Wanderten in den vergangenen 25 Jahren zahlreiche Menschen aus Ostdeutschland ab, so ist dieser Trend per saldo jüngst zum Erliegen gekommen. Dies hat auch damit zu tun, dass sich die Arbeitsmarktperspektiven verbessert haben. Die durchschnittlichen Bruttomonatsverdienste der Vollzeitbeschäftigten liegen in Ostdeutschland jedoch erst bei etwa 70 Prozent der Verdienste im Westen. Die wirtschaftlichen Möglichkeiten der Menschen in Ostdeutschland liegen aber viel näher am westdeutschen Niveau. So betragen die verfügbaren Einkommen im Osten immerhin 84 Prozent in Relation zum Westen. Berücksichtigt man noch Unterschiede der Preisniveaus, so kommt man auf ein reales Konsumniveau im Osten, das bei etwa 90 Prozent des Westniveaus liegt. Nach dem amerikanischen Bürgerkrieg war die Lücke zwischen der Produktion je Einwohner in den Nord- und den Südstaaten etwa so groß wie vor 25 Jahren zwischen Ost- und Westdeutschland; in den USA hat es aber 100 Jahre gedauert, bis sich die Lücke bis auf 10 Prozent geschlossen hatte. Auch verglichen mit anderen Transformationsländern wie beispielsweise Tschechien oder Polen ist der Aufholprozess Ostdeutschland deutlich weiter.

Citizens of the German Democratic Republic (GDR) regained their civil liberties when the Berlin Wall fell 25 years ago. Since then, they have been able to travel freely and have been free to choose where to live and work. The fall of the Berlin Wall was quickly followed by preparations for German Unification at a speed unparalleled in history: the first free Volkskammer elections on 18 March 1990, the economic, monetary and social union on 1 July 1990, and finally, the unification of Germany when the GDR was included in the jurisdiction of the Basic Law of the Federal Republic of Germany. The integration of the economies of East and West Germany, however, has proven to be a drawn-out process.

Die Befunde zum Bruttoinlandsprodukt (BIP) je Einwohner und zur Produktivität Ostdeutschlands sind fast ein Vierteljahrhundert nach dem Fall der Berliner Mauer ambivalent: Verglichen mit der Ausgangssituation konnte die Ost-West-Lücke deutlich verringert werden. Lag das BIP je Einwohner 1991 in Ostdeutschland (ohne Berlin) erst bei einem Drittel des westdeutschen Niveaus, sind im Jahr 2013 zwei Drittel erreicht. Bei der Produktivität startete Ostdeutschland (ohne Berlin) mit 35% und weist im Jahr 2013 immerhin 76% des westdeutschen Niveaus auf.

In DSGE models, fiscal policy is typically described by simple rules in which tax rates respond to the level of output. We show that there is only weak empirical evidence in favor of such specifications in US data. Instead, the cyclical movements of labor and capital income tax rates are better described by a contemporaneous response to hours worked and investment, respectively. We show that conditioning on these variables is also desirable from a normative perspective as it significantly improves welfare relative to output-based rules.

This study on healthy young male students aimed to enlighten the associations between an individual’s financial decision making and surrogate makers for environmental factors covering long-term financial socialization, the current financial security/responsibility, and the personal affinity to financial affairs as represented by parental income, funding situation, and field of study. A group of 150 male young healthy students underwent two versions of the Holt and Laury (2002) lottery paradigm (matrix and random sequential version). Their financial decision was mainly driven by the factor “source of funding”: students with strict performance control (grants, scholarships) had much higher rates of relative risk aversion (RRA) than subjects with support from family (ΔRRA = 0.22; p = 0.018). Personality scores only modestly affected the outcome. In an ANOVA, however, also the intelligence quotient significantly and relevantly contributed to the explanation of variance; the effects of parental income and the personality factors “agreeableness” and “openness” showed moderate to modest – but significant – effects. These findings suggest that environmental factors more than personality factors affect risk aversion.

Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of financial system – a focus on its size, including both intermediation and other auxiliary “non-intermediation” activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980–2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries. As this is an initial exploration of the link between financial system indicators and growth and volatility, we focus on OLS regressions, leaving issues of endogeneity and omitted variable biases for future research.

Diverging European sovereign bond yields after 2008 are the most visible sign of the European debt crisis. This dissertation examines in a first step, to which extent the development of yields is driven by credit and liquidity risk, and how it is influenced by general uncertainty on financial markets. It can be shown that yields are driven to a significant degree by a flight towards bonds of high liquidity in times of high market uncertainty. In a second step, high yields are interpreted as a sign of an existing crisis in the respective country. Using the signals approach, the early-warning capabilities of four different proposals for the design of the scoreboard as part of the “Macroeconomic Imbalances Procedure” (introduced in December 2011 by the European Commission) are tested, advocating a scoreboard including a variety of many different indicators. In a third step, the methodology of the signals approach is extended to include also results on significance.

Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

Für die deutsche Wirtschaft stehen die Zeichen auf Erholung. Das reale Bruttoinlandsprodukt zog nach einem Rückgang im vergangenen Winterhalbjahr im Sommer 2013 wieder an. Das preisbereinigte Bruttoinlandsprodukt dürfte im Jahr 2013 um 0,6% und im Jahr 2014 um 2% zulegen. Während die Arbeitslosenquote im Jahr 2014 zurückgeht, wird sich die Verbraucherpreisinflation etwas beschleunigen.

In their innovative and frequently cited study on the impact watching television (TV) has on income aspirations and happiness, Luigino Bruni and Luca Stanca 2006, henceforth B&S) offer an alternative explanation of Easterlin's income-happiness paradox: “television viewing in contemporary society, by raising material aspirations, contributes to offset the effect of higher income on individual happiness” (B&S, p. 225). More generally, the paper contributes to the literature of economic psychology, addressing the determinants and formation of preferences. While the theoretical analysis of B&S and the hypothesis on the effect of TV on material aspirations are well-grounded, the empirical evidence they present to corroborate the TV hypothesis is rather weak. After correcting a technical inaccuracy of B&S' empirical analysis one obtains results which no longer confirm a significant, positive and robust impact of TV consumption on material aspirations. As discussed in the third section, the revised empirical result does not disprove B&S' main hypothesis on the role of TV in shaping individual preferences. However, it suggests applying a more direct approach of measuring the effect of TV on aspiration than that performed in B&S's empirical analysis.
