This paper examines the role of compensation and risk committees in managing and monitoring the risk behaviour of Australian financial firms in the period leading up to the global financial crisis (2006–2008). This empirical study of 711 observations of financial sector firms demonstrates how the coordination of risk management and compensation committees reduces information asymmetry. The study shows that the composition of the risk and compensation committees is positively associated with risk, which, in turn, is associated with firm performance. More importantly, information asymmetry is reduced when a director is a member of both the risk and compensation committees which moderate the negative association between risk and firm performance for firms with high risk.  相似文献

Indoor environments are increasingly important spaces in contemporary three-dimensional cities. Handling these micro-scale spaces within the broader context of outdoor - urban environments is a significant challenge in transportation analysis and geographic information science. This complexity stems from the greater computational requirements, the specificity of indoor network data structures, as well as the inherent perceptual intricacies of 3D visualization. As built environments grow in size and in complexity, two-dimensional urban geography research reveals its limits. This paper advocates for 3D network-based urban research and showcases the feasibility of this approach for three specific types of urban analytical functionalities, namely route planning, spatial accessibility assessment, and facility location planning. The latter modeling functionality can be viewed as foundational elements for comprehensive network-based three-dimensional analytics of urban environments. The effectiveness of the data modeling scheme and of the integrated software application 3DCityNet is discussed through the three coupled geospatial modeling functionalities.  相似文献

The objective of this paper is to investigate the relationship between environmental performance and financial performance on a sample of 361 U.S. firms over the 2007–2016 period. We contribute to the literature by considering firms active in sustainable innovations by obtaining green patents. We also contribute to the literature by using disaggregated measures of environmental performance collected from the Bloomberg ESG database, including environmental disclosure score, greenhouse gas emissions, waste emissions and water use. Panel data regressions' results show that environmental transparency positively influences current accounting and stock market performance, but negatively influences the return on capital employed. Furthermore, lower pollution emissions tend to improve the current return on assets, while being harmful for the efficiency of long‐term capital employment at the same time. The empirical results also indicate that the Global Financial Crisis (2007–2010) increased the environmental transparency of firms with green patents but negatively impacted their price to earnings ratio. At the same time, lower waste disposal diminishes stock valuation while the opposite is true with water use. Taken together, our results suggest that environmental transparency and greenhouse gas emissions generally appear to be the most important environmental variables influencing financial performance, with increasing importance attributed to them by the market after the global crisis period.  相似文献

This article examines effects on major Australian macroeconomic and structural variables of simultaneous shocks to world oil and black coal prices. The illustrative numerical results have been produced with the short-run fuel substitution tax model, ORANI-LFT. The current version of that model reflects the Australian Governmet's pre-1988 oil regulatory framework, and the simulations reported in this study reflect the recent switch from significant dependence on crude oil levy revenue to petroleum products excise revenue. Empirical results show that combined world oil and coal price shocks lead to substantially different effects than would occur from an oil shock alone. A major implication of this, for a small open economy such as Australia, is that particular attention has to be paid to the interdependence of world energy market, both when analysing the effects of such shocks and when formulating appropriate macroeconomic and energy policy responses. It is also pointed out how the model could be modified for investigating effects under deregulated oil market regimes.  相似文献

This article aims to unbundle the influence of prevailing forestland rights institutions on the forest management behaviours of Vietnamese households. Based on a sample of 398 observations, we investigate the impact of two dimensions of forestland rights institutions (i.e. the formality and the duration) of two types of forest (i.e. production and protection forests) on two types of forest management behaviours (i.e. clearing and improving forest). We find that different dimensions of forestland rights institutions have different impacts on the forest management behaviour of households.  相似文献

This paper explores a model of group membership formation in which agents decide to join or not multiple social groups. The membership formation process induces a bipartite graph structure with social groups listed on one side and agents listed on the other side. Among members of multiple social groups, we consider two decisive types of agents: the grand star and the mini star. The former type is the unique agent in a society who participates in all social groups. The latter type includes agents who participate in more than one, but not all, social groups such that every social group pair has one and only one common member. We analyze the efficiency and stability conditions of group membership formation, and we establish sufficient conditions under which a connected graph that contains either a grand star or a set of mini stars becomes the unique strongly efficient and stable graph.  相似文献

In the new millennium, cities have become an emerging force among new forms of subnational climate governance. Of interest is how cities act unilaterally and directly in this new climate politics via the provision of relevant tools. Since metropolitan planning strategies have been considered as important mechanisms for achieving urban sustainability in this period, this research has sought to investigate the importance of these master plans in the delivery of urban responses to climate change. For this purpose, the study has employed a qualitative research methodology with the application of a comparative case study and the progression of a conceptual framework for evaluating climate policies in metropolitan plans of two selected cities—London and Melbourne. The study's results suggest that both the ‘London Plan’ and ‘Plan Melbourne’ incorporate critical elements to enhance climate governance, including the promotion of coordination principles, innovative technologies, a participatory planning approach and a long‐term planning scale. However, the review identified a consistent omission of key principles as identified through the proposed matrix for analysing the climate policies of a city's government, which include risk assessment tools, monitoring systems, distribution, impact frame and accountability. Moreover, the research also revealed the lack of vertical integration in policy formulation and implementation of ‘Plan Melbourne’. Our study suggests that a city's governance structure influences the way it undertakes its climate actions and the potential efficacy of these on a metropolitan scale.  相似文献

We investigate a centrally planned, infinite horizon, single good economy in which new knowledge is generated in a separate R&D sector with government subsidy. The rate of growth of new ideas is assumed to be linear in the amount of labor devoted to R&D. Perpetual growth in per capita output and consumption is sustained by the spillover effects of knowledge creation. Using an isoelastic social welfare function and a general production function, the unique balanced growth path is characterized and the conditions for balanced growth to take place derived. In analyzing standard balanced growth, we demonstrate that so long as physical capital and knowledge grow at some arbitrarily constant rates along an optimal time path, the two rates must necessarily be equal. Using a Cobb–Douglas production function, the dynamic evolution of the economy is explicitly described in closed form for each state and control variables. In particular, it is shown that the economy either (i) attains the balanced growth path from the initial time, or (ii) converges monotonically to the balanced growth path. An asymptotic balanced growth path along which labor input in manufacturing tends to zero in the long run is ruled out by the tranversality condition on knowledge.  相似文献

This article reviews developments in the Stock Trading Centre (STC) in Ho Chi Minh City, Vietnam, the main stock market in the country, since its start in 2000. It presents information about developments in the number of stocks traded, trading activity and stock-price developments. This article focuses on the question whether the market is weak-form efficient. An important element of the investigation concerns the possible bias of the results caused by the thin trading that characterizes the STC. Stock-market returns are corrected for this. The main conclusion is that the STC is not efficient in the weak form.  相似文献

Chronic wasting disease (CWD) is a prion disease that affects deer, elk and other cervid wildlife species. Although there is no known link between the consumption of CWD affected meat and human health, hunters are advised to have animals from CWD affected areas tested and are advised against consuming meat from CWD infected animals (Government of Alberta 2010). We model hunter response to the knowledge that deer in a wildlife management unit have been found to have CWD in Alberta, Canada. We examine hunter site choice over two hunting seasons using revealed and stated preference data in models that incorporate preferences, choice set formation, and scale. We compare a fully endogenous choice set model using the independent availability logit model (Swait in Probabilistic choice set formation in transportation demand models. Dissertation, MIT, 1984) with the availability function approach (Cascetta and Papola in Transp Res C 9(4):249–263, 2001) that approximates choice set formation. We find that CWD incidence affects choice set formation and preferences and that ignoring choice set formation would result in biased estimates of impact and welfare measures. This study contributes to the broader recreation demand literature by incorporating choice set formation, scale and temporal impacts into a random utility model of recreation demand.  相似文献
