Introduction
Small and medium-sized enterprises (SMEs) and private entrepreneurship are pivotal to the
economic fabric of both developed and developing countries. They contribute significantly to
employment, innovation, and the diversification of economic activities. In many economies,
SMEs account for a substantial portion of employment and GDP. For instance, in the European
Union, SMEs represent over 99% of all businesses and employ around two-thirds of the
workforce.

Assessing the economic efficiency of these entities is crucial for policymakers, investors, and the
entrepreneurs themselves. Efficient SMEs are more likely to survive economic downturns,
expand their operations, and contribute positively to the economy. Conversely, inefficiencies can
lead to resource wastage, reduced competitiveness, and eventual business failure
1
.
Economic efficiency in SMEs encompasses various dimensions, including technical efficiency,
allocative efficiency, and cost efficiency. Technical efficiency refers to the ability of a firm to
obtain the maximum output from a given set of inputs, while allocative efficiency pertains to the
optimal allocation of resources to maximize profit. Cost efficiency combines both technical and
allocative efficiencies, focusing on minimizing costs for a given output level.
This article aims to explore and compare the primary statistical methods employed to evaluate
the economic efficiency of SMEs and private entrepreneurship. By examining these methods, we
seek to provide insights into their applicability, strengths, and limitations in assessing SME
performance.
Methods.
To understand the statistical assessment of economic efficiency in SMEs, we
reviewed and analyzed several prominent methodologies:
1.
Data envelopment analysis (DEA)
DEA is a non-parametric method used to evaluate the efficiency of decision-making units
(DMUs) by comparing them to a constructed frontier of best practices. It calculates efficiency
scores by solving linear programming problems that maximize the ratio of weighted outputs to
weighted inputs, subject to the constraint that the same ratio for all DMUs does not exceed one.
DEA is particularly useful for assessing relative efficiency when multiple inputs and outputs are
involved. It does not require a predefined functional form for the production process, making it
flexible and widely applicable. Example: A study on Turkish SMEs utilized DEA to assess their
efficiency, considering inputs like liabilities and equity, and outputs such as sales revenue and
net profit. The results highlighted variations in efficiency across firms, providing insights into
areas for improvement
2
.
2.
Stochastic frontier analysis (SFA)
SFA is a parametric approach that estimates the production frontier while accounting for random
errors and inefficiencies. It involves specifying a functional form for the production process and
decomposing the error term into two components: one representing random noise and the other
capturing inefficiency.
SFA allows for the estimation of efficiency scores and the identification of factors influencing
inefficiency. It is particularly useful when there is a need to model the production process
explicitly and when data are subject to stochastic variations. Example: Research on SMEs in
Mexico applied SFA to estimate technical inefficiency, finding that factors like firm age and
technology adoption influenced efficiency levels.

3.
Regression-based models
Regression analysis, including panel data models, is commonly used to examine the relationship
between efficiency and various determinants. These models can control for unobserved
heterogeneity and temporal dynamics, providing insights into how factors like firm size, age, and
capital structure affect efficiency
3
. Example: A study on Spanish SMEs employed regression
models to analyze the impact of firm characteristics on profitability, revealing that smaller firms
tend to be less efficient due to scale disadvantages.
4.
Cost–benefit analysis (CBA)
CBA is a systematic approach to evaluating the economic feasibility of projects or investments
by comparing the total expected costs against the total expected benefits. It involves quantifying
and monetizing all relevant costs and benefits over the project's lifespan. In the context of SMEs,
CBA can be used to assess the viability of new ventures, expansion plans, or technological
investments, aiding in decision-making processes. Example: A feasibility study for a proposed
SME development program utilized CBA to determine its potential economic impact, concluding
that the benefits outweighed the costs.
5.
Total factor productivity (TFP) analysis
TFP measures the efficiency with which all inputs are used to produce output. It is calculated as
the ratio of aggregate output to a weighted average of inputs. TFP growth indicates
improvements in efficiency and technological progress. Example: An analysis of SMEs in
Kazakhstan employed TFP to assess productivity changes over time, finding that technological
advancements contributed significantly to productivity growth.
Results.
The application of various statistical methods has provided comprehensive insights
into the economic efficiency of small and medium-sized enterprises (SMEs) and private
entrepreneurship. These methodologies have highlighted both the strengths and areas for
improvement within these businesses, offering valuable information for stakeholders
aiming to enhance performance and competitiveness.
a) Data envelopmenta analysis (DEA)
Data Envelopment Analysis (DEA) has been instrumental in benchmarking the relative
efficiency of SMEs across different sectors. For instance, a study by Kotey and O'Donnell (2014)
applied DEA to assess the efficiency of SMEs in the Australian food, beverages, and tobacco
manufacturing industry. The findings indicated that, on average, firms could produce the same
level of output using approximately 20% fewer inputs. Additionally, the study revealed that
firms could achieve cost savings of around 32% by optimizing both the level and mix of inputs.
These results underscore the potential for significant efficiency improvements through better
resource utilization and management practices.

b) Stochastic frontier analysis (SFA)
Stochastic Frontier Analysis (SFA) has been employed to estimate the production frontier and
identify inefficiencies within SMEs. In a study by Basurto Hernández and Sánchez Trujillo
(2022), SFA was applied to data from over 28,000 SMEs in Mexico. The analysis revealed an
average technical efficiency (TE) of 54.6%, indicating that, on average, SMEs operate at just
over half of their potential efficiency. The study also found that SMEs with highly skilled
workers and those that utilized the internet in their production processes tended to have higher
levels of TE. Conversely, firms that allocated a higher proportion of their revenues to tax-related
expenses exhibited lower efficiency levels. These findings highlight the importance of human
capital and technological adoption in enhancing SME performance.
c) Regression models
Regression analysis has been utilized to examine the relationships between various firm
characteristics and their economic efficiency. A study by Pérez-Gómez et al. (2018) employed
stochastic profit frontier models to analyze SMEs in Spain. The results indicated that factors
such as firm size, capital intensity, and market competition significantly influenced profitability
and efficiency. Larger firms and those with higher capital intensity were found to be more
efficient, while increased market competition tended to reduce profitability. These insights
suggest that strategic decisions related to firm size and market positioning can impact the
economic efficiency of SMEs.
d) Cost–benefit analysis (CBA)
Cost–Benefit Analysis (CBA) has been a valuable tool in evaluating the economic viability of
projects and investments within SMEs. According to Investopedia, CBA involves estimating all
the costs associated with a decision and comparing them to the estimated benefits. This
comparison helps in assessing whether the benefits outweigh the costs, guiding investment
decisions. For example, a renovation project with an upfront cost of $50,000 and expected
benefits of $288,388 over three years would have a Benefit-Cost Ratio (BCR) of 5.77, indicating
substantial benefits over costs. However, it's essential to consider that relying solely on BCR can
be misleading, and it should be part of a broader decision-making process.
e) Total factor productivity (TFP) analysis
Total Factor Productivity (TFP) analysis has been employed to assess the efficiency with which
all inputs are used to produce output. A study by Basurto Hernández and Sánchez Trujillo (2022)
found that technological advancements and innovation were key drivers of productivity growth
in SMEs. Firms that invested in technology and innovation experienced higher TFP, leading to
improved efficiency and competitiveness. These findings emphasize the importance of
continuous investment in technology and innovation for sustaining long-term productivity
growth

These findings underscore the multifaceted nature of economic efficiency and the need for
comprehensive assessment methods to capture its various dimensions. By employing a

combination of DEA, SFA, regression models, CBA, and TFP analysis, stakeholders can gain a
holistic understanding of the factors influencing SME performance and implement targeted
strategies to enhance efficiency and competitiveness.
Discussion.
The statistical methods discussed—Data Envelopment Analysis (DEA), Stochastic
Frontier Analysis (SFA), regression models, Cost–Benefit Analysis (CBA), and Total Factor
Productivity (TFP) analysis—offer complementary perspectives on assessing the economic
efficiency of small and medium-sized enterprises (SMEs) and private entrepreneurship. Each
method provides unique insights into different aspects of SME performance, and their combined
application can yield a more comprehensive understanding of efficiency dynamics.
Complementary Strengths and Limitations
Data Envelopment Analysis (DEA):
DEA is a non-parametric method that evaluates the
relative efficiency of decision-making units (DMUs) by constructing a frontier of best practices.
It is particularly useful for benchmarking and identifying efficient firms. However, DEA does
not account for statistical noise, potentially overestimating efficiency scores.
Stochastic Frontier Analysis (SFA):
SFA is a parametric approach that estimates the
production frontier while accounting for random errors and inefficiencies. It allows for the
estimation of efficiency scores and the identification of factors influencing inefficiency.
However, SFA requires a specific functional form and may be sensitive to model specifications.
Regression Models:
Regression analysis examines the relationship between efficiency
and various determinants. It can control for unobserved heterogeneity and temporal dynamics,
providing insights into how factors like firm size, age, and capital structure affect efficiency.
However, regression models may suffer from omitted variable bias if not properly specified.
Cost–Benefit Analysis (CBA):
CBA evaluates the economic feasibility of projects or
investments by comparing the total expected costs against the total expected benefits. It involves
quantifying and monetizing all relevant costs and benefits over the project's lifespan. However,
CBA relies on accurate estimation of costs and benefits, which can be challenging in dynamic
environments.
Total Factor Productivity (TFP) Analysis:
TFP measures the efficiency with which all
inputs are used to produce output. It is calculated as the ratio of aggregate output to a weighted
average of inputs. TFP growth indicates improvements in efficiency and technological progress.
However, TFP analysis requires comprehensive data on inputs and outputs and may not capture
all sources of productivity changes.

6
.
For instance, integrating DEA with clustering algorithms can improve the feasibility of using big
and open data to support decision-making processes in public organizations. Similarly,
combining SFA with data mining techniques can enhance the evaluation of efficiency in
complex environments.
Conclusion. Assessing the economic efficiency of small businesses and private entrepreneurship
is essential for fostering sustainable economic development. The statistical methods reviewed in
this article offer valuable tools for evaluating efficiency, each providing unique insights into
different aspects of SME performance.
By employing these methods, policymakers and entrepreneurs can identify areas for
improvement, allocate resources more effectively, and implement strategies that enhance
competitiveness and growth. A comprehensive approach that integrates multiple assessment
