Demand Estimation with Text and Image Data
The RAND Journal of Economics, EarlyView.ABSTRACT We propose a demand estimation approach that leverages unstructured data to infer substitution patterns. Using pre‐trained deep learning models, we extract embeddings from product images and textual descriptions and incorporate them into a mixed logit demand model.

Assortative Mating and Female Labor Supply [PDF]
This paper investigates the pattern of wives' hours disaggregated by the husband's wage decile. In the US, this pattern has changed from downward-sloping to hump-shaped.

PLoS ONE, 2010 Assortative mating, a potentially efficient prezygotic reproductive barrier, may prevent loss of genetic potential by avoiding the production of unfit hybrids (i.e., because of hybrid infertility or hybrid breakdown) that occur at regions of secondary ...

adapt3: Adaptive dynamics and community projection in the R programming language
Methods in Ecology and Evolution, EarlyView.Abstract Ecologists typically use matrix projection to understand population dynamics. Recently, they have applied matrix projection to analyse communities and evolutionary dynamics. Particularly, matrix community models (MCMs) provide a reductionist, demographic approach to the study of ecological interactions, while adaptive dynamics assess the ...

Neighborhoods and Racial Inequality in Assortative Mating and Fertility in the United States
SocietiesWhile racial inequalities in assortative mating and fertility have been well documented, the role of neighborhoods has frequently been overlooked in explaining these disparities.

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys
Archaeometry, EarlyView.Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

Archaeometry, EarlyView.ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Evolution of assortative mating in a population expressing dominance.
PLoS ONE, 2011 In this article, we study the influence of dominance on the evolution of assortative mating. We perform a population-genetic analysis of a two-locus two-allele model.
