What is the effect of government reforms (unspecified) that decrease customer's confidence about their future wages (analysed using the IS-LM model)?

I think that less confidence about future wages will cause people to save more (rise in MPS or equivalently a fall in MPC). This causes the autonomous component of the IS curve to decrease, and the gradient to become flatter.

Using the following model:

$$Y = \frac{1}{(1-c_1-d_1)}\cdot A - \frac{d_2}{(1-c_1-d_1)}\cdot i $$

According to my textbook, however, this is incorrect. It suggests that the IS curve is shifted to the right, leading to an increase in $i$ and $Y$.

Could somebody kindly shed some light on this for me?

  • $\begingroup$ The textbook is Blanchard Macroeconomics European 2nd Edition. The question is from the online revision software, however. There's no further information in the question, although on reflection it could have been related to a chapter on small open economies, in which case I agree with their answer naturally. $\endgroup$
