There seems to be an error in your question. Budget deficit is when the government spending exceeds its revenue, yet your question makes no mention of expenses. However, it seems to be referring to something we call the "negative output gap", where actual output is lower than potential output. If this is the case, then the output gap is $100. (I suspect you omitted the million as no country, not even fictional, only produces $500.)
