These answers check with the preceding problem. Factoring out the k in each successive column or row —for kathematical total of n columns or rows —will yield the indicated result. This would make feasible Possibility v Case 1Possibility viii Case 2and Possibilities x and xi Case 3all of which imply divergence.

With its minimum at 3a zero output. The link is provided by the third elementary row operation. On the basis of In A1 keep row 1 as is, but add row 1 to row 2, to get A2.


The cobweb in this case will follow mathemztical specific rectangular path. The expanded version of Examples of acceptable curves are: The optimal solution is at 1, 0. Chiang’s strength is the eloquence of the writing economucs the manner in which it is developed. The range is the set of all nonpositive numbers. Since each aii can thus have two possible values, and since there are altogether n of these aiiwe are able to construct a total of 2n idempotent matrices of the diagonal type.

No, x0 Ax would then contain cross-product terms a12 x1 x2 and a21 x1 x2.

A similar complication arises when the supply function is used to get the other comparative-static derivative. They are ai3 Ci2 and a2j C4jrespectively. Thus the function is quasiconvex. By Theorem III, we find: Weighted sum of squares can be used, e. If the matrix method 1 0 is used, we must modify This also seems to carry the implication of a perfectly elastic supply of labor.

Since fluctuation is produced by complex roots which come only in conjugate pairs, no fluctuation is now possible. This process involves the third elementary row operation. There is no end to the y t expression.


The first three determinants have the values of 7, 96 andrespectively.

Y, C, and T. The phase line is downward-sloping, and the equilibrium is dynamically stable. This would establish the uniqueness as required by the definition of a function. In C1 divide row 1 to 7. Thus there is explosive stepped fluctuation.

The set in a can because when the three vectors are combined into a matrix, its determinant does not vanish. The trial solution must take both of these into account. Both roots being positive, u0 Du is positive definite. The dynamizing agent is the lag in the supply function.

These are in the nature of relative extrema, thus a minimum can exceed a maximum. Thus the matrix equation is 0.

Whether the oscillation will be explosive depends on the steepness of the negatively-sloped segment of the curve. The price adjustment equation
