 Abstract

We measure foreign exchange exposures as sensitivity of firm’s value to FX premium in the CAPM plus FX premium model, and try to find determinants of the exposures; using data of non-financial companies listed in the Korea Exchange from the year 2007 to 2008. Main findings are as follows. If Korean won depreciates, only a small number of firms is benefitted while majority of firms are harmed to the contrary of common knowledge. As a firm’s export increases, the foreign exchange exposure increases up to a certain level and after that it declines. And, smaller firms of negative foreign exchange exposures are more sensitive to foreign exchange changes.Thesesuggestheterogeneouseffectsofforeignexchangerateson industries and firms.
