1. The problem asks about the effects on production and bond prices when there is an identical and simultaneous decrease in autonomous consumption and autonomous taxes. 2. In macroeconomics, autonomous consumption is the part of consumption that does not depend on income, and autonomous taxes are fixed taxes independent of income. 3. A decrease in autonomous consumption reduces aggregate demand, tending to decrease production. 4. A decrease in autonomous taxes increases disposable income, tending to increase consumption and aggregate demand, which tends to increase production. 5. Since the decreases are identical and simultaneous, their effects on aggregate demand and production tend to offset each other, leading to little or no net effect on production. 6. Regarding bond prices, a decrease in autonomous consumption reduces demand for bonds (as people consume less and save more), which tends to increase bond prices. 7. A decrease in autonomous taxes increases disposable income, which can increase demand for bonds, also tending to increase bond prices. 8. Overall, the simultaneous identical decreases tend to have no significant effect on production or bond prices. Final answer: No effect on production nor the price of bonds.
