Relative risk aversion, relative prudence and comparative statics under uncertainty: The case of (μ, σ)‐preferences

From the expected‐utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We characterize the magnitudes of relative risk aversion and relative prudence in terms of the two‐parameter, mean‐standard deviation approach. We demonstrate that this characterization is instrumental in obtaining comparative static results in the two‐parameter setting. We further relate our findings to the results in the expected‐utility framework.     

Factor Taxation, Income Distribution and Capital Market Integration

This paper addresses the optimal mix of capital and wage taxation when policymakers maximize the political support of workers and capitalists, subject to a fixed revenue requirement. Capital market integration increases the efficiency costs of a tax on capital but simultaneously changes the political equilibrium through its effect on the distribution of factor incomes. These distributional effects are directly opposed in the capital importing and the capital exporting region. While the capital tax rate will always be lowered in the capital importing region, the tax rate in the exporting country will rise when political resistance to market-induced changes in the distribution of income is sufficiently high.     

Macroeconomic Fluctuations and Bank Lending: Evidence for Germany and the Euro Area

Abstract. This paper analyzes the dynamic response of loans to the private sector and of economic activity to aggregate supply, demand and monetary policy shocks in Germany and the euro area based on a standard macroeconomic VAR using sign restrictions to identify the structural shocks. The main results of this analysis are that (i) with the exception of the response to the supply shock in Germany, the response of loans to the three macroeconomic shocks is rather weak and in most cases insignificant; (ii) the 2000–05 credit slowdown and weak economic performance in Germany were primarily driven by adverse supply shocks; and (iii) the marked slowdown in credit creation in Germany over this period actually represents a realignment of the outstanding stock of loans with its deterministic level. In order to assess the role of bank lending in the transmission of macroeconomic shocks, we further perform counterfactual simulations and analyze the dynamic responses of German loan subaggregates in order to test the distributional implications of potential credit market frictions. These exercises do not indicate that credit market frictions play an amplifying role in the transmission of macroeconomic fluctuations.     

Dynamic hedging of paper with T bill futures

Despite the growing importance of the commercial paper market there is no empirical work investigating the hedging performance of dynamic hedging strategies versus traditional static hedging strategies. This article proposes a dynamic hedging model for commercial paper that takes advantage of time dependencies present in the joint density of commercial paper and T-bill futures. The hedging effectiveness of the dynamic model is compared to that of the static regression model. There is clear evidence that dynamic hedging is superior to static hedging in terms of both total variance reduction and expected utility maximization. These results hold even when transactions costs are explicitly taken into account. © 1998 John Wiley & Sons, Inc. Jrl Fut Mark 18:925–938, 1998     

Zero‐interest Rate Policy and Unintended Consequences in Emerging Markets

Since 2009, central banks in the major advanced economies have held interest rates at very low levels to stabilise financial markets and support the recovery of their economies. This paper outlines the unintended consequences of the prolonged period of very low world funding interest rates in emerging markets. The paper is informed by a Mises–Hayek‐BIS view on credit booms and Mises' law of unintended consequences. Consistent with the presented credit boom view, I provide evidence that the very low world funding interest rates are associated with a rise in volatile capital flows and asset market bubbles in fast‐growing emerging markets. In line with Mises' law, I further show that these unintended consequences give rise to a new wave of interventionism as policymakers in emerging markets increasingly reintroduce financially repressive measures to isolate the economies from foreign capital inflows.     

Budgetdefizit und Leistungsbilanzsaldo: Ein weiterer Kommentar

Summary In this comment we point out that a consistent policy cannot rely solely on the instrument of demand management to attain internal and external stability simultaneously.     

Internationalization of Blue-Chip versus Mid-Cap Stock Indices: an Empirical Analysis for France,Germany, and the UK

The paper analyzes the question whether blue-chip stock indices provide a larger degree of internationalization than mid-cap stock indices. Specific focus lies on internationalization of indices in France, Germany, and the UK. Additionally, we analyze whether the degree of internationalization differs between industries. The dataset covers the CAC40, the DAX30 and the 30 largest firms in the FTSE100 as blue-chip indices and the CAC Next 20 and CAC Mid 60, the MDAX and TecDAX, and the remaining 70 companies in the FTSE100 as mid-cap indices. The comparison of blue-chip and mid-cap indices is based on three indicators of internationalization: percentages of employees based outside the firms’ home country, percentages of foreign sales, and percentages of foreign corporate tax payments. Blue-chip and mid-cap indices exhibit high levels of internationalization. Internationalization is stronger in German and UK blue-chip indices than in these countries’ mid-cap indices, whereas internationalization in French mid-cap and blue-chip indices is similar. Blue-chip and mid-cap firms in the energy/materials/utilities and industrials sectors exhibit similar levels of internationalization, whereas blue-chip firms in the consumer and health sectors exhibit higher levels than corresponding mid-cap firms. The research question and results are of particular importance for retail and institutional investors, because investing in indices typically represents a low cost alternative to individual stock picking. The question whether stock index characteristics, such as market capitalization and industry, influence the degree of international diversification within the index is largely unanswered in the literature. The paper addresses this question.     

Merger policy and tax competition: the role of foreign firm ownership

In many situations, governments have sector-specific tax and regulation policies at their disposal to influence the market outcome after a national or an international merger has taken place. In this paper we study the implications for merger policy when countries non-cooperatively deploy production-based taxes and firms may be partly owned by foreigners. We find that when foreign firm ownership is low in the pre-merger situation, non-cooperative tax policies are more efficient after a national merger, and smaller synergy effects are needed for this type of merger to be proposed and cleared. In contrast, cross-border mergers dominate when the degree of foreign firm ownership is high initially. These results suggest a link between increasing international portfolio diversification and the rising share of cross-border mergers.
