Última Product Life Cycles and Innovation in the US Seed Corn Industry AgEcon Magnier, Alexandre; Kalaitzandonakes, Nicholas G.; Miller, Douglas J.. The purpose of this study is to evaluate potential changes in the length of product life cycles in the US seed corn industry. We use the observed survival time on the market for hybrids sold during 1997-2009 to conduct a survival analysis. Our empirical results show that the average lifetimes of conventional and biotech corn hybrids have decreased over the last twelve years at similar rates and that the rate of decline in the life cycle length increased since 2004. We also find that the shorter product life cycles are closely linked to the accelerated levels of biotech product innovation in the US seed corn industry observed over the period of the analysis.

Ano: 2010 URL: http://purl.umn.edu/61779 Product Life Cycles and Innovation in the US Seed Corn Industry AgEcon Magnier, Alexandre; Kalaitzandonakes, Nicholas G.; Miller, Douglas J.. The purpose of this study is to evaluate potential changes in the length of product life cycles in the US seed corn industry. We use the observed survival time on the market for hybrids sold during 1997-2009 to conduct a survival analysis. Our empirical results show that the expected lifetimes for corn hybrids with single biotech traits are 5-15% longer than for hybrids with multiple (stacked) traits, and the expected lifetimes for conventional corn are 13-17% longer than stacked hybrids. Also, the product life cycles for all types of hybrids have decreased over the past twelve years (especially after 2004), but the rate of decline is roughly similar across hybrid types. Based on this evidence, we conclude that the shorter product life cycles are closely...

Ano: 2010 URL: http://purl.umn.edu/93557 Market and Welfare Effects of Trade Disruptions from Unapproved Biotech Crops AgEcon Magnier, Alexandre; Konduru, Srinivasa; Kalaitzandonakes, Nicholas G.. Genetically modified (GM) crops have been largely adopted in major exporting countries thereby representing a dominant share of a few key agricultural commodities that are traded in international markets. Regulatory reviews and approvals for the cultivation and marketing of GM crops, however, are country-specific and significant discrepancies in the amount of time required to review and approve new GM crops between importing and exporting countries has led to “asynchronous approvals”. Trade disruptions created by asynchronous approvals of GM crops are expected and can quickly deteriorate into effective trade bans because perfect segregation between approved and unapproved GM crops is difficult. The issues we examine in this paper are the potential market...

Ano: 2004 URL: http://purl.umn.edu/93693 GMO Testing Strategies and Implications for Trade: A Game Theoretic Approach AgEcon Konduru, Srinivasa; Kalaitzandonakes, Nicholas G.; Magnier, Alexandre. Since their commercial introduction in 1996, genetically modified (GM) crops have been quickly adopted world wide, but some GM crops/varieties have not received regulatory approval for use in some importing countries, leading to asynchronicity in regulatory approvals. In this context, the international agricultural trade relied on analytical GMO testing which is a statistical process, along with identity preserved systems to segregate GM and non-GM crops. This led to a situation where measurement uncertainty became an important issue as it can lead to potential holdups at the point of import. In this background, this paper examines the implications of measurement uncertainty associated with GMO testing on the behavior of importers and exporters in a game...
