In this blog article, Dirk Brockmann illustrates how strong heterogeneities, cluster-like structures and high variability in node connectivities can naturally emerge in growing networks.

MERCOSUR (Mercado Común del Sur or Common Southern Market) was the first formalized attempt to integrate South American countries economically and politically.

Markets are the focus in modern economics: when they work, when they don’t and what we can or can’t do about it. There are many ways to study markets and how we do so will inevitably affect our conclusions about them, including policy recommendations which can influence governments and other major organisations. Pluralism can be a vital corrective to enacting real policies based on only one perspective and a plethora of approaches provide alternatives to the canonical view. Although they have differing implications, these approaches share the idea that we should take a historical approach, analysing markets on a case-by-case basis; and they share a faith in the power of both individuals and collectives to overcome the problems encountered when organising economic activity.

Firms are the primary places where economic activity takes place in modern capitalist economies: they are where most stuff is produced; where many of us spend 40 hours a week; and where big decisions are made about how to allocate resources. Establishing how they work is hugely important because it helps us to understand patterns of production and consumption, including how firms will react to changes in economic conditions and policy. And a well-established literature – led by post-Keynesians and institutionalists – holds that the best way to determine how firms work is to…wait for it...ask firms how they work. This a clearly sensible proposition that is contested in economics for some reason, but we’ll ignore the controversy here and just explore the theory that springs from this approach.

One method of economic modelling that has become increasingly popular in academia, government and the private sector is Agent Based Models, or ABM. These simulate the actions and interactions of thousands or even millions of people to try to understand the economy – for this reason ABM was once described to me as being “like Sim City without the graphics”. One advantage of ABM is that it is flexible, since you can choose how many agents there are (an agent just means some kind of 'economic decision maker' like a firm, consumer, worker or government); how they behave (do they use complicated or simple rules to make decisions?); as well as the environment they act in, then just run the simulation and see what happens as they interact over time.

hether it's working for free in exchange for 'experience', enduring poor treatment in the name of being 'part of the family', or clocking serious overtime for a good cause, more and more of us are pushed to make sacrifices for the privilege of being able to do work we enjoy. Work Won't Love You Back examines how we all bought into this 'labour of love' myth: the idea that certain work is not really work, and should be done for the sake of passion rather than pay.

The productive work of widely distributed academic research has contributed substantially, over the postwar period, to important advances in our understanding. It has also offered a clearer recognition of many unresolved problems. Never theless, the progress achieved over the last decades, ex hibited by the systematic application of "theory" to actual issues and observable problems, could not overcome a per vasive sense of dissatisfaction.
