Economist Thomas Malthus believed that inequality within societies are inescapable (Piketty, 2014). Iceland is no exception to the general structure of wealth inequality within advanced economies (AEs). In this thesis the distribution of wealth between 1997-2017 in Iceland is analyzed focusing on what are the main drivers of wealth inequality and how has the distribution of wealth changed during these twenty years especially following the 2008 financial crisis. To analyze the development of wealth distribution a principal component analysis is performed as well as comparing net wealth between percentiles. In Iceland, between 1997-2017 the top 1% wealthiest individuals of the population owned more than half of total net wealth and in 2010 that percentage increased to over 70% of total net wealth. Wealth inequality reached its high point in 2010, then decreased yearly but in recent years has risen again. Between 1997 and 2007, the years before the financial crisis, the cause of wealth inequality was mostly due to the fact that the lower percentiles did not own any assets and most had negative net wealth. Following the financial crisis their net worth decreased significantly, with the bottom 10% reaching a negative net worth of more than nine million ISK in 2010. Since 2010 the lower percentiles have increased their net worth yearly although the bottom 10% have not yet reached a positive net worth in 2017. The difference between total assets of the lower percentiles, i.e. bottom 30% of the population, compared to the top 1% has decreased since 2010. Yet the difference between total assets of the middle percentiles compared to the top 1%, has gradually increased since 2010. The analysis in this thesis of the distribution of wealth in Iceland concludes that wealth inequality rose during the years prior to the financial crisis, reached its high point in 2010 and then decreased again. Yet what is also interesting from the analysis is that the structure of wealth inequality during the period has also changed. The main reason for wealth inequality in the twentieth century and the first decade of the 21st century was due to the fact that the lower percentile groups did not own any assets and had a net worth of zero or even negative. In the last few years these groups have all improved their net worth position, with only the bottom 10% still having a negative net 5 worth value in 2017. Even though net worth for all percentiles has improved, the top 1% has taken a significant lead compared to other percentiles. The difference between the net worth value of the top 1% compared to all other percentiles has increased in recent years. Therefore a main cause to economic inequality today is due to the fact macroeconomic conditions have given those individuals who sit on top of the wealth ladder the opportunity to increase their wealth proportionally more compared to other wealth groups which drives up economic inequality. 6 Contents Preface ...................................................................................................................... 4 Abstract ..................................................................................................................... 5 Contents .................................................................................................................... 7 Table of Figures ......................................................................................................... 9 Table of Tables ........................................................................................................ 10 1 Introduction ...................................................................................................... 11 2 Theoretical approach ........................................................................................ 13 2.1 What is wealth ........................................................................................... 13 2.2 Negative wealth ........................................................................................ 13 2.3 Thomas Piketty on wealth inequality ........................................................ 14 3 Development of wealth distribution ................................................................ 16 3.1 Global development in the postwar era .................................................... 16 3.2 Bubble economy starts emerging .............................................................. 17 3.3 Financial crisis 2008 ................................................................................... 17 3.4 Debt relief .................................................................................................. 18 3.5 Recent years .............................................................................................. 19 4 Data .................................................................................................................. 21 4.1 Principal Component Analysis ................................................................... 21 4.2 Total asset distribution .............................................................................. 22 4.3 Liabilities distribution ................................................................................ 25 4.4 Total net worth distribution ...................................................................... 28 4.5 Total annual income distribution .............................................................. 30 4.6 Total disposable income distribution ........................................................ 32 7 4.7 The income life cycle: ................................................................................ 34 5 Influential drivers of wealth distribution .......................................................... 37 5.1 Fiscal policy ................................................................................................ 37 5.2 Rate of return on capital vs. economic growth ......................................... 38 5.3 The housing market ................................................................................... 39 6 Conclusion ........................................................................................................ 41 7 Bibliography ...................................................................................................... 43 A The Kuznet ratio and the kuznet curve ............................................................. 47 B Karl Heinrich Marx ............................................................................................ 49 C Thomas Malthus ............................................................................................... 50 D Data .................................................................................................................. 51 E Measuring wealth distribution ......................................................................... 57 E.1 The wealth over people curve ................................................................... 57 E.2 The Lorenz Curve ....................................................................................... 58 E.3 Gini Coefficient .......................................................................................... 58 F Principal component analysis ........................................................................... 59 8 Table of Figures Figure 1.

Adaptive community-driven resource management is vital to build resilience. Only communities committed to ongoing learning can adapt to a continuously changing environment. This is why environmental education (EE) should be community-focussed and part of coastal and marine management. Key informants were interviewed in Ísafjörður in the Westfjords of Iceland to gather perceptions about local coastal and marine environmental issues and EE.

  • Ten Years After: Iceland's Unfinished Business
    18 October 2018 Ten Years After: Iceland´s Unfinished Business Thorvaldur Gylfason* 1. Introduction This study discusses the economic, political, and judicial aftermath of Iceland´s financial collapse in 2008. It considers lessons learned, or not learned, with emphasis on unsettled issues concerning the distribution of incomes and wealth, banking, and politics. The study makes three main points. First, the measurement of income flows and living standards needs to be adjusted in two respects. Just as assets must be assessed in two dimensions, in terms of their returns and risk, national incomes and wealth need to be gauged in terms of their level as well as their dispersion across the population. This is hard to do. Commonly used measures of the distribution of incomes and wealth are incomplete for two reasons. They customarily include only income from labor but not from capital and private wealth in tax havens and such is significantly underreported. Zucman (2013) reported that nearly $6 trillion of global household financial wealth goes unreported, at the time equivalent roughly to ten percent of world GDP (see also Zucman 2015). Further, macroeconomic flows and stocks, incomes and wealth, need to be assessed side by side because high incomes can be misleading if they are sustained by the depletion of stocks (natural resources, net foreign assets, social capital, etc.). This means that observers need beware of extolling the beauty of volcanoes that are about to erupt – as the IMF learned the hard way when its staff wrote as follows in 2007 (Wagner 2010, 11): Iceland’s medium-term prospects remain enviable.

Research on mental well-being can be divided in two categories, the hedonic aspect of well-being and the eudaimonic aspect of well-being. The focus of the concept of flourishing includes feelings (hedonic) and function (eudaimonic) in the measurement of mental well- being, combining positive feelings, social functioning, and psychological resources. In a previous study on flourishing in Europe, the highest prevalence was found in Denmark, and the other Nordic countries also scored among the highest. Iceland was not a participant country in the this study. The overall aim of the current study is to examine flourishing in Iceland and its prevalence and predictors.
