Control and commitment HR practices,job satisfaction and turnover intentions: a comparison between local and multinational firms in China

There is a growing body of literature and debate around control versus commitment human resource management (HRM) systems and their impacts on employees. However, the impacts of these constructs have not been widely examined in more emerging economies. Taking a specific sample of educated professionals working for multinational and local firms in China, this study investigated employee perceptions of control and commitment HR practices, job satisfaction and turnover intentions. A total of 311 respondents completed a structured survey questionnaire. Results revealed that those working for multinational firms reported more positive perceptions of their employers' control and commitment HR practices. In multinational firms, the use of commitment HR practices predicted lower intentions to leave. However, in domestic firms a lack of control HR practices predicted higher turnover intentions. Theoretically, the study adds to discussions about the nature and roles of these constructs, their impacts on HR outcomes and how institutional mechanisms might shape the degree of HRM homogeneity and hybridity across organizations in China. Practically, the study provides guidance to international and local firms on how to improve their HRM effectiveness to achieve a higher retention of their most talented professionals.     

Pricing options in incomplete equity markets via the instantaneous Sharpe ratio

We use a continuous version of the standard deviation premium principle for pricing in incomplete equity markets by assuming that the investor issuing an unhedgeable derivative security requires compensation for this risk in the form of a pre-specified instantaneous Sharpe ratio. First, we apply our method to price options on non-traded assets for which there is a traded asset that is correlated to the non-traded asset. Our main contribution to this particular problem is to show that our seller/buyer prices are the upper/lower good deal bounds of Cochrane and Saá-Requejo (J Polit Econ 108:79–119, 2000) and of Björk and Slinko (Rev Finance 10:221–260, 2006) and to determine the analytical properties of these prices. Second, we apply our method to price options in the presence of stochastic volatility. Our main contribution to this problem is to show that the instantaneous Sharpe ratio, an integral ingredient in our methodology, is the negative of the market price of volatility risk, as defined in Fouque et al. (Derivatives in financial markets with stochastic volatility. Cambridge University Press, 2000).     

Zoning, TDRs and the density of development

This paper explores the effect of low density zoning regulations and other factors on subdivision density. Using a unique dataset of new subdivisions built over a 34-year period in Calvert County, Maryland, we econometrically estimate a density function using both OLS and censored regression. The variability in density permitted by the county's zoning and TDR rules over the sample period allows us to assess the relative importance of market factors and regulatory constraints on density. We use the censored model to predict what density patterns would have been without zoning.     

Investment sharing in broadband networks

This paper presents a model of competition between an incumbent firm and an Other Licensed Operator (OLO) in the broadband market, where the incumbent has an investment option to build a Next Generation network (NGN) and it can do so by making an investment sharing agreement with the OLO, or alone. Two different kinds of investment sharing contractual forms are analyzed, a basic investment sharing, where no side-payment is given for the use of the NGN between co-investors, and joint-venture, where a side-payment is set by the co-investing firms. Results show that investment sharing can potentially be beneficial in terms of competition and investments, but the number of firms involved matters and so does the choice of the NGN access price, for insiders and outsiders of the agreement. Even when the presence of firms outside of the agreement force insiders to compete more fiercely, there might be a concern with the potential exclusion of the outsiders from the NGN.     

A Bayesian Approach to Understanding Time Series Data

This paper explores the use of Bayesian models to analyze time series data. The Bayesian approach produces output that can be readily understood by actuaries and included in their own experience studies. We illustrate this Bayesian approach by analyzing U.S. unemployment rates, a macroeconomic time series. Understanding time series of macroeconomic variables can help actuaries in pricing and reserving their products. For example, a change in the level and/or variance of the unemployment series is of interest to actuaries, because its movement can explain a changing pattern of lapse rates of incidence rates. Our Bayesian analysis, based on models developed by McCulloch and Tsay (1993, 1994), allows for shifts in the level and in the error variance of a process. We develop a measure of model fit, based on the Akaike Information Criterion, that can be used in choosing between alternative models. Posterior prediction intervals for the fitted values are also created to pictorially show the range of paths that could result from the choice of a particular model.     

Trusting the fair supervisor: the role of supervisory support in performance appraisals

Applying social exchange theory and organisational support theory to a performance appraisal context, we hypothesised that perceived supervisory support would mediate the relationships between both interpersonal and informational justice, and trust in the supervisor. The data were collected from 526 full‐time working adults, who answered questions about the fairness of their organisation's current performance appraisal process. Using structural equation modelling, both calibration (n = 278) and cross‐validation (n = 248) field samples showed that perceived supervisory support mediated the justice–supervisor trust relationships. Our findings suggest that perceived supervisory support serves as a mechanism through which perceptions of interpersonal and informational justice foster trust in supervisors. Implications for organisational practice and areas for future research are discussed.     

Optimal and Simple,Nearly Optimal Rules for Minimizing the Probability Of Financial Ruin in Retirement

Abstract

The increasing risk of poverty in retirement has been well documented; it is projected that current and future retirees’ living expenses will significantly exceed their savings and income. In this paper, we consider a retiree who does not have sufficient wealth and income to fund her future expenses, and we seek the asset allocation that minimizes the probability of financial ruin during her lifetime. Building on the work of Young (2004) and Milevsky, Moore, and Young (2006), under general mortality assumptions, we derive a variational inequality that governs the ruin probability and optimal asset allocation. We explore the qualitative properties of the ruin robability and optimal strategy, present a numerical method for their estimation, and examine their sensitivity to changes in model parameters for specific examples. We then present an easy-to-implement allocation rule and demonstrate via simulation that it yields nearly optimal ruin probability, even under discrete portfolio rebalancing.     

The implementation of special attributes of CEO compensation contracts around M&A transactions

This study investigates how the implementation of special attributes of CEO compensation contracts is determined by both the acquisition and the acquirer features for a set of M&A deals undertaken by Canadian acquiring firms. Our findings reveal that when agency problems are higher, manifested by larger control premiums and poor firm performance, boards of directors tend to implement stronger mechanisms of incentive alignment around M&A transactions. Relying on multiple interdisciplinary logics that are activated to explain directors' ability to effectively perform their monitoring function, we show that boards are reactive rather than proactive in dealing with agency problems. Data are further interpreted in light of the unique aspects of the Canadian institutional context. Based on asymmetric risk properties of two different groups of executive compensation modes examined in this study, testing the substitution effects between alternative governance mechanisms is proposed as an interesting avenue for future research.
