ON THE ROBUSTNESS OF RANGE‐BASED VOLATILITY ESTIMATORS

We empirically examine Parkinson's range‐based volatility estimate in the federal funds market, which is unique because institutional regulations create a predictable pattern in interday volatility. We find that range‐based volatility estimates and standard deviations produce the expected volatility pattern. We also find that at trading pressure points where microstructure noise should be greatest, range‐based estimates are less than the standard deviations. Thus, we support the argument that range‐based volatility estimates remove the upward bias created by microstructure noise. We find that the Parkinson method is the most efficient range‐based volatility measure among a set of alternates in this market.     

The liability of closeness: Business relatedness and foreign subsidiary performance

It is widely accepted that business relatedness, defined as the extent to which a foreign subsidiary is related to its parent's core business, has a positive effect on subsidiary performance. With a sample of 165 Japanese subsidiaries located in China, however, we found that modestly related subsidiaries, on average, outperformed both unrelated and closely related subsidiaries, and that closely related subsidiaries performed poorly especially when the parent had a heavy majority ownership in the subsidiary and the subsidiary was at its early stage of operating in the host market. Our results indicate that being too closely related to the parent could be potentially detrimental, suggesting a liability of closeness.     

Optimal route decision with a geometric ground-airborne hybrid model under weather uncertainty

Adverse weather is the dominant cause of delays in the National Airspace System (NAS). Since the future weather condition is only predictable with a certain degree of accuracy, managing traffic in the weather-affected airspace is a challenging task. In this paper, we propose a geometric model to generate an optimal combination of ground delay and route choice to hedge against weather risk. The geometric recourse model (GRM) is a strategic Probabilistic Air Traffic Management (PATM) model that generates optimal route choice, incorporating route hedging and en-route recourse to respond to weather change: hedged routes are routes other than the nominal or the detour one, and recourse occurs when the weather restricted airspace becomes flyable and aircraft are re-routed to fly direct to the destination. Among several variations of the GRM, we focus on the hybrid Dual Recourse Model (DRM), which allows ground delay as well as route hedging and recourses, when the weather clearance time follows a uniform distribution. The formulation of the hybrid DRM involves two decision variables - ground delay and route choice - and four parameters: storm location, storm size, maximum storm duration time, and ground-airborne cost ratio. The objective function has two components: expected total ground delay cost and expected total airborne cost. We propose a solution algorithm that guarantees to find the global optimum of the hybrid-DRM. Based on the numerical analysis, we find that ground-holding is effective only when combined with the nominal route. Otherwise, it is optimal to fly on the route determined by the DRM without ground delay. We also find the formula of the threshold ground-airborne cost ratio, which we call the Critical Cost Ratio (CCR), that determines the efficacy of ground delay: the higher the CCR, the more effective the strategies involving ground delay. We conclude that both ground delay and route hedging should be considered together to produce the best ATM decisions.     

The Political Economy of State Government Subsidy Adoption: The Case of Ethanol

In this study, we examine the factors that determine the adoption of state economic development incentives in the ethanol industry. We compile data on the implementation dates for subsidies/tax credits for all states for the years 1984–2007, a period that covers the complete emergence of the biofuel industry in the United States and that was characterized by the passage of numerous state‐level subsidies and tax breaks aimed at increasing ethanol production. Using Cox proportional hazard regression analysis, we find that states are more likely to adopt ethanol subsidies when corn production is high, when corn prices are low and gasoline prices are high, when a state is affiliated with the National Corn Growers Association, when a check‐off is present, when a state has a high environmental score, and when state government is under the control of Democrats.     

Opening up the black box: a UK case study of top managers’ attitudes to their performance related pay

This paper examines the attitudes of the top managers within one large financial services organization in the UK to fixed and variable components of their compensation package. The rationale for performance-related pay for senior managers is to align their interests with those of the shareholders, but little is known about the views of top managers on the effectiveness of such incentives. The results suggest that the design of effective bonus systems is not just a technical issue: perceptions of market fairness with respect to the compensation package and the clear communication of goals are important in getting senior managers to focus on shareholder interests.     

Married couples’ involvement with family vacations

Abstract

The involvement construct has received a great deal of attention in recent years. However, the majority of research on this topic has focused on the individual and has ignored spouses’ shared leisure involvement. In addition, little work has been done on involvement in the product‐class context of family vacations. This study examined the underlying dimensions of married couples’ involvement with family vacations and how these dimensions relate to selected personal variables. Factor analysis revealed two underlying dimensions. Stepwise multiple regression revealed that pleasure‐importance was positively related to gender role ideology and education and negatively related to presence of children in the home. A positive relation existed between the second dimension, sign value, and age. The study provides insight into both the nature of the involvement construct and how it might be used in future research.     

Domain‐Relevant Commitment and Individual Technical Innovation Performance

Individual innovators play a critical organizational role in that they generate and often champion technology and product ideas. Amidst an ongoing stream of organizational and team innovation research, few empirical studies focus on differences in individual innovation performance despite the importance of the individual innovator to a firm's innovation efforts. Based on goal commitment theory, we introduce a new domain‐relevant commitment construct and develop a conceptualization of conditional indirect effects. Our model suggests that relevant individual abilities enhance commitment to technical innovation and innovation performance while also insulating against the impact of situational variables, making employees' commitment to innovation performance less dependent upon context. Hypotheses are tested using two sources of data and a sample of 339 R&D professionals from a Fortune 100 industrial firm. Results suggest that commitment to innovation is a key motivational factor in explaining individual technical innovation performance. Situational characteristics impact motivation differently for individuals with lower vs. higher ability levels, even in this context in which truly low‐ability individuals, in the absolute sense, have been screened out by the employment selection process. The relationship between commitment and innovation performance is strengthened by higher levels of individual ability.     

On the Stationarity of Current Account Deficits in the European Union

In this paper, we test for the stationarity of EU current account deficits. Our testing strategy addresses two key concerns with regard to unit‐root panel data testing, namely (i) the identification of which panel members are stationary, and (ii) the presence of cross‐sectional dependence. For this purpose, we employ an AR‐based bootstrap approach to the Hadri (2000 ) test. While there is only mixed evidence that current account stationarity applies when examining individual countries, this does not appear to be the case when considering panels comprising both EU and non‐EU members.
