Are Soybean Yields Getting a Free Ride from Climate Change? Evidence from Argentine Time Series Data

We analyze the influence of climate change on soybean yields in a multivariate time-series framework for major producer and exporter—Argentina. Long-run relationships are found partial systems involving climatic, technological, economic factors. Automatic model selection simplifies dynamic specification permits encompassing tests different hypotheses. Soybean adjust to disequilibria that reflect technological improvements seed crops practices. Climatic effects include (a) positive effect from increased CO2 concentrations, which may capture accelerated photosynthesis, (b) negative high local temperatures, could increase with continued global warming.
