Price Discounts and Cheapflation During the Post-Pandemic Inflation Surge
We study how price variation within a store changes with inflation, and whether households exploit these changes to reduce the burden of inflation. We find that price changes from discounts mitigated the inflation burden while cheapflation exacerbated it. -
Markups and Inflation in Oligopolistic Markets: Evidence from Wholesale Price Data
We study how the interaction of market power and nominal price rigidity influences inflation dynamics. We find that pass-through declines with price stickiness when markets are concentrated, which implies a lower slope of the New Keynesian Phillips curve. -
Flagship Entry in Online Marketplaces
In this paper, we empirically study how flagship entry in an online marketplace affects consumers, the platform, and various sellers on the platform. We find flagship entry may benefit consumers by expanding the choice set, by intensifying price competition within the entry brand, and by improving consumer perception for parts of the platform. -
Measuring the Effectiveness of Salespeople: Evidence from a Cold-Drink Market
Salespeople are widely employed in many industries. We leverage a unique data set on retail sales from a leading Chinese cold-drink manufacturer and information on the firm’s salespeople assignment rule to measure the causal effect of salespeople on product revenue. -
The Effects of Government Licensing on E-commerce: Evidence from Alibaba
How does government licensing affect selling on online platforms? We examine the impact of China’s 2015 Food Safety Law on sellers and buyers on Alibaba, the largest e-commerce platform in that country. -
Overlooking the online world: Does mismeasurement of the digital economy explain the productivity slowdown?
Since the mid-2000s, labour productivity has slowed down in Canada despite enormous technological advances that were expected to improve it. This note investigates whether mismeasurement of the digital economy can explain this paradox. -
Distributional Effects of Payment Card Pricing and Merchant Cost Pass-through in Canada and the United States
Although credit cards are more expensive for merchants to accept than cash or debit cards, merchants typically pass through their costs evenly to all customers. Along with consumer card rewards and banking fees, this creates cross-subsidies between payment methods. Because higher-income individuals tend to use credit cards more than those with lower incomes, our results indicate that these cross-subsidies might lead to regressive distributional effects. -
Technology Adoption in Input-Output Networks
We study how input-output networks affect the speed of technology adoption. In particular, we model the decision to adopt the programming language Python 3 by software packages. Python 3 provides advanced features but is not backward compatible with Python 2, which implies it comes with adoption costs. -
Amazon Effects in Canadian Online Retail Firm-Product-Level Data
I use firm-product-level data for Canadian online retailers to study how product scope (the average number of product categories per firm) evolved from 1999 to 2012. During this period, product scope dropped monotonically from 59 to 5 product categories.
