Framing the UK’s counter-terrorism policy within the context of a wicked problem

Terrorist attacks can be seen as the ultimate wicked problem. After 9/11, terrorists moved from so-called ‘spectacular’ events to relatively low-intensity attacks against individuals and groups. The emergence of what has become known as the ‘home-grown’ terrorist has added a further dimension to the ‘wicked’ nature of the problem. This paper considers the UK’s CONTEST and PREVENT strategies as a policy response to the threats from terrorism and the impact that the policies themselves can have on the radicalization of individuals. The author highlights some of the limitations of the PREVENT strand of the overall strategy and the constraints that are imposed on government policies by failing to take a holistic perspective on the nature of the problem.     

Corporate Governance and the Goal of the Firm: In Defense of Shareholder Wealth Maximization

This essay is based on my keynote address at the 2016 annual meeting of the Eastern Finance Association. I propose that misunderstandings about the traditional model of corporate governance, with its emphasis on shareholder wealth maximization, contribute to negative societal attitudes about corporations. I discuss the implications of shareholder wealth maximization for other corporate stakeholders, the dangers of deviating from shareholder wealth maximization, and the roles that the media and the government play in the governance of corporations.     

Optimal mixed taxation,credit constraints,and the timing of income tax reporting

We study optimal income and commodity tax policy with credit‐constrained low‐income households. Workers receive an even flow of income during the tax year, but report their incomes and make tax payments (receive transfers) at the end of the year. They spend their disposable income on multiple commodities over the year. We show that differentiated subsidies on commodities can be optimal even if the Atkinson–Stiglitz Theorem conditions apply. When the optimal policy leaves low‐income households with binding credit constraints, it may be optimal to subsidize differentially the good that they consume in higher proportion. Uniform subsidies would also relax the credit constraint, but would be more costly to the government since they would equally benefit unconstrained households. Numerical examples suggest that commodity tax differentiation increases with basic needs and with the interest rate at which government borrows.     

Investment and Productivity in Canadian and U.S. Food Manufacturing

A restricted cost function model of Canadian and US. food manufacturing shows that productivity growth rates in Canada have remained well below those in the United States for the past decade and a half_: At mean factor prices, output, and capital quantities, processing costs would be 22% lower in the U.S. than in Canada. Technical change in both countries has been labor-saving and material-using, although slightly more so in the US. than in Canada. The labor-saving bias of technical improvements puts Canada at a disadvantage to its southern neighbor, since food manufacturing wages in Canada tend to be lower and material prices higher than in the United States. Enhancing its competitiveness will require that Canada reduce raw food and packaging costs or invest more in research and development .
L'estimation d'une function constraint de coût démontre que le taux de productivité du secteur de la transformation des aliments et boissons au Canada est demeuré inférieur à celui des Etats-Unis depuis une quinzaine d'années. En effet, à la moyenne du prix des intrants, du stock de capital et de la quantité produite, le coût de production américain est de 22 % inférieur à celui du Canada. Dans les deux pays, le changement technologique a permis de substituer le matériel à la main-d'oeuvre, et ceci de façon plus prononcée aux Etats-Unis. En bout de ligne, ceci désavantage le secteur canadien des aliments et boissons puisque les salaires sont généralement inférieurs au Canada alors que le matériet est plus coûteux. Le Canada pourrait améliorer sa compétitivité face aux Etats-Unis en réduisant le prix des denrées et des entrées intermédiaires ou en augmentant l'investissement dans la recherche et le développement .     

Valuation and incentive effects of hurdle rate executive stock options

Traditional executive stock options are often criticized for inherently weak links between pay and performance. Hurdle rate executive stock options represent a viable improvement. However, valuing these options presents extraordinary analytic difficulties. With a constant dividend yield the strike price becomes a path-dependent function of the stock price and exact analytic valuation is intractable. To solve this problem, we apply the Monte Carlo valuation approach developed by Longstaff and Schwartz (Rev Financ Stud 4:113–147, 2001) to estimate the value of path-dependent American options. We also extend the methodology to incorporate the theoretical framework by Ingersoll (J Bus 79:453–487, 2006) to permit subjective valuation influenced by an executive’s risk aversion.

Sensitivities for Bermudan options by regression methods

In this article, we propose several pathwise and finite difference-based methods for calculating sensitivities of Bermudan options using regression methods and Monte Carlo simulation. These methods rely on conditional probabilistic representations that allow, in combination with a regression approach, for efficient simultaneous computation of sensitivities at many initial positions. Assuming that the price of a Bermudan option can be evaluated sufficiently accurate, we develop a method for constructing deltas based on least squares. We finally propose a testing procedure for assessing the performance of the developed methods and give a numerical illustration.     

Impacts of intermediate trade on sector structure

Structural changes, i.e. long-run changes in the agriculture-manufacturing-services-structure, are a key property of growth and development processes with massive impacts on economy and society and are part of actual debates regarding policy in developing and developed economies. While traditional literature has attempted to explain structural changes by using autarkic models, recent literature has emphasised the importance of deriving theories of structural change using open economy settings. We elaborate on the impacts of intermediate trade on sector structure. In particular, we study how import of intermediate products, which is increasingly feasible due to improvements in transport technology and political integration, affects sector structure in a multi-sector growth model with capital accumulation. This topic has not been studied in the previous literature on structural change in open economies, despite the fact that intermediate imports and capital accumulation are central aspects of modern developing and developed economies. We show that the impacts of intermediate trade on sector structure depend on three factors: productivity gains from trade, specialisation in international trade and development stage. Depending on the constellation of these factors, intermediate trade may accelerate, decelerate or have no effect on structural change. Thus, the effects of intermediate trade may vary strongly across countries.     

Scoring More After Service Failures: Why Do Customers Overclaim?

ABSTRACT

More and more customers attempt to claim what they can, rather than what they are offered by the service firm after service failures. The present article empirically investigates the role of situational characteristics in triggering the intention to overclaim through a mediating process of customer's cognitive and emotional responses to the service failure. The model goes beyond predicting the likelihood of overclaiming behavior and offers some insights related to the magnitude or the extent of such claims. The results indicate that cognitive and affective drivers of overclaiming behavior have different impacts on the magnitude or the extent of such claims.
