To support national environmental policy, it is desirable to forecast and analyse environmental indicators consistently with economic variables. However, environmental indicators are physical measures linked to physical activities that are not specified in economic models. One way to deal with this is to develop environmental satellite models linked to economic models. The system of models presented gives a frame of reference where emissions of greenhouse gases, acid gases, and leaching of nutrients to the aquatic environment are analysed in line with – and consistently with – macroeconomic variables. This paper gives an overview of the data and the satellite models. Finally, the results of applying the model system to calculate the impacts on emissions and the economy are reviewed in a few illustrative examples. The models have been developed for Denmark; however, most of the environmental data used are from the CORINAIR system implemented in numerous countries.  相似文献

Benefit shifting: The case of sickness insurance for the unemployed   总被引:1,自引:0,他引:1  
Morten Henningsen   《Labour economics》2008,15(6):1238-1269
This study describes the probability of transition from unemployment with unemployment insurance (UI) to sickness insurance (SI), using a proportional hazard duration model and a large register-based dataset. The combination of limited UI duration and the fact that SI rights do not depend on remaining UI, creates an incentive to use SI to effectively extend UI. The separate effects of elapsed unemployment duration and of UI duration on hazard rates are identified through a reform of the UI system. The estimated hazard rate for transition from unemployment to SI increases sharply the last months before UI exhaustion. The spikes are larger for diagnosis for mental illness, and vary across individuals, but are present for all groups and all diagnoses.  相似文献

Collection of recyclable materials is a major part of reverse logistics and an important issue in sustainable logistics. In this paper we consider a case study where paper and glass are collected from recycling cubes and transported to a treatment facility and processed for reuse. We show how outsourcing the planning and transportation of this service may result in conflicts of interest and unsustainable solutions. Finally, we suggest an alternative payment structure which can lead to a common goal, overall financial sustainability, and an improved financial situation for both the public company and the logistics provider.  相似文献

This paper analyses a regulated firms incentives to undertake catching-up investments when the firm has private information about the initial technology and the regulator is unable to commit himself to incentive contracts prior to the firms investment decision. In the absence of commitment power, the firm takes into account that the investment decision may serve as a signal to the regulator about the firms initial technology. Any pure strategy equilibrium of the signaling game is shown to be pooling in the sense that the efficient type mimics the inefficient type by investing. By not following this strategy, the efficient type reveals its efficiency to the regulator, who responds by inducing the firm to produce without rents. Restricting attention to undefeated pooling equilibria, the level of investment is shown to be lower than the first-best level.  相似文献

We estimate a model of house prices, combined loan‐to‐value ratios (CLTVs) and trade and foreclosure behavior. House prices are only observed for traded properties and trades are endogenous, creating sample‐selection problems for existing approaches to estimating CLTVs. We use a Bayesian filtering procedure to recover the price path for individual properties and produce selection‐corrected estimates of historical CLTV distributions. Estimating our model with transactions of residential properties in Alameda, California, we find that 35% of single‐family homes are underwater, compared to 19% estimated by existing approaches. Our results reduce the index revision problem and have applications for pricing mortgage‐backed securities.  相似文献

The political economy of agricultural policies – why certain interventions may be preferred by political leaders rather than others – is well recognized. This paper explores a perspective that has previously been neglected: the political economy of the agricultural statistics. In developing economies, the data on agricultural production are weak. Because these data are assembled using competing methods and assumptions, the final series are subject to political pressure, particularly when the government is subsidizing agricultural inputs. This paper draws on debates on the evidence of a Green Revolution in India and the arguments on the effect of withdrawing fertilizer subsidies during structural adjustment in Nigeria, and finally the paper presents new data on the effect of crop data subsidies in Malawi. The recent agricultural census (2006/7) indicates a maize output of 2.1 million metric tonnes, compared to the previously widely circulated figures of 3.4 million metric tonnes. The paper suggests that ‘data’ are themselves a product of agricultural policies.  相似文献

Danish farmers have been far less interested in agri-environmental subsidy schemes (AES) than anticipated. In order to examine how to improve the appeal of such schemes, a choice experiment was conducted concerning 444 Danish farmers’ preferences for subsidy schemes for pesticide-free buffer zones. A random parameter logit framework was used to capture heterogeneity among farmers. Our results indicate that 1) the vast majority of farmers are willing to trade off the size of the subsidy for less restrictive scheme requirements and that 2) the amount of the subsidy they are willing to trade off varies with specific scheme requirements, suggesting which features are most important for successful policy design. Our results suggest that farmers value flexible contract terms higher than reduced administrative burdens. Finally, we suggest a practical approach to estimating a monetary value of farmers’ reluctance to participate in AES. While the trade off's that farmers are willing to make between subsidy size and individual scheme requirements are case specific, our results concerning increased use of farm advisors, farmers ability of valuing different types of flexibility, and our attempt to place a monetary value on farmers’ reluctance to engage in regulatory subsidy schemes have a potentially broader application platform.  相似文献

This paper examines employee flows and the association with firm earnings and interest rates. We use administrative employer–employee matched panel data from Denmark spanning 17 years and hence exploit actual data on employee arrivals (labor inflows) and departures (labor outflows). Three main findings emerge. First, we condition by firms’ economic conditions. Departures predict earnings increases for prior-year loss firms, while they predict earnings decreases for prior-year profit firms, suggesting that this conditioning can help explain the mixed results in the literature. Arrivals predict earnings increases, though only for prior-year profit firms. These effects are stronger for high-paid employees than for low-paid ones. Second, the effects of departures are generally larger than the effects of arrivals, consistent with departures disrupting operations. Third, we find that lenders price employee flow information but only for departures of high-paid employees, despite the predictive ability of the flow of other employees for future earnings. Overall our results suggest that employee flows predict firm financial performance but are only partially priced by lenders.  相似文献

This paper formulates a novel test to assess whether, and to what extent, firms might be using low-price guarantees to discourage their rivals from cutting prices. The test is based on a comparison of paired observations of advertised prices that are set by competing firms at the same point in time on similar items, where one price is set by a firm that has a low-price guarantee and the other by a firm that does not have a low-price guarantee. Using data on retail tire prices, we find that the majority of paired observations involving firms that have price-matching guarantees are consistent with what one would expect if firms were using them to discourage price cutting, whereas the majority of paired observations involving firms that have price-beating guarantees are not. This suggests that price-matching and price-beating guarantees may be serving different purposes. The evidence also suggests that guarantees that apply to advertised prices only may be serving different purposes than guarantees that apply to both advertised and selling prices.  相似文献
