Most ETFs are still passively managed funds that track equity indexes. The newer ones, however, are increasingly complex, often focussing on narrow sub-sectors of the market, non-equity asset classes, or enhanced directional plays. Some allow investors to expand and fine-tune a traditional asset allocation based on core equity exposure; others, such as leveraged or inverse ETFs, are used to improve portfolio risk-adjusted performance. As such, we must be aware that while ETFs may continue to offer the market valuable investment opportunities, just like with other financial products there are also distinct risks associated with these investments that need to be fully understood. What are they? How can they be used? and What do we need to know to protect ourselves before we invest? Are only a few of the many questions answered by this book. To effectively wade into ETFs' increasing complexity, this book opts for a multi-author approach. Gathering many experts gives the reader the benefit of exposure to all aspects of ETF features and use. Never before has this many expert opinions on ETFs been collected in one place. This book incorporates practitioners' perspectives on the challenges facing ETF investors as well as their insights on building ETF portfolios using the latest investment trends and strategies. Topics covered range from the established to the most recent cutting-edge work, making this book a must-have, not only for professionals wanting to brush up on the fundamentals of ETFs, but also for those who are more advanced in their use of these financial products and are looking for an edge in an increasingly competitive market.
Managed Care and the Treatment of Chronic Illness is a unique presentation of available research in the treatment and outcome of care for the chronically ill patients in managed care settings. Chronic illnesses require frequent and specialized treatment for patients - anathema to the short-term and cost-effective objectives of MCOs. Professor Christianson, aided by five expert collaborators, addresses MCO strengths and issues in treating these patients, looks at research results comparing treatment in MCOs versus fee-for-service medicine, and considers the various management techniques and programs to deliver care to enrollees with chronic conditions. Finally the authors critically address the anticipation of the future for this growing population and research: the changes in the MCO environment this population will demand for successful care and the suggested directions for future research.
The central emphasis in the book is on the transaction and the constraints that its architecture imposes on a discussion of monetary theory and policy. Because of their comprehensiveness and discipline the flow-of-funds accounts are the ideal vehicle for theorizing about real and financial interaction. Such int- action can best be understood when real and financial transac- tions are expressed in a common flow dimension. Each decision by economic agents is seen as two-ended in terms of markets: one market supplies the source of funds and the second market absorbs these funds. A matrix of interdependent markets is featured throughout the theoretical discussion. Credit markets, and the bank credit market in particular, become the source of disturbance in the theoretical model, but the necessary involve- ment of the money market is also stressed. Theories of finan- cial instability and crisis now receiving considerable attention are part of the more general theory of the flow of funds. The rationale for the monetary authority to target credit rather than the monetary aggregates emerges from the analytical discus- sion. A flow-constrained analysis clarifies interest-rate deter- mination, provides a helpful format for discussing equilibrium and disequilibrium, integrates credit markets with the familiar IS-LM framework, and identifies a class of missing equations in macro-monetary theory. The prototype of the missing equations is an equation explaining monetary dissaving in terms of a series of arguments only one of which will be the stock of real balances or real wealth.
