Opening the black box: Finding the source of cost inefficiency 总被引:2,自引:0,他引:2
Santiago Carbó Valverde David B. Humphrey Rafael López del Paso 《Journal of Productivity Analysis》2007,27(3):209-220
Parametric and nonparametric procedures are used to identify the apparent source of cost inefficiency in banking. Inefficiencies
of 20–25% from earlier studies are reduced to 1–5% when, in addition to commonly specified cost function influences, variables
reflecting banks’ external business environment and industry indicators of “productivity” are added. These productivity indicators
explain most of the reduction in bank operating cost over 1992–2001 and was 5 times the reduction in the dispersion of inefficiency.
Inefficiency appears stable over time because it is small relative to industry-wide cost changes occurring concurrently and
because technology dispersion is imperfect.

In this paper, we empirically assess the importance of regional and sector-specific determinants of industry dynamics. To
this aim we test three hypotheses (originally proposed by Shapiro and Khemani (1987, Int J Indust Organ 5:15–26)) for the
relationship between the entry and exit of firms: independence, symmetry and simultaneity. Estimates from a panel data system
of equations seem to confirm the simultaneity hypothesis for Spain, i.e. we find evidence of a displacement (replacement)
effect between the gross rate of entry (exit) and the gross rate of exit (entry). Also, our results show that, irrespective
of the hypothesis we use, both sectorial and regional variables affect entry and exit.

The aim of this paper is to analyze the determinants of the strategic environmental behavior of firms and, more specifically,
the external and internal barriers that limit and sometimes even prevent the environmental adaptation. The analysis focuses
on a sample of industrial firms that have at least three workers and that are located in Aragón, a region situated in the
northeast of Spain. In order to achieve this objective, first the theoretical literature on the topic is reviewed. Subsequently,
from the firms which were sampled, the existence of an underlying structure among the totality of barriers is studied. Finally,
this structure is analyzed in order to determine if it has any influence on the degree of proactivity of the firm’s environmental
strategy.

ABSTRACT: Sizeable employee share ownership plans (ESOPs) have been a unique feature of Ireland's privatization programme. Since the sale in 1999 of the national telecommunications operator, Eircom, the norm has been to allocate 14.9 per cent of equity to employees. We examine the role of the Eircom ESOP in the post‐privatization governance of the company. We find that the ESOP sought to maximize returns to employees as shareholders rather than behave in the interests of a wider set of stakeholders. This is explained in terms of the internal governance of the ESOP, namely its structure and rules, as well as the composition and motivations of the board of the ESOP Trustee. 相似文献

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices. 相似文献

We examine the use of subsidies to research and development (R&D) in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers, but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production; however, it does not lead to the equalization of per firm output and therefore to an efficient distribution of production costs. We also find that privatization of the public firm reduces R&D activity and welfare in the duopoly market. This result stands even when optimal R&D subsidies are provided. 相似文献

High rates of firm births and deaths are a pervasive phenomenon across industries and territories. Most studies have related the great turbulence at the fringe of practically all manufacturing industries to positive effects on the long-run performance of industries. According to these views business turbulence, although it has a relatively small incidence on net entry, leads to allocative improvement and stimulates innovation. The existing set of empirical studies does not reach clear conclusions, however, and many questions are still open. Our contribution analyses the relationship between business dynamics in manufacturing and the growth of total factor productivity in industries and regions. After a review of current literature on entry and exit it is argued that most models are tailored to suit the processes observed in industries and regions that are near the technological frontier, and we propose an approach that could be more representative of middle range economies such as Spain. According to this approach new firms are seen more as users of innovations than producers of innovations. We adopt a model based on a vintage capital framework in which new entrants embody the edge technologies available and exiting businesses are supposed to represent the most marginal obsolete plants. Both industries and regions are represented by a Hall's type production function which controls for imperfect competition and economies of scale. The results show that both entry and exit rates contribute positively to the growth of total factor productivity in industries and in regions. 相似文献

In this paper, a structural analysis of hybrid censoring models is presented. This new modularization approach to hybrid censoring models enables a convenient derivation of distributional results. For instance, it allows to derive the exact distribution of the MLEs under an exponential assumption for very complex hybrid scenarios. In order to illustrate the benefit of this idea, we apply it to four new unified progressive hybrid censoring schemes. They are extensions of already proposed unified Type-I/II/III/IV hybrid censoring schemes to progressively Type-II censored data. The resulting analysis shows that the modularization approach provides a powerful, efficient, and elegant tool to study even more complex hybrid censoring models. 相似文献

The objective of this research is to examine the role of sector-specific information technology (IT) developments and their significance in terms of the revenue and earnings before tax of Logistics Service Providers (LSPs), as well as the impact of these developments on the flexibility and integration of LSPs. A survey questionnaire was conducted with 284 LSPs participants. The data provided by the 51 responding enterprises provided a representative sample for the analysis of the sample population and the drawing of general and relevant conclusions related to basic population. It can be concluded that their revenue, earnings before tax and degree of integration into the supply chain depend on the sector-specific IT developments carried out by the given enterprise. IT investments will remain important in the future and the introduction and leveraging the best technologies may yield competitive advantages and higher financial rewards for LSPs. 相似文献
