Individual bid functions display sensitivity to the strategic considerations inherent in first-price auctions. However, several formal models, including heterogeneous Nash equilibrium bidding models with constant relative risk aversion, perform quite poorly. 相似文献

This article evaluates the effects of budget consolidation on the Australian economy in the 1990s. As the economy recovered from the 1991–92 recession, the need to improve the fiscal balance to lift national saving became the dominant influence on fiscal policy. The article argues that spending cuts by the Australian federal government announced in 1996 had immediate effects on financial markets, with reduced long‐term interest rates of about 50 basis points in 1996–97. Using a modified version of the Treasury macroeconometric model of the Australian economy (TRYM), the article simulates the net macroeconomic effects of the expenditure cuts, fiscal consolidation and lower long‐term interest rates. The article finds that the program of budget consolidation had a sizeable short‐ and medium‐term impact on the economy, raising Gross Domestic Product by up to three‐quarters of a percentage point and reducing unemployment by 0.3 percentage points over the next two to three years. 相似文献

The Bank of England first acquired a macroeconomic model of the UK economy in early 1973, and used it for forecasting in June and July of that year. The initial model was obtained from the London Business School (LBS), but the last 14 years or so have, on the part of both the Bank and the LBS, led to developments which now make the models no closer to each other than to other large scale models of the UK. This article describes the structure and central properties of the current version of the Bank model, which has some 663 variables, 134 of which are modelled by behavioural equations, 153 by technical equations, 212 identities and 164 exogenous variables. In order to provide a transitional step between the kind of models with which most macroeconomists are familiar and the full scale version of the Bank model, one part of the article presents a very simple stylized version of the full model. This is a stepping stone to the full model which is described and analysed on a sectoral basis in Part 3, with a complete listing of equations in Part 4. Some of the simulation properties, and hence full model dynamic responses, are considered in Part 5. 相似文献

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
