Accounting for Environmental Influences in Stochastic Frontier Models: With Application to International Airlines 总被引:3,自引:3,他引:0
The principal aim of this paper is to measure the efficiency of international airlines. We obtain measures of technical efficiency from stochastic frontier production functions which have been adjusted to account for environmental influences such as network conditions, geographical factors, etc. We observe that two alternative approaches to this problem have been proposed in the efficiency measurement literature. One assumes that the environmental factors influence the shape of the technology while the other assumes that they directly influence the degree of technical inefficiency. In this paper we compare the results obtained when using these two approaches. The two sets of results provide similar rankings of airlines but suggest differing degrees of technical inefficiency. Both sets of results also suggest that Asian/Oceanic airlines are technically more efficient than European and North American airlines but that the differences are essentially due to more favourable environmental conditions. Nevertheless, it is among Asian companies that the major improvements in managerial efficiency (technical efficiency with environmental factors netted out) took place over the sample period (1977–1990). 相似文献

In this paper we present a new approach for solving the pricing equations (PDEs) of European call options for very general
stochastic volatility models, including the Stein and Stein, the Hull and White, and the Heston models as particular cases.
The main idea is to express the price in terms of a power series of the correlation parameter between the processes driving
the dynamics of the price and of the volatility. The expansion is done around correlation zero and each term is identified
via a probabilistic expression. It is shown that the power series converges with positive radius under some regularity conditions.
Besides, we propose (as in Alós in Finance Stoch. 10:353–365, 2006) a further approximation to make the terms of the series easily computable and we estimate the error we commit. Finally we
apply our methodology to some well-known financial models.

Endogenous location leadership 总被引:2,自引:0,他引:2
We analyze a game of timing where Sellers, which have marginal production cost asymmetries, can delay entry and a commitment to a location in a Hotelling type setting. When cost differences are large enough the game becomes a war of attrition that yields Stackelberg behavior where the high cost firm will delay choosing a location until the low cost firm commits to its position. We find interaction effects between timing and the degree of product differentiation and compute timing/location and mixed strategy equilibria through a range of marginal cost differences. The firms maximally differentiate with moderate cost differences; with somewhat greater cost differences there is intermediate differentiation, and; with large cost differences there is a blockading monopoly. The low cost firm always commits to entry immediately whereas the high cost firm either enters immediately, shortly after the low cost leader, or never, depending on the cost differences. Finally, we find that in equilibrium the duopoly is sustained for a larger range of cost differentials and that differentiation is greater than the social optimum. 相似文献

This paper compares the economic questions addressed by instrumental variables estimators with those addressed by structural approaches. We discuss Marschak’s Maxim: estimators should be selected on the basis of their ability to answer well-posed economic problems with minimal assumptions. A key identifying assumption that allows structural methods to be more informative than IV can be tested with data and does not have to be imposed. 相似文献

I develop a stylized model of endogenous growth in which the level of financial depth influences an economy’s long-run growth. Financial depth is defined within the model as the ease with which investors can issue equity in the market on new units of capital. I assume that agents differ in the cost of undertaking investment projects and that there is a fixed distribution of such costs across the population. I theoretically identify channels through which financial depth influences growth, both positively and negatively. When considering a specific distribution of costs, I show that the net effect of financial depth on growth is non-monotonic. It depends on the shape of the distribution, as well as the level or stage of financial depth. The results of this paper help to rationalize some findings in the recent empirical literature on the non-monotonic effect of financial depth on long-run growth. The model is even capable of obtaining a negative effect of excessive financial depth on growth, a result that is also found in the empirical literature. 相似文献

This paper uses a non-overlapping generations model of endogenous growth to emphasize the effect of human capital’s heterogeneity
on economic growth. In addition to education, we present two different typologies of training. The first, technology-general,
is independent of R&D; the second, technology-specific, is connected to the success of innovative activities and it is only
provided to workers engaged in research. By extending Redding (Econ J 106:452–470, 1996), we demonstrate that human capital
composition is important in determining the probability of innovation and the economy’s growth rate. Moreover, the paper shows
that technology-general training avoids low development traps when R&D is absent. 相似文献

Patterns of international capital raisings 总被引:2,自引:0,他引:2
This paper documents several new patterns associated with firms issuing stocks and bonds in foreign markets that motivate the need for and help guide the direction of future research. Three major patterns stand out. (1) A large and growing fraction of capital raisings, especially debt issuances, occurs in international markets, but a very small number of firms accounts for the bulk of international capital raisings, highlighting the cross-firm heterogeneity in financial globalization. (2) Changes in firm performance following equity and debt issuances in international markets are qualitatively similar to those following domestic issuances, suggesting that capital raisings abroad are not intrinsically different from those in domestic markets. (3) Firms continue to issue securities both abroad and at home after accessing international markets, suggesting that international and domestic markets are complements, not substitutes. Existing theories do not fully account for these patterns. 相似文献

Development and implementation of customer solutions: A study of process dynamics and market shaping
Sergio Biggemann Christian Kowalkowski Jane Maley Staffan Brege 《Industrial Marketing Management》2013
A broad, dynamic network perspective on solution processes remains scarce. This article presents the process of developing and implementing customer solutions and its effects on the wider business environment by investigating customers and suppliers in the global mining industry (Australia, Chile, and Sweden), analyzing the deployment of a new customer solution, and assessing the changes to the competitive environment and focal firms' relationships with other customers and suppliers. It shows that the forces that drive customer and supplier interests and motivation to co-develop customer solutions may change over time, thus redefining the aim and scope of solutions and creating failure risks. Customers present problems; suppliers respond, on the basis of not only the feasibility of the customer-specific solution but also of their evaluation of future solutions in a broader market; then suppliers aim to standardize successful solutions across markets. Customers want close supplier relationships and unique solutions but also like standardized and repeatable solutions, so they can share development costs with competitors and expose the supplier to competition to avoid lock-in effects. From a network perspective, a novel solution can have a market-shaping effect and evoke reactions from other actors who want to enhance their market position. However, these changes are not necessarily deliberate, and the dynamics that market introductions of solutions trigger may be difficult to predict. 相似文献

This paper studies the investment decisions of Spanish households using a unique data-set, the Spanish Survey of Household Finance (EFF). We propose a theoretical model in which households, given a fixed investment in housing, allocate their net wealth across bank time deposits, stocks and mortgage. Besides considering housing as an indivisible and illiquid asset that restricts the portfolio choice decision, we take into account the financial constraints that households face when they apply for external funding. For every representative household in the EFF, we solve this theoretical problem and obtain the theoretically optimal portfolio that is then compared with households’ actual choices. We find that households significantly under-invest in stocks and deposits while the optimal and actual mortgage investments agree. Considering the three types of financial assets at once, we find that the households headed by highly financially sophisticated, older, retired, richer, and unconstrained persons are the ones investing more efficiently. 相似文献

The technology set involved in the estimation of a multi-output production frontier theoretically implies monotonicity on outputs. This is because an efficient firm cannot reduce the vector of outputs holding the vector of inputs fixed while it still belongs to the frontier. In empirical studies dealing with the estimation of parametric distance functions, this hypothesis is often violated by observations with far from average characteristics. To overcome this limitation, we propose a new approach for allowing the easy imposition of monotonicity on outputs in this context. This methodology is tested in the educational sector using Spanish student level data from the Programme for International Student Assessment (PISA) database. The results indicate that a nonnegligible 8.33% of the production units break the monotonicity assumption. Furthermore, although there is no statistically significant difference in efficiency distribution by school ownership, our methodology helps to detect a slight worse mathematical performance for students attending public schools. 相似文献
