Abstract

The causes of food price spikes are complex, and their impact on different countries varies depending on production levels and the varied policies in place. Countries in Central Asia and the Caucasus (CAC) region have implemented a wide range of reforms that vary in form and speed. The existing scientific literature reports about the consequences of price spikes in CAC; however, to date, a comparison of impact between those countries has not been made in terms of the entire supply chain perspective. Therefore, this study investigates the impact of the price spikes on the entire wheat supply chain for the first time in CAC and discusses the role of policies. Another contribution of this study is an evidence-based analysis of the role of policy reformation in maintaining food security under price shocks. Our results indicate a very limited effect of price interventions and trade restrictions on dampening wheat prices in all countries. We find that only trade diversification policy had a positive effect on reducing the level of price spikes, and thus it might be a suitable policy measure for maintaining food security.

价格飙升对各国和供应链参与者的异质性影响:来自中亚和高加索地区的证据。回顾

粮食价格飙升的原因是复杂的，其对不同国家的影响因生产水平和不同的政策而异。中亚和高加索地区的国家实施了形式和速度各异的广泛改革。现有的科学文献报道了CAC价格飙升的后果;然而，迄今为止，还没有从整个供应链的角度对这些国家之间的影响进行比较。因此，本研究首次在CAC中考察了价格飙升对整个小麦供应链的影响，并讨论了政策的作用。本研究的另一个贡献是基于证据分析了政策改革在价格冲击下维持粮食安全方面的作用。我们的研究结果表明，在所有国家，价格干预和贸易限制对抑制小麦价格的影响都非常有限。研究发现，只有贸易多样化政策对降低价格上涨水平具有积极作用，因此贸易多样化政策可能是维持粮食安全的合适政策措施。
