Recent trends and structural breaks in the US and EU15 labour productivity growth

This article examines shifts in labour productivity growth in the US and in Europe between 1970 and 2007 based on econometric tests of structural breaks. Additionally, it makes use of time-series-based projections of labour productivity growth up to 2009 in order to detect breaks depending on confidence intervals of the projections. The identification of structural breaks in the US labour productivity growth is far from obvious. A statistically significant break is found in the late 1990s only if at least the 97.5th percentile of forecasts materializes in the future, which means that despite a clear pick up in productivity growth in the second half of the 1990s, the size of the hump is not large enough compared with past variations to make this change a statistically significant break. However, a significant break point is detected in the mid-1990s for the difference in labour productivity growth between the US and the EU15, even when controlling for the convergence of Europe towards the US productivity levels that has contributed to higher European performance in the early catch up phase. Finally, within Europe, the accumulation of Information and Communication Technology (ICT) capital seems to be related to differences in the shifts in structural labour productivity growth across countries.     

Market Failures and the Rationale for National Parks

America's national park system is widely admired, but the economic rationale for national parks is not compelling. The author discusses how market failures of various kinds can, in principle, be used to justify national parks. The best rationale for national parks is based on existence or nonuse values rather than on their recreational aspects. The author also shows that more evidence, especially regarding the costs of providing and operating parks and the magnitude of nonuse values, needs to be gathered before the case for national parks becomes compelling. Although this evidence will be difficult to obtain, it is hard to give an economic rationale for national parks without it.     

On Intertemporal Subsidy-Free Prices and Economic Depreciation: Constrained Market Pricing Revisited

The constrained market pricing approach to regulating monopolies maintains that prices should be subsidy-free, lying between the often expansive bounds of stand alone and incremental costs. For a simple two-good/two-period model of a monopolist subject to a zero profit constraint, it is shown that subsidy-free prices are those which rise to the amortized opportunity cost of the currently optimal asset configuration required to meet both current and future demand, providing—in some circumstances—justification for accelerated depreciation. Such intertemporal subsidy-free prices recognize that the stand alone cost of existing assets to current consumers depends on the value of those assets to future consumers. Hence, if a feasible resale price for the fixed costs of capacity exists within or between periods, then intertemporal stand alone costs and intertemporal incremental costs are driven to equality.     

Irish trade unions under social partnership: a Faustian bargain?

Since 1987 trade unions have been a key party to social partnership agreements in Ireland. Theoretical and empirical studies of corporatism point to positive outcomes for trade unions such as an increase in union density, ease of recognition, and increased employer support. However, apart from a modest increase in union membership numbers, none of these outcomes were realised. Union density levels have decreased significantly, union recognition is more problematic than ever, and employer opposition appears to have increased in scope and intensity. Decline in union density questions the capacity of unions to remain pivotal actors in the future. During the period of partnership union density in the private sector more than halved. It remains the paradox of partnership.     

Unbundling Ownership and Control

We study control contests under asymmetric information. Using a mechanism design approach, we fully characterize the optimal control contest mechanism. The optimal mechanism requires increasing the number of shares owned by the incumbent insider if he remains in control, while giving him a golden parachute that includes both shares and cash if he is deposed. The model underscores a novel explanation for the prevalence and persistence of the separation of ownership from control: efficiency in control contests is more easily achieved when ownership of cash flow rights is not concentrated in the hands of insiders.     

Cost-effectiveness of percutaneous patent foramen ovale closure as secondary stroke prevention

Objective: Compared to medical therapy alone, percutaneous closure of patent foramen ovale (PFO) further reduces risk of recurrent ischemic strokes in carefully selected young to middle-aged patients with a recent cryptogenic ischemic stroke. The objective of this study was to evaluate the cost-effectiveness of this therapy in the context of the United Kingdom (UK) healthcare system.

Methods: A Markov cohort model consisting of four health states (Stable after index stroke, Post-Minor Recurrent Stroke, Post-Moderate Recurrent Stroke, and Death) was developed to simulate the economic outcomes of device-based PFO closure compared to medical therapy. Recurrent stroke event rates were extracted from a randomized clinical trial (RESPECT) with a median of 5.9-year follow-up. Health utilities and costs were obtained from published sources. One-way and probabilistic sensitivity analyses (PSA) were performed to assess robustness. The model was discounted at 3.5% and reported in 2016 Pounds Sterling.

Results: Compared with medical therapy alone and using a willingness-to-pay (WTP) threshold of £20,000, PFO closure reached cost-effectiveness at 4.2 years. Cost-effectiveness ratios (ICERs) at 4, 10, and 20 years were ?20,951, ?6,887, and ?2,158, respectively. PFO closure was cost-effective for 89% of PSA iterations at year 10. Sensitivity analyses showed that the model was robust.

Conclusions: Considering the UK healthcare system perspective, percutaneous PFO closure in cryptogenic ischemic stroke patients is a cost-effective stroke prevention strategy compared to medical therapy alone. Its cost-effectiveness was driven by substantial reduction in recurrent strokes and patients’ improved health-related quality-of-life.     

Financial Sector Reforms in Developing Countries: The Indian Experience

This study is based on the premise that the success/failure of financial sector reforms depends heavily on country specific factors and makes an attempt to examine these factors in the Indian context. The financial sector reforms analysed in this paper include the deregulation of interest rates, increasing competition and foreign ownership, and the introduction of financial supervision. We argue that an economic rationale for a gradualist approach to financial reform is that it is stability enhancing. Furthermore, we suggest that India’s complex political economy has resulted in a gradual approach to reform, and this approach has been successful along the dimension of banking stability.     

Community-based programmes to promote use of bicycle helmets in children aged 0-14 years: a systematic review

Hospital-based research has shown that wearing a helmet reduces the risk of head injury in bicycle riders. These studies have provided the impetus for community-wide interventions to increase the numbers of cyclists who wear helmets; however, the effectiveness of such programmes is undetermined. This study employs extensive search strategies to review the scientific literature to establish the effectiveness of community-wide programmes to increase helmet use among cyclists. Thirteen community-wide intervention studies using substantive methodologies were located in 16 published papers. The community-wide interventions include mandating helmet wearing, education campaigns, distribution of free or subsidized helmets or, more frequently, combinations of all of these methods of influence. All studies reported success in influencing helmet wearing across communities. However, none of the studies reveals enough detail of the mix or techniques employed in the interventions to replicate the interventions. While it is encouraging that all of the studies showed positive results, the way forward for further implementation of helmet wearing is for adequate documentation of successful interventions.     

Reinsuring Agricultural Risk

This paper develops a basic economic model for evaluating the critical factors affecting crop insurer risks and for computing reinsurance premiums. The model shows how insurer risks and returns are determined by the individual yield risks of insureds, loading factors, administrative costs, buffer accounts and, importantly, the distribution of insureds across crop types and crop growing regions. Based on these factors, an approach toward computing actuarial reinsurance premiums is presented, with examples.
Nous présentons un modèle économique de base pour évaluer les facteurs critiques agissant sur les risques du fournisseur d'assurance-récolte et pour calculer les primes de réassurance. Le modéle montre dans quelle mesure les risques et les profits de l'assureur sont déterminés par les risques de rendement particuliers de l'as suré, les facteurs de charge, les frais d'administration, les fonds de tampons et, surtout, la répartition des assurés par type de récolte et par région de culture. À partir de ces éléments, une démarche de calcul des primes actuarielles de réassurance est présentée, exemples à l'appui.
