Incorporating Discontinuous Preferences into the Analysis of Discrete Choice Experiments

Data from a discrete choice experiment on improvements of rural landscape attributes are used to investigate the implications of discontinuous preferences on willingness to pay estimates. Using a multinomial error component logit model, we explore differences in scale and unexplained variance between respondents with discontinuous and continuous preferences and condition taste intensities on whether or not each attribute was considered by the respondent during the evaluation of alternatives. Results suggest that significant improvements in model performance can be achieved when discontinuous preferences are accommodated in the econometric specification, and that the magnitude and robustness of the willingness to pay estimates are sensitive to discontinuous preferences.     

Central government accounting harmonization in EU member states: will EPSAS be enough?

A highly controversial topic in the EU is the need for harmonized accrual-based standards to improve the quality of public accounts and reduce differences (adjustments) between the micro-(governmental accounting) and macro- (national accounting) levels. This paper shows that a set of high-quality accounting standards, like the future EPSAS, are not going to be sufficient to overcome the present lack of harmonization. The authors explain why this is the case having researched accounting data from 28 EU member states.     

Measuring Innovation in European Industry

This paper analyses the results of the 1993 Community Innovation Survey (CIS). Fifty per cent of European firms introduced a product or process innovation during 1990-92. The share of innovating firms varies between industrial sectors and firm size. The percentage of innovating firms is higher for large firms than for smaller ones. In high-tech sectors this share is two thirds and for traditional ones is one third. The largest part of firms' expenditure for innovation is linked to the adoption and diffusion of technologies through machinery and equipment, which absorbs 50% of firms' innovation expenditure. R&D activities represent, on average, 20% of total innovation expenditure while other innovative activities, such as design and trial production, account respectively for 10% and 11%. The mix of innovation inputs, especially R&D and investment, is strongly correlated with firm size, displays little change across countries and varies greatly across industries.     

Cost thresholds,cut-offs and sensitivities in stated choice analysis: Identification and implications

Within the discrete choice literature, there is growing recognition that some respondents do not process all attributes when evaluating their choice outcomes. Worryingly, the cost attribute is often among those attributes that are likely to be ignored by respondents. We use probabilistic decision process models (similar in form to latent class models, but where we define the classes to describe specific heuristics) to facilitate situations where respondents adopt cost thresholds and cut-offs. We further develop this model to address the potential confounding between preference heterogeneity and processing heterogeneity by simultaneously allowing for a segmentation of respondents based on their sensitivities to cost. Results, based on an empirical dataset on the existence value of rare fish species in Ireland, provide further confirmation that a share of respondents did not attended to cost. Importantly, however, when heterogeneity to cost levels is accounted for the inferred incidence of complete non-attendance is markedly lower, to the extent that when cost thresholds and cut-offs are also accommodated it almost disappears. This modelling approach leads to significant gains in model fit and has important implications for welfare analysis.     

THE DIVERSITY OF ACCRUAL POLICIES IN LOCAL GOVERNMENT FINANCIAL REPORTING: AN EXAMINATION OF INFRASTRUCTURE,ART AND HERITAGE ASSETS IN GERMANY,ITALY AND THE UK

This paper examines the norms and practices for infrastructure, art and heritage assets in six cities, across three European countries, to determine how the national norms of accrual accounting compared with each other, and with IPSAS, and how the practices in each city compared with the norms. We identify significant diversity between actual practices and the norms imposed by national policy‐makers or set by IPSAS. Given that a longstanding concern of the literature has been on whether these kinds of assets should be included in governmental balance sheets and operating statements at all, it is striking how often the question was settled in practice by excluding art and heritage assets, even when this meant non‐compliance with national norms. In our three countries, it is clear that comparability of the financial statements between countries was not a concern of policy‐makers, and comparability between cities within each country not a concern of preparers.     

Dispersed initial ownership and the efficiency of the stock market under moral hazard

We generalize a standard general equilibrium framework extended for moral hazard to allow for a dispersed initial ownership distribution of firms. We show that the market allocation is constrained-efficient only when in each firm the entrepreneur who generates payoffs through unobservable effort has full initial ownership in his firm.     

Country-of-Origin Effects on Russian Wine Consumers

In recent years, Russia has experienced significant economic growth. The wine industry is among those most affected by increases in disposable income. As a consequence, Russian wine importers have widened the range at the upper end of the quality spectrum. In the current scenario, some key questions arise concerning consumer attitudes toward wine and the way it is perceived in this evolving market. This article attempts to investigate such concerns through a choice experiment approach conducted by means of a questionnaire-based survey submitted to 388 Russian households located in the country's three largest cities (Moscow, Saint Petersburg, and Novosibirsk). In the experiment, respondents were asked to choose their favorite wine among seven dry red wines. The stated choices are analyzed using a random utility model to obtain an estimation of the price effect through a triangular distribution. Our results indicate the presence of three distinct market segments in the Russian wine market: a segment with only high-quality, highly priced Italian and French wines, a medium-quality segment currently limited to Spanish wines, and a much lower quality segment of wines in which demand for alcohol is essentially satisfied.
