Behavioral and Experimental Economics

Summer School Experimental Economics

The Behavioral and Experimental Economics group has an influential position in this field in the Netherlands and Europe. CREED, the Amsterdam-based group, focuses particularly on three main projects: economics of political decision making; bounded rationality and institutions and experimental economics. The research of the Rotterdam-based group focuses on two broad themes: decision under risk and uncertainty and intertemporal choice.

Cooperative Behavior, Strategic Interaction and Complex Systems

This research group focuses on: (non-)cooperative game theory; nonlinear dynamics and complex systems; bounded rationality, learning and heterogenous expectations; dynamic models of collective behavior and social networks & dynamic optimization.

Econometrics and Operations Research

Research themes: time series econometrics, panel data, Bayesian econometrics, applied econometrics and econometric methodology. Applications can be found in areas as diverse as monetary economics, labor economics, marketing and asset pricing. Some fellows in this group focus on operations research.

Finance

The Finance group at TI spans many of the core fields in finance: asset pricing, corporate finance, financial econometrics, market microstructure, and financial institutions.

Labor, Health, Education and Development

At TI, a large group of fellows works in different areas of labour, health, education and development.

Macroeconomics and International Economics

Fellows in the Macroeconomics and International Economics group carry out research on growth, innovation, international trade and factor mobility, the role of economic geography, banking and monetary economics, and fiscal policy.

Organizations and Markets

The Organizations and Markets (OM) group spans many areas in (applied) microeconomics, including the economics of organizations, industrial organization, entrepreneurship, innovation, and auctions.

Spatial, Transport and Environmental Economics

The STEE group addresses four themes: urban and regional dynamics, land use, transportation, and environment and resources. Many fellows combine policy research with fundamental research.

This paper introduces a parameter-free method for measuring the weighting functions of prospect theory and rank-dependent utility. These weighting functions capture risk attitudes, subjective beliefs, and ambiguity attitudes. Our method, called the midweight method, is based on a convenient way to obtain midpoints in the weighting function scale. It can be used both for risk (known probabilities) and for uncertainty (unknown probabilities). The resulting integrated treatment of risk and uncertainty is particularly useful for measuring ambiguity, i.e., the difference between uncertainty and risk. Compared to existing methods to measure weighting functions and attitudes toward uncertainty and ambiguity, our method is more efficient and can accommodate violations of expected utility under risk. An experiment demonstrates the tractability of our method, yielding plausible results such as ambiguity aversion for moderate and high likelihoods but ambiguity seeking for low likelihoods, as predicted by Ellsberg.
