"This paper studies how portfolios with a global investment scope are actually allocated internationally using a unique micro dataset on U.S. equity mutual funds. While mutual funds have great flexibility to invest globally, they invest in a surprisingly limited number of stocks, around 100. The...

In this paper, we develop a methodology to estimate hidden linear networks when only an aggregate outcome is observed. The aggregate observable variable is a linear combination of the different networks and it is assumed that each network corresponds to the transmission mechanism of different...

Matched product data is collected from the leading online grocers in the U.S. The same exact products are identified in scanner data. The paper documents pricing strategies within and across online (and offline) retailers. First, online retailers exhibit substantially less uniform pricing than...

Covid-19 highlighted the weaknesses in the supply chain. Many have argued that a more resilient or robust supply chain is needed. But what does a robust supply chain mean? And how do firms' decisions change when taken that approach? This paper studies a very stylized model of a supply chain,...

We use a novel dataset of online prices of identical goods sold by four large global retailers in dozens of countries to study good-level real exchange rates and their aggregated behavior. First, in contrast to the prior literature, we demonstrate that the law of one price holds very well within...

This paper studies pricing in the fashion retail industry. Online data was collected for approximately 350,000 distinct products from over 65 retailers in the U.S. and the U.K. We present evidence that a fair fraction of retailers implement an extreme form of price stickiness that we describe as...

How does ESG (environmental, social, and governance) performance affect stock returns? Answering this question is difficult because existing measures of ESG perfor- mance -- ESG ratings -- are noisy and, therefore, standard regression estimates suffer from attenuation bias. To address the bias,...

This paper estimates the effect of sustainable shareholder engagement on firm's investments. We study the real estate industry where investments are sporadic and occur following depreciation cycles. SEC restrictions (rule 240.14a-8) on shareholder proposals, in combination with the asset...

We study the daily behavior of supermarket prices and product availability following two recent natural disasters: the 2010 earthquake in Chile and the 2011 earthquake in Japan. In both cases there was an immediate and persistent effect on product availability. The number of goods available for...

During the last two decades, many Latin American countries engaged in disinflation programs based on both exchange rate management and fiscal reforms. However, in most instances, part of the fiscal reform was delayed or not implemented completely, so the fiscal deficit increased and the program...
