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 discusses and develops "non-welfaristic" arguments on distributive justice, mainly basing upon J. Rawls and A.K. Sen, and formalizes, in cooperative production economies, "non-welfaristic" distribution rules as game forms. First, it conceptualizes Needs Principle that the distribution...

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...

This paper synthesizes, in one Leontief economic model, the arguments of exploitation and unequal distribution of wealth by Roemer (1982,1986) and of the power relationship between employers and employees concerning the labor extraction by Boyles and Gintis (1988,1990). The author introduces the...

In this paper, we consider and formulate, in cooperative production economies, a social procedure for choosing fair allocation rules, basing it upon the argument of the Rawlsian two principles of justice (Rawls (1971)). First, we adopt Sen's Capability (Sen (1980, 1985)) index to evaluate...

We examine auction data to determine if bid rigging presents in procurement auctions for paving works in Ibaraki City, Osaka, Japan. We first show that sporadic bidding wars are caused by the participation of potential "outsiders." Assuming that the ring is all-inclusive if the auction is not...

This paper examines empirically some of the reasons why Japanese manufacturing firms frequently fail to satisfy concavity conditions of the cost function. We focus on the "bubble period" in the 1980s when land was in great demand for reasons related to both production and speculation, and land...

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...

We consider a gtenure-clock problemh in which a principal may set a deadline by which she needs to evaluate an agent's ability and decides whether to promote him or not. We embed this problem in a continuous-time model with both hidden action and hidden information, where the principal must...
