In this study, we prove how Shopify Capital (one of our first machine learning products) has real-world impact by making merchant funding accessible.
Overview
The article explores the impact of Shopify Capital on business growth using Propensity Score Matching (PSM) to analyze data from merchants. It details the methodology employed to assess the effect of funding on gross merchandise value (GMV) and concludes that Shopify Capital significantly boosts sales for merchants.

Key Questions Answered
What is the impact of Shopify Capital on merchants' sales?
Shopify Capital has a significant positive effect on merchants' sales, with US merchants experiencing a 36% higher geometric average of cumulative six-month gross merchandise value (GMV) after taking Capital compared to their Canadian counterparts. The confidence interval for this effect ranges from 13% to 65%, indicating a robust impact.
How does Propensity Score Matching work in this context?
Propensity Score Matching (PSM) is used to create a control group of Canadian merchants who would have used Shopify Capital if it were available. By matching these merchants with US merchants who accepted Capital, the study aims to estimate the causal effect of the funding on sales growth.
What methodology was used to ensure the quality of matching?
The article describes using standardized mean differences, visual diagnostics, and variance ratios to assess the balance of covariates between the treatment and control groups. This ensures that the matched groups are comparable and that the results are valid.
What assumptions were made in the analysis?
Key assumptions included that Canadian shops did not take offers solely because Capital was unavailable, that both US and Canadian shops had equal access to external financing, and that the operational environments for both groups were similar.

Key Actionable Insights
1Implement Propensity Score Matching in your data analysis to reduce bias when evaluating treatment effects.This method is particularly useful when randomization is not feasible, allowing for a more accurate comparison of treatment and control groups.
2Regularly assess the quality of your matching methodology to ensure valid results.Using techniques like standardized mean differences and visual diagnostics can help confirm that your treatment and control groups are comparable, which is crucial for drawing accurate conclusions.
3Consider the implications of external factors when analyzing treatment effects.Understanding the context in which your data was collected, such as market conditions or availability of funding, can help clarify the results of your analysis.
Common Pitfalls
1
Failing to properly match treatment and control groups can lead to biased results.
It's crucial to ensure that the groups are comparable in terms of key characteristics to draw valid conclusions about the treatment effect.
2
Ignoring external factors that may influence the results can skew the analysis.
Factors such as market conditions or access to other funding sources should be considered to avoid misinterpretation of the data.
