We ask how pension fund trustees deal with the booms and busts that funds encounter, and to what extent the decisions of pension fund trustees are affected by behavioral biases. We examine these issues by using a vignette-method field experiment among Dutch pension fund trustees. We find that...

Abstract: Using a survey dataset of Chinese rural households, we find that access to external finance is positively … associated with the decision to become entrepreneur, the initial investment for microenterprises and the use of external finance …. Also, we find that the use of informal finance is positively associated with sales growth of microenterprises with …

In this paper we investigate global optimization for black-box simulations using metamodels to guide this optimization. As a novel metamodel we introduce intrinsic Kriging, for either deterministic or random simulation. For deterministic simulation we study the famous `efficient global...

In practice, simulation analysts often change only one factor at a time, and use graphical analysis of the resulting Input/Output (I/O) data. Statistical theory proves that more information is obtained when applying Design Of Experiments (DOE) and linear regression analysis. Unfortunately,...

Abstract: This chapter first summarizes Response Surface Methodology (RSM), which started with Box and Wilson’s article in 1951 on RSM for real, non-simulated systems. RSM is a stepwise heuristic that uses first-order polynomials to approximate the response surface locally. An estimated...

This contribution presents an overview of sensitivity analysis of simulation models, including the estimation of gradients. It covers classic designs and their corresponding (meta)models; namely, resolution-III designs including fractional-factorial two-level designs for first-order polynomial...

This article is the first attempt to study the empirical link between income aspirations and cooperation in a one shot public good game. By combining experimental with survey data, we find evidence that the more frustrated people are with their income, the lower is their propensity to cooperate...

This article uses a sequentialized experimental design to select simulation input com- binations for global optimization, based on Kriging (also called Gaussian process or spatial correlation modeling); this Kriging is used to analyze the input/output data of the simulation model (computer...

We study an experimental market in which the structure of the information flows is endogenized. When making an offer, traders choose not only the price at which they are prepared to trade, but also the subset of traders they want to inform about the offer. This design allows for two extreme...
