DESCRIPTION:*Low-income countries are increasingly establishing intellectua
 l property rights (IPR) for plant varieties as a means to encourage innovat
 ion in crop technologies. Whether such policies spur agricultural developme
 nt is unclear: On one hand\, IP protection can bring new crop technologies 
 to markets\, expanding the set of plant varieties with agronomic traits tha
 t benefit farms. On the other hand\, the policy can raise input prices and
  reshape informal markets for traditional seed. This paper studies these tr
 adeoffs in a context of a landmark reform that strengthened IP protection f
 or plant varieties in Tanzania. I first combine the universe of registered 
 plant varieties released in the national market with an event study to esta
 blish that IP protection brought in new plant varieties. I then estimate th
 e effect of the arrival of these patented technologies on agricultural outc
 omes using rich farm-level data and a shift-share design that leverages t
 he staggered release of new varieties and agro-climatic variation in crop s
 uitability across regions. I find that the policy lifted supply-side constr
 aints: a 1SD increase in exposure to patented technologies boosted adoption
  of improved varieties by 6.7 percentage points. However\, the resulting pr
 oductivity gains were unevenly distributed: the policy delivered higher yie
 lds\, crop revenues\, and profits for larger and better-connected farms\, 
 while small and remote farmers experienced little to no benefit. Supporting
  evidence points to two channels that explain the unequal gains from adopti
 on: rising seed prices in local markets and small farmers’ inability to a
 djust use of land\, labour\, and material inputs that complement new techno
 logies.**This paper investigates how European equity mutual funds strategic
 ally combine multiple sustainability-related signals (such as adopting sust
 ainability-themed names\, obtaining ESG labels\, or providing sustainabilit
 y-oriented disclosures) and how the adoption of these signals affects inves
 tor flows. While prior literature typically evaluates individual signals in
  isolation\, this study examines their interaction and potential diminishin
 g or complementary effects when adopted jointly. By doing this\, the study 
 contributes to a more granular understanding of sustainable fund signaling 
 strategies and provides a framework to assess how multiple sustainability c
 laims collectively shape market perception and capital allocation.\\n\\nCon
