This paper provides a theoretical and empirical reassessment of supermultiplier theory. First, we show that, as a result of the passive role it assigns to investment, the Sraffian supermultiplier (SSM) predicts that the rate of utilization leads the investment share in a dampened cycle or,...

This paper shows how uninsurable unemployment risk is crucial to qualitatively and quantitatively match macro responses to uncertainty shocks. Empirically, uncertainty shocks i) generate deflationary pressure; ii) have considerably negative consequences on economic activity; iii) produce a drop...

The strongest predictor of changes in the Fed Funds rate in the period 1982–2008 was the layoff rate. That fact is puzzling from the perspective of representative-agent models of the economy, which imply that the welfare gains of stabilizing employment fluctuations are small. This paper...

This paper develops a DSGE model with downward nominal wage rigidity, in which aggregate price and productivity dynamics are exogenously determined by independent Brownian motions with drift. As a result, the long-run expected value of unemployment depends positively on the drift coefficients...

Japan has suffered from sluggish economic growth and recession since the early 1990s. In this paper, we analyze the causes of the prolonged slowdown of the Japanese economy (the lost decade). Economics Nobel laureate Paul Krugman has argued that Japan's lost decade is an example of a liquidity...

This paper studies two formal models of long run growth with a medium-run distributive cycle, both of which feature causal links from the rise in inequality to a deterioration of long run macroeconomic performance. Both versions feature an endogenous income-capital ratio: one through the...

This paper proposes a non-linear New Keynesian Phillips curve (Inv-L NK Phillips Curve) to explain the surge of inflation in the 2020s. Economic slack is measured as firms' job vacancies over the number of unemployed workers. After showing empirical evidence of statistically significant...

It is often asserted that, whatever role Keynesian policies may have played in underpinning the long post-war boom, those policies are no longer relevant. In contrast this paper seeks to reassert the need for Keynesian policies in order to secure full employment. In doing so, as will be seen...

This paper develops an overlapping-generations model with nominal wage rigidities and examines the welfare effects of debt policy when unemployment exists. Issues of public debt stimulate aggregate consumption demand and create employment. Future generations then face both increased wage incomes...

Many empirical studies have found that interest rate increases have a positive effect on the price level. This paper pursues an obvious, but neglected explanation: interest payments are a cost of production that is at least in part passed on to customers. A model shows that the cost-push effect...
