Lasso-type and Heuristic Strategies in Model Selection and Forecasting

Savin, Ivan; Winker, Peter - Wirtschaftswissenschaftliche Fakultät, … - 2012

Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Emergence of Innovation Networks from R&D Cooperation with Endogenous Absorptive Capacity

Savin, Ivan; Egbetokun, Abiodun - Wirtschaftswissenschaftliche Fakultät, … - 2013

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with endogenous absorptive capacity. The networks emerge as a result of bilateral cooperation over time between firms occupying different locations in the knowledge space. Social...

Equilibrium Selection under Limited Control - An Experimental Study of the Network Hawk-Dove Game

Berninghaus, Siegfried; Schosser, Stephan; Vogt, Bodo - Wirtschaftswissenschaftliche Fakultät, … - 2013

For games of simultaneous action selection and network formation, game-theoretic behavior and experimental observations are not in line: While theory typically predicts inefficient outcomes for (anti-)coordination games, experiments show that subjects tend to play efficient (non Nash) strategy...

Psychology and Economics rather than Psychology versus Economics: Cultural differences but no barriers!

Brandstätter, Hermann; Güth, Werner; Kliemt, Hartmut - Wirtschaftswissenschaftliche Fakultät, … - 2009

During the last three decades the ascent of behavioral economics clearly helped to bring down artificial disciplinary boundaries between psychology and economics. Noting that behavioral economics seems still under the spell of the rational choice tradition - and, indirectly, of behaviorism - we...

Cooperation in a Risky Environment: Decisions from Experience in a Stochastic Social Dilemma

Artinger, Florian; Fleischhut, Nadine; Levati, M. Vittoria - Wirtschaftswissenschaftliche Fakultät, … - 2012

Often in cooperative situations, many aspects of the decision-making environment are uncertain. We investigate how cooperation is shaped by the way information about risk is presented (from description or from experience) and by differences in risky environments. Drawing on research from risky...

Availability of Information and Representation Effects in the Centipede Game

Crosetto, Paolo; Mantovani, Marco - Wirtschaftswissenschaftliche Fakultät, … - 2012

The paper presents the results of a novel experiment testing the effects of environment complexity on strategic behavior, using a centipede game. Behavior in the centipede game has been explained either by appealing to failures of backward induction or by calling for preferences that induce...

Inspecting the Poverty-Trap Mechanism - A Quantile Regression Approach

Krüger, Jens J. - Wirtschaftswissenschaftliche Fakultät, … - 2007

The issue of poverty traps is assessed using quantile regression. For that an augmentation of the usual convergence regressions by quadratic and cubic terms is used with emphasis on curve fitting rather than parameter estimation. The results show that the generic mechanism leading to poverty...

Tit for Others' Tat Repeated Prisoner's Dilemma Experiments with Third-Party Monitoring and Indirect Punishment

Bruttel, Lisa; Güth, Werner - Wirtschaftswissenschaftliche Fakultät, … - 2013

Two pairs of two participants each interact repeatedly in two structurally independent but informationally linked Prisoner's Dilemma games. Neither pair receives feedback about past choices by their own partner but is fully informed about the choices by the other pair. Considering this as a...

Alternating or compensating? An experimentrepeated sequential best shot game

Bruttel, Lisa; Güth, Werner - Wirtschaftswissenschaftliche Fakultät, … - 2013

In the two-person sequential best shot game, first player 1 contributes to a public good and then player 2 is informed about this choice before contributing. The payoff from the public good is the same for both players and depends only on the maximal contribution. Efficient voluntary cooperation...
