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

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

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

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

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

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

How should we evaluate research on counselling and the treatment of depression? A case study on how NICE’s draft 2018 guideline considered what counts as best evidence

Background: Health guidelines are developed to improve patient care by ensuring the most recent and “best available evidence” is used to guide treatment recommendations (NICE Guidance, 2017). NICE’s revised guideline development methodology acknowledges that evidence needed to answer one question (treatment efficacy) may be different from evidence needed to answer another (cost effectiveness, treatment acceptability to patients; NICE, 2014/2017). This review uses counselling in the treatment of depression as a case study, and interrogates the constructs of ‘best’ evidence and ‘best’ guideline methodologies. Method: The review comprises six sections: (1) the implications of diverse definitions of counselling in research; (2) research findings from meta-analyses and randomised controlled trials (RCTs); (3) limitations to trials-based evidence; (4) findings from large routine outcome datasets; (5) the inclusion of qualitative research that emphasises service-user voices; and (6) conclusions and recommendations. Results: Research from meta-analyses and RCTs reviewed in the draft 2018 NICE guideline is limited but positive in relation to the effectiveness of counselling in the treatment for depression. The weight of evidence suggests little, if any, advantage to CBT over counselling once bias and researcher allegiance are taken into account. A growing body of evidence from large NHS datasets also evidences that counselling is both effective and cost-effective when delivered in NHS settings. Conclusion: Recommendations in NICE’s own updated procedures suggest that sole reliance on RCTs and meta-analyses as best methodologies is no longer adequate. There is a need to include large standardised collected datasets from routine practice as well as the voice of patients via high-quality qualitative research

Competing Technologies in the Database Management Systems Market

The impact of research on policy: a case of qualifications reform

The relationship between research and policymaking has been discussed repeatedly. However, the debate tends to be in general, abstract terms or from a macro-economic perspective with any examples described in a fairly cursory way. Despite the inherent complexity of the research-policy interface, analyses tend to homogenize ‘research’ and ‘policy’ as coherent entities with discussions often focusing on products (research and policies) rather than on the relationships between producers (researchers and policy makers). Here we take one piece of research on qualifications that has influenced policy rhetoric over the last 5 years. We trace the career of the research from its production in the late 1990s in order to understand the conditions of its dormancy, reemergence and use over the ensuing years. The paper serves to document the case, which is important in its own right, but also proposes a typology of ways in which research gets adopted and adapted into policy
