This paper presents a politico-economic model that includes a mutual link between life cycle earnings mobility and redistributive politics. The model demonstrates that when an economy features a high opportunity of upward mobility and high risk of downward mobility, it attains a unique...

This paper investigates which of the two countries \resource-rich or resourcepoor\ gains from capital market integration and capital tax competition. We develop a framework involving vertical linkages via resource-based inputs as well as international fiscal linkages between resource-rich and...

This paper presents a politico-economic model that includes a mutual link between earnings mobility and redistributive politics. The model demonstrates that an economy attains a unique, unskilled-majority equilibrium where unskilled, lowincome agents support a low, rather than a high,...

This paper analyzes an endogenous choice problem with regard to tax instruments in a capital tax competition model. Considering a symmetric and two-region model of tax competition, where each region is allowed to choose either unit or ad valorem tax, we show that selecting unit tax as a policy...

This paper presents a politico-economic model including a mutual link between earnings mobility and redistribution policy affected by human capital risk. The model demonstrates that a low-risk economy produces multiple equilibria: an unskilled- majority equilibrium with lower mobility and higher...

This paper investigates the interactions between preemptive competition and leverage. We find that the second mover always leaves the duopoly market before the first mover, although the leader may exit before the followerfs entry. We also see the leverage effects of debt financing increasing...

We develop a dynamic model in which a firm exercises an option to expand production with cash balance and costly external funds. While related papers explain their results only by numerical examples, we analytically prove the following results. In the presence of only a proportional cost of...

This paper investigates a principal-agent model in which an owner (principal) optimizes a contract with a manager (agent) delegated to undertake an investment project. In the model, we explore the effects of costly exploration by which the manager learns the real value of development cost. We...

We develop a real options model for evaluating and optimizing an R&D project. The model can capture key features of R&D, including research duration, growth opportunity, debt financing, and uncertainty of technological, demand market, and rival preemption. Nevertheless, it is computationally...

We develop a dynamic model in which a firm exercises an option to expand production on either a small or large scale with cash reserves and costly external funds. We show that the financing costs greatly distort the firmfs financing and investment behavior and result in a policy contingent on...
