This paper presents a comprehensive framework examining fiscal sustainabil- ity in developing economies. It integrates public capital, labor informality, and global liquidity shocks in a two-sector DSGE model for a small open economy, revealing their intricate interplay and nonlinear impact on...

Why do individuals' preferences for redistribution often diverge widely from their material self-interest? Using an original online survey experiment spanning eight countries and 12,000 respondents across Latin America, one of the most unequal regions in the world, we find significant evidence...

We argue that the fiscal multiplier of government purchases is increasing in the spending shock, in contrast to what is assumed in most of the literature. The fiscal multiplier is largest for large positive government spending shocks and smallest for large contractions in government spending. We...

We build a tractable heterogeneous-agent incomplete-markets model with quasi-linear preferences to address a set of long-standing issues in the optimal Ramsey taxation literature. The tractability of our model enables us to analytically prove the existence of a Ramsey steady state and establish...

What is the prescription of Ramsey capital taxation in the long run? Aiyagari (1995) addressed the question in a heterogeneous-agent incomplete-markets (HAIM) economy, showing that a positive capital tax should be imposed to implement the so-called modified golden rule (MGR). This paper revisits...

We analyze the effectiveness of an increase in government consumption for stimulating growth for diverse levels of public debt in the European Union. We conclude, that growth rate can be stimulated in the short run by an increase in government consumption but only at low levels of public debt....

This paper addresses a long-standing problem in the optimal Ramsey capital taxation literature. The tractability of our model enables us to solve the Ramsey problem analytically along the entire transitional path. We show that the conventional wisdom on Ramsey tax policy and its underlying...

In order to enhance fiscal sustainability and regain “investment grade” credit rating, in 2011 Colombia implemented a fiscal rule (FR) on the Central Government's structural balance. Investment grade was rapidly attained, and FR targets were complied with, until 2019. Using the Synthetic...

The aggregate capital stock in a nation can be overaccumulated for many different reasons. This paper studies which policy or policy mix is more effective in achieving the socially optimal (golden rule) level of aggregate capital stock in an infinite-horizon heterogeneous-agents...

The rapidly growing national debt in the U.S. since the 1970s has alarmed and intrigued the academic world. Consequently, the concept of dynamic (in)efficiency in an overlapping generations (OLG) world and the importance of the heterogeneous-agents and incomplete markets (HAIM) hypothesis to...
