ABSTRACTThe Industrial Ecology Virtual Laboratory (IELab) is a collaborative cloud-computing platform for compiling large-scale, high-resolution, enviro-socio-economic accounts based on multi-region input–output tables and for conducting integrated sustainability assessment projects. These include, for example, assessments of biofuels and low-carbon construction materials or high-resolution waste modelling. This contribution provides a structured review of IELab applications that were published in either peer-reviewed journal papers or in the form of conference proceedings. The main research question posed is ‘What are the specific features of IELab that were used in the research and could the research have happened without them?’ It is investigated whether the IELab has actually and truly enabled new research. A detailed analysis of IELab characteristics and their usage is presented. The results can help with the design of new research projects and inform existing and prospective users of the IELab about the options for academic research and practical applications. 相似文献

We examine the effects of the short‐selling ban, imposed by Australian regulators in the wake of the global financial crisis, on the trading of financial stocks. Our findings argue against commonly stated reasons for imposing short‐sale bans. We find no evidence that short‐sale restrictions provide support for stock prices or that they reduce volatility. Moreover, stocks subject to the short‐selling ban suffered a severe degradation in market quality. Controlling for the adverse effects of the financial crisis on markets, we show that short‐selling restrictions increase intraday volatility, reduce trading activity and increase bid–ask spreads. 相似文献

We study the pricing and hedging of derivative securities with uncertainty about the volatility of the underlying asset. Rather than taking all models from a prespecified class equally seriously, we penalise less plausible ones based on their “distance” to a reference local volatility model. In the limit for small uncertainty aversion, this leads to explicit formulas for prices and hedging strategies in terms of the security’s cash gamma. 相似文献

ABSTRACTIn this article, we identify and describe the sequential order-of-entry problem. The sequential order-of-entry problem arises when, after having identified a desirable set of country markets to enter, firms are unable (because of budgetary constraints), or unwilling (because of possible learning or strategic issues), to enter all at once. The question then arises whether some sequences to entering the desirable set of country markets are better than others? Answering this question is shown to be nontrivial. The article outlines a number of arguments for the existence of superior sequences to entering a set of desirable country markets, and develops normative and dynamic frameworks to aid in the identification and evaluation of sequences. 相似文献

ABSTRACTHistorians and economists have shown renewed interest in mercantilism over the last couple of years. From this interest, a dispute has arisen about whether mercantilism should be seen as an incoherent economic thought or if it is possible to ‘reconstruct’ its basic principles. In line with this latter attempt, this paper is intended to provide a materialist explanation for varying degrees of belief in shared mercantilist assumptions. My hypothesis is that belief in mercantilist assumptions is significantly dependent upon how economic and security issues materially interact in a given time and space, with uncertainty and insecurity profoundly favouring mercantilist dispositions in economic thought. To analyse this hypothesis, the paper sets the first steps for relating the credibility of mercantilism with changes in British economic and military history from the sixteenth to the nineteenth century. Section 3 presents ideas to further investigate this hypothesis. Section 4 concludes the paper. 相似文献

This paper examines the effect of various types of bank capital on the profitability and efficiency of conventional and Islamic banks. Our results show that higher quality forms of capital improve the profitability and efficiency for both systems although the results are stronger for conventional banks. The capital effect is more pronounced for large, too-big-to-fail, and highly capitalized banks. The results are robust across various subsamples, alternative profitability and efficiency measures, and different estimation techniques. 相似文献

Recent theoretical and empirical studies suggest that blockholders (shareholders with ownership ≥ 5 percent) exert governance through the threat of exit. Blockholders have strong incentives to gather private information and sell their shares when managers are perceived to underperform. To prevent blockholders from selling their shares and the firm from suffering a stock price decline, managers align their actions with the interests of shareholders. As a result of the greater manager‐shareholder alignment, managers' actions are more likely to be in shareholders' best interest, and consequently there is less need for managers to manipulate earnings. Consistent with these predictions from economic theory, we find evidence that as exit threat increases, firms have higher financial reporting quality. Theory also predicts that the impact of blockholders' exit threat on financial reporting quality (FRQ) should increase as the manager's wealth is tied more closely to the stock price, and this is what we find. Our study contributes to the research on the impact of shareholders on FRQ and to an emerging literature on the impact of blockholders in financial markets. Blockholders play an important role in managers' reporting outcomes through their actions as informed investors. 相似文献

SCREENING FOR A CHRONIC DISEASE: A MULTIPLE STAGE DURATION MODEL WITH PARTIAL OBSERVABILITY 下载免费PDF全文

We estimate a dynamic multistage duration model to investigate how early detection of diabetes can delay the onset of lower extremity complications and death. We allow for partial observability of the disease stage, unmeasured heterogeneity, and endogenous timing of diabetes screening. Timely diagnosis appears important. We evaluate the effectiveness of two potential policies to reduce the monetary costs of frequent screening in terms of lost longevity. Compared to the status quo, the more restrictive policy yields an implicit value for an additional year of life of about $50,000, whereas the less restrictive policy implies a value of about $120,000. 相似文献
