We introduce distributive justice into a simple model of growth and distribution. Two groups (‘classes’) of otherwise identical, capital-rich and capital-poor individuals (‘capitalists’) and (‘workers’) are in conflict over factor (labour-capital) shares. Capitalists’ (workers’)...

We examine how structural reforms relate to income inequality. We employ many indicators of structural reforms and use data for market and net income inequality. The dataset includes up to 135 countries since 1960. The results do not suggest that market-oriented structural reforms were...

In response to the Covid-19 pandemic, governments around the world have provided a massive fiscal and monetary stimulus. While this policy is welcome in the short run, it does not address the underlying problem in the medium and long run. The reason is that the pandemic has not given rise to a...

We find an economic rationale for the common sense answer to the question in our title - courts should not always enforce what the contracting parties write.We describe and analyze a contractual environment that allows a role for an active court. An active court can improve on the outcome that...

Electricity transmission redistributes environmental impacts across space. We exploit episodes of high electricity transmission system congestion to explore changes in ambient concentrations of air pollutants in the eastern United States. Reducing electricity system congestion decreases ozone...

We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road’s throughput). We show that the external cost – even when roads are not hypercongested...

This paper studies the implications of monopsony power for optimal income taxation and welfare. Firms observe workers’ abilities while the government does not and monopsony power determines what share of the labor market surplus is translated into profits. Monopsony power increases the tax...

Using new data on linguistic diversity across and within countries, we examine novel channels though which language affects trade patterns and economic welfare. We find that linguistic similarity within a country accounts for about 10 percent of estimated ‘home bias’, demonstrating the...

This paper reexamines the design of the optimal lockdown strategy by paying attention to its robustness to the postulated social welfare criterion. We first characterize optimal lockdown under utilitarianism, and we show that this social criterion can, under some conditions, imply a COVID19...

Decisions concerning marriage, fertility, participation, and the education of children are explained using a two-stage game-theoretical model. The paper examines the effects of (i) family law (cost of obtaining a divorce, alimony, availability of quasi-marriages such as PACS in France, and civil...
