Financial stress and economic activity in Germany

The financial crisis and the European sovereign debt crisis have shown that financial stress may be an important driver for economic activity. In this paper, I derive a financial stress index for Germany, using a dynamic approximate factor model that summarizes a stress component of various financial variables. Subsequently, I analyze the effects of financial stress on economic activity in a threshold vector autoregressive model. I find that if the index exceeds a certain threshold, an increase in financial stress causes economic activity to decelerate significantly, whereas if it is below this threshold, economic activity remains nearly unaffected.     

Nationale Geldsch?pfung zersetzt den Euroraum

The Eurosystem has been operating in crisis mode for more than four years now. Massive quantitative and qualitative easing in its monetary policy stance are the visible marks of its response to the turbulence in the financial sector. This policy aims primarily at maintaining financial stability in the euro area by providing vast liquidity support to commercial banks that are operating in nationally segmented banking systems. The sovereign debt crises in some member countries further exacerbate the segmentation problem along country borders. As a side effect, cross-border capital flows are substituted by money market operations by the national central banks. The latter are engaging more and more often in substantial balance-of-payments financing, and financial risks are shifted from investors to European taxpayers via the Eurosystem. Symptomatically, this shows up in exploding TARGET2 positions in the national central banks’ balance sheets. The longer this process continues, the stronger the centrifugal forces become that ultimately might burst the single currency. A solution requires a euro area-wide regulatory approach for the financial sector. Next to a uniform scheme for banking regulation, supervision and resolution, we recommend the comprehensive introduction of contingent convertible bonds (CoCos) as a major refinancing source for the banking industry. As this proposal cannot be introduced overnight, national and European banking resolution funds are necessary in the short run. The latter do not rescue banks, but they kick in as soon as a bank’s equity is depleted in order to wind down failing banks in a systemically prudent way.     

Real Options: Experimental Evidence

Empirical testing of the real options theory has been very limited. This is primarily due to various inherent problems with obtaining field data for many components of real options theory. This paper utilizes experimental methodology to generate the data. The advantage of the experimental approach is that it enables the investigator to generate reliable and replicable data in a controlled environment. The results of the experiment indicate that fundamental insights of real options theory are not evident to individual investors. The majority invested too early and thus failed to recognize the benefit of the option to wait. However, when the investors had to compete with others for the right to invest, their bids generally reflected the value of the embedded option. Furthermore, as predicted by the theory, their bids increased with greater uncertainty about future cash flows from the investment.
