How can we measure and compare the relative performance of production units? If input and output variables are one dimensional, then the simplest way is to compute efficiency by calculating and comparing the ratio of output and input for each production unit. This idea is inappropriate though,...

We develop a sequential trade model of Iceberg order execution in a limit order book. The Iceberg-trader has the freedom to expose his trading intentions or (partially) shield the true order size against other market participants. Order exposure can cause drastic market reactions (“market...

We consider a large trader seeking to liquidate a portfolio using both a transparent trading venue and a dark pool. Our model captures the price impact of trading in transparent traditional venues as well as the execution uncertainty of trading in a dark pool. The unique optimal execution...

Generalized single-index models are natural extensions of linear models and circumvent the so-called curse of dimensionality. They are becoming increasingly popular in many scientific fields including biostatistics, medicine, economics and finan- cial econometrics. Estimating and testing the...

Within a standard three-tier regulatory model, a benevolent prin- cipal delegates to a regulatory agency two tasks: the supervision of the …rms (two-type) costs and the arrangement of a pricing mecha- nism. The agency may have an incentive to manipulate information to the principal to share the...

We consider a vertically related market characterized by down- stream imperfect competition and by the monopolistic provision of an essential facility-based input, whose price is set by a social-welfare maximizing regulator. Our model shows that the regulatory knowl- edge about the cost for...

This paper addresses the issue of how to design the institutional structure of an industry which provides two differentiated products. One good is supplied by a regulated monopoly and the other is produced in a competitive (unregulated) segment. Two possible institutional patterns are compared....

The Reversible Jump Markov Chain Monte Carlo (RJMCMC) method can enhance Bayesian DSGE estimation by sampling from a posterior distribution spanning potentially nonnested models with parameter spaces of different dimensionality. We use the method to jointly sample from an ARMA process of unknown...

Dieser Beitrag setzt sich mit der Leistungsfähigkeit von Strukturgleichungsmodellen bei der Validitätsprüfung von Messmodellen für hypothetische Konstrukte auseinander und geht auf ausgewählte Problembereiche bei der gängigen Anwendung dieser Methodik für die Skalenkonstruktion ein....
