This paper studies the welfare consequences of a government regulation that forces a patented equipment to be supplied by a number of independent producers. On the one hand, such a regulation hurts the value of a patent and therefore reduces activities in the R&D sector. On the other hand, the...

Special pairs of the utility functions and the production functions are used in this paper to uncover the transitional dynamics in a Lucas model of growth. The main findings are as follows: A continuum of equilibria exists if the external effect of human capital in goods production is...

This paper argues that an optimal deposit insurance scheme would allow the level of insurance coverage to be determined by the market. Based on this principle, the paper proposes an insurance scheme that minimizes distortions and embodies fairness and credibility, two essential characteristics...

In this paper, we provide a dynamic general equilibrium framework with an explicit investment-financing constraint. The constraint is intended as a reduced form to capture the balance sheet effects that have been widely regarded as an important determinant of financial crises. We derive a link...

In an endogenous-growth model, we consider alternative ways of providing public capital using distortionary taxes. We show that if the government provides the good, the resulting growth rate and welfare may or may not be higher than under laissez-faire. By contrast, if the government subsidizes...

This paper introduces a new class of utility function -- the power risk aversion.It is shown that the CRRA and CARA utility functions are both in this class. The implications of the PRA utility functions are explored in the context of growth theory. In particular, it is found that economies...

In this paper, we have obtained closed-form solutions in Cass-Koopmans growth models with heterogeneous agents. The relationship between the form of production function and the dynamics of income distribution is made explicit. We then use this relationship to determine what production structure...

Transitional dynamics in growth models have been subject to much attention recently. With a few exceptions, existing studies rely on computational techniques. This paper uses a set of examples to illustrate that qualitative insights on the transitional dynamics can be gained at the expense of...

Stackelberg differential games are useful settings in which optimal government policies can be studied. This paper argues that the analysis of these games involves a key technical issue. In particular, we question the necessity for optimality of one boundary condition invoked in existing...

This paper develops an understanding toward a theory of asset subscription. When a firm needs to raise cash from an asset that is too large or too risky for a single individual or financial institution so that an auction method is not applicable, the firm may use a subscription scheme. In this...
