The environmental,social and economic effects of recent technological changes in sugarcane on the State of São Paulo,Brazil

From 2007 to 2017, the Agro‐Environmental Protocol of the Sugar and Energy Sector was in force, an agreement between sugarcane mill owners and the State Government of São Paulo, Brazil, proposing to eliminate sugarcane burning as a method to facilitate the harvest. Simultaneously, the sugarcane harvest was becoming widely mechanized while, under the interests of capital accumulation, the mills were entering the information and communication technology era and providing the agricultural processes with more precise and immediate management and technological controls, similar to those implemented in the mills' administrative and industrial operations in the 1990s. Short‐term factors, including environmental factors, favoured sugarcane technological changes. As a result, there was a mass layoff of rural workers and an increasing number of people/workers in agricultural mechanization, transportation and maintenance of machinery and administrative as well. The whole process highlighted the differences between mills, resulting in small and medium sugarcane farmers and mills to become the most impacted, in operational and financial terms, by the accelerating mechanization of the sugarcane industry as a whole.     

Time-consistency of risk measures: how strong is such a property?

VFR travel: It is underestimated

Visiting Friends and Relatives (VFR) travel is a substantial form of tourism worldwide. In Australia, official data measure VFR in one of two ways - purpose of visit or type of accommodation. However, this is only a measurement of those factors; it is not a measure of the size by volume of VFR travel. Yet tourism practitioners often mistakenly use these data to state the size of VFR travel in their destination. Based on quantitative research undertaken in three contrasting destinations in Australia, estimates for the size of VFR travel in those destinations is provided. These results highlight that using official data for measuring VFR travel will underestimate this segment in any Australian destination. Using the VFR definitional model as a conceptual model, this research has estimated that VFR travel represents 48% of Australia’s total overnight tourism market.     

Revising the Corporate Social Performance Model – Towards Knowledge Creation for Sustainable Development

The objective of this paper is to offer a revision of the corporate social performance (CSP) model. CSP exemplifies how corporate social responsibility translates into an organization's practice by focusing on three key features of performance: principles, processes and outcomes. However, the development of the model has not kept pace with the literature on social and environmental responsibility. This study builds on an argument that if corporate social responsibility in general – in which CSP plays an important role – is to respond to the challenges of sustainable development, the CSP of businesses could be more profoundly planned in order to design knowledge outcomes that contribute to meeting those challenges. The paper thus answers the recent call for the development of a CSP model by revising some of the key elements in the existing model and also by adding a knowledge creation dimension.

Swap pricing and hedging of general DCFs

This paper shows that under payoff and/or interest rate uncertainty the splitting up of discounted cash flows (DCFs) into period addenda not only permits to quantify the contribution of each period to the total (random) DCF, but also allows us to price it and hedge the its risk. The contribution effect was already well known, while the pricing and hedging issue is new in this context. We first notice that—through the decomposition—each cash flow process can be interpreted as a swap one. We then resort to the risk-neutral pricing and hedging technique as applied to (exotic) swaps.     

AN EXPERIMENT ON CORRUPTION AND GENDER

A number of papers with field data have found differences in the corrupt activities of males and females; nonetheless they have drawbacks that may be overcome in a laboratory experiment. The aim of this paper is to see experimentally whether women and men, facing the same situation behave in a different way, as suggested in the field‐data studies or, on the contrary, whether they behave in the same way. The results found in the experiment show that women are indeed less corrupt than men.     

Firm heterogeneity in productivity across Europe: evidence from multilevel models

This paper analyses the Total Factor Productivity (TFP) heterogeneity of a sample of manufacturing firms operating in seven EU countries (Austria, France, Germany, Hungary, Italy, Spain and the UK). TFP data refer to 2008. The empirical setting is based on the multilevel modeling which provides two main results. Firstly, we show that TFP heterogeneity is largely due to firm-specific features (85% of TFP variability in the empty model). Interestingly, we find that some key-drivers of firm performance (size, family management, group membership, innovations and human capital) are significantly related to TFP, but do not, on the whole, absorb much of firm TFP variance, implying that differences in productivity are due to notable yet unobservable firm characteristics. Secondly, as far the role of localization is concerned, we demonstrate that the country effect is more influential than region effect in explaining individual productivity. Net of the country effect, the localization in different European regions explains about 5% of TFP firm heterogeneity. When considering the case of three individual countries, France, Italy and Spain, location in different regions explains 5.3% of TFP heterogeneity in Italy, while this proportion is lower (3.6%) in France and higher (9.9%) in Spain.     

On the short-maturity behaviour of the implied volatility skew for random strike options and applications to option pricing approximation

In this paper, we propose a general technique to develop first- and second-order closed-form approximation formulas for short-maturity options with random strikes. Our method is based on a change of numeraire and on Malliavin calculus techniques, which allow us to study the corresponding short-maturity implied volatility skew and to obtain simple closed-form approximation formulas depending on the derivative operator. The numerical analysis shows that these formulas are extremely accurate and improve some previous approaches for two-asset and three-asset spread options such as Kirk’s formula or the decomposition method presented in Alòs et al. [Energy Risk, 2011, 9, 52–57]. This methodology is not model-dependent, and it can be applied to the case of random interest rates and volatilities.
