CEP 1606 Specific Investment and Supplier Vulnerability Theory and Evidence
Apart from the familiar holdup problem, we investigate another implication of specific investment that has not been examined systematically in the literature. That is, the presence of specific investment can make a supplier vulnerable to large negative shocks to its customer's business. In a theoretical model, we demonstrate that this vulnerability causes the supplier to under invest. A higher degree of specificity induces the supplier to invest more, and it leads to a lower mean and higher volatility in the supplier's profit. Using panel data on over 5000 U.S. firms from 1990 to 2010, our empirical analysis shows the prevalence of the supplier vulnerability problem associated with specific investment.
