12.3 Probability of Success of Economic Sanctions

Before conducting a quantitative analysis of the trade war, let us first study the probability of success of trade wars throughout history.

The results of economic sanctions can be divided into three types:

Success, failure, and uncertainty. Generally, both sides claim victory after economic sanctions. What is success and failure? No extremely precise definition is offered academically. In fact, even the definition of trade war offers a broad space for explanation. In some conflicts between countries, only one side threatens to use economic sanctions but threatens nothing more. Is this situation considered a trade war?

Therefore, the big difference in the statistical data in research liter- ature on trade wars is understandable.

The bottom-line definition of a successful trade war is the achieve- ment of the goal. All the same, discussing the cost spent is necessary. If the country spends much and even loses more rather than gain, it fails even if it achieves the goal. If the country achieves the goal by other means, such as sending troops or solving the problem after a long time (e.g., the other side changes government), it does not succeed in the real sense. Economic sanctions are often combined with other political and military means in conflicts between countries. Therefore, accurately evaluating the effect of economic sanctions is difficult.

The failure of economic sanctions is relatively easy to determine.

Events do not happen as planned, and economic sanctions do not work. The results of most economic sanctions are not evident. Attack- ers usually talk a great deal with minimal follow-up action, which should be defined as failure.

Hufbaver et al. invested much effort in quantitatively analyzing the cost and benefit of economic sanctions. These researchers roughly divided the results of economic sanctions into two categories: success for those achieving the goal and failure for those not achieving the goal or not having definite results.6 Although their method of divi- sion deserves elaboration and improvement, no situation seems to be better than the present.

According to Table 12.2, the probability of success of economic sanctions before the Second World War is 43.8%. After the war, economic sanctions occurred more frequently, with the probability of success at 35%.

The U.S. noticeably not only joins in the economic sanctions it leads but also imposes them alone. Before the Second World War, almost all economic sanctions independently imposed by the U.S. had no results. In 1945 and 1969, relative to other countries, the U.S. had prominent economic and military advantages. Thus, the probability of success of economic sanctions solely led by the U.S. was as high as 62.5%. Afterwards, the diverse world pattern caused the American hegemony to gradually decline. Thus, the probability of success of economic sanctions led by the U.S. declined to 19.5%. In 1990 and 2000, the success probability further decreased to 18.2%.

G. Haufbaver and his colleagues summarized more than 200 eco- nomic sanctions since. Their research reveals that the probability of success of different sanction methods is 17.9% by only restricting the export, 20% by restricting only the import, 25% by restricting both import and export, and 40.3% by combining the financial sanctions as well as import and export sanctions. Clearly, if the standard of the successful economic sanctions increases, the probability of success for economic sanctions will be much lower than that of the above research. For instance, Robert Pape in the University of Chicago holds that the probability of success of economic sanctions is only 5%

(Table 12.3).

As previously mentioned, if the U.S. launches a trade war against China, the former will neither adopt financial sanctions nor further restrict exports. If the U.S. restricts the import of Chinese goods separately, the probability of success will be the lowest in history.

In fact, as long as the U.S. restricts the import of goods made in

China, the latter will retaliate and take countermeasures at once to restrict the import of U.S. goods. If the market is small in China, the U.S. will not feel the impact of losing the Chinese market, thus launching a trade war can be done at low cost and a high probability of success can be achieved. If the market is very large in China, the U.S. economy will be seriously affected if it loses the Chinese market.

Thus, the U.S. should think carefully if provoking a trade war against China is worthwhile.
