The rate of time preference (RTP) has traditionally not been regarded as an important source of economic fluctuations. In this paper, I show that it is an important factor influencing economic fluctuations because households must have an expected RTP for the representative household (RTP RH) to...

Keynes’ original intention in introducing the concept of a liquidity trap was to explain the reason why persistent large amounts of unutilized resources were generated during the Great Depression. This paper shows that this type of phenomenon cannot be explained in the framework of a...

This paper theoretically examines a way out of the euro crisis based on a model of inflation acceleration and differentials. The conclusion is that, unless more advantaged states (e.g., Germany) systematically transfer a necessary amount of money to less advantaged states (e.g., Greece) in every...

This paper presents a more realistic endogenous time preference model, incorporating the property that impatience decreases as consumption increases. The model overcomes a serious drawback of the existing model, which needs the assumption of increasing impatience. The new model is applied to the...

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 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...

Strategies for trade liberalization when the rates of time preference are heterogeneous across countries are examined in the framework of endogenous growth. The paper argues that the best strategy for a country with the relatively higher rate of time preference is the strategy of free trade with...

This paper examines the mechanism of persistent inflation differentials, current account imbalances, and fiscal deficits in the euro area by constructing a multi-country model in which the optimization behaviors of governments as well as those of households, firms, and the European Central Bank...
