Mixed Competition and Patent Licensing

This paper studies the patent licensing decision of an insider patentee when two firms engage in a mixed (Cournot–Bertrand or Bertrand–Cournot) competition where one firm adopts the quantity strategy while the other uses the price strategy and vice versa. If either the fixed fee or royalty is applied, then the licensor prefers the fixed fee when the licensor takes the quantity strategy, while the licensee uses the price strategy (Cournot–Bertrand). If the two‐part tariff is applied, then the two‐part tariff is more likely to be adopted by the licensor under Cournot–Bertrand than under Bertrand–Cournot competition.     

Estimating Purchasing Power Parities from Household Expenditure Data Using Complete Demand Systems with Application to Living Standards Comparison: India and Vietnam

This study departs from the previous literature on purchasing power parity (PPP) by proposing a demand system based methodology for calculating the PPP that takes account of consumer preferences and allows for the substitution effect of price changes. The methodology is used to calculate the PPP between the Indian Rupee and the Vietnamese Dong. The study allows for regional variation in preferences and price changes both inside the country and between countries. It proposes and applies a methodology for constructing prices from unit values after adjusting them for quality and demographic effects. The adjusted unit values are used as prices in the demand estimations, and the demand parameter estimates are used to calculate both spatial prices within each country and the PPP between the two countries within a consistent framework. The study illustrates the usefulness of preference consistent methods to calculate the PPP by applying the PPPs to compare living standards between India and Vietnam. The significance of the results follows from the fact that the levels of living comparisons are quite sensitive to the PPP used in converting the Rupee expenditure into Vietnamese Dong. The present results on food PPPs question the relevance of the PPPs from the ICP project in cross‐country welfare comparisons especially in a period of high food inflation.     

Project Decision Chain

To add value to project performance and help obtain project success, a new framework for decision making in projects is defined. It introduces the project decision chain inspired by the supply chain thinking in the manufacturing sector and uses three types of decisions: authorization, selection, and plan decision. A primitive decision element is defined where all the three decision types can be accommodated. Each task in the primitive element can in itself contain subtasks that in turn will comprise new primitive elements. The primitive elements are nested together in a project decision chain.     

On the Phelps–Koopmans theorem

We examine whether the Phelps–Koopmans theorem is valid in models with nonconvex production technologies. We argue that a nonstationary path that converges to a capital stock above the smallest golden rule may indeed be efficient. This finding has the important implication that “capital overaccumulation” need not always imply inefficiency. Under mild regularity and smoothness assumptions, we provide an almost-complete characterization of situations in which every path with limit in excess of the smallest golden rule must be inefficient, so that a version of the Phelps–Koopmans theorem can be recovered. Finally, we establish that a nonconvergent path with limiting capital stocks above (and bounded away from) the smallest golden rule can be efficient, even if the model admits a unique golden rule. Thus the Phelps–Koopmans theorem in its general form fails to be valid, and we argue that this failure is robust across nonconvex models of growth.     

Mentors,supervisors and role models: do they reduce the effects of psychological contract breach?

Psychological contract breach has become a significant problem for many organisations in today's business environment because it fosters a belief within employees that the organisation does not support them. Accordingly, we examine whether organisations can diminish the negative impact of psychological contract breach on perceived organisational support (POS) by providing employees with mentors, supportive supervisors and role models. In Study 1, we found that mentor relationships moderated the relationship between psychological contract breach and POS six months later. In Study 2, we showed that mentor relationships and supervisor support reduced the negative impact of contract breach on POS. Contrary to expectations, employees who maintained relationships with role models reported lower levels of POS in response to psychological contract breach than those employees who reported that they did not have role models in their organisations. Implications for research and practice are discussed.     

Tax avoidance,tax management and corporate social responsibility

This study examines the effect of three measures of corporate social responsibility (CSR) — corporate governance, community and diversity on tax avoidance in firms that use auditor‐provided tax services. This is one of the first studies, to our knowledge, to empirically relate tax avoidance, tax management and CSR literature. By separating the strengths and concerns for each CSR measure, we are able to analyze the effects of a firm's negative and positive social actions on tax avoidance. We find that the interaction of community concerns with tax management fees positively affects both GAAP and Cash ETR, while the interaction of corporate governance strengths and diversity concerns with tax management fees negatively affects Cash ETR. Our results are similar when we use Excess ETR that is not explained by firm specifics. We find additional evidence that CSR affects tax avoidance when we divide firms into portfolios based on CSR levels. Our findings suggest that future studies on tax avoidance and tax management should incorporate CSR.
