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.

The Transition to Post-industrial BMI Values Among US Children

NBER Working Paper No. 13898,
No. 13898,
2008
Abstract
In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some historical BMI values for comparison. The increase in BMIZ values during the period considered was on average 1.3σ (95% CI: 1.16σ; 1.44σ) among black girls, 0.8σ for black boys, 0.7σ for white boys, and 0.6σ for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black females, the rate of increase tended to accelerate among all four groups born in the mid-1950s to early-1960s with the contemporaneous spread of TV viewing. The rate of increase levelled off somewhat thereafter. There is some indication that among black boys and white girls born after c. 1990 adiposity has remained unchanged or perhaps even declined. The affects of the IT revolution of the last two decades of the century is less evident. Some regional evidence leads to the speculation that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We infer that the incremental weight increases are associated with the labor-saving technological developments of the 20th century which brought about many faceted cultural and nutritional revolutions.

Heterogeneity in Lending and Sectoral Growth: Evidence from German Bank-level Data

International Economics and Economic Policy,
2006
Abstract
This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

Business Cycles and FDI: Evidence from German Sectoral Data
Claudia M. Buch, A. Lipponer
Review of World Economics,
No. 4,
2005
Abstract
Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period 1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response to a real depreciation of the domestic currency.

The Olympic Games raise hopes for regional development policy: Economic effects of the infrastructure investments planned for the Olympic Games in 2012 in Leipzig
Peter Franz, Franz Kronthaler
Wirtschaft im Wandel,
No. 7,
2003
Abstract
Together with the cities of Chemnitz, Dresden, Halle and Riesa the East German city of Leipzig has applied as venue for the Olympic Games 2012. With its application Leipzig competed with four economically by far stronger West German cities (Stuttgart, Frankfurt, Düsseldorf, Hamburg). On April 12, 2003 the National Olympic Committee had to elect the national candidate for 2012 out of this bundle of five applying cities and nominated Leipzig. With the organization of this big event the city of Leipzig and its partner cities expect a strong impulse for regional development. This study tries to estimate the potential economic effects of the planned investment with regard to infrastructure. Important results: Regarding directly the job effects connected with the investment and development of the infrastructure about 3,500 additional jobs are to be expected for a period of ten years. The infrastructure investment planned so far for the Olympiad will contribute only partially to eliminate important infrastructural bottlenecks in the region. Nevertheless the planned infrastructure facilities would have the effect that the new ‘olympia region Leipzig’ would remain attractive also after 2012 as venue for large sport events.
