In this paper, I present a theory of dynamic economic growth, business cycles, and asset pricing that integrates (1) Marx's idea (and emphasized by Klein) of a two-class heterogeneity of the ownership structure of physical capital and human capital in a capitalist society, (2) Keynes' idea of...

Distortions in private investment due to credit frictions, and in public investment due to corruption and bureaucratic inefficiencies, have both been suggested as important factors in accounting for the cross-country per capita income distribution. We introduce two modifications to the standard...

The two-sector specific factor model is typically used in the theory of international trade where it helps to clarify the principle of comparative advantage. Instead, we use this model as explicit theoretical framework to explain major trends of long-run economic development. Combined with...

We study how mortality reductions and income growth interact, looking at their relationship prior to the Industrial Revolution, when income per capita was stagnant. We first present a model of individual medical spending giving a rationale for individual health expenditures even when medicine...

The distribution of asset holdings among US banks is increasingly concentrated toward a few large banks at the top. Concurrently, the household wealth inequality has increased. This paper provides a theoretical link between these empirical facts, by developing a novel quantitative general...

Although the determinants of income are complex, the results are surprisingly uniform. To a first approximation, top incomes follow a power-law distribution, and the redistribution of income corresponds to a change in the power-law exponent. Given the messiness of the struggle for resources, why...

We study the rent-seeking phenomenon using a simple, static general equilibrium model. The economy consists of two sectors, both employing a constant returns-to-scale technology with labor as its sole input. One of the sectors is a monopoly, where a continuum of agents compete for a share of...

The traditional emphasis on breaking down output growth according to growth in inputs and growth in TFP is misplaced. More appropriately, we should break it down according to changes in "efficiency" and "technology". These two are equilibrium concepts, rather than purely technical properties of...

The publication of the book Capital in the Twenty-First Century by Piketty helped to increase the debate about the prospects of the evolution of income and wealth inequality in this century. One of the main controversies is about the effects to the income and wealth inequalities of a decrease in...

Despite economic growth in the post-World War II period, few developing countries have been able to catch up to the income levels in the United States or other advanced economies. Such countries remain trapped at a relative low- or middle-income level. In this article, the authors redefine the...
