Working Papers

The prevailing wisdom that aggregate demand ‘shocks’ determine short-run cyclical fluctuations around a supply-determined equilibrium growth rate and an associated equilibrium unemployment rate (or NAIRU) has been called into question by various streams of literature in the last decades. Specifically, a recently revived literature on hysteresis finds significant persistence in the effects of recessions and negative aggregate demand shocks (Blanchard et al. 2015; Martin et al. 2015).

A critical analysis of Piketty’s work

A large literature has detailed the seminal roles played in the Civil Rights Movement by activists, new political organizations, churches, and philanthropies. But black-owned businesses also provided a behind-the-scenes foundation for the movement’s success.

The U.S. presidential election of 2016 featured frontal challenges to the political establishments of both parties and perhaps the most shocking election upset in American history.

To get justice, targets must show measurable harm: economists can help.

Veiling among Muslim women is modeled as a commitment mechanism that limits temptation to deviate from religious norms of behavior. 

The past 30 years has witnessed a worldwide decrease in real interest rates. We demonstrate that a large part of the fall in interest rates can be explained by changes in demography, which are as the result of a sudden fall in fertility rates across all of the advanced economies in the early 1970s.

We examine the hypothesis that the slowdown in productivity following the Great Recession was in significant part an endogenous response to the contraction in demand that induced the downturn.

The concern that an economy could experience persistent, and in some sense unusual, weakness goes back to Keynes’s General Theory and led Alvin Hansen to coin the term “secular stagnation.”

This paper shows that aging has positive effect on output growth per capital at positive interest rates, due to capital deepening.

We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by high unemployment and weak growth.

We explore the transmission mechanism of income inequality to output.

I have read the various conference papers and am struck by the fact that many use the (omnipresent New-Keynesian) model of an aggregate loanable funds market to diagnose secular stagnation and investigate possible remedies.

This paper answers fundamental questions that have preoccupied modern economic thought since the 18th century.

Long-term real interest rates across the world are low, having fallen by about 450 basis points (bps) over the past thirty years.
