Study analysing possible changes in the minimum rates and structures of excise duties on alcoholic beverages
The overarching objective of the study carried out by London Economics is to examine whether the current structures of alcohol taxation and the minimum rates laid down for the various categories are adequately supporting the effective functioning of the internal market, or whether distortions are caused and adaptations would be appropriate.European Union, taxation, excise duties
Definite Descriptions and the Gettier Example
This paper challenges the first Gettier counterexample to the tripartite account of knowledge. Noting that 'the man who will get the job' is a description and invoking Donnellan's distinction between their 'referential' and 'attributive' uses, I argue that Smith does not actually believe that the man who will get the job has ten coins in his pocket. Smith's ignorance about who will get the job shows that the belief cannot be understood referentially, his ignorance of the coins in his pocket shows that it cannot be understood attributively.
An explanation for why Smith appeared to have justified true belief is given by distinguishing between 'belief' and 'belief in truth'. Smith believes the sentence 'the man who will get the job has ten coins in his pocket' to be true (he mistakenly believes that Jones will get the job, of whom he knows that he has ten coins in his pocket) (hence his 'belief'), the sentence is true (hence 'truth'), and he has sufficient reason to assent to it (hence his 'justification'). But he does not believe the proposition expressed. Hence he does not know it eithe
Competing Technologies in the Database Management Systems Market
In this paper, we study the dynamics of the market for Database
Management Systems (DBMS), which is commonly assumed to possess network
effects and where there is still some viable competition in our study
period, 2000 – 2004. Specifically, we make use of a unique and
detailed dataset on several thousand UK firms to study individual
organizations’ incentives to adopt a particular technology. We
find that there are significant internal complement effects – in
other words, using an operating system and a DBMS from the same vendor
seems to confer some complementarities. We also find evidence for
complementarities between enterprise resource planning systems (ERP) and
DBMS and find that as ERP are frequently specific and customized, DBMS
are unlikely to be changed once they have been customized to an ERP. We
also find that organizations have an increasing tendency to use multiple
DBMS on one site, which contradicts the notion that different DBMS are
near-perfect substitutes
Market Dominance and Barriers To Competition in Financial Trading Venues
The Market in Financial Instruments Directive (MiFID) aims to increase
competition and to foster client protection in the European financial
market. Among other provisions, it abolishes the concentration rule and
challenges the market ower of existing trading venues. The directive
introduces venue competition in order to achieve better execution and
ultimately lower trading costs. In this paper I address the question of
whether fostering competition between alternative trading venues alone
may or not be able to impact actual competition in the market. I
consider two reasons for why it may not: direct network effects together
with increasing returns to scale, and post-trading constraints. In
particular, I (a) evaluate the actual degree of competition between
trading venues, (b) measure the impact of network effects on
competition, and lastly (c) assess the barriers to competition induced
to post-trading constraints. The results imply that financial
intermediaries tend to value liquidity more (than total fees) when
deciding where to route a given order for execution - implying that
being the incumbent venue translates into a competitive advantage.
Furthermore, eliminating the mentioned barriers to competition seems to
be associated with a significant decrease (of similar magnitude) in the
asymetry of the industry
The depression report: a new deal for depression and anxiety disorders.
Crippling depression and chronic anxiety are the biggest causes of misery in Britain today. They are the great submerged problem, which shame keeps out of sight. But if you mention them, you soon discover how many families are affected. According to the respected Psychiatric Morbidity Survey, one in six of us would be diagnosed as having depression or chronic anxiety disorder, which means that one family in three is affected. That is the bad news. The good news is that we now have evidence-based psychological therapies that can lift at least a half of those affected out of their depression or their chronic fear. These new therapies are not endless nor backwardlooking treatments. They are short, forward-looking treatments that enable people to challenge their negative thinking and build on the positive side of their personalities and situations. The most developed of these therapies is cognitive behaviour therapy (CBT). The official guidelines from the National Institute for Clinical Excellence (NICE) say these treatments should be available to all people with depression or anxiety disorders or schizophrenia, unless the problem is very mild or recent. But the NICE guidelines cannot be implemented because we do not have enough therapists. In most areas waiting lists for therapy are over nine months, or there is no waiting list at all because there are no therapists. So, if you go to the GP, all that can be provided is medication (plus at some surgeries a little counselling). But many people will not take medication, either because they dislike the side effects or because they want to control their own mood. The result is tragic. Only one in four of those who suffer from depression or chronic anxiety is receiving any kind of treatment. The rest continue to suffer, even though at least half of them could be cured at a cost of no more than £750. This is a waste of people’s lives. It is also costing a lot of money. For depression and anxiety make it difficult or impossible to work, and drive people onto Incapacity Benefits. We now have a million people on Incapacity Benefits because of mental illness – more than the total number of unemployed people receiving unemployment benefits. At one time unemployment was our biggest social problem, but we have done a lot to reduce it. So mental illness is now the biggest problem, and we know what to do about it. It is time to use that knowledge. 2 But can we afford the £750 it costs to treat someone? The money which the government spends will pay for itself. For someone on Incapacity Benefit costs us £750 a month in extra benefits and lost taxes. If the person works just a month more as a result of the treatment, the treatment pays for itself. So we have a massive problem – the biggest problem they have for one in three of our families. But we also have a solution that can improve the lives of millions of families, and cost the taxpayer nothing. We should implement the NICE guidelines; and most people with mental illness should be offered the choice of psychological therapy. Everyone who wants something done should write to their MP calling for action.
Co-opetition in standard-setting: the case of the Compact Disc
The success of the CD has (partly) been attributed to the ability of
Sony, Philips and Matsushita to cooperate in the run-up to the DAD
conference in 1981, where the technological standard was set. We model
the situation leading up to the conference in a simple game with
technological progress and the possibility of prelaunching a technology.
We identify players' trades between prelaunching(which ends
technological progress) and continued development (which involves the
risk of being pre-empted). Contrasting outcomes with complete and
incomplete information, we find that there appeared to be considerable
uncertainty about rivals' technological progress
Crowding Out or Complementarity in the Telecommunications Market?
There is a substantial number of cases where the a priori relationship
between products is not at all clear in the sense that although apparent
to be clear substitutes may turn out to be in fact complements, or
vice-versa. This paper aims to study the relationship between fixed and
mobile telephony in the United Kingdom and, in particular, address the
question if mobile communications crowded out fixed telephony or if, on
the other hand, the two types of communications are in fact complements.
We estimate a structural continuous-choice demand model following Pinkse
et al. (2002), Pinkse and Slade (2004), and Slade (2004) and we find
that at the current diffusion stage, fixed and mobile communications
appear to be complements. Given that the model is micro-founded, we also
address the question of how the evolution of the price differential
between the two types of communication may, respectively, affect the
welfare of consumers and firms. We find that the continuation of these
price trends have substantial welfare benefits for subscribers and at
the same time have no significant impact on the pro ts for firms.
Finally, we present some economic policy implications, especially about
the need to (de)regulate telecommunications provision

Search, Design, and Market Structure
The Internet has made consumer search much easier with consequences for
competition, industry structure and product offerings. We explore these
consequences in a rich but tractable model that allows for strategic
design choices. We find a polarized market structure, where some firms
choose designs aiming for broad-based audiences, while others target
narrow niches. Such an industry structure can arise even when all firms
and consumers are ex-ante identical. We perform comparative statics and
show the effect of a fall in search costs on the designs, market shares,
prices, and profits of different firms. In particular, a fall in search
costs, through the effect on product designs, can lead to higher
industry prices and profits. In characterizing sales distributions, our
analysis is related to discussions of how the Internet has led to the
prevalence of niche goods and the long tail and superstar phenomena
