Open Variety Rights refer to the removal of the conditions attached to the usage of plants in agriculture, and to an analogy with open licensing in informatics that is notably different from the one that is taking shape at the intersection of the life sciences and informatics. This paper argues for the open licensing of plants as part of a response to the commodification of DNA; rather than a singular focus on farming or source code, this implies an analogy that aims at the removal of restrictions, whether as seeds, biodiversity, genetic sequences or DNA in informatics formats. First, the commodification of plants will be conceptualized. Second, the proposal for open licensing for varieties of crops will be discussed. Third, examples of the introduction of open licensing in the life sciences will be examined in relation to the potential to reformulate the definition of ‘openness’ to support those who wish to live and work with plants on their own terms. 相似文献

This paper extends the asymptotic theory of GMM inference to allow sample counterparts of the estimating equations to converge at (multiple) rates, different from the usual square-root of the sample size. In this setting, we provide consistent estimation of the structural parameters. In addition, we define a convenient rotation in the parameter space (or reparametrization) to disentangle the different rates of convergence. More precisely, we identify special linear combinations of the structural parameters associated with a specific rate of convergence. Finally, we demonstrate the validity of usual inference procedures, like the overidentification test and Wald test, with standard formulas. It is important to stress that both estimation and testing work without requiring the knowledge of the various rates. However, the assessment of these rates is crucial for (asymptotic) power considerations.Possible applications include econometric problems with two dimensions of asymptotics, due to trimming, tail estimation, infill asymptotic, social interactions, kernel smoothing or any kind of regularization. 相似文献

Many takeovers occur after one-on-one negotiations, which suggests a troubling lack of competition. We seek to determine whether acquirers in such friendly deals are truly insulated from competitive pressures. We study two countervailing influences: (1) potential but unobserved latent competition, i.e., the likelihood that rival bidders could appear, and (2) anticipated auction costs when negotiations fail. Using various proxies, we find that latent competition increases the bid premium offered in negotiated deals and that auction costs reduce the premium. 相似文献

In 1993, Californians voted on a school voucher initiative. We hypothesize that homeowners in good school districts understood the voucher to be a threat to their property values and thus voted against it. Precinct returns from Los Angeles County confirm this hypothesis. We also examine an alternative hypothesis explaining the relationship between school quality and precinct returns. According to the alternative, voters perceived the initiative to be a referendum on public school quality. To distinguish between the two hypotheses, we compare the voting patterns of homeowners and renters. The comparison does not favor one hypothesis over the other. 相似文献

Abstract: Several strategies are open to an economy in its attempt to attain sustainable economic development, depending on its historical background and resource endowment. One such strategy is the resource‐led strategy. Nigeria is very rich in crude oil and has reaped billions of petrodollars. However, the country faces the problem of successfully translating this huge oil wealth into sustainable development. This paper employs the vector error correction technique in examining the long‐run impact of the huge oil wealth accruing to Nigeria on its economic development. Basic indicators such as growth, private consumption, infrastructure (electricity), agriculture and manufacturing output growth rates are examined. The empirical results suggest a significant positive long‐run impact of per capita oil revenue on per capita household consumption and electricity generation while a negative relationship is established for GDP, agriculture and manufacturing. Even for those with a negative relationship at current period, there exist positive relationships at subsequent lags. Thus, oil revenue, if properly managed and invested, could be effectively used to induce oil‐led development for Nigeria provided that the initial inhibitions of corruption, lack of transparency, accountability and fairness in its use and distribution are removed. 相似文献

Labor productivity, wages, nationality, and foreign ownership shares in Thai manufacturing, 1996–2000 总被引:1,自引:1,他引:0
This paper compares labor productivity and wages among nationality and ownership groups of foreign multinational corporations (MNCs) and local plants in Thai manufacturing for 1996, 1998, and 2000. Disaggregating foreign MNCs by nationality or foreign ownership share revealed a few significant differences in both labor productivity and wages that were not present in more aggregate specifications. In these cases, there was a weak tendency for MNCs from Europe, Japan, and the United States to have relatively high labor productivity and wages, for wholly-foreign MNCs to have relatively high labor productivity, and for majority- and wholly-foreign MNCs to pay relatively high wages. However, these results suggest that the relationships among labor productivity or wages, on the one hand, and nationality or foreign ownership shares, on the other hand, were generally weak in Thai manufacturing. These results are also consistent with those of previous studies in suggesting that the relationship between labor productivity and foreign ownership in general was also rather weak, though the relationship between wages and foreign ownership was somewhat stronger. 相似文献
