This Test Guideline lists methods for determining the density of liquids and solids, giving only a succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in SI units as kg/m3 at a specified temperature. Several methods are for liquid...

This Test Guideline lists methods for determining the density of liquids and solids, giving only a very succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in kg/m3. Several methods are for liquid substance only: hydrometer,...

This paper discusses some of the challenges algorithms present for both competition law enforcement and market regulation. In particular, the paper addresses the question of whether antitrust agencies should revise the traditional concepts of agreement and tacit collusion for antitrust purposes,...

Companies increasingly use algorithms to set prices and create or enhance new products and services. While algorithms can result in many efficiency-enhancing and pro-competitive effects, they can also be used by firms to restrict competition. Competition authorities should be aware of these...

What does PISA actually assess? This book presents all the publicly available questions from the PISA surveys. Some of these questions were used in the PISA 2000, 2003 and 2006 surveys and others were used in developing and trying out the assessment. After a brief introduction to the PISA...

This book describes the instruments underlying the PISA 2000 assessment. It introduces the PISA approach to assessing reading, mathematical and scientific literacy with its three dimensions of process, content and context. Further, it presents a sample of PISA 2000 tasks, and explains how these...

The current monetary policy framework in several Latin American countries, combining inflation targeting and a floating exchange-rate regime, has contributed to disinflation by anchoring expectations around low, stable levels. This paper uses co-integration analysis to estimate simultaneously a...
