The application of Engel’s Curve in a single-product perspective may dramatically change the role of quality in affecting the dynamics of economic performance. This paper introduces a specification of preferences that regards quality as luxury, and quantity as necessary. The analysis is carried out by using a framework similar to Grossman’s and Helpman ’s (1991), while quality is defined as in Stokey (1988). The resulting consumer’s demand crucially depends on quality. Quality is potentially able to prevent the process, implied by neoclassical models, that leads the value of consumption goods to decline over time. By doing so, quality also affects the consumption bundle shares and the variety-specific consumption growth rates, thus influencing all dynamic quantitative variables of the economy.

Pareto in hisManuale asserts that the price concept is inessential for the notion of equilibrium. This view deeply contrasts with the Arrow-Debreu’s dominant approach of Walrasian derivation. This identifies general equilibrium with a system of prices at which the decentralized choices of economic agents match. In this paper the author justifies and gives substance to the Paretian point of view. The differential merit of the Paretian approach is its independence of assumptions of price taking and of convexity in preferences and in production possibility sets. These assumptions are necessary, in the walrasian framework, only to maintain the centrality of prices, but they clash against the request of realism. (JEL:BOO, D51, D60)

Poverty is one of the hoariest socio-economic problems in the world and a complex concept that attracted the involvement of several researchers and policymakers. Nowadays, it is the number one global agenda as it has indicated on SDG. Ethiopia is one of the poorest countries in the world and the level of poverty is more challenging in rural areas compared to urban. Currently, there are great tendencies over the world to measure poverty using Alkire and Fosters' MPI approach among different approaches of poverty assessment. This study aimed at assessing multidimensional rural poverty status household's poverty in Burji and Konso area in Southern Ethiopia. To address this objective, 368 households were selected using simple random sampling techniques. The data were collected from both primary and secondary sources. Interview schedule, focused group discussion, key informant interview, and observation methods were implemented to collect primary data. Alkire and Foster Methodology with modified four dimensions and 14 indicators used to analyze multidimensional rural poverty. The study reveals as the highest three deprivations 97.8% of cooking fuel, 92.6% of the floor, and 76.1% of drinking water. The multidimensional Poverty Index (MPI) of the study area was 0.419 with 76.6% of incidence and 54.7% the intensity of multidimensional rural poverty. The highest (15%) contributor to MPI was deprivation in school attendant and the highest (36%) deprivation dimension was in living Standard out of four dimensions.

This paper analyzes an economy in which all agents are pursuing the common good (or social welfare) but choices are decentralized, i.e., each agent can choose his/her action in the set of the actions that he/she can perform. One wonders if it is enough the common goal of maximizing social welfare to their will be achieved. The paper examines both the cases in which the choice made by each agent does not directly influence those of other agents, as in the competitive equilibrium analysis, and the case in which there is a direct influence, as in the game theory analyses. In the first case, we get that the common goal of maximizing social welfare is not enough to reach it, but it is necessary to coordinate the actions of individual agents by extending information to redistribute initial endowments and by introducing an appropriate social organization. We get the maximum social welfare without further intervention for the cases describable with the theory of games, but only for games of complete information. If the information is incomplete, some further coordination is generally required.

There is considerable quarrel as to what extent the shape and malfunctioning of contemporary African states can be attributed to the colonial experience or whether the precolonial heritage must be taken into account. Generally, the correct answer is that both, precolonial forms of political organization and the imposition of the colonial state, characterize the African situation. Yet, it is possible to distinguish more specifically between the two formative influences and to gauge their particular importance. Empirically, the result of the colonial encounter was, on the one hand, a subversion of traditional concepts of legitimacy and, on the other hand, still is the fact that the development of market economies and liberal democracies remains unlikely. Theoretically, I propose to use the notion of reciprocity to describe and analyze three historical forms of power relations, namely, clientelism, colonialism and cleptocracy. By reconstructing the historicity and malleability of the concept, I try to show its usefulness and adequacy to outline basic features of societal organization.

Previous research finds that agency workers are less satisfied with their job than regular workers. This paper analyzes whether this difference can be explained by the duration of the working contract agency workers are employed on. The analysis leads to three results. First, agency workers’ contract type does not explain their lower job satisfaction. Second, agency workers on permanent contracts are significantly less satisfied with their job than regular workers on the same contract. Third, agency workers on fixed-term contracts do not differ in job satisfaction from regular workers on both fixed-term and permanent contracts. The difference in job satisfaction between permanently employed agency and regular workers can partly be explained by changes in the reference point. Overall, the results, however, lend support to the conclusion that agency workers on fixed-term contracts regard their employment as stepping stone while those on permanent contracts appear to be trapped in this type of employment.

This paper assesses Thaler and Sunstein’s claim that policies that nudge individuals towards healthy lifestyles promote the welfare of those individuals, as judged by themselves. I argue that Thaler and Sunstein switch between two different interpretations of that clause. One interpretation gives the clause a wide range of applicability, but drains it of its content as a repudiation of paternalism. The other interpretation makes it more meaningful to say that people want to make the choices they are being nudged towards, but applies to a much narrower range of cases than Thaler and Sunstein have in mind.

We examine the association between various components of consumption expenditure and happiness in the Health and Retirement Study (HRS), a nationally representative sample of older Americans. We find that only one component of consumption is positively related to happiness—leisure consumption. In contrast, consumption of durables, charity, personal care, food, health care, vehicles, and housing are not significantly associated with happiness. Second, we find that leisure consumption is associated with higher levels of happiness partially through its effect on social connectedness, as indexed by measures of loneliness and embeddedness in social networks. On one hand, these results counter the conventional wisdom that “material goods can’t buy happiness.” One the other hand, they underscore the importance of social goods and social connectedness in the production of happiness.
