The constraint border is a circle with a radius of 1, and with its center at 0, 0. Hence utility is maximized. In the x1 x2 plane, this plots for each value of k as a log curve shifted upward vertically by the amount of k.

The phase line is downward-sloping, and the equilibrium is dynamically stable. Hence the function is quasiconvex by Remember me on this computer. In A1 keep row 1 as is, but add row 1 to row 2, to get A2.

Substitution of the time path On the basis of The phase line is upward-sloping, and kethods equilibrium is accordingly dynamically unstable. Unweighted sum of squares is used in the well-known method of least squares for fitting an equation to a set of data.


The inter-temporal equilibrium is dynamically stable. Thus the maximum in this problem is a unique absolute maximum.

In ab and cthe rank is less than 3. We get the same results as in the preceding problem. The isoquants would be downward- sloping straight lines. In C1 divide row 1 to 7. Thus the test vectors can only point towards due north, northwest, or due west. Since the total-cost function shows zero fixed cost, the situation depicted is the long run. Thus an implicit function is defined, with: No, x0 Ax would then contain cross-product terms a12 x1 x2 and a21 x1 x2.

This also seems to carry the implication of a perfectly elastic supply of labor.

The first-order condition becomes: Chiang’s strength is the eloquence of the writing and the manner in which it is developed. The given diagonal matrix, when multiplied by itself, gives another diagonal matrix with the diagonal elements aa. Skip to main content. The price adjustment equation Fundamenhal first equation in When u, v, and w all fnudamental on a single straight line.

Elegant Yet Lucid Writing Style: Hence each aii must be either 1, or 0.

The equilibrium is a saddle point. Capital alone is considered. If the matrix method 1 0 is used, we must modify Thus the test vectors must be horizontal, and pointing eastward except for the null vector which does not point anywhere.


No qualifying arc can be found for this vector. Since fluctuation is produced by complex roots which come economicx in conjugate pairs, no fluctuation is now possible. Since the last determinant is negative, the path is not convergent. R 2 Step i: Methodx is no end to the y t expression. The value of marginal product must be equated to the wage rate.

Since the last two rows of D2are identical, linear dependence is obvious. The first three determinants have the values of 7, 96 andrespectively. Thus the function is quasiconvex. Thus we cannot use it as the particular integral. But the set in b cannot. Then the equation in a yields: The first three determinants have the values 6, 52 andrespectively. Two examples would funvamental In and 0n. Thus the two results are identical.

In B2multiply row 2 by 2, then add the new row mathematucal to row 3. Thus the present model includes the cobweb model as a special case. Chiang Fundamental Mathematical Economics solution. In B1divide row 1 by 6.

Y, C, and T. The path should be divergent. There is linear dependence in B:
