Partial equilibria with convex capital requirements: existence,uniqueness and stability

We consider several risk-averse financial agents who negotiate the price of a bundle of contingent claims in an incomplete semimartingale model of a financial market. Assuming that the agents’ risk preferences are modeled by convex capital requirements, we define and analyze their demand functions and propose a notion of a partial equilibrium price. In addition to sufficient conditions for the existence and uniqueness, we also show that the equilibrium prices are stable with respect to misspecifications of agents’ risk preferences.     

Book review article In search of an alternative theory: a critique of Dosi et al.'s Technical change and economic theory

In this article the author discusses the main contributions and controversial issues raised in an important bookTechnical change and economic theory. The book represents a cornerstone in theorizing technical change. The main features of the book are summarized and the author discusses a number of controversial issues, such as: the evolutionary perspective; the notion of a technoeconomic paradigm; the analysis of firms' technological behaviour; the notion of institutions; the problem of ‘catching up’ in technology; the treatment of formal modelling and policy implications; and treatment of social aspects of technical change. The author concludes that the book should be treated as a work in progress and not as a fully developed and comprehensive approach. However, the critical mass of findings, gathered in this book, is important reading, and represents an important step forward in the exploration of a new approach to economic theory.     

Monetary policy transmission mechanisms in Serbia: evidence from the fully-fledged inflation targeting regime

This article examines the effectiveness of monetary transmission mechanisms in the Serbian economy, covering the period from January 2009 (the point at which the formal switch to the fully-fledged inflation targeting regime was made) to December 2013. The results of the recursive VAR models suggest that the exchange rate and credit channels play a major role in the monetary transmission process, whereas this is not true in the case of the interest rate channel. However, the results of the non-recursive VAR models show that the role of the exchange rate has diminished over time. On the other hand, the credit channel has become much more influential. Thus, if one of the overriding objectives of adopting the explicit inflation targeting regime is to enhance the importance of other channels apart from the exchange rate channel, which could make monetary policy more effective in achieving price and financial stability, the switch to the inflation targeting regime is justified.     

Sources of productivity differentials in manufacturing in post-transition urban South-East Europe

The paper analyses the effects of urbanization and localisation economies on manufacturing firms’ productivity across urban landscapes in post-transition South-East European (SEE) countries. Fixed-effects panel data estimations on a large sample of firms show that the factors accounting for productivity advantages of manufacturing firms in urban post-transition SEE are related to the firms and to the environment in which these firms operate. Firms located in diversified cities benefit from a productivity premium generated in this type of agglomeration, while no evidence was found that the relative specialization across industries has any effect on firm productivity levels.     

ON AGENT’S AGREEMENT AND PARTIAL‐EQUILIBRIUM PRICING IN INCOMPLETE MARKETS

We consider two risk‐averse financial agents who negotiate the price of an illiquid indivisible contingent claim in an incomplete semimartingale market environment. Under the assumption that the agents are exponential utility maximizers with nontraded random endowments, we provide necessary and sufficient conditions for negotiation to be successful, i.e., for the trade to occur. We also study the asymptotic case where the size of the claim is small compared to the random endowments and we give a full characterization in this case. Finally, we study a partial‐equilibrium problem for a bundle of divisible claims and establish existence and uniqueness. A number of technical results on conditional indifference prices is provided.     

Logic of Aid in an Intertemporal Setting

The paper studies the welfare implications of temporary foreign aid in the context of a simple two‐country model of trade. In addition to its usual effects, a transfer of income in one period is assumed to influence the preferences of the recipient country in the following period. The implied changes in the terms of trade over the two periods are consistent with a number of possible outcomes with respect to the intertemporal welfare of the donor, the recipient, and the world as a whole. Particular attention is devoted to the conditions for strict Pareto improvement and the circumstances under which temporary aid transactions are likely to occur.     

On optimal choice of order statistics in large samples for the construction of confidence regions for the location and scale

Given a large sample from a location-scale population we estimate the unknown parameters by means of confidence regions constructed on the basis of two order statistics. The problem of the best choice of those statistics to obtain good estimates, as $n\rightarrow \infty ,$ is considered.     

Patient care,satisfaction and service quality in health care

It is becoming increasingly important in the healthcare setting to treat patients as consumers and measure their satisfaction with medical services rendered. As such, patient satisfaction should be considered an important output of a country's healthcare system, basically reflecting the stage of its development. The conducted study tested students’ satisfaction with the quality of service provided by student polyclinics. In particular, the study has analysed the impacts of personal relationships, promptness and tangibility on student satisfaction. The findings imply that all three factors significantly affect patient satisfaction, with personal relationships having the strongest impact. Such results suggest that healthcare providers should encourage their doctors to devote more time to their patients and show genuine concern for patients’ problems if they wish to improve overall satisfaction of their patients with the delivered services.     

Enforcement Activity in Consumer Protection Regulation in Croatia

The law regulating consumer protection in the Republic of Croatia began its intensive development through the process of harmonization of Croatian legislation with EU law. Apart from the approximation of Croatian legislation with the acquis, in the pre-accession process, Croatia also undertook obligations to introduce and develop corresponding mechanisms for the efficient enforcement of consumer protection in practice. The development of consumer protection policy was recognized as a priority area in Croatia, and even before full membership, the process of implementing new directives in the area of consumer protection ran almost in parallel to and at the same pace as that of the Member States. Alongside the harmonization of its legislation with the EU consumer acquis, Croatia started developing a regulatory enforcement structure, including a whole series of mechanisms to achieve individual and collective protection of consumer rights. Among other things, the satisfactory development of regulatory enforcement activities in consumer protection was one of the preconditions for the successful completion of the accession negotiations and for signing the accession treaty. At the same time, the article suggests that in the area of both the individual and collective realization of consumer protection, there is a need for further progress through, on the one hand, developing administrative capacities and enhancing access to justice, as well as developing a system of out-of-court settlement of consumer disputes on the other.
