Under this approach, several samples are pooled, and the pooled samples are first tested. If the pool tests negative, then the lab would have successfully tested many samples while consuming only the resources needed for a single test. If the pooled sample tests positive, then each sample that comprised the pool is individually tested. In this context, an important question for people in the field is “Given a certain overall infection rate among the population, what is the optimum pool size so that we can minimize the overall number of tests for a given number of individual samples?” In this paper, we derive this number both empirically and analytically. We also address the related question “Given a certain pool size, what is the maximum infection rate for which we can still gain in terms of the number of tests?”</p> 2021-01-01T00:00:00+00:00 Copyright (c) 2021 The Effect Of Corporate Governance And Corporate Strategy On Family Firm Performance In Indonesia 2021-04-15T19:00:44+00:00 D. Agus Harjito Adhitya Rechandy Christian Santoso Carl B. McGowan, Jr. <p>This paper analyzes the influence of corporate governance and corporate strategy on the performance of family owned or controlled firms listed on the Indonesia Stock Exchange. The Corporate Governance proxy is Family Ownership and Independent Commissioner, and Corporate Strategy proxies are Diversification and Compensation Strategy of Directors. This study uses a sample of 70 companies that are family owned or controlled companies listed on the Indonesia Stock Exchange (IDX) from 2014 to 2018. Data analysis was performed using multiple linear regression methods. The results of this study indicate that family ownership has a significant negative effect on company performance (ROE). While diversification and compensation strategy of directors have no effect, firm performance is measured by ROE.</p> 2021-01-01T00:00:00+00:00 Copyright (c) 2021 International Evidence On Currency Adjusted Stock Indexes 2021-04-15T19:11:22+00:00 Terrance Jalbert <p>Recent literature examines currency value adjusted indexes. The extant research examines U.S. stock indexes as adjusted for the value of the U.S. dollar and the value of gold. The literature examines only U.S. stock indexes. This paper extends the existing literature by examining currency adjusted stock indexes from eight countries. The analysis includes daily closing data from 1993-2016. The results show that currency adjusted indexes produce significantly different return distributions than original indexes. Further, currency value changes explain as much as 31 percent of total wealth changes, a result substantially higher than previously reported for U.S. currency adjusted indexes. The combined evidence indicates that currency value changes impact total wealth changes more for international indexes than for U.S. indexes.</p> <p>&nbsp;</p> 2021-01-01T00:00:00+00:00 Copyright (c) 2021
