This paper presents a new multivariate test for the detection of unit roots. Use is made of the possible correlations between the disturbances of different series, and constrained and unconstrained SURE estimators are employed. The corresponding asymptotic distributions are obtained and a table...

This paper studies the relationship between a microfinance institution (MFI) and its credit officers when the latter discriminate against a group of the target population. Using survey data from Uganda, we provide evidence that credit officers are more biased against disabled borrowers than...

This paper studies labor market discriminations as an agency problem. It sets up a principal-agent model of a firm, where the manager is a taste discriminator and has to make unobservable hiring decisions that determine the shareholder’s profits because workers differ in skills. The paper...

Exploiting an exceptional historical example, this paper proposes an original method to address the existence of sovereign creditor moral hazard. As the coronas which are observable only during a total eclipse of the sun, market-specific prices of repudiated bonds are observable only when...

Criticizing the Efficient Market Hypothesis (EMH) on the basis of highly volatile asset prices is conceptually wrong as efficiency is about rationality and information, not about stability. Speculative bubbles are compatible with rational valuation, and hence with market efficiency. As rational...

Pyramids, cross-ownership, rings, and other complex features inducing control tunnelling are frequent in the European and Asian industrial world. Based on the matrix methodology, this paper offers a model for measuring integrated ownership and threshold-based control, applicable to any group of...

This paper offers a new representation of discrimination on the job market based on the most recent findings in the socio-psychological academic literature about human behaviour. Put it simply, it is assumed that the agents prefer working with people like themselves. This "affinity" principle is...
