Tariffs and privatization policy in a bilateral trade with corporate social responsibility

Corporate social responsibility (CSR) has become a global business strategy and thus it provides significant welfare implications for designing optimal policies. This paper investigates the impact of CSR on policy interaction between tariffs and privatization in an international bilateral trade model. We find that CSR is closely related to the government's policy decisions on tariffs. In particular, we find that the strategic tariff for increasing domestic welfare is always higher (lower) than the efficient tariff for improving global welfare when the degree of CSR is low (high). We also show that a privatization policy raises tariff and worsens (improves) domestic welfare when the degree of CSR is low (high). Finally, we demonstrate that both countries choose a nationalization policy even though the privatization policy is globally optimal when the degree of CSR is high.
