Temperatures,cleanliness and food storage practises in domestic refrigerators in Serbia,Belgrade

Consumers’ knowledge about proper household practises during food handling and storage are deemed insufficient. Therefore, the aim of our study was to investigate the conditions of food storage in refrigerators (temperature, hygienic and storage conditions) and consumer knowledge about good practises. This study included 100 households from the Belgrade area. All participants were interviewed using a standardized questionnaire. The internal temperature of refrigerators was measured at three points: the top and bottom shelves and the refrigerator door. The average temperature in the refrigerators was 9.3°C. The average temperature recorded in the refrigerator doors was significantly higher (P < 0.01) than temperatures recorded on the top or bottom shelves. The age and design of refrigerators, and potential heat source near refrigerator can impact the refrigerator temperature. In 50% of the surveyed refrigerators, food storage practises were incorrect. More than a half (56%) of the surveyed consumers were aware of the recommended refrigerator temperature, but measured temperature in their refrigerators was considerably higher. The results from our study indicate that knowledge of recommended behaviour about good food safety practise do not always translate into practise in the home.     

Website Communication and Business Relationships – Matches and Mismatches

Drawing upon the interaction approach, the internet marketing literature, and qualitative case studies, the paper depicts website communication strategies that match and mismatch different stages of business-to-business relationships. To achieve the match, the more the relationship is developed, the more individualized website communication should be employed. Mismatch situations that hinder a relationship can occur not only when websites are underdeveloped but also when websites are overdeveloped and too individualized, falling short to utilize sellers’ investments.     

Notes on the producer society

Summary The author criticizes economists for their uncritical acceptance of consumers’ revealed preference and tries to explain the preferences manifest in the United States by tracing them to cultural influences, especially the Puritan Ethic, and to economic factors, such as producers’ domination and economies of scale. Differences between American and European behavior patterns are sought mainly in comparative time budgets and Hawtrey’s distinction between defensive and creative consumption is revived as a framework suitable for such analysis. These notes constitute an early version of what has since become a much more ambitious work with a more analytical approach, trying to use behavioral psychology to fill in gaps in the economist’s understanding of consumer behavior, and to be published as a book.     

Simulation Monte Carlo methods in extended stochastic volatility models

A new technique for nonlinear state and parameter estimation of discrete time stochastic volatility models is developed. Algorithms of Gibbs sampler and simulation filters are used to construct a simulation tool that reflects both inherent model variability and parameter uncertainty. The proposed chain converges to equilibrium enabling the estimation of unobserved volatilities and unknown model parameter distributions. The estimation algorithm is illustrated using numerical examples. Copyright © 2002 John Wiley & Sons, Ltd.

The Role and Current Status of IFRS in the Completion of National Accounting Rules – Evidence from Slovenia

Abstract

We provide an overview of the role and current status of International Financial Reporting Standards (IFRS) in the development of national accounting rules in Slovenia. The basic requirements of the financial reporting in Slovenia are set in the Companies Act, while the Slovenian accounting standards (SAS) provide a detailed authoritative guidance, especially on measurement. We describe the (historical) relations of all four editions of SAS with IFRS, provide explanations for the close alignment of SAS 2006 and SAS 2016 with IFRS, and identify major differences. In addition, the paper covers the adoption of the new EU accounting Directive into Slovenian legislation.     

Writing Clearly: The ECB's Monetary Policy Communication

The article presents a novel methodology for measuring the clarity of central bank communication using content analysis, illustrating the methodology with the case of the European Central Bank (ECB). The analysis identifies the ECB's written communication as clear in about 85–95% of instances, which is comparable with, or better than, similar results available for other central banks. We also find that the additional information on risk to inflation and especially projection risk assessment contained in the ECB's Monthly Bulletins helps to improve communication clarity compared to ECB's press releases. In contrast, the bulletin's communication on monetary developments has a negative, albeit small, impact on clarity.     

Developing countries in competition for foreign investment

This study analyzes the competition for foreign direct investment (FDI) among countries at different stages of development. It is assumed that domestic companies in a more-developed country use more capital in production and that wages in a less-developed country are lower. Countries can compete for FDI by increasing the supply of public inputs in the economy, in addition to (or instead of) offering subsidies or tax reliefs to foreign investors. The results reveal that if governments of competing countries are not allowed to discriminate between domestic and foreign firms, there may be situations in which a less-developed economy will attract FDI depending on the labor cost differential and the responsiveness of foreign investor's and domestic companies' output to changes in the supply of public inputs. If tax discrimination between domestic and foreign firms is permitted, both countries will optimally raise the supply of public inputs, but the more-developed country will always win the foreign investment despite higher labor costs. Thus, governments of less-developed countries may have an incentive to work on an international agreement to disallow tax discrimination.     

An improved convolution algorithm for discretely sampled Asian options

We suggest an improved FFT pricing algorithm for discretely sampled Asian options with general independently distributed returns in the underlying. Our work complements the studies of Carverhill and Clewlow [Risk, 1990, 3(4), 25–29], Benhamou [J. Comput. Finance, 2002, 6(1), 49–68], and Fusai and Meucci [J. Bank. Finance, 2008, 32(10), 2076–2088], and, if we restrict our attention only to log-normally distributed returns, also Ve?e? [Risk, 2002, 15(6), 113–116]. While the existing convolution algorithms compute the density of the underlying state variable by moving forward on a suitably defined state space grid, our new algorithm uses backward price convolution, which resembles classical lattice pricing algorithms. For the first time in the literature we provide an analytical upper bound for the pricing error caused by the truncation of the state space grid and by the curtailment of the integration range. We highlight the benefits of the new scheme and benchmark its performance against existing finite difference, Monte Carlo, and forward density convolution algorithms.
