IFRS Taxonomy and financial reporting practices: The case of Italian listed companies

XBRL taxonomies have a crucial role in digital financial reporting. On the one hand, they provide a unique set of computer-readable tags to allow the interchange of interactive information. On the other hand, a systematic, agreed-upon convention for naming each taxonomy tag is needed. In this context, the IFRS Foundation is playing a relevant role in developing well-structured taxonomies, which could simultaneously favor both the interoperability and the homogenization of the firms' financial information at the global level. Due to its importance, XBRL is being applied in many countries, but according to different implementation schemas.In this study, we attempt to verify if the IFRS Taxonomy released by the IFRS Foundation adequately reflects the reporting practices of the Italian listed companies for which XBRL is not yet required. The results reveal a general discrepancy between the financial items disclosed by the companies and the taxonomy tags. Specifically, we noticed that the financial statements items are more disaggregated than the taxonomy tags and that this depends on the sector and the size of the companies. Unless the XBRL implementation system explicitly allows companies to use and disclose taxonomy extensions, a loss of detailed information occurs if the taxonomy is applied.     

US dollar/Euro exchange rate: a monthly econometric model for forecasting

The intent of this paper is the construction of an econometric model able to produce reliable and reasonable forecasts for the US dollar/Euro real exchange rate. In order to achieve this aim, an area-wide model is analysed. The aggregation is motivated by the fact that the Euro-zone is under a single monetary policy. Furthermore, a more parsimonious parametric model enables one to consider an important source of non-stationarity given by the presence of structural breaks using the multivariate cointegration analysis. Against the Meese-Rogoff critique, the out-of-sample one-step-ahead forecasts using actual values of the exogenous produced by the estimated VECM are reasonably satisfactory.     

Asymmetry and leverage in GARCH models: a News Impact Curve perspective

Models for conditional heteroskedasticity belonging to the GARCH class are now common tools in many economics and finance applications. Among the many possible competing univariate GARCH models, one of the most interesting groups allows for the presence of the so-called asymmetry or leverage effect. In our view, asymmetry and leverage are two distinct phenomena, both inspired by the seminal work of Black in 1976. We propose definitions of leverage and asymmetry that build on the News Impact Curve, allowing to easily and coherently verify if they are both present. We show that several GARCH models are asymmetric but none is allowing for a proper leverage effect. Finally, we extend the leverage definition to a local leverage effect and show that the AGARCH model is coherent with the presence of local leverage. An empirical analysis completes the paper.     

Income Inequality in Europe Since the Crisis

Economic inequalities are engendered by a complex process, characterised by several steps and involving the interaction of several factors. The best indicator of individual economic well-being is disposable equivalised income. Evidence shows that welfare states retain a crucial function in Europe and that they have been central in limiting the detrimental effects of the financial crisis on disposable income distribution.     

Does Choice Context Affect the Results from Incentive‐Compatible Experiments? The Case of Non‐GM and Country‐of‐Origin Premia in Canola Oil

We seek to design and implement a WTP elicitation instrument closely resembling an actual grocery shopping experience. An incentive-compatible choice experiment is used to elicit values for a non-GM attribute and a country-of-origin attribute of Canola oil. The choice context is varied to assess whether revealed-preference choice experiments are affected by choice variety. A median premium for non-GM Canola oil is found to approximate C$0.45 or C$0.62/liter according to the choice variety context; different country-of-origin effects are also found as choice context varies. Hypotheses as to why these significant effects of choice contexts occur are suggested.
Nous cherchons à concevoir et à mettre en application un instrument de révélation de la VDP qui ressemble étroitement aux choix que fait un consommateur lorsqu'il effectue son marché. Nous avons utilisé une méthode expérimentale compatible avec les incitations des participants afin de découvrir la valeur accordée à deux caractéristiques de l'huile de canola: non génétiquement modifiée et étiquetée selon le pays d'origine. La liste des choix est variée afin d'évaluer si les préférences révélées sont influencées par la gamme de choix. La prime médiane de l'huile de canola non génétiquement modifiée est d'environ 0,45 $CAN ou 0,62 $CAN le litre selon les choix proposés. Différents pays d'origine figurent aussi dans cette liste de choix. Nous avons formulé des hypothèses quant aux raisons pour lesquelles la gamme de choix a des effets importants.     

Assessing Inertia in Canadian Markets for Table Eggs

Firms may fail to adjust instantaneously to fluctuations in demand, which causes “sticky prices.” Demand can also be “sticky” due to certain types of consumer behavior. We estimate inertia in the market for shell eggs sold in Canadian supermarkets. In the absence of price information, the analysis is performed using only quantities purchased by individual consumers. From a sample of five store brands of shell eggs sold in Alberta and Ontario, we find the egg market in Alberta to show considerable inertia, while little evidence of inertia is found for the Ontario market. Implications for egg production and retail sectors are discussed. Il se peut que les entreprises ne réussissent pas è s'ajuster instantanément aux fluctuations de la demande, entraînant ainsi la rigidité des prix. Certains comportements du consommateur peuvent entraîner la rigidité de la demande. Nous avons estimé l'inertie du marché des ?ufs en coquille vendus dans les supermarchés canadiens. En l'absence d'information sur les prix, nous avons effectué l'analyse en utilisant les quantités d'?ufs achetés par des consommateurs individuels. À partir d'un échantillon de cinq marques d'?ufs en coquille vendus dans des épiceries de l'Alberta et de l'Ontario, nous avons conclu que l'inertie du marché des ?ufs en Alberta était considérable, tandis que l'inertie du marché en Ontario était faible. Nous avons examiné les répercussions de nos résultats sur la production d'?ufs et le secteur du commerce de détail.     

TIME VARIATION IN THE DYNAMICS OF WORKER FLOWS: EVIDENCE FROM NORTH AMERICA AND EUROPE

Vector autoregressive methods have been used to model the interrelationships between job vacancy rates, job separation rates and job‐finding rates using tools such as impulse response analysis. We investigate whether such impulse responses change across the business cycle or over time, by estimating time‐varying parameter–vector autoregressions for data from North America (the USA and Canada) and Europe (France, Spain and the UK). While the adjustment process of the labour market to shocks in Canada and the USA is similar, we find the adjustment process differs much more across the European countries, with greater persistence in shocks relative to the USA and Canada.
