The purpose of this study is to explore the substitute scarcity appeals (unit scarcity or option scarcity) effect on experiential gift’s purchase intention, based on difference in gift attribute (hedonic or utilitarian gift) and difference in the types of givers (close or distant giver), which is a new consideration.

This study was conducted with two experiments and examined four hypotheses in total. These hypotheses were examined using a 2 × 2 between-subjects designs, and a two-factorial covariance analysis was conducted.

Empirical results show that unit scarcity produces greater purchase intention than the option scarcity of close givers. For hedonic gifts, unit scarcity produced greater purchase intention than the option scarcity.

The originality of this study is to explore the substitute scarcity appeals effect on experiential gift’s purchase intention based on different types of givers and different types of gifts. The result serves as the gift marketing strategy of online platform operators and the future reference for marketers to create more value and purchase intention.

Resource use policy based on standard (neoclassical) economic theory is driven by the assumption that “getting the prices right” is the key to sustainable resource use. Although most neo‐classical economists now agree that market prices may substantially undervalue biological features, the prevailing view is that “correct” market prices can be established through enlightened intervention in private markets. Using the examples of the Atlantic bluefin tuna, the American bison, and the passenger pigeon, we show that neither very high nor very low prices can ensure the survival of a particular species. With these cases as background, we compare and contrast three policy approaches to sustainability: weak sustainability, strong sustainability and Georgescu‐Roegen’s concept of a viable technology.

The purpose of this paper is to investigate the implications of supply chain strategies that manufacturing companies can use to minimise or overcome natural resource scarcity, and ultimately improve resource efficiency and achieve competitive advantage. The relationship between resource efficiency and competitive advantage is also explored.

The proposed research model draws on resource dependence theory. Data were collected from 183 logistics, purchasing, sustainability and supply chain managers from various manufacturing companies and analysed by applying the partial least squares structural equation modelling technique.

The results indicate that both buffering and bridging strategies improve resource efficiency; however, only bridging strategies seem to lead to firm’s competitive advantage in terms of ownership and accessibility to resources. The relationship between resource efficiency and competitive advantage is not supported.

Future research could confirm the robustness of these findings by using a larger sample size and taking into account other supply chain members.

This research provides guidance to managers faced with the growing risk of resource scarcity to achieve a resource efficient supply chain and an advantage over competitors.

Studies have explored the appropriate strategies for minimising dependencies caused by the scarcity of natural resources in the field of supply chain management; however, there is limited empirical work on investigating the impact of these strategies on resource efficiency and competitive advantage.

The Dutch market for meat substitutes has grown steadily, however, their market share is still low, and meat consumption in the Netherlands is not decreasing. For a transition towards a more plant-based diet, understanding consumer motives regarding meat substitutes is important. The purpose of this study was to explore what motives lay behind the appropriateness of the use of meat substitutes in different usage situations.

In total, 20 semi-structured in-depth interviews were performed to discover Dutch consumers’ associations with the terms “eating vegetarian” and “meat substitutes”, as well as motives regarding the situational appropriateness of meat substitutes.

The most mentioned motives for eating vegetarian were “environmental impact”, “health” and “animal welfare”, while meat substitutes were mainly eaten to replace meat in the meal. Most participants perceived vegetarian stir-fry pieces appropriate for almost all situations; the appropriateness of other meat substitutes was more situation-specific. The thematic content analysis yielded seven categories for the motives given for the (in)appropriateness of the four meat substitutes in six usage situations: “Functionality”, “Convenience”, “Properties”, “Preferences”, “Association with meat”, “Association with meals” and “Nutrition”. Mainly motives in the categories convenience and functionality (function of the meat substitute in a meal) were mentioned for all situations and other motives were situation-specific.

The focus in the development of plant-based foods is mostly on the product properties. The situational appropriateness and the underlying motives regarding meat substitutes have not yet been studied. This exploratory study suggests that these should be taken into consideration in the design of new meat substitutes.

Demonstrates changes in conservatism in a cross‐cultural and over time perspective. Using a micro‐model, attempts to explain the interdependency of materialism, religion, authority and family in establishing convention. Presents the findings of a questionnaire of undergraduates in North Carolina looking at the identities that reflect the suggested changes. Combines the analysis of a time series established over 20 years in the US with a cross sectional analysis of Germany to test a model of conservatism.

There are the interesting words of Myrdal in respect of the universality and commonness of what a scientific problem means:From then on more definitely I came to see that in reality there are no economic, sociological, psychological problems, but just problems and they are all mixed and composite. In research the only permissible demarcation is between relevant and irrelevant conditions. The problems are regularly also political and have moreover to be seen in historical perspective.

Water resources play a significant role in economic growth and socio-economic development. Jordan experiences water scarcity. As the water resources can be used in manufacturing and agriculture, their sustainable use and solutions to water scarcity problem can contribute to the sustainable economic and socio-economic development in Jordan. Furthermore, there are political and economic aspects of Jordan’s water scarcity. Jordan is trying to solve its water scarcity problem through projects. Based on an in-depth literature review, this chapter aims to investigate Jordan’s water scarcity problem, highlighting its political and economic aspects and their impacts on socio-economic development, and to propose solutions to the water scarcity problem in Jordan. Water is vital for economic development and political stability in Jordan. It is important for Jordan to use its water resources in an efficient, effective and sustainable way so that socio-economic development of Jordan can be supported. Unsustainable use of water resources can cause depletion of Jordan’s scarce water resources, which can exacerbate magnitude of water resource problem and hinder socio-economic development. This chapter can be beneficial to economists, politicians and academics.

The purpose of this paper is to characterise opportunity cost associated with the development of spectrum.

Differential Ricardian rent theory is used in the paper to explain the relationship between the development of spectrum along internal and external margins. Opportunity cost is introduced to characterise the link between spectrum and spectrum substitutes.

The study finds that workable strategies for spectrum reform require that economic externalities be internalised. Opportunity cost considerations can serve to improve spectrum management policy by justifying policy constraints and distribute the spectrum to the user with the best relative use.

Ricardian rent theory assumes that the “best” spectrum would be utilised first. In addition, there is no objective value‐based unit of spectrum and this limits the efficacy of Ricardo's theory.

The paper provides a more coherent explanation spectrum development and the spectrum management reform process.

The study provides a model for policy makers to introduce incremental change in the advent of novel wireless technologies

This is the first comprehensive study that has appeared on consumption and rationing in the present war. All types of rationing and the experience of a very large number of countries are brought under review, on the basis of material collected by the Economic Intelligence Service of the League of Nations. Rationing and other measures of consumption control are enforced in order to ensure an equitable distribution of limited—and in many countries drastically curtailed—supplies of certain essential goods, such as foodstuffs, clothing and fuel. But they play a further very vital role in war economy, by reducing (or limiting) civilian demand in order to liberate maximum resources for war purposes and by making possible the control of prices. The volume opens with a discussion of this broad problem of consumption control in war economy, the various methods of rationing, the conditions under which they can operate successfully and the connection between rationing and price control. Particular attention is naturally devoted to food. In the second chapter tables are given showing, for some thirty countries, by categories of consumers and groups of foodstuffs, rations prevailing in the spring of 1942. As regards Europe, available evidence seems to show that diets are adequate in the United Kingdom, Denmark, Sweden and Switzerland, and not critically short in calories (though apparently deficient in animal proteins, fats, minerals and certain vitamins) in Germany, despite the substantial cut in the German rations which occurred in April, 1942. The situation in Italy and Spain is decidedly worse than in Germany. This is also true of the occupied countries, except Denmark. Not only are the legal rations lower, but those rations are frequently unobtainable in the shops; and even if obtainable, it is often doubtful whether full rations can be purchased by the poorest classes, prices having risen out of all proportion to the frozen wage‐rates. Diets in the Netherlands, Czechoslovakia and Norway are nutritionally poorer and more deficient in calories than in Germany. In France and Belgium, where the rations represent about 60 per cent. of the pre‐war calorie consumption, many of those who are unable to eke out their rations by purchases on the “ black market ” are living at the barest level of subsistence. In Finland the rations represent about 55 per cent., in Poland (General‐Government) less than 50 per cent. of the pre‐war calorie consumption. In the latter country, in parts of Yugoslavia, and above all in Greece, there is famine. To meet differences in individual needs, two distinct systems have been evolved. In Germany, where about 90 per cent. of food consumption is rationed, rations are differentiated according to kinds of foods and classes of consumers—the latter being divided into categories by occupations (heavy worker, very heavy worker, light worker) and by sex, age, etc. The rations of bread, fat and meat of “ very heavy workers,” for example, are between two and three times as large as those of normal consumers. The German system, which has been generally applied in the occupied countries, is rigid and leaves a minimum of free consumers' choice. The British system is far more flexible. Bread and potatoes are free, thus permitting everyone to obtain an unlimited number of calories, while restaurant and canteen meals are supplementary to the individual's basic ration. Special needs are met by the allocation of extra rations to canteens catering to industrial workers, by the extension of free school meals, and by “ distribution schemes ” giving children, mothers and sick people first claim on available supplies of protective foods such as milk and fruit‐juice. Flexibility is also maintained by the group rationing of canned goods. According to this system each item within the group is valued in points and the consumer may buy whatever he desires up to a given total point value. It is considered of great importance that all, irrespective of income, should be able to obtain their quota of essential foods. Among the measures introduced for this purpose are the far‐reaching subsidies to keep down prices. Many aspects of the British system are naturally to be found elsewhere: for example, the subsidisation of staple foods is practised in Sweden and certain other European countries; Germany distributes free vitamin preparations to school children; canteen and school feeding is common in Germany and many of the occupied areas, though for these meals ration cards have, as a rule, to be given up. In the case of food, there are definite limits to the amount by which consumption can be reduced without endangering health and life; in the case of most, though not all, consumers' goods, there are no such obvious limits and, in fact, the consumption of such goods has been drastically curtailed. Available information on the subject is given in the third chapter. The group rationing system just mentioned has been universally applied in the case of clothing. But in Germany, most of the occupied areas and Italy, rationing lias been supplemented by a system of special permits, without which no purchase of certain articles of clothing can be made. By the first half of 1941, purchases of clothing in Germany had been reduced by some 50 per cent. from the pre‐war level. The clothes rationing introduced in the United Kingdom in June, 1941, led to a decrease of about 30 per cent. in the volume of sales in the second half of that year compared with the same period of 1940. Fuel, electric current, soap, and other articles of household consumption are subject to restrictions of varying degrees of severity; the production of luxury goods has been restricted or stopped, while such limited quantities as may reach the market are subject to drastically increased taxation; the production of most durable consumers' goods— refrigerators, household furniture, pianos, etc.—has likewise been stopped. The last chapter contains a brief analysis of the effects which war‐time restrictions have had on the aggregate volume of consumption in various countries. Consumption has been heavily reduced in all European countries and in Japan; in the United States, Canada, Australia and certain other countries it appears to have increased up to the latter part of 1941. In the United Kingdom the reduction in consumption provided about one‐third of the total domestic resources absorbed in the war effort in 1941. The requirements of war production have also been met to a considerable extent by the consumption of capital. Germany, in particular, has had to resort to capital consumption on a large scale, in spite of a curtailment of private consumption by some 25 to 30 per cent. In reviewing the whole body of evidence, especially concerning food rationing, it is observed that the rationing systems which have been developed are “ more than a mere method of restricting individual consumption. They aim in fact at securing a minimum diet for the population as a whole and, in spite of the necessary limitations imposed by the war‐time scarcity, they contain the elements of a distributive system in which consumption is guided not so much by individual purchasing power as by human wants.”
