Credible Answers to Hard Questions: Differences-in-Differences for Natural Experiments This book introduces applied researchers to modern Differences-in-Differences (DID) methods, that they can use to obtain credible answers to hard causal inferen

Just posted updated version of our DID textbook! We now have drafts of all chapters, including the one on general designs! Now you can tell your friends still on X that they are DID-outdated :-) Happy easter for those of you that celebrate it. papers.ssrn.com/sol3/papers....

Hey BSKY friends! We will be heading out to conduct on-farm interviews with farmers this summer. Any recommendations on tablets/software for fieldwork you've used lately? Bonus points if they can log GPS coordinates!

The FEWS NET Website, the FEWS NET Learning Platform, and the FEWS NET Data Warehouse and Data Explorer are currently unavailable.

The US Famine Early Warning Systems Network (FEWS NET) website is now offline. Since 1985, FEWS NET has provided assessments of the location and severity of food crises. These assessments are used by gov and non-government humanitarian organizations across the world to allocate aid.

⚠️ Policy takeaway: While fertilizer subsidies are essential, high temperatures can undermine their effectiveness, shifting input priorities. Future policies should support broader adaptation strategies, including pest management. 9/10

πŸ§‘β€πŸŒΎ The findings indicate that both current and prior heat events influence how farmers allocate resources and adapt. This points to a need for policy approaches that support these adjustments. 8/10

For individual crops, heat impacts vary. Millet production, for example, declines under heat, while cowpea seems more resilient. Such varied responses suggest room for climate-focused crop choices. 7/10

A major adaptation response: mixed cropping. 🌾High temps lead farmers to diversify crops, adding resilience to their systems, though it might reduce potential yields. 6/10

🌱 Extreme heat shifts farmers' input use. Facing high temps, farmers move from yield-enhancing inputs, like fertilizers, to protective measures, like pesticides. They also rely more on hired labor after high-temp seasons.

πŸ” Key finding: high temps reduce crop yields but don’t lower the overall value of agricultural output. Why? Farmers adapt by expanding the cultivated area, compensating for yield losses. 4/10

Using data from the Nigeria LSMS-ISA (2010-2015), we investigate how current and past heat exposure impacts TFP, crop yields, cultivated areas, and input use. We combine farm data with high-res satellite temperature records. 2/10

Another edition of "All new work is elaborating on the old": an article in the latest QJE generates TFP estimates for England over six centuries & confirms the Nef Thesis of 1934. Before Crafts, before Wrigley, Nef had said most of it 90 years ago
