A decision maker tests whether the gradient of the loss function evaluated at a judgmental decision is zero. If the test does not reject, the action is the judgmental decision. If the test rejects, the action sets the gradient equal to the boundary of the rejection region. This statistical...

Bayesian decisions are observationally identical to decisions with judgment. Decisions with judgment test whether a judgmental decision is optimal and, in case of rejection, move to the closest boundary of the confidence interval, for a given confidence level. The resulting decisions condition...

This paper provides a survey of simulation in supply chain management. It reviews four types of simulation, namely spreadsheet simulation, system dynamics, discrete event simulation, and business games. Which simulation type should be applied, depends on the type of managerial question to be...

Periods of economic and financial stress traditionally give rise to profound changes in economic theory and in the way policy decisions are taken. Motivated by the recent interest in renewing macroeconomics after the global financial crisis, we collected the views of senior central bank staff in...

We consider an artificial population of forward looking heterogeneous agents making decisions between schooling, employment, employment with training and household production, according to a behavioral model calibrated to a large set of stylized facts. Some of these agents are subject to policy...

The popular impression that Africa has not integrated into world trade, as suggested by the evolution in simple indicators, has been called into question recently by more formal analysis. This paper refines and generalizes this analysis and lends support to the popular view of disintegration,...

The problem of forecasting the economic systems' activity over a large time horizon is the main concern of both the researchers in the economic field and the system managers. In most cases, its solving is reduced to simulating the structure of the economic indicators which render the system...

Investment in infrastructure such as the information and communication technology sector requires large, substantial amounts, most of which are sunk or irreversible. Uncertainty of market demand, competition, costs and public policy complicates the investment decision process. This paper...
