The paper analyses the dynamics of some duopoly output games involving the Cournot, Market-Share and Nichol strategies. The model assumes linear price and cost functions and supposes that outputs are adjusted instantaneously at discrete time intervals. For all games considered, equilibrium is either reached after a finite number of moves or a stable approach to equilibrium occurs as t → ∞. In fact, apart from a few uninteresting cases, arising from the oversimplified form of the Market-Share strategy, all equilibrium points lie on specified parts of the firms' Cournot loci. 相似文献

ABSTRACTDespite the truism that less is known about the deep-sea than outer space, deep-sea mining (DSM) is being promoted as the next frontier of resource extraction. In 2019, Nautilus Minerals hopes to become the world’s first company to mine the deep seabed in the waters off Papua New Guinea (PNG). DSM thus stands at the threshold of becoming a matter of politics; it has provoked a wide range of geopolitical imaginaries variously relating to ‘resource security’ and ‘progress’, on the one hand, and environmental disaster and precaution on the other. However, these accounts do little to address the specific ‘nature’ of the deep-sea, seabed and their extreme location and materialities, and are instead framed by classic geopolitical concerns with interstate relations. Against this background and illustrated by examples centred on PNG, this paper argues that future engagements with the geopolitics of DSM are more accurately conceptualised by an engagement with time as well as three dimensional space. This includes the multiple spatial and temporal registers through which both the geology and ecologies of seabed and seawater operate. By highlighting the importance of resource temporalities, it suggests that the geopolitics of both DSM and extraction in extreme places more generally is not only spatially complex, it is also a matter of time. 相似文献

One particularly vexing puzzle for economists and policymakers over the past several decades concerns the empirical significance of the theoretically predicted pollution haven hypothesis. While neoclassical theory and conventional wisdom both surmise that local economies will suffer deleterious effects from stricter environmental regulations, empirical studies have largely failed to validate such claims. This study utilizes the method of matching to show that the impact of stricter regulation is heterogeneous spatially, varying systematically based on location-specific attributes. Previous studies that assume a homogenous response may therefore inadvertently mask the overall impact of more stringent regulations by pooling unaffected and affected regions.JEL Classification: Q25, Q28, H00, L51, R1The authors wish to thank to Michael Crew, Anthony Heyes, an anonymous referee, Werner Antweiler, Randy Becker, Wayne Gray, Shelby Gerking, Michael Greenstone, Vern Henderson, and Arik Levinson.

This paper examines the influence of economic integration—widening of the trading area—on economic development and the demographic transition. Economies produce with different technologies depending on their scale. Greater integration between regions (greater extensive scale) is instrumental in changing rates of return, which generates an industrial revolution and provokes changes in child bearing behavior. The demographic transition follows from the mortality response to income and birth response to greater scale. The model is calibrated and simulated using historical data from Europe. Historical evidence is cited to support the idea that integration precedes the dramatic rise in economic growth rates. 相似文献

Immigration and the Trade of Provinces 总被引:7,自引:0,他引:7
A link between immigration, imports, and exports has been found by a number of papers that have used the gravity equation to analyze bilateral trade patterns. We discuss what this research implies about the mechanisms through which immigrants expand trade and identify strengths and weakness of the various approaches. This paper also contributes to this literature by estimating immigrant effects for Canada using cross‐province variation in international trade and immigration patterns. We derive an alternative functional form capturing the relationship between immigration and trade based on the proposition that immigrants use their connections and superior 'market intelligence' to exploit trade opportunities that non‐immigrants do not access. We find that the average new immigrant expands exports to his/her native country by $312 and expands imports by $944. 相似文献

Abstract. Programs that defer taxes on savings (e.g., RRSPs or 401(k)s) are supposed to move income tax systems closer to the more efficient consumption tax. Whether or not RRSPs move income tax systems away from or closer to a consumption tax depends on whether or not interest on debts incurred to make RRSP contributions is deductible for income tax purposes. If people optimize as assumed in simple life‐cycle models, then it may be that governments can convert a non‐linear income tax system to a proportional consumption tax system. I argue this is plausible for some Canadian households. JEL classification: H21, H24 相似文献

It has often been suggested that National Insurance contributions and income taxation should be integrated in Britain, although the implications for the appropriate tax rates have not usually been examined in any detail. The complexity of the British National Insurance system means that the implications are not immediately clear. This paper examines the changes in tax rates which would be required to maintain total revenue at a constant level, and the tax rates required to support a minimum level of post-transfer income. 相似文献

This paper models the London stock markets response to the 1994 Periodic Review of prices in the English and Welsh water industry using both GARCH and stochastic volatility models. The results indicate that a significant reduction in the volatility of share prices for eight of the ten water and sewerage companies followed the announcement of revised industry price-caps. Investor expectations adjusted rapidly, reflecting confidence in the credibility and political sustainability of the settlement. 相似文献

This paper examines take–up rates in a model in which there is a fixed non–refundable cost of applying for benefits. The model involves a joint decision regarding both labour supply and the take–up of the benefit. There is a single means–tested benefit involving a 'taper rate' at which benefits are withdrawn as earnings increase. It is found that take–up increases as the level of the taper rate increases, and the value of benefits increases. The achievement of 100% take–up is associated with labour supply responses whereby there are few, if any, individuals who are both working and eligible for benefits. The results have implications for the effects of lowering the taper rate on the costs and effective targeting of benefits. 相似文献
