Microeconomics questions:

1. Is the relationship between inflation and changes in money quantity microeconomic or macroeconomic in nature? Justify your role.

2.What is the main explanation why conventional economics is unable to understand reality? Is it a lack of a practical theory or the conventional theory's flaws?

3. Which interval do you use for scope savings: the confidence interval or the estimation interval?

Economic forecasts are normally calculated using a combination of predictions in economics. Take, for example, scope economies. The proportion of cost savings from joint production compared to fully integrated costs is used to measure economies of scope once the cost function has been calculated. The above costs are conditional expectationsgiven that cost function coefficients equal to some fixed constants. Could anyone tell me that the interval for this estimate (economies of scope) is confidence interval or prediction interval?

4.How can I show lexicographic preferences in a graph? Assuming that only 2 goods exists.\
