If one ranks cities by population, the rank of a city is inversely related to its size, a well-documented phenomenon known as Zipf's Law. Further, the growth rate of a city's population is uncorrelated with its size, another well-known characteristic known as Gibrat's Law. In this paper, I show...

Choices are frequently made from lists where there is by necessity some ordering of options. In such situations individuals can exhibit both primacy bias towards the first option and recency bias towards the last option. We examine this phenomenon in a particularly interesting context: consumer...

This paper evaluates the role of sectoral heterogeneity in determining the gains from trade. We first show analytically that in the presence of sectoral Ricardian comparative advantage, a one- sector sufficient statistic formula that uses total trade volumes as a share of total absorption...

While there has been significant research to explore the determinants (and frictions) of foreign direct investment (FDI), past literature primarily focuses on country-wide FDI patterns with little examination of sectoral heterogeneity in FDI. Anecdotally, there is substantial sectoral...

Research on the geographical distribution of international portfolios has mainly focused on data aggregated to the country level. We exploit newly-available data that disaggregates the holders and issuers of international securities along sectoral lines. We find that patterns evident in the...

It has long been recognized that a country's tariffs are the endogenous outcome of a rent-seeking game whose equilibrium reflects national institutions. Thus, the structure of tariffs across industries provides insights into how institutions, as reflected in tariff policies, affect long-term...

We study e-commerce across 47 economies and 26 industries during the COVID-19 pandemic using aggregated and anonymized transaction-level data from Mastercard, scaled to represent total consumer spending. The share of online transactions in total consumption increased more in economies with...

This paper assesses the quantitative importance of including sectoral heterogeneity in computing the gains from trade. Our framework draws from Caliendo and Parro (2015) and has sectoral heterogeneity along five dimensions, including the elasticity of trade to trade costs. We estimate the...

The relative price of services rises with development. A standard interpretation of this fact is that productivity differences across countries are larger in manufacturing than in services. The service sector comprises heterogeneous categories. We document that many disaggregated service...
