Human resource management implications of dual-career couples

The dual-career couple is a contemporary phenomenon in Western industrialized nations. This Australian qualitative investigation explored the organizational issues associated with dual-career couples from the perspective of both dual-carrer couple members and their employing organizations. Overall, it was found that organizational responsiveness to dual-career issues was limited, and consequently dual-carrer couples themselves were forced to make most of the necessary accommodations. Human resource management implications of the dual-career couple are discussed. To date, however, such implications have been largely ignored by organizations. The findings of this study suggest that the failure of organizations to respond to dual-career issues results in costs, not only to the couple, but also to their employing organizations. Predictions for continued growth of the dual-career phenomenon mean that an organization s willingness to address dual-career issues may become an important element in achieving and retaining competitive advantage.

Individual versus companion visitors' willingness-to-pay for the theater tickets: The case of Perm opera

Business-like approaches are applied more and more widely in nonprofit organization contexts, and theaters are no exception. Revenue generation, customer segmentation, and personalized marketing are becoming the key managerial concerns. Our study focuses on two relevant aspects of theater attendees' behavior. We examine visitors' willingness-to-pay (WTP) for theater seats (to derive revenue drivers), and its difference between two segments – single and couple visitors (to uncover the social motivation effect). These aspects taken together have never been previously studied in the nonprofit marketing context. We model WTP using the actual purchase data from Perm Opera and Ballet Theatre in Russia. Unlike most marketing studies which use stated preference for WTP evaluation, we employ the revealed preference approach. The results verify that single and couple visitors may be treated as separate segments, allowing for personalized promotion and other marketing decisions.     

On the convergence to the Cournot equilibrium in a productive asset oligopoly

We derive a feedback equilibrium of a dynamic Cournot game where production requires exploitation of a renewable asset. As in the classical Cournot model, quantity-setting firms compete in the same market for a given homogeneous good. We show that, when the asset stock grows sufficiently fast, the unique globally asymptotically stable steady state of the dynamic Cournot game corresponds to the static Cournot solution. Initial differences between firms’ production rates due to asymmetric allocations of asset stocks tend to disappear over time. When instead the asset stock grows slowly, the system does not converge to any stationary point. We also show that, within the class of linear feedback equilibrium strategies, besides the couple of strategies that stabilizes the states for every possible initial conditions, there exists another couple which is more efficient, in that it leads to higher stationary equilibrium profits for both firms, closer to the collusive outcome. Finally, we show that, as the discount rate approaches zero, there exist multiple linear feedback equilibrium strategies that induce a price trajectory that converges asymptotically to a price which is above the static Cournot equilibrium price.     

Local block bootstrap inference for trending time series

Resampling for stationary sequences has been well studied in the last couple of decades. In the paper at hand, we focus on nonstationary time series data where the nonstationarity is due to a slowly-changing deterministic trend. We show that the local block bootstrap methodology is appropriate for inference under this locally stationary setting without the need of detrending the data. We prove the asymptotic consistency of the local block bootstrap in the smooth trend model, and complement the theoretical results by a finite-sample simulation.     

Family Formation and the Divisions of Labour in Belgian Couple Households

In this chapter the authors describe how a quantitative analysis resulted in a proposal for a qualitative research. The aim of the quantitative research was to analyse the impact of family formation on the division of labour in couple households, based on data from the Panel Study on Belgian Households.In a first step a typology was made based upon data of 1224 Belgian couple households (1995). The second step consisted of a longitudinal analysis for the period between 1992 and 1995. The analysis of the impact of birth on the division of labour gave evidence of the revocability of equal patterns of division of labour.Based on these findings the authors concluded that the classic concept of emancipation does not allow us to understand the empirical phenomena. Hence, the authors proposed a new (qualitative) investigation aimed at clarification and empirical validation of different contents of the concept of emancipation.     

Salvation Army utilizes intensive personal cultivation campaign

The cultivation program goal was to increase the cash income through developing good personal rapport with donors. It was decided that no one would be directly asked to give more money during the first couple of years until that rapport was established.     

Dual-career couples during international relocation: The trailing spouse

Expatriate relocation is a complex process which is influenced by a variety of issues. One issue, the dual-career couple, increases the likelihood of dissatisfaction and failure of the foreign assignment. The trailing spouse plays a critical role in the amount of stress/conflict experienced by the expatriate and she/he is key to increasing the success rate of expatriate managers. This research reports on a survey of 258 dual-career couples and their concerns with: (1) willingness to relocate; (2) unique adjustment issues; (3) stress/conflict generating situations; and (4) the type/level of support provided by the expatriate managers' MNCs.     

Why Have Housing Transactions Been So Weak?

Activity in the UK housing market has been surprisingly weak over the last couple of years, particularly given the very cheap, fixed-rate mortgage deals that are now available. In this article, Geoff Meen asks why the number of transactions has been so low and looks at future prospects for the housing market.     

A SURVEY OF THE EFFECTS OF THE MINIMUM WAGE ON PRICES

Abstract.  It is well established in the literature that minimum wage increases compress the wage distribution. Firms respond to these higher labour costs by reducing employment, reducing profits, or raising prices. While there are hundreds of studies on the employment effect of the minimum wage, there are merely a handful of studies on its profit effects, and only a couple of dozen studies on its price effects. Furthermore, a comprehensive survey on minimum wage price effects is not available in the literature. Given the policy relevance of this neglected issue, in this paper we summarize and critically compare the available evidence on the effects of minimum wages on prices.

Is the first UK rate hike imminent?

• The events of the past couple of months have led us to push out our call for the first UK rate hike from February 2016 to May 2016. The financial market turmoil of late summer, increasingly dovish commentary from the MPC, the enduring strength of sterling and the likelihood of lower inflation over the next six months are all factors which point to the first rate hike coming later.
• This is a modal forecast which is consistent with our baseline forecast playing out. But the escalating downside risks would imply a mean forecast which shows the first rate hike coming even later still and the subsequent path of monetary tightening being shallower. This explains why the expectations of financial markets may appear to be more bearish than our own.

     

Su Una Estensione Bidimensionale del Teorema di Scomposizione di Peccati

Facendo ricorso all’introduzione di una opportuna condizione di sincronia fra due coppie di tassi (i, j), esterna, e (i*, j*), interna, si dimostra che condizione necessaria e sufficiente per la validità finanzíaria di una estensione hidimensionale del teorema di scomposizione di Peccati è che le due coppie (i, j) e (i*, j*) soddisfino tale proprietà di sincronia.

A two-dimensional extension of peccati’s decomposition theorem

Summary This paper keeps as starting poing the Peccati’s decomposition of the d.c.f. of an enterpreneural project seen as a present value of single-period results, recently given by the author in an unidimensional framework. The goal of the paper is twofold: the first is to provide a bidimensional extension of the decomposition in order to keep account of mixed projects, that is projects that according to any internal couple (i*, j*) reveal alternance of investment and respectively collection periods. A straightforward extension is given on the basis of a simple analogic argument. But a more careful evaluation of the problem suggests that if we require that the decomposition be meaningful from a financial point of view. things are no more simple either in one or in two dimensions. To solve the problem we introduce a proper synchrony condition: precisely, the pair of couples (i, j) and (i*, j*) are said to satisfy the synchrony condition if and only if the sequences of the signs of the partial balancesM _t (i, j) andM _t (i*, j*) are the same. After that we are able to show that, with reference to a couple (i, j) of external rates, a bidimensional decomposition centered on an internal couple (i*, j*) is meaningful if and only if the pair (i, j) and (i*, j*) satisfy the synchrony condition. Formally, the result comes as a nice byproduct of a rule on the factorization of particular bivariate polynomials recently given by Stucchi. In particular going back to a one-dimensional world, it turns out that for pure investment (Soper) projects the synchrony condition works as a condition of applicability of the Peccati’s decomposition.

CHILDREN, FAMILIES AND THE FAILURE OF UK ANTI-POVERTY POLICY

Relative child poverty is often associated with single parenthood. In fact, children of single parents have always constituted a minority of relatively poor children in the UK. However, in the last decade the Blair government has pursued an anti-poverty strategy targeted at single-parent families with the result that children in couple families have become relatively poorer and powerful disincentives have been created that discourage people from taking the most viable routes out of poverty.     

All-engaging Systems

A multiple product system is represented by a couple of matrices that describe the inputs and outputs of every process. Under specific assumptions on the matrices, the economy behaves like a single-product system, at least locally. It is called ‘all-engaging’ if the economy is indecomposable and ‘all-productive’ otherwise. An exhaustive study of the mathematical and economic properties is proposed. This approach is useful to formalize the notion of sector.     

A planning model for regional systems of CT scanners.

For the last couple of years the number of CT scanners has increased considerably in the Federal Republic of Germany. This development has led to regional disparities in the provision of CT scanner installations. For the purpose of evaluating additional locations for CT scanners a planning model is proposed. The model contains two planning options: the number of CT scanners and the regional distribution of scanner locations. It allows one to calculate overall operation costs and transportation costs, as well as additional criteria relevant to decisions about regional systems of CT scanners. The model has been applied to the northeast of Baden-Württemberg. One of the interesting findings is that an increase in the number of CT scanners may result in lower total costs for a regional system of CT scanners.     

Bayesian forecasting and portfolio decisions using dynamic dependent sparse factor models

We extend the recently introduced latent threshold dynamic models to include dependencies among the dynamic latent factors which underlie multivariate volatility. With an ability to induce time-varying sparsity in factor loadings, these models now also allow time-varying correlations among factors, which may be exploited in order to improve volatility forecasts. We couple multi-period, out-of-sample forecasting with portfolio analysis using standard and novel benchmark neutral portfolios. Detailed studies of stock index and FX time series include: multi-period, out-of-sample forecasting, statistical model comparisons, and portfolio performance testing using raw returns, risk-adjusted returns and portfolio volatility. We find uniform improvements on all measures relative to standard dynamic factor models. This is due to the parsimony of latent threshold models and their ability to exploit between-factor correlations so as to improve the characterization and prediction of volatility. These advances will be of interest to financial analysts, investors and practitioners, as well as to modeling researchers.

Combining homogeneous groups of preclassified observations with application to international trade

This article proposes three methods for merging homogeneous clusters of observations that are grouped according to a pre‐existing (known) classification. This clusterwise regression problem is at the very least compelling in analyzing international trade data, where transaction prices can be grouped according to the corresponding origin–destination combination. A proper merging of these prices could simplify the analysis of the market without affecting the representativeness of the data and highlight commercial anomalies that may hide frauds. The three algorithms proposed are based on an iterative application of the F‐test and have the advantage of being extremely flexible, as they do not require to predetermine the number of final clusters, and their output depends only on a tuning parameter. Monte Carlo results show very good performances of all the procedures, whereas the application to a couple of empirical data sets proves the practical utility of the methods proposed for reducing the dimension of the market and isolating suspicious commercial behaviors.
