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.

We test whether the amount and/or quality of financial statement information affects the financial structure of small and medium-sized enterprises (SMEs). Belgian SMEs are used, because there are important differences in disclosure and audit requirements among them. Consistent with the traditional view that asymmetric or incomplete information restricts access to external funds, our results indicate that both the amount and quality of financial statement information are positively related to SME leverage. In addition, we find that leverage is positively related to asset structure, growth (prospects) and median industry leverage, and negatively related to firm age and profitability. 相似文献
