This study pursues a dual objective: First, it evaluates the export
competitiveness of Türkiye’s hazelnut sector over the period 1970–2020
by employing the revealed symmetric comparative advantage index. Second,
it investigates the long-run and short-run dynamics between hazelnut
exports and a set of macroeconomic and sector-specific determinants,
including foreign direct investment, hazelnut export prices, hazelnut
production, real effective exchange rates, and terms of trade. To this
end, an autoregressive distributed lag bounds testing framework is
adopted, enabling the identification of both equilibrium relationships
and short-run adjustment mechanisms. The empirical findings confirm the
existence of a stable long-run relationship between hazelnut exports and
key economic fundamentals, accompanied by significant short-run
dynamics. However, foreign direct investment does not exhibit a robust
export-enhancing effect, suggesting that capital inflows into the sector
have not been effectively translated into increased hazelnut export
performance. The results underscore the dominant role of price
competitiveness and structural advantages in shaping Türkiye’s hazelnut
exports.
