Conservative Welfare Reform Proposals and The Reality of Subemployment

This article analyzes and critiques conservative welfare proposals and their assumptions. The concept of subemployment is introduced along with relevant data to identify the nature of the job problem in the U.S. since the early 1970s. Particular emphasis is placed upon the magnitude of employment difficulties during the 1980s. The article concludes that without a major job creation component, conservative welfare reforms intensify rather than ameliorate the subsistence living conditions of the poor

The environmental security debate and its significance for climate change

Policymakers, military strategists and academics all increasingly hail climate change as a security issue. This article revisits the (comparatively) long-standing “environmental security debate” and asks what lessons that earlier debate holds for the push towards making climate change a security issue. Two important claims are made. First, the emerging climate security debate is in many ways a re-run of the earlier dispute. It features many of the same proponents and many of the same disagreements. These disagreements concern, amongst other things, the nature of the threat, the referent object of security and the appropriate policy responses. Second, given its many different interpretations, from an environmentalist perspective, securitisation of the climate is not necessarily a positive development

Security: Collective good or commodity?

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2008 Sage.The state monopoly on the legitimate use of violence in Europe and North America has been central to the development of security as a collective good. Not only has it institutionalized the state as the prime national and international security provider, it has helped to reduce the threat from other actors by either prohibiting or limiting their use of violence. The recent growth of the private security industry appears to undermine this view. Not only are private security firms proliferating at the national level; private military companies are also taking over an increasing range of military functions in both national defence and international interventions. This article seeks to provide an examination of the theoretical and practical implications of the shift from states to markets in the provision of security. Specifically, it discusses how the conceptualization of security as a commodity rather than a collective good affects the meaning and implementation of security in Western democracies.ESR

Cost-effective external interference for promoting the evolution of cooperation.

The problem of promoting the evolution of cooperative behaviour within populations of self-regarding individuals has been intensively investigated across diverse fields of behavioural, social and computational sciences. In most studies, cooperation is assumed to emerge from the combined actions of participating individuals within the populations, without taking into account the possibility of external interference and how it can be performed in a cost-efficient way. Here, we bridge this gap by studying a cost-efficient interference model based on evolutionary game theory, where an exogenous decision-maker aims to ensure high levels of cooperation from a population of individuals playing the one-shot Prisoner's Dilemma, at a minimal cost. We derive analytical conditions for which an interference scheme or strategy can guarantee a given level of cooperation while at the same time minimising the total cost of investment (for rewarding cooperative behaviours), and show that the results are highly sensitive to the intensity of selection by interference. Interestingly, we show that a simple class of interference that makes investment decisions based on the population composition can lead to significantly more cost-efficient outcomes than standard institutional incentive strategies, especially in the case of weak selection.</p

It's Capacity, Stupid: International Assistance and National Implementation

Issues associated with state inability (or incapacity) to meet international commitments-and how to build such capacity-are now ubiquitous in the theorizing, practice and research agendas of international environmental cooperation. Yet "capacity" and "capacity building" remain under-specified at the conceptual level. They are neglected areas of empirical research, and generally unreflective in practice. International and national level policy-makers are struggling with questions about how best to enhance state, local and NGO capacities to meet international commitments. To illustrate the need for more conceptual attention and empirical research around issues of public sector capacity, the article presents a multi-dimensional understanding of public sector capacity and highlights programs that appear to be successfully building capacity in recipient countries and programs that seem to be unsuccessful. The article draws examples from multilateral assistance programs within regional marine pollution control regimes and from bilateral assistance programs associated with cleaning up radioactive legacies of the Cold War in post-communist states.
