近年来,随着我国越来越重视对环境的保护,在对污水处理过程中也加入了更多的环保性装置。当前,我国大多都使用单塔加压气提装置对鲁奇炉污水进行处理,这种方法主要是对污水中的某些液态分子而进行一定程度上的分离,以达到对污水进行处理的目的。随着我国对单塔加压气提装置进行鲁奇炉污水处理的使用力度不断加大,我国已经在对污水处理这方面取得了进一步的进展,也对环境进行了更大强度上的保护。为了更好的对我国鲁奇炉污水进行处理,文章主要对单塔加压气提装置在鲁奇炉污水处理中的应用进行了简要的分析。     

Sources of value in takeovers: Synergy or restructuring–implications for target and bidder firms

Advocates of the market for corporate control argue that takeover bids should be accepted because unsuccessful targets tend to lose market value. Other researchers argue that takeover bids should be rejected because the combined firms often perform poorly. However, missing in this debate is the influence of the source of takeover gains on the decision to reject or accept takeover bids. This study posits that value from takeovers can be created by synergy or restructuring. The study suggests that only if the synergy component is dominant should the target firm agree to be taken over. The study then tests the dominance of the source of value in takeovers by examining takeovers that were unsuccessful. The study concludes that, first, restructuring, not synergy, motivated the sample studied and target firms can create the same value independently. Second the need for restructuring was industry-wide. However, even if restructuring is the motive behind a takeover, the target firm has to carry out the restructuring, failing which it does not create any value. The study also suggests reasons for the ambiguous findings in the strategic management merger literature.

Bid Roundness Under Collusion in Japanese Procurement Auctions

We analyze the “roundness level” of bids—defined as the number of zeros at the end of the bid—in public procurement auctions for construction works in Okinawa Prefecture, Japan, where a bid-rigging case was filed. We hypothesize that bid rigging increases the roundness of bids through the bid coordination process. Specifically, winners choose round numbers to avoid any miscommunication when they announce their planned bids to other ring members, and losers prefer round numbers when they arbitrarily bid above the winning bid. We find that (1) there is a positive relationship between the roundness of a bid and its relative value as a fraction of the reserve price, (2) the roundness of bids is higher when collusion is active than when it is inactive, (3) among the ring bids, the roundness of the lowest bids is even higher than that of the other bids, and (4) bids by non-ring members are also round when collusion is active.     

Buyer Alliances as Countervailing Power in WIC Infant-Formula Auctions

State agencies in infant-formula procurement auctions receive lower bids when they are in buyer alliances than when they are unallied. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) uses an auction to procure infant formula. Manufacturers bid on the right to be an agency’s sole supplier by offering a rebate on formula sold through WIC. Agencies frequently join together in buyer alliances. An empirical estimation shows that bids are lower to alliances and that lower prices result because alliances are heterogeneous. Results suggest that when heterogeneity is not controlled, bids decline with alliance size, which has policy implications because Congress recently limited alliance size.     

Price Adjustment Policies in Procurement Contracting: An Analysis of Bidding Behavior

The fluctuations in fuel prices over the past decade led a number of government agencies to introduce price adjustment clauses in procurement contracting. Those clauses were primarily designed to reduce contractors’ uncertainty without considering the impact of such initiatives on bidding and the budget. We analyze a newly constructed, detailed panel of observations on bids for construction contracts and compare bidding behavior across periods and projects, and across items within projects. Estimates from a difference‐in‐differences approach, indicate that bidding becomes more aggressive and less dispersed after the implementation of this policy. The difference is more pronounced when we consider itemized bids than overall project bids. Alternative techniques of regression discontinuity and nonparametric estimation are applied and yield consistent results.

Explaining cost escalation on Ireland's national broadband plan: A path dependency perspective

Ireland's national broadband plan (NBP), announced in 2012, aimed to provide access to a minimum of 30 Mbps download speed to all households in the country ahead of the EU's Digital Agenda for Europe 2020 target for such speeds. The projected cost of the government subsidy was originally €175 million. However, when the contract for the procurement of the NBP was eventually signed in 2019 the estimated subsidy had risen to between €2.2 and €2.9 billion. Using a path dependency framework, this paper finds that the escalation in the cost of subsidy was driven by two main factors. First, the decision to roll out fibre-to-the-premises (FTTP) technology was inconsistent with the geographic/legacy path dependencies related to Ireland's low-density rural population. Second, the gap-funding/PPP procurement model adopted for the intervention failed to attract competitive bids and was at odds with the competitive path dependency and the dominant role of the incumbent operator.     

LICENSE AUCTIONS WHEN WINNING BIDS ARE FINANCED THROUGH DEBT*

We study an auction where two licenses to operate on a new market are sold and winning bidders finance their bids on the debt market. Higher bids imply higher debts which affects product market competition. When debt induces firms to compete more aggressively, retail prices are lower than in a model without debt, as are auction revenues. When debt induces firms to compete less aggressively, retail prices are higher than in a model without debt, and the effect on auction revenues is ambiguous. Net firm profits are always higher than in a model without debt due to endogenous credit rationing.     

Bid Coordination in Sponsored Search Auctions: Detection Methodology and Empirical Analysis*

Bid delegation to specialized intermediaries is common in internet ad auctions. When the same intermediary bids for competing advertisers, its incentive to coordinate client bids might alter the functioning of the auctions. This study develops a methodology to detect bid coordination and presents a strategy to estimate a bound on the search engine revenue losses imposed by bid coordination. When the method is applied to data from auctions held on a major search engine, coordination is detected in 55% of the cases of delegated bidding and the search engine's revenue loss ranges between 5.3% and 10.4%.
