This paper describes the evolution of the mobile Internet in terms of three concepts: the startup problem, standard setting, and mental models. Products in which there is little or no value to the first users due to the existence of strong direct (e.g., telephone) or indirect (complementary products) network effects face a large startup problem. This paper divides the startup problem for the mobile Internet into two stages. Japanese and later other service providers solved the first startup problem with entertainment content that was supported by a micro-payment system (service providers collect and pass on content fees to content providers) and custom phones that displayed this content in a consistent manner. 相似文献

The assumption that economic actors behave in a boundedly self‐interested manner promises fruitful new insights for strategic management. A growing literature spanning multiple disciplines indicates most actors' selfish utility maximizing behaviors are bounded by norms of fairness. Rather than being purely self‐interested, people behave reciprocally by rewarding others whose actions they deem fair and willingly incurring costs to punish those they deem unfair. Economists show that employers who are perceived as distributionally fair by their employees generate comparatively more value due to the positively reciprocal behavior of those employees. The organizational justice literature distinguishes two additional types of fairness assessed by employees. Drawing from both these bodies of work, we employ stakeholder theory to propose how perceptions of fairness result in reciprocity (1) extending to all stakeholders of the firm and (2) affecting firm performance.

Most skills acquired through on-the-job training may be specificto an occupation and therefore transferable to some but notall firms. This paper explores the relationship between thesize of the local market for an occupation-specific skill andjob-training outcomes. The Stevens (1994) model of trainingpredicts that as market size increases, job turnover increasesand training becomes more general. I test these predictionsusing data on blue-collar workers and variation in market sizeacross US metropolitan areas. The empirical results supportthe theoretical predictions and the impacts are most relevantat low levels of market size. 相似文献

Internal carbon pricing is an innovative self-regulation mechanism where companies set their own carbon prices on business operations to mitigate climate risk and achieve sustainable development. While internal carbon pricing has gained popularity among multinational enterprises, its firm-level impact is underexplored. This research provides novel theoretical and empirical evidence on how the internal carbon price as a cost component can contribute to profitability growth. We construct a panel dataset of 132 multinational enterprises across Europe, North America, and Asia by tracking their use of internal carbon pricing from 2013 to 2017 based on their records at the Carbon Disclosure Project. To address endogeneity bias, we employ propensity score matching method on a fixed-effects model. Results indicate that using internal carbon pricing can increase return on assets by 1.1%. Firms with internal carbon prices are more likely to reduce cost of goods sold to improve return on assets. Our study suggests that internal carbon pricing as environmental self-regulation can generate profitability gains through cost reduction. The research also points out the potential of voluntary internal carbon pricing to complement command-and-control carbon pricing regulations. 相似文献

Telework has greatly increased in both popularity and use in recent years. The original impetus behind telework has shifted
over the years away from social responsibility as employers have come to realize the significant benefits they can reap from
a well-designed and implemented telework program. Despite the well-documented environmental, societal, employer and employee
benefits associated with telework, telework changes the nature of the employer–employee relationship and can have some detrimental
effects on an organizations if not implemented strategically. This paper explores the prevalence of and benefits and limitations
associated with telework and provides recommendations as to how to most effectively implement telework. 相似文献

A large part of the literature on provincial inequality in China has found it necessary to include regional dummies in the provincial growth regressions. A smaller but vocal part of the literature has emphasised the granting of preferential policies to explain the faster growth of the coastal provinces. We replace the regional dummies with a measure of the ability to participate in international trade (Geography), and a preferential policy index (Policy). We find that geography and policy had about equal influence on coastal growth (3 percentage points each). Geography affected growth with a much longer lag than policy, however. The policy index was highest for the metropolises (Beijing, Shanghai, and Tianjin) and lowest for the central and northwestern provinces. The preferential policies are to a large extent “deregulation policies” that enabled marketization and internationalization of the coastal economies and allowed them to become more like their East Asian neighbours (and competitors). The weak (statistically insignificant) support for conditional convergence is in line with the existence of institutions that retard the income convergence process generated by the movement of labor and capital and by the Stolper–Samuelson mechanism. The household registration system ties the peasants to the land, the monopoly state bank system favors borrowing by state enterprises, and local protectionism reduces inter-provincial trade. Clearly, these institutions need to be deregulated. An effective strategy to develop the western provinces must therefore encompass physical capital formation, human capital formation, and institutional capital formation. 相似文献

In this study, two non-homothetic translog stochastic meta-frontier cost functions—with and without local concavity imposed—are estimated using a nonlinear maximum likelihood estimation procedure to compare the cost efficiency of Alberta and Ontario dairy farms for the period 1984–96. The resulting cost efficiency estimates are not very sensitive to whether or not curvature is imposed. In contrast, the properties of the cost and input demand functions (e.g., elasticities) are sensitive to imposition of local concavity during estimation. The implication is that if an inappropriate model that does not satisfy the properties required by the economic theory is used, the estimated input demand functions may not be reliable. Average cost efficiency for the pooled sample, with local concavity imposed, is approximately 89%. This suggests some potential for improved performance in the sector. The results also suggest that Ontario dairy farms may be more cost efficient than Alberta dairy farms, but the statistical evidence is inconclusive. 相似文献

An exactly aggregable system of Gorman Engel curves for US food consumption is developed and implemented. Box-Cox transformations on prices and income nest functional form. The model nests rank up to rank three. The model is estimated by nonlinear three-stage least squares with annual time series data on 21 foods, 17 nutrients, age and race demographics, and the distribution of income for 1919–1941 and 1947–2000. Results are consistent with full rank three. Point estimates for the Box-Cox parameters on income and prices are 0.86 and 1.09, respectively, strongly rejecting zero and one in both cases. No statistical evidence of serial correlation, specification errors, or parameter instability is found. 相似文献

This study investigates the use of hedonic pricing to identify the value of relevant production and type traits for dairy bulls in Alberta. A hedonic pricing model is estimated that considers semen price as a function of individual production and longevily characteristics for a sample of Holstein bulls. The results suggest that the most important characteristics used by Alberta daity producers in valuing dairy bulls are milk volume, protein and fat content, general conformation, body capacity and the popularity of the bull. For a given set of such characteristics, the probability that the bull's semen may be in short supply does not significantly affect the value. This methodology may be used to establish a method of forecasting semen prices for newly proven bulls. The valuation procedure may be easily updated and adjusted as producers'breeding objectives change over time because of the changing economic environment. The results of this analysis suggest that hedonic pricing may be a better method of placing a value on production and type characteristics for dairy bulls than the Lifetime Profit Index currently being used by the Canadian dairy industry. 相似文献

It has been suggested that Mexican investors were the “front-runners” in the peso crisis of December 1994, turning pessimistic before international investors. Different expectations about their own economy, perhaps due to asymmetric information, prompted Mexican investors to be the first ones to leave the country. This paper investigates whether data from three Mexican country funds provide evidence that supports the “divergent expectations” hypothesis. We find that, right before the devaluation, Mexican fund Net Asset Values (mainly driven by Mexican investors) dropped first and/or faster than Mexican country fund prices (mainly driven by foreign investors). Moreover, we find that Mexican NAVs tend to Granger-cause the country fund prices. This suggests that causality, in some sense, flows from the Mexico City investor community to the Wall Street investor community. 相似文献
