Using a small country model with habit-forming consumers and costly investment, we analyze equilibrium dynamics of the economy and derive empirical and welfare implications. The model can mimic some stylized facts: (i) a temporary increase in fiscal spending always deteriorates the current...

This paper estimates the contribution of net saving for each of twelve motives to overall household saving in Japan using micro data from Japanese Government survey and finds that the net saving for the retirement and precautionary motives, both of which are consistent with the life-cycle model,...

Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1995), we define several conditions of natural mechanisms in production economies, and proposed two types of natural mechanisms, that is, the quantity and price-quantity types.

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 studies the effects of 'price-matching' policies in the Bertrand oligopoly model. If one or more consumers incur enforcement costs to utilize price-matching clauses, the unique equilibrium outcome is the competitive one.

This paper establishes a B-core existence result for normal form TU games.

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...

In this paper, we analyse the saving behavior of the aged in Japan using household-level data from a 1992 survey conducted by the Ministry of Posts and Telecommunications.
