This paper presents a two-sector endogenous growth model where public spending -which is endogenous and productive- may generate equilibrium indeterminacy. Under certain mild conditions, there exists a continuum of expectations-driven equilibrium paths approaching a common balanced growth path....

We analyze a stochastic growth model with lags in the operation of new technologies. Stock values are impacted by news on technological innovations and some other external shocks affecting the economy. Episodes of technology adoption may generate long fluctuations in the aggregate value of...

This paper analyzes how changes in the firing-costs gap between permanent and temporary workers affect firms' TFP in a dual labour market. We argue that, under plausible conditions, firms' temp-to-perm conversion rates go down when this gap increases. Temporary workers respond to lower...

Eligibility and benefits for anti-poverty income transfers in the U.S. are based on both the means and the household characteristics of applicants, such as their filing status, living arrangement, and marital status. In this paper we develop a dynamic structural model to study the effects of the...

The Covid-19 pandemic has brought about changes in key income support programs, reigniting a debate about the design of financial aid to low-income households with children. In this study we assess the Family Security Act - a proposal presented by Senator Mitt Romney (R-UT) on February 4, 2021...

In this paper, we present a dynamic model of labor supply, consumption, savings and marital decisions where we embed the income tax schedule and the four main anti-poverty income transfer programs in the U.S. The model is calibrated to match moments from a sample of non-college-educated workers...

We characterize the optimal reform of U.S. income support for low-income single parents. We develop a heterogeneous agents model with idiosyncratic risk and incomplete asset markets where single parents evolve through three life stages defined by their children's care needs. Using the U.S....
