A wide range of empirical biases hampers hedge fund databases. In this paper we focus upon survival-related biases and disentangle look-ahead biases due to self-selection of funds and due to fund termination. Self-selection arises because funds voluntarily report their information to data...

This paper examines how firms succeed to leverage supplier involvement in product development. The paper extends earlier work on managing supplier involvement by providing an integrated analysis of results, processes and conditions both at the level of individual development projects and the...

This paper investigates time allocation decisions in new ventures of female and male entrepreneurs using a model that distinguishes between effects of preferences and productivity on the number of working hours. Using data of 1,158 entrepreneurs we find that the preference for work time in new...

In this paper we discuss the level set method of Joó and how to use it to give an elementary proof of the well-known Sion’s minimax result. Although this proof technique is initiated by Joó and based on the inter-section of upper level sets and a clever use of the topological notion...

This paper hypothesizes that hot convertible debt windows represent periods with lower convertible debt-related financing costs. Supporting this premise, we find that the stock price impact of Western European convertible debt announcements is significantly less negative during hot convertible...

: In this paper we describe the use of a set covering model with additional constraints for scheduling train drivers and conductors for the Dutch railway operator NS Reizigers. The schedules were generated according to new rules originating from the project "Destination: Customer" ("Bestemming:...

This article develops an explanatory framework for understanding the growth and development of temporary agency work (TAW) and the related industry. The analysis shows that explanations based on economic logic are helpful in understanding the choice of TAW in general. These explanations,...

In recent years, the scope of internal auditing has broadened considerably, increasing the importance of internal auditing as part of the organization’s management control structure. This expanding role has changed the demands being put on internal auditors. Their new role requires...

We propose a two-stage MRQAP to analyze dynamic network data, within the framework of an equilibrium-correction (EC) model. Extensive simulation results indicate practical relevance of our method and its improvement over standard OLS. An empirical illustration additionally shows that the EC...
