Micromagnetic Simulations of Anisotropies in Coupled and Uncoupled Ferromagnetic Nanowire Systems

The influence of a variation of spatial relative orientations onto the coupling dynamics and subsequent magnetic anisotropies was modeled in ferromagnetic nanowires. The wires were analyzed in the most elementary configurations, thus, arranged in pairs perpendicular to each other, leading to one-dimensional (linear) and zero-dimensional (point-like) coupling. Different distances within each elementary pair of wires and between the pairs give rise to varying interactions between parallel and perpendicular wires, respectively. Simulated coercivities show an exchange of easy and hard axes for systems with different couplings. Additionally, two of the systems exhibit a unique switching behavior which can be utilized for developing new functionalities

Convergence and anchoring of yield curves in the Euro area

We study the convergence of European bond markets and the anchoring of inflation expectations in euro area countries using high-frequency bond yield data for France, Germany, Italy and Spain. We find that Economic and Monetary Union (EMU) has led to substantial convergence in euro area sovereign bond markets in terms of interest rate levels, unconditional daily fluctuations, and conditional responses to major macroeconomic data announcements. Our findings also suggest a substantial increase in the anchoring of long-term inflation expectations since EMU, particularly for Italy and Spain, which since monetary union have seen their long-term interest rates become much lower, much less volatile, and much better anchored in response to news. Finally, the reaction of far-ahead forward interest rates to macroeconomic announcements has converged substantially across euro area countries and even been eliminated over time, thus underlining not only market integration but also the credibility that financial markets attach to monetary policy in the euro area.Bond market

Governance and strategy of entrepreneurial networks: an introduction

This special issue focuses on empirical and theoretical papers that help us to better understand the strategy and governance of entrepreneurial networks, such as franchise chains, alliances, and cooperative networks. The following central themes are covered: (I) Which formal governance mechanisms do entrepreneurial networks use in order to reduce transaction cost/agency cost and to increase strategic value? (II) What is the role of relational governance mechanisms (such as information exchange and social ties) for the performance outcomes in franchise chains and cooperatives? (III) Which alliance strategies do entrepreneurial firms pursue to realize a competitive advantage, and what is the impact of resources and capabilities on performance outcomes of entrepreneurial firms. To address these issues, insights from organizational economics (transaction cost theory, agency theory, signaling theory), strategic management perspectives (resource-based, knowledge-based and organizational capabilities theory), entrepreneurship theory and the relational governance view are used

Firms' investment under financial constraints: a Euro area investigation

In this paper we describe a model of optimal investment of various types of financially constrained firms. We show that the resulting relationship between internal funds and investment is non-monotonic. In particular, the magnitude of the cash flow sensitivity of the investment is lower for firms with credit rationing compared to firms that are able to obtained short-term external financing. The inverse relationship is driven by the leverage multiplier effect. A positive cash flow shock increases the short-term borrowing capacity of the firm, which in turn has a positive effect on investment and firm's growth. Moreover, the leverage multiplier effect is the highest for firms relying on short-term credits and it is lower for firms that are able to obtain long-term financing. Analysing a large euro area data set we find strong empirical support for our theoretical predictions. The results also help to explain some contrasting findings in the financial constraints literature
