This paper describes the design and implementation in MPI of the parallel vector library CVL, which is used as the basis for implementing nested data-parallel languages such as NESL and Proteus. We outline the features of CVL, and compare the ease of writing and debugging the portable MPI implementation with our experiences writing previous versions in CM-2 Paris, CM-5 CMMD, and PVM 3.0. We giv...

This survey discusses behavioral and experimental macroeconomics, emphasizing a complex systems perspective. The economy consists of boundedly rational heterogeneous agents who do not fully understand their environment use simple decision heuristics. Central to our is the question under which conditions macro-system interacting may or coordinate on equilibrium outcome. A general finding that po...

This paper shows that if a very small, exogenously given probability of terminating the exchange is introduced in an elementary investment game, more reciprocators will choose the defection strategy. Everything happens as if they "hide behind probabilities" in order to break the trust relationship. Investors do not alter their behavior in a significant way, at least not for a very small externa...

In this paper we investigate experimentally the effects of a wage tax financed unemployment benefit system on the development of the budget deficit, unemployment, and some other indicators of economic performance in an international economy. We find support for the hypothesis that out-of-equilibrium price uncertainty affects the behavior of economic agents. Due to uncertainty about prices risk-...

An experiment is a structured model to measure the validity of a hypothesis. There is extensive literature on how to design an experiment, derived by taking a already run experiment as a starting point, and determining what could be done better to get results that are more conclusive. As a result, the concept of an experiment has been treated informally, but if we seek to design an experiment, ...

The formation of human capital is important for a society's welfare and economic success. Recent literature shows that child health can provide an important explanation for disparities in children’s human capital development across different socio-economic groups. While this literature focuses on cognitive skills as determinants of human capital, it neglects non-cognitive skills. We analyze dat...

Bertrand competition under decreasing returns involves a wide interval of pure strategy Nash equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. More firms lead to lower average prices. However, prices remain substantially above the Walrasian level. With more than two firms the predominant market price...

Who Is Coming to the Artefactual Field Experiment? Participation Bias among Chinese Rural Migrants In this paper, we compare participants in an artefactual field experiment in urban China with the survey population of migrants from which they were recruited. The experimental participants were more educated, more likely to lend money to friends, and worked fewer hours than the general population...

Lobbying is studied in a series of signaling game experiments. Students as well as professional lobbyists are used as subjects. In contrast with some earlier studies, comparing students and professionals, we find significant differences in the behavior of the two subject pools. Professional subjects appear to behave more in line with the game–theoretic predictions, display a higher degree of se...

Previous studies have shown that decision makers are less other-regarding when their own payoff is risky than when it is sure. Empirical observations also indicate that people care more about identifiable than unidentifiable others. In this paper, we report on an experiment designed to explore whether rendering the other identifiable − via a short speechless video − can affect the relation betw...
