Artifacts of Industry
Artifacts of Industry positions industrial plastic waste as an Anthropocene artifact that records humanity’s impact on the environment. My multimedia sculptures begin with casts of factory scraps—evidence of processes that occurred in other places and time periods. Working with the forms of these industrial remnants, I contemplate their pasts and their histories, and I imagine the experiences that imbue and shape each object. In transforming these artifacts, I aid their transition, rebirthing them into a new phase of existence
R2 Bounds for Predictive Models: What Univariate Properties Tell us About Multivariate Predictability
A long-standing puzzle in macroeconomic forecasting has been that a wide variety of multivariate models have struggled to out-predict univariate models consistently. We seek an explanation for this puzzle in terms of population properties. We derive bounds for the predictive R2 of the true, but unknown, multivariate model from univariate ARMA parameters alone. These bounds can be quite tight, implying little forecasting gain even if we knew the true multivariate model. We illustrate using CPI inflation data
