Can urban coffee consumption help predict U.S. inflation? (2019)
Journal Article

Motivated by the importance of coffee to Americans and the significance of the coffee subsector to the US economy, we pursue three notable innovations. First, we augment the traditional Phillips curve model with the coffee price as a predictor, and s... Read More

Improving the predictability of the oil–US stock nexus: The role of macroeconomic variables (2019)
Journal Article
Salisu, A. A., Swaray, R., & Oloko, T. F. (2019). Improving the predictability of the oil–US stock nexus: The role of macroeconomic variables. Economic modelling, 76, 153-171. https://doi.org/10.1016/j.econmod.2018.07.029

In this study, we revisit the oil–stock nexus by accounting for the role of macroeconomic variables and testing their in-sample and out-of-sample predictive powers. We follow the approaches of Lewellen (2004) and Westerlund and Narayan (2015), which... Read More

A firm-level analysis of the upstream-downstream dichotomy in the oil-stock nexus (2018)
Journal Article
Swaray, R., & Salisu, A. A. (2018). A firm-level analysis of the upstream-downstream dichotomy in the oil-stock nexus. Global finance journal, 37, 199-218. doi:10.1016/j.gfj.2018.05.007

In this paper, we query whether the stock prices of nonintegrated firms in the upstream and downstream sectors of the global oil supply chain respond symmetrically to changes in oil prices. This inquiry relates to the “homogenous expectation” assumpt... Read More

U.S. stocks in the presence of oil price risk: Large cap vs. small cap (2017)
Journal Article
Swaray, R., Salisu, A. A., & Oloko, T. (2017). U.S. stocks in the presence of oil price risk: Large cap vs. small cap. Economics and business letters, 6(4), 116-124. https://doi.org/10.17811/ebl.6.4.2017.116-124

This study queries the act of making generalization about the dynamics of returns and volatility spillovers between oil price and U.S. stocks by merely considering only large cap stocks. It argues that this kind of generalization may be misleading, a... Read More
