Spectral utility,wiener-hopf techniques,and rational expectations

Purely classical, frequency-domain methods are useful for solving linear-quadratic dynamic rational expectations models. To illustrate this, generic scalar and multiple-variable problems are solved completely in the frequency domain. The procedure, which utilizes Wiener-Hopi methods to maximize the frequency-domain representation of the objective function, makes ordinarily troublesome second-order conditions transparent, allows infinite-order costs of adjustment, and handles moving average errors easily.     

Price-Fixing and Shareholder Returns: An Empirical Study

This paper examines the market reaction to three different events related to allegations of price-fixing: the initial charges, the firm's plea, and the resolution of the case. Negative, risk-adjusted shareholder returns are associated with the initial charge of price-fixing, while mixed results are observed during the two days immediately after the plea. The ultimate resolution of the case appears to be anticipated by the market. The overall decline in shareholder wealth from all three events combined is about 5 percent. These results suggest that shareholders are at least partial beneficiaries of price-fixing and that the presumption of an agency problem may be incorrect.

A note on “minimizing a weighted quadratic function of job lateness in the single machine system”

A set of jobs is to be scheduled on a single machine where an idle time is allowed to be inserted before the processing of the first job begins. The objective is to find an optimal sequence that minimizes the weighted sum of a quadratic function of job lateness. Sen et al. [Sen, T., Dileepan, P., Lind, M.R., 1995. Minimizing a weighted quadratic function of job lateness in the single machine system. International Journal of Production Economics 42(3), 237–243] presented a branch-and-bound algorithm for the problem; however, as shown in this note, their algorithm does not work because the branching rule for adjacent jobs is not applicable to non-adjacent jobs.
