Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays

No. 28,

Abstract
Many situations in the history of the stock markets indicate that assets are not always efficiently priced. But why does it matter whether the stock market is efficiently priced? Because “well-functioning financial markets are a key factor to high economic growth”. (Mishkin and Eakins, 2006, pp. 3-4) In three essays, it is the aim of the author to shed some more light on the topic of market efficiency, which is far from being resolved. Since European equity markets have increased in importance globally, the author, instead of focusing on US markets, looks at a unified European equity market. By testing for a random walk in equity prices, revisiting Shiller’s claim of excess volatility through the means of a vector error correction model, and modifying the Gordon-Growth-Model, the book concludes that a small degree of inefficiency cannot be ruled out. While usually European equity markets are pricing assets correctly, some periods (e.g. the late 1990s and early 2000s) show clear signs of mispricing; the hypothesis of a world with two states (regime one, a normal efficient state, and regime two, a state in which markets are more momentum driven) presents a possible explanation.

German Economy on the Brink of Recession
Wirtschaft im Wandel,
2. Sonderausgabe
2008
Abstract
In autumn 2008, the word economy is in a downswing, caused by the commodity and energy price hike of the first half of the year, housing crises in the US and some other important countries, and in particular by the financial crisis that has recently intensified. The downswing will continue this year and for some time during 2009, and will only come to an end later next year if governments and central banks succeed in stabilizing financial markets in the coming months. In this case, lower prices of commodities and still high growth dynamics in important emerging markets countries will lead to a tentative revival of the world economy.
The German economy is on the brink of a recession. It is particularly vulnerable to a global downswing because exports of investment goods are of upmost importance for the overall economy. Because the uncertainty about the worldwide effects of the financial crisis is very high, the forecast is split. A more probable scenario is based on the assumption of a stabilizing world economy. In this scenario, the growth rate of the German economy in 2009 is 0.2%. The second scenario is based on the assumption of a worldwide recession next year and forecasts that German GDP will shrink by 0.8% in 2009.
Concerning policy, the institutes recommend a strengthening of the capital base of banks via injection of government money. This should be done in a way that gives incentives to banks for attracting additional capital from private sources.
A special chapter of the report analyzes the nature and causes of the price hikes of energy and commodities in the first half of 2008.

Stages of the Ongoing Global Financial Crisis: Is There a Wandering Asset Bubble?
Lucjan T. Orlowski
IWH Discussion Papers,
No. 11,
2008
Abstract
This study argues that the severity of the current global financial crisis is strongly influenced by changeable allocations of the global savings. This process is named a “wandering asset bubble”. Since its original outbreak induced by the demise of the subprime mortgage market and the mortgage-backed securities in the U.S., this crisis has reverberated across other credit areas, structured financial products and global financial institutions. Four distinctive stages of the crisis are identified: the meltdown of the subprime mortgage market, spillovers into broader credit market, the liquidity crisis epitomized by the fallout of Bear Sterns with some contagion effects on other financial institutions, and the commodity price bubble. Monetary policy responses aimed at stabilizing financial markets are proposed.

Abstract
This study argues that the severity of the current global financial crisis is strongly influenced by changeable allocations of the global excess liquidity. This process is named a “wandering asset bubble”. Since its original outbreak induced by the demise of the subprime mortgage market and the mortgage-backed securities in the U.S., this crisis has reverberated across other credit areas, structured financial products and global financial institutions. Four distinctive stages of the crisis are distinguished: the meltdown of the subprime mortgage market, spillovers into broader credit market, the fallout of Bear Sterns with some contagion effects on other financial institutions, and the commodity price bubble. Monetary policy responses aimed at stabilizing financial markets are proposed.

Business Cycle Forecast: On the Edge?
Wirtschaft im Wandel,
No. 9,
2008
Abstract
During the summer of 2008, the world economy was further slowing. The financial crisis affects the real economy by tightened credit standards in the US and in the European Union, and housing markets are now in a severe crisis not only in the US, but also in some countries in Western Europe. Finally, consumption of households is affected by stagnating real disposable incomes due to the energy price hike. The slowing world economy, however, has caused the oil price to fall since July, and most emerging markets economies are, up to now, quite resilient.
In Germany, sentiment has deteriorated significantly. Production appears to be about stagnating in the summer. During winter, the devaluation of the euro and a beginning pick up of demand since July will help producers of tradable goods in Germany. Domestic demand will be supported by lower energy prices and healthily growing wage incomes. All in all, gross domestic product (gdp) (adjusted for the number of working days) will increase by 1,8% this year and by 0,8% in 2009.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

Parenting Benefit – A New Risk for Companies
Nicole Nulsch, Henry Dannenberg
Wirtschaft im Wandel,
No. 7,
2008
Abstract
One of the aims of the new parenting benefit – introduced by the German government in January 2007 – is to motivate fathers to take parental leave in order to take care of their young children. Until now, the effects of the parenting benefit have been discussed predominantly from the viewpoint of family policy. In contrast, this paper analyses how companies are affected by the new law. In 2007, the number of fathers who stayed at home to spend more time with their children increased significantly. More than half of the working applicants were already fathers. In the past, it was easy for companies to reduce their risk of losing an important employee due to the birth of a child as companies rather hired men than women. But this strategy will be less important in the future. It is expected that the risk-environment of companies will change because of a larger group of fathers taking parental leave. Such a changed risk-environment could increase the career opportunities of women and might reduce the gender wage gap. However, it is also expected that the overall risk of companies increases. Assumed that companies need equity to cover risks, an increase of the overall risk reduces investment opportunities if it is not possible to increase equity in the same way. This could influence the current economic development negatively.

Business Cycle Forecast, Summer 2008: Price Hikes and Financial Crisis Cloud Growth Prospects
Wirtschaft im Wandel,
No. 7,
2008
Abstract
In the summer of 2008 the turmoil on financial markets and that on the markets for energy dim the prospects for the world economy. The acceleration of the oil price hike during the first half of the year has led to an increase in expected inflation and to higher interest rates on capital markets, while stock prices are going down. At the same time, the financial crisis is far from over, and banks in the US and in Western Europe continue in their efforts to consolidate their balance sheets. Thus, the expansion of credit supply will be scarcer in the next quarters. All this means that demand will slow in the developed economies during the next quarters. However, the massive fiscal stimulus will help the US economy to stabilize, and the world economy still benefits from the high growth dynamics in the emerging markets economies. All in all, the developed economies will not reach their potential growth rate before the second half of 2009. In Germany, the upswing comes to a temporary halt during summer of this year. Slowing foreign demand and the oil price hike induce firms to postpone investments, and private consumption, the soft spot of the upswing in Germany, is still sluggish due to high inflation rates that impair purchasing power. For the end of 2008, chances are good that growth in Germany accelerates again, because German exporters are still penetrating emerging markets as competitiveness does not diminish. All in all, the German economy will grow by 2.3% in 2008 (mainly due to the very high dynamics at the beginning of the year) and by 1.3% in 2009. A main risk of this forecast is that monetary policy fails in easing the high inflationary pressures. As to fiscal policy, efforts to reach sustainable public finances should not weaken.

Eastern German Economy: No Catching-up in 2008 and 2009
Wirtschaft im Wandel,
No. 6,
2008
Abstract
In the New Lander, growth of production is characterized by two diverging developments. On the one hand, the manufacturing sector has expanded strongly while the public service sector as well as the retail sectors has considerably damped economic activity. On the other hand, those firms primarily bound to local markets have gained hardly any momentum, whereas others have been stimulated by external markets in Western Germany and abroad. These differences are mainly due to weak local demand in the wake of a low purchasing power and an ongoing reduction in the population. At the same time, export-oriented firms in the manufacturing sector have benefited from strong external demand, and they will further benefit from it, although somewhat less owing to the slowing world economy. However, as East German exporting firms are less exposed to those countries where the ongoing crisis in the real estate and the financial sector has unfolded its dampening effects the most, they are also less prone to it. Accordingly, gross domestic product will increase by 1,7% this year and 0,8% in 2009. This translates into further improvements on labor markets. Registered unemployment will fall below one million. In particular, manufacturing firms and the private business service sector will increase their demand for labor.

International Financial Integration and Stability: On the Causes of the International Banking Crisis 2007/08 and Some Preliminary Lessons.
Diemo Dietrich, Achim Hauck
Wirtschaft im Wandel,
No. 5,
2008
Abstract
Since its beginning, the recent financial market turmoil that has come to be known as the „subprime crisis“ has provoked considerable controversy among both, policymakers and scientists. The debate mainly focuses on two questions. The first is whether and how short-term measures should be taken to stabilize the global financial system. The second is which general lessons can be drawn from this crisis. Up to now, several potential causes of the crisis have been discussed in a more or less isolated manner. However, a predominant source of the crisis has not been identified yet. Accordingly, there is still a lack of knowledge regarding general consequences of the crisis for economic policy.
The purpose of this article is twofold. First, we show that to a large extent the crisis is due to the economic integration of formerly peripheral countries into the world economy that led to significant savings and investment imbalances. Thus, we argue that the crisis not only is a global phenomenon in its effects but also has global roots. Based on this argument, the second purpose of our paper is to derive implications for economic policy, where we also discuss the consequences for the future design of the global financial architecture.
