Expectations regarding the relationship between exchange rates and the prices of traded goOds in small open economies have traditionally been derived from the idea of the relative unimportance of a single small country when trading in much larger international markets. This concept has led to the use of distinct 'small-country' or 'dependent-economy' models to analyse the effects of macroeconomic changes. Thus for small economies like Australia, it is usually assumed that the foreign-currency prices of traded goods are fixed in perfectly competitive international markets. Accordingly, exchange rate movements must be completely absorbed in domestic-currency prices. In other words, the pass-through of exchange rate changes to destination-currency prices must be zero for Australian exports, and complete for Australian imports. Such expectations regarding the degree of exchange rate pass-through contrast sharply with those found in conventional macroeconomic models for large countries, in which pass-through is assumed to be complete for all traded goods. Moreover, they conflict with the results derived from the large theoretical and empirical literature on the microeconomic determinants of pass-through, which suggests that much international trade takes place in imperfectly competitive markets, in which the degree of less-than-complete pass-through depends on industry-specific factors. This study explores these apparent conflicts by re-examining the small-country assumption, with particular emphasis on export prices as the area of greatest divergence. Specifically, it addresses three research questions: 1) What are the theoretical conditions that underlie the small-country assumption? 2)What are the implications for the macroeconomic models of small economies if this assumption is violated? 3) In practice, is the data more consistent with the validity or otherwise of the assumption? The analysis focuses on Australia as a practical example of a small open economy with a high proportion of commodity exports. In summary, the theoretical and empirical results reported in this study suggest that the small-country assumption is unlikely to hold in practice. That is, exchange rate pass-through is more likely to be determined by industry-specific factors, rather than by the universal conclusion of zero pass-through for all Australian exports that is derived from the small-country assumption. Further, they imply that the movement in internal prices required to restore equilibrium in a small country following an external shock is likely to be both larger and more uncertain than has previously been expected. Under such circumstances, the full flexibility of the exchange rate, as the primary and most rapid source of the required adjustments, becomes particularly significant. An important policy implication for small open economies that are subject to frequent terms of trade shocks, such as Australia, is that attempts to manage the exchange rate in order to reduce apparently excessive movements may in fact result in a longer and more protracted process of adjustment through the labour market.
