We study the optimal progressivity of income taxation in a Bewley-Grossman model of health capital accumulation where individuals are exposed to earnings and health risks over the lifecycle. We impose the U.S. tax and transfer system and calibrate the model to match U.S. data. We then optimize...

We quantify the effects of population aging on the U.S. healthcare system. Our analysis is based on a stochastic general equilibrium overlapping generations model of endogenous health accumulation calibrated to match pre-2010 U.S. data. We find that population aging not only leads to large...

We study the progressivity of Australia's personal income tax system after the introduction of a New Tax System (Goods and Services Tax) Act 1999. We use two data sets: administrative data from Australian Tax Office (ATO) 2004-16 and survey data from the Household Income and Labour Dynamics in...

In this study, we quantify the macroeconomic and welfare effects of alternative fiscal consolidation plans in the context of a small open economy. Using a computable overlapping generations model tailored to the Australian economy, we examine immediate and gradual eliminations of the existing...

In this paper we quantitatively explore the overall welfare bene ts of social health insur-ance which is embedded in the US mixed health insurance system. We compare the currentUS mixed insurance system to three alternative systems: (i) a no health insurance system,(ii) a purely private health...

We formulate an overlapping generations model with skill heterogeneity and productive and non-productive government programs to study the macroeconomic and intergenerational welfare effects caused by risk premium shocks and government debt reductions. We demonstrate that in a small open economy...

We study optimal income tax progressivity in an environment where individuals are exposed to idiosyncratic income and health risks over the lifecycle. Our results, based on a calibration for the US economy, indicate that the presence of health risk combined with incomplete insurance markets...

In Brazil, generous public sector pensions have induced civil servants to retire on average at age 55. In this paper we use an OLG model to assess the effects of such policy induced early retirement on capital accumulation and long-run income levels. We calibrate the model to data from Brazil...

We investigate the dynamic general equilibrium effects of introducing a social assistance program to elderly informal sector workers in developing countries. We find that the extension of such ldquo;retirement benefitsrdquo; in environments with lacking private sector risk-sharing mechanisms...

We use an OLG model to study the effects of the generous public sector pension system in Brazil. In our model there are two types of workers, one working in the private sector, the other working in the public sector. Public workers produce infrastructure or education services. We find that...
