We analyze the problem of eliminating an inefficient regulation, such as protection, in a dynamic model in which there is
incomplete information and unanimous approval from all parties involved is necessary. Existing firms have heterogeneous cost,
and efficiency requires some of them to shut down when the inefficient regulation is eliminated. The government can set up
a revelation mechanism, giving subsidies and requiring firms to exit the market at a given time depending on the information
collected. Under full commitment the optimal policy prescribes that some inefficient firms remain active and are subsidized.
The optimal policy takes a simple form, with at most two times at which the firms are allowed to exit.
We are very grateful to Matt Mitchell whose comments substantially improved the paper. 相似文献

The paper analyzes how (production and financial) inter-firm networks can affect firms’ default probabilities and observed default rates. A simple theoretical model of shock transfer is built to investigate some stylized facts on how firm-idiosyncratic shocks are allocated in the network, and how this allocation changes firm default probabilities. The model shows that the network works as a perfect “risk-pooling” mechanism, when it is both strongly connected and symmetric. But the “risk-sharing” does not necessarily reduce default rates, unless the shock firms face is lower on average than their financial capacity. Conceived as cases of symmetric inter-firm networks, industrial districts might have a comparative disadvantage in front of heavy crises. 相似文献

Collusion via Signalling in Simultaneous Ascending Bid Auctions with Heterogeneous Objects, with and without Complementarities 总被引:1,自引:0,他引:1
Collusive equilibria exist in simultaneous ascending bid auctions with multiple objects, even with large complementarities in the buyers' utility functions. The bidders collude by dividing the objects among themselves, while keeping the prices low. In the most collusive equilibrium the complementarities are never realized. The scope for collusion however narrows as the ratio between the number of bidders and the number of objects increases. 相似文献

This paper identifies the most important factors that influence the productivity of the urban fleet of a Logistics Service Provider (LSP). Through a regression analysis on a dataset from distribution warehouses of a single LSP, three main levers are shown to have significant impacts on productivity, namely the network design, the vehicle loading strategy, and the business environment wherein the operations are carried out. This paper contributes to bridge the gap about the lack of works addressing the efficiency of LSPs operating in urban areas, by performing a detailed empirical analysis instead of taking an aggregated company perspective. 相似文献

Global energy consumption is growing. The growth in energy consumption is now covered roughly equally by renewable energy resources and fossil energy resources. Nevertheless, crude oil, natural gas and coal continue to form the backbone of energy supplies. This means that the dependency of energy supplies on fossil energy resources will continue for the foreseeable future. In Germany as well, there is no end in sight of the country decreasing its high dependency on imports of fossil energy resources despite the high growth rate of renewables—and due in part to the decline in domestic production and the withdrawal from nuclear power generation. Crude oil, natural gas, hard coal and lignite with a share of around 80%, still make the largest contribution to the German and global primary energy consumption.All of the renewables together cover around 17% of global energy consumption. Despite the almost inexhaustible potential, making energy generation from renewable sources available at a large scale and commensurate with demand is still in its infancy. By way of contrast, very large reserves of fossil energy resources have already been developed for many years, and are being used in growing quantities. The global comparison of already produced and therefore consumed energy resources and the still existing reserves and resources, reveal that large non-depleted energy potential still exists in all regions around the world. Whilst the potential hardly appears to be touched in Austral-Asia, in the CIS and North America, only a small portion has been produced to date even in Europe. This wealth in resources is primarily attributable to the large deposits of coal found on all continents, which, unlike conventional crude oil and natural gas, are not restricted to a few special regions. Although the Middle East is an extremely important region for crude oil and natural gas, the minor coal reserves in the area mean that its overall potential is comparatively small. 相似文献

AbstractConcerns with growth have steadily advanced since the Limits to Growth report due particularly to human impacts on the natural environment. Since that time, neoliberal capitalism has become increasingly reliant on growth exacerbating these problems. The destructive outcomes of these strategies has led to a growing interest in degrowth. Analysts are examining how we can create economies that eschew a growth imperative while still supporting human thriving. Tourism as a key facet of capitalism is implicated in these issues and recent concerns with “overtourism” are only one symptom of the problem. This article presents a conceptual consideration of issues of degrowth in tourism. It examines current tensions in international mobility and argues just and sustainable degrowth will require greater attention to equity. This analysis suggests that essential to such an agenda is redefining tourism to focus on the rights of local communities and a rebuilding of the social capacities of tourism. This article argues for the redefinition of tourism in order to place the rights of local communities above the rights of tourists for holidays and the rights of tourism corporates to make profits. 相似文献

In auctions with correlated types it is possible to design mechanisms such that full surplus extraction can be obtained as the outcome of an equilibrium in which agents use (weakly) dominant strategies. However, it is not assured that the outcome is unique. We present an example in which no mechanism can yield the full surplus extraction outcome as the unique Bayesian equilibrium outcome. Next we show that in the standard auction model the multiplicity problem can be fully resolved using sequential mechanisms, i.e., we show that it is possible to obtain the full surplus extraction outcome as the unique perfect Bayesian equilibrium outcome.Journal of Economic LiteratureClassification Numbers: D44; D70. 相似文献
