Globalization, long-haul flights and inter-city connections (2017) -Joint with X. Fageda-  (Submitted) 

Abstract: In this paper, we examine the impact of non-stop flights on the connectivity of European cities with distant locations from the rest of the world. We use data on inter-city passenger flows including non-stop and connecting traffic so that we have a precise measure of the economic and social links between cities. We apply a matching procedure and run regressions using instrumental variables to deal with the potential endogeneity bias of the variables for non-stop flights. We find a strong causal relationship between the amount of total traffic and the supply of non-stop long-haul flights in the considered inter-city markets. Traffic increases from the shift from ‘not having’ to ‘having’ non-stop flights can be more than double. Such increase in the amount of traffic does not seem to be related with a systematic change in fares.

Residential water demand: evidence from monetary and non-monetary policies (In progress)

Abstract: This article intends to assess the effectiveness of monetary and non-monetary policies in managing residential water demand. To do this, I exploit micro data from Castelldefels during the period 2004-2014, a municipality with a high proportion of houses with garden and swimming pools, whose users passed both a drought period and the introduction of two extra blocks in an increasing blocks tariff system. By applying a regression discontinuity (RD) design approach, preliminary results show that a 68% in average price increase reduces consumption in about 10.35% implying an elasticity of 0.15. Also, that non-monetary policies affect a wider population.

Competition on the gasoline retail market. The heterogeneous effect of entry of branded stations, supermarkets and unbranded stations -joint with J. Perdiguero- (In progress)

Abstract: In this paper, we use a unique dataset to disentangle which is the effect of the branded stations, supermarkets and unbranded stations on retail equilibrium prices. By exploring the effect of an increase in the market share of all three agents in the same geographical space, we are able to shed light not only on the price strategy of each competitor, but also in the degree of competition among each other. Using data on the Metropolitan Area of Barcelona, preliminary results show that all three agents entry to the market by setting a lower price than the incumbents. Also, that the supermarket chains set the lowest price, followed by the unbranded stations. Moreover, our results also show that despite the supermarkets set a lower price that the unbranded entrants, the effect over competitors of the last is greater than the effect generated by the formers. Finally, the results show that the increase of branded stations do not impact prices.
