The purpose of this paper is to examine and verify the competitive intelligence tools Alexa and SimilarWeb, which are broadly used for website traffic data estimation. Tested tools belong to the state of the art in this area.

The authors use quantitative approach. Research was conducted on a sample of Czech websites for which there are accurate traffic data values, against which the other data sets (less accurate) provided by Alexa and SimilarWeb will be compared.

The results show that neither tool can accurately determine the ranking of websites on the internet. However, it is possible to approximately determine the significance of a particular website. These results are useful for another research studies which use data from Alexa or SimilarWeb. Moreover, the results show that it is still not possible to accurately estimate website traffic of any website in the world.

The limitation of the research lies in the fact that it was conducted solely in the Czech market.

Significant amount of research studies use data sets provided by Alexa and SimilarWeb. However, none of these research studies focus on the quality of the website traffic data acquired by Alexa or SimilarWeb, nor do any of them refer to other studies that would deal with this issue. Furthermore, authors describe approaches to measuring website traffic and based on the analysis, the possible usability of these methods is discussed.

The impact of competition on innovation has been extensively studied, but with ambiguous findings. We study the impact of import competition on U.S. corporate innovation and present some new perspectives. We conjecture that U.S. firms view import competition from high-wage countries (HWCs) as “neck-and-neck” competition and will respond by intensifying innovation. In contrast, U.S. firms will reduce innovation in response to import competition from low-wage countries (LWCs), because such competition does not always increase the potential benefits from innovation. Our empirical results are supportive. We find that, when confronting HWC import competition, U.S. firms increase R&D spending while intensifying and improving innovation output (file more patents, receive more citations to their patents, and produce more breakthrough patents). Moreover, U.S. firms closest to the technological frontier – largest firms, firms with the largest stocks of knowledge, and most profitable firms – increase and improve their innovation the most in response to HWC competition. These results shed light on the relationship between product market competition and innovation, and point to the origin of import competition as a determinant of innovation decisions made by different U.S. companies.

The authors review the German voluntary turnover literature and examine how it reflects and extends the overall knowledge of employee turnover. First, the authors describe legal, institutional, and cultural influences specific to Germany that may affect voluntary turnover and its relationships with antecedents and outcomes. The authors then explain how research paradigms, which in German turnover research are primarily embedded in sociology and labor economics and to a lesser degree psychology and management, affect the lens by which voluntary turnover is examined. For instance, the variety of research perspectives leads to a variety of research questions, theories, data, and methodological approaches. Using these diverse perspectives, the authors explain how measurement and data quality concerns may hamper the understanding of turnover in cross-country/cross-cultural comparisons. This review further reveals many similarities with US-based turnover research, regarding the theories, methods, and results. The authors also find that turnover levels are, on average, considerably lower in Germany than in Anglo-Saxon labor markets. The authors suggest that the industry structure in Germany, coined by its strong and traditionally organized “Mittelstand” companies, may partly drive these findings. The authors close by identifying several research opportunities, available through advances in technology to improve the matching process, nonstandard work arrangements (such as in the gig economy), and a broader perspective on institutional peculiarities.

It is undoubtedly the case that advertising plays a significant part in modern economic life in most societies and many view it as an essential part of the operation of a free market system. Yet it is also the case that our knowledge of how exactly it works and whether the vast amounts spent on it are justified is still uncertain. Lord Leverhulme, the founder of Lever Brothers, is credited with the famous aphorism — ‘one half of advertising does not work but nobody knows which half’ and that perhaps sums up the situation very well. One thing that is generally accepted is that some protection must be provided both to consumers and trade competitors from false or misleading advertising which can lead to market distortions and economic loss to purchasers. Increasingly controversial, however, is the scope and extent of legal and voluntary controls on advertising. In the advertising industry fears are rising about the volume of both national and EEC proposals to restrict or limit advertising and as we move from the '80s, a decade of conspicuous consumption in which advertising flourished, to the caring '90s where environmental issues are to the fore, the advertising industry faces major challenges. Advertising as a whole is facing severe economic and legal challenges after the massive expansion of the 1980's — it is estimated that there was a 4% fall in real terms in UK advertising expenditure in the first quarter of 1990 and an estimated 5% fall in the second quarter. Clients are becoming more demanding and the cosy cartel arrangement whereby advertising agencies made a 15% standard commission on a client's expenditure has gone — commissions are down to 12%‐13% or being replaced by fixed fees. It has been estimated by the Advertising Association that proposed legal restrictions could lead to a loss of £1 bn in revenue for the industry. Multi‐farious pressure groups are campaigning against drink advertising, cigarette advertising and sexism in adverts. The advertising industry's concerns are reflected in a recent report by the Advertising Association — ‘A Freedom Under Threat — Advertising in the EC’. The report indicates a number of areas where legislative controls have been introduced or are proposed to be introduced over the next few years and expresses the fear that controls may be going too far in limiting freedom of ‘commercial speech’. Martin Boase, chairman of the Advertising Association writes in his introduction to the report:

The purpose of this study is to analyze how occupational licensing costs within a state affect the performance of self-employed firms, as measured through annual sales.

This study utilizes an empirical approach to determine if there are additional effects on the annual sales for firms that are self-employed in high-cost states that are not explained through the individual estimations. Since the choice of self-employment is plausibly nonrandom, this study also uses a propensity score matching method to develop a matched subsample of self-employed and employee-maintaining firms. This selection methodology ensures that the set of self-employed and employee-maintaining firm observations are similar in all measurable attributes besides their regulatory environment and firm structure. Using this representative subsample, the empirical framework is repeated to reevaluate the effects of high occupational licensing fees on the sales of self-employed firms.

In both the unmatched and matched samples, there are significant, large, negative interactions representing a reduction in annual sales per employee within self-employed firms relative to employee-maintaining firms when located in states with above-average occupational licensing costs. The results using the matched subsamples are noticeably smaller in magnitude, which indicates that future policy assessments would benefit from ensuring that the sample pool, when dealing with self-employment, is limited only to firms under a common convex hull in order to not skew the size of results.

This study contributes new understanding of the financial relationship of self-employed firms and occupational licensing costs using firm-level observations of sales and firm structure. This has important policy implications for the development and evaluation of occupational licensing policies when considering effects on the self-employed.

Academic dialogue related to ‘organizational performance’ in strategic management has primarily centred around the industrial organization theory (IO) and resource-based view (RBV). Both perspectives, though conceptually dialectic, have served as primary competing theories governing research studies in the domain of strategic management. However, the confluence of these theoretical perspectives has not been adequately explored to advance a shared view of competitive advantage. This study aims to explore the likelihood of embedded commonalities between RBV and IO.

A bibliometric analysis was conducted to visualize the intellectual map of studies and knowledge development encompassing these theories. This was followed by a comprehensive literature review to understand how the business environment (BE) and organizational capabilities have contributed towards attaining competitive advantage.

This study established that connecting the intellectual boundaries of these theoretical perspectives would facilitate better comprehension of the processes and outcomes in organizations. Integrating the knowledge emerging out of this methodological blend, a convergence framework connecting the intellectual boundaries of both theories was presented.

The framework that emerged from this study would help in better understanding of organizational behaviour from a dual theoretical lens. It would also motivate future studies to consider RBV and IO as complementary theories rather than the current narrative of competing theories.

This study added to the efforts to achieve equilibrium between the BE and internal capabilities of organizations so as to maximize positive social externalities.

This study contributed to the limited attempts to leverage shared knowledge from a dual perspective using a comprehensive literature review in sequential combination with bibliometric analysis.

The purpose of this paper is to show that entrepreneurship can be fruitfully analyzed by positing that entrepreneurs are searching for rates of return exceeding the risk-adjusted market rate of return, i.e., they try to create or discover economic rents.

A conceptual paper trying to bridge the gap between neoclassical economics and the entrepreneurship field by seeing entrepreneurship as the search for and creation of (entrepreneurial) rents.

In the short to medium term the search for and creation of entrepreneurial rents give rise to supernormal profits if successful. In the longer term these rents are dissipated and accrue to society at large as cheaper and better products. Entrepreneurial rents are crucial for bringing about the innovation and continuous structural change required to generate economic growth.

The search for entrepreneurial rents is crucial for economic development. Without the possibility to earn entrepreneurial rents, no entrepreneur would be willing to exercise entrepreneurship and exploit entrepreneurial opportunities. Successful entrepreneurship attracts imitating firms that push back profits to normal levels and the benefits of the innovation will be diffused to consumers.

Understanding the role of entrepreneurship and its compensation is crucial for analyses of potential policy measures. High ex post compensation for successful entrepreneurship cannot be taxed harshly without affecting entrepreneurs’ willingness to supply effort.

The entrepreneurial function and its compensation are often neglected in neoclassical economics. This is a major shortcoming, as the presence of and search for entrepreneurial rents are necessary for bringing about the innovation and structural change that result in economic growth.

As an economic development strategy, entrepreneurship policies should target innovative activities – those which Schumpeter described as leading to new goods, production methods, markets, input sources, or new industries. However, popular entrepreneurship proxies, such as firm births (<500 employees) and sole proprietorships, capture multiple types of entrepreneurship which may have conflicting qualities. To address the need for more accurate measures of Schumpeterian activity, indices are constructed to specifically measure the relative amount of Schumpeterian activity among US states. The paper aims to discuss these issues.

Four composite indices of Schumpeterian activity are constructed using different methods to combine variables related to innovative activity into single indicator, since there is uncertainty about the weighting of dimensions: principal component analysis (PCA), factor analysis (FA), data envelopment analysis and equal weights. Robustness checks were used to compare state rankings across indices. These indices were also compared to common entrepreneurship proxies and real GDP to demonstrate and justify their measurement of Schumpeterian activity.

The results show that the Schumpeterian Activity Indices (SAIs) similarly rank states and measure phenomena different from the common proxies of entrepreneurship. Furthermore, these indices better predict GDP than the common proxies. Lastly, state rankings based upon the SAIs support previous research suggesting that innovation and agglomeration economies are interrelated.

The paper demonstrates a methodology for constructing a measure of innovative activity, which is necessary to develop and evaluate entrepreneurship policy for economic development.
