14. Postscript on social change

The major weakness of the world dynamics models is that they illustrate the pessimistic consequences of exponential growth in a finite world without taking account of politics, social structure, and human needs and wants. The introduction of an extra variable—man—into thinking about the world and its future may entirely change the structure of the debate which these models have so far limited to physical properties.     

Harmonization of financial reporting of small and medium-sized enterprises in the Czech Republic

A current problem of the present-day accounting and financial reporting consists in aligning the accounting in small and medium enterprises. In July 2009 the International Financial Reporting Standard for small and medium-sized enterprises was issued, which extended the aligning possibilities also to small and medium enterprises considerably. If the standard is adopted by the national legislation, problems connected with the standard implementation in the national legislation will have to be solved as well as practical issues connected with making financial statements. At present the yields and the problems which can arise in connection with the standard application have to be focused on. A contribution of the standard application will be a better informative ability of financial statements on the international level. At small and medium enterprises this can contribute to better comanunication with banks, with investors, rating application are： parallel reporting according to national agencies etc. The problems connected with the standard regulations, differences between the national legislation and the standard, wide practice at keeping accounts and making financial statements and limited approach of small and medium enterprises to obtaining information and to training of their employees. Another problem can be a tight link between the trading income and the tax base, when small companies prefer rather the tax point of view.     

Consumer Socialization and the Role of Branding in Hazardous Adolescent Drinking

This study examines the relationship between alcohol marketing and consumer socialization to alcohol brands (assessed here using aided and unaided brand recognition and brand saliency), and the associated relationship between consumer socialization and hazardous alcohol consumption among a cohort of adolescents surveyed in Scotland. The research addresses gaps in the consumer socialization literature, by examining how marketing influences brand consumer socialization, and how brand consumer socialization influences subsequent hazardous consumption behavior over time, using a robust longitudinal design that assesses causal relationships while controlling for a wide range of important confounding variables. The results demonstrate the contribution of marketing to adolescents’ brand socialization to alcohol and the impact of this socialization on subsequent drinking behaviors. Implications for marketing managers, parents, policymakers, and consumer researchers are discussed, together with suggestions for future consumer research.     

Production planning and inventories optimization: A backward approach in the convex storage cost case

We study the deterministic optimization problem of a profit-maximizing firm which plans its sales/production schedule. The firm controls both its production and sales rates and knows the revenue associated to a given level of sales, as well as its production and storage costs. The revenue and the production cost are assumed to be respectively concave and convex. In Chazal et al. [Chazal, M., Jouini, E., Tahraoui, R., 2003. Production planning and inventories optimization with a general storage cost function. Nonlinear Analysis 54, 1365–1395], we provide an existence result and derive some necessary conditions of optimality. Here, we further assume that the storage cost is convex. This allows us to relate the optimal planning problem to the study of a backward integro-differential equation, from which we obtain an explicit construction of the optimal plan.     

The Effects of Trade Liberalization between Heterogeneous Countries on Endogenous Mergers

This paper examines the effects of trade liberalization on merger behavior. We endogenize merger choice among owners in an oligopolistic industry in asymmetric countries to analyze the consequences of trade cost reductions on competitiveness and welfare. In this context, the non‐cooperative game supports asymmetric market structures. We also find that trade liberalization is not necessarily pro‐competitive in countries with the competitive advantage, even if trade costs are completely abolished. Moreover, the tariff‐jumping explanation of international mergers does not necessarily apply. The welfare analysis shows that merger behavior can significantly alter any gains from liberalization. Countries should consider enforcing competition in regional agreements. Specifically, to avoid a reduction in domestic welfare following trade‐liberalizing reductions in trade costs, a high‐cost country's optimal policy may be to ban international mergers.     

Do Inflation‐Linked Bonds Still Diversify?

The diversifying power of inflation-linked (IL) bonds relative to traditional asset classes has changed significantly. In this paper, we study the dynamics of conditional volatilities and correlations for three asset classes, IL bonds, nominal bonds and equities, in the USA and Europe. Using a DCC-MVGARCH for the period 1997–2007, we highlight the change that took place in 2003. Although IL bonds once had definite diversification power, they are now highly correlated with nominal bonds and have reached similar volatility levels. As a result, the two asset classes are practically substitutable. This seems to be due to more stable inflation expectations and to a more liquid IL bond market. Although diversification was a valuable reason for introducing IL bonds in a global portfolio before 2003, this is no longer the case. Dynamic portfolio optimisation using our estimates of conditional correlations and volatilities clearly demonstrates that the optimal weight of IL bonds in a portfolio decreased sharply in 2003 in favour of nominal bonds and equities.     

Strategic individual assessment: Issues in providing reliable descriptions

Individual assessment involves one psychologist making an assessment of an individual for personnel-related purposes. Individual assessment practice is reviewed, and research on reliability is presented. A study examining the comparability of conclusions reached by consumers is presented. Eighty-six students and thirty-eight managers read nine narrative assessment reports (three of each of three job candidates) and attempted to determine which reports described the same candidate. None of the subjects could correctly group the nine reports; a sizeable proportion did no better than chance in grouping the reports. Implications for assessors and consumers of individual assessments are discussed.
