I develop a dynamic quantitative framework, with heterogeneous firms and financial frictions, to study impact of corporate tax reforms directed at multinational firms. The model quantifies the impact of such reforms on productivity, GDP and welfare. Firms draw idiosyncratic productivity shocks, invest in capital and choose optimal financial structure. They choose endogenously whether to service the foreign market, through either exporting or FDI. I apply the framework to the removal of the U.S. repatriation tax as in the 2017 Tax Cuts and Jobs Act. The impact trades-off two selection effects --- offshoring from more U.S. multinationals versus greater entry that drives-out less productive firms. Comparing steady states, the tax reform brings higher productivity, GDP, welfare and approximate revenue neutrality. Dynamics are significant: along the transition, there are temporary welfare losses from short-term adverse labour market conditions. Financial frictions are also significant: their exclusion brings welfare losses when comparing steady states.

We develop and estimate a small open economy dynamic stochastic general equilibrium model to investigate the effectiveness of the Australian fiscal stimulus package introduced in the aftermath of the global financial crisis (GFC). The estimated model implies a fiscal multiplier of 0.9 on impact and 1.26 with one-year monetary accommodation. Utilising the estimated shocks – in particular, the fiscal shocks that mimic the stimulus transfers – we conduct several counterfactual policy experiments. Our results suggest that the stimulus transfers were almost equally important as the concurrent monetary easing actions in helping the Australian economy to avoid a recession after the GFC.
