Assessing the Exchange Rate Sensitivity of U.S. Bilateral Agricultural Trade

This paper uses an autoregressive distributed lag approach to cointegration to examine the short- and long-run effects of exchange rate changes on bilateral trade of agricultural products between the United States and its 10 major trading partners. Results show that, in the long run, while U.S. agricultural exports are highly sensitive to bilateral exchange rates and foreign income, U.S. agricultural imports are mostly responsive to the U.S. domestic income. In the short run, on the other hand, both the bilateral exchange rates and income in the United States and its trading partners are found to have significant impacts on U.S. agricultural exports and imports.
Dans le présent article, nous avons utilisé un modèle autorégressif à retards échelonnés (autoregressive distributed lag (ARDL) approach to cointegration) pour examiner les effets à court et à long terme des variations de taux de change sur le commerce bilatéral des produits agricoles entre les États-Unis et ses dix principaux partenaires commerciaux. Les résultats ont montré que, à long terme, bien que les exportations agricoles des États-Unis soient très sensibles aux taux de change bilatéraux et au revenu étranger, les importations agricoles des États-Unis sont principalement sensibles au revenu intérieur des États-Unis. À court terme, par contre, les taux de change bilatéraux et le revenu des États-Unis et de ses partenaires commerciaux ont des répercussions considérables sur les exportations et les importations agricoles des États-Unis.     

The Korea-Vietnam trade and the bilateral exchange rate: Asymmetric evidence from commodity trade data

The contribution of the current article is to detect the asymmetric impact that exchange rate fluctuations have on Korea's trade with Vietnam. To this end, the nonlinear autoregressive distributed lag (NARDL) process is applied to export and import data disaggregated by 25 commodities. We uncover that the ups and downs of exchange rates have an asymmetric impact on some, though not all, types of Korea's commodities exported to and imported from Vietnam in both the long- and short-run.     

Linkages between natural gas,fertiliser and cereal prices: A note

We use structural vector autoregressions to analyse the dynamic effects of shocks to natural gas and nitrogenous fertiliser prices on three major cereal crops: maize, rice and wheat. We find that the response of cereal prices to natural gas and fertiliser price shocks has been relatively small, instantaneous and transitory. These findings suggest that crop prices may change rapidly in response to energy and fertiliser prices, even when there are no shifts in the underlying fundamentals in crop markets. Furthermore, because the effects of the shocks dissipate rather quickly, short-term measures to address swings in food prices may suffice.
