Abstract Generic drugs are sold at a fraction of the original brand price. Yet, generic entry typically produces a drop in the quantity market share of the molecule losing exclusivity. This effect is economically and statistically significant for a large dataset covering hundreds of prescription drugs sold in the US during the period 1994Q1-2003Q4. This paper proposes the first systematic analysis of what appears to be a market anomaly. We propose a model to characterize the market equilibrium b...

There is general consensus that water meters are necessary for promoting an efficient use of water through some form of pricing mechanism based on effective consumption. However, available evidence on benefits and costs of metering is scant and often based on a small sample of households. This paper uses data of the first large-scale universal metering programme in England to produce a comprehensive analysis of the impact of metering on consumption, social efficiency and distributional outcomes....

This paper investigates the effects of behavioural interventions on energy conservation in naturally ventilated offices. Our aim is to inform building managers, environmental consultants, and social scientists on the effectiveness of low-cost, easy-to-implement interventions aimed at reducing energy waste and carbon emissions in a setting where individuals do not have direct financial gain and have low awareness of the environmental impact of their actions. The interventions consist of three typ...

We study adoption by more than 150,000 households of an optional transitional water tariff implemented in the South-East of England in conjunction with an universal metering programme. We document how inertia leads customers to relinquish substantial financial gains, with less than a third of customers who would benefit from adopting the transitional tariff actually doing so. We also show how households responds not only to overall gains, but also to more short-term gains from adopting the tarif...

ABSTRACTNaturally ventilated offices enable users to control their environment through the opening of windows. Whilst this level of control is welcomed by users, it creates risk in terms of energy performance, especially during the heating season. In older office buildings, facilities managers usually obtain energy information at the building level. They are often unaware or unable to respond to non-ideal facade interaction by users often as a result of poor environmental control provision. In t...

Advances in communication technology have led to a remarkable increase in the tradability of services, resulting in a substantial increase in offshoring of services over the last two decades. Research investigating how this surge in service offshoring affects employment, has been largely hampered by the paucity of suitable microdata. This paper tries to fill this gap by using a newly constructed database of Belgian firms that combines individual transaction-level data on international trade in g...

This paper shows that a pro-competitive shock leading to a steep price drop in one market segment may benefit substitute products. Consumers move away from the cheaper product and demand for the substitutes increases, possibly leading to a drop in consumer surplus. The channel leading to this outcome is non-price competition: the competitive shock on thefirst set of products decreases the firms' ability to invest in promotion, which cripples their ability to lure consumers. To assess the empiric...

type="main"> Is there any evidence that innovation and technological progress are constrained by competition and fostered by monopoly power? Our results, based on a constructed dataset of U.S. manufacturing industries observed over more than two decades, suggest that this is not the case. On the contrary, using both patent statistics and productivity growth as alternative measures of innovation and technological change, we observe faster technological advances in more competitive markets. These ...
