipated effects arise only at higher orders of approximation and are small for reasonable parameterizations.  相似文献

Tony Atkinson is universally celebrated for his outstanding contributions to the measurement and analysis of inequality, but he never saw the study of inequality as a separate branch of economics. He was an economist in the classical sense, rejecting any sub‐field labelling of his interests and expertise, and he made contributions right across economics. His death on 1 January 2017 deprived the world of both an intellectual giant and a deeply committed public servant in the broadest sense of the term. This collective tribute highlights the range, depth and importance of Tony's enormous legacy, the product of almost fifty years’ work.  相似文献

It is generally believed foreign direct investment (FDI) has spillover effects which can affect the innovation capabilities of local firms in host countries. Comparatively little, however, is known about the contingent local contextual factors that influence how these FDI spillovers can be captured. Integrating the literature on FDI knowledge spillovers with that on inter- and intra-industrial externalities, we explore how local industrial agglomeration moderates the effect of FDI knowledge spillovers on innovation in the emerging market context of China. Empirical estimates, based on panel data of 1610 listed indigenous Chinese firms recorded between 2000 and 2010, indicate that such spillovers are more easily captured in industrially diverse settings. By contrast, industrial specialisation negatively moderates this relationship. Theoretical and practical implications are discussed.  相似文献

Live streaming allows streamers and viewers to watch, create, and share videos in real time on topics from gaming, shopping, and social channels to tourism and entertainment. It is distinct from earlier forms of social media in that it allows for real-time interaction and is extremely synchronous. That makes live streaming an important new area of enquiry. Yet live streaming platforms, streamers, and scholars lack an informed structure from which to build more holistic understanding and strategy. Following the theory–context–characteristics–methodology framework, we undertake a framework-based systematic literature review of 89 articles to source, review, and synthesize disparate findings in the arena of live streaming and live streaming commerce users' motivation and interactions. A dual stimulus–organism–response integrative framework is developed to further explore the characteristics of interaction and motivation factors. A future research agenda highlights areas of research focus that are critical next steps for scholars.  相似文献

One of the aims of wildlife tourism is to educate visitors about the threats facing wildlife in general, and the actions needed to protect the environment and maintain biodiversity. To identify effective strategies to achieve this aim, this paper examines participants’ memories of their wildlife tourism experiences and explores processes through which such experiences can lead to long-term changes in conservation behaviour. Findings are based on 240 visitors’ extended open-ended responses to a follow-up web survey administered approximately four months after a visit to one of four marine-based wildlife tourism venues in Southeast Queensland. Qualitative analysis revealed four levels of visitor response to the experience, implying a process involving what visitors actually saw and heard (sensory impressions), what they felt (emotional affinity), thought (reflective response), and finally what they did about it (behavioural response). Recommendations are provided for ways tourism managers and wildlife interpreters can maintain and strengthen these dimensions of memorable experiences in order to enhance visitor satisfaction and encourage visitors’ long-term adoption of environmentally sustainable practices.  相似文献
