Summary Competition authorities are increasingly measuring the effects of their enforcement actions, seeking a robust justification
for the proliferation of competition policy. We highlight the importance of identifying the right counterfactual against which
to measure effects, and set out the relevant categories of costs and benefits. We then explore how a balance can be struck
between the benefits and inherent limitations of these measurement exercises. Relatively crude analyses of cartel action benefits
can be sufficient to achieve public legitimacy for competition policy. Assessing the effects of merger and conduct inquiries
is often ambiguous, but could be used to improve decision-making processes.

Determinants of Current Account Imbalances in 16 OECD Countries: An Out-Of-Sample Perspective 总被引:1,自引:0,他引:1
We employ panel data as well as country-specific models to uncover empirically the determinants of current account imbalances.
We find evidence of slope heterogeneity likely rendering the fixed-effect estimator inconsistent. Mean group estimation is
followed to overcome the latter difficulty. Both estimation techniques are evaluated by means of in- and out-of-sample criteria.
The mean group estimator outperforms the fixed-effect approach and, moreover, only three economic variables are found to impact
on the current account balance significantly. These are the government budget balance, the domestic output gap and the changes
of the terms of trade. We finally propose a parsimonious dynamic model of the current account, including only these variables
and illustrate that it has similar predictive accuracy as country-specific benchmark models.

A survey conducted in Mississippi, Texas, Indiana, and Nebraska elicited producers' preferences for various farm policy changes. This permitted examination of the diversity of preferences that single-state studies have not allowed. Five policy choices, including deficiency payments, loan programs, crop insurance, export programs, and disaster payments were examined. Logit model results predicting producer preferences for each of the five dichotomous policy choices are reported. Explanatory variables based on expected utility theory such as risk aversion, price and yield variability, and price–yield correlation are significant in various models. 相似文献

The role of tourism is of vital economic importance, particularly for small countries with a privileged geographical location and favourable weather conditions. This paper examines the importance of tourism as a conditioning factor for higher regional growth in Portugal by employing the conditional convergence hypothesis of Barro and Sala-i-Martin, associated with the endogenous growth theory. The panel data estimation approach provides evidence of the positive impact of tourism (through the accommodation capacity) on the growth in per-capita income among the Portuguese regions, increasing the rate of convergence. Therefore, tourism can be considered as an alternative source for stimulating higher regional growth in Portugal, if the supply characteristics of this sector are improved. 相似文献

Zusammenfassung Die Bildung von Forschungshypothesen ist zwar immer ein kreativer, sollte aber gleichzeitig kein unsystematischer
Prozess sein. Im vorliegenden Artikel liegt der Fokus auf der Methodenunterstützung des Entdeckungszusammenhangs.
Die Methode der Grounded Theory bietet einen Bezugsrahmen für qualitative empirische Studien, mit dem
Theorien entwickelt werden, die aus dem Textmaterial zu begründen sind. Eine Literaturanalyse verdeutlicht,
dass das Potenzial dieser Methode bisher in der Controlling- und Rechnungswesenforschung weitgehend ungenutzt
bleibt. Anhand einer Diskussion empirischer Studien, welche auf die Methode zurückgreifen, werden
Anwendungsm?glichkeiten der Grounded Theory für diese Disziplinen aufgezeigt.
Summary Creating research hypotheses is always a creative but not necessarily an unsystematic process. In our study we introduce a method supporting the logic of discovery. The grounded theory approach provides a framework for a systematic development of theories emerging from empirical data. A literature review stresses that the potential of the method so far is unused in accounting research. The grounded theory approach is introduced to support empirical work within this research field. Options for an application of the method in accounting research are shown by the means of a discussion of empirical studies. Furthermore the reader gets hints for reference studies.相似文献
