The failure of exceptional monetary measures pursued in response to the financial crisis in advanced economies to achieve a strong recovery has created a widespread concern that these economies suffer from a chronic demand gap and face the prospect of stagnation. This article reviews and discusses the alternative views on the causes of the slowdown in accumulation and growth and the policies implemented and proposed to deal with it. It is argued that growing inequality, notably the secular decline in the share of wages, and financialisation are the main factors. Neither spending booms driven by financial bubbles, nor exporting unemployment through trade provides sustainable solutions. It is necessary to rebalance capital and labour, restrain finance and assign a greater role to the public sector in aggregate demand management and income and wealth distribution. However, the dominant neoliberal ideology rules out such socially progressive and economically effective solutions. Consequently, stagnation is likely to remain the new normal in the years to come with governments attempting to reignite growth by creating credit and asset bubbles and/or trying to export unemployment through beggar-thy-neighbour macroeconomic, labour market, trade and exchange rate policies, thereby generating financial and economic instability and tensions in international economic relations with significant repercussions for emerging and developing economies.

In the coming decades, the countries of the South will be facing the aging of the population faster than the countries of the North. This will have long-term economic consequences for the South but also for the North through the changing of international capital flows. To study the latter, we build a simple two-region two-period overlapping generations (OLG) model, assuming fully integrated financial markets. This allows us to determine the analytical expression of the world interest rate dynamics at general equilibrium and the resulting capital flows accruing to each of the two regions (the North and the South). From there, we analyze how a reduction in either fertility or mortality alters the magnitude of the international capital flows. Contradictory effects are evidenced. To clear-up any ambiguity and to study the South's demographic transition, which involves a succession of shocks, we propose numerical simulations. Even if the results stress that the institutional context and technological catching-up may matter, they suggest in a rather general way that the declines in both fertility and mortality tend to reduce the relative capital needs of the Southern economies and consequently their capital inflows. This, in turn, would be beneficial to the North's productive capacity, which should then hold more capital.

This article explains the problem of adjustment to the challenges of globalization in terms of the logic underpinning four distinct policy constraints, or trilemmas, and their interrelationship, and in particular the disturbances that arise from capital flows. The analysis of a policy trilemma was developed first as a diagnosis of exchange rate problems (the incompatibility of free capital flows with monetary policy autonomy and a fixed exchange rate regime); but the approach can be extended. The second trilemma we describe is the incompatibility between financial stability, capital mobility and national policy choice over exchange rates. The third example extends the analysis to politics, and looks at the strains in reconciling democratic politics with monetary autonomy and capital movements. Finally, we examine the security aspect and look at the interactions of democracy with capital flows and international order. The trilemmas, in short, depict the way that domestic monetary, financial, economic and political systems are interconnected with the international order, or the impossible policy choices at the heart of globalization. Frequently, the trilemmas conjure up countervailing anti-globalization tendencies and trends.

A drop in net FDI investment income has been the primary factor in the recent deterioration in the measured UK current account balance, with the trade balance relatively stable. We argue that financial engineering (with little net impact on the underlying international investment position for the UK) may have contributed to the decline in net FDI investment income, such that the headline current account balance cannot be interpreted as a sufficient indicator of the state of the UK's external position. A more granular analysis of cross-border financial linkages than is possible with currently-published data would be required in order to provide a comprehensive assessment of external sustainability.
