Most mainstream neoclassical economists completely failed to anticipate the crisis which broke in 2007 and 2008. There is however a long tradition of economic analysis which emphasises how growth in a capitalist economy leads to an accumulation of tensions and results in periodic crises. This paper first reviews the work of Karl Marx who was one of the first writers to incorporate an analysis of periodic crisis in his analysis of capitalist accumulation. The paper then considers the approach of various subsequent Marxian writers, most of whom locate periodic cyclical crises within the framework of longer-term phases of capitalist development, the most recent of which is generally seen as having begun in the 1980s. The paper also looks at the analyses of Thorstein Veblen and Wesley Claire Mitchell, two US institutionalist economists who stressed the role of finance and its contribution to generating periodic crises, and the Italian Circuitist writers who stress the problematic challenge of ensuring that bank advances to productive enterprises can successfully be repaid.

This paper presents an overview of different models which explain financial crises, with the aim of understanding economic developments during and possibly after the Great Recession. In the first part approaches based on efficient markets and rational expectations hypotheses are analyzed, which however do not give any explanation for the occurrence of financial crises and thus cannot suggest any remedies for the present situation. A broad range of theoretical approaches analyzing financial crises from a medium term perspective is then discussed. Within this group we focused on the insights of Marx, Schumpeter, Wicksell, Hayek, Fisher, Keynes, Minsky, and Kindleberger. Subsequently the contributions of the Regulation School, the approach of Social Structures of Accumulation and Post-Keynesian approach, which focus on long-term developments and regime shifts in capitalist development, are presented. International approaches to finance and financial crises are integrated into the analyses. We address the issue of relevance of all these theories for the present crisis and draw some policy implications. The paper has the aim to find out to which extent the different approaches are able to explain the Great Recession, what visions they develop about future development of capitalism and to which extent these different approaches can be synthesized.

The dossier first discusses the impact of colonialism on introducing foreign plants and thus disrupting ecosystems. Subsequently the case of the knotweed, a plant introduced from Japan to the UK and now considered a threat to biodiversity is explored. The complex economy built around the plant consisting of regulations, pesticides, experts, and landowners is then explored.

As seen with the United Nations significant promotion of the Sustainable Development Goals (SDGs) in the past few years, the issue of global development is of growing concern to many international organizations. As humanity continues to become more interconnected through globalization, the inequalities and injustices experienced by inhabitants of impacted countries becomes increasingly clear. While this issue can be observed in the papers of different types (e.g., different schools of thought) of economists throughout the world, the work of behavioral and complexity economists offer a unique, collaborative perspective on how to frame decisions for individuals in a way that can positively reverberate throughout society and throughout time.
