This paper investigates the technical efficiency of labor market matching from a stochastic frontier approach. The true fixed-effects
model (Greene J Prod Anal 23:7–32, 2005a; J Econom 126:269–303, 2005b) is utilised in order to separate cross-sectional heterogeneity from inefficiency, and inefficiency terms are modelled following
Battese and Coelli (Empir Econ 20:325–332, 1995). The data set consists of almost 17,000 observations from Local Labor Offices (LLOs) in Finland. According to the results,
there are notable differences in matching efficiency between regions, and these differences contribute significantly to the
number of filled vacancies. If all regions were as efficient as the most efficient one, the number of total matches per month
would increase by over 23%. The heterogeneity of the job-seeker stock is an important determinant of matching efficiency:
the weight of the composition of the job-seeker stock in the inefficiency terms is on average 85%.

A method is presented for classifying strongly efficient units in DEA as interior or exterior, and as self-evaluators or active
peers. The exterior strongly efficient units are found by running the enveloping procedure “from below”. There is no firm
production-function evidence of the efficiency of exterior self-evaluators. Interior self-evaluators are more likely to have
active peers as neighbours in more directions and may therefore represent technology. When performing a second stage regression
analysis of efficiency scores, exterior self-evaluators should be removed. The proportion of exterior active peers also provides
information on whether the variable specification is supported by the data.

In this paper we develop a test of infinite order degree stochastic dominance based on the use of the empirical Laplace transform
function. Two applications are considered. One uses the income data of Anderson (Econometrica 64:1183–1193, 1996) and derives results consistent with his. In the other application we examine the dominance between the U.S. and U.K. stock
markets. Using data on the S&P 500 and the FTALL-Share we show that the U.S. displays infinite order degree stochastic dominance
of the U.K.

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.

We use the multivariate extension of Exponential Generalized Autoregressive Conditionally Heteroscedastic (EGARCH) of Nelson,
Econometrica, 59: 347–370, 1991 to test for spillover effects and examine the extent of asymmetries between short- and long-term interest rates and portfolios
of money center, large, and medium-size banks in the U.S. Our results indicate the existence of price and volatility spillovers
from short- and long-term interest rates to the three bank portfolios. We also provide evidence of response asymmetries for
the portfolios of money center and large banks, suggesting that money center and large banks are more sensitive to negative
than positive short- and long-term interest rate changes.

Productivity and efficiency of state-owned enterprises in China 总被引:1,自引:0,他引:1

The purpose of this paper is to evaluate the variations in SOE efficiency and productivity from the perspectives of macroeconomic
fluctuations and systematic reform in China during 1986–2003. We use Data Envelopment Analysis to measure SOE efficiency.
Subsequently, we use the Malmquist Index of Productivity change to measure productivity growth. The empirical results show
that SOE efficiency and productivity exhibited obvious improvements during periods of strong systematic reform and a prosperous
economy. The systematic reform after 1998 had a clear-cut impact on SOE performance.

This paper presents a new test of the permanent income hypothesis in five major industrial countries. The test first decomposes
consumption and income into their long run trend (permanent) and short run cyclical (transitory) components, using the recently
developed multivariate stochastic detrending approach developed by Vahid and Engle (1997), among others. This approach exploits the presence of possible common stochastic trends and cycles among the variables in
the system to arrive at a more efficient decomposition of these variables. Using the decomposition results, and in contrast
to many articles in the literature, the paper finds support for the permanent income hypothesis. Specifically, the paper finds
that, while permanent consumption is related to permanent income, transitory consumption is related to neither permanent nor
transitory income.

Ukraine’s recent elections revealed deep divisions between eastern regions, which favored central economic planning, and western
regions, which preferred more free market reforms. This study compares polyclinics in Ukraine to see if the inflexibility
of Soviet-style planned economies results in lower economic efficiency in eastern regions. Using data from two geopolitical
regions, Data Envelopment Analysis (DEA) scores for polyclinic efficiencies are modeled as a function of demographic and economic
determinants. Surprisingly, results indicate that polyclinics in western Ukraine are less efficient. Possible explanations,
including case mix intensity, responsiveness to local preferences, physician entrepreneurial behavior and a legacy of inequitable
funding, are discussed.

An examination of the performance and prospects for the future of internet-primary banks 总被引:1,自引:0,他引:1
We study Internet-primary banks for differences in performance versus newly chartered traditional banks from 1996 through
2003. Internet-primary banks are larger, with lower net interest margins and loan losses, and higher wage and physical capital
rates than newly chartered traditional banks. Univariate ROE is lower, but profit efficiency is significantly higher on average
for Internet-primary banks compared to all newly chartered banks as well as those that survive through the sample period.
In multivariate models, Internet-primary banks continue to have significantly higher average profit efficiency, and particularly
so when of sufficient size.

This paper examines the banking efficiency in a pre- and post-liberalization environment by drawing on the Turkish experience
by using DEA. The paper also investigates the scale effect on efficiency. Our findings suggest that liberalization programs
were followed by an observable decline in efficiency. Another finding of the study is that the Turkish banking system had
a serious scale problem during the study period. The second part of our analysis relied on econometric methods and found that
one major reason for such system-wide efficiency decline has been the growing macroeconomic instability of the Turkish economy
in general and financial sector in particular.

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.

We present and discuss measures for analyzing productivity in deterministic frontier models. A new efficiency measure is introduced
allowing for discrimination among efficient organizational units. In addition, a new performance measure for analyzing productivity of organizational units is presented. This measure fulfills various properties of efficiency measures
but relaxes the indicator property. Both new approaches are based on the development of efficiency vectors which is a new vector measure for measuring efficiency. The vector components are efficiency measures related to subsets
of a production possibility set. The new approaches are applied in the context of data envelopment analysis.

Efficient frontier estimation: a maximum entropy approach 总被引:1,自引:0,他引:1
An alternative efficiency estimation approach is developed utilizing generalized maximum entropy (GME). GME combines the strengths
of both SFA and DEA, allowing for the estimation of a frontier that is stochastic, without making an ad hoc assumption about
the distribution of the efficiency component. GME results approach SFA results as the one-sided inefficiency bounds used by
GME shrink. Results similar to DEA are achieved as the bounds increase. The GME results are distributed like DEA, but yield
virtually the same rankings as SFA. The results suggest that GME may provide a link between various estimators of efficiency.

Determining the profit maximizing input–output bundle of a firm requires data on prices. This paper shows how endogenously
determined shadow prices can be used in place of actual prices to obtain the optimal input–output bundle where the firm’s
shadow profit is maximized. This approach amounts to an application of the Weak Axiom of Profit Maximization (WAPM) formulated
by Varian [(1984) The Non-parametric approach to production analysis. Econometrica 52:3 (May) 579–597] based on shadow prices rather than actual
prices. At these shadow prices, the shadow profit of a firm is zero. The maximum shadow profit that could have been attained
at some other input–output bundle is shown to be a measure of the inefficiency of the firm. Because the benchmark input–output
bundle is always an observed bundle from the data, it can be determined without having to solve any elaborate programming
problem.

The paper investigates the measurement of economic efficiency under transaction costs in a second best world. New measurements of technical efficiency, allocative efficiency, and price efficiency are proposed. They have three desirable properties. First, they measure efficiency loss in monetary units. Second, they are additive and can be conveniently summed into an overall efficiency measure. Third, they allow for transaction costs and their effects on prices and trade incentives. The paper investigates the welfare effects of technology choice, government pricing and trade policy, and market imperfections on efficiency. It provides new insights on the measurement of benefits from trade liberalization when trade affects not only price efficiency, but also technical and allocative efficiency.

In this paper we propose a target efficiency DEA model that allows for the inclusion of environmental variables in a one stage model while maintaining a high degree of discrimination
power. The model estimates the impact of managerial and environmental factors on efficiency simultaneously. A decomposition
of the overall technical efficiency into two components, target efficiency and environmental efficiency, is derived. Estimation
of target efficiency scores requires the solution of a single large non-linear optimization problem and provides both a joint
estimation of target efficiency scores from all DMUs and an estimation of a common scalar expressing the environmental impact
on efficiency for each environmental factor. We argue that if the indices on environmental conditions are constructed as the
percentage of output with certain attributes present, then it is reasonable to let all reference DMUs characterized by a composed
fraction lower than the fraction of output possessing the attribute of the evaluated DMU enter as potential dominators. It
is shown that this requirement transforms the cone-ratio constraints on intensity variables in the BM-model (Banker and Morey
1986) into endogenous handicap functions on outputs. Furthermore, a priori information or general agreements on allowable handicap values can be incorporated into
the model along the same lines as specifications of assurance regions in standard DEA.

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.

Measuring performance in the presence of stochastic demand for hospital services: an analysis of Belgian general care hospitals 总被引:1,自引:1,他引:0
Mike Smet 《Journal of Productivity Analysis》2007,27(1):13-29
Since demand for hospital services is subject to substantial variability, the relationship between uncertain demand, excess
capacity, hospital costs and performance should be investigated thoroughly. In this paper a waiting time indicator to proxy
hospital standby capacity is incorporated into a multi-product translog cost function for Belgian general care hospitals.
The indicator is derived from queuing theory and improves on the conventionally used (inverse of the) occupancy rate. The
multi-product stochastic frontier specification allows calculation of cost elasticities and marginal cost of seven hospital
departments, as well as the degree of economies of scale and scope and enables identification of differences in efficiency.

In this paper we argue that the standard approach for measuring output and productivity in the trade sector has become obsolete.
The key problem is that changes in prices of goods purchased for resale are not accounted for. We outline a consistent accounting
framework for measuring trade productivity and provide new estimates, taking into account purchase prices of goods sold in
a double deflation procedure. We find strong productivity improvements in the UK and US compared to France, Germany and The
Netherlands since the mid-1990s. This finding is robust for various productivity measurement models.

This study examines economic performance, environmental performance, and regulatory activity for plants in three industries: pulp and paper, oil, and steel. Stochastic frontier production function models show significant deviations from production efficiency. Older plants are less efficient in production, but perform no worse on emissions. Plants spending more on pollution abatement tend to do worse on both production efficiency and emissions. Stricter local regulatory pressure is associated with somewhat lower emissions, but has mixed effects on production efficiency. Positive correlations between SUR residuals for emissions and production efficiency suggest unmeasured plant-level characteristics that drive both economic and environmental performance.
