Contrary to the neoclassical model’s assumptions, shifts in aggregate demand have persistent effects on GDP

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).

Over the next year, the Bitcoin price could double, soar tenfold, or collapse by 95% or more, and no economic analysis can help predict where in that range it will lie. Like other cryptocurrencies, Bitcoin serves no useful economic purpose, though in macroeconomic terms, such currencies probably also do little harm.

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.

Contrary to conventional wisdom, government stimulus can improve the health of the economy for years after, without inflationary side effects 

Forget the myth of a savings glut causing near-zero interest rates. We have a shortage of aggregate demand, and only public spending and raising wages will change that.

Summers discusses inequality, the GOP tax plan, and our economic future

Servaas Storm’s commentary on the papers presented at the secular stagnation conference.

Inequality isn’t driven by taxes—it’s driven by the power of capital in relation to workers

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.
