We identify a natural way of ordering functions, which we call the interval dominance order and develop a theory of monotone comparative statistics based on this order.  This way of ordering functions is weaker than the standard one based on the single crossing property (Milgrom and Shannon,...

These are additional notes relating to the paper `The Comparative Statics of Constrained Optimization Problems`, which is appearing in Econometrica. It gathers together material present in various earlier versions of the paper, as well as some new material, which are not found in the published...

We consider an observer who makes a finite number of observations of an industry producing a homogeneous good, where each observation consists of the market price and firm specific production quantities.  We develop a revealed preference test (in the form of a linear program) for the hypothesis...

The paper presents a model where individuals decide to become workers or entrepreneurs in the presence of capital constraints and where individuals differ in wealth levels.  The model shows that the higher the initial level of inequality in wealth is, the lower the long run aggregate wealth of...

Using a simple one-shot bribery game, we find evidence of a negative externality effect and a framing effect.  When the losses suffered by third parties due to a bribe being offered and accepted are high and the game is presented as a petty corruption scenario instead of in abstract terms...

This paper examines the relationship between norm enforcement and in-group favouritism behaviour.  Using a new two-stage allocation experiment with punishments, we investigate whether in-group favouritism is considered as a social norm in itself or as a violation of a different norm, such as...

Monitoring corruption typically relies on top-down interventions aimed at increasing the probability of external controls and the severity of punishment.  An alternative approach to fighting corruption is to induce bottom-up pressure for reform.  Recent studies have shown that both top-down...

We study in-group favouritism and out-group discrimination in a multiplayer dictator game.  An allocator divides a large sum of money among three groups of 20 recipients each and Self.  Allocations to groups are divided equally among the group members.  The three groups are supporters of the...
