Kommunikation von Innovationen — Marketing und PR als „Spielmacher“

Zusammenfassung  Im Innovationsprozess, bei dem Kunden, Mitarbeiter und andere Stakeholder frühzeitig eingebunden werden, bekommen auch Marketing- und PR-Verantwortliche neue Aufgaben. über Kreativit?t, Vermittlungskompetenz und Medien-Know-how hinaus sind neue F?higkeiten und Rollenbilder gefragt. Als besonders geeignet für die ver?nderten Anforderungen haben die Autoren die Strategie der „Spielmacher“ identifiziert. Lesen Sie, was diese Strategie auszeichnet, welche Rollen Kommunikationsabteilungen im Innovationsprozess übernehmen und wie das in der Praxis aussieht.     

Participation by U.S. Agencies in International Brand Advertising: An Empirical Study

Abstract

Marry ad agency executives have proclaimed the era of the global advertising agency. They observe that corporations are moving towards placement of their worldwide advertising through a single agency, and they predict that a few large “mega-agencies” will take over a majority of international advertising accounts. Yet, no published studies have examined how many brands are actually handled by the same ad agency worldwide. This paper presents the results of a survey examining the extent to which U.S. companies use the same agency to advertise abroad and in the home market. The study found that of the brands sold abroad, only about one-third are handled by the same agency both at home and abroad. This proportion does not vary significantly with advertising budgets, by product class, or between standardized and non-standardized brands. In addition, no single-agency group or “mega-agency” handles more than eight percent of the sample brands, and no agency handles a majority of its U.S. brands abroad.     

Copula Gaussian graphical models with penalized ascent Monte Carlo EM algorithm

Typical data that arise from surveys, experiments, and observational studies include continuous and discrete variables. In this article, we study the interdependence among a mixed (continuous, count, ordered categorical, and binary) set of variables via graphical models. We propose an ?₁‐penalized extended rank likelihood with an ascent Monte Carlo expectation maximization approach for the copula Gaussian graphical models and establish near conditional independence relations and zero elements of a precision matrix. In particular, we focus on high‐dimensional inference where the number of observations are in the same order or less than the number of variables under consideration. To illustrate how to infer networks for mixed variables through conditional independence, we consider two datasets: one in the area of sports and the other concerning breast cancer.     

„Rettungsprogramme“ für Krisenländer verschärften die Krise — eine Replik

In his reply, Niemeier accuses Boysen Hogrefe and Stolzenburg of erroneously ascribing the failing of the Greek programme to insufficient “ownership”, whereas the true cause is — in his view — an inadequate austerity policy. The alleged success of this policy in Portugal and Ireland refers solely to GDP growth and ignores the continuing high levels of unemployment in those countries. Boysen- Hogrefe and Stolzenburg insist that the “success” of a rescue programme actually implies that the respective country is able to return to capital markets. The Greek crisis was structural rather than cyclical, so a temporary stabilisation of domestic demand (financed by additional foreign debt) would not have solved the issue.     

An investigation of the gains from commitment in monetary policy

We propose a simple framework for analyzing a continuum of monetary policy rules characterized by differing degrees of credibility, in which commitment and discretion become special cases of what we call quasi-commitment. The monetary policy authority is assumed to formulate optimal commitment plans, to be tempted to renege on them, and to succumb to this temptation with a constant exogenous probability known to the private sector. By interpreting this probability as a continuous measure of the (lack of) credibility of the monetary policy authority, we investigate the welfare effect of a marginal increase in credibility. Our main finding is that, in a simple model of the monetary transmission mechanism, most of the gains from commitment accrue at relatively low levels of credibility.

Do Shareholders Vote Strategically? Voting Behavior, Proposal Screening, and Majority Rules

We analyze how shareholders screen management proposals at annualgeneral meetings. First, we use a simple model of strategicvoting to develop a theoretical benchmark of effective informationaggregation through voting. Then, we derive testable implicationsand provide structural estimates of the model parameters. Themain conclusions are that shareholders vote strategically andthat proposal screening increases value. Shareholders largelyneutralize the lock-in effect of supermajority rules, therebypreventing the incorrect rejection of proposals.     

What moves the tail? The determinants of the option‐implied probability density function of the DAX index

In this article a study of the option‐implied probability density function (PDF) of German stock returns is presented. The use of option prices allows for the quantification of the risk‐neutral probability of large movements in the DAX index. Using daily data for the period from December 1995 to May 2002, the mixture of log‐normals specification with a constant maturity of 49 days is estimated. The time series behavior of the option‐implied PDF during episodes of market turbulence is discussed at the outset. The main purpose of the study is to consider the relationship of summary measures of the option‐implied PDF to macroeconomic news, information from the U.S. stock market, and risk premia. The results suggest the existence of a significant spillover from the U.S. stock market. Returns and the volatility of U.S. stock prices have a strong effect on changes in the lower DAX tail probability, but also on the higher moments of the option‐implied PDF. © 2005 Wiley Periodicals, Inc.
