This study measures productivity growth on Irish dairy farms over the period 1984–2000. A total factor productivity index
is constructed for the dairy system and is decomposed into technical change, efficiency change, and changes in scale efficiency.
This is achieved by estimating a stochastic output distance function model of the production technology in use on Irish dairy
farms. Overall, productivity on Irish dairy farms grew by 1.2% per annum over the sample period.

Sources of profit change for Telstra, Australia’s largest telecommunications firm, are examined. A new method allows for changes, in a firm’s profits to be broken down into separate effects due to productivity change, price changes, and growth in the firm’s size. This in turn allows us to calculate the distribution of the benefits of productivity improvements between consumers, labor, and shareholders. The results show that around half the benefits from Telstra’s productivity improvements from 1984 to 1994 were passed on to consumers in the form of real price reductions.

In this paper, we analyse the nature of the relationship between market power and technical efficiency for producers’ cooperatives.
More specifically we test two hypotheses: first, we evaluate the extent to which increasing market pressure may help producers’
cooperatives to improve technical efficiency to guarantee positive profits; second, we test whether higher technical efficiency
induces producers’ cooperatives to have a larger market share. These hypotheses are tested on a sample of Italian conventional
and cooperative firms for the Wine Production and Processing sector, using both frontier analysis and dynamic panel techniques.
The results support the hypothesis that increasing market pressure can affect positively the cooperatives′ efficiency, while
gains in technical efficiency do not seem to have any impact on the cooperatives’ market share.

This paper analyzes the productivity of farms across 370 municipalities in the Center-West region of Brazil. A stochastic
frontier model with a latent spatial structure is proposed to account for possible unknown geographical variation of the outputs.
The paper compares versions of the model that include the latent spatial effect in the mean of output or as a variable that
conditions the distribution of inefficiency, include or not observed municipal variables, and specify independent normal or
conditional autoregressive priors for the spatial effects. The Bayesian paradigm is used to estimate the proposed models.
As the resultant posterior distributions do not have a closed form, stochastic simulation techniques are used to obtain samples
from them. Two model comparison criteria provide support for including the latent spatial effects, even after considering
covariates at the municipal level. Models that ignore the latent spatial effects produce significantly different rankings
of inefficiencies across agents.

Various studies have focused on the reasons for franchising. Most studies have concentrated principally on the franchisors’ motivations for franchising, with only a few exploring franchising as a route to self-employment. This paper seeks to provide a conceptual framework which examines the value of franchising to franchisees, employing an intellectual capital perspective. It is suggested that the (perceived) value of the franchise system is unlikely to remain static over time, and that the perceived benefits of franchise systems will vary according to both system and franchisee attributes.

Port workers services have been usually heavily regulated and reserved exclusively for a special kind of workers, dockworkers,
which seems to have been the cause of serious inefficiencies worldwide. During the eighties, law reforms have been introduced
to solve this problem. In this paper we analyze and decompose efficiency in cargo handling operations in 19 Spanish ports
from 1990 to 1998. The method chosen is that of the parametric estimation of both allocative and technical inefficiency using
panel data and a quadratic cost function. Results show that although inefficiency has decreased overall, there has been over
utilization of labor regarding capital, and technical inefficiency. This supports the need of further consideration of other
aspects including competition.

Debreu’s coefficient of resource utilization is freed from individual data requirements. The procedure is shown to be equivalent
to the imposition of Leontief preferences. The rate of growth of the modified Debreu coefficient and the Solow residual are
shown to add up to TFP growth. This decomposition is the neoclassical counterpart to the frontier analytic decomposition of
productivity growth into technical change and efficiency change. The terms can now be broken down by sector as well as by
factor input.

The methodologies that have been used in existing research to assess the efficiency with which organic farms are operating
are generally based either on the stochastic frontier methodology or on a deterministic non-parametric approach. Recently,
Kumbhakar et al. (J Econom 137:1–27, 2007) proposed a new nonparametric, stochastic method based on the local maximum likelihood
principle. We use this methodology to compare the efficiency ratings of organic and conventional arable crop farms in the
Spanish region of Andalucía. Nonparametrically encompassing the stochastic frontier model is especially useful when comparing
the performance of two groups that are likely to be characterized by different production technologies.

In this paper, we estimate parametric input and output distance functions and discuss how to estimate a mixture/latent class
model (LCM) involving the output and input distance functions in the context of multi-input and multi-output production technology.
The proposed technique is applied to a panel data on European Railways (1971–1994). This model allows us to identify determinants
of the efficiency orientation, thereby providing useful information that can help researchers to choose between the input
and the output-oriented approaches. In addition, we develop cross-indices that can be used to compute input (output) technical
inefficiency from the estimates of output (input) distance function.

Application of a double bootstrap to investigation of determinants of technical efficiency of farms in Central Europe 总被引:1,自引:1,他引:0
The paper provides one of the first applications of the double bootstrap procedure (Simar and Wilson 2007) in a two-stage estimation of the effect of environmental variables on non-parametric estimates of technical efficiency.
This procedure enables consistent inference within models explaining efficiency scores, while simultaneously producing standard
errors and confidence intervals for these efficiency scores. The application is to 88 livestock and 256 crop farms in the
Czech Republic, split into individual and corporate.

This paper considers the measurement of performance in public service provision in an international context by examining outcome-based
measures for the education sector. It first sets out the measurement issues in general terms. The paper then applies these
methods to comparing the UK experience with that in the US over the period 1979–2002. The results show higher labour productivity
growth in the UK education sector than in the US over this time period, so that the UK eliminated the productivity gap with
the US by the end of the Century.

The Relationship Among Union Membership, Facets of Satisfaction and Intent to Leave: Further Evidence on the Voice Face of Unions 总被引:1,自引:0,他引:1
Steven E. Abraham Barry A. Friedman Randall K. Thomas 《Employee Responsibilities and Rights Journal》2008,20(1):1-11
This study examined the impact of union membership on employees’ intent to leave their jobs across a number of facets of satisfaction,
as a further test of unions’ voice face. Among the findings were that there were significant relationships between job, compensation,
benefits, working conditions, and immediate supervisor satisfaction and intent to leave one’s job for nonunion employees.
In contrast, only the relationship between job satisfaction and intent to leave was significant for union employees. Finally,
over the facets of satisfaction where one would expect unions to have the most influence, the relationship between intent
to leave one’s job and satisfaction was greater for nonunion employees than for union employees. These results provide a great
deal of support for the effect of unions’ voice face.

Decompositions of total factor productivity (TFP) shed light on the driving factors behind productivity change. We develop
the first exact decomposition of the Fisher ideal TFP index which contains no debatable mixed-period components or residuals.
We systematically isolate five effects of (1) technical change, (2) technical efficiency, (3) scale efficiency, (4) allocative
efficiency, and (5) price effect. The three efficiency components (2–4) represent the efficiency of achieving a given target
point. Components (1) and (5) capture the changes of the target point. While the technical change component is well-established,
changes in the relative input–output prices can have real effects on the scale and scope of the target. Such changes are captured
by the new price effect component (5). The new decomposition is compared with existing decompositions both in theory and by
means of an empirical application to a panel data of 459 Finnish farms in years 1992–2000.

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.

Investment and dynamic DEA 总被引:1,自引:0,他引:1
A dynamic version of data envelopment analysis (DEA) is developed in the present paper. Our model introduces investment in
traditional DEA and imposes intertemporal cost minimization. Adding an intertemporal adjustment constraint into the cost minimization
problem, we derive the relation between the DEA variables of the variable cost function and those of the primary production
frontiers’ coefficients. The augmented DEA model can be solved using standard linear programming. This dynamic framework enables
computing the production frontiers, measuring the productive efficiencies and evaluating the potential economies all in the
presence of adjustment costs.

Many observers argued that Barack Obama’s candidacy in the U.S. presidential election of 2008 benefited from the financial
crisis and recessionary economic conditions which voters blamed on the Republican administration. However, an empirical examination
of stock price and public opinion data indicates that improvements in Obama’s electoral prospects led stock price declines
and that gains by Obama were more likely to be followed by falling stock prices than by rising prices. This evidence suggests
that the poor performance of the stock market in the days leading up to Obama’s victory was partly caused by, rather than
causing, Obama’s success.

The paper considers how to measure capital in a model where technical progress is embodied in new units of capital. This embodiment
model also assumes that once new units of capital are installed, it cannot be “unbolted” and sold on the second hand market.
A significant difference between this Solow–Harper model and the traditional capital services model due to Jorgenson and his
coworkers is that rising real wage rates will generally induce early retirement of assets; i.e., this model can provide an
explanation for obsolescence. The paper studies how to aggregate over vintages and how to measure depreciation in the context
of this embodiment model. These problems are more complicated than the corresponding problems in the traditional capital services
model because the age of retirement of an asset is endogenous in the embodiment model. The paper uses duality theory to simplify
the exposition.

The impact of desirability and feasibility on entrepreneurial intentions: A structural equation model 总被引:2,自引:1,他引:1
Maribel Guerrero Josep Rialp David Urbano 《The International Entrepreneurship and Management Journal》2008,4(1):35-50
There is general agreement that attitudes towards entrepreneurship are determinant factors to decide to be an entrepreneur.
In this context, this research is focused on analyzing the relationship between desirability and feasibility on university
student’s intentions to create a new firm in Catalonia. A structural equation model supported by Krueger & Brazeal’s Model
was tested with different groups of students. The main results reveal most of university students consider desirable to create
a new firm, although the perception of feasibility is not positive. Also, there is a statistical significant and positively
relationship between credibility and the intention to create a new firm.

The 1981 PATCO strike stands out as a symbol of union decline. The penchant to stigmatize PATCO detracts from important aspects of the union’s unorthodox strategy. Preparations for 1981 negotiations were coordinated by rank-and-file activists who referred to themselves as ‘choir boys’. An extensive mobilization network cultivated by the ‘choir boys’ contributed to cohesiveness and in effect democratized PATCO. The union’s effectiveness in building internal solidarity was its most notable accomplishment. Twenty-first-century labor-movement revitalization will require not only strong, creative leadership but also rank-and-file mobilization in the mold of PATCO’s ‘choir boy’ system. It is this type of grassroots activism that has the potential to promote an internal culture of militant action which can serve as the foundation for union growth.

This study evaluates the Federal Reserve forecasts of manufacturing capacity utilization employing, as benchmarks, the forecasts
from a univariate model which utilizes past information in capacity utilization, and from a bivariate model which utilizes
past information in both capacity utilization and the federal funds rate. In addition to accurately predicting the directional
change in capacity utilization, the Federal Reserve forecasts are “weakly” rational and generally superior to the bivariate
forecasts. In light of another finding that monetary policy is non-neutral, we argue the Federal Reserve forecasts of capacity
utilization have positively contributed to the Fed’s success in maintaining a low inflationary environment.
