This study investigates the potential impact of climate change and armed conflict on inequality in Sub-Saharan Africa (SSA). The system-GMM for a panel of 35 SSA countries is employed using annual data from 1997 to 2018. The empirical results indicate that armed conflict and climate are major drivers of inequality in SSA. The direct impact of the two determinants is more than the indirect impact. Also, the impact of armed conflict is more than the climate change. The coefficients of population growth, output growth, unemployment, natural rent, exchange rate and inflation rate are significant positive predictors of inequality in the SSA. The study advocates for a multidisciplinary inclusive growth strategy that prioritises the climate change reversal, de-escalation of armed conflict, population control, reduction of the unemployment rate and increasing informal sector productivity, to promote inclusive growth and reduce inequality. However, sequencing the policy targets relative to the magnitude of their impact on inequality is extremely crucial. 相似文献

Since the formation of the Peoples’ Republic of China (PRC) in 1949, the broad field of accounting education in China has undergone many changes in the context of a dramatically changing sociopolitical environment. The institutional mechanisms in Chinese university accounting education are examined in this paper, principally through a re-reading of the historical experience since 1949. We utilize an institutional theory frame to examine how action in the regulative, normative, and cultural-cognitive pillars have shaped accounting education from its heavily political orientation in the early years of the PRC to a more internationalized university accounting education system that has begun to take shape in contemporary China. We seek to contribute a contextualized understanding of contemporary China's accounting education, while adapting and extending the role of institutional theory in explaining education changes more broadly. 相似文献

It has been commonly observed that tropical countries tend to suffer from intense corruption and underdevelopment. This study provides an explanation for this long-standing disparity across the world based on variation in the intensity of ultraviolet radiation (UV-R). The central hypothesis is that UV-R is positively associated with the (historical) prevalence of eye diseases, which significantly shortens work-life expectancy as a skilled worker. This helps shape the worldwide distribution of corruption by affecting the incumbents' window of opportunity. Using data for up to 139 countries, I consistently find empirical support for the positive relationship between UV-R and corruption. The main findings withstand accounting for numerous alternative explanations for international differences in corruption levels. Employing individual-level data from the World Values Survey, I document suggestive evidence that exposure to UV-R is linked to surveyed respondents' tolerance towards corrupt activities. Furthermore, a subnational analysis for China lends credence to the cross-country evidence. 相似文献

A significant decline has been experienced in the quality of life of people living in cities due to the deterioration of the ecological balance, decrease in biodiversity, together with air, noise and water pollution occurring as a result of population growth and urbanization. All of these factors have triggered global warming, which is one of the biggest problems in recent years. For this reason, the climate has become one of the most important factors in urban design works. The purpose of the present study is to determine the microclimatic contribution of urban open spaces to the city in the context of climate-balanced physical planning criteria, and to propose an analytical model, which may constitute a basis for planning and design works. Firstly, the climatic requirements of the city of Gaziantep were examined by creating bioclimatic comfort maps. In the following stage, monthly wind roses were created by determining the dominant wind directions for the summer and winter seasons. Optimum location and directions that were balanced with climate were determined and slope and aspect maps of the area, land use types and area selection criteria were also created. In light of these data, ecological compatibility and feasibility maps were prepared. In the feasibility map, the temperature and humidity maps were created with ENVI-met, which is a climatic simulation software, for the most extreme days in an area where there were residential areas and educational institutions, multi-storey residential areas, working areas, social and open green areas, and afforestation areas. The results that were obtained with the simulations were subjected to Regression Analysis to determine the relationship among the climate parameters and the design criteria. As a result, the increase in the quantity of urban green spaces and equality on the spatial distribution of these areas will improve bioclimatic comfort (the warmest hour of the hottest period regression analysis’ result is β= -0.384). It has been determined that planning high-density plantation in green spaces and selecting dense and broad-leaved plants will provide a cooling effect (on average 2−3 °C less). Furthermore, adding more green spaces in cities will increase the thermal comfort within city blocks, especially where high-rise buildings are common. It is confirmed that high-rise buildings cause thermal stress (the warmest hour of the hottest period regression analysis’ result is β = 0.472). Hardscapes have a negative effect on the temperature (the warmest hour of the hottest period regression analysis’ result is β = 0.425). In addition to these data, it was found that the mean radiant temperature values, instead of temperature values, would yield more accurate results in microclimate analyses and interpretations. 相似文献

Institutional fields are not static, they undergo times of fragmentation and times of settlement. Neo-institutional research has long explained the settlement of fields as either the effect of political manoeuvring of actors, or of discursive activity influencing cultural codes, narratives and symbols. But can these processes really be considered in isolation? In this paper, we propose to adopt a comprehensive view on fields’ dynamics, one that embraces the interaction of political and discursive manoeuvring to explain how fragmented fields manage to settle. To do so, we build on the Gramscian concept of hegemonic practices as discursive and political processes that integrate cultural equivalence among actors with political alliances based on aligned interests. Hegemonic practices align actors in a new historical bloc (a new settlement). Through this lens, we interpret the case of the Italian State steel privatization (1984–1995) and propose a process model explaining what yields fields’ dynamics from fragmentation to settlement. The model highlights the action of diffused agency in field dynamics, thus overcoming the obsolete challenger/incumbent view, and the need of becoming a historical bloc for alliances to stabilize a field. 相似文献

Motivated by the rising consensus that corporate engagement in climate change actions holds the key for society's transition into environmentally resilient economy, the study examines whether a firm's commitment to climate change action and its carbon risk exposure shape the firm's debt financing policy. Based on insights drawn from signaling, corporate reputation, and agency theories, we develop models that link corporate commitment to climate change actions and a firm's carbon risk exposure with its debt financing decisions. Using data drawn from S&P 500 companies, for years 2015 to 2019, we find a robust evidence that firms that engage in higher levels of commitment to climate change actions issue a higher proportion of debt with longer terms to maturity, even after controlling for their carbon risk exposure. However, we do not find a robust evidence corroborating an association between firms' carbon risk exposure and their debt financing policy. These findings are consistent with arguments that high-commitment firms enjoy positive reputation, better credit rating, and reduced agency and information asymmetry costs, allowing them to gain easier access to long-term debt markets. 相似文献

Anxieties over the potential impacts of climate change, often framed in apocalyptic language, are having a profound, but little studied effect on the contemporary Western urbanscape. This article examines the ways in which current theorizations of ‘ecological gentrification’ express only half the process, describing how green space is used for social control, but not how ecology is used as a justification regime for such projects. As urbanites seek out housing and living practices that have a lower environmental impact, urban planners have responded by providing large-scale regeneration of the urbanscape. With the demand for this housing increasing, questions of inequality, displacement and dispossession arise. I ask whether apocalyptic anxiety is being enrolled in the justification regimes of these projects to make them hard to resist at the planning and implementation stages. The article shows that, in capitalizing on collective anxiety surrounding an apocalyptic future, these projects depoliticize subjects by using the empty signifier, ‘Sustainability’, leading them into an immuno-political relationship to the urbanscape. This leaves subjects feeling protected from both responsibility for, and the impacts of, climate change. Ultimately, this has the consequence of gentrification coupled with potentially worsening consumptive practices, rebound effects and the depoliticization of the environmentally conscious urbanite. 相似文献

We develop a forward-looking profit model to estimate the depreciation rates of business R&D capital. By using U.S. government data between 1987 and 2007, and the newly developed model, we estimate both constant and time-varying industry-specific R&D depreciation rates. The results comprise a set of R&D depreciation rates for major U.S. high-tech industries. They align with the main conclusions from recent studies that the rates are in general higher than the traditionally assumed 15 percent and vary across industries. The relative ranking of the constant R&D depreciation rates among industries is consistent with industry observations and the industry-specific time-varying rates are informative about the dynamics of technological change and the levels of competition across industries. Lastly, we also present a cross-country comparison of the R&D depreciation rates between the U.S. and Japan, and find that the results reflect the relative technological competitiveness in key industries. 相似文献

We provide empirical evidence on the labour market impacts of COVID-19 in the UK and assess the effectiveness of mitigation policies. We estimate the relationship between employment outcomes and occupational and industrial characteristics and assess the effects on consumption. Seventy per cent of households in the bottom fifth of the earnings distribution hold insufficient assets to maintain current spending for more than one week. We compare the effectiveness of the UK's Coronavirus Job Retention Scheme and of Economic Impact Payments in the US. The EIPs are more effective at mitigating consumption reductions as they have full coverage, depend on household structure and are higher for low-income workers. 相似文献
