Trade and War, Reconsidered [Non-Technical Summary]

A study re-examining the relationship between international trade and military conflicts, focusing on differences in state regimes.

Key Points

1. Research Background and Motivation

  • Military conflicts persist globally, including Russia's 2022 invasion of Ukraine and the 2023 Hamas-Israel conflict
  • Interstate military conflicts have not decreased since World War II
  • While global imports have rapidly increased, especially since the 2000s, conflicts continue
  • Russia invaded Ukraine despite Ukraine being its 16th most important trading partner

2. New Research Perspective

  • Incorporates differences in state regimes (democracies, authoritarian states, hybrid states) into the analysis
  • In democracies, businesses and citizens can influence government through voting
  • In authoritarian states, rulers may take military action without considering negative impacts on citizens
  • Re-examines the relationship between trade and peace since Montesquieu's "The Spirit of Laws" in the 18th century

3. Methodology and Data

  • Uses interstate military conflict data from 1976-2014
  • Quantitative estimation analysis combining bilateral trade data and state regime data
  • Utilizes reliable data sources including Correlates of War database and UN Comtrade

4. Key Research Findings

  • Increased bilateral trade is associated with reduced conflict probability
  • This relationship is particularly pronounced among democratic state pairs
  • No trade-conflict deterrence relationship found among authoritarian state pairs
  • State regime combinations have a decisive impact on trade's conflict deterrent effect

The article concludes that the conflict-deterring effect of international trade heavily depends on state regimes, being effective between democracies but limited between authoritarian states.
