| This paper examines how the traditional carp sector in Poland developed during the recent period, paying a particular attention to the different forms of innovations that have been implemented. Mostly based on first-hand, face-to-face interviews, the paper shows that despite the fact that aquaculture of carp is still characterised by strong traditional and cultural features, different categories of economic agents along the value-chain engaged in various kinds of technical, market and institutional innovations. These innovative strategies could be further replicated and developed through collaborative process, where policy makers have a potential role to play. The research results showed the existence of huge potential for innovation in traditional carp... |

| The nearly neutral theory of molecular evolution predicts that small population size is essential for non-adaptive evolution. Evolution of whole-body left-right reversal in snails is generally a compelling example of non-adaptive speciation, because variants with reversed chirality would suffer from reduced mating opportunities within a population. Despite this reproductive disadvantage, sinistral snail species have repeatedly originated from dextral ancestors in terrestrial pulmonates. Here I show that snail speciation by reversal has been accelerated on oceanic islands. Analysing the global biogeography of 995 genera across 84 stylommatophoran families, I found that the proportion of sinistral snail genera was enhanced in genera endemic to oceanic... |

| This teaching note accompanies the case study titled “Strategic Decision Making under Uncertainty: Innovation and New Product Introduction during Volatile Times” published under the reference: Boehlje, M. And M. Roucan-Kane, ”Strategic Decision Making under Uncertainty: Innovation and New Product Introduction during Volatile Times”, International Food and Agribusiness Management Review, 12 (4), 2009. This case study outlines the strategic, marketing, and organizational issues facing the farm machinery and equipment division of Deere and Company as it is considering the development of products in the information domain, which encompasses many opportunities of disruptive innovations to market to new or underserved customers. While these disruptive... |

| We study a quality-ladder model of endogenous growth that produces stochastic leadership cycles. Over a cycle, industry leaders can innovate several successive times in the same industry, gradually increasing the magnitude of their technological lead before being replaced by a new entrant. Initially, new leaders are eager to enlarge their lead and do much of the research, but if they innovate repeatedly, their propensity to invest in R&D decreases. Eventually they stop doing research altogether, and as they are overtaken a new cycle starts. The model generates a skewed firm size distribution and a deviation from Gibrat’s law that accord with the empirical evidence. We also consider various policy measures, showing that in some cases policy should... |

| We examine the allocation of technology rents between a price-setting, innovating monopolist and heterogeneous technology adopters. A model of monopoly pricing in the presence of heterogeneous adopters is used to examine conditions under which greater producer (farmer) heterogeneity leads to greater producer benefit from innovation in non-competitive markets. An application to Bt cotton determines the profit-maximizing price of Bt cotton seed and reveals that Monsanto and Delta and Pine Land are indeed leaving money on the table in the form of unexploited profit opportunities. However, we estimate that the presence of heterogeneous adopters explains over 80% of the rents that accrue to the farmers. |

| This paper describes a model for estimating, in a probabilistic framework, expected future consumer surplus from planned new product innovations. The model has been applied to estimations of taxpayer benefits from NASA's New Millenium Program (NMP), which develops new technologies for space science, and to the digital data storage technologies being supported by the Department of Commerce's Advanced Technology Program (ATP). The model uses cost index methods based on consumers' estimated marginal valuation for quality improvements in the technology. Probabilistic values for performance increases are taken from the innovators' own expectations. The analysis reveals the sensitivity of welfare increases to these values, which are assumed to be biased upward.... |
