Innovation and horizontal mergers in a vertically related industry

This paper analyzes the effects of horizontal mergers on innovation and consumer welfare in a vertically related industry context, in which downstream firms compete for customers with a differentiated final good and can undertake R&D activities to reduce their unit costs. Upstream and downstream horizontal mergers can take place. The results suggest that competition authorities aiming to promote innovation and consumer welfare should treat upstream and downstream mergers differently, since horizontal mergers between upstream firms are detrimental to innovation and consumer welfare. By contrast, policy makers should evaluate the market characteristics under downstream integration. We show that downstream horizontal mergers can be both innovation and consumer welfare enhancing in the short run, when the markets are sufficiently small. Keywords: Horizontal Mergers. Innovation.

Ownership Effects on Unrelated Diversification: An Institutions' Perspective

Purpose To show that differences in the extent to which firms engage in unrelated diversification can be attributed to differences in ownership structure. Methodology/approach We draw on longitudinal data and use a panel analysis specification to test our hypotheses. Findings We find that unrelated diversification destroys value; pressure-sensitive Anglo-American owners in a firm’s equity reduce unrelated diversification, whereas pressure-resistant domestic owners increase unrelated diversification; the greater the firm’s free cash flow, the greater the negative effect of pressure-sensitive Anglo-American owners on unrelated diversification. Research limitations/implications We contribute to corporate governance and strategy research by bringing in owners’ institutional origin as a shaper of owner preferences in particular with regards to unrelated diversification. Future research may expand our investigation to more than one home institutional context, and theorize on institutional origin effects beyond the dichotomy between Anglo-American and non-Anglo-American (not oriented toward shareholder value maximization) owners. Practical implications Policy makers, financial analysts, owners, and managers may want to reflect about the implications of ownership structure, as well as promoting or joining corporations with particular ownership configurations. Social implications A shareholder value-destroying strategy, such as unrelated diversification has adverse consequences for society at large, in terms of opportunity costs, that is, resources could be allocated to value-creating activities instead. Promoting an ownership configuration that creates value should contribute to social welfare. Originality/value Owners may not be exclusively driven by shareholder value maximization, but can be influenced by normative beliefs (biases) stemming from the institutional context they originate from.

Cost-effectiveness of Tenofovir / Emtricitabine / Efavirenz versus Zidovudine / Lamivudine / Efavirenz as fist-line regimens for the treatment of HIV-infected patients in low-income settings

The Highly Active Antiretroviral Therapy (HAART) is the combination of at least three antiretroviral compounds. The combination purpose is to reduce the likelihood of drug resistance. However in the long-term the resistance to the first-line combination occurs and leads to treatment failure. Thus, a second-line and even a third-line regimen are recommended in the long run. [...] [P. 5] The two treatment alternatives under comparison: Tenofovir (300 mg) CO-formulated with Emtricitabine (200 mg) and Efavirenz (600 mg) currently known under the brand name Atripla (R) was introduced in July 2006 in the United States market. The excellent safety profile and ease of use make this combination a perfect first-line regimen in low-income settings. Therefore, this treatment option was recommended in WHO 2006 reviewed guidelines. Unfortunately, Tenofovir and Emtricitabine compounds are still costly and not yet widely available. For a matter of simplification this regimen is referred in this report as "the recent" therapy. Initially, we had in mind to consider the most frequently used first-line regimen in low-income countries (Stavudine / Larnivudme / Nevirapine) as a comparator for this economic evaluation. Unfortunately, according to the literature review results (see Annex 3); there was no data available comparing head to head the effectiveness of this regimen with the recent one. Instead, we selected a less frequently but commonly used first-line regimen in low-income countries as a comparator: Zidovudine, Lamivudine, Efavirenz. This combination has extensive experience in durability, safety and toxicity and seems to be an optimal choice for a first-line regimen according to the clinical trial group 384 team. Furthermore, Zidovudine, one of the compounds of this combination is now recommended as one of the preferred NNRTI [Non Nucleoside Reverse Transcriptase Inhibitors] options to be considered by countries instead of Stavudine (the most used NNRTI in limited-income countries). As this combination has been included in the WHO guidelines as a first-line therapy since 2003 when WHO launched the "3 by 5" scaling-up initiative, this combination of drugs is referred in this report as the "old" therapy. Objectives: The primary objective of this economic evaluation is to compare the two first-line HAARTs introduced above, in a low-income setting context. Both of these combinations are recommended by the 2006 WHO guidelines as potential first-line regimens. The secondary objective is to provide a simplified and comprehensible cost-effectiveness modeling tool in order to help policy makers, in resource-limited settings, make decisions about which first-line HAART to fund using the scarce resources available.

The First International Workshop on Warning Criteria for Active Slides: technical issues, problems and solutions for managing early warning systems

Early warning systems (EWSs) rely on the capacity to forecast a dangerous event with a certain amount of advance by defining warning criteria on which the safety of the population will depend. Monitoring of landslides is facilitated by new technologies, decreasing prices and easier data processing. At the same time, predicting the onset of a rapid failure or the sudden transition from slow to rapid failure and subsequent collapse, and its consequences is challenging for scientists that must deal with uncertainties and have limited tools to do so. Furthermore, EWS and warning criteria are becoming more and more a subject of concern between technical experts, researchers, stakeholders and decision makers responsible for the activation, enforcement and approval of civil protection actions. EWSs imply also a sharing of responsibilities which is often averted by technical staff, managers of technical offices and governing institutions. We organized the First International Workshop on Warning Criteria for Active Slides (IWWCAS) to promote sharing and networking among members from specialized institutions and relevant experts of EWS. In this paper, we summarize the event to stimulate discussion and collaboration between organizations dealing with the complex task of managing hazard and risk related to active slides.

Vulnerability of stream biota to climate change in mediterranean climate regions: a synthesis of ecological responses and conservation challenges

Freshwater species worldwide are experiencing dramatic declines partly attributable to ongoing climate change. It is expected that the future effects of climate change could be particularly severe in mediterranean climate (med-) regions, which host many endemic species already under great stress from the high level of human development. In this article, we review the climate and climate-induced changes in streams of med-regions and the responses of stream biota, focusing on both observed and anticipated ecological responses. We also discuss current knowledge gaps and conservation challenges. Expected climate alterations have already been observed in the last decades, and include: increased annual average air temperatures; decreased annual average precipitation; hydrologic alterations; and an increase in frequency, intensity and duration of extreme events, such as floods, droughts and fires. Recent observations, which are concordant with forecasts built, show stream biota of med-regions when facing climate changes tend to be displaced towards higher elevations and upper latitudes, communities tend to change their composition and homogenize, while some life-history traits seem to provide biota with resilience and resistance to adapt to the new conditions (as being short-lived, small, and resistant to low streamflow and desiccation). Nevertheless, such responses may be insufficient to cope with current and future environmental changes. Accurate forecasts of biotic changes and possible adaptations are difficult to obtain in med-regions mainly because of the difficulty of distinguishing disturbances due to natural variability from the effects of climate change, particularly regarding hydrology. Long-term studies are needed to disentangle such variability and improve knowledge regarding the ecological responses and the detection of early warning signals to climate change. Investments should focus on taxa beyond fish and macroinvertebrates, and in covering the less studied regions of Chile and South Africa. Scientists, policy makers and water managers must be involved in the climate change dialogue because the freshwater conservation concerns are huge.

The use of future-oriented knowledge in regional innovation processes: Research on knowledge generation, transfer and conversion

The importance of the regional level in research has risen in the last few decades and a vast literature in the fields of, for instance, evolutionary and institutional economics, network theories, innovations and learning systems, as well as sociology, has focused on regional level questions. Recently the policy makers and regional actors have also began to pay increasing attention to the knowledge economy and its needs, in general, and the connectivity and support structures of regional clusters in particular. Nowadays knowledge is generally considered as the most important source of competitive advantage, but even the most specialised forms of knowledge are becoming a short-lived resource for example due to the accelerating pace of technological change. This emphasizes the need of foresight activities in national, regional and organizational levels and the integration of foresight and innovation activities. In regional setting this development sets great challenges especially in those regions having no university and thus usually very limited resources for research activities. Also the research problem of this dissertation is related to the need to better incorporate the information produced by foresight process to facilitate and to be used in regional practice-based innovation processes. This dissertation is a constructive case study the case being Lahti region and a network facilitating innovation policy adopted in that region. Dissertation consists of a summary and five articles and during the research process a construct or a conceptual model for solving this real life problem has been developed. It is also being implemented as part of the network facilitating innovation policy in the Lahti region.

Liiketoimintatiedon merkitys ja -hallinta yritysjohdon päätöksenteon tukena, case: kunnallinen energiayhtiö

Yritykset toimivat yhä enemmän dynaamisessa ja jatkuvasti muuttuvassa yritysympäristössä, joka asettaa erittäin suuria haasteita yritysjohdolle, tilanteet ovat yhä vaikeammin ennustettavissa ja päätöksenteosta on tullut entistä haasteellisempaa. Nykypäivän kilpailuympäristössä yritykset hakevat kilpailuetua tiedon avulla. Yritysten käytettävissä olevan tiedon määrä on jatkuvassa kasvussa ja oleellisen tiedon erottaminen epäoleellisesta on yhä vaativampaa. Yritystä on vaikea johtaa tehokkaasti, jos yrityksessä ei ole käytössä oikeanlaista tietoa oikeaan aikaan oikeilla ihmisillä. Työn tavoitteena oli tutkia sitä, että millaista informaatiota ja tietoa tulisi kohdeyrityksen johdolla olla nykyhetkellä yrityksen toiminnan ohjaamiseen, suunnitteluun ja päätöksenteon tueksi. Tutkimusta on tarkasteltu johdon laskentatoimen näkökulmasta ja työssä on keskitytty teorian ja empirian pohjalta kohdeyrityksen johdon strategisen päätöksenteon pohjalla olevan oleellisen liiketoimintatiedon kartoittamiseen ja sen hallintaan. Yritysten toimiessa informaatioähky yhteiskunnassa, liiketoimintatiedon hallinnalla voidaan saavuttaa merkittävää kilpailuetua. Liiketoimintatiedon hallinta on käytäntöjä, toimintoja ja prosesseja, joilla yrityksen tärkeää liiketoimintatietoa hankitaan, jalostetaan ja jaetaan sekä liiketoiminnan johtamista että päätöksentekoa varten. Liiketoimintatiedon hallinnan yhtenä tietolähteenä toimii yrityksen sisäinen tietopääoma, joka tehokkaasti yhdisteltynä yrityksen ulkopuoliseen tietoon mahdollistaa yritysjohdolle laadukkaamman ja kokonaisvaltaisemman tiedon saamisen päätöksenteon tueksi. Tutkituissa yrityksissä käytettiin päätöksenteon tukena erittäin paljon taloudellisia tunnuslukuja, ns. kovia mittareita. Hiljaisia ja heikkoja signaaleja pidettiin myös tärkeinä, mutta ongelmana koettiin niiden havaitseminen, keruu ja raportointi. Yrityksen sisältä ja yrityksen ulkopuolelta raportoitavat tiedot tulisi jatkossa kohdistua enemmän tulevaisuuteen kuin menneisyyteen.

Verkostot kuntien kehittämisessä

Tutkimuksen tarkoituksena on selvittää verkostojen merkitystä uusien ideoiden tuojana kuntajohtamisessa kuntajohtajan näkökulmasta katsottuna ja osallistua liiketaloudelliseen keskusteluun kuntajohtamisen kehittämiseksi. Tutkimuksen tavoitteena on kuvata ja ymmärtää kuntajohtajan verkostoja ja niiden merkitystä kuntien kehittämisessä. Tutkimus on luonteeltaan laadullinen tutkimus, jonka aineisto on kerätty haastattelemalla neljää kuntajohtajaa. Tutkimustulokset osoittavat, että kuntajohtajat toimivat aktiivisesti kunnan ulkopuolisissa verkostoissa pyrkien löytämään ideoita ja ratkaisuja kuntien uudistamiseen. Kuntien sisäisten verkostojen, henkilöstön ja poliittisten päättäjien, hyödyntämistä voidaan parantaa yhteisellä strategiatyöllä ja sosiaalista vuorovaikutusta sekä johtamisjärjestelmiä kehittämällä. Myös asiakkaiden osallistumista uusien sosiaalisten innovaatioiden kehittämiseen tulisi lisätä. Tutkimuksessa käytettiin viitekehyksenä Todorova ja Durisinin (2008) absorptiivisen kapasiteetin mallia, johon mallin soveltamisen pohjalta esitetään kehittämisajatuksia.

Globaalien toimijoiden kilpailuseuranta-analyysi paperipigmenttialalla

Työssä tarkastellaan paperipigmenttialaa ja globaaleja paperipigmenttitoimittajia. Työn tarkoituksena on selvittää merkittävät paperipigmenttivalmistajat ja heidän roolinsa kyseisellä toimialalla. Tärkeimpiä paperipigmenttejä ovat kalsiumkarbonaattipitoiset pigmentit, kaoliini ja talkki. Paperipigmenttien toimittajia on ympäri maailmaa. Toimialan kilpailu on kasvanut viimeisen kymmenen vuoden aikana ja globaalien toimittajien osuus on ollut merkittävää kilpailun kehityksessä. Paperiteollisuus on suurin paperimineraalien kuluttaja. Mineraalipohjaisilla paperipigmenteillä voidaan parantaa paperin laadullisia ominaisuuksia sekä vähentää tuotantokustannuksia. Paperipigmenttien kysyntä on riippuvainen paperiteollisuuden tarpeista. Paperipigmenttialan kehitys on vahvasti sidoksissa paperiteollisuuden rakenteen muutoksiin. Paperipigmenttialan sisäisessä kilpailussa globaalit yritykset ovat suunnan näyttäjiä. Kilpailua käydään sekä paikallisella että kansainvälisellä tasolla. Globaaleilla yrityksillä on suuremmat voimavarat vastata paperiteollisuuden tuomiin haasteisiin. Kilpailua käydään niin asiakkaista kuin raaka-ainelähteistä. Yrityksiltä vaaditaan entistä enemmän tiettyjä ominaisuuksia, kuten raaka-aineita, rahoituksellista voimaa ja osaamista pärjätäkseen globaalissa toimintaympäristössä.

Aaltopahvituotteen kustannusrakenne: tietolähteidenmallintaminen ja dokumentointi

Tämän diplomityön tarkoituksena on muodostaa yleinen kustannusrakenneviitekehys aaltopahvituotteelle. Lisäksi työ määrittelee ja dokumentoi kustannusrakenteeseen liittyvät tärkeimmät tietolähteet. Diplomityö on tehty erään aaltopahviteollisuusyrityksen toimeksiantona ja liittyy kohdeyrityksessä tehtävään toiminnanohjausjärjestelmän uusimisprojektiin. Teoriaosassa muodostettua kustannusrakenneviitekehystä sovelletaan empiriaosassa työn kohdeyritykseen. Edellä mainittua sovellusta testataan vertailemalla vanhaa ja uutta laskentajärjestelmää toisiinsa kolmen erilaisen tuotteen avulla. Empirian kautta syntyneet työn tulokset osoittavat, että kustannusrakennetta määriteltäessä tärkeintä on huomioida päätöksenteon tietotarpeet ja turvata niiden täyttäminen. Aaltopahvituotteen yleisen kustannusrakenteen määrittäminen osoittautuu myös haastavaksi, koska aaltopahviteollisuusyritysten erilaiset ydinosaamisalueet vaikuttavat voimakkaasti siihen millainen määrittelystä lopulta tulee.

Public and Private Production in a Mixed Delivery System: Regulation, Competition and Costs

Academics and policy makers are increasingly shifting the debate concerning the best form of public service provision beyond the traditional dilemma between pure public and pure private delivery modes, because, among other reasons, there is a growing body of evidence that casts doubt on the existence of systematic cost savings from privatization, while any competition seems to be eroded over time. In this paper we compare the relative merits of public and private delivery within a mixed delivery system. We study the role played by ownership, transaction costs, and competition on local public service delivery within the same jurisdiction. Using a stochastic cost frontier, we analyze the public-private urban bus system in the Barcelona Metropolitan Area. Our results suggest that private firms tendering the service have higher delivery costs than those incurred by the public firm, especially when transaction costs are taken into account. Tenders, therefore, do not help to reduce delivery costs. Our results suggest that under a mixed delivery scheme, which permits the co-existence of public and private production, the metropolitan government and the regulator can use private delivery to contain costs in the public firm and, at the same time, benefit from the greater flexibility of private firms for dealing with events not provided for under contract.

The Determinants of Entrepreneurship in Developing Countries

We address the question of what determines entrepreneurship in developing countries. In particular, because of the influence that this may have on the design of entrepreneurship policies, our main concern is whether the determinants of entrepreneurship are the same and/or have the same impact in developed and developing countries. To this end, we discuss the arguments put forward in the literature in support of the existence of differences in the determinants of entrepreneurship between developed and developing countries. We also analyse the results found in empirical studies on the determinants of formal firm entry (following the World Bank, our proxy of entrepreneurship) in developing countries and compare these results with those typically found in developed countries. Our main conclusion is that policy makers in developing economies should be careful when using evidence from developed countries to design entrepreneurship-promoting policies. Key words: entrepreneurship, developing countries. JEL: O1; O12; L26; M13

Shaping urban traffic patterns through congestion charging : What factors drive success or failure?

Congestion costs are emerging as one of the most important challenges faced by metropolitan planners and transport authorities in first world economies. In US these costs were as high as 78 million dollars in 2005 and are growing due to fast increases in travel delays. In order to solve the current and severe levels of congestion the US department of transportation have recently started a program to initiate congestion pricing in five metropolitan areas. In this context it is important to determine those factors helping its implementation and success, but also the problems or difficulties associated with charging projects. In this article we analyze worldwide experiences with urban road charging in order to extract interesting and helpful lessons for policy makers engaged in congestion pricing projects and for those interested in the introduction of traffic management tools to regulate the entrance to big cities.

The institutional vs. the academic definition of the quality of work life. What is the focus of the European Commission?

In recent years, we have seen how the quality of work life has been focused and defined by the European Commission (EC). In our study we compare the EC definition with the academic one and try to see how close they are. We also analyse the possibility of applying the institutional definition to the Spanish case through the development of specific indicators. Our main conclusions are that QWL is increasingly important for policy makers. In addition, it is essential to have objective indicators and to conduct surveys in order to reliably measure QWL.

Searching for consensus in ahp-group decision making. A bayesian perspective

This paper sets out to identify the initial positions of the different decisionmakers who intervene in a group decision making process with a reducednumber of actors, and to establish possible consensus paths between theseactors. As a methodological support, it employs one of the most widely-knownmulticriteria decision techniques, namely, the Analytic Hierarchy Process(AHP). Assuming that the judgements elicited by the decision makers follow theso-called multiplicative model (Crawford and Williams, 1985; Altuzarra et al.,1997; Laininen and Hämäläinen, 2003) with log-normal errors and unknownvariance, a Bayesian approach is used in the estimation of the relative prioritiesof the alternatives being compared. These priorities, estimated by way of themedian of the posterior distribution and normalised in a distributive manner(priorities add up to one), are a clear example of compositional data that will beused in the search for consensus between the actors involved in the resolution ofthe problem through the use of Multidimensional Scaling tools
