Euromind‐ : A Density Estimate of Monthly Gross Domestic Product for the Euro Area

EuroMInd‐ is a density estimate of monthly gross domestic product (GDP) constructed according to a bottom‐up approach, pooling the density estimates of 11 GDP components, by output and expenditure type. The components' density estimates are obtained from a medium‐size dynamic factor model handling mixed frequencies of observation and ragged‐edged data structures. They reflect both parameter and filtering uncertainty and are obtained by implementing a bootstrap algorithm for simulating from the distribution of the maximum likelihood estimators of the model parameters, and conditional simulation filters for simulating from the predictive distribution of GDP. Both algorithms process the data sequentially as they become available in real time. The GDP density estimates for the output and expenditure approach are combined using alternative weighting schemes and evaluated with different tests based on the probability integral transform and by applying scoring rules.

Real wages and the business cycle in Germany

This article establishes stylized facts about the cyclicality of real consumer wages and real producer wages in Germany. As detrending methods, we apply the Beveridge–Nelson decomposition, the Hodrick–Prescott filter, the Baxter–King filter, and the structural time series model. The detrended data are analyzed both in the time domain and in the frequency domain. The great advantage of an analysis in the frequency domain is that it allows to assess the relative importance of particular frequencies for the behavior of real wages. We propose to use the phase angle as a suitable measure to get detailed information about the correlation and the lead–lag behavior of real wages relative to GDP at different frequencies. In the time domain, we find that both real wages display a procyclical pattern and lag behind the business cycle. In the frequency domain, the consumer real wage lags behind the business cycle and shows an anticyclical behavior for shorter time periods, whereas for longer time spans a procyclical behavior can be observed. For the producer real wage, however, the results in the frequency domain remain inconclusive.     

Bidirectional relationship between investor sentiment and excess returns: new evidence from the wavelet perspective

We propose to use the wavelet concept of the phase angle to determine the lead–lag relationship between investor sentiment and excess returns that are related to the bubble component of stock prices. The wavelet phase angle allows for decoupling short- and long-run relations and is additionally capable of identifying time-varying comovement patterns. Based on the monthly S&P500 index and two alternative monthly US sentiment indicators, we find that in the short run (until 3 months), sentiment is leading returns whereas for periods above 3 months the opposite can be observed. Moreover, the initially strong positive relationship becomes less pronounced with increasing time horizon, thereby indicating that the over- or undervaluation in the short run is gradually corrected in the long run.     

Measures for Dealing with Competence and Integrity Violations of Interorganizational Trust at the Corporate and Operating Levels of Organizational Hierarchy

We examine how partners in an interorganizational relationship can repair violated trust, and if that is impossible, how they can preserve the collaborative relationship. We also consider under what circumstances exit from the relationship is the only viable option. We propose that the effectiveness of legalistic and non-legalistic measures in response to a trust violation is a function of the hierarchical level at which the violation occurred (corporate vs. operating), the character of the violation (competence vs. integrity), the frequency and severity with which it occurred, the organizational context in which boundary spanners are embedded, and the degree of dependence between the partners. Based on these factors, we explore how the way in which violation of trust is dealt with at one hierarchical level might affect trust at the other level. Our theoretical model reveals that prior findings on trust repair in inter-personal context may not hold in the interorganizational context.     

A concern about low relative income, and the alignment of utilitarianism with egalitarianism

A utilitarian social planner who maximizes social welfare assigns the available income to those who are most efficient in converting income into utility. However, when individuals are concerned about their income falling behind the incomes of others, the optimal income distribution under utilitarianism is equality of incomes.     

Problematizing international business futures through a ‘critical scenario method’

This paper proposes the need for change in how managers in international business (IB) determine organisational objectives and what criteria they use in addressing complex problems. We propose a move from a largely firm-centric focus; on profit maximization and shareholder value; to a broader societal and environmental view. We see the educational context as the locus for initiating such a shift. However, we see obstacles within the canon of mainstream IB textbooks, with their focus on exposition of normative models of managerial action, illustrated by case studies of successful multinational enterprises (MNEs). Whilst we acknowledge their incorporation of critical issues, we view the lack of substantive critical reflection on the wider implications of IB activity as underpinned by an implicit assumption of the ‘good’ of IB. We posit that the normative structure of mainstream texts militates against students understanding the full range of possible futures for IB practice, and against developing the capability to cope with situations of uncertainty and ambiguity. Seeking to promote a critical pedagogy that accommodates consideration of both mainstream approaches and critical responses to these, we propose one approach to teaching and learning about IB futures that is based upon development of what we term ‘critical scenario method’. This offers a basis for active investigation of complex problems in the ‘real’ world from a range of perspectives, beyond that of profit maximization. We provide a worked, case example of our new method and demonstrate how it will enhance perceptions/understandings of involved and affected actors’ interests and their likely (re)actions as a particular scenario unfolds. The theoretical grounding for this approach is based upon contemporary social science interpretation of the Aristotelian concept of phronēsis, or ‘practical wisdom’.
