Abstract:

In my dissertation, I address two topics in applied microeconomics. First two chapters deal with the functioning of school admission mechanisms and their affects on student school choice behavior. Third chapter deals with the question of optimal bankruptcy law design.

Pupil-school matching mechanisms play a critical role in the schooling system. They affect the behavior of students and—through the information they convey—also the behavior of the schools and the authorities responsible for education policy. In the first chapter (joint with Daniel Münich), using a computational simulation model, we analyze the functioning of an admission scheme used in the Czech Republic as a prototype of decentralized, ability-based admission schemes widely used in the world to assign pupils to upper-secondary schools. Our findings show large incidence of strategic misrepresentation of school preferences among applicants, large differences between revealed and trued demand, and large incidence of justified envy in the resulting matching. We point out several implication this could have for functioning of schooling systems.

In the second chapter, I empirically study the behavior of students under the Czech pupil-school matching mechanism. Using district-level data on demand for public gymnasia, I find significant evidence that students do not apply to their most preferred schools, opting rather for a less-preferred, but safer option. Furthermore, using data on individual student school choices, I also find that students with weak socio-economic background misrepresent their preferences more often than other students.

In the third chapter (joint with Ondřej Vychodil), we develop a model of a debt contracting problem under bankruptcy regimes differing by a degree of softness. In the model, the degree of softness is associated with the extent to which the absolute priority rule can be violated. We show that when the degree of softness can be set individually for each project, then the debtor's tendency to excessive risk-taking can be eliminated and the first best solution can be attained. When it is given exogenously by a bankruptcy law, then a completely tough law results in a lower distortion from the first best than a soft law with a moderate degree of softness.

Abstract:

The dissertation consists of three chapters on corporate bankruptcy:
In the first chapter (joint with Ondřej Knot), we develop a model of a debt-contracting problem under bankruptcy regimes differing by a degree of softness. In the model, the degree of softness is associated with the extent to which the absolute priority rule can be violated. We show that when the degree of softness can be set individually for each project, then the debtor's tendency to excessive risk-taking can be eliminated and the first best solution can be attained. When it is given exogenously by a bankruptcy law, then a completely tough law results in a lower distortion from the first best than a soft law with a moderate degree of softness.

The second chapter documents that the recent Czech bankruptcy practice tended to delay the ultimate exit of a firm when it can be expected to have a harsher ex-post effect on the firm's employees. Bankruptcy duration is regressed on unemployment rate, size and other controls, applying three alternative methods—OLS regression, parametric duration (survival) analysis, and quantile regression—on the cross-section population of 903 Czech corporate bankruptcies that were completed during 2004 by the distribution of returns among creditors. The chapter shows that bankruptcy procedures last longer in an environment with higher unemployment rate. Moreover the magnitude of the unemployment rate's effect on duration increases with the firm's size. These results are observed for the first four years of a bankruptcy procedure, after which they are no longer evident.

The third chapter introduces a simple unifying model that can be used to illustrate majority of the ex ante effects of corporate bankruptcy law discussed the economic literature. A dozen of elementary ex ante inefficiencies of too soft or too tough bankruptcy laws are presented, clustered in five types—debt contracting (credit rationing, creditor structure, other), project choice (effort choice, risk choice, entrenchment), debtor's bankruptcy decision (strategic default, staving off bankruptcy, gambling on resurrection), creditor's bankruptcy decision (inefficient liquidation) and provision of private information (debtor's incentive to share, creditor's incentive to monitor).
