Environmentally Important Inter sectoral Flows: Insights from Main Contributions Identification and Minimal Flow Analysis

For the analysis of economic interdependences form an environmental perspective, a condensation of the information contained in input–output (IO) tables is desirable, but without much loss of the quantitative dimension. For the case of total energy requirements, main contributions identification is presented as an approach that allows a partitioning of total energy requirements by production layers and (final) energy-consuming sectors. For this purpose, a mixed monetary-energy IO model and a partitioning procedure are used. In addition, minimal flow analysis as a graphical method is used to detect importnant energetic interconnections. Environmentally Important Intersectoral Flows     

Which past returns affect trading volume?

Anecdotal evidence suggests and recent theoretical models argue that past stock returns affect subsequent stock trading volume. We study 3,000 individual investors over a 51 month period to test this apparent link between past returns and volume using several different panel regression models (linear panel regressions, negative binomial panel regressions, Tobit panel regressions). We find that both past market returns as well as past portfolio returns affect trading activity of individual investors (as measured by stock portfolio turnover, the number of stock transactions, and the propensity to trade stocks in a given month). After high portfolio returns, investors buy high risk stocks and reduce the number of stocks in their portfolio. High past market returns do not lead to higher risk taking or underdiversification. We argue that the only explanations for our findings are overconfidence theories based on biased self-attribution and differences of opinion explanations for high levels of trading activity.     

Cyclical correlations, credit contagion, and portfolio losses

We model aggregate credit losses on large portfolios of financial positions contracted with firms subject to both cyclical default correlation and direct default contagion processes. Cyclical correlation is due to the dependence of firms on common economic factors. Contagion is associated with the local interaction of firms with their business partners. We provide an explicit normal approximation of the distribution of portfolio losses. We quantify the relation between the variability of global economic fundamentals, strength of local firm interaction, and the fluctuation of losses. We find that cyclical oscillations in fundamentals dominate average losses, while local interaction causes additional fluctuations of losses around their average. The strength of the contagion-induced loss variability depends on the complexity of the business partner network.     

Bank Efficiency, Risk-Based Capital, and Real Estate Exposure: The Credit Crunch Revisited

The turbulent real estate market during the early 1990s coincided with the implementation of risk-based capital standards for commercial banks. In this study we use non-parametric linear programming techniques to identify the lost real estate lending due to bank inefficiency. Inefficiency may arise from one of three sources: risk-based capital standards which constrain bank real estate lending, inefficiency stemming from managerial oversight of real estate lending, and scale inefficiency which arises from banks not operating at constant returns to scale. The results indicate that the lost real estate lending associated with risk-based capital standards averaged 2.7% of total bank assets. However, banks could compensate by exercising better managerial oversight of real estate lending and by operating at constant returns to scale.     

Impacts of e-Commerce and Enhanced Information Endowments on Financial Services: A Quantitative Analysis of Transparency, Differential Pricing, and Disintermediation

Some implications of e-Commerce financial services firms are becoming clear. The web drives transparency, and increases the information endowment of all market participants. It is harder to manipulate customers' behavior, or to overcharge them. Transparency drives differential pricing. Not all customers can or should be charged the same prices. Transparency reduces the viability of cross-subsidies between customers can or between products. The differential pricing enabled by the web transforms distribution channels, and enables direct distribution and alternative forms of distribution. Some intermediateraries may be bypassed altogether, while others may rapidly lose their best, most profitable, and previously most loyal customers.     

Balancing the dual mandate of conservation and visitor use at a Canadian world heritage site in an era of rapid climate change

Abstract

National parks in Canada operate under the dual mandate of conservation and visitor use, which involves balancing ecological integrity and nature-based tourism activities. Climate-induced environmental change may increase the existing tension between conservation and visitor use as major tourism resources located in protected areas (PAs) are projected to undergo large-scale changes. This study draws upon the behavioural approach, scenario planning, and landscape visualizations to examine the relationship between climate change impacts, visitor perceptions, and visitor experience management at the Athabasca Glacier in Jasper National Park, Canada. Four tourism development scenarios defined by two management drivers (ecological integrity and visitor demand) with corresponding storylines and visualizations were developed for 2050. The visualized scenarios were presented to visitors (n?=?304) in a survey to understand potential implications on visitor satisfaction. The results suggest that park managers need to find a balance between ecological integrity and visitor use in a way that ensures commercialized tourism development is limited, educational material is prioritized, and ecological integrity is maintained. While understanding the behaviour of future tourists is complex, it is a critical component of climate change adaptation planning and decision-making processes that needs to be prioritized by policymakers and PAs managers.
