are interest rate options important for the assessment of interest rate risk
Research Papers in Economics, 2009Co-Authors: Caio Almeida, Jose VicenteAbstract:Fixed income options contain substantial information on the price of interest rate volatility risk. In this paper, we ask if those options will provide information related to other moments of the objective distribution of interest rates. Based on a dynamic term structure model, we find that interest rate options are useful for the identification of interest rate quantiles. A three-factor model with stochastic volatility is adopted and its adequacy to estimate Value at Risk of zero coupon bonds is tested. We find significant difference on the quantitative assessment of risk when options are (or not) included in the estimation process of the dynamic model. Statistical back tests indicate that bond estimated risk is clearly more adequate when options are adopted, although not yet completely satisfactory.

Social Science Research Network, 2008Co-Authors: Caio Almeida, Jose VicenteAbstract:Fixed income options contain substantial information on the price of interest rate volatility risk. In this paper, we ask if those options will also provide information related to other moments of the objective distribution of interest rates. Based on dynamic term structure models within the class of affine models, we find that interest rate options are useful for the identification of interest rate quantiles. Two three-factor models are adopted and their adequacy to estimate Value at Risk of zero coupon bonds is tested. We find significant difference on the quantitative assessment of risk when options are (or not) included in the estimation process of each of these dynamic models. Statistical backtests indicate that bond estimated risk is clearly more adequate when options are adopted, although not yet completely satisfactory.

questioning the trust law duty of loyalty sole interest or best interest
Social Science Research Network, 2005Co-Authors: John H LangbeinAbstract:The duty of loyalty requires a trustee to administer the trust solely in the interest of the beneficiaries. Any transaction in which the trustee has an actual or potential interest violates the sole interest rule, no matter how beneficial the transaction to the beneficiaries. This Article develops the view that a transaction should not give rise to liability merely because the trustee also benefits. Sometimes beneficiaries are better off when a transaction also benefits the trustee. Corporation law has wholly abandoned the sole interest rule, preferring a rule that permits a conflicted transaction that satisfies disclosure and fairness standards. Important changes have been undermining the trust law sole interest rule. The grievous procedural inadequacies of the equity courts that gave rise to the rule have now been overcome. The rise of professional trusteeship has required that the sole interest rule be abridged to permit trustee compensation. As trusteeship has increasingly become a branch of the financial services industry, major exceptions to the sole interest rule have been recognized to facilitate trustee-provided financial services. The rationale for these exceptions is that they benefit trust beneficiaries by promoting integration of functions and economies of scale. This Article contends that the exceptions are wiser than the rule they modify. The duty of loyalty should be reformulated to prefer the best interest rather than the sole interest of the beneficiary. A conflicted transaction should continue to be presumed to violate the duty of loyalty, but rebuttably, not conclusively. The trustee should be allowed the defense that the transaction was in the best interest of the beneficiaries.

using Pinterest to stimulate student engagement interest and learning in managerial accounting courses
Journal of Accounting Education, 2018Co-Authors: Amy Foshee Holmes, Stephanie J RasmussenAbstract:Managerial accounting is a course that typically suffers from a lack of student engagement. This paper presents a social media-based assignment that can increase student interest in and understanding of managerial accounting, particularly for English as a second language (ESL) students. For the assignment, students used Pinterest to share Internet-based resources with their class. The students were also required to comment on Pinterest “pins” created by their classmates. The assignment encouraged students to be engaged and active learners in the course, build interest in the managerial accounting topics covered, and develop a deeper understanding of managerial accounting by utilizing outside resources and real world examples. A survey of students’ attitudes indicates that approximately two-thirds of the students perceived the assignment had a positive impact on both their engagement in the course and their ability to better understand course topics. Student responses also suggest that the Pinterest assignment had some impact on their interest in managerial accounting. Mean survey responses were significantly more favorable for ESL students compared to non-ESL students.

using Pinterest to stimulate student engagement interest and learning in managerial accounting courses
Social Science Research Network, 2017Co-Authors: Amy Foshee Holmes, Stephanie J RasmussenAbstract:This paper presents a social media-based assignment that was utilized in both introductory and advanced managerial accounting courses at the undergraduate level. For the assignment, students used Pinterest to share Internet-based resources with fellow members of their class. The students were also required to comment on Pinterest “pins” created by their classmates. The assignment encouraged students to be engaged and active learners in the course, build interest in the managerial accounting topics covered, and develop a deeper understanding of managerial accounting by utilizing outside resources and real world examples. A survey of students’ attitudes indicates that approximately two-thirds of the students perceived the assignment had a positive impact on their engagement in the course as well as their ability to better understand course topics. Student responses also suggest that the Pinterest assignment had some impact on their interest in managerial accounting. Mean survey responses were significantly more favorable for English as a second language (ESL) students compared to non-ESL students.

categorizing user sessions at Pinterest
International Conference on Big Data and Smart Computing, 2019Co-Authors: Dorna Bandari, Shuo Xiang, Jolie Martin, Jure LeskovecAbstract:There are many different ways for individuals to use a given Internet application. By recording and analyzing detailed logs of user in-application activity, we identify patterns of behavior that reflect distinct use cases. Not only does this lead to a better understanding of user intent, but also generates important insights with actionable product and business outcomes. In this application oriented paper, we study the problem of user session classification, where the goal is to discover categories of user in-application behavior using event logs, and then consistently label user sessions on an ongoing basis. We develop a practical three-step approach which uses clustering to discover categories of sessions, builds classifiers to label new sessions, and finally performs daily classification in a distributed pipeline. An important innovation of our approach is replacing a set of events identified as long-tail features with a new feature that is less sensitive to product experimentation and logging changes. This allows for robust and stable identification of session types even though the underlying application is constantly changing. We apply the approach to Pinterest sessions and verify the results with a user survey. Our solution classifies millions of user sessions daily and leads to actionable insights that guide business decisions relating to product design, monetization, and growth.

categorizing user sessions at Pinterest
arXiv: Human-Computer Interaction, 2017Co-Authors: Dorna Bandari, Shuo Xiang, Jure LeskovecAbstract:Different users can use a given Internet application in many different ways. The ability to record detailed event logs of user in-application activity allows us to discover ways in which the application is being used. This enables personalization and also leads to important insights with actionable business and product outcomes. Here we study the problem of user session categorization, where the goal is to automatically discover categories/classes of user in-session behavior using event logs, and then consistently categorize each user session into the discovered classes. We develop a three stage approach which uses clustering to discover categories of sessions, then builds classifiers to classify new sessions into the discovered categories, and finally performs daily classification in a distributed pipeline. An important innovation of our approach is selecting a set of events as long-tail features, and replacing them with a new feature that is less sensitive to product experimentation and logging changes. This allows for robust and stable identification of session types even though the underlying application is constantly changing. We deploy the approach to Pinterest and demonstrate its effectiveness. We discover insights that have consequences for product monetization, growth, and design. Our solution classifies millions of user sessions daily and leads to actionable insights.
