It's certain that it's a bit more difficult to determine whether an investment or an expenditure will have a long-term or short-term impact when we don't know the areas that will be targeted. I assume you're referring to the $70 billion to $100 billion mentioned in the fall economic statement. It's very difficult to determine precisely what will be the short- and longer-term impacts on the economy of these expenditures without knowing exactly where they will go. Not all spending is created equal when it comes to generating economic growth and generally social welfare.
