Abstract: Business groups in emerging markets perform better than unaffiliated firms. We study how business groups can substitute some functions of missing institutions, for example, enforcing contracts. In a two period model, there is no contract enforcement in the first period. The firms...

In transition and developing countries, we observe rather high levels of corruption even if they have democratic political systems. This is surprising from a political economy perspective, as the majority of people generally suffers from high corruption levels. Our model is based on the fact...

This paper studies majority voting on taxes when tax evasion is possible. We characterize the voting equilibrium where the agent with median taxed income is pivotal. Since the ranking of true incomes does not necessarily correspond to the ranking of taxed incomes, the decisive voter can differ...

We discuss survey evidence on individuals' willingness to sanction norm violations - such as evading taxes, drunk driving, fare dodging, or skiving o work - by expressing disapproval or social exclusion. Our data suggest that people condition their sanctioning behavior on their belief about the...

Why do banks remain passive? In a model of bank-firm relationship we study the trade-off a bank faces when having defaulting firms declared bankrupt. First, the bank receives a payoff if a firm is liquidated. Second, it provides information about a firm’s type to its competitors. Thereby,...

Banks entering an emerging market face a lot of uncertainty about the risks involved in lending. We use a unique unbalanced panel of nearly 700 short-term loans made to SMEs in Slovakia between January 2000 and June 2005. Of the loans granted, on average 6.0 per cent of the firms defaulted....

It has been argued that competing banks make inefficiently frequent use of collateralization in situations where they are better able to evaluate a project's risk than entrepreneurs. We study the bank's choice between screening and collateralization in a model where banks do not have this...

The number of firm bankruptcies is surprisingly low in economies with poor institutions. We study a model of bank-firm relationship and show that the bank's decision to liquidate bad firms has two opposing effects. First, the bank gets a payoff if a firm is liquidated. Second, it loses the rent...

This paper develops a model of social norms and cooperation in large societies. Within this framework we use an indirect evolutionary approach to study the endogenous formation of preferences and the coevolution of norm compliance. Thereby we link the multiplicity of equilibria, which emerges in...

This paper incorporates tax morale into the Allingham Sandmo (1972) model of income tax evasion. Tax morale is interpreted as a social norm for tax compliance. The norm strength, depending on the share of evaders in the society, is endogenously derived. Taxpayers act conditionally cooperative,...
