Testing for Hysteresis in Unemployment in OECD Countries: New Evidence using Stationarity Panel Tests with Breaks*

This paper tests hysteresis effects in unemployment using panel data for 19 Organization for Economic Co‐operation and Development (OECD) countries covering the period 1956–2001. The tests exploit the cross‐sectional variations of the series, and additionally, allow for a different number of endogenous breakpoints in the unemployment series. The critical values are simulated based on our specific panel sizes and time periods. The findings stress the importance of accounting for exogenous shocks in the series and support the natural‐rate hypothesis of unemployment for the majority of the countries analysed.     

Audit firm tenure and audit quality: A cross‐European study

Directive 2014/56/EU and Regulation (EU) No. 537/2014, which came into effect in June 2016, introduced the mandatory rotation of audit firms after a maximum period of 10 years with the same client. We conduct a cross‐European study with the aim of assessing whether long audit firm tenures are associated with lower levels of audit quality. The sample for the study is based on the constituents of the Standard & Poor's Europe 350 index for the years between 2009 and 2016, and we utilize three different sets of proxies for audit quality: discretionary accruals, differences between reported earnings and earnings benchmarks, and accounting restatements. The main result of the study finds that companies with more than 10 years of tenure with their auditors do not have a lower audit quality than other firms. In fact, this study provides some evidence of a higher audit quality for these firms. The results are robust to various checks. Therefore, if there does not seem to be a problem of a lack of audit quality associated with long audit firm tenures, the necessity of establishing a maximum tenure, as the new European regulation does, may be questioned.     

Green practices in restaurants: Impact on firm performance

Although some researchers have recently studied green practices in restaurants, scant previous research has analyzed the impact of these practices on overall performance in this field. Moreover, these studies have generally focused on mega-sized restaurants in the United States. The primary objective of this study is therefore to examine the motivations for the adoption of green practices in restaurants in Spain and the impact of this adoption on firm performance. The results are based on a survey completed by 374 small restaurant managers. Structural equation modeling was used to analyze links between the studied dimensions. The findings indicate that green practices have a strong positive direct influence on operational performance and competitiveness in Spanish restaurants and that they indirectly influence overall firm performance. Therefore, the results of this paper suggest that being proactive about environmental issues can provide restaurants with a great number of benefits that improve firm competitiveness and performance.     

The relation between segment disclosure and earnings quality

We investigate the relation between segment disclosure and earnings quality. Using a US sample for the period 2001–2006, we find a positive relation between earnings quality and the quantity of segment disclosures. We use lead-lag tests to examine the flow of causality, and our results show that current segment disclosure is positively related to prior levels of earnings quality, while current earnings quality scores are not related to prior levels of segment disclosure. Thus, the causality flows from earnings quality to segment disclosure. Our results hold for both business and geographic segment disclosure.     

Synergies Among Advertising Channels: An Efficiency Analysis

The following article measures and compares efficiency of five advertising channels (TV, press, radio, online, and outdoor) with the help of DEA (Data Envelopment Analysis) methodology and looks for synergy effects among them. The synergy effect was indeed found in certain combinations of media while internet was found to be second least effective advertising channel, contrary to the expected.     

Searching for New Forms of Legitimacy Through Corporate Responsibility Rhetoric

This article looks into the process of searching for new forms of legitimacy among firms through corporate discourse. Through the analysis of annual sustainability reports, we have determined the existence of three types of rhetoric: (1) strategic (embedded in the scientific-economic paradigm); (2) institutional (based on the fundamental constructs of Corporate Social Responsibility theories); and (3) dialectic (which aims at improving the discursive quality between the corporations and their stakeholders). Each one of these refers to a different form of legitimacy and is based on distinct theories of the firm analyzed in this article. We claim that dialectic rhetoric seems to signal a new understanding of the firm’s role in society and a search for moral legitimation. However, this new form of rhetoric is still fairly uncommon although its use is growing. Combining theory and business examples, this article may help managers and researchers in the conceptualization of how firms make sense of their role in society and what forms of differentiation they strive for through their rhetoric strategies.     

Firm Size and Geographical Aggregation: An Empirical Appraisal in Industrial Location

This paper assesses empirically the importance of size discrimination and disaggregate data for deciding where to locate a start-up concern. We compare three econometric specifications using Catalan data: a multinomial logit with 4 and 41 alternatives (provinces and comarques, respectively) in which firm size is the main covariate; a conditional logit with 4 and 41 alternatives including attributes of the sites as well as size-site interactions; and a Poisson model on the comarques and the full spatial choice set (942 municipalities) with site-specific variables. Our results suggest that if these two issues are ignored, conclusions may be misleading. We provide evidence that large and small firms behave differently and conclude that Catalan firms tend to choose between comarques rather than between municipalities. Moreover, labour-intensive firms seem more likely to be located in the city of Barcelona.     

Sustainability in small tourist businesses: the link between initiatives and performance

This study explores the combined effects of adopting sustainable practices on small tourism companies’ performance. The existing literature provides insufficient data on sustainable behaviour because most studies on environmental practices focus on larger companies in the tourism sector, and a gap exists in social practices. This study is based on a survey of 374 restaurant managers. It uses structural equation modelling to study direct links between three dimensions – quality, environmental practices and social practices – and financial performance and market success factors. Significant differences with earlier studies are found. This study suggests that proactive sustainable practices can benefit small service companies by improving competitiveness even in difficult times. Practical implications are discussed in relation to sustainable practices.     

The use of financial accounting information and firm performance: an empirical quantification for farms

Many firms that do not have a formal obligation to prepare financial statements do not produce any accounting information voluntarily, either. However, as accounting information is generally believed to be useful for decision making, the reasons for this behaviour are unclear. In this paper we try to shed some light on this question and provide empirical evidence on the relationship between the use of financial reports and financial performance. In particular, we collected data on the use a sample of Catalan farmers made of the financial reports that were provided to them free by the European Farm Accountancy Data Network. We matched these observations with different financial indicators and found that the financial performance of farmers using the reports for decision-making purposes was significantly better than those who did not use the reports. These results suggest that financial reports can indeed be of use to managers. However, firms will only benefit if the expected gain in performance is sufficiently large to offset the costs of obtaining the reports. Although for the average farm the performance gain was probably sufficiently large to make accounting worthwhile, this was not the case for the smallest farms in our sample.
