Discussion of dynamic programming and linear programming approaches to stochastic control and optimal stopping in continuous time

This paper seeks to highlight two approaches to the solution of stochastic control and optimal stopping problems in continuous time. Each approach transforms the stochastic problem into a deterministic problem. Dynamic programming is a well-established technique that obtains a partial/ordinary differential equation, variational or quasi-variational inequality depending on the type of problem; the solution provides the value of the problem as a function of the initial position (the value function). The other method recasts the problems as linear programs over a space of feasible measures. Both approaches use Dynkin’s formula in essential but different ways. The aim of this paper is to present the main ideas underlying these approaches with only passing attention paid to the important and necessary technical details.     

Beyond traditional paternalistic and developmental approaches to organizational change and human resource strategies

This paper assumes that a critical determinant of success in the repositioning of an organization's corporate and business strategies is the internal capability of the organization to implement change through an effective management process. To overcome entrenched interest groups, tender-minded, incremental approaches may be contrasted with the tough-minded strategic orientation of those who advocate radical change. The argument of this paper is that contingent rather than universalistic approaches are required. ‘Soft’ and ‘hard’ approaches are not irreconcilable but are rather parts of a broad set of contingent choices available to decision makers.     

Opportunism or strategic opportunity seeking? Three approaches to emerging country sourcing

The current interest in low-cost or emerging country sourcing (ECS) has inspired a multitude of empirical studies. These studies are based on varying methodological approaches and have come to somewhat different conclusions regarding the motivations for and outcomes of ECS. This paper argues that the overall approach to the new markets, especially the strategic network context surrounding each buyer-supplier relationship in the ECS setting, impacts on the prerequisites for success.The aim of the paper is to identify and discuss approaches to ECS. It begins with a review of recent empirical studies, scrutinising research interests and the approaches applied by the companies studied. It suggests and illustrates three broad categories of approaches: (1) the transactional approach focusing on individual sourcing in the emerging country, (2) the supply base approach focusing on establishing a set of supplier relationships in the emerging country, and (3) the network positioning approach in which both supplier and customer relationships are developed in the emerging country. The paper also discusses the three approaches as stages in an internationalisation process.The paper concludes that of the three strategic approaches the viability of two – the transactional approach and the supply base approach – can be questioned on several grounds, but that when seen as a process directed towards developing a network position in a new (emerging) market all three approaches make sense as different stages in a process moving towards achieving that goal. An explanation for the process of increasing commitment in emerging markets, relying on learning in interaction and on relational investments beginning with suppliers and continuing with customers, is also discussed.     

A comprehensive conceptual and bibliometric study of person-centered methodologies

Person-centered approaches, such as latent profile analysis (LPA) and qualitative comparative analysis (QCA), have gained in popularity in organizational scholarship because of their ability to provide insight into how interrelations between a group of conditions can lead to a particular outcome. Despite the growing acceptance of person-centered approaches in social science research, traditional variable-centered approaches continue to prevail, although their dominance is increasingly questioned. This paper offers in-depth analysis of the current state of QCA and LPA from both a conceptual and a bibliometric perspective. This study thus aims to contextualize the role of person-centered methodologies in organizational scholarship. This aim is important, given the significance of exploring novel approaches to advance knowledge in organizational research. This paper provides scholars with quantifiable and readily comparable information on the use of these emerging but promising methods in organizational studies. Ultimately, this scientific contribution sheds light on the current and prospective applications of person-centered methods in research. Moreover, it offers scholars who are considering applying these methods objective analysis of the scientific production in this area thus far.

     

An algebraic generalisation of some variants of simple correspondence analysis

For an analysis of the association between two categorical variables that are cross-classified to form a contingency table, graphical procedures have been central to this analysis. In particular, correspondence analysis has grown to be a popular method for obtaining such a summary and there is a great variety of different approaches that one may consider to perform. In this paper, we shall introduce a simple algebraic generalisation of some of the more common approaches to obtaining a graphical summary of association, where these approaches are akin to the correspondence analysis of a two-way contingency table. Specific cases of the generalised procedure include the classical and non-symmetrical correspondence plots and the symmetrical and isometric biplots.     

Measuring Cost Efficiency in European Banking: A Comparison of Frontier Techniques

This paper investigates the consistency of efficiency frontier methods on European banking samples. We measure the cost efficiency of banks from five European countries (France, Germany, Italy, Spain, Switzerland) with three approaches: stochastic frontier approach, distribution-free approach, and data envelopment analysis. We compare means, correlation coefficients, two public policy issues, and the correlation with standard measures of performance. In general, we conclude in favor of the lack of robustness between approaches, even if there are some similarities in particular between parametric approaches. We do, however, observe some correlation between all frontier approaches and standard measures of performance.

HOW TO MEASURE LABOUR MARKET EFFECTS OF IMMIGRATION: A REVIEW

Abstract.  This paper surveys available empirical evidence on labour market effects of immigration. Many different approaches have been used already to try to find out whether immigration hurts the labour market opportunities of natives. No doubt new approaches will follow in the future as globalization will keep the migration issue on the agenda. This literature review discusses the different approaches concentrating on both the methodology and the results. At the end, it tries to summarize available evidence.     

Modern Strategies for Time Series Regression

This paper discusses several modern approaches to regression analysis involving time series data where some of the predictor variables are also indexed by time. We discuss classical statistical approaches as well as methods that have been proposed recently in the machine learning literature. The approaches are compared and contrasted, and it will be seen that there are advantages and disadvantages to most currently available approaches. There is ample room for methodological developments in this area. The work is motivated by an application involving the prediction of water levels as a function of rainfall and other climate variables in an aquifer in eastern Australia.     

Incompatibility Between Hazard- and Logistic-Regression in Modeling Survival Data with Multiple Causes of Failure

This paper examines the relationship between outcomes from separate hazard modeling of two competing risks and those based on hazard-modeling of the overall risk combined with logistic-regression on the conditional probability of the risk of interest. The formulation presented in this paper generializes for continuous time models and allows for non-categorical covariates. Our analytical results show that the two approaches are incompatible because they address different issues. Such a straightforward explanation of the incompatibility between the two approaches is expected to prompt investigators to focus on identifying situations of when the issue addressed by each approach may be of substantive interest.     

Estimating the Income Elasticity of Demand for Housing: A Comparison of Traditional and Lorenz-Concentration Curve Methodologies

This paper provides a comparative analysis of traditional and Lorenz concentration curve (LC) approaches to estimating the income elasticity of demand for housing. Using data from the 1989 American Housing Survey, we compare LC results with those obtained from a traditional model in which tenure choice and housing demand are jointly determined, and which includes non-income determinants of demand. The comparison is intended to provide researchers with information concerning specific differences in empirical results obtained using the two approaches.     

Networks in family business: a multi-rational approach

Current research on networks in family businesses has approached the topic from a mono-rational perspective where the family, business and social networks are each considered in relative isolation. This paper argues that multi-rational approaches, which accept that the three groups of networks interact and overlap, offer a useful alternative perspective. In proposing the case for multiple rationalities as a framework within which family business networking can be viewed – and in putting forward an initial model – the paper allows the interaction of the different networks within the family business to be more fully acknowledged. Evidence from the literature is presented as a basis for further exploration using empirical approaches and it is emphasised that further and empirical approaches are required.     

Bayesian Variable Selection in Spatial Autoregressive Models

This paper compares the performance of Bayesian variable selection approaches for spatial autoregressive models. It presents two alternative approaches that can be implemented using Gibbs sampling methods in a straightforward way and which allow one to deal with the problem of model uncertainty in spatial autoregressive models in a flexible and computationally efficient way. A simulation study shows that the variable selection approaches tend to outperform existing Bayesian model averaging techniques in terms of both in-sample predictive performance and computational efficiency. The alternative approaches are compared in an empirical application using data on economic growth for European NUTS-2 regions.
