In many countries, the authorities turn a blind eye to minimum wage laws that they have themselves passed. But if they are not going to enforce a minimum wage, why have one? Or if a high minimum wage is not going to be enforced one hundred percent, why not have a lower one in the first place?...

We analyse households’ responses to an unanticipated change in consumption opportunities and evaluate their implications for the nature and formation of preferences. We study the tariff experiment conducted by South Central Bell where local telephone measured tariffs were introduced for the...

Dynamic inconsistency provides a theoretical basis for discussions of policy credibility: when the government cannot commit its future policies, the incentive to deviate from the 'optimal' plan renders it incredible. We derive the best policy in the absence of precommitment as the feedback Nash...

This paper compares adversarial with cooperative industrial and trade policies in a dynamic oligopoly game in which a home and foreign firm compete in R&D and output and, because of spillovers, each firm benefits from the other’s R&D. When the government can commit to an export subsidy, such a...

We examine optimal industrial and trade policies in a series of dynamic oligopoly games in which a home and a foreign firm compete in R&D and output. Alternative assumptions about the timing of moves and the ability of agents to commit intertemporally are considered. We show that the home export...

We characterize optimal trade and industrial policy in dynamic oligopolistic markets. If governments can commit to future policies, optimal first-period intervention should diverge from the profit-shifting benchmark to an extent which exactly offsets the strategic behaviour implied by Fudenberg...

What happens when a previously uncovered labour market is regulated? We exploit the introduction of a minimum wage in South Africa and variation in the intensity of this law to identify increases in wages for domestic workers and find no statistically significant effects on the intensive or...

Using several unique data sets on wage agreements at both the firm- and the industry-levels in France, we examine the impact of typical European wage-setting institutions on the form and the degree of wage rigidity. We highlight different stylized facts concerning wage stickiness. First, in...

This paper analyzes the contribution of the minimum wage to the well documented rise in earnings inequality in Mexico between the late 1980s and the early 2000s. We find that a substantial part of the growth in inequality, and essentially all the growth in inequality in the bottom end, is due to...

The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised. When demand is linear, a small restriction on price only increases consumer surplus if the elasticity of demand exceeds the elasticity of supply; with log-linear or...
