Applied Economic Perspectives and Policy, EarlyView.Abstract This paper employs machine learning to determine which preferential trade agreement (PTA) provisions are relevant to agricultural trade patterns and the factors that may influence their adoption. Utilizing the three‐way gravity model, we apply plug‐in Lasso regularized regression to pinpoint predictive PTA provisions for agricultural trade ...

Model-free Bootstrap for a General Class of Stationary Time Series [PDF]
arXiv, 2019 A model-free bootstrap procedure for a general class of stationary time series is introduced. The theoretical framework is established, showing asymptotic validity of bootstrap confidence intervals for many statistics of interest. In addition, asymptotic validity of one-step ahead bootstrap prediction intervals is also demonstrated.

MPBoot: fast phylogenetic maximum parsimony tree inference and bootstrap approximation
BMC Evolutionary Biology, 2018 The nonparametric bootstrap is widely used to measure the branch support of phylogenetic trees. However, bootstrapping is computationally expensive and remains a bottleneck in phylogenetic analyses. Recently, an ultrafast bootstrap approximation (UFBoot)

Exploring the relationship between growth in online shopping and multichannel food consumers
Applied Economic Perspectives and Policy, EarlyView.Abstract During the pandemic, many food retailers began offering online shopping options, primarily in reaction to rising consumer demand for such options, which was a response to supply chain disruptions and fear of contagion and food scarcity.

Comparison of Bootstrap Confidence Interval Methods for GSCA Using a Monte Carlo Simulation
Frontiers in Psychology, 2019 Generalized structured component analysis (GSCA) is a theoretically well-founded approach to component-based structural equation modeling (SEM). This approach utilizes the bootstrap method to estimate the confidence intervals of its parameter estimates ...

King and Cochrane: The technological treadmill and racial inequity in US agriculture
Applied Economic Perspectives and Policy, EarlyView.Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.
