Unit root tests of the current account balance: implications for international capital mobility

The extent of international capital mobility is assessed in a time series context. The possibility that the current account balance of different 0ECD countries contains a unit root is explored. It is shown that if the ratio of the current account balance to GDP is found to be integrated of the order of one, the country is likely to be part of the world capital market. The results for the whole period 1950–1988 indicate that the current account balance of at least Germany, Japan and the United States contains a unit root. Considering the subperiods before and after 1972 it is shown that international capital mobility increased after the breakdown of the Bretton Woods System.     

Does Libertarian Paternalism Reconcile Merit Goods Theory with Mainstream Economics?

In the wake of Musgrave's move to question the absolute hegemony of individual preferences for normative economics in the 1950's by propounding the existence of merit goods, a recent book by Thaler and Sunstein is now making a similar claim under the label of ‘libertarian paternalism’. This paper tackles the question of why the framework of libertarian paternalism has received a so much more friendly reception among economists than the theory of merit goods. The main reason is a better foundation, not only for the conditions under which paternalism may be justified but also for the tools that should be applied, utilizing transaction cost theory.     

Corporate leverage and the collateral channel

We investigate whether and how corporate leverage depends on the structure of corporate assets. Based on a large panel dataset of US firms from 1990 to 2010, we show that property, plant and equipment are important drivers of the collateral channel, while inventories and receivables are less important. The collateral channel is more pronounced for firms that have to rely on banks and trade creditors to raise debt finance, but it has become weaker for these firms after the start of the financial crisis. Our study provides new evidence on the cross-sectional and time-varying importance of the collateral channel for corporate leverage.     

Finanzielle Repression — ein Instrument zur Bewältigung der Krisenfolgen?

Financial repression committed by central banks has been put forward as a means to secretly reduce the real burden of high public debts. Financial repression has allegedly played an important role in the impressive reduction of the US debt ratio after World War II. A mix of conventional budget consolidation and rapid growth was the main driver in this relative debt reduction with a minor role for financial repression. But does financial repression really exist? The authors express different opinions on evidence for this concept. Those authors who find that there are indicators of financial repression fear redistributive tendencies between debtors and creditors and high opportunity costs in the form of savings and investment distortions. Therefore, financial repression is not a “cure” for the high public debts amassed in the euro area during the recent sovereign debt and banking crisis. Furthermore, the high sovereign debts in the euro area may threaten economic development and impose high costs on society. Therefore, reducing these debts is politically highly relevant, and fiscal policy should be characterised by a modest reduction in government spending and/or tax increases, combined with a policy promoting economic growth. Macroprudential regulations should supplement this financial policy.
