This paper introduces a bubbly asset into the Matsuyama (2007) model with credit market imperfections and multiple technologies and shows that there can exist multiple bubbly steady states and bubbles may cause underdevelopment traps by preventing the adoption of high productivity technology.

We investigate an overlapping generations model (OLG) model in which agents who live for two periods receive idiosyncratic productivity shocks when they are old. We show that a combination of lump-sum and linear capital taxes can always Pareto-improve the allocation, that is, it can raise the...

Using a simple framework of Cooper and John (1988) and Cooper (1999), this paper derives the conditions under which overconfidence and underconfidence of agents lead to Pareto improvement. We show that an agent’s overconfidence in a game exhibiting strategic complementarity and positive...

Extending the Grossman [12] model of health capital into a stochastic one, we analyze how the presence of Knightian uncertainty about the efficacy of health care affects the optimal health investment behavior of individuals. Using Gilboa and Schmeidler's [11] model of maxmin expected utility...

Unless free international lending/borrowing is allowed, domestic saving equals domestic investment and hence saving and investment taxes have the identical effect, as is the case in a closed-economy context. However, if it is allowed, households can accumulate foreign assets besides domestic...

This paper constructs a small open economy version of the Kiyotaki and Moore (1997) model along the line developed by Kasa (1998) and derives a closed-form solution of the current account dynamics. Using the solution, a null hypothesis of no credit constraints is tested for the Japanese economy....

Extending the Kim (1989) model of endogenous labor specialization to an overlapping generations model with an endogenous technology choice, we show in this paper that, when the market size and the fixed costs associated with the technologies with labor specialization are small, the growth...

Specialization patterns in a dynamic Heckscher-Ohlin (HO) model with endogenous capital accumulation are examined in the presence of free international lending and borrowing. Without free international lending and borrowing it is known that, whereas the less (time-) patient country decumulates...
