For a pure-exchange, closed economy without storage, Eagle and Domian (2005) and Koenig (2011) derive similar but different equations of Pareto-efficient risk sharing. We confirm that both equations are correct. We also generalize and reinterpret Koenig’s equation. We find that Koenig’s...

This article has developed a new model of welfare dynamics under imperfect information or imperfect competition by introducing a new concept of ‘inefficient welfare equilibrium’. It assumes that an economy can be split into two virtual parts. For one part the fundamental welfare theorems are...

Searching for sustainable regional trade agreements (RTAs) for East Asia, we quantitatively evaluated the likely impact of proposed East Asian RTA strategies─(i) the AFTA (a being-left-alone strategy), (ii) an ASEAN Hub RTA (a hub-and-spoke type of overlapping RTA strategy), (iii) the AFTA vs...

The hypothesis is that Pareto and Kaldor-Hicks Efficiency have an aspect of sustainability in relation to inequality. The analysis finds efficient situations reached increasing inequality as diminishing in the long term effective demand in a larger measure than counterbalancing increases thanks...

This paper shows that a Nash equilibrium consisting of strategies of choosing a Pareto inefficient transition path is selected by households even without frictions as a result of the revealed government failure in supervision of financial markets. The Pareto inefficiency causes the generation of...

The application of Nash bargaining solution to profit division in negotiation between opencast lignite mine and power plant has been discussed. Different proposals of status quo point usage and ways of its determination for profit sharing both in strategic and tactical/operational negotiation...

The conventional search and matching model has been criticized for its inability to explain large cyclical volatility in the vacancy-unemployment ratio without ad hoc assumptions of wage rigidity. This paper presents a mechanism of such volatility without assuming wage rigidity by showing that...

In this paper we apply the complete analysis of a differentiable game (recently introduced by the author) to determine possible suitable behaviors (actions) of tourism firms during strategic interactions with other tourism firms, from both non-cooperative and cooperative point of view. To...
