A Dethroned King? The Limits of State Infrastructural Power in France

Since the 1980s in Western Europe, centralized states' control over subnational territories has been deeply affected by processes of Europeanization and regionalization. These changes have raised the issue of state territorial restructuring in a particular fashion: what capacity have formerly centralized states retained to steer and control subnational territories? The article draws on Mann's concept of infrastructural power, which refers to the state's capacity to exercise control and implement political decisions over the national territory. The article applies the two main operationalizations of the concept, namely the capability of the state to exercise control and the weight of the state in the subnational territories. Empirically, the article focuses on the French state in two policy sectors (education and housing). Although France is a most likely case, this article challenges this expectation, and shows the limits of the French state's infrastructural power over the subnational territories since the late 1980s.

Optimal Design of Permit Markets with an Ex Ante Pollution Target, August 2006

In this paper, we examine the design of permit trading programs when the objective is to minimize the cost of achieving an ex ante pollution target, that is, one that is defined in expectation rather than an ex post deterministic value. We consider two potential sources of uncertainty, the presence of either of which can make our model appropriate: incomplete information on abatement costs and uncertain delivery coefficients. In such a setting, we find three distinct features that depart from the well-established results on permit trading: (1) the regulator’s information on firms’ abatement costs can matter; (2) the optimal permit cap is not necessarily equal to the ex ante pollution target; and (3) the optimal trading ratio is not necessarily equal to the delivery coefficient even when it is known with certainty. Intuitively, since the regulator is only required to meet a pollution target on average, she can set the trading ratio and total permit cap such that there will be more pollution when abatement costs are high and less pollution when abatement costs are low. Information on firms’ abatement costs is important in order for the regulator to induce the optimal alignment between pollution level and abatement costs.

O impacto das energias renováveis na economia dos países emergentes: o caso de Cabo Verde

A elevada dependência dos combustíveis fósseis é uma das principais dificuldades sentidas no actual sistema energético de Cabo Verde. O preço dos combustíveis constitui um peso significativo, representando cerca de 70%, da estrutura de custos do preço de energia eléctrica. Com este trabalho, pretende-se analisar o impacto das energias renováveis no sistema energético e na economia de Cabo Verde, destacando a sua contribuição para a formação do PIB, no Preço, na Balança de Pagamentos, no Emprego, e no Serviço da Dívida, e estabelecer uma comparação com as ilhas da Macaronésia, em particular a Região Autónoma dos Açores. Contribuindo assim, para a discussão que poderá demonstrar que o potencial de renováveis por explorar, trará benefícios económicos para o país, pois a expectativa é superar os 50% de taxa de penetração de Energias Renováveis na produção de electricidade em Cabo Verde até 2020. Prevê-se que o consumo de electricidade que em 2010 era de 335 MWh, duplique até o ano de 2020, atingindo os 670 GWh. Segundo estudos efectuados, o país possui um potencial estimado de 2.600 MW de Energias Renováveis, tendo sido analisados mais de 650 MW em projectos concretos com custos de produção possivelmente inferiores aos dos combustíveis fósseis. Cabo Verde goza de boas condições para o aproveitamento de Energias Renováveis, mas a contribuição desse potencial, sobretudo eólica e solar, continuam muito limitado, pelo que o país deverá apostar no incremento da utilização dessas formas de energia para reduzir a dependência externa em matéria de energia. The high dependence on fossil fuels is one of the main difficulties in the current energy system in Cape Verde. The price of fuel is a significant, accounting for about 70%, and the cost structure of the price of electricity. With this work, seeks to analyze the impact of renewable energy in the energy system and the economy of Cape Verde, highlighting their contribution to the formation of BIP, in the Balance of Payments, in Employment, and the Service of Debt, and to draw a comparison with the islands of Macaronésia, in particular the Autonomous Region of Azores. Thus contributing to the discussion that may show that the potential of renewable energy by exploring will bring economic benefits to the country, because the expectation is to exceed the 50% penetration rate of Renewable Energy in the production of electricity in Cape Verde until 2020. It is estimated that the consumption of electricity in 2010 was 335 MWh, will double by the year 2020, reaching the 670 GWh. According to studies carried out, the country has an estimated potential of 2,600 MW of Renewable Energy, having been analyzed more than 650 MW in concrete projects with production costs possibly less than the fossil fuels. Cape Verde enjoys good conditions for the use of renewable energy, but the contribution of this potential, especially wind and solar, are still very limited, so that the country should invest in increasing the use of these forms of energy to reduce the dependence on foreign sources of energy.

Understanding unsuccessful attempts to quit smoking: a social phenomenology approach

Abstract OBJECTIVE The aim of this paper is to understand the experience of smokers in view of unsuccessful attempts to quit smoking. METHOD This study is based on social phenomenology. Between November and December of 2014, nine interviews were conducted with people that had attempted to quit smoking. The content of these interviews was analyzed and discussed based on the related literature. RESULTS Unsuccessful attempts to quit smoking are related to tobacco addiction; cigarettes are seen as a support to cope with everyday stressful situations. Attempts to quit the smoking habits were based on the need of health improvement and insistence of family and friends. Smokers reported the use of habit cessation strategies learned in support groups, but they also express expectation of specialized psychological support. CONCLUSION The study points out the need to expand the strategies of approaching smokers, and reinforcing psychological support in order to achieve success in the attempt to quit smoking.

Hot vs. cold: Sequential responses and preference stability in experimental games

In experiments with two-person sequential games we analyzewhether responses to favorable and unfavorable actions dependon the elicitation procedure. In our hot treatment thesecond player responds to the first player s observed actionwhile in our cold treatment we follow the strategy method and have the second player decide on a contingent action foreach and every possible first player move, without firstobserving this move. Our analysis centers on the degree towhich subjects deviate from the maximization of their pecuniaryrewards, as a response to others actions. Our results show nodifference in behavior between the two treatments. We also findevidence of the stability of subjects preferences with respectto their behavior over time and to the consistency of theirchoices as first and second mover.

The genetical theory of social behaviour.

We survey the population genetic basis of social evolution, using a logically consistent set of arguments to cover a wide range of biological scenarios. We start by reconsidering Hamilton's (Hamilton 1964 J. Theoret. Biol. 7, 1-16 (doi:10.1016/0022-5193(64)90038-4)) results for selection on a social trait under the assumptions of additive gene action, weak selection and constant environment and demography. This yields a prediction for the direction of allele frequency change in terms of phenotypic costs and benefits and genealogical concepts of relatedness, which holds for any frequency of the trait in the population, and provides the foundation for further developments and extensions. We then allow for any type of gene interaction within and between individuals, strong selection and fluctuating environments and demography, which may depend on the evolving trait itself. We reach three conclusions pertaining to selection on social behaviours under broad conditions. (i) Selection can be understood by focusing on a one-generation change in mean allele frequency, a computation which underpins the utility of reproductive value weights; (ii) in large populations under the assumptions of additive gene action and weak selection, this change is of constant sign for any allele frequency and is predicted by a phenotypic selection gradient; (iii) under the assumptions of trait substitution sequences, such phenotypic selection gradients suffice to characterize long-term multi-dimensional stochastic evolution, with almost no knowledge about the genetic details underlying the coevolving traits. Having such simple results about the effect of selection regardless of population structure and type of social interactions can help to delineate the common features of distinct biological processes. Finally, we clarify some persistent divergences within social evolution theory, with respect to exactness, synergies, maximization, dynamic sufficiency and the role of genetic arguments.

Additive utility with intransitive indifference and without independence: A homogeneous case

In the homogeneous case of one type of goods or objects, we prove theexistence of an additive utility function without assuming transitivityof indifference and independence. The representation reveals a positivefactor smaller than 1 that infuences rational choice beyond the utilityfunction and explains departures from these standard axioms of utilitytheory (factor equals to 1).

The political cost of reforms

This paper formalizes in a fully-rational model the popular idea that politiciansperceive an electoral cost in adopting costly reforms with future benefits and reconciles it with the evidence that reformist governments are not punished by voters.To do so, it proposes a model of elections where political ability is ex-ante unknownand investment in reforms is unobservable. On the one hand, elections improve accountability and allow to keep well-performing incumbents. On the other, politiciansmake too little reforms in an attempt to signal high ability and increase their reappointment probability. Although in a rational expectation equilibrium voters cannotbe fooled and hence reelection does not depend on reforms, the strategy of underinvesting in reforms is nonetheless sustained by out-of-equilibrium beliefs. Contrary tothe conventional wisdom, uncertainty makes reforms more politically viable and may,under some conditions, increase social welfare. The model is then used to study howpolitical rewards can be set so as to maximize social welfare and the desirability of imposing a one-term limit to governments. The predictions of this theory are consistentwith a number of empirical regularities on the determinants of reforms and reelection.They are also consistent with a new stylized fact documented in this paper: economicuncertainty is associated to more reforms in a panel of 20 OECD countries.

Offshoring and directed technical change

To study the short-run and long-run implications on wage inequality, we introducedirected technical change into a Ricardian model of offshoring. A unique final good isproduced by combining a skilled and an unskilled product, each produced from a continuumof intermediates (tasks). Some of these tasks can be transferred from a skill-abundant Westto a skill-scarce East. Profit maximization determines both the extent of offshoring andtechnological progress. Offshoring induces skill-biased technical change because it increasesthe relative price of skill-intensive products and induces technical change favoring unskilledworkers because it expands the market size for technologies complementing unskilled labor.In the empirically more relevant case, starting from low levels, an increase in offshoringopportunities triggers a transition with falling real wages for unskilled workers in the West,skill-biased technical change and rising skill premia worldwide. However, when the extentof offshoring becomes sufficiently large, further increases in offshoring induce technicalchange now biased in favor of unskilled labor because offshoring closes the gap betweenunskilled wages in the West and the East, thus limiting the power of the price effectfueling skill-biased technical change. The unequalizing impact of offshoring is thus greatestat the beginning. Transitional dynamics reveal that offshoring and technical change aresubstitutes in the short run but complements in the long run. Finally, though offshoringimproves the welfare of workers in the East, it may benefit or harm unskilled workers inthe West depending on elasticities and the equilibrium growth rate.

The Effect of Teacher Expectations on Student Achievement: Does The Pygmalion Effect Hold True for Cape Verde?

The present study is about the relationship between teacher expectations and student achievement. Do teachers have the power to influence student achievement? This is the question at hand. Are students under the influence of their teachers in regards to how they perceive themselves as achievers and ultimately how well they perform? What are the other factors that come into play when assessing student’s academic achievement? In light of the literature written on this topic, the two most prevalent theories are (1) Pygmalion in the Class and (2) The Sustaining Effect. These theories show a direct and determinant relationship between teacher expectations and student achievement. The main objective of this study was to investigate if in Cape Verde, teachers follow the same trend. Responses to teacher and student surveys carried out at Domingos Ramos High School gave revealing insights into how Capeverdean teachers view their students and the role the teachers themselves play in supporting the studen’s academic performance. Is the teacher’s expectation of their students the last word? In general, teachers do have a powerful influence on their students for good or for bad, but the key questions are: (1) are they aware of this power and (2) how well do they manage it? This paper includes an in-depth discussion on the different factors that influence student achievement and research carried out at an urban secondary school which characterizes how teachers and students view their roles in the student’s academic success. Recommendations are also provided to assist teachers in managing their expectations to maximize their role as a positive contributor to the success of their students.

Este trabalho aborda o sector do Turismo de Cruzeiros Marítimos na ilha de São Vicente, visando aferir em que medida a oferta turística da ilha encontra-se equilibrada com a procura dos navios de cruzeiros. O turismo em Cabo Verde é considerado como o sector central de desenvolvimento da economia do país e o mercado do turismo de cruzeiros marítimos apresenta uma excelente alternativa para a maximização dos impactos socioeconómicos na ilha de São Vicente. Quanto à metodologia, a pesquisa foi caracterizada como exploratória e descritiva, com uma abordagem tanto qualitativa como quantitativa. O uso da técnica da observação directa, como recurso metodológico na colecta dos dados, levou a concluir que a estrutura portuária da cidade é bastante atractiva no que tange à questão de segurança, da paisagem e dos recursos naturais oferecidos na ilha. Também a utilização do programa SPSS no tratamento dos inquéritos recolhidos possibilitou a realização de várias análises o que permitiu chegar a conclusões importantes da investigação. A pesquisa foi desenvolvida com base a pesquisa bibliográfica, consulta em sites de Internet e acesso a documentos que possuem informações sobre a evolução do turismo de cruzeiros em São Vicente. This work intends to study the sector of Cruise Tourism in São Vicente Island, in Cape Verde. Its main objective is to gauge to what extent the touristic offer is balanced with the demand for this specific niche of tourism. Tourism in Cape Verde is being considered as a central sector for economic growth, and this type of tourism surely presents itself as an excellent alternative for the maximization of social and economic impacts, in the island. In terms of methodology used, this research is seen as both exploratory and descriptive; hence, it has a qualitative and a quantitative approach. Direct observation as a methodological resource has allowed us to conclude that the island’s port infrastructure is very attractive in terms of safety, landscape, and natural resources the island has to offer its visitors. The use of SPSS for data treatment, in terms of our survey, allowed the realization of many analyses that lead to very important conclusions to this research. The research also relied on bibliographic review, web surfing for information, and analyses of documentation related to the evolution of cruise tourism in São Vicente.

Additional utility of insiders with imperfect dynamical information

In this paper we consider an insider with privileged information thatis affected by an independent noise vanishing as the revelation timeapproaches. At this time, information is available to every trader. Ourfinancial markets are based on Wiener space. In probabilistic terms weobtain an infinite dimensional extension of Jacod s theorem to covercases of progressive enlargement of filtrations. The application ofthis result gives the semimartingale decomposition of the originalWiener process under the progressively enlarged filtration. As anapplication we prove that if the rate at which the additional noise inthe insider s information vanishes is slow enough then there is noarbitrage and the additional utility of the insider is finite.

Biased representation of homothetic preferences on homogeneous sets

In the homogeneous case of one-dimensional objects, we show that any preference relation that is positive and homothetic can be represented by a quantitative utility function and unique bias. This bias may favor or disfavor the preference for an object. In the first case, preferences are complete but not transitive and an object may be preferred even when its utility is lower. In the second case, preferences are asymmetric and transitive but not negatively transitive and it may not be sufficient for an object to have a greater utility for be preferred. In this manner, the bias reflects the extent to which preferences depart from the maximization of a utility function.

Recursive contracts

We obtain a recursive formulation for a general class of contractingproblems involving incentive constraints. Under these constraints,the corresponding maximization (sup) problems fails to have arecursive solution. Our approach consists of studying the Lagrangian.We show that, under standard assumptions, the solution to theLagrangian is characterized by a recursive saddle point (infsup)functional equation, analogous to Bellman's equation. Our approachapplies to a large class of contractual problems. As examples, westudy the optimal policy in a model with intertemporal participationconstraints (which arise in models of default) and intertemporalcompetitive constraints (which arise in Ramsey equilibria).

Robust response transformations based on optimal prediction

Nonlinear regression problems can often be reduced to linearity by transforming the response variable (e.g., using the Box-Cox family of transformations). The classic estimates of the parameter defining the transformation as well as of the regression coefficients are based on the maximum likelihood criterion, assuming homoscedastic normal errors for the transformed response. These estimates are nonrobust in the presence of outliers and can be inconsistent when the errors are nonnormal or heteroscedastic. This article proposes new robust estimates that are consistent and asymptotically normal for any unimodal and homoscedastic error distribution. For this purpose, a robust version of conditional expectation is introduced for which the prediction mean squared error is replaced with an M scale. This concept is then used to develop a nonparametric criterion to estimate the transformation parameter as well as the regression coefficients. A finite sample estimate of this criterion based on a robust version of smearing is also proposed. Monte Carlo experiments show that the new estimates compare favorably with respect to the available competitors.
