Bond Price and Impulse Response Function for the Balduzzi, Das, Foresi and Sundaram (1996) Model

In this paper, we analyse the Affine Term Structure Model (ATSM) proposed by Balduzzi, Das, Foresi and Sundaram (BDFS, 1996) and provide the closed-form expression of the bond price. In addition, we extend the notion of Impulse Response Function to the class of ATSM. We show that it is closely related to the duration measure, and we compute it explicitly in the BDFS model.     

Assessing the productivity of the Italian hospitality sector: a post-WDEA pooled-truncated and spatial analysis

This paper analyses the productivity of the hospitality sector (hotel and restaurants) in Italy at a regional level by using a mix of non-parametric and parametric approaches. A novel pooled-truncated and spatial analysis is employed, based upon a window data envelopment analysis (WDEA), where pure technical efficiency is computed. The WDEA results show that Lombardy is the best relative performer. However, overall Italian regions reveal important sources of inefficiency mostly related to their inputs. As a post-WDEA, the pooled-truncated estimation indicates that the rate of utilisation and regional intrinsic features positively affect hospitality efficiency. Nevertheless, the spatial analysis does not support evidence of spill-over effects amongst Italian regions.     

Segmentation and motivation of foreign tourists in world heritage sites. A case study,Quito (Ecuador)

This paper presents an analysis of the current relationships between three fundamental constructs in the decision-making process of the visitor – motivation, satisfaction and loyalty – of a tourist destination World Heritage Site like the city of Quito, Ecuador. The results demonstrate the existence of three motivational dimensions among foreign visitors to visit the city: firstly cultural, secondly circumstantial and finally hedonic-gastronomic. Additionally, and tending to the motivational schemes, four types of foreign visitors have been identified: a hedonic-gastronomic cultural tourist, a hedonic-gastronomic tourist, a circumstantial hedonic-gastronomic cultural tourist and an alternative tourist. The reasons or motives of the visit reveal that only the hedonic-gastronomic dimension discriminates significantly as far as the degree of perceived satisfaction and loyalty declared by the visitors are concerned.     

COMPARATIVE EFFICIENCY OF AGRICULTURAL COOPERATIVES AND CONVENTIONAL FIRMS IN A SAMPLE OF QUASI‐TWIN COMPANIES

The resilience of cooperatives and their positive contribution to employment in times of crisis is well established. However, their overall economic performance relative to conventional firms is still controversial, casting doubt on the ability of this alternative organizational form to govern the fundamental drivers of productivity. To shed new light on the issue, we study the comparative technical efficiency of agricultural cooperatives (ACs) and conventional firms (CFs), drawing on a unique data set comprising all wine‐producing companies in Sardinia (Italy) from 2004 to 2009. Due to the similarity of the habitats in which the firms operate and the careful measurement of several key inputs, the observed units are ‘twins’ in all non‐organizational respects, providing an ideal setting for comparison. Having generated efficiency scores through Data Envelopment Analysis (DEA), we regressed the scores on external covariates and ownership type using a pooled truncated maximum likelihood formulation. Our findings, which survive correction for spatial correlations, indicate that cooperatives are less technically efficient than their capitalist counterparts and struggle more to adapt to extreme weather fluctuations. Both results are particularly worrying in light of the main challenges facing the wine industry in the near future: liberalization of EU planting rights and climate change.     

Over the ROC methodology: Productivity,economic size and firms’ export thresholds

We identify the minimum combinations of productivity and “economic size” that Italian manufacturing firms need to achieve in order to access international markets. These “export thresholds” are estimated by applying, for the first time in economics, the ROC (receiver operating characteristics) methodology. In this way, we detect a model‐based (rather than a subjectively determined) cut‐off that allows to identify exporters and nonexporters and provides a measure of each firm’s distance from the export threshold. This methodology also paves the way to investigate other determinants of thresholds, thus helping to design more effective policy interventions to reduce barriers to trade.     

Impact of institutional reforms and industry structural factors on market returns of emerging market rivals during acquisitions by foreign firms

This paper seeks to understand the joint impact of institutional reforms and industry structural factors on market returns earned by rivals in an emerging market during foreign acquisitions. We use a sample of 238 foreign acquisitions in India during the period 2004–2013 and find empirical evidence to support the notion that institutional reforms, foreign competition and business group competition positively impact the market returns of the rivals of acquired firms. Additionally, we find that the effects of foreign competition and business group competition on rivals’ market returns are shaped by the degree of institutional reforms in the industry, indicating that firms’ market returns in emerging markets during foreign acquisitions can be better understood through the incorporation of the joint role of industry structural factors and institutional reforms.     

Portfolio management with tail dependence

Many publications, that treated with Portfolio Management, were devastating for all asset allocation models in the context of portfolios. The elimination of extreme events (asymmetric or tail dependence) during the portfolio construction process can reduce the skills of asset managers to reduce risk through diversification. The copula theory allows us to calculate an alternative to measure the dependence of extreme events in assets through the index lower tail dependence. We check that the strategies with tail dependence overcame Talmud rule, the Markowitz model and the model of Tu and Zhou by simulating 1,000 portfolios with 3, 5, 10 and 20 randomly selected assets from DJIA for the period 03/1990 until 12/2016. We conclude that models of tail dependence and Markowitz had more performance ex-ante than Talmud and the Tu and Zhou model for portfolios with 3, 5, 10 and 20 assets. Tail dependence models overcome Markowitz, in terms of cumulative return, in over 60% of months considered in the analysis. The results indicate that the Talmud rule should be discarded in a context of constructing portfolios with individual stocks ahead strategies with tail dependence.
