This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....

This paper studies the implications of internal consumption habit for propagation and monetary transmission in New Keynesian dynamic stochastic general equilibrium (NKDSGE) models. We use Bayesian methods to evaluate the role of internal consumption habit in NKDSGE model propagation and monetary...

This paper reflects on the development leading to the recent crisis and interprets this development as a series of events within a Minsky-Veblen Cycle. To illustrate this claim we introduce conspicuous consumption concerns, as described by Veblen, into a stock flow consistent Post Keynesian...

This paper extends the theoretical concept of wage-led and profit-led demand regimes, first introduced by Amit Bhaduri and Steven Marglin in the early 1990s, by incorporating relative consumption concerns. Specifically, it integrates the Veblenian concept of conspicuous consumption into a...

We consider an economy where individuals face uninsurable risks to their human capital accumulation and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

The principle of effective demand, and the claim of its validity for a monetary production economy in the short and in the long run, is the core of heterodox macroeconomics, as currently found in all the different strands of post-Keynesian economics (Fundamentalists, Kaleckians, Sraffians,...

In recent research age distribution effects on the current account have been found in cross-country panel regressions. The reason is different effects on saving and investment from cohort-size variation. In a panel of annual OECD data 1960-1995, we find that the age effects on saving are similar...

We use a quantitative equilibrium model with houses, collateralized debt and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one fourth and one third of the increase in...

This document summarizes the thrust of my monograph book Disasters and the Networked Economy (2003, NY: Routledge. 228 pp. ISBN: 978-0-415-66629-9). It is no substitution for the book, but it attempts to make salient the main concepts, explanations and conclusions of it. It does so by first...

We document that U.S. employment polarization in the 1980-2008 period is largely generated by women. Female employment shares increase both at the bottom and at the top of the skill distribution, generating the typical U-shape polarization graph, while male employment shares decrease in a more...
