This paper analyzes the equilibrium pricing implications of contagion risk in a two-tree Lucas economy with CRRA preferences. The dividends of both trees are subject to downward jumps. Some of these jumps are contagious and increase the risk of subsequent jumps in both trees for some time interval. We show that contagion risk leads to large price-dividend ratios for small assets, a joint movement of prices in the case of a regime change from the calm to the contagion state, significantly positive correlations between assets, and large positive betas for small assets. Whereas disparities between the assets with respect to their propensity to trigger contagion barely matter for pricing, the prices of robust assets that are hardly affected by contagion and excitable assets that are severely hit by contagion differ significantly. Both in absolute terms and relatively to the market, the price of a small safe haven increases if the economy reaches the contagion state. On the contrary, the price of a small, contagion-sensitive asset exhibits a pronounced downward jump.
This article discusses the effects of the countercyclical premium discussed in insurance supervision in the context of Solvency II. While the basic principle of introducing countercyclical elements into Solvency II is endorsed, the authors argue for a system based on market scenarios which would enforce stricter capital requirements in boom times and less strict requirements in times of crisis.
The European Commission's Green Paper "The EU corporate governance framework" raises 25 questions in order to assess the effectiveness of the current corporate governance framework for European companies. The authors contribute to the EU's consultation, respond to the 25 questions and comment on the suggestions set out in the Green Paper.
Prodigal Italy Greece Spain?
(2011)
Contrary to widely held perceptions, workers in the southern European states that are most afflicted by the sovereign debt crisis work hard. However, labor productivity in these countries lags far behind the EU average. Structural reforms to boost productivity should be at the top of the reform agenda.
Reforms or bankruptcy?
(2011)
Almost 20 Greek academic economists from renowned universities in Europe and the US have prepared a one-page statement regarding the Greek crisis. In their statement the economic experts call upon the Greek public to accept the economic program of structural reforms, privatization, efficient tax collection, and shrinking of the public sector proposed and financed by the EU partners and the IMF. Among the signatories are this year's Nobel Prize winner Christopher Pissarides and Michalis Haliassos, Director of the Center for Financial Studies and Professor for Macroeconomics and Finance at the House of Finance.
The bail-in puzzle
(2011)
Under the current conditions of a global financial crisis, notably in Europe’s banking industry, the governance role of bond markets is defunct. In fact, investors have understood that bank debt will almost always be rescued with taxpayers’ money. The widespread practice of government-led bank bailouts has thus severely corrupted the bond market, leading to the underestimation of risk and, as a consequence, the destruction of market discipline. Any feasible solution to the bank-debt-is-too-cheap problem will have to re-install true default risk for bank bond holders.
