Abstract
We introduce a new class of bankruptcy problems in which the value of the estate is endogenous and depends on agents’ investment decisions. There are two investment alternatives: investing in a company (risky asset) and depositing money into a savings account (risk-free asset). Bankruptcy is possible only for the risky asset. We define a game between agents each of which aims to maximize his expected payoff by choosing an investment alternative and a company management which aims to maximize profits by choosing a bankruptcy rule. Our agents are differentiated by their incomes. We consider three most prominent bankruptcy rules in our base model: the proportional rule, the constrained equal awards rule and the constrained equal losses rule. We show that only the proportional rule is a part of any pure strategy subgame perfect Nash equilibrium. This result is robust to changes in income distribution in the economy and can be extended to a larger set of bankruptcy rules and multiple types. However, extension to multiple company framework with competition leads to equilibria where the noncooperative support for the proportional rule disappears.

Notes
The constrained equal awards rule represents a family of rules favoring smaller claimants, the constrained equal losses favoring larger claimants and the proportional rule lies in between the two. The constrained equal awards (losses) rule is regressive (progressive) and the proportional rule is both regressive and progressive.
Another difference is that in our model agents deposit either zero or all of their endowment whereas in Kıbrıs and Kıbrıs (2013) intermediate decisions are also allowed. However, this is not a major reason for differences in results since if we allow agents to optimally choose their deposit amounts, we would have corner solutions due to our risk-neutrality assumption.
In fact, what we mean by \(w_{l}\) (\(w_{h}\)) is the part of the income that is reserved for investment by a type \(l\) (\(h\)) agent.
Also note that each agent has one information set in each subgame and two actions. Therefore, the terms strategy and action refer to same objects in subgames \(\Gamma ^{P}\), \(\Gamma ^{CEA}\), and \(\Gamma ^{CEL}\).
Note that \(F={ CEL}\) for \(\theta =0\), \(F={ CEA}\) for \(\theta =1\), and \(F=T\) for \( \theta =1/2.\) Moreover, for all \(\theta \in [0,1]\), \(F^{\theta }\) coincides with \({ CEA}\) (on adjusted \(\theta \)-claims) if \(E\le \mathop {\textstyle \sum }\nolimits _{i\in N}\theta c_{i}\) and \({ CEL}\) (on adjusted \((1-\theta )\) -claims) if \(E\ge \mathop {\textstyle \sum }\nolimits _{i\in N}\theta c_{i}\). Finally, note that \( P\) is not a member of the TAL-family.
For this assumption, we further need to assume that there are even number of agents of each type.
I would like to thank an anonymous reviewer for raising this question.
