The performance of service industries in Canada has been lower than that of good industries over the last four decades, with noticeable exceptions such as for railways and telecommunication carriers. Service industries were less economically (and technically) efficient in that they generated less output value (quantity) per hour worked (level and growth) or per combined unit of labour and capital (multifactor productivity growth) than good industries. The relative output price of services declined slightly over time compared with goods. At the disaggregated level, changing relative output prices were substantial and proved to be an important factor explaining the relative satisfactory economic performance of many service industries despite their low technical performance. Nevertheless, the output share of service industries increased over that period, sustained, mainly, by the growing recourse of all firms to outsourcing of services.  相似文献

This article analyzes the struggle between traditional travel agencies and airlines to gain control of the Spanish airline services market. Also analyzed is the strong emergence of a third player, online travel portals that act as online travel agencies. We use a multinomial logit model to study the influence of 27 socio-economic factors and trip attributes on passenger purchase channel choice. The results show that the profile of a passenger who has a greater likelihood of making his/her bookings online is that of a young person, a student or educated to a high level, a habitual traveler, booking a simple journey and using an LCC. The factors linked to an increased likelihood of making purchases by phone include: being male, middle-aged, on a business or short trip, and the passengers usually use a travel agency. Finally, passengers who are over 65 years of age, with a lower academic level, who use a travel agency and are going to make a more complicated journey, are more likely to purchase their tickets in-store.  相似文献

Using BoC-GEM-Fin, a large-scale dynamic stochastic general equilibrium (DSGE) model with real, nominal, and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle. Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target.  相似文献

This article provides a framework for designing and evaluating corporate risk management and hedging programs. Corporate risk management has the potential to create substantial shareholder wealth by protecting companies from unexpected events that could force them to put their strategic investment plans on hold or even endanger their existence. However, assessing the performance of risk management, and how it is expected to increase the value of the enterprise, is a difficult undertaking because the costs of risk management tend to be much easier to quantify—indeed, they often appear directly on the firm's bottom line—than the benefits. The author begins by discussing how to evaluate the benefits and costs of a risk management program in general terms, and then focuses more directly on the assessment of corporate hedging programs, which are generally conducted with derivatives. In practice, there are many obstacles to designing and carrying out a successful hedging program. But one of the most common has been the tendency of top managements to insist that hedging programs be “costless.” The author argues that just as the purchase of fire insurance is not viewed as waste of funds or a bad investment if the insured house does not burn down, the use of derivatives in a well‐designed hedge should not be viewed as a mistake if the derivative position produces losses. To guard against this mistake, the people who design and implement risk management strategies must ensure that their CEOs and boards understand the possible outcomes of the strategy—including losses on derivatives position—and how the strategy itself increases the (expected) value of the firm. Further, management should attempt to communicate the principles underlying its risk management program and the value created by its hedging strategy to the investment community.  相似文献

We find necessary and sufficient conditions for the market symmetry property, introduced by Fajardo and Mordecki (Quant Finance 6(3):219–227, 2006), to hold in the Ornstein–Uhlenbeck stochastic volatility model, henceforth OU–SV. In particular, we address the non-Gaussian OU–SV model proposed by Barndorff-Nielsen and Shephard (J R Stat Soc B 63(Part 2):167–241, 2001). Also, we prove the Bates’ rule for these models.  相似文献

This paper provides an approach to the measurement of the “scale effects” in the allocative profit efficiency. To be specific, we evaluate the improvements of profit that can be accomplished by means of a change in the scale size, once technical efficiency is achieved. New decompositions of the allocative efficiency into a scale effect component and the corresponding residual mix effect component are derived.  相似文献
