On the Endogeneity of Inflation Targeting: Preferences Over Inflation

Over the last quarter of a century, inflation targeting has become a popular monetary regime. Nevertheless, empirical evaluations of IT have shown contradictory results. Part of the reason is that IT in and of itself constitutes an endogenous decision and thus needs to be properly instrumented. In this paper, we show that preferences over inflation constitute a crucial determinant of IT: countries exhibiting greater inflation aversion are more likely to adopt IT.Inflation targeting, Monetary Policy, Monetary Regimes

Unemployment in Latin America and the Caribbean

This study constructs a new data set on unemployment rates in Latin America and the Caribbean and then explores the determinants of unemployment. We compare different countries, finding that unemployment is influenced by the size of the rural population and that the effects of government regulations are generally weak. We also examine large, persistent increases in unemployment over time, finding that they are caused by contractions in aggregate demand. These demand contractions result from either disinflationary monetary policy or the defense of an exchange-rate peg in the face of capital flight. Our evidence supports hysteresis theories in which short-run changes in unemployment influence the natural rate.unemployment, hysteresis, monetary policy, Latin America and theCaribbean.

El desempleo en América Latina y el Caribe

Este estudio construye nuevas series de tasas de desempleo para Latinoamérica y el Caribe y estudia sus determinantes. Al comparar diferentes países encontramos que el desempleo está influenciado por el tamaño de la población rural y que los efectos de las regulaciones gubernamentales son generalmente débiles. También examinamos aumentos prolongados y persistentes del desempleo en el tiempo y encontramos que se originan en contracciones de la demanda agregada. Estas contracciones son el resultado ya sea de políticas monetarias desinflacionarias o de la defensa de una tasa de cambio fija ante salidas de capital. Nuestra evidencia da soporte a las teorías de histéresis según las cuales cambios de corto plazo en la tasa de desempleo influencian su tasa natural.desempleo, histéresis, política monetaria, América Latina y el Caribe.

Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.

Deposit insurance and depositor behavior: evidence from Colombia

This paper studies the effect of deposit insurance on depositor behavior. Our theoretical framework integrates insights from public and financial economics and predicts that (1) deposit insurance induces bunching at the threshold in the deposit distribution and (2) an increase in the insurance threshold promotes deposit growth, particularly higher for individuals bunching at the initial limit. We exploit a large and unexpected increase in the Colombian insurance together with monthly depositor-level records from a major bank to test these predictions. We validate the existence of bunching in deposits and quantify the heterogeneous effect of deposit insurance on individual deposit growth
