It is theoretically clear and may be verified empirically that efficient financial markets can make it less necessary for policy to try and offset the welfare effects of labour income risk and unequal consumption dynamics. The literature has also pointed out that, since international competition...

The existence of equilibrium is a test of the internal consistency of an economic model. In any model with domestic moneys and dividend-yielding assets, the first question is: will money be dominated by assets in equilibrium? In cash-in-advance models domestic moneys always have positive...

In the first chapter, we consider the logistic regression model with an integrated regressor. In particular, we derive the limit distributions of the nonlinear least squares (NLS) estimators and their t-ratios. It is shown that the NLS estimators are generally not efficient. Moreover, the...

This dissertation includes three essays on decision-making by boundedly rational economic agents. The first essay deals with decision-making by firms where decision-making is costly. The other two essays deal with decision-making by individuals. Taken together, the last two argue that...

The thesis shows two possible ways in which intergenerational redistributions associated with a reform from a comprehensive income tax to a direct consumption tax are affected when the standard models studying this phenomenon are extended.The usual models studying the welfare impact of a direct...

The dissertation is composed of three papers on institutions and development, with special focus on Vietnam. The first paper, "Club Good and Contract Enforcement," investigates the contract enforcement power of the communities whose members participate voluntarily. By investing in club goods,...

We lay a unified foundation for a theory of general equilibrium by proving the existence of an equilibrium for a grand model which covers all the well-known general equilibrium models under the convexity and continuity assumptions. The grand model allows an economy to have an extended list of...
