an anti-trust regime for Britain

Britain needs a complete transformation of its policy towards monopoly. Robert Miller argues that freedom of entry is the vital ingredient of policy for regulating monopolies and public utilities.     

A panel data analysis of code-sharing,antitrust immunity,and open skies treaties in international aviation markets

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.

The Meaning of Applied Creativity in the Culinary Industry

ABSTRACT

The 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.     

Model selection in random effects models for directed graphs using approximated Bayes factors

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.     

The Role of Expectations in Explaining the Cross-Section of Stock Returns

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.
