Intercultural Discourse Ethics: Testing Trompenaars' and Hampden-Turner's Conclusions about Americans and the French

Are culture driven ethical conflicts apparent in the discourse of the protagonists? A multi-year, multi-cultural study of managers by Trompenaars and Hampden-Turner resulted in two conclusions relevant to business ethics. The first is that intercultural business conflicts can often be traced to a finite set of cultural differences. The second is that enough similarities exist between cultures to provide the grounds for conflict resolution. The research reported here gives credence to their study when applied to an ethical conflict viewed from French and American perspectives.     

INCORPORATING RISK AND AMBIGUITY AVERSION INTO A HYBRID MODEL OF DEFAULT

It is well known that purely structural models of default cannot explain short‐term credit spreads, while purely intensity‐based models lead to completely unpredictable default events. Here we introduce a hybrid model of default, in which a firm enters a “distressed” state once its nontradable credit worthiness index hits a critical level. The distressed firm then defaults upon the next arrival of a Poisson process. To value defaultable bonds and credit default swaps (CDSs), we introduce the concept of robust indifference pricing. This paradigm incorporates both risk aversion and model uncertainty. In robust indifference pricing, the optimization problem is modified to include optimizing over a set of candidate measures, in addition to optimizing over trading strategies, subject to a measure dependent penalty. Using our model and valuation framework, we derive analytical solutions for bond yields and CDS spreads, and find that while ambiguity aversion plays a similar role to risk aversion, it also has distinct effects. In particular, ambiguity aversion allows for significant short‐term spreads.     

In Memory of Michael Watts (November 3, 1950–December 5, 2014)

In an experimental economics simulation, Ukrainian teachers of economics chose free riding responses at a rate similar to those found by Leuthold in an undergraduate class on public economics at the University of Illinois. The authors speculate that those who become academic economists may do so because they have certain insights in deductive logic.     

How Much Did Oil Market Developments Contribute to the 2009 Recession in Germany?

In this paper, we use a structural vector autoregressive model to study the effects of oil market developments on the German economy. We find that higher oil prices are always associated with a decline in private consumption expenditures, but the response of gross domestic product (GDP) crucially depends on the underlying shock. While a disruption in oil supply provokes a recession, positive world demand shocks prompt a temporary increase in exports and investment, which initially outweigh the cutback on consumption. In a counterfactual analysis, we show that the world demand shocks that led to the 2007/2008 oil price rise triggered a delayed 0.8 percent decrease in German GDP in 2009, and therefore notably contributed to the recession of that year.     

Localized Technological Progress And Industry Structure: An Empirical Approach *

Modem innovation theory holds that the choice of production technique and technical porgress are unseparable activities so that technological progress can be described as localized. Based on this conception one has to expect an intra-sectoral firm heterogeneity in the production techniques applied and the technical efficiency achieved which contrasts to the presumption of intra-sectoral homogeneity as suggested by neoclassical theory. For measuring intra-industry heterogeneity an empirical tool is required which does not rest on the assumption of homogeneity, i.e. on a common production function for all firms under consideration. The method which does not require this assumption, Data Envelopment Analysis, is non-parametric, allows for firm-specific production functions and helps to determine differences in both technical efficiency and production technique applied. This tool is introduced in its basic formulation, its main features are discussed on ihe basis of modern innovation theory, and an empirical analysis for the German machinery, electronics and chemical industry is presented.     

Can a margin squeeze indicate the need for deregulation? The case of fixed network voice telephony markets

In the beginning of fixed network liberalisation in Europe in the late 1990s, the main concern of regulators was to lower retail call prices. This was done by introducing wholesale regulation and promoting service-based competition. Some years later, the concern of some regulators turned from too high retail call prices to too low call prices, which might ‘squeeze’ entrants out of the market. This paper looks at a simple model in which this development is explained by increasing competitive pressure from an ‘outside opportunity’, most notably mobile telephony and cable. It is concluded that a margin squeeze is not necessarily used by the incumbent as a device to drive competitors out of the market and to increase market power but can also result from increased inter-modal competition. If this is the case, it is argued that the appropriate response would be deregulation or – under particular circumstances – a switch from cost-oriented access prices to alternatives such as retail-minus or capacity-based interconnection.
