In 1803 Louis Poinsot, a French physicist, wrote a book of great success, Elements de Statique, which was destined to have practical and social influences unimaginable to the same author.

In the last few years the impact of income distribution on macroeconomic dynamics has received growing academic attention.

Long periods of unequal incomes spur borrowing from the rich, increasing the risk of major economic crises

Higher income inequality in developed countries is associated with higher domestic and foreign indebtedness

We analyze shareholders’ incentives to change the leverage of a firm that has already borrowed substantially. As a result of debt overhang, shareholders have incentives to resist reductions in leverage that make the remaining debt safer.

Budget cuts can be dangerous. Inspired by the wrenching experience in Greece, increasing attention is now being paid to the fact that austerity may fail to reduce the government deficit if the economy declines in response, as is likely in a liquidity trap (Delong and Summers 2012).

These are truly testing times. The world economic order – capitalism – is being called into question following the Lehman crisis. The world’s best form of societal organization – democracy – is being challenged by the economic success of autocratic countries such as China and Singapore.

In modern economies, individuals and companies engage in innovative activities, discovering new ways to use existing physical and human capital, and new technologies in which to invest.

The crisis has exposed the failure of economic models to deal sensibly with endogenously generated crises propagating from the financial sectors to the real economy, and back again.

In a classic book and subsequent articles, Obstfeld and Taylor (2004) have shown how the broad contours of international financial history over the past century and a half can be well understood by appealing to the famous economictrilemma which emerges from the standard Mundell-Fleming model many of us still teach our undergraduates.

The euro area’s sovereign debt crisis continues though significant steps have been taken to resolve it.

In preparing this paper I have decided not to embark upon the decades-old issue of optimal-currency areas and governance as such. I assume that one of my colleagues on the panel will do that. Instead I will present an historical case of over-indebtedness of parts of a common-currency area somewhat similar to the present challenge of Europe, or rather of the Euro area with its common currency.

Investment in productive capabilities provides the foundation for economic growth.
