The impact of the meal situation on the consumption of ready meals

The context in which a meal is eaten is known to affect intake and choice of food. The purpose of this study was to investigate in what typical situations ready meals are consumed and if consumer demands vary according to different situations. With a market survey four typical ready meal eating situations were identified, and the respondent's ready meal consumption was shown to be affected by situational factors. In the different eating situations there were dissimilar reasons for consumption. Two ready meal eating situations were investigated in greater detail in order to establish what triggered the ready meal consumption in these situations. One of these meal situations proved to be convenience driven and the other time driven. A situation‐oriented approach is suggested for further ready meal product development.     

Estimating the Impact of Climate Change on Agriculture in Low-Income Countries: Household Level Evidence from the Nile Basin, Ethiopia

This paper presents an empirical analysis of the impact of climate change on agriculture in a typical developing country. The economic implications of climate change are estimated by using both a farm productivity and a Ricardian framework. Data are drawn from about 1,000 farms producing cereal crops in the Nile Basin of Ethiopia. The thin plate spline method of spatial interpolation was used to predict household specific rainfall and temperature values using meteorological station data collected for 30?years across the regions. We found that climate change adaptation has a significant impact on both farm productivity and farm net revenues. We complement the analysis by providing an estimation of the determinants of adaptation. Extension services (both formal and farmer to farmer), as well as access to credit and information on future climate changes are key drivers of adaptation.     

R&D cooperation with scientific institutions: a difference-in-difference approach

Economists and business managers have long been interested in the impact of research and development (R&D) cooperation with scientific institutions on the innovation performance of firms. Recent research identifies a positive correlation between these two variables. This paper aims to contribute to the identification of the relationship between R&D cooperation with scientific institutions and the product and process innovation performance of firms by using a difference-in-difference approach. In doing so, we distinguish between two different types of scientific institutions: universities and governmental research institutes. For the econometric analyses, we use data from the German Community Innovation Survey. In total, data from up to 560 German service and manufacturing firms are available for the difference-in-difference analyses. The results suggest that R&D cooperation with universities and governmental research institutes has a positive effect on both product innovation and process innovation performance of firms.     

The Swedish industrial support program of the 1970s revisited

The economy-wide dynamic cost-benefit study of the Swedish industrial subsidy program 1976 through 1984 (Carlsson et al. Res Policy 10(43):336–354 1981; Carlsson J Ind Econ 32(1):9–14, 1983a, b) is revisited in light of later economic development. Since the Swedish Micro to Macro model (Eliasson Am Econ Rev 67(1):277–281 1977a, 2017a) was used for quantification, this article is both (1) a study on the calibration of high dimensional micro-based and nonlinear economic systems models, and (2) a post inquiry into the empirical credibility of the cost-benefit calculations performed. We find that the Micro-based Macro model represents the minimum of detailed resolution necessary for the dynamic cost benefit calculations of the micro interventions in the Swedish economy we study. Even though the increased model complexity meant significant parameter calibration difficulties, a thoroughly researched model specification with exactly defined policy interfaces (with the markets of the economy) should take priority over parameter estimation problems, and always be preferred to estimating the parameters of a wrongly specified model perfectly. The oil price shocks of the 1970s caused radical market disorder in the western economies, bankrupting some 35% of Swedish manufacturing and threatening the Swedish government with massive unemployment. We confirm the earlier results that the government choice of a radical employment rescue policy came at enormous social cost in the form of economic stagnation, and still did not prevent the unemployment of the rest of OECD Europe from hitting Sweden a decade later, and persisting well into the next millennium. According to an alternative simulated policy scenario on the model, had the subsidies been replaced with a general lowering of the payroll tax of the same magnitude and the consequent increase in unemployment taken immediately during 1976–1980, production structures would have been radically and rapidly reorganized, normal employment would have been rapidly restored, and neither the stagnation nor the radical increase in unemployment of the early 1990s would have occurred. In retrospect we see no reason to worry about the empirical credibility of this computed dynamic trade off between Keynesian demand and Schumpeterian supply effects (caused by resource reallocations and endogenous structural change due to the price change), as we did then. We conclude with certainty that this trade-off would not even have been discovered as a possibility had we used a traditional model that did not embody these micro-macro linkages.     

Technical basis for collective (Group) pensions insurance in Norway — K 1946

I. Introduction.

In 1933 O. Aabakken in this journal ¹ Olav Aabakken: “A New Basis of Calculation for Collective Pensions Insurance in Norway”. 1933. dealt with the collective (group) pensions insurance in Norway and especially with the technical basis — K 1931 — which was adopted in 1931 by the life offices in common for this branch of insurance. This basis was worked out from the experiences since 1917, when collective pensions insurance was introduced in Norway. When the National old-age insurance was introduced in 1936, the life offices adopted some new collective pensions benefits which could be employed in the cases where an adjustment to the National old age insurance was desirable. O. Böe has described the mode of adjustment. ² Olav Böe: “Relations between Collective Pensions Insurance, Employer's Pension Funds and National Insurance in Norway”.

The value of commuting time in an empirical on-the-job search model – an application based on moments from two samples

This article estimates the Value of Commuting Time (VOCT) among Swedish males in an empirical on-the-job search model. It uses a large sample of employee-establishment linked data obtained from administrative registers. The sample lacks information on mode choice for the journey to work. We therefore estimate a mode choice model on another sample and use this model to link the administrative data to the relevant set of travel times, costs and distances. The VOCT is found to be 1.8 times the net hourly wage rate in the sample. The relatively high estimate results from a high VOCT among cohabiting men.     

Attitudinal loyalty and trust in entrepreneurship: building new relationships

This paper studies the impact of attitudinal loyalty and trust in entrepreneurship, following a client-focused strategy. In this context, trust and commitment are the cornerstone of relationship marketing, and contributes positively to achieving attitudinal loyalty, which is suitable for the maintenance of relationships over time. This variable also acts as a facilitator or mediator on the influence satisfaction has on loyalty. We show that satisfaction has a positive impact on trust and attitudinal loyalty. Following structural equation modelling methodology we test all the relationships in a sample composed by travel agency customers.

Forecasting the Adoption of GM Oilseed Rape: Evidence from a Discrete Choice Experiment in Germany

This paper explores farmers’ willingness to adopt genetically modified (GM) oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation reveals that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non‐GM rape varieties. A monopolistic seed price would substantially reduce demand for the new technology. A monopolistic seed supplier would reap between 45% and 80% of the GM rent, and the deadweight loss of the monopoly would range between 15% and 30% of that rent. The remaining rent for farmers may be too small to outweigh possible producer price discounts resulting from the costs of segregating GM and non‐GM oilseed rape along the supply chain.     

GUEST EDITORIAL: Cutting corners in chemical risk limitation

The first genetically modified crops and foods to be approved for commercial use in the European Union have prompted intense controversy. Food retailers and processors have been forced to take up the concerns voiced by their customers. New networks of groups have formed to oppose the technology. In response to these pressures, regulators who approved the products have had to reconsider questions they had previously dismissed or officially resolved. Governments have devised more precautionary measures of various kinds. For example, they have increased the burden of evidence for demonstrating safety, have broadened the practical definition of the ‘adverse effects’ which must be prevented, and have devised marketstage precautions for such effects. These extra measures manage the risk debate as well as any risks. In such ways, the technocratic model of European harmonization is being challenged and superseded. This may allow differences in national practices to be viewed as valuable expert resources for a different harmonization model, rather than as deviations from a universal rational norm. Regulatory conflicts offer precautionary opportunities, which could lead to more flexible and democratic procedures. Theoretical perspectives – on risk, uncertainty, precaution, European integration, expertise and the internal market – help illuminate these possibilities.
