Following a Supreme Court decision in 1954, natural gas markets in the U.S. were subject to 35 years of intensive federal regulation. Several studies have measured the deadweight loss from the price ceilings that were imposed during this period. This paper concentrates on an additional component...

The objective of the paper is to elaborate a simulation model to analyse inter and intra-modal competition in the transport industry, based on game theory models. In our setting, consumers choose a transport mode and an operator to travel on a given city-pair; operators strategically decide on...

The run-up in oil prices since 2004 coincided with growing investment in commodity markets and increased price comovement among different commodities. We assess whether speculation in the oil market played a role in driving this salient empirical pattern. We identify oil shocks from a large...

Traditional least squares estimates of the responsiveness of gasoline consumption to changes in gasoline prices are biased toward zero, given the endogeneity of gasoline prices. A seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes, but this...

When today’s actions can affect tomorrow's value of an asset and when the principal does not have access to hard information, either about productive activity or monitoring activity, two incentive problems must be simultaneously solved: first, the ‘ex-ante’ moral hazard problem of inducing...

Stricter laws require more incisive and costlier enforcement. Since enforcement activity depends both on available tax revenue and the honesty of officials, the optimal legal standard of a benevolent government is increasing in per-capita income and decreasing in officials' corruption. In...

We analyze the design of optimal regulation of a domestic monopolist that also competes in an unregulated foreign market. We show how foreign activities by the regulated firm affect domestic regulation, consumers’ surplus and firm’s profits. Although expansion in unregulated foreign markets...

We analyze the impact of mandatory access on the infrastructure investments of two competing communications networks, and show that for low (high) access charges firms wait (preempt each other). Contrary to previous results, under preemption a higher access charge can delay first investment....

This Paper develops an argument explaining why retail prices may rise in response to the deregulation of opening hours. We make this point in a model of imperfect duopolistic competition. In a deregulated market retailers view the choice of opening hours as a means to increase the degree of...
