Notwithstanding the ambiguous research and productivity promoting effects of plant variety protections (PVPs), even in developed countries, many developing countries have adopted PVPs in the past few years, in part to comply with their Trade-Related Aspects of Intellectual Property Rights...

Proponents tout the positive incentive-to-innovate effects of intellectual property rights (IPRs), while others maintain that the expanding subject matter and geographical extent of IPRs are stifling crop research, especially research and development (R&D) dealing with developing-country crop...

The United States was the first country in the world to explicitly offer intellectual property protection for plant varieties. Beginning in 1930, asexually reproduced plants were afforded plant patent protection, in 1970 sexually propagated plants could be awarded plant variety protection...

Prices of basic food staples and feed crops have soared in recent years, renewing concerns about the ability of global food supplies to meet the projected growth in aggregate demand. Notwithstanding these concerns, and apparently at odds with a vast body of economic evidence reporting...

Recent trends in farm productivity and food prices raise concerns about whether the era of global agricultural abundance is over. Agricultural R&D is a crucial determinant of agricultural productivity and production, and therefore food prices and poverty. In this paper we review past and present...

This is a prepublication version of J.M. Beddow, T.M. Hurley, P.G. Pardey, and J.M. Alston’s “Food Security: Yield Gap” chapter in N. Van Alfen, editor-in-chief, Encyclopedia of Agriculture and Food Systems, Vol. 3, San Diego: Elsevier, 2014, pp. 352-365.

Some studies have reported a slowdown in U.S. farm productivity growth, but the prevalent view among economists is to reject or downplay the slowdown hypothesis, implying that the rates of productivity growth experienced over the past half century can be projected forward. We set out to resolve...

Allocative decisions concerning public sector agricultural research appear to be driven by both supply and, politically mediated, demand forces. In-sample Granger and Modified Sim's tests, along with post-sample predictive tests, suggest that simultaneity issues should not be ignored when...
