A comparison of alternative methods of updating input-output coefficients

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.     

The dynamics of role interaction

Success in our respective business environments is not totally dependent on technical expertise; we must be able to also effectively interact with people. The necessity of successful leadership is assumed; however, we often fail to recognize the value of strategically subordinating ourselves to others. Both roles must be emphasized with the knowledge that preferred individual styles are valid.
