This study investigates mixed markets in which a social welfare-maximizing public firm and a private firm engage in behavior-based price discrimination (BBPD). Total of two cases are considered: one where domestic shareholders completely own the private firm and one where foreign shareholders...

This paper completely characterizes two public ownership solutions in convex production economies, known respectively as the Proportional Solution (PR), and the Equal Benefit Solution (EB), by adopting the axioms Moulin (1990a,b) discussed and introducing two other axioms, Pareto Independence...

This paper examines the implementation of two public ownership solutions in convex production economies with differentiable production functions. The two public ownership solutions we focus on are the proportional and equal benefit solutions. Two "natural" mechanisms which doubly implement the...

This paper examines the implementation of various solutions in differentiable concave production economies with one privately owned input, one output, and publicly owned production technology. The public ownership solutions we focus on are the Proportional Solution (PS) and the Equal Benefit...

This paper characterizes two public ownership solutions in convex production economies with multiple inputs and multiple outputs, known respectively as the proportional and equal benefit solutions (Roemer and Silvestre (1989)), by means of axioms of upper and unanimously lower bounds of welfare...

Tax changes are often announced before their implementation and are not permanent, but rather only temporary. Accordingly, R&D firms will optimally adjust their investment decisions to fit tax schedule changes. This study analyzes how changes in various tax rates relevant to corporate activities...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....

We investigate the incentive and the welfare implications of a merger when heterogeneous oligopolists compete both in process R&D and on the product market. We examine how a merger affects the output, investment, and profits of firms, whether firms have merger incentives, and, if so, whether...

This paper investigates an asymmetric duopoly model with a Hotelling line. We find that helping a small (minor) firm can reduce both social and consumer surplus. This makes a sharp contrast to existing works showing that helping minor firms can reduce social surplus but always improves consumer...
