First, we investigate which type of the liability law that protects nuclear power plants against catastrophe is socially optimal. We show that when a firm with a few funds is managed under the strict liability, maximization of social welfare is impossible since the firm may not cope with the...

We develop a macroeconomic model in which liquidity plays an essential role in the production process, because firms have a commitment problem regarding factor payments. A liquidity crisis occurs when firms fail to obtain sufficient liquidity, and may be caused either by self-fulfilling beliefs...

We study the investment timing problem where two firms that compete for investment preemption know in advance the time at which the economic condition changes. We show that the so-called Bad News Principle applies to the leader firm’s investment decision near maturity in many cases. This...

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...

In this paper we consider the estimation of a dynamic panel autoregressive (AR) process of possibly innite order in the presence of individual effects. We utilize the sieve AR approximation with its lag order increasing with the sample size. We establish the consistency and asymptotic normality...

The purpose of the paper is to discuss ten things potential users should know about the limits of the Dynamic Conditional Correlation (DCC) representation for estimating and forecasting time- varying conditional correlations. The reasons given for caution about the use of DCC include the...

City size distributions are known to be well approximated by power laws across many countries. One popular explanation for such power-law regularities is in terms of random growth processes, where power laws arise asymptotically from the assumption of iid growth rates among all cities within a...

This paper examines the B¨uhlmann’s equilibrium pricing model (1980) in the presence of transaction cost and derives the (multivariate) Esscher transform within the framework under some assumptions. The result reveals that the Esscher transform is an appropriate probability transform for the...

This paper has two primary purposes. First, we fit the annual maximum daily rainfall data for 6 rainfall stations, both with stationary and non-stationary generalized extreme value (GEV) distributions for the periods 1911-2010 and 1960-2010 in Taiwan, and detect the changes between the two...

This paper examines how impatience interacts with inequalities in economic development. In a society of intrinsic inequality, we show that (i) poor households tend to benefit more from positive shocks under decreasing marginal impatience (DMI) than uner constant marginal impatience (CMI) and...
