STABILITY OF THE UTILITY MAXIMIZATION PROBLEM WITH RANDOM ENDOWMENT IN INCOMPLETE MARKETS

We perform a stability analysis for the utility maximization problem in a general semimartingale model where both liquid and illiquid assets (random endowments) are present. Small misspecifications of preferences (as modeled via expected utility), as well as views of the world or the market model (as modeled via subjective probabilities) are considered. Simple sufficient conditions are given for the problem to be well posed, in the sense that the optimal wealth and the marginal utility‐based prices are continuous functionals of preferences and probabilistic views.     

Contribution of financial market segments at different stages of development: Transition,cohesion and mature economies compared

What is the impact of financial sector segments at different stages of development? We apply a production function approach to investigate the impact of the credit, bond and stock segments in nine EU-accession countries over early years of transition (1996–2000) and compare these to mature market economies and to countries at intermediate stage. We find that the transfer mechanisms differ over the development cycle (from bond markets to educational attainment to labor participation) and that financial market segments with links to the public sector (but not stock markets) contributed to stability and growth in transition economies.     

Viral Marketing in the Food Industry: Canada vs. Serbia

The authors explore the application of viral marketing in the food industry in Canada (as a representative of a high-income country) vs. Serbia (a middle-income country). A theoretical background on the scope of viral marketing is given at the beginning. The initial secondary research pointed out that there was a great number of viral marketing campaigns in the food industry, in both high- and middle-income countries. The primary research showed a high degree of use of viral marketing in the food industry in general, as well as a number of similarities between the two countries. Positive experiences with viral marketing in the food industry were far more common than negative experiences. Most marketing professionals, in both countries, believed that a viral marketing program would benefit their company, and they planned to run a viral marketing campaign again in the future.     

Inflation in New EU Member States: A Domestically or Externally Driven Phenomenon?

This article empirically analyzes the domestic and external inflation determinants for eight non-eurozone new EU member states (NMS), using a structural vector autoregression model. Results indicate that foreign shocks are a major factor in explaining inflation dynamics in the medium run, while the short-run inflation dynamics are mainly influenced by domestic shocks. Moreover, the importance of the foreign inflation component has had a rising trend in the precrisis period in all NMS and mostly coincided with their accession to the EU. This trend ended with the onset of the global financial crisis. The study implicates the need to augment the classical Taylor rule with foreign factors in the case of small open economies.     

Monetary and commercial policy in a two-country flexible exchange rate model with perfect capital mobility

A two-country portfolio-balance model is developed in this paper in order to analyse the international transmission of monetary and commercial policy disturbances under a flexible exchange rate regime. Particular emphasis is placed on the role of capital mobility, differences in the asset demand functions across countries, and national net-asset positions in determining the effects of these policies on the macroeconomic variables of the two countries. Both the short and the long-run effects are considered with expectations assumed to be formed rationally.     

The model based on the matrix of economic growth

This paper is concerned with some aspects of direct and indirect growth rates of sectors and with the model based on the matrix of economic growth. The purpose of this consideration is to determine through indirect growth rates the growth structure of economy and to construct the model which may be used for the planning goals. In other words, by means of the matrix of growth or the model which is based on it we can estimate the future development of the economy. This can be done under different assumptions no matter whether relations are transfered from the past into the future or whether various relations change in future periods on the basis of streamlined elements of the plan. Hence, it can be determined either from the assumption that past relations will be kept approximately in the same frames, or that they will change in the future. In each case all the changes can be described through direct and indirect growth rates.     

Fed funds futures variance futures

We develop a novel contract design, the fed funds futures (FFF) variance futures, which reflects the expected realized basis point variance of an underlying FFF rate. The valuation of short-term FFF variance futures is completely model-independent in a general setting that includes the cases where the underlying FFF rate exhibits jumps and where the realized variance is computed by sampling the FFF rate discretely. The valuation of longer-term FFF variance futures is subject to an approximation error which we quantify and show is negligible. We also provide an illustrative example of the practical valuation and use of the FFF variance futures contract.     

Consumers’ Sensorical Product Evaluation and Perception

The aim of the research was to determine consumer perceptions of meat products regarding their origin and the potential impact of their origin on the sensory evaluation of other meat properties. Data were collected during the experiment. By testing the correlation model with multiple analyses of variance for repeated measures, it was determined that there was a statistically significant correlation between the factors. The important contribution of the research is the surveyed issue and the approach to researching the impact of product origin on scientific field of marketing and field of consumer behavior. The research represents a deeper investigation of impact of country-of-origin (COO) on consumer perceptions. An integrated approach to the research of the impact of meat origin was chosen to form interlinks between meat origin and its other sensorical properties.     

Drivers of productivity in Vietnamese SMEs: the role of management standards and innovation

Using a rich panel dataset of small and medium scale manufacturing enterprises (SMEs) active in the manufacturing sector in Viet Nam, this paper investigates the drivers of firm productivity, focusing on the role played by international management standards certification. We test the hypothesis that, accounting for technological innovation (product and process) and other variables related to technological capabilities, international standards are conducive to higher productivity, through improved management practices and business organization. In line with the requirement of continuous improvement implied by most international standards, the main findings show that the possession of an internationally recognized standard certificate leads to significant productivity premium. We further find that the effect of certification on productivity is particularly strong for firms with technological innovation, located in southern provinces, and operating in more scale-intensive industries.     

Methods of Partial Hedging

In this article we survey methods of dealing with the following problem: A financial agent is trying to hedge a claim C, without having enough initial capital to perform a perfect (super) replication. In particular, we describe results for minimizing the expected loss of hedging the claim C both in complete and incomplete continuous-time financial market models, and for maximizing the probability of perfect hedge in complete markets and markets with partial information. In these cases, the optimal strategy is in the form of a binary option on C, depending on the Radon-Nikodym derivative of the equivalent martingale measure which is optimal for a corresponding dual problem. We also present results on dynamic measures for the risk associated with the liability C, defined as the supremum over different scenarios of the minimal expected loss of hedging C.
