Modeling Macroeconomies as Open-Ended Dynamic Systems of Interacting Agents Blake LeBaron and Leigh Tesfatsion, AER Papers & Proceedings, 98(2), 246-250 “All models are wrong, but some are useful.” G.E.P. Box (1979, p. 202) Macroeconomists seek to understand the structure and performance of economies at a national or regional level and the manner in which government policy makers attempt to inf...

The comparison of physical ages of geological materials measured by laboratories engaged in geochronological studies has been limited by the accuracy of mineral standards or monitors for which reported ages have differed by as much as 2 %. In order to address this problem, the U.S. Geological Survey is planning to calibrate the conventional (40)Ar/(40)K age of a new preparation of an internatio...

Evolutionary developmental biology is based on the principle that evolution arises from hereditable changes in development. Most of this new work has centred on changes in the regulatory components of the genome. However, recent studies (many of them documented in this volume) have shown that development also includes interactions between the organism and its environment. One area of interest c...

This thesis focuses on gaining linguistic insights into textual discussions on a word level. It was of special interest to distinguish messages that constructively contribute to a discussion from those that are detrimental to them. Thereby, we wanted to determine whether “I”and “You”-messages are indicators for either of the two discussion styles. These messages are nowadays often used in guide...

Grade II gliomas are slowly growing primary brain tumors that affect mostly young patients. Cytotoxic therapies (radiotherapy and/or chemotherapy) are used initially only for patients having a bad prognosis. These therapies are planned following the "maximum dose in minimum time" principle, i. e. the same schedule used for high-grade brain tumors in spite of their very different behavior. These...

Martin Eichenbaum is a professor of economics at Northwestern University and a senior consultant to the Federal Reserve Bank of Chicago. In this article, I offer some comments on the role of econometrics in macroeconomics. 1 These reflect a specific perspective: The role of econometrics ought to be the advancement of empirically plausible economic theory. This is a natural perspective for any e...

Cogeneration power plants simultaneously generate power and usable heat in a single, integrated system, which achieves a degree of overall efficiency that is much greater compared to electricity production alone. This makes better use of energy conversion and reduces greenhouse gas emissions. Combined heat and power production is already relatively common in Europe while it is less common, for ...

This paper introduces discrete large games where the set of players is a countable dense ‘grid’ with a finitely additive distribution. In these games any function from player names to mixed actions is a legitimate strategy profile. No extraneous continuity or measurability conditions are assumed. Randomness can be modeled explicitly and an exact law of large numbers holds. Equilibria enjoy a st...

The Taiwan Biobank (TWB) is a biomedical research database of biopsy data from 200 000 participants. Access to this database has been granted to research communities taking part in the development of precision medicines; however, this has raised issues surrounding TWB's access to electronic medical records (EMRs). The Personal Data Protection Act of Taiwan restricts access to EMRs for purposes ...

We appreciate the thoughtful comments by Subramanian and O’Malley to our paper on comparing mixed models and population average models, and the opportunity this response affords us to make a stronger and more general case regarding prevalent misconceptions surrounding statistical estimation. There are several technical points made in the paper that can be debated, but we will focus on what we b...
