Macroeconomic Implications of Uniform Pricing​​​

AEJ:Macro (Forthcoming)
with Julian Kozlowski ​
We compile a new database of grocery prices in Argentina. We find uniform pricing both within and across regions—i.e., prices almost do not vary within stores of a chain. In line with uniform pricing, prices in stores of chains operating in one region react to changes in regional employment, while prices in multi-region chains do not. Using a quantitative regional model with multi-region firms and uniform pricing, we find a one-half smaller elasticity of prices to a regional than an aggregate shock. This result highlights that some caution may be necessary when using regional shocks to estimate aggregate elasticities.

Explaining Intergenerational Mobility:
​The Role of Fertility and Family Transfers
​​​

Review of Economic Dynamics (2020)
with Julian Kozlowski ​
Poor families have more children and transfer less resources to them. This suggests that family decisions about fertility and transfers dampen intergenerational mobility. To evaluate the quantitative importance of this mechanism, we extend the standard heterogeneous-agent life-cycle model with earnings risk and credit constraints to allow for endogenous fertility, family transfers, and education. The model, estimated to the US in the 2000s, implies that a counterfactual flat income-fertility profile would—through the equalization of initial conditions—increase intergenerational mobility by 7%. The impact of a counterfactual constant transfer per child is twice as large.

The Surprising Instability of Export Specializations​​​

Journal of Development Economics (2019) 
with William Easterly and Ariell Reshef​
We study the instability of hyper-specialization of exports. We have two main findings. (1) Specializations are surprisingly un-stable: Export ranks are not persistent, and new top products and destinations replace old ones. Measurement error is unlikely to be the main or only determinant of this pattern. (2) Source-country factors are not the main explanation of this instability: Only 20% of the variation in export growth can be explained by variation in comparative advantage (source-by-product factors), while another 20% of the variation in export growth can be explained by variation in bilateral (source-by-destination) factors. The high share of product, destination, and product-by-destination factors, diminishes the emphasis on the nations where the exports originate. The high share of idiosyncratic variance (residual at the source-product-destination level of variation) of about 30%, also indicates the difficulty to predict export success using source country characteristics. These findings suggest that export performance depends, to a greater extent than previously appreciated, on forces that are outside the realm of national export promotion and industrial policies.

The Macroeconomic Consequences of Early Childhood
​Development Policies

Journal of Political Economy (R&R) 

​To study long-run large-scale early childhood policies, this paper incorporates early childhood investments into a standard general-equilibrium (GE) heterogeneous-agent overlapping-generations model. After estimating it using US data, we show that an RCT evaluation of a short-run small-scale early childhood program in the model predicts effects on children's education and income that are similar to the empirical evidence. A long-run large-scale program, however, yields twice as large welfare gains, even after considering GE and taxation effects. Key to this difference is that investing in a child not only improves her skills but also creates a better parent for the next generation.

​The Effects of Partial Employment Protection Reforms: Evidence from Italy

Review of Economic Studies (Cond. Accepted)
with Sabrina Di Addario and Raffaele Saggio  
We combine matched employer-employee data with firms' financial records to study a 2001 Italian reform that lifted constraints on the employment of temporary contract workers while maintaining rigid employment protection regulations for employees hired under permanent employment contracts.  Exploiting the staggered implementation of the reform across different collective bargaining agreements, we find that this policy change led to an increase in the share of temporary contracts but failed to raise employment significantly. The reform had both winners and losers. Firms are the main winners as the reform was successful in decreasing labor costs, leading to higher profits. By contrast, young workers are the main losers since their earnings were substantially depressed following the policy change. Rent-sharing estimates show that workers on a temporary contract receive only two-thirds of the rents shared by firms with workers hired under a permanent contract, helping to explain most of the firms' labor costs and workers' earnings reductions caused by the reform.

Universal Basic Income: A Dynamic Assessment​​​

With Raquel Fernandez
Universal basic income (UBI) is an increasingly popular policy proposal but there is no evidence regarding its longer-term consequences.  We study UBI in a general equilibrium model with imperfect capital markets, labor market shocks, and intergenerational linkages via skill formation and transfers. We find that UBI increases older agents' welfare but generates large welfare losses for younger agents and future generations. This conclusion is robust to various alternative ways of financing UBI.  A novel part of the analysis compares adjacent cohorts over the transition to show that a large share of the negative effects stem from the endogenous intergenerational linkages.

​An Equilibrium Analysis of the Effects of Neighborhood-based
​Interventions on Children​

With Eric Chyn
To study the effects of neighborhood and place-based interventions, this paper incorporates neighborhood effects into a general equilibrium (GE) heterogeneous-agent overlapping-generations model with endogenous location choice and child skill development. Importantly, housing costs as well as neighborhood effects are endogenously determined in equilibrium. Having calibrated the model using U.S. data, we use simulations to show that predictions from the model match reduced form evidence from experimental and quasi-experimental studies of housing mobility and urban development programs. After this validation exercise, we study the long-run and large-scale impacts of vouchers and place-based subsidies. Both policies result in welfare gains by reducing inequality and generating improvements in average skills and productivity, all of which offset higher levels of taxes and other GE effects. We find that a voucher program generates larger long-run welfare gains relative to place-based policies. Our analysis of transition dynamics, however, suggests there may be more political support for place-based policies.​
