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.

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

The social spotlight seems to be refocusing to the scale of local community at a time when globalisation of the economy is threatening the authority of nation-states. Certain small communities are in peril of falling out of the global economy while losing local customs to a globalised culture. Globally beleaguered nation-states are being squeezed in a two-pronged grip: from the growing weight of global capital and from local communities rising to global pressures by demanding local solutions. National authority is also being bypassed as new global communities of interest form on the Internet, expanding the meaning of the term community. But, is community more than common interest—a celebration of difference, negotiating symbiosis among diversity of ethnicity, lifestyle and aspirations for the future? This paper explores five scenarios of tomorrow’s communities. One scenario is a nostalgic return to the romantic notion of the white-picket fence. Then there is the drop-out feral community. In another future the fence becomes a fortress wall, or a ring of barbed wire. Yet another is a virtual community beyond place, where people sharing a common interest live in cyber-reality. The viable community is one for the long haul. To be viable in a global world it must make local-global links to create synergies by sharing resources and inspirations throughout a diverse, planetary society. Viable, local-global network communities of tomorrow set a global example for creativity by honouring difference and open exchange. They take responsibility for their own futures.Two powerful images from recent events remain with me, in juxtaposition. After considering the American attacks on Afghanistan, a well-experienced teacher feels isolated at the periphery, and powerless. In addition, she watches, in “quiet despair”, one of her pupils “virtually going crazy” before her eyes. She shares these words with me:
“Neither he nor I, it seems, have anywhere to run except to the graciousness and the care of the other children, that as classroom leader I’m tying daily to coalesce, in order to put a cocoon of community around him. Bit like the planet!”
“We all work to keep our very bright and fairly disturbed ADHD-labelled1 learner connected to us in genuine relationship. That’s the foundation of authentic learning support. I’m not operating a medical model!”Our leaders and the babbling mass media ignore this, the first image, and many similar to it.By contrast, the second image gets constant exposure. It gets instant recall from most TV viewers. It is the scramble of screen jockeys, on what is left of Wall Street, playing the casino economy, in a frenzy of greed. Curiously the main media focus emphasizes images that represent the world at the global scale. They largely ignore images of life at the scale of community.Why is this? Why does the second image of the so-called finance community, where the focus is the dollar, override the more basic image of a hometown community where the focus is human life-support? Are the media reflecting our true priorities, and have we got it wrong? Is money more important than community? 相似文献

The intrinsic value approach amortizes over the life of the option, the difference between the stock price on the date of the grant and the exercise price of the option. The fair market value approach amortizes over the life of the option, the market value of stock options on the date of the grant. These approaches do not reflect the changes in the option–based compensation cost after the grant date. This paper proposes an economic cost approach that not only adjusts for the changes in the value of the options during its life but also records the issuance of the stock at fair market value on the exercise date. 相似文献

The demand for and supply of analysts’ opinions in this model yield an equilibrium that demonstrates how the information content
of the opinions reacts to changes in exogenous parameters. The model also shows how changes in the parameters make analysts’
opinions more or less dispersed; for example, a decline in investor risk aversion, a decrease in market volatility, and an
increase in information costs can lead to analysts’ opinions becoming more similar. Recognizing how exogenous factors can
affect the supply and demand of analysts’ opinions gives additional insights into questions concerning what may appear to
be herd behavior by analysts and also the relationship between forecast dispersion and information content. (JEL: G29, C71) 相似文献
