We investigate properties of the volatility estimator, which is proportional to the square of oscillations of the bridge formed by the logarithm of the incremental price of a financial instrument at a specified time interval. In the framework of the geometric Brownian motion model for price...

We study job durations using a multivariate hazard model allowing for worker-specific and firm-specific unobserved determinants. The latter are captured by unobserved heterogeneity terms or random effects, one at the firm level and another at the worker level. This enables us to decompose the...

High student dropout rates are a continuing concern within higher education and have received considerable attention for decades. Despite numerous proposed interventions, it remains unclear which interventions are effective, and what the pivotal active ingredients are. This paper systematically...

This paper describes a new method for assigning letter grades to students based on their raw scores, which I call Multi-Curve Grading (MCG). The intuition behind the method is that a class can be composed of several different subgroups, each of which should be assigned a different grade. In...

From the point of view of economic development, education is the acquisition of knowledge and skills through experiences from conception onwards over the life cycle that increase productivity broadly defined. Education can occur through, but is not limited to, formal educational activities such...

Spurred by international commitments and expanded funding at the national and international level, attendance in education and associated years of schooling have expanded substantially in developing countries in recent years. But has this expansion in enrolments reduced existing inequalities in...

This paper examines norms about gender equality of the education of children and adults in Bangladesh using a recent household survey for two cohorts of married women. Education norms are found to differ substantially across cohorts, with women from the younger cohort being far more positive...

This study investigates the relationship between social trust and intelligence. The extreme bound analysis of Levine and Renelt is employed to directly assess the strength of the nexus. The findings confirm the positive and robust nexus between social trust and intelligence. We have contributed...
