Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- I think the lesson is that Malthus was wrong because he took the problem of limits outside of history, outside the history that women and men make in the modern world. So the issue is not that there is no scarcity — of course, capitalism is a system that is premised on induced scarcity. That’s why markets in the capitalist era function the way that they do. So I think the mistake of the left has been in a certain reluctance to deal with the problems of scarcity, or in some cases back into an embrace of a neo-Malthusian scarcity mentality in which there are these “natural limits” that are outside of how capitalism functions historically as an ecological regime.

Evaluating Asset-Pricing Models in International Financial Markets
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of three empirical studies on asset-prices in international financial markets. The purpose is three-fold. First, to evaluate whether good predictions of economic variables may be obtained by pooling information from a broad group of financial variables. Second, to formulate asset-pricing models from seven established stock markets. Third, to evaluate the asset-pricing models in the presence of short-sales.Chapter 2 applies a large data set, consisting of 167 monthly time series for the UK, both economic and financial, to simulate out-of-sample predictions of industrial production, inflation, three-month Treasury-Bills and other variables. Fifteen dynamic factor models that allow forecasting based on large panels of time series are considered. The performances of these factor models are then compared to the following competing models: a simple univariate autoregressive, a vector autoregressive, a leading indicator, and a non-expectational Phillips curve models. The results show that the dynamic factor models outperform the competing models in forecasting at 6-, 12-, and 24-month horizons. Two main findings are highlighted. First, the financial markets have a predictive power in terms of economic activity. Second, for some variables, the dynamic factor model appears to be more reliable than other competing models.In an attempt to analyze the equity premium puzzle and the risk-free rate puzzle, Chapter 3 compares different asset-pricing models within an international framework. To do so, it evaluates the performance of the following models: time separable-constant relative risk aversion, internal habit, external habit with externality, external habits which yield a constant risk-free rate, adaptive learning with constant gain, and state non-separability. The data are from seven industrialized countries, namely the United States, Canada, Japan, the United Kingdom, France, Denmark, and Sweden. Regarding empirical evidence, this thesis uses the Hansen-Jagannathan approaches to impose volatility restrictions on the asset-pricing models. The time-separable, adaptive learning and external habit models fail, and the evidence favors the internal habit persistence model. However, success is limited to some countries and to the equity premium puzzle rather than the risk-free rate puzzle. Finally, the state-non-separable specification consistently resolves the equity premium puzzle for all the countries.Chapter 4 analyzes the effect of market frictions on the equity premium puzzle. Indeed, in the standard asset-pricing model with time-separable preferences, the volatility of the intertemporal marginal rate of substitution is too low for plausible values of risk aversion to be consistent with consumption and asset return data. Following this, the Hansen-Jagannathan method is applied to evaluate the equity premium puzzle for the UK in two directions. First, the time-separable model, the internal and the external habit formation models and the state non-separable model are examined under the assumptions of both frictionless markets and market frictions. Second, a bootstrap experiment is conducted to show that these asset-pricing models violate the Hansen-Jagannathan bound in almost all the samples. Indeed, because of the changes in the sample means in consumption growth and asset returns, all the models appear to be weak under frictionless markets. By contrast, asset-pricing models with market frictions are much more successful in the bootstrap experiment.

Scientific Models : Red Atoms, White Lies and Black Boxes in a Yellow Book
- 2016
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- A zebrafish, the hull of a miniature ship, a mathematical equation and a food chain - what do these things have in common? They are examples of models used by scientists to isolate and study particular aspects of the world around us. This book begins by introducing the concept of a scientific model from an intuitive perspective, drawing parallels to mental models and artistic representations. It then recounts the history of modelling from the 16th century up until the present day. The iterative process of model building is described and discussed in the context of complex models with high predictive accuracy versus simpler models that provide more of a conceptual understanding. To illustrate the diversity of opinions within the scientific community, we also present the results of an interview study, in which ten scientists from different disciplines describe their views on modelling and how models feature in their work. Lastly, it includes a number of worked examples that span different modelling approaches and techniques. It provides a comprehensive introduction to scientific models and shows how models are constructed and used in modern science. It also addresses the approach to, and the culture surrounding modelling in different scientific disciplines. It serves as an inspiration for model building and also facilitates interdisciplinary collaborations by showing how models are used in different scientific fields. The book is aimed primarily at students in the sciences and engineering, as well as students at teacher training colleges but will also appeal to interested readers wanting to get an overview of scientific modelling in general and different modelling approaches in particular.

Organizational support for innovation in biosciences: Comparing high and low performers in Sweden and Croatia
- 2009
-
Ingår i: European Sociological Association, ESA 9th conference, 2-5 September, 2009, Lisbon.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- There is a need to better understand the organizational factors influencing innovative performance. This cross-cultural study examined organizational support factors in biotech R&D groups differing in innovative performance. The objective was to twofold; first to explore how organizing influences innovativeness in R&D, and, second to examine if R&D organizing is related to nations having a low and high innovation degree, respectively. Results supported that organizing R&D as well as national innovation performance are related. Crucial organizational issues found were how much organizations encouraged innovations, the degree of perceived autonomy and to what extent organizations could supply knowledge. Some of the implications of these results are introduced.

Möjligheter och hinder för en grön energiomställning : erfarenheter från andra regioner med lärdomar för Norrbotten
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport har tagits fram inom ramen för projektet Gröna energiinvesteringar som finan-sieras av Europeiska regionala utvecklingsfonden, Region Norrbotten, Länsstyrelsen i Norr-bottens län och Energimyndigheten. Projektet har drivits av Energikontor Norr i samverkan med Luleå tekniska universitet (Energiteknik, Nationalekonomi samt Entreprenörskap och Innovation) och Företagarna Norrbotten.Syftet med rapporten är att (a) öka förståelsen för de mervärden som kan uppstå regionalt och lokalt av en omställning av energisystemet och vilka hinder som kan finnas för en sådan omställning; samt att (b) identifiera olika former av strategier, styrmedel och affärsmodeller som kan bidra till realiserandet av nya hållbara energillösningar. Detta åstadkoms genom att konsultera och syntetisera relevanta erfarenheter från tidigare energiomställningsprocesser, samt genom att diskutera förutsättningarna för en sådan omställning i Norrbotten.Rapporten innehåller tre huvudsakliga delar. Den första delen är generell och baseras på erfarenheter och lärdomar från andra regioner och länder. Här diskuteras hinder för hållbara energiprojekt, med fokus på betydelsen av goda finansieringsmöjligheter, förutsättningar för etablerandet av ny teknologi samt hinder i form av sociala konstruktioner såsom stereotypa föreställningar om kön, etnicitet etc. En fallstudie av de hinder som kan försvåra ett ökat utnyttjande av industriell överskottsvärme belyser en rad faktorer som är viktiga att hantera i många former av samverkansprojekt på energiområdet. Den första delen av rapporten beskriver också hur hållbara energiprojekt kan bidra till regional ekonomisk utveckling, och identifierar vilka faktorer som påverkar hur stora dessa effekter kan bli. En viktig lärdom är att positiva spridningseffekter på den lokala ekonomin inte alltid sker automatiskt; olika åtgärder och strategier för att förstärka dessa effekter är ofta viktiga. Därför diskuteras även ett antal sådana strategier, t.ex. fondlösningar, lokalt ägande, gräsrotsfinansiering, samt olika strategier som syftar till att aktivt stärka de aktörsnätverk som behöver växa fram kring de nya projekten.Rapportens andra del vänder blicken mot Norrbotten, och diskuterar förutsättningarna för att en hållbar energiomställning med betydande mervärden för den ekonomiska utvecklingen kan åstadkommas i länet. Dessa förutsättningar beskrivs med utgångspunkt i de existerande strategier som finns för att stimulera regional ekonomisk tillväxt; en gemensam nämnare för dessa är att de pekar på möjligheterna att förena regionala tillväxtmål med en hållbar energiomställning. Här diskuteras även de regionala förutsättningarna för inkluderande, inte minst jämställd, innovation i länet.I rapportens tredje och avslutande del sammanfattas de viktigaste lärdomarna från rapporten. Här tydliggörs relevansen av de tidigare erfarenheterna och lärdomarna för det regionala sammanhanget, och vi diskuterar, med utgångspunkt i intervjuer av projektägare, erfarenheter rörande hinder, mervärden, strategier etc. från sju olika energiprojekt som följts och studerats i projektet Gröna energiinvesteringar. I ett avslutande kapitel lyfts ett antal viktiga lärdomar och rekommendationer för det fortsatta energiomställningsarbetet i länet fram.

Targeting the Environmental Sustainability of European Shipping: The Need for Innovation in Policy and Technology
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- At their Summit meeting in Gothenburg in June 2001, Europe’s heads of state and government reached agreement on a European strategy for sustainable development. The social and economic dimensions of the Lisbon strategy were complemented by an environmental dimension. Thus, the Gothenburg Summit represents a breakthrough for sustainable development in the European Union (EU). The University of Gothenburg and Chalmers University of Technology made a commitment to serve, through the joint Centre for Environment and Sustainability (GMV), as a hub for research and scientific follow up of the EU sustainable development strategy. In order to fulfill this commitment, the two universities have established a European Panel for Sustainable Development (EPSD), together with Lund University. In addition, individual members from other universities and research institutes contribute to the work of the Panel. The Centre for Environment and Sustainability (GMV) in Gothenburg is the lead organization in the EPSD. The first report produced by the Panel in 2004 was “From Here to Sustainability – Is the Lisbon/Gothenburg Agenda Delivering?” This was put forward as an independent contribution from academics to the mid-term review of the Lisbon strategy for growth, competitiveness and jobs. The second report “Make the Kok-report sustainable” was produced by the EPSD as a reflection on, and a response to, the mid-term review on the Lisbon strategy chaired by the former Prime Minister of the Netherlands, Wim Kok. The third report “Towards a Smart Growth Strategy for Sustainable Development” aimed to contribute to the re-launch of the EU sustainable development strategy. It contained a critical assessment of “A Platform for Action”, the proposal for an updated strategy put forward by the European Commission. The fourth report “TAKING CHILDREN SERIOUSLY – How the EU can Invest in Early Childhood Education for a Sustainable Future” presented research on children’s interest and ability to understand questions on the social, economic and environmental dimensions of sustainable development. The present report “Targeting the Environmental Sustainability of European Shipping: The Need for Innovation in Policy and Technology” has emerged from a background survey with the aim of mapping what is being done on sustainable shipping within the European Union. A wide scope of strategic EU policy sectors and documents, including existing directives, legislation and regulations on shipping were scrutinized to describe the actual knowledge framework. The background study defines areas where new research could contribute in closing knowledge gaps, and gives a compilation of directives and policy documents concerning sustainable shipping in a European perspective. Based on a definition of sustainable shipping that include all three pillars of sustainable development, the present report presents a holistic view and strategies for achieving a sustainable shipping industry. The report provides scientifically based knowledge of various aspects that affect sustainability at sea, such as particles, greenhouse gases, ship wrecks, ship recycling, and intermodality, as well as a comprehensive overview and updates on regulations. These various areas are presented as separate chapters and solid recommendations are presented on future actions (on EU and international level) to make the shipping industry in Europe a sustainable business. The main author of the report was Prof. Kevin Cullinane, Edinburgh Napier University, UK. The separate chapters in the report were written by Lars Barregård, University of Gothenburg, Erik Fridell, Hulda Winnes, IVL Swedish Environmental Research Institute (Particle emission from ships); Hannes Johnson 1 , Chalmers University of Technology (GHG Emissions and the Energy Efficiency Gap in Shipping); Peter Domini, Stena Metall (Ship Recycling: A Global Issue); Lars Barregård, University of Gothenburg (The Health Risks Associated with the Ship Breaking Industry); Ida-Maja Hassellöv, Chalmers University of Technology (Potentially Polluting Shipwrecks); Abhinayan Basu Bal, University of Gothenburg (Sustainable Intermodal Transport with Short Sea Shipping in the EU); A number of researchers and knowledgeable persons have constituted a reference group and further contributed to the report: Katarina Gårdfeldt, Maria Svane, Dan Strömberg, and Jonas Norrman, GMV, Gothenburg; Karin Andersson, Björn Södahl, Josefin Borg, and Oliver Lindqvist, Chalmers University of Technology; Lars Göran Malmberg, Johan Boman, Johan Woxenius, and Mattias Hallquist, University of Gothenburg, Christer Forsgren, Stena Metall; Anders Carlberg, Vgregion; Carl Carlsson, Swedish Shipowners Association, and Axel Wenblad, Former GD National Board of Fisheries. Dan Strömberg, and Maria Svane, University of Gothenburg, have been invaluable during the course of the project and as editors of the publication. The report has been endorsed by the EPSD.

Essays on Spatial Economies and Organization
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis concerns both static and dynamic modeling in a spatial computable general equilibrium setting. First, we have applied a static framework for the assessment of economic impacts of the Öresund bridge. Secondly, we make an attempt to enhance the static framework through the introduction of economic dynamics. Third, we introduce the STRAGO model, incorporating monopolistic competition, dynamics and additive transport costs. STRAGO is applied to the analysis of effects from a kilometer tax on freight. The last paper presents a framework for studying the division, or fragmentation of production. This framework uses the standard theory of monopolistic competition, with a production chain extension, through a recursive view of markets. The optimal level of fragmentation in such industries is studied.

Mellan genialitet och galenskap: Recension av Benjamin Labatuts roman "MANIAC"
- 2023
-
Ingår i: Tidskriften Alba. - 1403-5448.
-
Recension (övrigt vetenskapligt/konstnärligt)abstract
- John von Neumann var ett för de allra flesta okänt ungerskt underbarn av judisk härkomst som sedermera flydde undan nazisterna till USA, där han dog 1957. Han var ett matematiskt universalgeni som gav viktiga, för att inte säga avgörande, bidrag till fysikens, biologins, data- och samhällsvetenskapens och meteorologins (och därmed klimatvetenskapens) utveckling under 1900-talet. Vid sidan av den mer allmänt kände Alan Turing föranstaltade han det som vi idag lär känna som A.I. och teoretiserade tidigt om hur man kunde tänka på maskiner som livsformer analogt med biologiska – en idé som idag ingår både i evolutionsbiologiska verktygslådor liksom i visioner och mardrömsscenarier om en teknologisk singularitet bortom vilken generella A.I. dominerar och, i värsta fall, tränger ut människoarten. Det är denne märkliga och skrämmande person Benjamín Labatuts välskrivna roman sätter i centrum för en berättelse om gränslandet mellan genialitet och galenskap, vetenskap och teknik från förra sekelskiftet till nu, logikseminariernas tankelekar och konkret global politisk utveckling på liv och död. Romanen är pärlande klart översatt av Anna Petronella Foultier. Man behöver nog ha ett visst intresse för vetenskap, teknik och/eller global politik för att uppskatta den fullt ut, men mycket sådant förklaras under hand på ett skenbart enkelt vis, så jättestora kunskaper behövs inte.
