Making expert systems work for you
Article Abstract:
An expert system is a computer program that consists of three components: a knowledge base, an inference engine, and a user interface. Criteria for identifying potential applications for expert systems include: problems that cannot be solved with algebraic solutions, fields in which only a few expensive experts are available, the data needed to make decisions are not related clearly to the solution, problems that can be solved in a diagnostic or interpretive format, and bodies of knowledge not subject to rapid change. Barriers to implementing expert systems include: the expense and complexity of the equipment needed to run expert system programs, the expense of custom-designing each program, and difficulties in finding the appropriate expert to help build the system.

Developing a spreadsheet to calculate duration
Article Abstract:
An electronic spreadsheet can be used in calculating and evaluating bonds. Duration is the weighted average time necessary to recover the interest and principal from a fixed income investment. Duration data can be useful in revealing the volatility of a bond's price resulting from interest-rate changes, and in determining how to protect a fixed-income portfolio from interest-rate risk. When setting up the spreadsheet, required information, including years to maturity, payment periods per year, and principal amount, should be put in a separate area.

Discount brokers: how investors have fared
Article Abstract:
Individual investors have benefited from the deregulation of the securities industry. The cost of investing has declined, commission fees have been reduced, and investors can choose from a wider range of products and services, without having to pay for services they do not want or need. The savings on commission costs from using discount brokers vary, depending on the discount broker used and the type of transaction. Full service brokerages may be more advisable for investors who lack the time or expertise to make their own investment decisions.
