The local stability of an open-loop Nash equilibrium in a finite horizon differential game

We propose a finite time differential game as a model for some economic processes and derive conditions for the Nash equilibrium solution to be locally asymptotically stable. We adopt the traditional ‘Cournot-reaction function’ notion of stability, which in our (continuous time) model becomes a function-to-function, or trajectory-to-trajectory, mapping. The conditions for stability seem to make economic sense. The equilibrium is less stable if the interaction terms in each period are large, if the game has a long duration, and if the discount rate is small.     

Insuring Eggs in Baskets: Should the Government Insure Individual Risks?

The vast majority of crop and revenue insurance policies sold in North America are single‐crop policies that insure against low yields or low revenues for each crop grown on a particular farm. This practice of insuring one crop at a time runs counter to the traditional risk management practice of diversifying across several enterprises to avoid putting all of one's eggs in a single basket. This paper examines the construction of a whole‐farm crop revenue insurance program to include livestock price risk. The results show that at coverage levels of 95% or lower, the fair insurance premiums for this product on a well‐diversified Iowa farm are far lower than the fair premiums for the corn crop alone on the same farm. The calculation of premium rates for the whole‐farm insurance product is derived from a method for imposing correlations first proposed by Iman and Conover in 1982. The potential income transfer from crop insurance is also examined. We find that the income transfer due to the subsidization of single‐commodity policies is greater than the total premium for whole‐farm policies. La grande majorité de polices d'assurances de récolte et de revenu agricole vendues en Amérique du nord sont des polices de récolte individuelle qui assurent contre des rendements faibles ou bas revenu pour chaque récolte cultivée par une ferme particulière. Cette pratique de n'assurer une récolte à la fois fonctionne à l'opposé de la pratique traditionnelle de gestion des risques par la diversification à travers plusieurs entreprises pour éviter de mettre tous ses oeufs dans un seul panier. Cet article examine la construction d'un programme d'assurance agricole pour l'ensemble des récoltes produites par une ferme y compris le bétail évalue le risque. Les résultats montrent qu'aux niveaux d'assurance plus petits ou égaux à 95 pourcents, les primes d'assurance justes pour ce type de police pour une ferme bien diversifiée de l'Iowa sont bien inférieures aux primes justes pour une police de simple couvrant le maïs et ce pour la même ferme. Le calcul des taux de prime pour une police couvrant l'ensemble des récoltes est dérivé d'une méthode pour imposer des corrélations originalement proposée par Iman et Conover en 1982. Le transfert potentiel de revenu à partir de l'assurance de récolte agricole est également examiné. Nous trouvons que le transfert de revenu dûà la subvention des polices pour récolte singulière est plus grand que la prime entière pour une police couvrant l'ensemble des récoltes.     

Workforce shortages are a global issue

A consortium of international organizations convened a first-ever Global Health Care Workforce Conference to discuss the worldwide shortages of health care workers and the migration patterns of health care workers from developing nations to the first world. Over 300 participants from 47 countries, including one-third from developing countries, discussed a variety of critical issues ranging from global immigration, recruitment, economics, to partnerships. Results, recommendations, and actionable items generated from the conference, as well as ways to put these ideas into practice, will be critical for sustaining and improving world health and the plight and numbers of health care providers.     

Portugal’s banking and financial crises: unexpected consequences of monetary integration?

Portugal’s current financial crisis might be related to a banking crisis resulting from joining the Euro. The new-currency eliminated the exchange rate risk, but not the credit or liquidity risks within the Euroarea. However, Portuguese banks acted as if all of these risks had disappeared. They began pumping money in Portugal, by borrowing intensively in Euros abroad at low interest rates. The ensuing liquidity generated a capital-flow bonanza boom that culminated in a bust phase. Private and sovereign debt dramatically increased, which further soared when the government rescued banks. Portugal was then compelled to take extreme measures to address extraordinary debt-levels.     

Understanding the town centre customer experience (TCCE)

This research enhances the understanding of consumer behaviour and customer experience in the context of town centres. First, it defines town centre customer experience (TCCE) as a multifaceted journey that combines interactions with a diverse range of public and private organisations, including retailers and social and community elements; this results in a unique experience co-created with the consumer across a series of functional and experiential touchpoints. Second, combining qualitative and quantitative insights, this research reveals a series of specific functional and experiential TCCE touchpoints, which underpin the consumer internal response (motivation to visit) and outward behaviour (desire to stay and revisit intentions) in the town centre. In addition to enhancing town centre and customer experience knowledge, these findings offer important new insights to those managing town centres and seeking to retain customer loyalty in the high street. Above all, these findings can help identify the touchpoints that need to be reinforced and/or improved to differentiate a town from its competing centres and to create tailored marketing strategies. Taken together, such initiatives have the potential to positively impact the revitalisation of the high street and the town centre economy.     

R&D Subsidies and Foreign Direct Investment

We devise a model in which domestic firms do applied R&D, which can be subsidized by the government, and foreign firms with superior technology can enter in the domestic market. Foreign Direct Investment can act as a substitute of subsidies to improve domestic R&D, the share of domestic leading firms and consumption. Relatively closed economies may benefit from R&D subsidization while relatively open economies may not. For relatively low growth of the technological frontier, it is optimal to subsidize R&D and close the economy to foreign investment but the opposite happens for relatively high growth. Numerical simulations show the economy dynamics after policy experiments.
