Airline competition in the British Isles

We study the relationship between pricing and market structure on the routes connecting the UK and the Republic of Ireland. Because in 2007 the European Commission prohibited the takeover of Aer Lingus by Ryanair, the analysis focuses on their pricing strategies in particular. We use an original dataset of fares posted on-line, which allows to control for the fares’ inter-temporal pattern for each specific flight and each carrier’s specific yield management system. Our evidence supports the European Commission’s view that the elimination of a competitor in the Irish airline market is likely to have harmful consequences for consumers.     

ON THE SOURCES OF THE INFLATION BIAS AND OUTPUT VARIABILITY

Why do dynamic inconsistencies in monetary policy exist? In this paper, a traditional model with output inefficiencies is introduced, but monetary policy is allowed to be influenced by the various constituencies in the economy that pressure Congress in turn to pressure the Central Bank to adopt a particular policy stance. This paper shows that in this economy an inflation bias arises because of the lobbying pressures of outsiders. Furthermore, it shows that if lobbying pressures are high enough, an inflation bias cannot be avoided for any finite level of Central Bank independence. It also shows that introducing the realistic feature of lobbying pressures has an impact on the stabilization properties of monetary policy. When a supply shock occurs, the shock is totally absorbed by a non‐myopic trade union, which has no lobbying costs. This is independent of any finite degree of conservativeness of the central banker, who has to accept an extreme increase in price instability. It is shown that monetary policy delegation is therefore sub‐optimal in achieving price stability compared with labor‐market reforms meant to remove monopsonistic elements. However, the same structural policies will induce greater output instability by strengthening the power of conservative central bankers.     

R&D INVESTMENT, CREDIT RATIONING AND SAMPLE SELECTION

We study whether R&D‐intensive firms are liquidity constrained, by modelling their antecedent decision to apply for credit. This sample selection issue is relevant when studying a borrower–lender relationship, as the same factors can influence the decisions of both parties. We find firms with no or low R&D intensity to be less likely to request extra funds. When they do, we observe a higher probability of being denied credit. Such a relationship is not supported by evidence from the R&D‐intensive firms. Thus, our findings lend support to the notion of credit constraints being severe only for a sub‐sample of innovative firms. Furthermore, the results suggest that the way in which the R&D activity is organized may differentially affect a firm's probability of being credit constrained.     

A case study of pricing strategies in European airline markets: The London – Amsterdam route

Published fares London–Amsterdam are used to examine the pricing practices of low-cost and legacy carriers when operating in a large and crowded market. We investigate two strategies of market segmentation involving the time before departure the ticket has been bought, inter-temporal segmentation, and the duration of the stay, implicit segmentation. We find inter-temporal price discrimination emerges as an important strategy for all pricing but the two legacy carriers involved, British Airways and KLM, differ in their use of stay restrictions; British Airways does not assign a specific role to the duration of stay, while KLM make use of such rules extensively in price setting.     

Technological spillovers and productivity in Italian manufacturing firms

We study whether a firm’s total factor productivity dynamics is positively influenced by its own R&D activity and by the technological spillovers generated at the intra- and inter-sectorial level. Our approach corrects simultaneously for the endogeneity and the selectivity biases introduced by the use of a firm’s own R&D as a regressor. The evidence suggests that a firm’s involvement in R&D activities accounts for significant productivity gains. Firms also benefit from spillovers originating from their own industries, as well as from innovative upstream sectors.     

Airline Market Power and Intertemporal Price Dispersion

This paper analyzes the empirical relationship between market structure and price dispersion in the airline markets connecting the U.K. and the Republic of Ireland. Price dispersion is measured by the Gini coefficient, calculated using fares posted on the Internet at specific days before takeoff. We control for passengers' heterogeneity in their purpose of travel, as well as for such peak periods as Christmas and Easter. Our finding of a negative correlation between competition and price dispersion suggests that competition is likely to hinder the airlines' ability to price discriminate, although this effect appears to be lessened in peak periods.     

Assessing the returns to collaborative research: Firm-level evidence from Italy

We use firm-level data from Italian manufacturing firms to assess the relationship between various types of R&D and total factor productivity growth, including collaborative research with other firms and universities. A novel twist to our empirical analysis is that we estimate a sample selection model, which allows us to treat the decision to conduct R&D as endogenous. We find strong evidence of positive returns to collaborative research with other companies, whereas collaborative research with universities does not appear to enhance productivity. This result implies that firms may conduct R&D with universities when appropriability conditions are weak and the outcomes of such research projects do not yield direct strategic benefits.     

A Dynamic Model of Advertising and Product Differentiation

This paper analyses a differential game of duopolisticrivalry through time where firms can use advertisingand price as competitive tools. Two cases are consideredwhereby: (1) advertising has the main effect ofincreasing market size and firms differ in productionefficiency; (2) advertising has both predatory and cooperativeeffects in a symmetric market. The former shows thatmarket shares and advertising shares are positivelycorrelated and that market size increases with thedifference in firms' relative efficiency. The latterhighlights the differences in the feedback andopen-loop strategies. It is shown that firms' advertisingare strategic complements and that profits are higherin the feedback equilibrium because firms advertise more.The applicability of the model in markets wherefranchise contracts and dealership agreements operateis also discussed.     

Booking and flying with low‐cost airlines

The first part of the paper develops a theoretical framework for the analysis of strategic behaviour of European low‐cost airlines that emphasises the role of product differentiation. The second part uses original survey data to assess the effectiveness of low‐cost airlines' distribution strategies. Finally, an econometric model is developed to assess the joint impact of the factors affecting the level of the fares charged by low‐cost airlines. The evidence suggests that, among other things, the highest prices normally are paid for tickets bought between 30 and 8 days before departure, and thus indicates an original pricing strategy that differentiates low‐cost airlines from traditional carriers.
