This paper presents estimates of the effects that terms of trade volatility has on growth of real gross domestic product per capita. Based on five-year non-overlapping panel data comprising 175 countries during 1980-2010, the paper finds that: (i) in model specifications that do not include country fixed effects, terms of trade volatility has a significant negative average effect on economic growth
(ii) once country fixed effects are included in the model, the average effect of terms of trade volatility on economic growth is not significantly different from zero
(iii) robust to the inclusion of country fixed effects, terms of trade volatility has significantly adverse effects on economic growth in countries with pro-cyclical fiscal policy
and (iv) in model specifications that do not include country fixed effects, financial development is a significant mediating factor with regard to the effect that terms of trade volatility has on economic growth, however, the significance of this effect vanishes once country fixed effects are included in the model. The paper also explores these relationships for the Organization of Eastern Caribbean States region. A key conclusion from the research is that countercyclical fiscal policy and deeper financial markets will have particularly high payoffs in reducing the adverse growth effects of terms of trade volatility in the Organization of Eastern Caribbean States region.
