Conservation auctions have the potential to increase the efficiency of payments to farmers to adopt conservation-friendly management practices by fostering competition among them. The literature considers bidders that have complete information about the costs of adoption and optimal bidding behavior reflects this information advantage. Farmers seek information rents and bids decrease when risk aversion increases because farmers are more averse to losing the auction. We contribute to the literature by allowing for cost risk. Our paper shows that farmers must balance the risk of losing the auction (thus foregoing information rent) with the risk of submitting a bid that is not high enough to pay the costs of adopting conservation practices (thus incurring losses). We design an experiment to trade off these two risks and examine how risk aversion affects bidding behavior when participants face different sources and levels of risk. Our experiment contributes to a small literature on experimental auctions with risky product valuations. We find that participants decrease their bids as risk aversion increases, even in auctions with cost risk, suggesting that the risk of losing the auction dominates. These findings uncover new challenges for the practical implementation of conservation auctions as an efficient policy instrument. 相似文献

Railroad deregulation has had tremendous effects on the level of costs and productivity gains. I use an unbalanced panel of railroads from 1978 through 1989 to estimate a translog cost function. I find that initially cost savings from partial deregulation were modest. However, by 1989, I find that cost savings were tremendous, with costs being up to 40 percent lower than they would have been under regulation. I also find that while initial effects of deregulation on productivity gains were large, these effects have fallen through time, and currently are comparable to pre-deregulation levels. 相似文献

It is reasonable to suggest that a portfolio manager with direct property diversified by sector or region is more interested in strategic than in tactical asset allocation. However, even with strategic allocations of property the portfolio manager needs a regular monitoring of the inter-relationships amongst assets comprising the portfolio to ensure that unexpected events do not 'permanently' alter such relationships. One procedure for ascertaining whether assets are inter-related over the long run (and therefore offer few diversification benefits) is through cointegration analysis. A difficulty with conventional cointegration analysis, however, is that it is unable to accommodate changes in equilibrium relationships that might occur due to unexpected structural changes. In this paper we apply the Gregory and Hansen cointegration procedure to consider how unexpected structural changes might affect the potential long run diversification benefits of assets held in an Australian property portfolio. 相似文献

This paper models tax competition between two countries that are divided into regions. In the first stage of the game, the strategy variable for each country is the division of a continuum of public goods between central and regional government provision. In the second stage, the central and regional governments choose their tax rates on capital. A country's decentralization level serves as a strategic tool through its influence on the mix of horizontal and vertical externalities that exists under tax competition. In contrast to standard tax competition models, decentralizing the provision of public goods may improve welfare. 相似文献

We study the efficiency of the Argentine banking system after the 2001–2002 crisis. The financial system had to be restructured from scratch and recovered jointly with the economy, but its productivity and average cost levels have been stagnant since 2007. The analysis includes efficiency frontier estimations for retail banks and a comparison of subsamples for different categories of banks for the period 2005–15. We try to determine whether public banks are more efficient than private ones, whether privatized are more efficient than always private, as well as national versus foreign entities. Our findings show a modest average efficiency of the system and quite similar efficiency rankings for the different groups of banks. On average, public tend to be slightly more cost efficient than private, and national are slightly more efficient than foreign. 相似文献

Aims: Prophylaxis with recombinant factor VIII (rFVIII) is the standard of care for severe hemophilia A in Sweden. The need for frequent injections with existing rFVIII products may, however, result in poor adherence to prophylaxis, leading to increased bleeding and long-term joint damage. Recombinant FVIIIFc (rFVIIIFc) is an extended half-life fusion protein which can offer prolonged protection and reduced dosing frequency. The objective of this study was to evaluate the cost-utility of prophylaxis with rFVIIIFc in severe hemophilia A from the perspective of the Swedish health system.Methods: A Markov model was built to estimate lifetime costs and benefits of prophylaxis with rFVIIIFc vs rFVIII products. Clinical outcomes were represented by annualized bleeding rate (ABR) and quality of life via disutility applied to bleeding events and injection frequency. Costs included the cost of FVIII for routine prophylaxis and bleed resolution. The pooled comparator was costed by weighting the cost of individual products by their market share.Results: In the base case, rFVIIIFc was dominant vs the pooled comparator. Savings of SEK 9.0 million per patient resulted from lower factor consumption for prophylaxis and bleed resolution. Fewer bleeds and reduced injection frequency yielded an estimated 0.59 quality-adjusted life years (QALYs). Results were sensitive to drug dosage and robust to variation in other parameters. Probabilistic sensitivity analysis suggested a greater than 85% probability of rFVIIIFc being cost-effective at a willingness-to-pay threshold of 500,000 SEK/QALY.Limitations: Due to unavailibilty of patient-level data, treatment benefit was based on a non-adjusted indirect comparison. Dosing and treatment outcomes were assumed to persist over the model duration in the absence of long-term outcome data.Conclusion: The results suggest that rFVIIIFc may be a cost-effective option for hemophilia A prophylaxis, generating greater quality of life and reduced costs for the Swedish payer compared to more frequently administered rFVIII alternatives. 相似文献

In this paper we report the findings of an economic experiment that examines the effects of an automated mitigation procedure
(AMP) on prices and capacity investment choices of suppliers in a wholesale electricity market. Specifically, we examine the
effects of different market power incentives on markets with and without an AMP. While we find that the AMP does not affect
overall investment in capacity, the most significant determinant of long-run prices is investment in new capacity. The AMP
also does not reduce long-run prices relative to markets without an AMP. Furthermore, our participants successfully manipulated
the AMP’s trigger price.

We report the results of experiments conducted over the internet between two different laboratories. Each subject at one site
is matched with a subject at another site in a trust game experiment. We investigate whether subjects believe they are really
matched with another person, and suggest a methodology for ensuring that subjects’ beliefs are accurate. Results show that
skepticism can lead to misleading results. If subjects do not believe they are matched with a real person, they trust too
much: i.e., they trust the experimenter rather than their partner.

This paper estimates the relationship between trade facilitation and trade flows using a panel of disaggregated manufactured goods for the 2000–2001 period for 75 countries. Four categories of trade facilitation are defined, measured and assessed for their impact on bilateral trade flows using a gravity model. The four measures of trade facilitation are: port infrastructure (air and maritime), customs environment, regulatory environments and e‐business infrastructure. The results suggest that raising global capacity halfway to the world average in the four areas would increase trade by $377 billion. Most regions of the world increase exports more than imports. In large part, this result stems from increased exports to OECD markets that is obtained through a country's own effort to improve ports, customs, regulations and services infrastructures. In addition, the results suggest that reform and capacity building in trade facilitation in areas related to GATT Articles V, VIII and X that are under discussion at the World Trade Organisation could expand trade and exports significantly. Many of the reform measures necessary to achieve this goal need not necessarily require large‐scale investment projects, but rather action in legal and administrative reform to facilitate trade. 相似文献
