We propose a Markov switching cointegration approach to assess long run fiscal sustainability. This method allows us to simultaneously: (1) test for cointegration in the presence of significant fiscal policy changes; (2) assess the type of fiscal regime that a country experienced at a given period and (3) analyse the timing of the transition between the estimated regime types. Given its flexibility, our approach enable us to uncover a richer and more complex dynamics in the analysis of fiscal sustainability, which standard linear cointegration methods fail to capture. 相似文献

In this study, we examine the price process of eBay online auctions. We pool sparse and unevenly spaced bidding histories of individual auctions, resulting in an unbalanced panel of bids. Since the price processes of online auctions are monotonically increasing within individual auctions and exhibit a substantial degree of heterogeneity, we propose a monotone series estimator for panel data with auction-specific slopes for a common relative price growth curve. We generalize Ramsay’s (1998, J R Stat Soc B 60(2):365–375) monotone series estimator to fit our panel model of the price process. We apply the proposed model and estimator to eBay auctions of a popular hand-held device (a Palm PDA). The results are shown to capture closely the overall pattern of observed price dynamics. In particular, the early bidding, mid-auction bidding drought, and end-auction bid sniping are well approximated by the estimated price curve. 相似文献

Invasive animal pests reduce crop and livestock output, require management and control measures, and threaten native plants, animals and their habitat. The agricultural and management costs are often directly measurable. But the costs to protect threatened native plants and animals are harder to assess. The Rural Lands Protection Boards were the government agency in New South Wales that managed invasive animals. An analysis of their decisions provided the opportunity to estimate the costs of protecting native species. The number of native plants and animals threatened by invasive pests was modelled against the expenditure, area, pest abundance, climate and location of 38 Board districts. There was a strong negative relationship between the number of threatened native species and Board expenditure. This relationship was interpreted to estimate the marginal cost of protecting a threatened native species, the downward shift in the supply curve necessary to protect all threatened native species, and the gains from the shift in the form of cost savings in the continued protection of non-threatened native species. These results value some of the costs that invasive animal pests impose on the environment. 相似文献

Land-use change has a significant impact on the world’s ecosystems. Changes in the extent and composition of forests, grasslands, wetlands and other ecosystems have large impacts on the provision of ecosystem services, biodiversity conservation and returns to landowners. While the change in private returns to landowners due to land-use change can often be measured, changes in the supply and value of ecosystem services and the provision of biodiversity conservation have been harder to quantify. In this paper we use a spatially explicit integrated modeling tool (InVEST) to quantify the changes in ecosystem services, habitat for biodiversity, and returns to landowners from land-use change in Minnesota from 1992 to 2001. We evaluate the impact of actual land-use change and a suite of alternative land-use change scenarios. We find a lack of concordance in the ranking of baseline and alternative land-use scenarios in terms of generation of private returns to landowners and net social benefits (private returns plus ecosystem service value). Returns to landowners are highest in a scenario with large-scale agricultural expansion. This scenario, however, generated the lowest net social benefits across all scenarios considered because of large losses in stored carbon and negative impacts on water quality. Further, this scenario resulted in the largest decline in habitat quality for general terrestrial biodiversity and forest songbirds. Our results illustrate the importance of taking ecosystem services into account in land-use and land-management decision-making and linking such decisions to incentives that accurately reflect social returns. 相似文献

We employ cooperative bargaining theory and Nash’s ‘rational threats’ idea to cast light on the biodiversity bargaining problem. The problem of global environmental negotiations is argued to be of the nature of a bargaining problem, in which bargainers must agree on the distribution of cooperative surplus in order to move to the bargaining frontier. We discuss the importance of both efficiency (bargaining frontier) and fairness (recognition of characteristics of bargainers) in the choice of the appropriate contract. We show that the incremental cost contract, used to resolve the biodiversity bargaining problem, is of the form of an extreme point contract that fails to recognise the contributions of the South to the production of cooperative surplus. A rational response to such a contract is the use of threats of biodiversity destruction. Contracts must evince both efficiency and fairness in order to represent lasting solutions. 相似文献

We offer an analysis of the existence of a positive relationship between minimum wages and economic growth in a simple one-sector overlapping generations economy à la Romer (J Polit Econ 94:1002–1037, 1986), in the case of both homogeneous and heterogeneous labour and without considering any growth-sustaining externalities which the minimum wage can generate. Assuming also the existence of unemployment benefits financed with balanced-budget consumption taxes not conditional upon age, we show that the minimum wage can promote economic growth and welfare despite the occurrence of unemployment. There may also exist a growth- and welfare-maximising minimum wage. 相似文献

China reformed value-added tax (VAT) by removing investment from the tax base in northeastern provinces in 2004, which is a “natural experiment” of its tax system. Using difference-in-differences method, this paper for the first time investigates the impact of VAT reform on China firms’ fixed asset investment, employment behavior, innovative activities, and productivity, and furthermore discusses the impact of firm behavior on industrial structural upgrade and employment with a firm-level panel data of large and medium-sized manufacturing enterprises in China. We find that VAT reform significantly promotes firms’ fixed asset investment, and increases firms’ capital-labor ratio and productivity; while enhancement of firms’ productivity is mainly achieved by means of substituting labor with capital, rather than independent technology innovation; meanwhile, VAT reform distinctly decreases employment. Our findings have essential policy implications on the extension of VAT reform in the entire China. 相似文献

The complete Incremental Cost Test for cross-subsidies can be difficult to apply to a multi-product enterprise because every possible subset of products must be tested. However, this combinatorial problem can be avoided when the enterprise’s cost function is sub-modular by identifying the smallest subset of products causing the maximum cross-subsidy. This subset contains all of the products, and only those products, that are responsible for the cross-subsidies left by a stipulated set of prices. In addition, the subset can often be identified with a simple and efficient Myopic Algorithm. The algorithm should be particularly useful as a method for detecting cross-subsidies in regulated enterprises and networks because the cost functions for these industries are typically sub-modular. 相似文献

We examine whether the payoff dominant sequential-move (Stackelberg) outcome is realized when timing is endogenized. We adopt the observable delay game formulated by Hamilton and Slutsky [Games Econ Behav 2(1):29–46, 1990]. We find that if one sequential-move outcome is payoff dominant, either (i) the outcome both players prefer is the unique equilibrium; or (ii) two sequential-move outcomes are equilibria and the one both players prefer is risk dominant. In other words, no conflict between payoff dominance and risk dominance in the observable delay game exists, in contrast to other games such as (non pure) coordination games. We also find that even if one of two sequential-move outcomes is the unique equilibrium outcome in the observable delay game, it does not imply that the equilibrium outcome is payoff dominant to the other sequential-move outcome. 相似文献
