It is also said that because of the disruption even U.S. automobile production was scaled down, since most makers source parts and components from Japanese suppliers. This implies how important, or unique, Japanese parts are for auto makers in the U.S., or raises a question of why those makers within the U.S. were not simply able to change suppliers.\n 　This study investigates the question using an incomplete contract model, in which the situation can be seen as a hold-up problem. A maker contracts out production of a specific part with a particular supplier, but because of the technological importance it has to rely on the supplier. To investigate, I estimate and compare the degree of the import elasticity of substitution between countries for parts to the U.S. With the Armington’s assumption, a regression model derived from the two-level constant-elasticity-of-substitution (CES) production function, augmented by a rule of law index, is estimated. It is shown that a part category such as integrated circuits, including micro-controller units, in fact has relatively lower degree of the elasticity of substitution than other parts. Therefore, it might be inferred that regardless of whether firms belong to a vertical production network, it is technologically necessary to procure some parts from Japanese part suppliers.
