Production Theory: Accounting for Firm Heterogeneity and Technical Change

The paper presents a new framework to assess firm level heterogeneity and to study the rate and direction of technical change. Building on the analysis of revealed short‐run production functions by Hildenbrand ( 1981 ), we propose the (normalized) volume of the zonotope composed by vectors‐firms as indicator of inter‐firm heterogeneity. Moreover, the angles that the zonotope's main diagonal form with the axes provide a measure of the rates and directions of productivity change. The proposed framework also accounts for n‐inputs and m‐outputs and, crucially, the measures of heterogeneity and technical change do not require many of the standard assumptions from production theory.     

An analytic hierarchy process for ranking operating costs of low cost and full service airlines

This paper develops an application of the analytic hierarchy process to rank the operating cost components of full service and low cost airlines. It takes into account the financial balance sheets and answers to a questionnaire submitted to the managers of selected airlines. The results suggest that the analytic hierarchy process can be appropriately used to obtain the ranking of the costs taking into account different views: financial, management and operative. Rental, office equipment and other supplies costs show the highest importance in the cost ranking, both for full services and low cost airlines. The robustness of the results is tested by Monte Carlo analysis.     

Understanding the size and profitability of firms: The role of a biological factor

In a large sample of entrepreneurs, 2D:4D (second-to-fourth digit) ratio and managerial performance are studied. Entrepreneurs with lower ratio manage larger firms, manage larger firms when acquire control and experience faster average growth. Firms run by high prenatal testosterone entrepreneurs have lower profitability as measured by return on assets and return on sales. Prenatal testosterone is correlated with elicited measures of entrepreneurial skills, like work effort and optimism and the latter are correlated with firm size. This evidence suggests entrepreneurial ability has a biological component and is consistent with models of the size distribution of firms based on entrepreneurial ability.     

Survey measures of risk aversion and prudence

This paper utilizes a thought experiment conducted by the Bank of Italy to estimate absolute and relative risk aversion along with absolute and relative prudence for a broad cross-section of Italian households. Upper and lower bounds are calculated for each parameter, and comparisons are made across socio-demographic groups. Evidence is found of decreasing absolute risk aversion, decreasing absolute prudence, increasing relative risk aversion, and increasing relative prudence.     

Does player specialization predict player actions? Evidence from penalty kicks at FIFA World Cup and UEFA Euro Cup

Penalty kicks are analysed in the literature as ‘real life experiments’ for assessing the use of rational mixed strategies by professional players. However, each penalty kick cannot be considered a repetition of the same event because of the varying background conditions, in particular the heterogeneous ability of different players. Consequently, aggregate statistics over data sets composed of a large number of penalty kicks mediate the behaviour of the players in different games, and the properties of optimal mixed strategies cannot be tested directly because of aggregation bias. In this article, we model the heterogeneous ability of players. We then test the hypothesis that differently talented players randomize over different actions. To achieve this aim, we study a data set that collects penalties kicked during shoot-out series in the last editions of FIFA World Cup and UEFA Euro Cup (1994–2012) where kickers are categorized as specialists and non-specialists. The results support our theoretical predictions.     

Do the Retired Elderly in Europe Decumulate Their Wealth? The Importance of Bequest Motives,Precautionary Saving,Public Pensions,and Homeownership

We use microdata on a large number of European countries from the Survey of Health, Ageing and Retirement in Europe (SHARE) to examine the wealth accumulation (saving) behavior of the retired elderly in Europe. We find that less than half of the retired elderly in Europe are decumulating their wealth and that the average wealth accumulation rate of the retired elderly in Europe is positive though relatively moderate (6.6 percent over a 3-year period). These findings suggest that the Wealth Decumulation Puzzle (the tendency of the retired elderly to not decumulate their wealth or to decumulate their wealth more slowly than expected) applies in the case of Europe. Moreover, our regression results suggest that bequest motives, generous public pension systems, and the reluctance of retired elderly homeowners to sell or borrow against their owner-occupied housing are the primary explanations for the existence of the Wealth Decumulation Puzzle in Europe.     

Does the nano-patent ‘Gold rush’ lead to entrepreneurial-driven growth? Some policy lessons from China and Japan

In this study we compare the nano-patent landscapes of China and Japan in order to assess how their structures (type, fragmentation and concentration of patent ownership) affect the organization of the nanotechnology industry. We also analyze technology policy in order to assess how these interventions support technology transfer and nano-exploitation through university–industry collaboration and technology entrepreneurship. Drawing upon 20,365 patent families related to carbon nanotubes from 1994 to present, we found that two dissimilar technology policies boosting national innovation system emerged: China is more focused on forging an anchor-tenant model, while Japan exhibits a more industry-oriented model through demand-side policy intervention. Implications for firms? strategies and policy makers are discussed.     

Corporate governance and sustainability in water utilities. The effects of decorporatisation in the city of Naples,Italy

The recent economic literature has largely investigated sustainability in the provision of public utilities, highlighting the role of governance models in the determination of economic results. Little attention however has been devoted to the social and environmental dimensions of sustainability. In Italy, a long-lasting debate on governance structures in the water sector has been fuelled by scholars and policymakers for more than 30 years, whereas the first (and unique) experiment involving the return of full public management in water provision is taking place in the city of Naples. The present work analyses this peculiar case study, aiming to assess the effects of a major governance shift that occurred in the early 2010s—that is, decorporatisation—in terms of economic, social and environmental sustainability. We resort to a bundle of qualitative and quantitative techniques to address the research question and our exploratory results suggest that decorporatisation was overall beneficial: Although little changed in terms of economic sustainability, the social and environmental dimensions benefitted from the shift in governance.     

EU quality labels in the Italian olive oil market: How much overlap is there between geographical indication and organic production?

In the early 1990s, the European Union established two main quality schemes: geographical indications (GIs) and organic production (OP). Despite the abundant literature on the EU quality schemes applied to many food categories, including extra virgin olive oil, in most studies, GIs and OP are analysed separately, under the assumption that they are independent. This study aims to prove that synergies exist between GIs and OP labels. We analysed EU labelling on GIs and organic attributes simultaneously using bivariate probit models, and also assessed the level of independence from each other. A survey was administered to Italian consumers to elicit their purchasing behaviour of olive oil. The results found a correlation between the two certifications, highlighting the promising use of both certifications for olive oil products.     

Integrated reporting and cost of capital: The moderating role of cultural dimensions

Since its introduction, integrated reporting (IR) has triggered a rich debate covering several aspects, from the structure and the features of a document to the effects of its publication. Very recently, scholars have examined the negative relationship between IR and the cost of capital for firms, completely missing the opportunity to understand whether this fact is contingent on the cultural context that adopting companies operate in. We fill this gap by resorting to a panel sample of 211 adopters from 31 countries over the period spanning 2009–2017, counting 1,455 observations. Our evidence confirms that adopters, on average, benefit from a 1.4% decrease in the cost of capital. Yet, more importantly, IR effectiveness is exalted in countries with low power distance, strong collectivism values, and high level of masculinity, while uncertainty avoidance, long‐term orientation, and indulgence do not seem to play any moderating role.
