Some Further Results on the Tempered Multistable Approach

This article provides new results on the tempered multistable approach. After a preliminary section recalling the main definitions, we show the correspondence between a series representation and a characteristic function representation for asymmetrical field-based tempered multistable processes and for asymmetrical independent increments tempered multistable processes. We also show that both processes are semimartingales, which is a convenient property in finance. Next, we study the structure of autocorrelations that is conveyed by this approach. Finally, we provide an illustration showing the term structures of Value-at-Risk that can be obtained with this model.     

Optimal Insurance Against Climatic Experience

An optimal insurance contract against a climatic risk is derived in the presence of an uninsurable and dependent aggregate production risk. The optimal design depends on the stochastic dependency between both sources of uncertainty and on the producer's attitude towards risk, especially on his prudent behavior. Rational weather insurance purchasing decisions are also derived. The prudent producer responds to actuarially fair weather insurance by increasing his exposure towards risk.     

Management and Business Research on Commercial Diplomacy: Examining Trends and Themes

This article reviews the literature of commercial diplomacy during the period 1960–2014 from a management angle and is organized around four major themes: (1) government’s export/trade promotion function; (2) institutional/organizational arrangements; (3) managerial roles and activities; and (4) interaction between commercial diplomats and businesses. A complementary quantitative analysis tracing current research trends reveals the emergence of relevant publications at the end of the 1970s and a real increase after 2000. It also confirms the relative scarcity of commercial diplomacy literature focusing on the business and management dimension. Gaps in current literature are identified, and suggestions for further research are presented.     

Testing the martingale difference hypothesis in CO2 emission allowances

This study examines the martingale difference hypothesis (MDH) for the carbon emission allowance market within the European Union Emission Trading Scheme (EU ETS) during the Phase I and the Phase II, using both daily and weekly data over the 2005–2009 period. We analyze the MDH for spot prices negotiated on BlueNext, European Energy Exchange and Nord Pool along with futures prices negotiated on BlueNext and European Climate Exchange, using the new variance ratio tests developed by Kim (2009) and the generalized spectral test proposed by Escanciano and Velasco (2006). For the Phase I, the results show that the spot price changes of these three markets are predictable, suggesting the possibility of abnormal returns through speculation, except during the period April 2006 to October 2006, namely after the compliance break and before the ECs of stricter NAP II. Finally, we find that the CO₂ spot and futures price changes are unpredictable during the Phase II because we failed to reject the MDH based on both daily and weekly data. Thus, these markets are found to be weak-form efficient.     

THE DYNAMIC PROPERTIES OF ALTERNATIVE ASSUMPTIONS ON PRICE ADJUSTMENT IN NEW KEYNESIAN MODELS

This paper presents a classification of the different new Phillips curves existing in the literature as a set of choices based on three assumptions: the choice of the structure of price adjustments (Calvo or Taylor), the presence of backward indexation and the type of price contracts (fixed prices or predetermined prices). The paper suggests study of the dynamic properties of each specification, following different monetary shocks on the growth rate of the money stock. We develop the analytical form of the price dynamics, and we display graphics for the responses of prices, output and inflation. We show that the choice made for each of the three assumptions has a strong influence on the dynamic properties. Notably, the choice of the price structure, while often considered as unimportant, is indeed the most influential choice concerning the dynamic responses of output and inflation.     

Competition,transmission and bank pricing policies: Evidence from Belgian loan and deposit markets

This paper addresses the pass-through from market interest rates to retail bank interest rates. The paper advocates a heterogeneous approach and applies it to the Belgian banking market. A substantial proportion of the heterogeneity in bank pricing policies can be explained by the bank lending channel and the relative market power hypothesis. The results also suggest that the long-term pass-through is typically less than one-for-one, rejecting the completeness hypothesis. While there is no convincing evidence for asymmetry in retail rates, large deviations from equilibrium mark-ups are faster reduced than small deviations. Overall, conditions for corporate loans are more competitive compared to consumer loans. Demand and savings deposits have, by far, the most rigid prices.     

Management Students’ Attitudes Toward Business Ethics: A Comparison Between France and Romania

This study focuses on the differences in the perception of business ethics across two groups of management students from France and Romania (n = 220). Data was collected via the ATBEQ to measure preferences for three business philosophies: Machiavellianism, Social Darwinism, and Moral Objectivism. The results show that Romanian students present more favorable attitudes toward Machiavellianism than French students; whereas, French students valued Social Darwinism and Moral Objectivism more highly. For Machiavellianism and Moral Objectivism the results are consistent with the literature and our hypotheses. However, contrary to our expectations, we find that Social Darwinism is more important in France than Romania. The results indicate that religious practice does not influence preferences for the three business philosophies. In terms of gender differences, women have less favorable attitudes toward Machiavellianism and more favorable attitudes toward Moral Objectivism than men.     

A GENERALIZED OLIGOPOLY MODEL WITH CONJECTURAL VARIATIONS

This paper considers a generalization of the Stackelberg model to cover a T‐stage framework with several leaders and followers who compete on quantities. Assuming a linear demand function and constant marginal costs, we introduce constant conjectural variations in order to capture various structures of competition. First, we characterize the equilibrium market outcome. Second, we study the influence of conjectures on welfare. We notably propose a welfare comparison for six symmetric equilibria. Third, we consider convergence analysis, and we also show that the competitive equilibrium is a consistent oligopoly equilibrium.
