Economists at the Federal Trade Commission (FTC) pursue the agency’s competition and consumer protection missions. In this
year’s essay, in antitrust, we discuss the new Merger Guidelines, three exclusion cases, and R&D issues in the Thoratec/HeartWare
merger and the Google/AdMob merger. In consumer protection, we discuss the FTC’s new rule on debt settlement, our efforts
to improve disclosures, and our recent work on appliance energy disclosures. 相似文献

Capital goods are embodied knowledge of how to produce. Therefore, capital development is a learning process, through which knowledge gets embodied in new capital goods. Because the necessary knowledge is dispersed among many people who must interact to communicate their particular, often tacit knowledge, capital development is a social process. Because this interaction takes time and continually changes the capital structure, capital development is an on-going process. Capital development is a social learning process. Neither traditional nor new growth theory illuminates how the capital structure evolves. Traditional growth theory, by modeling capital as single variable in the production function, ignores the heterogeneity of capital goods and their varied structural relationships of complementarity, substitutability, feedback, and feed-forward. New growth theory, while accounting for technological change, still treats capital as aggregable and thus implicitly homogeneous. That capital development is a learning process suggests that growth rates can increase. What prevents exponential growth is neither diminishing returns nor upper bounds to human capital, as growth models assume. It is the constant challenge of maintaining capital complementarities in a world of incomplete and rapidly changing knowledge. 相似文献

Factors influencing the uptake of a mechatronics curriculum initiative in five Australian secondary schools 总被引:1,自引:0,他引:1
While the ready-made Lego™ Robotics kits are popular in schools and are used by students at both primary and secondary year
levels, using the Picaxe microcontroller (chip) to create simple electronic devices, including robotic devices is less popular.
The latter imposes an additional challenge as a result of the need to construct the universal board with the chip in it—a
challenge embraced in the cross-disciplinary mechatronics program in this study. This paper reports on how teachers from five
Australian secondary schools put into practice technological pedagogical content knowledge (TPCK) developed from expert-led
workshops and explores factors (intrinsic and extrinsic) that influenced the implementation. The results show that different
strategies were adopted by the schools in implementing the programs. While teacher attitude played an important role in influencing
the program’s success, being able to identify where the program sits within the curriculum and planning around timetable and
facility constraints were also important factors to consider. The research indicated that teachers’ TPCK was most challenged
in non-obvious areas such as diagnosing where faulty soldering joints were. 相似文献

Using previously unexploited data, this paper explores the ages at which slaves were manumitted. OLS estimates reveal that mixed-race slaves, slaves in the tobacco-producing Piedmont, and female slaves of female slave owners were manumitted at younger ages. Weibull proportional hazards estimates imply that the same groups were more likely to be manumitted. The results also reveal a markedly diminishing likelihood of manumission after Nat Turner’s 1831 insurrection in south-central Virginia. The results are consistent with a principal–agent model in which slave owners contracted with slaves over consumption and future manumission to elicit effort and control shirking or other unproductive activities. 相似文献

In recent years, there has been a growing interest in the environmental impacts of trade liberalization. This paper provides further discourse in this area with a study on Indonesia and its trade agreements with Japan (IJEPA) and ASEAN (AFTA). A static global CGE model, known as the Global Trade Analysis Project, was used to project the Indonesian economy to the year 2022, with and without tariff reforms agreed under the agreements. Environmental impacts are assessed using different pollution indicators—air, water and waste. The study suggests that Indonesia would grow rapidly over the period considered with a large deterioration in its environment. Following these, however, the agreements only have a marginal positive impact on Indonesia's output but with a noticeable increase in trade flows and signs of trade diversion. Overall AFTA has a greater impact on the Indonesian economy compared to IJEPA. Similarly, the impact of trade liberalization on the environment is marginal. On the whole, tariff reform is inducing air pollution and reducing water pollution. In conclusion, the study suggests that Indonesia's participation in the AFTA and IJEPA agreements is not likely to bring drastic changes to her economic and environmental performance. 相似文献

When faced with the need to protect dealer provision of promotional services for their products, manufacturers have continued to impose resale price maintenance (RPM) in preference to providing exclusive territories, even though the latter are legal while RPM is not. This paper compares RPM and territories, finding that RPM raises retail prices by less, but also supports less service provision than the exclusive territories alternative. Indeed, exclusive territories raise prices and generate more services than full manufacturer integration into distribution. This result calls into question the current contrasting legal treatment of territories and RPM. 相似文献

One area of business performance of particular interest to both scholars and practitioners is corporate social responsibility. The notion that organizations should be attentive to the needs of constituents other than shareholders has been investigated and vigorously debated for over two decades. This has provoked an especially rich and diverse literature investigating the relationship between business and society. As a result, researchers have urged the study of the profiles and backgrounds of corporate upper echelons in order to better understand this relationship.There is ample evidence that corporations have in recent years increased the proportion of outside directors on their boards. This has been partly in reaction to increased interest in the corporate social responsiveness of business organizations and suggestions that the board of directors could play a unique role in this area. The expectation on the part of practitioners, researchers, and governmental regulators is that outside directors will advocate greater corporate responsiveness to society's needs by playing a more active role in overseeing managerial decisions.The purpose of this study is to partially fill a void in the literature by determining whether or not these expectations are justified, particularly in the service industry. Data were collected as part of a larger cross-national study of corporate social responsibility. A multivariate analysis of variance (MANOVA) of the results of a survey of 307 board members (198 outside and 109 inside directors) indicates that outside directors exhibit greater concern about the discretionary component of corporate responsibility and a weaker orientation toward economic performance. No significant differences between the two groups were observed with respect to the legal and ethical dimensions of corporate social responsibility. Some explanations as well as limited generalizations and implications are developed. 相似文献

Off-farm labor supply in Canada is modeled using separate off-farm labor participation and off-farm labor supply equations, which allows variables to affect participation and labor supply differently. The data used in this study are from Statistics Canada's Agriculture-Population Linkage Database, which links the Population Census for 1986 to a 20% sample from the Census of Agriculture. Results indicate that age, education and wages have large, significant and opposite effects on participation and supply, and that government efforts to stabilize and supplement farm incomes through rural employment programs may have less effect on labor allocation decisions than do the underlying demographic factors and regional and farm characteristics.
Nous modélisons id les disponibilités d'emploi extérieur (hors-ferme) pour les agriculteurs, utilisant des équations distinctes pour la participation aux emplois extérieurs et pour l'offre des emplois extérieurs, ce qui permet de laisser les variables influer différemment sur les deux éléments. Les donées utilisées proviennent de la base de données de Statistique Canada sur le couplage agriculture-population, laquelle relie le recensement de la population de 1986 à un échantillon de 20 % prélevé sur le recensement de l'agriculture. Les résultats font voir que l'âge, le niveau de scolarisation et les salaires ont de grands effets, significatifs mais opposés, sur l'utilisation et sur les disponibilites d'emplois extérieurs et que les initiatives de'État pour stabiliser et compléter le revenu agricole au moyen de programmes d'emploi rural auraient mains d'effets sur les décisions d'attribution des emplois que les facteurs sous-jacents relevant de la démographie et des caractéristiques particulières de chaque région et exploitation. 相似文献

The frequency of use and the marginal costs and marginal value products of mastitis control practices on somatic cell count (SCC) and milk yield are investigated. A survey of current management practices is combined with Dairy Herd Improvement production information to determine the relationships between milk yield, SCC, management practices, and production and producer characteristics under field conditions. The relationships are modeled and compared at the cow and herd level. A moment-generating approach is used in the herd model to determine which, if any, practices are risk reducing. The SCC for an individual cow is a better indicator of milk production lost due to mastitis than is a bulk tank SCC. Most recommended mastitis control practices are estimated to be economically beneficial, but some common practices are found not to be economical, and questions are raised about dry cow treatment. On a examiné la fréquence à laquelle on recourt aux pratiques de lutte contre la mammite, de même que les couts et les avantages marginaux de ces dernières en ce qui concerne la numération des cellues somatiques et le rendement laitier. On a combiné une enquête sur les pratiques zootechniques actuelles aux renseignements sur la production extraits du Programme d'amélioration des troupeaux laitiers en vue de déterminer les relations qui existent entre le rendement laitier, la numération des cellules somatiques, la conduite du troupeau ainsi que les caractéristiques associées à la production et aux producteurs, sur le terrain. On a ensuite modélisé ces relations et on les a compareées entre les animaux et les troupeaux. Pour le modèle touchant les troupeaux, on s'est servi d'une approche générant des moments, pour déterminer si une pratique quelconque diminuait les risques. La numération des cellules somatiques chez la vache est un meilleur indicateur du volume de lait perdu à la suite de la mammite que la numération des cellules somatiques dans la citerne. La plupart des méthodes de lutte contre la mammite recommendées offrent un avantage économique, mais certaines pratiques courantes ont l'effet contraire et on s'interroge sur l'utilité de traiter les vaches taries. 相似文献
