Goals and guesses as reference points: a field experiment on student performance

2022

In this paper, we study overconfidence and goal-setting in academic performance, with and without monetary incentives. Students enrolled in a microeconomics course were offered the possibility of setting their own target grade before taking part in the final exam. They were also asked to guess their grade immediately after they had taken the exam (“post-diction”). In general, students overestimated their performance, both at the goal-setting and at the post-diction stages. Controlling for several sources of this bias (cognitive abilities, academic record and self-reported academic confidence), we find that the use of monetary rewards mitigates the overestimation of potential achievements an…

Canonical correlation in multivariate time series analysis

1997

We analyze a class o f state space identification algorithms for time series, based on canonical correlation analysis in the ligth of recent results on stochastic systems theory calle d « subspace methods » .These can be describe as covariance estimation followed b y stochastic realization .The methods offer the major advantage o f converting the nonlinear parameter estimation phase in traditional V A R M A models identification in to the solution o f Riccati equation but introduce at the same time some no n trivial mathematical problem s related to positivity. The states o f the forward -backward innovations representation have an interpretation : Instrumental Variables estimators .

Informational interactions and the future of cities

1998

Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. It seems that these activities need to be more spatially concentrated than traditional manufacturing activities. These new trends affect both the structure of cities and the structure of city systems. The specific nature of the new activities concentrated in city centers makes them information intensive. These activities consume human capital, knowledge and hightech capital, which are all rapidly changing inputs; they are based on complex decisionmakingprocesses; this renders them highly information-dependent. Inasmuch as these activities are the…

What is next for the Washington consensus? The fifteenth anniversary, 1989-2004.

2004

Winter2004/2005, Vol. 27 Issue 2, p, 7p; (AN 15818079); International audience; The article reports on the fifteenth anniversary of the Washington consensus with special focus on the past fifteen years accomplishments. Washington consensus was promulgated in 1989. In the past fifteen years, the United States saw some impressive growth with strong employment, low inflation, and high productivity gains, while emerging countries were hit by a string of financial crises. It states that the economic performance of developing countries in the past 15 years is disappointing at best, alarming at worst. It talks about the contributions of globalization in redefining the international currency stage.…

Production network and financing

1993

L'un des grands apports de Keynes à la science économique est d'avoir découvert que le financement courant de l'économie se fait à partir de la production courante. La théorie moderne des émissions, développée par B. Schmitt, nous permet de saisir maintenant que la rémunération des travailleurs n'est pas issue de fonds préalablement accumulés, et que l'émission des salaires est la source unique du financement de la production. Pourtant on considère souvent que la "finance" est un moyen complémentaire de financement que les banques mettent à la disposition des entreprises. Or, il apparaît que la logique même de l'émission de la monnaie interdit de retenir une telle hypothèse. La "finance" ne…

Gini index, inequality comparisons and maximim axiom : a paradox

1999

Inequality is appreciated only through a relevant measure, traditionally the Gini index, but this one presents a weakness that prevents to consider it as valid: to a same Gini may correspond many distributions. For the most simple case, a concentration curve with two linear segments, a criterion is proposed, based on the maximin: beside curves with same Gini, the more egalitarian is those in which each poor has the higher revenue. However, this does not allow to decide for two curves with different Gini: two indeterminate zones appear. This is extended to curves with three linear segments and two kinks.

A biproportional measure of multidimensional inequality

1999

Bradburd and Ross have proposed a measure of multidimensional inequality based on a quadratic-loss criterion: one matrix is compared to another even if they have not the same margins. This is reconsidered. One removes the effect of size variation between the analyzed distribution and the reference distribution by giving to the two matrices the same margins with a biproportional operator. The size differences inside the analyzed structure are removed by a bimarkovian biproportional operator. As homogeneity does not signify equality, the homogeneous reference structure is replaced by a uniform matrix to be compared to the first matrix.

Island Development Model Specialisation: A Panel Data Analysis Comparing Evolutionary Tourism Model, Industrial to Community-Based (2010–2019)

2022

Islands are frequently characterised by an economic structure centred on tourism and the service sector. This specialisation has taken different forms and characterisations concerning the chosen or spontaneously developed model. To understand the development choices and patterns, this article analyses sixteen islands and archipelagos in the European Union over ten years from 2010 to 2019. A panel data analysis was based on critical variables identifying the tourism industry model from those that could represent a proxy of the community-based tourism model. The principal component analysis was adopted to compare the evolutionary trends of these two different ways of choosing the island’s tou…
