This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

An informal model is described that leads to multiple macroeconomic equilibria as a consequence of random variation in the relative amounts of technological change for new and existing goods. The novel observation is that the rate of introduction and market penetration of new goods vis-a-vis...

Empirical data is presented suggesting that high private and, to a lesser extent, public debt levels place a strong drag upon economic growth. A simple, demand-based, cash flow (DBCF) model of the economy is developed, separating out flows by marginal propensity to spend. This approach is both...

The currencies of nations, in their utility as a medium of exchange and store of value, behave variously according to the integrated dynamics of free enterprise, the central bank and government policy. As such, foreign exchange rates fluctuate constantly with consequences for the growth of...

Rising income and wealth inequality across the developed world has prompted a renewed focus on the mechanisms driving inequality. This paper contributes to the existing literature by studying the impact from life-cycle savings, intergenerational transfers, and fertility differences between the...

The two Cambridge controversy have marked a milestone in economic thinking. By their demonstration neo-Ricardian and post-Keynesian seemed to have proven the impossibility of defining the notion of Capital and, moreover, of being able to aggregate heterogeneous Capital. It is not so.By reasoning...
