Supporting Information Appendix S1: Technical Discussion When L < LB , the government knows that both sincere and opportunistic investors have incentives to make an investment. The updated belief that the investor is the sincere one, β, is thus equal to the prior belief, α. Expecting both types of investors to make an investment, the government enforces the labor laws if and only if L³ c E(D)(1 - a ) When L ³ LB , the government knows that the sincere type stops investing. So when the government observes investment made, it updates its belief that it is facing the sincere type, β = 0. In other words, the government is sure that it is facing the opportunistic type and enforces the labor laws if and only if c E(D) Note that c/E(D)(1-) is always greater than c/E(D)1 The equilibrium depends on how LB locates L³ in relation to c/E(D)(1-) and c/E(D). One possible case is LB < c/E(D) < c/E(D)(1-). When this is the case, the government does not enforce when L < LB and both the sincere and the opportunistic investors invest. When LB < L < c/E(D) , only the opportunistic investor invests, and the government decides not to enforce the labor laws. When c/E(D) < L, the government starts to enforce the labor laws, making the opportunistic investor discontinue its investment. This case is graphically illustrated in Figure 2(a). The x-axis denotes L. Another possible case is c/E(D) < c/E(D)(1-) < LB.2 When this is the case, the government starts to enforce the labor laws when L > c/E(D)(1-). Both types of investors continue to invest until L = LB. When L > LB, given that the government is willing to enforce the labor laws, both types of investors discontinue their investment. The discussion is succinctly captured in Figure 2(b). The equilibria are summarized in Table 2. 1 2 c c > 0. This is always the case given that c > 0, E(D) > 0, α < 1. E(D)(1 - a ) E(D) There is another case where LB sits between c/E(D) and c/E(D)(1-). This is a trivial case that does not yield any substantive insight, thus it is dropped from the discussion.
