Thomas Piketty's monumental Capital in the Twenty-First Century has transported us to a higher understanding of historical movements in inequality. This essay ranks the promise of different paths that scholars can usefully follow from the point to which his book has guided us. The main path to...

Private ownership should generally be preferred to public ownership when the incentives to innovate and to contain costs must be strong. In essence, this is the case for capitalism over socialism, explaining the dynamic vitality' of free enterprise. The great economists of the 1930s and 1940s...

How important is human capital at the top of the U.S. income distribution? A primary source of top income is private "pass-through" business profit, which can include entrepreneurial labor income for tax reasons. This paper asks whether top pass-through profit mostly reflects human capital,...

This chapter reviews the recent debate about the role of social capital in economics. We argue that all the difficulties this concept has encountered in economics are due to a vague and excessively broad definition. For this reason, we restrict social capital to the set of values and beliefs...

We develop a model in which the capital of the intermediary sector plays a critical role in determining asset prices. The model is cast within a dynamic general equilibrium economy, and the role for intermediation is derived endogenously based on optimal contracting considerations. Low...

We study the joint dynamics of economic and political change. Predictions of the simple model that we formulate in the paper get considerable support in a panel of data on political regimes and GDP per capita for about 150 countries over 150 years. Democratic capital -- measured by a nation's...

Firms spend substantial resources on marketing and selling. Interpreting this as evidence of frictions in product markets, which require firms to spend resources on customer acquisition, this paper develops a search theoretic model of firm dynamics in frictional product markets. Introducing...
