The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global response of the employment rate, which depends not only on the participation (labor supply) responses, but also on the vacancy posting (labor demand) responses and on the product of these two types of responses. For plausible parameters, our matching environment induces much lower employment tax rates than the usual competitive participation model.
