IWH-Chef: Sachsen-Anhalt ist nicht nur ChemieReint GroppDie Welt, 2. März 2026
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.
In the decade prior to the economic and financial crisis, Germany’s net exports increased in absolute terms as well as relative to the growing level of import intensity of domestically produced export goods and services. This article analyses the direct and indirect employment effects induced both by exports as well as by of the import intensity of the production process of export goods and services on the skills used. It shows that Germany’s export surpluses led to positive net employment effects. Although the volume of imports of intermediate goods increased and was augmented by the rise in exports, it could not undermine the overall positive employment effect.
This paper discusses a tax-transfer scheme that aims to address the under-provision problem associated with the private supply of international public goods and to bring about Pareto optimal allocations internationally. In particular, we consider the example of the global public good ‘climate stabilization’, both in an analytical and a numerical simulation model. The proposed scheme levies Pigouvian taxes globally, while international side-payments are employed in order to provide incentives to individual countries for not taking a free-ride from the international Pigouvian tax scheme. The side-payments, in turn, are financed via environmental taxes. As a distinctive feature, we take into account ancillary benefits that may be associated with local public characteristics of climate policy. We determine the positive impact that ancillary effects may exert on the scope for financing side-payments via environmental taxation. A particular attractive feature of ancillary benefits is that they arise shortly after the implementation of climate policies and therefore yield an almost immediate payback of investments in abatement efforts. Especially in times of high public debt levels, long periods of amortization would tend to reduce political support for investments in climate policy.
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.
While there has been much discussion of the role of liquidity in the recent financial crises, there has been little discussion of the use of macroeconomic aggregation techniques to measure total liquidity available to the market. In this paper, we provide an approximation of the liquidity development in six Euro area countries from 2003 to 2013. We show that properly measured monetary aggregates contain significant information about liquidity risk.
The continued expansionary policy of the Federal Reserve gives rise to speculation whether the Fed will be able to maintain price stability in the coming decades. Most of the scientific work relating money to prices relies on broad monetary aggregates (i.e. M2 for the United States). In our paper, we argue that this view falls short. The historically unique monetary expansion has not yet fully reached M2. Using a cointegration approach, we aim to show the hidden risks for the future development of M2 and correspondingly prices. In a simulation analysis we show that even if the multiplier remains substantially below its pre-crisis level, M2 will exceed its current growth path with a probability of 95%.
We examine the determinants of Japanese foreign direct investment (FDI) focusing on institutional and social factors. Using panel data on 59 countries from 1995 to 2008, we find that host countries with free and open markets and greater cultural distance from Japan attract Japanese FDI. Good institutions, such as a well-developed legal framework and an effective government, are important in promoting Japanese FDI to emerging economies, whereas fewer regulatory restrictions, lower tax burden, and more religious diversity attract Japanese FDI to developed countries. We find that corruption stimulates Japanese FDI to developed countries, which is contrary to most previous research.
Structural VAR studies disagree with narrative accounts about the history of monetary policy disturbances. We investigate whether employing the narrative monetary shocks as a proxy variable in a VAR model aligns both shock series. We find that it does not.
In dieser Studie wird untersucht, ob die Preisentwicklung auf Rohstoffmärkten statistische Anhaltspunkte für spekulative Preisblasen liefert. Diese Frage ist von zentraler Bedeutung in der wirtschaftspolitischen Debatte um die Regulierung des Handels von Rohstoffen. Es kann statistisch gezeigt werden, dass sich Rohstoffpreise gelegentlich explosiv verhalten. Die stärkste Evidenz für explosives Verhalten gibt es bei den Industrierohstoffen. Auch bei Nahrungsmittelpreisen können Phasen explosiven Verhaltens statistisch nachgewiesen werden. Eine wichtige Schlussfolgerung ist, dass die Ursachen explosiven Verhaltens auf Rohstoffmärkten und die Effekte von Preisblasen auf die Entscheidungen von Konsumenten und Investoren sowie Verteilungseffekte systematisch untersucht werden müssen.
Based on 69 sample countries, this paper examines the effect of macroeconomic fundamentals on real effective exchange rates (REER) in these sample countries. Using the misalignment of actual REER from its equilibrium level, we have estimated the factors explaining the extent of currency over- or under-valuation. Overall, we find that the higher the flexibility of the currency regime, the lower is the misalignment. The estimates are robust to different sub-samples of countries. We then explore the impact of such misalignment on the probability of a currency crisis in the next period, indicating the extent to which misalignment could be used as a leading indicator of a potential crisis. This paper thus makes a new contribution to the debate on the choice of exchange rate regime by bringing together real exchange rate misalignment and currency crisis literature.
