In this paper, the recently developed panel unit root and the Pedroni cointegration tests are applied to empirically examine
the validity of the Feldstein–Horioka puzzle (F–H puzzle) for a heterogeneous panel of 14 Latin American and five Caribbean
countries over the period, 1960–2002. The findings indicate that in these countries, the long-run solvency condition is maintained.
Finally, employing the Pedroni panel group FM-OLS estimator (2000, 2001), it is found that the statistically significant estimated
savings-retention coefficient for the panel is relatively small indicating that the F–H Puzzle is not valid and thus implying
the prevalence of a moderate degree of capital mobility.

We here critique the articles by Dmitruk & Koshevoy (1991, J Econ Theory 55:121–144) and by Bol (1986, J Econ Theory 38:380–385)
by showing how to solve the examples they erected to show the non-existence of functions for evaluating performance efficiencies
in DEA. We also show that functions satisfying these criteria—and other important criteria as well—were already available
prior to the publications of D&K and by Bol and have since been greatly extended to increase the power and scope of DEA.

Productivity and efficiency of state-owned enterprises in China 总被引:1,自引:0,他引:1
Feng-Cheng Fu Chu-Ping C. Vijverberg Yong-Sheng Chen 《Journal of Productivity Analysis》2008,29(3):249-259
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.

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.

This study analyzes the relationship between entrepreneurial dynamics in Latin-American countries and the level of competitiveness
these countries show. Based on the research conducted by Wennekers et al. [Small Business Economics, 24(3):293–309, 2005] that demonstrates a U-shaped relationship between the country’s rate of entrepreneurship and its level
of competitiveness and economic development, we hypothesize that Latin-American countries have a descending behaviour under
the U-shaped curve approach. The results from three regression models support this hypothesis and suggest that competitiveness
and economic growth deter entrepreneurial dynamics on Latin-American countries. We discuss that Latin-American countries need
to improve some structural factors to achieve a high level of entrepreneurial dynamics.

Cost efficiency of Slovenian water distribution utilities: an application of stochastic frontier methods 总被引:2,自引:1,他引:1
Massimo Filippini Nevenka Hrovatin Jelena Zorić 《Journal of Productivity Analysis》2008,29(2):169-182
This study estimates cost inefficiency and economies of scale of Slovenian water distribution utilities over the 1997–2003
period by employing several different stochastic frontier methods. The results indicate that significant cost inefficiencies
are present in the utilities. An introduction of incentive-based price regulation scheme might help resolve this problem.
However, the inefficiency scores obtained from different cost frontier models are not found to be robust. The levels of inefficiency
estimates as well as the rankings depend on the econometric specification of the model. The established lack of robustness
can be at least partly explained by different ability of the models to separate unobserved heterogeneity from inefficiency.
Newly proposed true fixed effects model (Greene, J Econom 126:269–303, 2005; J Prod Anal 23(1):7–32, 2005) appears to perform
better than the conventional panel data models with respect to distinguishing between unobserved heterogeneity and inefficiency.
On the other hand, different models produce fairly robust results with respect to estimates of economies of output density,
customer density and economies of scale. The optimal size of a company is found to closely corresponds to the sample median.
Economies of scale are found in small-sized utilities, while large companies exhibit diseconomies of scale.

The question of whether a technology exhibits particular properties such as radial input or output homotheticity is a crucial
one for a producer since it should strongly impact on its reactions to market changes. Primont and Primont (Econ Lett 45:191–195,
1994) established that it can be tested using only weak assumptions. They further used their results to test for input homotheticity
of an educational production technology (Primont and Primont, Can J Econ 29:587–591, 1996). In this paper, it is shown that
if not implemented properly, the test can lead to biased results. Some ways to obtain unbiased results are also suggested.

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.

Are some Indian banks too large? An examination of size efficiency in Indian banking 总被引:1,自引:0,他引:1
Subhash C. Ray 《Journal of Productivity Analysis》2007,27(1):41-56
In this paper we use data from the years 1997–2003 to evaluate the size efficiency, as distinct from scale efficiency, of
Indian banks. Following Maindiratta [Maindiratta A (1990) J Econ 46:39–56] we consider a bank to be “too large” if breaking
it up into a number of smaller units would result in a larger output bundle than what could be produced from the same input
by a single bank. When this is the case, the bank is not size efficient. Our analysis shows that many of the banks are, indeed,
too large in various years. We also find that often a bank is operating in the region of diminishing returns to scale but
is not a candidate for break up.

This study introduces an Environmental Performance Index (EPI) to assess the performance of firms that produce both good and bad outputs. In the one good output one bad output case, the EPI simplifies to the ratio of good–bad output for period t + 1 and period t. After deriving the index, data for U.S. coal-fired power plants from 1985 to 1998 are used to demonstrate insights that the EPI can provide. We find that power plants with units participating in Phase I of the Acid Rain Program experience a dramatic improvement in their EPI during 1994–1995.

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.

Extant empirical literature does not provide abundant evidence for the information content hypothesis regarding firm-level
dividend signaling. Although this is consistent with the argument against an optimal firm-level dividend policy, this does
not imply an absence of an optimal aggregate dividend level. Aggregate dividends and earnings may exhibit stronger associations
if aggregation filters out firm-specific earnings information and indicates macroeconomic trends. Using macroeconomic data,
we show that aggregate payout ratios signal aggregate future earnings growth for horizons up to 4 years, and that excess aggregate
liquidity plays an important role in this relationship.

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.

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.

The impact of patents and standards on macroeconomic growth: a panel approach covering four countries and 12 sectors 总被引:1,自引:0,他引:1
Based on the assumption that codified technological know-how contributes to economic growth, this paper presents the estimation
of a Cobb–Douglas production function, pooling data from four European countries and 12 sectors. The empirical results confirm
that both the stock of patents and the stock of technical standards contribute significantly to economic growth in the 1990s.
Whereas the results of the country models are rather similar, we observe significant differences between the sector models,
which indicate that standards are more important for growth in less R&D-intensive industries and patents in R&D-intensive
industries.

The effects of court-ordered education finance reform on property values and residential choice have received increasing attention
in recent years (Fischel 2001). However, little attention has been focused on the effects of education finance reform on manufacturing
sector property values within an optimizing framework. This is pursued here by modeling education expenditures and education
finance reform as “free” variables to manufacturing firms in a cost function model together with input demand equations. This
framework is applied to panel data on manufacturers’ capital (building and structures) stocks for the 48 continental US for
1982–1996 to estimate implicit (shadow) values to the manufacturing sector of education spending and school finance reform.
On average, school finance reform lowers the implicit value of manufacturing firms’ stock of buildings and structures capital,
while greater education spending lowers manufacturing variable costs.

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%.

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.

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.

Technical efficiency in farming: a meta-regression analysis 总被引:1,自引:0,他引:1
Boris E. Bravo-Ureta Daniel Solís Víctor H. Moreira López José F. Maripani Abdourahmane Thiam Teodoro Rivas 《Journal of Productivity Analysis》2007,27(1):57-72
A meta-regression analysis including 167 farm level technical efficiency (TE) studies of developing and developed countries
was undertaken. The econometric results suggest that stochastic frontier models generate lower mean TE (MTE) estimates than
non-parametric deterministic models, while parametric deterministic frontier models yield lower estimates than the stochastic
approach. The primal approach is the most common technological representation. In addition, frontier models based on cross-sectional
data produce lower estimates than those based on panel data whereas the relationship between functional form and MTE is inconclusive.
On average, studies for animal production show a higher MTE than crop farming. The results also suggest that the studies for
countries in Western Europe and Oceania present, on average, the highest levels of MTE among all regions after accounting
for various methodological features. In contrast, studies for Eastern European countries exhibit the lowest estimate followed
by those from Asian, African, Latin American, and North American countries. Additional analysis reveals that MTEs are positively
and significantly related to the average income of the countries in the data set but this pattern is broken by the upper middle
income group which displays the lowest MTE.
