|November 2018||An Analysis of Puerto Rico's Debt Relief Needs to Restore Debt Sustainability|
with Pablo A. Gluzmann, Joseph E. Stiglitz: w25256
This paper makes two contributions. First, we examine the macroeconomic implications of Puerto Rico’s Fiscal Plan that was certified in March 2017 for fiscal years 2017-18 to 2026-27. Second, we perform a Debt Sustainability Analysis (DSA) that incorporates the expected macroeconomic dynamics implied by the Fiscal Plan in order to compute Puerto Rico’s debt restructuring needs. We detect a number of flawed assumptions in the Fiscal Plan that lead to an underestimation of its contractionary effects on the island’s economic activity. We conduct a sensitivity analysis of the expected macroeconomic dynamics implied by the plan that allows us to construct more realistic scenarios of Puerto Rico’s debt restructuring needs. We show that the island’s current debt position is unsustainable, and com...
|September 2017||Real Exchange Rate Policies for Economic Development|
with Jose Antonio Ocampo, Joseph E. Stiglitz: w23868
This paper analyzes the role of real exchange rate (RER) policies in promoting economic development. Markets provide a suboptimal amount of investment in sectors characterized by learning spillovers. We show that a stable and competitive RER policy may correct for this externality and other related market failures. The resulting development of these sectors leads to overall faster economic growth. A system of effectively multiple exchange rates is required when spillovers across different tradable sectors differ. The impact of RER policies is increased when they are complemented by traditional industrial policies that increase the elasticity of the aggregate supply to the RER. Among the instruments required to implement a stable and competitive RER are interventions in the foreign exchan...

|November 2016||Pseudo-wealth and Consumption Fluctuations|
with Joseph E. Stiglitz: w22838
This paper provides an explanation for situations in which the state variables describing the economy do not change, but aggregate consumption experiences significant changes. We present a theory of pseudo-wealth—individuals’ perceived wealth that is derived from heterogeneous beliefs and expectations of gains in a bet. This wealth is divorced from real assets that may exist in society. The creation of a market for bets will imply positive pseudo-wealth. Changes in the differences of prior beliefs will lead to changes in expected wealth and hence to changes in consumption, implying ex-post intertemporal individual and aggregate consumption misallocations and instabilities. Thus, in the environment we describe, completing markets increases macroeconomic volatility, raising unsettling welfar...
