This paper studies the causes and consequences of in-season changes of the headcoach of association football teams. We exploit data from the highest level of<br/>Dutch professional football during 14 successive seasons. An in-season change of<br/>the head-coach depends on recent match results and the...

Background: General Practitioners have limited means to compete. As quality is hard to observe by patients, GPs have incentives to signal quality by using instruments patients perceive as quality.<br/>Objectives: We investigate whether GPs exhibit different prescribing behavior (volume and value of...

Cannabis is the most popular illegal drug. Its legal status is typically justified on<br/>the grounds that cannabis use has harmful consequences. Empirically investigating<br/>this issue has been a fertile topic for research in recent times. We provide an<br/>overview of this literature, focusing on studies...

In this paper we document evidence of systemic risk taking from syndicated loan<br/>pricing. Using U.S. syndicated loan data, we find that the borrower's idiosyncratic risk is positively priced whereas systematic risk is negatively related to loan spreads, controlling for firm, loan and bank specific...

The Shapley value for directed graph (digraph) games, TU games with limited cooperation introduced by an arbitrary digraph prescribing the dominance relation among the players, is introduced. It is defined as the average of marginal contribution vectors corresponding to all permutations that do...

Three metrics are designed to assess Colombian financial institutions’ size,<br/>connectedness and non-­substitutability as the main drivers of systemic<br/>importance: (i) centrality as net borrower in the money market network;<br/>(ii) centrality as payments originator in the large-value payment...

Contracts between health insurers and providers are private; i.e. not public. By<br/>modelling this explicitly, we find the following. Insurers with bigger provider networks,pay higher fee-for-service rates to providers. This makes it more likely that a patient is treated and hence health care costs...

In this paper we propose a methodology for constructing decision rules for in-<br/>teger and continuous decision variables in multiperiod robust linear optimization<br/>problems. This type of problems finds application in, for example, inventory management, lot sizing, and manpower management. We show...

This paper introduces a tractable model of health insurance with both moral hazard<br/>and adverse selection. We show that government sponsored universal basic insurance should cover treatments with the biggest adverse selection problems. Treatments not covered by basic insurance can be covered on...

The three-step generalized methods of moments (GMM) approach of Kapoor, Kelejian and Prucha (2007), which corrects for spatially correlated errors in static panel data models, is extended by introducing fixed effects, a spatial lag, and a one-period lag of the dependent variable as additional...
