Explanation:

Here’s the thing—when we talk about the “planned” values of things like consumption, investment, and output, we’re in the land of intentions, not what actually ended up happening.

- Option 1: Ex post measures

- These measure stuff after it has already happened. Basically, it’s the “after the fact” scoreboard of what actually occurred, not what anyone intended.

- Option 2: Ex ante measures

- This is the correct answer. “Ex ante” literally means “before the event.” It’s about what people planned or expected to do—what they intended, not what ended up happening.

- Option 3: Ex pre measures

- This isn’t a standard term in economics. Not really a thing.

- Option 4: None of the above

- Clearly not the right fit, since ex ante is spot on.

So the planned value of variables is called the ex ante measure—Option 2. Simple as that.
