This paper estimates the effects of code-sharing, antitrust immunity, and Open Skies treaties on prices, output, and capacity
using an eleven-year panel of U.S.-Europe data. Code-sharing and immunized alliances are found to have significantly lower
prices than does traditional interline (multi-carrier) service, but the effects are smaller in magnitude than those found
in previous results that rely on cross-sectional data. Statistical tests that prices for immunized alliance service are equal
to online (single carrier) service often cannot be rejected, providing additional evidence that immunity grants allow immunized
carriers to internalize a double marginalization problem. Estimated output effects, consistent with the price effects, show
that alliances are associated with large increases in passenger volumes. Lastly, estimates suggest that capacity expansions
associated with “Open Skies” treaties are due entirely to expansion by immunized carriers on routes between their hubs.

ABSTRACTThe purpose of this article is to present a study which explores the origin of applied creativity in the culinary industry, in Taiwan. A total of 36 Chinese and Western cuisine chefs from five-star hotels and top restaurants were interviewed to provide the data from this study. The findings indicate that the role of applied creativity in the culinary industry has played a key role in culinary change and evolution in Taiwan. Culinary creativity has its own distinct characteristics, such as time limitations and market acceptance, which are acquired through building blocks of professional skills and experience. The study contributes to understanding the role of applied creativity in the culinary industry. 相似文献

With the development of an MCMC algorithm, Bayesian model selection for the p 2 model for directed graphs has become possible. This paper presents an empirical exploration in using approximate Bayes factors for model selection. For a social network of Dutch secondary school pupils from different ethnic backgrounds it is investigated whether pupils report that they receive more emotional support from within their own ethnic group. Approximated Bayes factors seem to work, but considerable margins of error have to be reckoned with. 相似文献

We find highly significant results when the cross-section of market-adjusted stock returns is regressed against changes in analyst expectations this year about: (1) this year's earnings, (2) next year's earnings, (3) long-term earnings growth, and (4) noise (measured as the standard deviation of analyst forecasts). Surprisingly, changes in expectations about this year's earnings are not significant in a multiple regression with the other independent variables. Changes in expectations about next year's earnings are highly significant but with an impact that is much smaller than that of changes in expectations about the long-term growth in earnings. Changes in noise are also statistically significant and are negatively related to market-adjusted returns, an indication that the signal to noise ratio, rather than merely the signal, is what drives price adjustments to new information. 相似文献

We generalize Merton’s asset valuation approach to systems of multiple financial firms where cross‐ownership of equities and liabilities is present. The liabilities, which may include debts and derivatives, can be of differing seniority. We derive equations for the prices of equities and recovery claims under no‐arbitrage. An existence result and a uniqueness result are proven. Examples and an algorithm for the simultaneous calculation of all no‐arbitrage prices are provided. A result on capital structure irrelevance for groups of firms regarding externally held claims is discussed, as well as financial leverage and systemic risk caused by cross‐ownership. 相似文献

The influence of the media, whether print, celluloid or contemporary electronic, on life and career choices, particularly from a gender perspective is well documented. Indeed, the power of today’s e-media imagery has, arguably, a more ubiquitous influence on such decisions than was in the case for previous generations. However, both traditional print and more contemporary media influencers remain important and, therefore, gaining an understanding of their role in the representation of gendered work, both historically and in a modern context, is of considerable value. Working in the sky, whether as a pilot or member of the cabin crew, continues to hold a fascination and attraction for potential entrants that far exceeds the technical demands or financial rewards of the reality of such work. Perceived as ‘glamorous’ work since the early days of commercial flight in the 1930s, this tag has largely remained, despite major changes to the business and workplace environment in the intervening years. Commercial aviation is an area of work that has inspired a genre of influential romantic literature and numerous ‘real-life’ recollections alongside serious academic analysis. This paper charts the representation of, in particular, female flight attendant work from its ‘golden era’ through to the present context where the influence of the low-cost airline model has radically impacted upon the working environment within the sector. The discussion focuses on the broad ‘genre’ of airline-related employment literature, drawing on romantic, comic and biographical accounts alongside sources that address this theme from academic/research perspectives, in order to ask whether contemporary representation is any more a true reflection of this work than that during previous generations. In undertaking this analysis, this paper draws upon the role and career representation literature, particularly with respect to embodied and gendered work. 相似文献

To address agility in public administration, we have developed a knowledge acquisition infrastructure for legal knowledge, based on an implementation‐oriented conceptualization of the legal system. Our objective is to reframe legal knowledge as a knowledge source in a design‐oriented task ontology, building on insights from the CommonKADS methodology for intelligent system design. The main result is to make case law and legal expert knowledge of critical incidents in organizations, two diagnostic knowledge sources underutilized in modern management and engineering, more accessible as a resource for design of agile organizational structures and intelligent systems.

Unpredictable dividend growth by the dividend–price ratio is considered a ‘stylized fact’ in post war US data. Using long-term annual data from the US and three European countries, we revisit this stylized fact, and we also report results on return predictability. We make two main contributions. First, we document that for the US, results for long-horizon predictability are crucially dependent on whether returns and dividend growth are measured in nominal or real terms, and this difference is due to long-term inflation being strongly negatively predictable by the dividend–price ratio. The impact of inflation is to reinforce real return predictability and to reduce – or change direction of – real dividend growth predictability. This provides an explanation for the strong predictability of long-horizon real returns in the ‘right’ direction, and the strong predictability of long-horizon real dividend growth in the ‘wrong’ direction, that we see in US post war data. Second, we find that predictability patterns in three European stock markets are in many ways different from what characterize the US stock market. In particular, in Sweden and Denmark dividend growth is strongly predictable by the dividend–price ratio in the ‘right’ direction while returns are not predictable. The results for the UK are mixed. Our results are robust to a number of changes in the modeling framework. We discuss the results for dividend growth predictability in terms of the ‘dividend smoothing hypothesis’. 相似文献
