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...

Estimation results obtained by parametric models may be seriously misleading when the model is misspecified or poorly approximates the true model. This study proposes two tests that jointly test the specifications of multiple response probabilities in unordered multino- mial choice models. Both...

This study considers uncertainty about the number of surviving children. Under prohibition of child labor, a higher survival probability of a child can increase opportunities for education investment as the fertility rate declines with a temporary increase in the number of surviving children....

This paper investigates the impact of low fertility on long-term capital accumulation and economic welfare. We find that the impact differs according to whether the low fertility arises from a decrease in the intensive or extensive margin of fertility. We show that an increase in the intensive...

In this study, we consider a one-period financial market with a monopolistic dealer/broker and an infinite number of investors. While the dealer who trades on his own account (with proprietary trading) simultaneously sets both the transaction fee and the asset price, the broker who brings...

The frequency of nominal wage adjustments varies with macroeconomic conditions, but existing New Keynesian models exclude such state dependency in wage setting, assuming time-dependent setting. This paper develops a New Keynesian model in which fixed wage-setting costs generate state-dependent...

This paper features the application of a novel and recently developed method of statistical and mathematical analysis to the assessment of financial risk: namely Regular Vine copulas. Dependence modelling using copulas is a popular tool in financial applications, but is usually applied to pairs...

In this paper, we explore a dynamic theory of investment and costly managerial turnover given agency conflicts between the firm manager and investors. We incorporate the possibility of the successive replacement of managers until the firm is finally liquidated, and develop a continuous-time...

Credit risk models should reflect the observation that the relevant value of collateral is generally not the average value of the asset over all possible states of nature. In most cases, the relevant value of collateral for the lender is its secondary market value in bad states of nature, where...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and analyze the optimal level of linear taxes on capital and labor income together with the optimal path of government debt. We show that in the presence of such risks it is beneficial to tax...
