Carbon taxes and the double dividend hypothesis in a recursive-dynamic CGE model for Spain

A carbon tax is potentially a policy that can reduce CO₂ emissions and mitigate climate risks, at lowest economy-wide costs. We develop a dynamic CGE model for Spain to assess the economic and environmental effects of a carbon tax, and test the double dividend (DD) hypothesis. We simulate the impact of three carbon taxes: €10, €20 and €30 per ton of CO₂. For each tax, four ‘revenue recycling’ scenarios are examined: a reduction of taxes on capital, on labor, on value-added tax, and a scenario in which revenues are not recycled. We find a DD for taxes of €10/ton and lower, within five to seven years of implementation. We estimate an annual CO₂ emissions reduction of around 10% with this tax. Under some circumstances, the DD can be achieved for a tax of €20/ton. In any case, recycling revenues to cut pre-existing taxes reduces costs of imposing carbon taxes.     

Value-in-context in crowdfunding ecosystems: how context frames value co-creation

The aim of this paper is to analyse the phenomenon of crowdfunding and determine whether it can be considered a service ecosystem, where the context frames innovation through value co-creation. A qualitative, multiple case study approach is used to analyse three platforms and six initiatives in the Spanish arts sector. The findings reveal that crowdfunding can be considered an ecosystem where value-in-context frames seven types of value co-creation, offering a contribution both to ecosystem theory and to the field of co-creation.     

Social Interaction and Beer Consumption

The aim of this article is to describe young consumers’ attitudes and conduct regarding beer consumption, analyzing the consumer as an individual (addressing internal factors) and in a collective (external factors). The research was designed in Brazil involving 52 participants, divided into 16 focus groups, and the respective data was transcribed and analyzed. The findings show three distinct types of consumers were identified. The authors termed these the Inductor, the Induced, and the Sophisticated. The article details how each type of consumer can be distinguished through different attitudes and factors. The results suggest that, rather than thinking of beer consumption as an individual item, beer consumption should be thought of as different types, involving different behavior, attitudes, and social interaction. The article demonstrates originality and value to put forward the notion that beer consumption should not be defined as an individual item. The framework offered in this article will assist future researchers to consider consumption of different types and brands of beer, based on social interaction.     

Productivity differences and the dynamic effects of labor movements

Barriers to labor mobility across countries coexist with substantial differences in living standards largely attributable to productivity differences. A growth model with endogenous labor movements is used to assess the effects on output, capital accumulation and welfare of removing barriers to labor mobility. The model is parameterized so that it is consistent with evidence on historical labor movements, and is applied to two cases: the enlargement of the European Union and the (hypothetical) creation of a common labor market in the North America. The main finding is that there are large resulting gains in terms of output and welfare.     

Survey measures of risk aversion and prudence

This paper utilizes a thought experiment conducted by the Bank of Italy to estimate absolute and relative risk aversion along with absolute and relative prudence for a broad cross-section of Italian households. Upper and lower bounds are calculated for each parameter, and comparisons are made across socio-demographic groups. Evidence is found of decreasing absolute risk aversion, decreasing absolute prudence, increasing relative risk aversion, and increasing relative prudence.     

Do the Retired Elderly in Europe Decumulate Their Wealth? The Importance of Bequest Motives,Precautionary Saving,Public Pensions,and Homeownership

We use microdata on a large number of European countries from the Survey of Health, Ageing and Retirement in Europe (SHARE) to examine the wealth accumulation (saving) behavior of the retired elderly in Europe. We find that less than half of the retired elderly in Europe are decumulating their wealth and that the average wealth accumulation rate of the retired elderly in Europe is positive though relatively moderate (6.6 percent over a 3-year period). These findings suggest that the Wealth Decumulation Puzzle (the tendency of the retired elderly to not decumulate their wealth or to decumulate their wealth more slowly than expected) applies in the case of Europe. Moreover, our regression results suggest that bequest motives, generous public pension systems, and the reluctance of retired elderly homeowners to sell or borrow against their owner-occupied housing are the primary explanations for the existence of the Wealth Decumulation Puzzle in Europe.
