C.Economic decision-makers base their future expectations on actual outcomes observed during recent periods. D.The indebtedness of the federal government reflects the cumulative impact of budget deficits and surpluses. 2.The index of leading economic indicators is an index composed of economic variables that tend to turn( up or down) prior to the beginning of a recession and turn (up/or down) prior to the beginning of a business expansion. 3.Are the implications of the rational and adaptive expectations hypotheses different in the short-run?

And yet, sometimes correlation is used. For example, in car insurance, male drivers are correlated with more accidents, so insurance companies charge them more. It would be impossible to actually test this for causation. Given the above, how do we balance this possibility of error with the need to have statistical results to inform our business decisions?

However, they were concerned about future growth because of changing diets of many consumers who had become more concerned about consuming milk-based products. The company had already added low-fat versions of the major products but the board members were concerned that this would not be sufficient to sustain their growth and profits. Some possibilities that were suggested for consideration included (1) setting up a new company to produce non-dairy-based products such as almond milk and other alternatives to cow milk. All the new products would have a healthy “spin” such as the White Wave company; (2) market expansion of their existing product lines into Mexico and Central America; (3) expanding their current product offerings by adding ice cream, high-end cheeses made from goat and sheep milk, and high-end milk-based candy; and (4) a combination of one or more of these alternatives. 1.
