Abstract
This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk effects on other financial institutions; the commodity price bubble, and the ultimate demise of investment banking in the U.S. The study argues that the severity of the crisis is influenced strongly by changeable allocations of global savings coupled with excessive credit creation, which lead to over-pricing of varied types of assets. The study calls such process a “wandering asset-price bubble“. Unstable allocations elevate market, credit, and liquidity risks. Monetary policy responses aimed at stabilizing financial markets are proposed.

The Euro and the Competitiveness of European Firms

Economic Policy,
No. 57,
2009
Abstract
Much attention has been paid to the impact of a single currency on actual trade volumes. Lower trade costs, however, matter over and beyond their effects on trade flows: as less productive firms are forced out of business by the tougher competitive conditions of international markets, economic integration fosters lower prices and higher average productivity. We assess the quantitative relevance of these effects calibrating a general equilibrium model using country, sector and firm-level empirical observations. The euro turns out to have increased the overall competitiveness of Eurozone firms, and the effects differ along interesting dimensions: they tend to be stronger for countries which are smaller or with better access to foreign markets, and for firms which specialize in sectors where international competition is fiercer and barriers to entry lower.— Gianmarco I.P.

Obama und die Wende der US-Klimapolitik – ein Kommentar
Wilfried Ehrenfeld
Wirtschaft im Wandel,
No. 12,
2008
Abstract
Die Vereinigten Staaten von Amerika sind mit einem Anteil von rund 21% neben China (ebenfalls rund 21%) und der EU (ca. 16%) der größte CO2-Emittent der Erde. Anfang November haben die USA einen neuen Präsidenten gewählt: Barack Obama. Während des Wahlkampfs wurden zeitweilig Spekulationen laut, dass Arnold Schwarzenegger Umwelt- bzw. Energieminister werden soll, wenn Obama Präsident wird. Der Gouverneur von Kalifornien gilt als Vorreiter in Sachen Klimaschutz und nachhaltige Energiepolitik in den USA. Seine Position führte in der Vergangenheit wiederholt zu Spannungen zwischen ihm und Präsident George W. Bush. Schwarzenegger hatte mit dem ‚California Global Warming Solutions Act of 2006‘ ein Gesetz unterzeichnet, mit Hilfe dessen der Ausstoß von Treibhausgasen bis 2020 auf das Niveau von 1990 sinken soll. Im November 2008 unterzeichnete der Gouverneur eine Verordnung, die besagt, dass bis 2020 ein Drittel des Energieverbrauchs Kaliforniens aus erneuerbaren Quellen gewonnen werden soll. Zusammen mit sechs weiteren US-Staaten und vier kanadischen Provinzen will Kalifornien ab 2012 ein CO2-Emissionshandelssystem einführen.

Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Marian Berneburg
Schriften des IWH,
No. 28,
2008
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.

Evidence on the effects of inflation on price dispersion under indexation
Juliane Scharff, S. Schreiber
IMK Working Paper, No. 12/2008,
2008
Abstract
Die verzerrenden Auswirkungen von Inflation auf relative Preise sind das Hauptargument für Inflationsstabilisierung in Makromodellen mit Preisrigiditäten. Bei Indexierung von nicht optimierten Preisen implizieren diese Modelle einen nichtlinearen und dynamischen Einfluss von Inflation auf die Preis-Streuung im Querschnitt (relative Preisvariabilität, RPV). Wir schätzen eine verallgemeinerte Form dieser theoretischen Beziehung zwischen Inflation und RPV mit US-Daten. Wir bestätigen den Einfluss von Inflationsschwankungen, jedoch finden wir bisher vernachlässigte Endogenitätsverzerrungen, und unsere IV- und GMM-Schätzungen zeigen, dass die durchschnittliche (“Trend-“) Inflation bei der Indexierung signifikant ist. Die verzögerte Inflationsrate ist weniger wichtig.

Globalisation and the Competitiveness of the Euro Area
Filippo di Mauro, Katrin Forster
ECB Occasional Paper Series,
No. 97,
2008
Abstract
Against the background of increasing competition and other significant structural changes implied by globalisation, maintaining and enhancing competitiveness has evolved into one of the prime concerns in most countries. Following up on previous work (see in particular ECB Occasional Papers No. 30 and No. 55), this Occasional Paper examines the latest developments and prospects for the competitiveness and trade performance of the euro area and the euro area countries. Starting from an analysis of most commonly used, traditional competitiveness indicators, the paper largely confirms the findings of previous studies that there have been substantial adjustments in euro area trade. Euro area firms have taken advantage of the new opportunities offered by globalisation, and have at the same time been increasingly challenged by emerging economies. This is primarily reflected in the loss of export market shares which have been recorded over the last decade. While these can partly be related to the losses in the euro area's price competitiveness, further adjustment also seems warranted with regard to the export specialisation. Compared with other advanced competitors, the euro area remains relatively more specialised in labour intensive categories of goods and has shown only a few signs of a stronger specialisation in research-intensive goods. Nevertheless, the paper generally calls for a more cautious approach when assessing the prospects for euro area competitiveness, as globalisation has made it increasingly difficult to define and measure competitiveness. Stressing the need to take a broader view on competitiveness, specifically with a stronger emphasis on productivity performance, the paper also introduces a more elaborate framework that takes into account the interactions between country-specific factors and firm-level productivity. It thus makes it possible to construct more broadly defined competitiveness measures. Pointing to four key factors determining the global competitiveness of euro area countries - market accessibility, market size, technological leadership of firms and institutional set-up - the analysis provides further arguments for continuing efforts to increase market integration and strengthen the competitive environment within Europe as a mean of enhancing resource allocation and coping with the challenges globalisation creates.

Will Oil Prices Decline Over the Long Run?
Filippo di Mauro, Robert K. Kaufmann, Pavlos Karadeloglou
ECB Occasional Paper Series,
No. 98,
2008
Abstract
At present, oil markets appear to be behaving in a fashion similar to that in the late 1970s and early 1980s when oil prices rose sharply over an extended period. Furthermore, like at that time, analysts are split on whether such increases will persist or reverse, and if so by how much. The present paper argues that the similarities between the two episodes are not as strong as they might appear at first sight, and that the likelihood of sharp reversals in prices is not particularly great. There are a number of reasons in support of the view that it is unlikely that the first two decades of this century will mimic the last two decades of the previous century. First, oil demand is likely to grow significantly in line with strong economic growth in non-OECD countries. Second, on the supply side, OPEC is likely to enhance its control over markets over the next two decades, as supply increases in newly opened areas will only partially offset declining rates of production in other geologically mature non-OPEC oil regions. Moreover, while concerns about climate change will spur global efforts to reduce carbon emissions, these efforts are not expected to reduce oil demand. Finally, although there is much talk about alternative fuels, few of these are economically viable at the prices currently envisioned, and given the structural impediments, there is a reduced likelihood that the market will be able to generate sufficient quantities of these alternative fuels over the forecast horizon. The above factors imply that oil prices are likely to continue to exceed the USD 70 to USD 90 range over the long term.

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.

The Changing Role of the Exchange Rate in a Globalised Economy
Irina Bunda, Filippo di Mauro, Rasmus Rüffer
ECB Occasional Paper Series,
No. 94,
2008
Abstract
In addition to its direct effects on the global trading and production structure, the ongoing process of globalisation may have important implications for the interaction of exchange rates and the overall economy. This paper presents evidence regarding possible changes in the role of exchange rates in a more globalised economy. First, it analyses the link between exchange rates and prices, showing that there is at most a moderate decline in exchange rate pass-through for the euro area. Next, it turns to the effect of exchange rate changes on trade flows. The findings indicate that the responsiveness of euro area exports to exchange rate changes may have declined somewhat as a result of globalisation, reflecting mainly shifts in the geographical and sectoral composition of trade flows. The paper also provides a firm-level analysis of the impact of exchange rate changes on corporate profits, which suggests that overall this relationship appears to be relatively stable over time, although there are important cross-country differences. In addition, it studies the overall impact of exchange rates on GDP and the potential role of valuation effects as a transmission channel in the case of the euro area.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.
