Simultaneous estimation after selection and ranking and other procedures: The negative exponential case

We considerk (≥2) independent negative exponential populations with unknown location parameters and unknown but equal scale parameter. We incorporate the existing purely sequential and three-stage sampling procedures for selecting the “best” population and study the asymptotic second-order characteristics of the proposed fixed-size simultaneous confidence regions for the location parameters constructed after selection and ranking. Some direct estimation procedures have also been discussed.

Using an historical account book as a teaching tool

Historical account books from the 18th and 19th centuries are valuable historical documents reflecting the activities of individuals many years ago and shedding light on the way they lived. Such books can be used to teach accounting. From our experience, these books serve to motivate students to learn about the basic aspects of the accounting process. Students are curious about how a book of this nature was prepared, what specific purposes it served, and how it is similar to and different from modern account books. Using these books can also foster interdisciplinary instruction, i.e. accounting and history. Both subject areas relate to an account book. Attempting to explain and understand transactions requires some knowledge of the history of the period in which the book was prepared. In this study, specifics are given on the instructional approach we recommend. While a book of this kind can be used in different ways and degrees in a variety of accounting courses including introductory financial, intermediate, and advanced at the undergraduate and graduate levels, we focus in this case study on its use in introductory financial accounting.     

PRICE-BASED MEASUREMENT OF FINANCIAL GLOBALIZATION: A CROSS-COUNTRY STUDY OF INTEREST RATE PARITY

Abstract.   We characterize the relationship between ex post exchange rate depreciation and the interest differential for both developed and emerging market economies. The measured ex post uncovered interest differentials in terms of both levels and absolute values are then related to a set of variables that capture macroeconomic and policy conditions. We find that a wide diversity in the coefficient relating depreciations and interest differentials can be attributed to differences in inflation volatility, financial development, capital account openness, legal development and the nature of the exchange rate regimes. The robust results are mainly found in the emerging market country grouping.
