The Recognition of Wifely Labour by Welfare States

This article is concerned with questions about the amount of support given by welfare states towards the maintenance of a wife engaged in housework and child care. It compares the value of the support supplied by the tax/benefit packages of 15 countries. The article defines support for wifely labour as the difference between the net disposable income of a single person and a couple with the same earnings. In analysing the data, three models are used: the “traditional” model where the wife is economically dependent on her husband; the “modern” model where the wife remains outside the labour market while she has young children; and the “dual breadwinner” model where the mother of young children is in full- or part-time employment. Much of the analysis is concerned with patterns of social policy in which support for wives is associated with support for children. While the evidence shows that welfare states do provide support to wives, both with and without young children and engaged in paid as well as unpaid work, the levels of support vary greatly between welfare states. The variations are not associated with the generally discussed categorizations of welfare state types.     

Testing for Nonlinear Dependence in Inventory Data

This paper describes the properties of nonlinear dynamical systems in demand data and assesses the implications for inventory management. A test from Brock, Dechert, and Scheinkman (BDS) [6] for detecting nonlinearities is presented. This test assists inventory managers with two issues. First, it can be used to detect departures from the independence and stationarity assumptions of particular inventory models, thereby identifying the need for more suitable models. Second, the BDS test can determine whether forecasting model improvements are possible, and can measure improvements in the forecasting model process. The corresponding reductions in forecast errors improve inventory management and lead to reduced inventory costs. Using actual weekly demand for oil filters, this paper demonstrates the use of the BDS test and the effects of nonlinearities in demand data on inventory model performance.     

The influence of three genes on whether adolescents use contraception, USA 1994-2002

In a further contribution to recent investigations of the relevance of genetic processes for demographic outcomes, we investigate genetic associations with whether adolescents use contraception. Using data from the National Longitudinal Study of Adolescent Health, we find that variants in the dopamine transporter gene DAT1, the dopamine receptor gene DRD2, and the monoamine oxidase gene MAOA are associated with unprotected sexual intercourse. Consistent with previous analyses of these data, the genotypes DRD2*A1/A2, DRD2*A2/A2, DAT1*9R/10R, and MAOA*2R/ are associated with higher odds of unprotected sexual intercourse than other genotypes at these loci. The DRD2 associations apply to both men and women, whereas the other associations apply to women only. These results are robust to controls for population stratification by continental ancestry, do not vary by contraceptive type, and are consistent with previous research showing that these genetic variants are associated with higher rates of impulsivity.     

Common Threats and Managing Reputation in Executive Search Firms

A free video abstract to accompany this article can be found online at: https://www.youtube.com/watch?v=IziwDorbeGU This paper provides important insights into how executive search firms can successfully manage their reputations to overcome major threats to their organizations. The paper focuses on three threats faced by executive search firms: the global financial crisis; questions around the sector's professional status; and the proliferation of social media for recruitment. Our data show that there was not a single coherent response from firms, but a piecemeal approach that focused on three forms of reputation management. First, diversifying service offerings; second, highlighting their symbolic capital; and third, connecting their firms to clients and candidates through partners. Building on our data and the theoretical literature, we provide a framework for understanding how professional service firms can manage their reputations in response to common threats, based on three categories from the English idiom ‘keep up with the Joneses’. First, moving away from the Joneses; second, fencing out the Joneses; third, networking more than the Joneses. We provide theoretical and practical insights around how organizations can manage their reputations in response to threats which are common across sectors.

Modeling the welfare impacts of agricultural policies in developing countries

This paper presents a new model incorporating features of developing country agriculture likely to shape the welfare outcomes of alternative agricultural policies. The model features heterogeneous households linked through markets in a rural economy-wide structure, with endogenous market participation for farmers facing transactions costs. We use it to simulate the impacts on rural welfare of market price supports, production subsidies, input subsidies, and the removal of transaction costs. Applications to six countries demonstrate the diversity of potential impacts, exhibit some systemic differences compared with impacts in developed countries, and identify specific circumstances under which market interventions may be only slightly less efficient than direct payments at transferring incomes to rural households.
