The aim of this paper is to describe in detail a set of newly developed indicators of the quality of competition policy, Competition Policy Indexes, or CPIs. The CPIs measure the deterrence properties of a competition policy in a jurisdiction, where for competition policy we mean the antitrust...

Based on my recent work with several co-authors this paper explores the relationship between discretion, reputation, competition and entry in procurement markets. I focus especially on public procurement, which is highly regulated for accountability and trade reasons. In Europe regulation...

Harassment bribes - payments people give in order not to be denied what they are legally entitled to - are common in for example India. Kaushik Basu recently made a radical proposal to reduce its occurrence: Legalize the act of giving the bribe and double the fine for accepting the bribe! We...

We study interactions with different durations and termination rules in a (quasi) continuous-time prisoner’s dilemma experiment. We find that cooperation is easier to achieve and sustain with deterministic horizons than with stochastic ones; end-game effects emerge, but subjects postpone them...

Harassment bribes - payments people give in order not to be denied what they are legally entitled to – are common in for example India. Kaushik Basu recently made a '’radical'’ proposal to reduce its occurrence: Legalize the act of giving the bribe and double the fine for accepting the...

Contracts often reward inefficient tasks and are not enforced ex post. We provide an explanation based on the relationship between explicit contracts and implicit agreements. We show that signing but then ignoring contractual clauses requiring costly, inefficient, verifiable tasks (A) may...

When subjects interact in continuous time, their ability to cooperate may dramatically increase. In an experiment, we study the impact of different time horizons on cooperation in (quasi) continuous time prisoner's dilemmas. We find that cooperation levels are similar or higher when the horizon...

We study networks of relations - groups of agents linked by several cooperative relationships - exploring equilibrium conditions under different network configurations and information structures. Relationships are the links through which soft information can flow, and the value of a network lies...

In this paper we explore theoretically the relationship between explicit and implicit/relational contracting distinguishing between the ex-ante decision to sign an explicit contract and the ex-post decision wheter to actually apply it. We show, among other things, that the relational efficient...

This paper provides a comprehensive discussion of the deterrence properties of a competition policy regime. On the basis of the economic theory of law enforcement we identify several factors that are likely to affect its degree of deterrence: 1) sanctions and damages; 2) financial and human...
