Research by topic

I.  AGGREGATE DEMAND: Everything you (I) always wanted to know about T⋅HANK - but were too afraid to ask

SLIDES to teach (Tractable) T⋅HANK and summarize my research on it back to my earliest work starting 2004

2. The New Keynesian Cross Forthcoming, Journal of Monetary Economics with Online Appendix (Accepted w/ major revisions April 2018) June 2018 version; First CEPR DP version April 2017; First draft based on keyone lecture "Hand-to-mouth Macro" ERMAS Cluj July 2015; Previous subtitles: Understanding Mon. Pol. with: Hand-to-Mouth, or Two Agents (SLIDES nested above)

3. Optimal Monetary Policy and Liquidity with Heterogeneous Households, with Ragot, Oct 2017 (first Feb. 2016); Previously "Mon.Pol. and Inequality when Agg.Demand depends on Liquidity", then "Inequality, Liquidity, and Optimal Monetary Policy"

All the above stem from & build on (in the context of HANK) Ch.1 of my 2004 PhD thesis (ECB-WP 408/2004, Nuffield WP 09-2005, the first analytical TANK published as:

4. Limited Asset Market Participation, Monetary Policy and (Inverted) Aggregate Demand Logic, Journal of Economic Theory, 2008 Short 2-page summary here (all you need to understand the key mechanism)Slide (also included as first slides above).

The 2005 working-paper version here (title "... Keynesian Logic") formalized, to the best of my knowledge for the first time, a "Keynesian cross" with heterogeneity in Section 2.

The version posted above emphasizes the elements that substantiate this paper's contributions (in light of the subsequent developments in the literature) as the first to (1) build an NK model with two agents (analytical TANK) modelling the distinction as: profits and Euler equation (hold assets) versus lack thereof, aka hand-to-mouththus emphasizing the key role of profits' distribution for aggregate demand (AD) amplification; (2) derive an aggregate Euler-IS (and a 3-equation TANK nesting RANK) featuring AD amplification of monetary policy MP effects with hand-to-mouth through the key role of the elasticity of individual income to aggregate income; (3) analyze the role of fiscal redistribution (of profits) for AD amplification of MP; and (4) derive a quadratic welfare function and do optimal policy in TANK.
2018 Corrigendum for 1. elasticity of individual consumption to aggregate income under fiscal redistribution of profits; and 2. second-order approx. of aggregate welfare function for optimal policy.
