Comment on "On the Uniqueness of Stable Marriage Matchings" [Economic Letters 69(1):1-8, 2000]

We prove with the help of a counterexample that Lemma 6 and Corollary 7 from Eeckhout [1] are incorrect.

International mortality modelling- an economic perspective

A recent literature has developed on modelling mortality in multiple populations together. The purpose of this paper is to suggest a reason why mortality in different populations may be related based on an economic literature on technology and knowledge diffusion.

Protecting the most vulnerable in an economic crisis: a participatory study of civil society organisations in the Republic of Ireland

This paper advances knowledge of how civil society organisations (CSOs) negotiate the shift from boom-time public expenditure to governmental austerity. The study focuses on the Republic of Ireland, where CSOs occupied an important role in providing a voice for ‘vulnerable’citizens in corporatism for over a decade. The global financial crisis and subsequent austerity measures caused the country’s model of corporatist-style ‘social partnership’ to collapse. The article connects CSOs’ adaptation to austerity measures when protecting the ‘people behind the cuts’ to broader questions about co-optation of civil society through state-led policymaking
institutions.

The Great Recession and the changing distribution of economic vulnerability by social class:The Irish case

Ireland provides an interesting case study of the distributional consequences of the Great Recession. To explore such effects we develop a measure of economic vulnerability based on a multidimensional risk profile for income poverty, material deprivation and economic stress. In the context of conflicting expectations of trends in social class differentials, we provide a comparison of pre and post-recession periods. Our analysis reveals a doubling of levels of economic vulnerability and a significant change in multidimensional profiles. Income poverty became less closely associated with material deprivation and economic stress and the degree of polarization between vulnerable and non-vulnerable classes was significantly reduced. Economic vulnerability is highly stratified by social class for both pre and post-recession periods. Focusing on absolute change, the main contrast is between the salariat and the non-agricultural self-employed and the remaining classes; providing some support for notions of polarization. In terms of relative change the higher salariat, the non-agricultural self-employed, the semi-unskilled manual and those who never worked gained relative to the remaining classes. This provides support the notion of ‘middle class squeeze’. The changing relationship between social class and household work intensity reflected a similar pattern. The impact of the latter on economic vulnerability declined sharply, while it came to play an increasing role in mediating the impact of membership of the non-agricultural middle classes. Responding to the political pressures likely to be associated with ‘middle class squeeze’ while sustaining the social welfare arrangements that have traditionally protected the economically vulnerable presents formidable challenges in terms of maintaining social cohesion and political legitimacy.

Linking response strategies adopted by construction firms during the 2007 economic recession to Porter’s generic strategies

The time period bridging the years 2007 to 2012 will be remembered as one characterised by dramatic changes in the Irish and UK construction industries. Construction companies witnessed unprecedented changes in the environment, namely the coincidence of a sharp economic downturn, the significant decline of public works, a reduction in lending, increased competition, and structural changes in the marketplace. Nevertheless, little has been documented on what response strategies construction companies adopt as a result of an economic recession. Based on four exploratory case studies, a taxonomy framework of the response strategies adopted by Irish and UK construction companies during the 2007 economic recession was developed relative to Porter’s (1980) generic strategies of cost leadership, differentiation, and focus. Porter’s model (1980) is a well known theoretical framework among business strategists and industrial economists worldwide. The analysis provides strong support for the adoption of cost leadership strategies as a means to surviving the 2007 economic recession. The case studies further suggest that cost control initiatives are one of the most important attributes in companies’ responses to the 2007 recession. The findings provide valuable assistance for construction contractors in developing effective strategies and thus reducing business failures during recessionary periods.

Crisis Cartels:Non-Economic Values, the Public Interest and Institutional Considerations

This paper considers the use of non-economic considerations in Article 101(3) analysis of industrial restructuring agreements, using the Commission's Decisions in Synthetic Fibres, Stichting Baksteen, and the recent UK Dairy Initiative as examples. I argue that contra to the Commission's recent economics-based approach; there is room for non-economic considerations to be taken into account within the framework of the European Treaties. The competition law issue is whether the provisions of Article 101(3) can save such agreements.
I further argue that there is legal room for non-economic considerations to be considered in evaluating these restructuring agreements, it is not clear who the appropriate arbiter of these considerations should be given the institutional limitations of courts (which have no democratic mandate), specialised competition agencies (which may be too technocratic in focus) and legislatures (which are susceptible to capture by rent-seeking interest groups).

Characterizing changes in the excitability of corticospinal projections to proximal muscles of the upper limb

Background: There has been an explosion of interest in methods of exogenous brain stimulation that induce changes in the excitability of human cerebral cortex. The expectation is that these methods may promote recovery of function following brain injury. To assess their effects on motor output, it is typical to assess the state of corticospinal projections from primary motor cortex to muscles of the hand, via electromyographic responses to transcranial magnetic stimulation. If a range of stimulation intensities is employed, the recruitment curves (RCs) obtained can, at least for intrinsic hand muscles, be fitted by a sigmoid function.

Objective/hypothesis: To establish whether sigmoid fits provide a reliable basis upon which to characterize the input–output properties of the corticospinal pathway for muscles proximal to the hand, and to assess as an alternative the area under the (recruitment) curve (AURC).

Methods: A comparison of the reliability of these measures, using RCs obtained for muscles that are frequently the targets of rehabilitation.

Results: The AURC is an extremely reliable measure of the state of corticospinal projections to hand and forearm muscles, which has both face and concurrent validity. Construct validity is demonstrated by detection of widely distributed (across muscles) changes in corticospinal excitability induced by paired associative stimulation (PAS).

Conclusion(s): The parameters derived from sigmoid fits are unlikely to provide an adequate means to assess the effectiveness of therapeutic regimes. The AURC can be employed to characterize corticospinal projections to a range of muscles, and gauge the efficacy of longitudinal interventions in clinical rehabilitation.

Towards groundwater security in coastal East Africa: initiating a regional research network and integrated hydrogeologic, climatic & socio-economic observatories in coastal aquifers of the Comoros Islands, Kenya and Tanzania

African coastal regions are expected to experience the highest rates of population growth in coming decades. Fresh groundwater resources in the coastal zone of East Africa (EA) are highly vulnerable to seawater intrusion. Increasing water demand is leading to unsustainable and ill-planned well drilling and abstraction. Wells supplying domestic, industrial and agricultural needs are or have become, in many areas, too saline for use. Climate change, including weather changes and sea level rise, is expected to exacerbate this problem. The multiplicity of physical, demographic and socio-economic driving factors makes this a very challenging issue for management. At present the state and probable evolution of coastal aquifers in EA are not well documented. The UPGro project 'Towards groundwater security in coastal East Africa' brings together teams from Kenya, Tanzania, Comoros Islands and Europe to address this knowledge gap. An integrative multidisciplinary approach, combining the expertise of hydrogeologists, hydrologists and social scientists, is investigating selected sites along the coastal zone in each country. Hydrogeologic observatories have been established in different geologic and climatic settings representative of the coastal EA region, where focussed research will identify the current status of groundwater and identify future threats based on projected demographic and climate change scenarios. Researchers are also engaging with end users as well as local community and stakeholder groups in each area in order to understanding the issues most affecting the communities and searching sustainable strategies for addressing these.
