In this paper, we aim at empirically uncovering the existence of price leadership in the passenger transport market, whose oligopolistic structure facilitates the strategic interaction among companies, with price being one of the principal elements of competition. The strategic interaction is particularly favoured by the fact that prices are easily observable online by all competitors. The analysis focuses on selected Italian city-pair markets that differ from one another with respect to the degree of inter- and intra-modal competition and to the characteristics of the transport services provided. We exploit this heterogeneity to study transport operators’ strategic interactions in different competitive environments. We find evidence of the existence of price leadership, even though results differ across city-pair markets. In particular, it emerges that the incumbent operator, in either the air or the rail sector, always holds the role of leader. 相似文献

This article looks at the relative importance of competing stories, particularly trade liberalization and skill-biased technical change, to explain changes in the skill premium and the real wages of unskilled and skilled workers in Mexican manufacturing using plant-level data. The channel through which technical change is observed is changes in the domestic price of machinery and equipment due to the availability of new and cheaper machines. The analysis also looks at trade-induced skill-biased technical change by taking into account changes in the price of machinery and equipment caused by changes in the tariff rate specific to machinery and equipment. Instrumental variables, including the price of machinery and equipment in the United States, are used to determine causality between the above effects and wages. Thus, the article provides evidence for some recent findings in the literature that link trade liberalization, skill-biased technical change occurring through technology embodied in machines and increases in the skill premium. 相似文献

In this paper, we consider a generalisation of the Hobson–Rogers model proposed by Foschi and Pascucci (Decis Eocon Finance 31(1):1–20, 2008) for financial markets where the evolution of the prices of the assets depends not only on the current value but also on past values. Using differentiability of stochastic processes with respect to the initial condition, we analyse the robustness of such a model with respect to the so-called offset function, which generally depends on the entire past of the risky asset and is thus not fully observable. In doing this, we extend previous results of Blaka Hallulli and Vargiolu (2007) to contingent claims, which are globally Lipschitz with respect to the price of the underlying asset, and we improve the dependence of the necessary observation window on the maturity of the contingent claim, which now becomes of linear type, while in Blaka Hallulli and Vargiolu (2007), it was quadratic. Finally, in this framework, we give a characterisation of the stationarity assumption used in Blaka Hallulli and Vargiolu (2007), and prove that this model is stationary if and only if it is reduced to the original Hobson–Rogers model. We conclude by calibrating the model to the prices of two indexes using two different volatility shapes. 相似文献

This paper quantifies the impact of international transport time on bilateral trade flows in goods using previously unexploited information drawn from a large data set on international parcel delivery times. In line with previous work, we find that an extra day spent in international transit reduces bilateral trade by just under 1% at the sample median. In addition, and for the first time in the literature, we examine the impact of time-related uncertainty, which requires traders to hold costly inventories or build costly redundancies into supply chains. We find that a one day increase in international transport time uncertainty reduces bilateral trade flows by just over 1%. Splitting the sample into developing and developed countries shows that international transit time matters primarily for south–south trade, whereas uncertainty is relatively more important for north–north trade. Using new data on trade in intermediate versus final goods, we also find some evidence that time and uncertainty both matter more for movements of intermediates of the type that takes place within global value chains. 相似文献

This paper investigates the links between product quality and the pro‐trade effect of ethnic networks using a large panel on bilateral stocks of immigrants with information for 19 OECD destination countries and 177 origin countries. In line with the approach of Rauch and Trindade, we classify traded goods according to their quality level and separately estimate pro‐trade elasticity of ethnic networks for each subgroup. We allow for heterogeneity of immigrants according to both the level of per capita income of their country of origin and their education level. Our findings suggest that the trend of the pro‐trade effect of immigrants over quality seems to be driven by the North–South specialisation across varieties for both supply and demand. Indeed, ethnic networks mostly facilitate imports of those varieties for which their countries of origin have a comparative advantage; as for exports, ethnic networks are more effective in promoting exports to their homeland of those varieties for which there is relatively higher demand. We show that the same trend applies to products characterised by the same degree of differentiation according to the classification proposed by Rauch and – given their lower liquidity constraints and advantages in human capital – we find a greater impact of high‐skilled migrants consistent across all quality levels. 相似文献

This paper proposes a decomposition of the change in inequality from the perspective of income groups. For every dichotomisation of the income distribution into poorer and richer parts, the decomposition allows to detect the change in the relative income gap between the two parts and the reranking between poorer and richer individuals. This decomposition approach is particularly suitable when analysts split the population between the individuals initially below the poverty line and those above the poverty line, since the decomposition allows to capture the effects of reranking and disproportional growth in income between poor and non-poor individuals and to compare these effects with those detected for the entire population. An application to Italian income data illustrates the proposed decomposition. 相似文献

This study explores the most effective retailing strategies with which luxury retailers can achieve a competitive advantage. The central role of services in enhancing the consumption experience in the luxury segment has been analyzed considering the pleasure boating sector, with a focus on the role that the dealer may have, both in the integration of different services and in the development of a durable competitive advantage. A qualitative study has been carried out through semistructured, in‐depth, one‐to‐one interviews with representatives of companies that deal with the pleasure boating sector. The results show that in the luxury pleasure boating sector, the introduction of a better‐defined retail strategy focused on services and its integration within the entire distribution channel may be crucial but also difficult to achieve in contexts that lack a marketing orientation. The contribution to extant literature on service in the pleasure boating sector and in luxury retailing in general is outlined. The managerial implications for practitioners in the pleasure boating sector are also discussed. 相似文献

Abstract We provide the first firm‐level evidence of the impact of the trade in producer services (‘offshoring’) on the labour market. Using a new data set from the UK that measures trade in services at the firm level, we find no evidence that importing intermediate services is associated with job losses or greater worker turnover. Using regression to control for observable differences between firms that import service inputs and those that do not, we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not. This seems likely to be the result of positive demand shocks, which cause a simultaneous increase in employment, output, and use of imported service inputs. 相似文献

Other-regarding preferences or decision errors are the main explanations put forward to justify contributions exceeding the
non-cooperative optimum in VCM games. An alternative rationale relies on ambiguity aversion. Ambiguity aversion increases
the perceived marginal benefit of own contributions, which in equilibrium will exceed the Nash level. We present a series
of experiments testing this hypothesis. To control for other-regarding preferences, we run a two-player game in which a human
player plays with a virtual agent. Players are assigned either to a risky setting (known probabilities of opponent’s choices)
or to an ambiguity setting (probabilities of opponent’s contribution are vague). Results show that ambiguity affects contributions.
However, attitude to ambiguity appears to be affected by the location of the aggregate Nash optimum inside the decision space. 相似文献
