In 14 Rules For Working With An Expert Economist, expert witness Dr. Jerome M. Staller offers “rules” to follow that will help your economics expert witness do the best job he or she can for you and your client.
Never cross examine the opposing expert in deposition. Instead, inquire and learn. A deposition should not a warm-up for trial: You want to learn as much as possible and not tip your hand. Aggressive questioning during depositions is almost always counterproductive
Never hide information from your expert. Chances are, whatever facts you withhold from your expert will be known to the opposing side, which could lead to devastating cross.
