Financial Integration and EMU’s External Imbalances in a Two-Country OLG Model

The pronounced increase in external imbalances in the European Economic and Monetary Union (EMU) during the years running up to 2008 is traditionally explained by financial integration through the common currency. This paper examines in a one-good, two-country overlapping generations’ model, with production, capital accumulation and public debt, the effects of financial integration on the net foreign asset positions of initially low-interest and high-interest rate EMU countries. We find that a lower savings rate and government expenditure quota, together with a higher capital production share in the latter can in fact be transformed into the observed external imbalances when interest rates converge.     

Reorganizing School Lunch for a More Just and Sustainable Food System in the US

Public school lunch programs in the United States are contested political terrains shaped by government agencies, civil society activists, and agri-food companies. The particular organization of these programs has consequences for public health, social justice, and ecological sustainability. This contribution draws on political economy, critical food studies, and feminist economics to analyze the US National School Lunch Program, one of the world's oldest and largest government-sponsored school lunch programs. It makes visible the social and environmental costs of the “heat-and-serve” economy, where widely used metrics consider only the speed and volume of service as productive work. This study demonstrates that such a narrow understanding of the labor of lunch devalues care and undercuts the potential for school food provisioning to promote ecological and feminist goals. Further, it proposes a “high road” alternative and outlines an agenda for reorganizing school food provisioning to maximize care in all its dimensions.     

The political economy of state-level adoption of natural resource damage programs

U.S. states can implement programs to pursue damage recovery when firms cause natural resource damages (NRDs). We present new empirical evidence that such programs have effectively reduced oil spills in states that adopt them. However, only 34 states had implemented such programs by 2003. We analyze data on 50 states and the District of Columbia from 1980 to 2003 to ascertain the likely determinants of NRD program adoption. We find that states with many environmental accidents adopt programs more rapidly, while income and interest-group pressure have no significant impact on the process. While non-adopting states might benefit from such programs, at least NRD programs are being adopted most rapidly where they can do the most good.      

The effect of customers' emotional responses to service failures on their recovery effort evaluations and satisfaction judgments

This study examines the role of customer emotions in the context of service failure and recovery encounters. It investigates how customers' emotional responses to service failures influence their satisfaction judgments after accounting for cognitive antecedents of satisfaction. The study also considers how customers' emotional responses to service failures influence how they evaluate an organization's recovery efforts. The research is conducted by surveying customers about their satisfaction judgments in two service settings, restaurants and hotels. The results suggest that customers' emotional responses to service failures will influence their recovery effort evaluations and satisfaction judgments in some circumstances and that the effects of emotion vary across industry settings. This study identifies the types of efforts that are most effective in helping customers “recover” from the negative emotions caused by service failures. Amy K. Smith (Ph.D., University of Maryland) is currently an assistant professor of marketing at George Washington University.

Amended final-offer arbitration over an uncertain value: A comparison with CA and FOA

Arbitration is increasingly employed to resolve disputes. Two arbitration mechanisms, conventional arbitration (CA) and final-offer arbitration (FOA) are commonly utilized, but previous theoretical and empirical research has found that they are unsatisfactory. Several alternative mechanisms have been proposed, but ultimately laboratory research has found that they do not offer an improvement. An exception is amended final-offer arbitration (AFOA), which not only has desirable theoretical properties but also has been demonstrated to outperform FOA in the laboratory. This study provides a direct laboratory comparison of AFOA with CA. Also, by utilizing an environment with an uncertain payoff to one of the parties, this study tests the robustness of AFOA’s performance relative to FOA. The results indicate that AFOA does outperform FOA, but that AFOA is only weakly better than CA. JEL Classification C7, C9, J5, K4     

Superexponential long-term trends in information technology

Moore's Law has created a popular perception of exponential progress in information technology. But is the progress of IT really exponential? In this paper we examine long time series of data documenting progress in information technology gathered by [1]. We analyze six different historical trends of progress for several technologies grouped into the following three functional tasks: information storage, information transportation (bandwidth), and information transformation (speed of computation). Five of the six datasets extend back to the nineteenth century. We perform statistical analyses and show that in all six cases one can reject the exponential hypothesis at statistically significant levels. In contrast, one cannot reject the hypothesis of superexponential growth with decreasing doubling times. This raises questions about whether past trends in the improvement of information technology are sustainable.     

Are we operating effectively? A lean analysis of operating theatre changeovers

Hospital operating theatres are a critical but costly resource in healthcare processes. Their efficiency and utilisation impact upon hospital finances, clinical effectiveness and patient outcomes. Operations management techniques have now been applied widely to optimise flow. An important challenge is to balance the needs of process flexibility, efficiency and work standardisation with clinical requirements. This paper applies operations management methods to analyse elective orthopaedic surgery at five international hospitals to describe the issues that affect operating theatre productivity. It utilises an innovative method of video analysis to observe patient changeovers over 29 days of surgery and data is analysed to understand the causes of variability and waste. The findings suggest that processes which are standardised via operations management methodologies can improve productivity in a process that exhibits wide variation in practice. There are apparent trade-offs associated with efficiency and clinical concerns such infection control, that lead to different standard process archetypes being utilised. Recommendations for standardising patient changeovers are provided.
