The success of metaheuristics on hard single-objective optimization problems is well recognized today. Many real-life problems require, however, taking into account several conflicting points of view corresponding to multiple objectives. The use of metaheuristic optimization techniques for...

In this paper, we introduce a new Bayesian approach to explain some market anomalies during financial crises and subsequent recovery. We assume that the earnings shock of an asset follows a random walk model with and without drift to incorporate the impact of financial crises. We further assume...

Diagnostic expectations have emerged as an important departure from rational expectations in macroeconomics and finance. We present a first treatment of diagnostic expectations in linear macroeconomic models. To this end, we establish a strong additivity property for diagnostic expectations. The...
