Scope:

• This paper applies the framework of ecological network analysis to input–output data. 
• Captures resilient economic structures between self-sufficiency (redundancy) and extreme specialization (efficiency). 
• Calculates the structural resilience of 69 countries.

Contribution, novelty:

• Economies are more redundant than ecological systems and moved towards more efficient structures over time. 
• Economically more open economies on the export side are more efficient and less structurally redundant, reflecting that specialization and integration into global supply chains go hand in hand. 
• Significant empirical relationship is found between structural resilience and changes in unemployment.

Practical relevance:

• Measuring the structural resilience of national production networks helps capture the robustness of economic systems and provides a tool to design more resilient production systems.

Scope:

• This study challenges the assumption that well-balanced and bottleneck-free entrepreneurial ecosystems (EEs) are the sole drivers of high regional economic performance.

Contribution, novelty:

• We find that high regional economic performance does not universally necessitate the presence of every ecosystem component. • Rather, contextual nuances across European macro-regions show that both balanced and unbalanced ecosystems can lead to significant economic success, emphasizing the importance of recognizing uniqueness.

Practical relevance:

• Policy efforts should focus on acknowledging and leveraging the uniqueness of regional ecosystems rather than striving for a one-size-fits-all approach to enhance economic performance.

Scope:

• The proposal of the European Super League and the 2024/25 reform of the UEFA Champions League are both major events in European club football.
• This study compares the competitive balance (CB) of these new tournament formats with the previous Champions League format.

Contribution, novelty:

• Short-, mid- and long-term CB are quantified by measuring the average uncertainty of match outcomes, the ratio of stakeless matches, and the recurrence ratio of teams in knockout rounds.
• A simulation method is applied using the teams, their seeding, and Elo ratings in the 2020/21 and 2021/22 Champions League seasons.
• The 2024/25 reform improves CB, especially in match uncertainty and the occurrence of stakeless matches. The Star League of the European Super League concept of December 2023 is superior concerning average match uncertainty.

Practical relevance:

• According to our simulation results, the structural reform of the CL from the 2024/25 season is expected to bring a competition with better short- and mid-term CB in its initial stage.
• The ESL would be a move towards an American-type closed league with a far stronger entry barrier to the Star League than the CL.

Scope:

• Some corporate strategies extend beyond conventional sustainable approaches by embracing the fundamental operating principles of ecosystems.
• In this context, resilience—a natural risk management strategy—is incorporated into the design of a manufacturing company, considering all types of material flows, including solid, liquid, gaseous, and thermal.

Contribution, novelty:

• Results indicate that merely achieving zero waste emissions does not ensure sufficient resilience, a core requirement of ecosystems and a fundamental principle of the blue economy.
• Furthermore, it is found that a production system with a flexible product portfolio can adapt into a more ecologically resilient system, despite technological constraints.

Practical relevance:

• A key message is that production processes should follow ecological systems' risk management methods to provide resilience.
• This can be achieved by fostering adaptable production systems with flexible product portfolios, enabling companies to adjust production in response to technological and market changes.

Authors:

Zsolt Darvas, Zoltán Schepp

Scope:

•The study shows that in a popular model of exchange rate determination, the unobserved expected future exchange rate can be substituted with the observed forward exchange rate.  
•This allows the derivation of a new error-correction forecasting model, which approximates the gap between the fundamental equilibrium exchange rate and the actual exchange rate with the long-maturity forward exchange rate. 

Contribution, novelty:

• The unobserved expected future exchange rate can be substituted out with the observed synthetic forward exchange rate in the general class of rational expectations present value exchange rate models. 
• With a novel combination of the exchange rate model of Engel and West (2005) and the error-correction forecasting equation of Mark (1995) and Chinn and Meese (1995), we show that the forward exchange rate can be taken as a proxy for the difference between the fundamental equilibrium exchange rate and the current exchange rate when the maturity of the forward rate is long. 
•Unprecedented out-of-sample forecasting results are reported, more leading to forecasts more accurate than the random walk for many years and all major currencies.

Practical relevance:

• The forecasting results exhibit a marked improvement over past works with a novel model that is based on a novel theoretical justification. 
•In contrast to various overly complicated models in the literature, the suggested model is extremely simple, linear, easy to replicate, and the data used are available in real time and not subject to revisions.

Scope:

•The study analyzes the determinants of wage inequality and its fluctuations in six Central-Eastern European nations using European Union Statistics on Income and Living Conditions microdata from 2010 to 2019. 
•In addition to providing a detailed description of inequality trends in these countries, the demographic and micro-level determinants alongside the minimum wage changes is examined. 
•These effects are estimated using RIF regression and RIF decompositions for various inequality measures. 

Contribution, novelty:

• The changes in wage inequality in the sample countries were driven mainly by wage structure effects regardless of the increase or decrease in wage inequality. 
• Changes in the returns to education and returns to permanent employment contracts are crucial in explaining decreased wage inequality. 
• The changes in the minimum wage explain most of the unknown factors in Bulgaria, and the spillover effects of the minimum wage may explain most of the unknown factors in Hungary. 

Practical relevance:

• The results can support the skill-biased technological change hypothesis in the case of Slovakia, Romania, Czechia, and Bulgaria.

Rappai, Gábor, Fűrész, Diána Ivett

Scope:

•Through the data of the last 18 seasons (2004/05–2021/22) and 576 games, this study examines whether the teams from a more balanced domestic league can achieve more unexpected results in the Champions League group stage.

Contribution, novelty:

• The study contributes to previous literature by applying the market value-based surprise index. 
• The results of panel logistic regression models suggest that a domestic league's lower CB in a given season can support teams to overperform in the international field in the same season. 

Practical relevance:

• The results call for a revision of several factors by the governing body of the UEFA: determining the number of clubs from the same league, the revenue distribution system, or the amount of prize money.

Authors:

Dániel Hegedűs, Dóra Longauer

Scope:

• The paper deals with a version of Economic Order Quantity (EOQ) and Economic Production Quantity (EPQ) models, consideering the reusability of raw materials and components in multiple product generations.
• Presents available solutions for managing end-of-life products and aims to present a cost minimization EOQ/EPQ model.
• Examines optimal inventory strategy when products returned from consumers are not remanufactured but disassembled and the extracted components are used in the production of the next product generation.

Contribution, novelty:

• The results provide the optimal strategy for the number of cycles of extracted and new components during the production and identifies the variables affecting this optimal strategy.
• Results show that the company's production rate and set-up costs influence the company's optimal strategy, while the inventory cost has a smaller influence on the optimal strategy.

Practical relevance:

• The options presented can help companies decide what re-use options are available to them.
• With the help of the method, companies can determine the optimal re-use strategy based on company characteristics and product parameters.
• As a result of the company reusing previously manufactured components, the amount of generated waste is reduced, and the extraction of new raw materials and energy consumption are also reduced.

Authors:

Zsuzsanna Hauck, Boualem Rabta, Gerald Reiner

Scope:

• The paper proposes an optimization model to analyze the impact of quality decisions, buyer dominance, and coordination in a two-stage supply chain.
• The investigation centers on the seller–buyer relationship, exploring coordinated and non-coordinated buyer-dominated contracts. Screening time acts as a decision variable affecting the quality level of the batch and influences costs and consumer demand.

Contribution, novelty:

• Analytical solutions are provided and supported with numerical examples to illustrate the consequences of quality decisions for overall profitability of the supply chain.
• Under buyer dominance, the buyer can dictate wholesale prices and quality standards while the seller bears the burden of screening costs.
• Achieving coordination and implementing optimal screening practices may create a win-win situation for supply chain partners.

Practical relevance:

• Coordination in supply chains can increase overall supply chain profitability, decrease retail prices, and improve quality levels, ultimately enhancing consumer satisfaction.

Scope:

• This paper explores the issue of platformization in three developed and high-income countries in the European Union: Germany, France and Austria.
• The framework and empirical measurement of the Digital Platform Economy (DPE) Index are used to analyze the state of Digital Entrepreneurial Ecosystem (DEE) in these three countries, identify the most prominent weaknesses that could be barriers, and propose policy recommendations to overcome these barriers and promote the development of DEE.

Contribution, novelty:

• The results of the three-step investigation present the current state of DEE in each country and find that similar constraining elements in the Digital Multi-Sided Platforms of the three countries have the most potential to systemically disrupt the DEE balance.

Practical relevance:

• Tailor-made policies with a holistic approach are recommended to address these constraining elements and target overall DEE growth.

Scope:

• This study provides a product network-based analysis of the impact of the Russia–Ukraine war on the economy of third countries.
• The method also provides a decomposition of exposures on a country-by-country basis.

Contribution, novelty:

• Recent studies based on input-output data already revealed several economic consequences of the conflict, the approach in this study allows for more detail regarding geographical coverage and heterogeneity of the affected products.beneficial as they can contribute to increased productivity at other stages.
• We apply a comprehensive indicator of exposure and measure the dependence of third countries on products imported from Ukraine or Russia.

Practical relevance:

• The study also analyses the relationship between trade exposure and the extent to which countries were willing to support Ukraine. Results show that it is not exposure itself, but the decrease of exposure over time which correlates with military support.

Ágnes Neulinger, Gabriella Kiss, Tamás Veress

Scope:

• This study demonstrates the importance of communities as potential vehicles of social change.
• Relying on in-depth interviews, the meaning of community and the role of sustainability in the operation of these communities is examined.
• The analysis focuses on an understanding of communities that goes beyond the differentiation of individual (micro) and social (macro) levels.

Contribution, novelty:

• The findings indicate blurring boundaries in the green agenda. The role of new environmental organizations seems to be as important as the role of old, traditional organizations in Budapest.
• There has been an observable shift in the case of traditional organizations to broaden their horizons and work with complex issues related to social and environmental justice. They are also moving beyond the strict positioning of green organizations and positioning themselves under alternative terms.

Practical relevance:

• The labels “green” and “sustainable” are no longer the exclusive markers for communities with awareness of environmental issues in Budapest.

Scope:

• The paper investigates the situational and engagement-related work difficulties associated with the everyday world of Community Supported Agriculture (CSA) farmers.
• The proposed analysis of composite indicators allows the computation of endogenous (country-specific) weights that can be used for developing more informed policy making.

Contribution, novelty:

• Newer producer-consumer connections require both time and experience and involve extra effort or skills, but farmers often lack these abilities.
• The results show how perceptions of work processes relate to the general framework of CSA, which necessitates a distinct strategy for farm management.

Practical relevance:

• Specific training and development programs could help farmers to improve the skills that would enable them to better demonstrate a sustainable farming role, and work scheduling or decision-making autonomy.

Scope:

• This study evaluates the quality of the digital platform economy at the global scale by employing a network model rooted in nonparametric linear techniques (data envelopment analysis) on a sample of 116 countries for 2019.

Contribution, novelty:

• The core findings indicate that the configuration of countries’ platform economy is very heterogeneous.
• This suggests that an informed, tailor-made approach to policy might produce more effective outcomes.

Practical relevance:

• Policies aimed at enhancing the digital platform economy should emerge from the analysis of its main factors if the development of a strategy seeking qualitative improvements in the system is the desired goal.

Scope:

• The study introduces an application of an agent-based model that is appropriate for modeling the dynamics of network formation based on different proximity dimensions.
• With the help of unique survey data about the Hungarian gazelles, we have conducted our analysis on a broad range of formal and informal cooperation, which allows a more in-depth understanding of collaboration in innovation.

Contribution, novelty:

• Successful entrepreneurship policy, that induces spin-offs in a given sector, could significantly increase the number of relationships between the organizations.
• Findings show that spin-off formation is conducive not only for the sector concerned but it has a spillover effect on other industries.

Practical relevance:

• Policies targeting network formation can be better designed with the help of the model.
• Larger economic impact models can integrate the proposed method to simulate economic effects of different network-related interventions.

Scope:

• Athletes born late in the selection year are disadvantaged compared to the relatively older in youth age groups. This leads to an overrepresentation of the early-born in professional teams, which is called the relative age effect (RAE).
• This paper aims to estimate the partial RAE on the market value of top-level European football players with a new methodology.

Contribution, novelty:

• Unlike prior studies, we found an extremely strong straight RAE in elite European football, especially for younger players.
• Using our methodology, we interpret RAE as a partial effect, which indicates that an earlier birth date within the calendar year results in a higher market value.

Practical relevance:

• Our results imply discrimination based on birth date in several countries, which needs to be reduced by better regulation of youth competitions.
• Our findings have implications for coaches and managers on how to account for relative age when training, transferring, and selecting players.

Scope:

• A manufacturing process with an early stage of quality control is considered.
• Impact of screening time on both screening costs and defect detection rate via different linear and nonlinear functions are investigated.

Contribution, novelty:

• New EPQ model with two stages of quality control: early-stage screening after the most critical operation and final screening.
• Numerical examples illustrate the impact of various parameters.

Practical relevance:

• Devoting more time to the initial screening increases the inspection cost but allows a greater proportion of defects to be detected early, and saving cost of subsequent stages.
• Managerial insights are dealing with highly relevant trade-offs.
• Results highlight the importance of careful estimation of the defect rate.

Scope:

• In this study, 455 US and European manufacturing and service firm's data are examined from the period 2010–2019.
• The purpose of the investigation was to determine if there are any positive impacts of a golden ratio-based capital structure on financial performance and market acceptance.

Contribution, novelty:

• Significant positive relationship is found between the deviation from the golden ratio-based capital structure and the deviations of firms' revenue, income, stock price and market value data from their historical maximum.
• This relationship is more obvious in the United States than in Europe, and stronger for service firms than for manufacturing companies.

Practical relevance:

• The golden ratio-based capital structure may be an efficient tool for firms to boost their performance and market acceptance.

Scope:

• The study employs the ‘benefit of the doubt’ approach to evaluate the entrepreneurial ecosystem of 71 countries for the period 2016.
• The proposed analysis of composite indicators allows the computation of endogenous (country-specific) weights that can be used for developing more informed policy making.

Contribution, novelty:

• Results show that countries prioritize different aspects of their national system of entrepreneurship, confirming that tailor-made policy is necessary if the objective is to optimize the resources deployed to enhance the countries’ entrepreneurial ecosystem.
• There is a significant positive correlation between quality improvements in the entrepreneurial ecosystem and venture capital investments.

Practical relevance:

• Significant improvements in the quality of the entrepreneurial ecosystem can be realized by targeting the policy priorities of the local entrepreneurship system identified by the ‘benefit of the doubt’ weights.

Scope:

• This study analyzes political clientelism and the softness of budget constraint for local governments from the persepctive of both local and central decision-makers

Contribution, novelty:

• The author conduct an analysis regarding the Hungarian local government system between 2006 and 2018 to capture the political patterns in local fiscal policy and central granting policy
• The fiscal discipline was lower at aligned local governments
• Local governments in opposition were underfinanced
• Favoured municipalities enjoyed more funds and could deliver more projects to their citizens
• The unaligned local governments struggled to establish a fair distribution of the burdens between beneficiary generations

Practical relevance:

• The study emphasizes that fair distribution of burdens is key to exploit the benefits of fiscal decentralization.
• The study provides information to policy-makers about the nature of budget constraint for local governments
• Policy-makers may get insight about the importance of raising own revenues and the role of central grants in municipal financing.

Scope:

• The study examines a cross-country analysis to measure the systemic operation of national economies through the importance of domestic sectors as a supplier
• Using panel-econometric techniques, the study points out the role of the openness and structural asymmetry in shaping this strength

Contribution, novelty:

• The structure of the domestic production network is different across countries in terms of sectors’ centrality and the intensity of the linkages between domestic sectors
• The estimates reveal that openness has a negative, while asymmetry has a positive effect on this index, but other country specific characteristics also play a role in shaping the systemic operation of nationaleconomies

Practical relevance:

• The level of systemic operation can be a useful signal of how resilient an economy is to emerging global shocks such as a pandemic, natural disasters or wars

Scope:

• The study examines the effects of subclinical ADHD symptomatology on the subjective quality-of-life outcomes in employment and entrepreneurship.

Contribution, novelty:

• The results indicate that subclinical ADHD impairs only entrepreneurs’ subjective income and harms entrepreneurs’ health perception to a larger extent than that of employees. Yet, the negative effects of ADHD symptomatology on life satisfaction are rather felt among employees.

Practical relevance:

• We argue that these results reflect a relatively good fit between entrepreneurship and subclinical ADHD symptomatology on the needs-supplies dimension but not on the demands-abilities dimension.

Scope:

• The speed of implementing productivity knowledge increase is a key component of competitiveness and for the case when the implementation is instantaneous, an optimal control model is developed.

Contribution, novelty:

• A closed form solution is provided to determine the optimal production level.

Practical relevance:

• If the implmentation of gained knowledge increases is instantenous, then the production rate is constant over time for a zero discount rate and is increasing for positive discount rate.
• If implementation happens step by step, production dynamics will be decreasing in case of zero discount rate and for a positive discount rate,the dynamics can be decreasing and increasing as well.

Scope:

• This study examines the link between entrepreneurs’ beliefs in their entrepreneurial skills and the actual or expected growth of their venture

Contribution, novelty:

• The outcomes of the analyses reinforce that the incongruent results on the relationship between perceived entrepreneurial skills and expected and realized growth may be due to the variations in the form of entrepreneurial overconfidence, the actual and perceived skill relationship and the strengthening effect of the more realistic entrepreneurial expectations

Practical relevance:

• Policy makers could found programs that support new venture owners to appropriately evaluate their skills and the expected outcome of their business

Zsuzsanna Hauck, Boualem Rabta, Gerald Reiner

Scope:

• The study examines an Economic Order Quantity (EOQ) model with imperfect quality items where both the cost and the defect detection rate depend on the time devoted to screening.
• Screening time is decision variable jointly with the order quantity.

Contribution, novelty:

• Screening-time dependent screening cost and defect detection functions are defined.
• Nonlinear forms lead to nonconvexities in the total cost function consisting of multiple cost components, e.g. inspection cost, penalty costs, etc. 

Practical relevance:

• Reducing return rates and improving customer satisfaction can be achieved by adjusting the operational parameters, without a significant increase in system cost or new investments.
• Lower screening costs motivate longer screening times, the effectiveness of this operation is only obtained in combination with the reliability of the defect detection method.

Scope:

• This paper introduces how enterpreneurship (the REDI) and knowledge networks (the ENQ index) are implemented in the GMR-Europe (geographic, macro and regional) model.

Contribution, novelty:

• The simulations highlight that smart specialization policy targeting the development of enterpreneurship and knowledge networks is not equally successful in all regions.
• The impact of policies depends on several interrelated factors (level of enterpreneurship in the region, the embedness of the region in the interregional knowledge networks, the magnitude of policy shocks, the size of R&D and human capital, etc.).

Practical relevance:

• The model could helpfully contribute to the design of a Smart Specialisation Strategy.

Scope:

• This paper demonstrates how the Regional Entrepreneurship and Development Index (REDI) can be used to optimize local entrepreneurial discovery processes, in a manner which can support smart specialization strategies (S3)

Contribution, novelty:

• While S3 industry prioritization is based on the identification of local strengths, regional improvement can be achieved by improving the weakest features of the local entrepreneurial ecosystem

Practical relevance:

• Without optimizing the entrepreneurial ecosystem, the industry prioritization alone may not be successful because of the inability of the ecosystem to be able to nurture high growth potential ventures

Scope:

• The study analyses the options which are not in-the-money due to higher potential gains for a smaller upfront cost

Contribution, novelty:

• The study shows that stock returns increase with AveMoney (a measure of stock-level dollar volume-weighted average moneyness ), suggesting informed options traders prefer to use options that offer higher leverage
• The results are strongest when AveMoney is calculated using call options only, probably because puts are often used for hedging while calls are more often used for speculating on future stock price movements

Practical relevance:

• The study demonstrates that relative trading activity in options of different moneyness levels can signal the direction of future stock returns.

Scope:

• This paper evaluates how country-level entrepreneurship—measured via the national system of entrepreneurship—triggers total factor productivity (TFP) by increasing the effects of Kirznerian and Schumpeterian entrepreneurship

Contribution, novelty:

• The authors employ non-parametric techniques to build a world technology frontier and compute TFP estimates
• The results of the common factor models reveal that the national system of entrepreneurship is a relevant conduit of TFP and that this effect is heterogeneous across countries

Practical relevance:

• The policy-makers need to turn their attention to the development of an appropriate national system of entrepreneurship; and prioritize policies that promote the ‘interconnector’ role of the national systems of entrepreneurship

Scope:

• This study analyzes conceptually and in an empirical counterpart the relationship between economic growth, factor inputs, institutions, and entrepreneurship.

Contribution, novelty:

• The paper investigates whether entrepreneurship and institutions, in combination in an ecosystem, can be viewed as a “missing link” in an aggregate production function analysis of cross-country differences in economic growth.
• The paper builds on the concept of National Systems of Entrepreneurship (NSE) as resource allocation systems that combine institutions and human agency into an interdependent system of complementarities.

Practical relevance:

• The study explores the empirical relevance of these ideas using data from a representative global survey and institutional sources for 46 countries over the period 2002–2011.  
• The empirical analysis finds support for the role of the entrepreneurial ecosystem in economic growth.

Scope:

• The purpose of this paper is to  investigate whether Russia is a normal country in terms of entrepreneurship by comparing Russia with other post-socialist and similarly developed countries.

Contribution, novelty:

• In this study the authors use the Global Entrepreneurship Index (GEI) methodology to analyze Russia’s quality-related individual as well as institutional features from a system perspective in a single model.
• The single-model framework reveals that individual factors are even greater obstacles to entrepreneurship development in Russia than the institutional factors that most studies focus on.

Practical relevance:

• The results show that conditions supporting entrepreneurship in Russia lag seriously behind other post-socialist countries.
• Russia’s individual scores are even lower than the institutional ones. 
• Hence, improving the hostile environment alone would not be sufficient for entrepreneurship development.

Scope:

• This study surveys the most important modeling challenges raised by the two modern economic development approaches: the space-neutral and the place-based approaches.

Contribution, novelty:

• To illustrate how economic models can respond to
these challenges the author briefly introduces the GMR-Europe model.
• It is found that promoting research excellence in leading agglomerations combined with human capital development in the rest of the regions in Europe could result in a sustained positive GDP impact of EU Framework Programs at the aggregate EU level.
• It is also important to emphasize that the aggregate impact masks marked regional differences.

Practical relevance:

• This paper suggests macroeconomic models that integrate geography could usefully help policymakers in their choice among different complex geography-instrument mixes.

Scope:

• This paper is a guide for both researchers and practitioners in risk capital allocation. 
• If a financial unit consists of subunits, then the risk of the main unit should be allocated to the subunits using a risk capital allocation method in a fair way.

Contribution, novelty:

• In this study the authors analyze seven risk capital allocation methods applying coherent measures of risk. 
• The study proves how the seven methods perform in terms of ten fairness properties. 
• The simulation of Core Compatibility in 24 treatments is up to nine subunits.

Practical relevance:

• The conclusion of the results show that some of the ten properties should be given up in practice. 
• The paper can serve as a useful guide for both practitioners and researchers.

Scope:

•The paper developed a model capable of simulating the electricity system of Hungary. 
•It was used to simulate three possible scenarios for the electric power system for 2030.

Contribution, novelty:

•The results of the simulations show that developing the changes proposed in the scenario of the authors,  Hungary would operate an electric power system which is diversified with respect to fuel input, has double the renewable energy share than the business as usual scenarios, and uses 38% domestic sources to cover its electricity demand, compared to 15.8% for the business as usual scenarios. 
•Also, its emission intensity would be 35% less than the
business as usual scenario where the current centralized, fossil fuel
based production strategy would continue.

Practical relevance:

• This much more secure and environment friendly electric power system would not be unaffordable, as it was shown that the development and the operation of such a system could be 3.4%-32.3% more expensive to build and operate. 
•This costs could be outweighed by the tremendous advantages in energy security and environmental impact.

Scope:

• This study developes a new lot sizing model in JIT environment. 
• The characteristics of the total cost is analyzed as a function of demand, and suggests a way to determine the optimum demand volume in the contracts.

Contribution, novelty:

• As the occurrence of problems (deviations and variability) is natural, the authors consider both the output of the assembly line and the frequency of violating the Jidoka principle (cars with quality problem are tagged and go through the assembly line arriving at the clinic area and waiting for repairing) random variables.
• These two random factors result in new lot sizing rules and modify the traditional formulae.  
• The results prove that the sales volume minimizing this function decreases when backlogging costs increase.

Practical relevance:

• The analysis of the case emphasizes the importance of the inclusion of the clinic area into the discussion not only because in JIT systems clinic area exists, but the last two propositions indicate that core problems may behave differently.

Scope:

•This paper tests the efficiency hypothesis of the knowledge spillover theory of entrepreneurship.

Contribution, novelty:

• Results support the efficiency hypothesis of knowledge spillover entrepreneurship. 
• The paper shows that innovation-driven economies make a more efficient use of their resources, and that the accumulation of market potential by existing incumbent businesses explains country-level inefficiency.
• Regardless of the stage of development, knowledge formation is a response to market opportunities and a healthy national system of entrepreneurship is associated with knowledge spillovers that are a prerequisite for higher levels of efficiency. 

Practical relevance:

• Public policies promoting economic growth should consider national systems of entrepreneurship as a critical priority, so that entrepreneurs can effectively allocate resources in the economy.
