The simulation result of Nunes, Kuan, and Newbold suggests that it is possible to estimate a spurious break for a regression model with I(1) disturbances. In this note, we provide a rigorous proof for this phenomenon.

The standard version of "q" theory, in which investment is positively related to marginal "q", breaks down in the presence of fixed costs of adjustment. With fixed costs, q is a non-monotonic function of investment. Therefore its inverse, which is the traditional investment function, does not...

I illustrate the convergence to Rubinstein's (1982) bargaining outcome of the solutions of the finite-horizon truncations of that game. The depiction is new, and hopefully instructive, and has the flavour of international trade diagrams.

This paper studies properties of stochastic objective functions, that is, objective functions which can be written as the expected value of a payoff function.
