Why would anyone want to use antitrust law as a wealth distribution device when far more explicit statutory tools are available for that purpose? One feature of antitrust is its open-textured, nonspecific statutes that are interpreted by judges. As a result, using antitrust to redistribute...

What determines wealth inequality and mobility and how can the policy maker influence it? This paper quantifies in closed form the bottom and the top (Pareto) tail of the distribution in a continuous-time heterogeneous agent model. Financial market imperfections play a key role, for which...

While in the data wealth is concentrated in the hands of a small number of rich people and the saving rate of the rich is high, many models used for quantitative policy evaluation fail to match these facts. In addition, some of the models that succeed in matching these facts have radically...

Macroprudential policies, such as caps on loan-to-value (LTV) ratios, have become part of the policy paradigm in emerging markets and advanced countries alike. Given that housing is the most important asset in household portfolios, relaxing or tightening access to mortgages may affect the...

We describe a simple method to obtain kindred stationary densities of random Markov processes with respect to an Ito transformation function. As applied to income and wealth densities, they are akin to one another because they share the income growth and income volatility shape parameters. The...

Our computational economic analysis investigates the relationship between inequality and the financial accumulation process in the study of income and wealth distributions. Extending the baseline model by Levy et al., we characterise the economic process trough featured return structures...
