Optimal dividend policies with transaction costs for a class of jump-diffusion processes

This paper addresses the problem of finding an optimal dividend policy for a class of jump-diffusion processes. The jump component is a compound Poisson process with negative jumps, and the drift and diffusion components are assumed to satisfy some regularity and growth restrictions. Each dividend payment is changed by a fixed and a proportional cost, meaning that if ?? is paid out by the company, the shareholders receive k???K, where k and K are positive. The aim is to maximize expected discounted dividends until ruin. It is proved that when the jumps belong to a certain class of light-tailed distributions, the optimal policy is a simple lump sum policy, that is, when assets are equal to or larger than an upper barrier $\bar{u}^{*}$ , they are immediately reduced to a lower barrier $\underline{u}^{*}$ through a dividend payment. The case with K=0 is also investigated briefly, and the optimal policy is shown to be a reflecting barrier policy for the same light-tailed class. Methods to numerically verify whether a simple lump sum barrier strategy is optimal for any jump distribution are provided at the end of the paper, and some numerical examples are given.     

Correction note for ��The large-maturity smile for the Heston model��

The papers (Forde and Jacquier in Finance Stoch. 15:755?C780, 2011; Forde et al. in Finance Stoch. 15:781?C784, 2011) study large-time behaviour of the price process in the Heston model. This note corrects typos in Forde and Jacquier (Finance Stoch. 15:755?C780, 2011), Forde et al. (Finance Stoch. 15:781?C784, 2011) and clarifies the proof of Forde et al. (Finance Stoch. 15:781?C784, 2011, Proposition 2.3).     

Endogenous free riding and the decentralized user-fee financing of spillover goods in a n-region economy

The paper analyzes the strategic effects of decentralized user-fee and enforcement policies for the financing of interregional spillover goods. We derive the equilibrium pricing and enforcement rules for a n-region economy. We show that under mild conditions on the pattern of substitution between spillover goods and contrary to the 2-region case, the decentralized equilibrium cannot be Pareto improved by coordinated policy changes. However, decentralized equilibria are suboptimal from the point of view of utilitarian welfare. We characterize the direction of the distortion for this case. The regions’ incentives for user-fee enforcement are ambiguous in general. With only two regions and if regions only charge non-residents, however, there is overinvestment in user-fee enforcement in the decentralized equilibrium. For the case of a Tullock enforcement function and linear demand for the spillover goods we show that welfare is u-shaped in a parameter that measures the technological advantage of user-fee enforcement.     

Eine Bewertung der Regelenergievermarktung im Power-to-Gas-Konzept

The integration of the increasing share of fluctuating renewable energy sources into the energy system requires more options in flexibility. A promising attempt is the power-to-gas concept (PtG) which allows the production of hydrogen and synthetic natural gas (SNG) from electricity and the storage in caverns or existing gas storage facilities. However, an economic operation in Germany is not expected before 2030, when the amount of surplus energy, mainly generated in wind parks, will be sufficient. Currently, a hardly analyzed aspect is the potential commercialization of the flexible electrolysis as controllable load on the electricity balancing market. This offers opportunities to generate additional revenues and to obtain cheap electricity in the form of balancing energy. The present article has been designed to analyze this aspect and to examine the impact of a potential commercialization of balancing energy on the gas production costs within the PtG concept. At first, the current legal framework, the funding instruments of SNG and the differences between the notion ‘Speichergas’ and ‘Biogas’ will be outlined. An overview of the current balancing market will be given and the development of prices on the secondary balancing market will be evaluated as well as expected market trends will be presented. The following calculation of gas production costs, which result from applying an optimal proposal strategy on the secondary balancing market, is model-based and uses historical data. Three scenarios are defined and examined, and the impact of variable electricity prices is analyzed. The electricity balancing market is profitable and offers many opportunities for PtG plants. The results show a decrease of SNG production costs by up to 74 % to 46,9 €/MWh. As for the hydrogen, the production costs amount to approximately 25,8 €/MWh which equals a cost reduction of up to 81 % compared to conventional PtG plants without commercialization of balancing energy.     

Home Alone: The Effects of Lone‐Insider Boards on CEO Pay,Financial Misconduct,and Firm Performance

Research summary: Corporate scandals of the previous decade have heightened attention on board independence. Indeed, boards at many large firms are now so independent that the CEO is “home alone” as the lone inside member. We build upon “pro‐insider” research within agency theory to explain how the growing trend toward lone‐insider boards affects key outcomes and how external governance forces constrain their impact. We find evidence among S&P 1500 firms that having a lone‐insider board is associated with (a) excess CEO pay and a larger CEO‐top management team pay gap, (b) increased likelihood of financial misconduct, and (c) decreased firm performance, but that stock analysts and institutional investors reduce these negative effects. The findings raise important questions about the efficacy of leaving the CEO “home alone.” Managerial summary: Following concerns that insider‐dominated boards failed to protect shareholders, there has been a push for greater board independence. This push has been so successful that the CEO is now the only insider on the boards of more than half of S&P 1500 firms. We examine whether lone‐insider boards do in fact offer strong governance or whether they enable CEOs to benefit personally. We find that lone‐insider boards pay CEOs excessively, pay CEOs a disproportionately large amount relative to other top managers, have more instances of financial misconduct, and have lower performance than boards with more than one insider. Thus, it appears that lone‐insider boards do not function as intended and firms should reconsider whether the push towards lone‐insider boards is actually in shareholders' best interests.

The influence of material resources on innovation projects: the role of resource elasticity

More (rather than fewer) material resources are thought to be the key driver in innovation project performance. Recent empirical evidence, however, suggests that the influence of material resource availability on innovation projects is not as simple and straightforwardly positive as it may seem. We build on the concept of an innovation project team's resource elasticity to disentangle the material resource–innovation output conundrum. This concept is analogous to the marketing concept of price elasticity and points to four types of innovation project teams based on their resource elasticity: In resource‐elastic teams, the relationship between material resources and innovation outcomes is positive (hence, they are ‘resource driven’ when able to dispose of adequate material resources or ‘resource victims’ when lacking these material resources). In contrast, and as a significant departure from previous work, resource‐inelastic teams show no or even a negative relationship between material resource adequacy and team performance (thus, the teams are ‘resourceful’ if they can perform with limited material resources or ‘resource burners’ if they show low success with adequate material resources). Because neither adequate nor inadequate material resources seem to be a reliable predictor of success, we synthesize empirical research efforts that point to each team type's key characteristics to derive novel implications for managing innovation projects.     

Friending the taxman: On the use of social networking services for government eID in Europe

The provision of identities online continues to be a fiercely debated topic in policy circles, with proposals emerging for public sector organizations to leverage pre-existing social networking services for their own identity management purposes. Within the broader context of private sector organizations springing up as identity providers, this article explores — from a socio-legal perspective — the merits and drawbacks of using social networking services for government eID in Europe. It then reviews the present and future European policy environment concerning official use of social networking credentials. We focus specifically on legislative measures currently being proposed in the EU to facilitate the Identification, Authentication and Signature policy, within the scope of the ongoing Electronic Signatures Directive revision process and the launch of the proposed Electronic Trust Services Regulation.     

Automation,skill requirements and labour‐use strategies: high‐wage and low‐wage approaches to high‐tech manufacturing in the automotive industry

In light of debates about advanced manufacturing and concepts like Industrie 4.0, this article compares labour‐use strategies in highly automated automotive supplier plants in a high‐wage country (Germany) and a low‐wage region (Central Eastern Europe). It shows considerable differences regarding skill requirements on the shop floor and the use of precarious employment contracts and examines three potential factors that explain them: national institutional frameworks, the power of employee representatives and the role of the plant within the companies and value chains. The analysis shows that the labour‐use strategies depend less on process technologies per se, but rather on the institutional framework and the role of the factory in the rollout and ramp‐up of new products and new process technologies. Such a role requires close cooperation between employees in the manufacturing areas and in product development, which in turn requires particularly high skills. The role of employee representatives in influencing labour‐use strategies proves less important. The article uses quantitative data from a survey of employee representatives, as well as qualitative data from in‐depth company case studies.     

Collusive tax evasion and social norms

Although collusive tax evasion by buyers and sellers of commodities and also by employers and employees is widespread all over the world, it has rarely been analyzed in the tax evasion literature. To fill this gap and to compare collusive tax evasion with independent tax evasion, this paper develops a simple noncooperative game-theoretic model and confirms the model’s predictions in a laboratory experiment. Because collusive tax evasion involves social interaction, this paper focuses on the effect of social norms and theoretically and empirically demonstrates that the tax compliance norm has a stronger negative effect on the magnitude of collusive tax evasion than on independent tax evasion. The reason for this result is that in a collusive tax evasion game with multiple equilibria social norms affect the range of equilibria and act as an equilibrium selection device, whereas social norms need to be strongly internalized to change the behavior of taxpayers who evade taxes unobservedly.
