Mars or Mercury redux: The geopolitics of bilateral trade agreements

We analyse the role of economic and security considerations in bilateral trade agreements. We use the pre‐World War I period to test whether trade agreements are governed by standard gravity variables, or by instead—or in addition—geopolitical factors. While we like others find support for standard gravity variables, we also find that defence pacts boost the probability of trade agreements by as much as 20 percentage points. Our estimates imply that were the U.S. to alienate its geopolitical allies, the likelihood and benefits of successful bilateral agreements would fall significantly. Trade creation from an agreement between the U.S. and E.U. countries would decline by about 0.6 per cent of total U.S. exports.     

Reasoning under uncertainty and multi-criteria decision making in data privacy

By means of an integration of decision theory and probabilistic models, we explore and develop methods for improving data privacy. Our work encompasses disclosure control tools in statistical databases and privacy requirements prioritization; in particular we propose a Bayesian approach for the on-line auditing in Statistical Databases and Pairwise Comparison Matrices for privacy requirements prioritization. The first approach is illustrated by means of examples in the context of statistical analysis on the census and medical data, where no salary (resp. no medical information), that could be related to a specific employee (resp. patient), must be released; the second approach is illustrated by means of examples, such as an e-voting system and an e-banking service that have to satisfy privacy requirements in addition to functional and security ones. Several fields in the social sciences, economics and engineering will benefit from the advances in this research area: e-voting, e-government, e-commerce, e-banking, e-health, cloud computing and risk management are a few examples of applications for the findings of this research.     

An Exploration of Frequent Service Failures in the Brazilian Airline Industry

This study explores how customer evaluations of service failures and failure recurrence impact negative emotions and intent to complain. A survey of 589 Brazilian airline passengers demonstrates the meditational effect of negative emotions such that customers who perceive failures as severe and/or preventable by the airline develop more negative emotions, which subsequently increases intent to complain. We also demonstrate the moderating role of failure recurrence such that failure recurrence reduces the effect of failure severity on negative emotions. Our findings have important implications for managers and airlines in order to mitigate negative outcomes following a service failure.     

Modeling a Dynamic Portfolio for Pension Plans in Emerging Markets With Myopic and Nonmyopic Behavior

ABSTRACT

We introduce a dynamic formulation for the problem of portfolio selection of pension funds in the absence of a risk-free asset. In emerging markets, a risk-free asset might be unavailable, and the approaches commonly used may no longer be suitable. We use a parametric approach to combine dynamic programming and Monte Carlo simulation to gain additional flexibility. This approach is general in the sense that optimal asset allocation is tractable for all HARA utility functions in the absence of a risk-free asset. The traditional case composed of several risky assets and one risk-free asset is compared to a case in which the risk-free asset is unavailable.     

Cultural Distance and Future Entry Mode Choice of Brazilian MNEs

We analyze the relationship between current cultural distance (CD) and future entry mode choice of Brazilian multinational enterprises (MNEs). We use the GLOBE Project in order to extend the distance literature into the entry mode context. Results demonstrate that high levels of CD have a negative impact on future expansions via acquisition and a positive impact on exporting. These relationships are moderated by size, such that large firms are affected less by CD than small firms. Finally, CD values have a greater impact on future entry mode preference than CD practices.     

Ranking and weak consistency in the A.H.P. context

The actual ranking of a set of alternatives is obtainable in a simple way assuming that the matrixA of pairwise comparisons isr-transilive. We show that, in some cases of inconsistency, the weights assigned to the alternatives by means of some well-known methods, suggested by the A.H.P., do not agree with the ranking. Further we introduce a condition, theweak consistency ofA, that ensures the mentioned methods provide weights according with the ranking.     

Reformulating Arrow’s Conditions in Terms of Cardinal Pairwise Comparison Matrices Defined Over a General Framework

In the paper, we deal with cardinal preferences of experts when these are expressed by means of Pairwise Comparison Matrices (PCMs). In order to obtain general results, suitable for several kinds of PCMs proposed in literature, we focus on PCMs defined over a general unifying framework, that is an Abelian linearly ordered group. In this framework, firstly, we aggregate several PCMs and we analyse how the aggregated PCM preserves some coherence levels, such as transitivity, weak consistency and consistency. Then, we reformulate Arrow’s conditions in terms of PCMs, and we provide two preference aggregation procedures for representing group preferences that give a social PCM and a social cardinal ranking, respectively. Finally, we analyse how these preference aggregation procedures satisfy reformulated Arrow’s conditions.     

You can pick your friends,and you can pick your nodes,but you can't pick your friends' nodes: misattributions of others'

One hundred and eleven managers from international organizations in Hungary selected success factors listed on cards by importance. The expressed preferences of non-Hungarians in this node selection task differed from the preferences attributed to them by the locals; the locals felt that the non-Hungarians did not care enough about the local environment, while the non-Hungarians - by their card selection - appeared to care more than the locals did about those issues. Several candidate explanations for the discrepancy are discussed, but all are eliminated with the exception of misattribution on the part of the locals. Implications of wide-spread misattribution, both for practice and for how management scholars go about their business, are discussed.
