This chapter discusses tax policy in open economies. The chapter discusses the theory of optimum taxation in an economy open to international trade. Most formal models of optimum taxation assume away international trade. Its presence does not alter any basic issues or methods. The economic...

Brinkmanship is a “threat that leaves something to chance” – creating a risk of catastrophe that is high enough to deter the adversary but low enough to be acceptable to oneself. The Cuban missile crisis is offered as a classic example. We argue that in that crisis both sides lost control...

We re-examine the basic investment problem of deciding when to incur a sunk cost to obtain a stochastically fluctuating benefit. The optimal investment rule satisfies a trade-off between a larger versus a later net benefit; we show that this trade-off is closely analogous to the standard...

Evaluating Recipes for Development Success Avinash Dixit This article offers a provocative critique of the ability of research on the impact of institutions on growth to offer immediate and practical recommendations for reforming and redesigning institutions in developing countries and...

We develop continuous-time models of capacity choice when demand fluctuates stochastically, and the firm's opportunities to expand or contract are limited. Specifically consider costs of investing or disinvesting that vary with time, or with the amount of capacity already installed. The firm's...

We re-examine the basic investment problem of deciding when to incur a sunk cost to obtain a stochastically fluctuating benefit. The optimal investment rule satisfies a trade-off between a larger versus a later net benefit; we show that this trade-off is closely analogous to the standard...

Capital investment decisions must recognize the limitations on the firm's ability later to sell off or expand capacity. This paper shows how opportunities for future expansion or contraction can be valued as options, how this valuation relates to the q-theory of investment, and how these options...
