This volume addresses a variety of topics where economic concepts are intertwined with important legal and policy issues in North America and Europe. Five articles involve analyses of competition issues, including economic plus factors in price fixing cases, the impact of refusals to deal on product quality, and market definition for intermediate goods. There are also articles on legal -cost allocation and patent hold ups, the strategic use of licensing commitments, and cost sharing's impact on bankruptcy. Finally, there is a very detailed empirical analysis of the monetary cost of raising children, which has implications for policies of the United States Department of Agriculture.
