A flexible lattice framework for valuing options on assets paying discrete dividends and variable annuities embedding GMWB riders

In a market where a stochastic interest rate component characterizes asset dynamics, we propose a flexible lattice framework to evaluate and manage options on equities paying discrete dividends and variable annuities presenting some provisions, like a guaranteed minimum withdrawal benefit. The framework is flexible in that it allows to combine financial and demographic risk, to embed in the contract early exercise features, and to choose the dynamics for interest rates and traded assets. A computational problem arises when each dividend (when valuing an option) or withdrawal (when valuing a variable annuity) is paid, because the lattice lacks its recombining structure. The proposed model overcomes this problem associating with each node of the lattice a set of representative values of the underlying asset (when valuing an option) or of the personal subaccount (when valuing a variable annuity) chosen among all the possible ones realized at that node. Extensive numerical experiments confirm the model accuracy and efficiency.

     

The financial and green effects of cultural values on mission drifts in European social enterprises

The sustainable social enterprises (SEs) literature shows that SEs have to simultaneously pursue economic, social, and environmental aims. However, tensions between these objectives can make this a challenging task and lead towards mission drift. This work investigates if the cultural dimension can forecast the mission drift. We empirically analyze this relationship in three stages. In the first stage, we identify a homogeneous dataset of 287 sustainable SEs from seven EU countries from 2011 to 2020. Then, in the second stage, we apply the data envelopment analysis (DEA) methodology to calculate the efficiency of the SEs. An efficient SE has to simultaneously achieve social, environmental, and economic aims. We calculate a proxy of the mission drift and generate a dichotomous category variable that assigns value 1 to the SE not affected by mission drift, 0 otherwise. In the last stage, we implement the 2SLS logistic regression between the variable that identifies the SEs affected by mission drift and three cultural dimensions: avoidance of uncertainty, masculinity, and short-term orientation.     

The strategic choice of payment method in takeovers: The role of environmental,social and governance performance

Payment method choice in takeovers is mainly driven by both asymmetric information between the acquirer and the target and the acquirer's financial capability. In this paper, we examine whether increased transparency and better access to finance induced by environmental, social and governance (ESG) performance are associated with the strategic choice of payment method in takeovers. More specifically, we investigate how the acquirer's and the target's ESG coverage and different levels of ESG performance affect the probability of cash offers in a sample of 836 US takeovers from 1992 to 2014. In examining the target, our results suggest that ESG coverage is positively associated with the probability of cash offers, whereas we find a negative relationship for ESG concerns and no effect for ESG strengths. Upon examining the acquirer, ESG coverage and ESG concerns both increase the probability of cash offers; however, we do not find results supporting our prediction regarding the acquirer's ESG strengths. We infer that ESG coverage and level affect strategic considerations in the choice of the payment method in takeovers because they not only reduce information asymmetry, but also enhance financing capability.
