Toward Conceptualizing Trip-Chaining Behavior: A Review

This paper critically reviews the existing literature on multiple-trip journeys, and clarifies the need for an improved conceptualization and modeling strategy. It also suggests different ways that trip chaining can be treated and a theory constructed. Exploratory studies, from the 1960s and 1970s, are briefly surveyed (Section I). While they developed the existence and complexity of travel patterns, they lacked any comprehensive theoretical framework. However, they were useful in that they supported the conceptual framework of various kinds of stochastic processes used by transportation scientists to replicate trip-chaining behavior (Section II). Scientists subsequently improved their conceptualization of the issue by grounding individual behavior on the principle of utility maximization. In this latter area the economists have emphasized theoretical concerns while transportation researchers have emphasized operationality (Section III).     

All that Glitters is not Gold. The Political Economy of Randomized Evaluations in Development

Randomized control trials (RCTs) have a narrow scope, restricted to basic intervention schemes. Experimental designs also display specific biases and political uses when implemented in the real world. Despite these limitations, the method has been advertised as the gold standard to evaluate development policies. This article adopts a political economy approach to explore this paradox. It argues that the success of RCTs is driven mainly by a new scientific business model based on a mix of simplicity and mathematical rigour, media and donor appeal, and academic and financial returns. This in turn meets current interests and preferences in the academic world and the donor community.     

Histoire de quelques miroirs déformants orient-occident

The paper brings to light a literary fabrication cast as a “chinoiserie» published in Paris in 1788 and tentatively explores its implicit message. The fabrication implies the title—allusion to the pamphlet written by the radical Morelly then commonly credited to Diderot—, the author—the Chinese philosopher contemporary of Socrates—, the alleged translation—which could never have occurred—, and the commentary attributed to a Jesuit of the French mission in China. The genuine author of the fabrication, a plea for the abolishion of the death penalty and a satire on the legal institution and the Clergy, is Louis Lavicomterie who later will be a member of the Montagne and will vote the death of Louis XVI. He fathered the book during the French Revolution. The reconstitution of the historical context helps to decipher the cryptic purpose of this chinese message. Behind Confucius, Lavicomterie has introduced Voltaire. The text reflects the moral and intellectual expectations at the eve of the turmoil: the increasing search for secularization and the rejection of the fundamental divine rights of the Ancien Régime.     

The Social Regulation of Markets: Why Microcredit Fails to Promote Jobs in Rural South India

There is growing evidence that microcredit does little to support self‐employment. Two main explanations are typically emphasized: from a microeconomic perspective, the poor have been argued to lack the skills, resources and motivation to start their own businesses; from a macroeconomic perspective, local markets are often saturated. This article uses first‐hand data from rural South India to explore a third explanation which focuses on the social regulation of markets. Drawing on a household survey, the authors show that self‐employment and microcredit are uncorrelated, and that women and lower castes have a significantly lower chance of starting up a business. The businesses they do start tend to be smaller, less profitable and based in very specific sectors. Qualitative insights into the workings of local economies show that caste and gender‐based social regulations influence local markets determining who can produce or sell what, to whom, and at what price. The authors observe that real markets are affected by power relations and structured through social institutions rather than being the sum of interactions between free and competitive individuals. These findings show the importance of integrating self‐employment programmes into broader policies for transforming the social regulation of markets and for eradicating discrimination against women and lower castes.     

EMERGENCE OF LEAPFROGGING FROM RESIDENTIAL CHOICE WITH ENDOGENOUS GREEN SPACE: ANALYTICAL RESULTS

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.     

Women and Money: Lessons from Senegal

This article examines the complexity and diversity of women's informal financial practices using data from surveys conducted in Senegal. It suggests that these practices are at the centre of a constant dialectic between short‐term and long‐term horizons, between the requirements of daily survival and the demands of community solidarity, and between personal aspirations and collective constraints. These practices also clearly illustrate a desire among the women in Senegal to impose a form of financial self‐discipline, and to create situations that will oblige them to earn income. The socio‐economic diversity among these entrepreneurs is also underscored. Informal financial arrangements are both a product and producer of gender inequalities and inequalities among women, as reflected in the research. This has direct policy implications, especially for microfinance products. If they are to be effective, microfinance services must develop beyond a standard, one‐size fits all model and become more innovative and adaptable to the diverse demands of women. They must be combined with complementary measures that challenge the systemic causes of inequality. Microfinance programmes should draw on informal financial arrangements while challenging their tendency to perpetuate inequality.     

Winding Down in a Quebec Mining Town: a Case Study of Schefferville

The pattern of decline in a mining region is examined using a case study of Schefferville. A critical examination is made of Lucas's model of youth to maturity in community development, and a further two stages are suggested - winding down and closure of a town. The discussion centres on the characteristics of community and corporate winding down in Schefferville: the restructuring of the local workforce, disinvestment, relocation of capital, and company withdrawal from housing, municipal affairs, and public services.
Les auteurs entreprennent une étude du processus de déclin dans les régions minikres en se servant de l'exemple de Schefferville. En partant d'une critique du modtle fait par Lucas sur les stages d'évolution et de maturation d'une communauté, les auteurs proposent d'y ajouter deux autres Ctages, soit celui de déclin et celui de la fermeture définitive d'une ville. La période de déclin est donc caractérisée par la restructuration de la main d'ceuvre, par la diminution des investissements, par la relocalisation de capitaux, et par le retrait de la sociktk minikre au niveau du logement, des affaires municipales, et des services publics dans la ville.
