A core-theoretic solution for the design of cooperative agreements on transfrontier pollution

For a simple economic model of transfrontier pollution, widely used in theoretical studies of international treaties bearing on joint abatement, we offer in this paper a scheme for sharing national abatement costs through international financial transfers that is inspired by a classical solution concept from the theory of cooperative games—namely, the core of a game. The scheme has the following properties: total damage and abatement costs in all countries are minimized (optimality property), and no coalition or subset of countries can achieve lower total costs for its members by taking another course of action in terms of emissions or transfers, under some reasonable assumption about the reactions of those not in the coalition (core property). In the concluding section economic interpretations of the scheme are proposed, including its connection with the free-riding problem.     

Examining the motivators of training transfer in an enterprise systems context

Enterprise systems (ES) are large software packages that have been widely adopted, but are complex to deploy. One way to obtain more value from them is to train end-users. However, little is known about the effectiveness of ES training. This study examines post-training behaviour in the ES environment through the concept of training transfer and the theoretical framework of self-determination theory. It proposes that end-users’ computer self-efficacy (CSE) and mastery orientation (MO), as well as the perceived ease-of-use (PEOU) of a system, influence their motivation to transfer the skills they have gained during training to their work environment and to use the system. Data was collected from 170 ES end-users, who had previously attended ES training, through a survey. Partial least squares modelling was used to analyse the data, and all of the hypotheses were supported. This study is among the first few studies that investigate the more distal impact of information systems training.     

Managerial perceptions of employees’ affective commitment and product innovation

In this paper we examine how managers perceive employees’ affective commitment and how this perception determines their trust as a managerial attitude toward organizational learning capability (OLC). Likewise, we study how managerial trust affects product innovation and OLC. In other words, we carry out a double mediation: firstly, we examine whether managerial trust is a mechanism through which managerial perceptions of employees’ affective commitment influences on OLC, and secondly, we study if OLC mediates between managerial trust and product innovation. By using structural equation modeling (partial least squares) on a sample of 192 Spanish firms we conclude that: (1) if managers perceive employees to be affectively committed, they will be willing to enhance OLC and to trust them; (2) managerial trust favors OLC and product innovation and (3) OLC appears to exert a full mediation between managerial trust and product innovation.     

Further empirical evidence on block transactions below the MBR: the Spanish market

There is a relatively unknown market for partial control or corporate influence in Spanish listed firms, where the control transaction size is below the legal threshold that triggers a mandatory tender offer, as this kind of deal looks for exercising some degree of control, but not a full control. The goal of this paper is to go further in its empirical analysis by exploring its distinguishing features, using as the criterion to define its transactions obtaining a seat in the board of directors. We find that these deals are mainly located in the segment of the market of large trades where the rules for private negotiations are easier to implement; the size of the block is relatively large and it is negotiated as a whole block. Besides, the most common buyer has no previous stake in the firm. We find no evidence that the buyers pay, in median, for a seat on the board of directors, but the variability of the premiums for those blocks is higher and shows that buyers that had no control position in the target firm pay more for being among largest shareholders (partial control) and less for not being among them (influence).

FAST MONTE CARLO GREEKS FOR FINANCIAL PRODUCTS WITH DISCONTINUOUS PAY‐OFFS

We introduce a new class of numerical schemes for discretizing processes driven by Brownian motions. These allow the rapid computation of sensitivities of discontinuous integrals using pathwise methods even when the underlying densities postdiscretization are singular. The two new methods presented in this paper allow Greeks for financial products with trigger features to be computed in the LIBOR market model with similar speed to that obtained by using the adjoint method for continuous pay‐offs. The methods are generic with the main constraint being that the discontinuities at each step must be determined by a one‐dimensional function: the proxy constraint. They are also generic with the sole interaction between the integrand and the scheme being the specification of this constraint.     

Optimal investment and risk control for an insurer with partial information in an anticipating environment

Abstract

This paper considers an optimal investment and risk control problem under the criterion of logarithm utility maximization. The risky asset process and the insurance risk process are described by stochastic differential equations with jumps and anticipating coefficients. The insurer invests in the financial assets and controls the number of policies based on some partial information about the financial market and the insurance claims. The forward integral and Malliavin calculus for Lévy processes are used to obtain a characterization of the optimal strategy. Some special cases are discussed and the closed-form expressions for the optimal strategies are derived.     

Improved Neymanian analysis for 2K factorial designs with binary outcomes

2^K factorial designs are widely adopted by statisticians and the broader scientific community. In this short note, under the potential outcomes framework, we adopt the partial identification approach and derive the sharp lower bound of the sampling variance of the estimated factorial effects, which leads to an “improved” Neymanian variance estimator that mitigates the overestimation issue suffered by the classic Neymanian variance estimator.
