Best-price Guarantees as a Quality Signal
No full textThis paper shows that best-price guarantees can enhance welfare, in contrast to findings in recent literature. While a high-quality monopolist can signal its quality strictly through high prices, using both price and a best-price guarantee may allow the firm to signal its quality with a smaller price distortion. A low-quality monopolist will not mimic its high-quality counterpart by offering a best-price guarantee, because the accompanying restrictions are too costly. Best-price guarantees are similar to money-back guarantees and other more general contracts in their ability to allow less costly signaling. The welfare enhancing capabilities of these contracts imply that the antitrust authorities should regard them more favorably.Most favored customer; MFCC; best-price guarantees; signaling; game theory; industrial organization
Forward-looking versus backward-looking Taylor rules
No full textThis paper analyzes the restrictions necessary to ensure that the policy rule used by the central bank does not introduce real indeterminacy into the economy. It conducts this analysis in a flexible price economy and a sticky price model. A robust conclusion is that to ensure determinacy, the monetary authority should follow a backward-looking rule where the nominal interest rate responds aggressively to past inflation rates.Monetary policy
Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
Progress of international hydrogen production network for the thermochemical Cu–Cl cycle
No full textThis paper presents recent advances by an international team which is developing the thermochemical copper–chlorine (Cu–Cl) cycle for hydrogen production. Development of the Cu–Cl cycle has been pursued by several countries within the framework of the Generation IV International Forum (GIF) for hydrogen production with the next generation of nuclear reactors. Due to its lower temperature requirements in comparison with other thermochemical cycles, the Cu–Cl cycle is particularly well matched with Canada's Generation IV reactor, SCWR (Super-Critical Water Reactor), as well as other heat sources such as solar energy or industrial waste heat. In this paper, recent developments of the Cu–Cl cycle are presented, specifically involving unit operation experiments, corrosion resistant materials and system integration.Atomic Energy of Canada LimitedOntario Research Excellence FundNatural Sciences and Engineering Research Council of CanadaUniversity Network of Excellence in Nuclear Engineering (UNENE)Canada Research Chairs progra
Price-Level Targeting–A Real Alternative to Inflation Targeting?
No full textThis paper reviews price-level targeting in the light of current theoretical knowledge and past practical experience. The authors discuss progress in the economic debate on this issue, starting with the traditional arguments discussed in the early 1990s and ending with the most recent literature from the beginning of the new millennium. They devote special attention to the issues of the zero interest rate bound, time consistency, and communication. Practical experience from Sweden in the 1930s and Czechoslovakia in the first few years after WWI is used to illustrate the advantages and disadvantages of price-level targeting. Finally, the similarities of price-level and inflation developments with hypothetical outcomes under price-level targeting are investigated in selected inflation-targeting countries.price-level targeting, deflation, zero bound, communication, time inconsistency
ŻYCIE UKRYTE W SŁOWIE. "BEKSIŃSCY. PORTRET PODWÓJNY" MAGDALENY GRZEBIAŁKOWSKIEJ W ŚWIETLE POSTSTRUKTURALIZMU
No full textLife Hidden in Words. Magdalena Grzebiałkowska\u27s "Beksińscy. Portret podwójny" and Poststructuralism
The article analyzes Magdalena Grzebiałkowska\u27s biographical "Beksińscy. Portret podwójny" which focuses on the lives of Zdzisław Beksiński and Tomasz Beksiński. The author looks at the construction of the biography and its relationship to poststructuralism, which allows for an appreciation of the literary features of the book. He points to how the specificity of the content, language, a mode of narration in Grzebiałkowska\u27s book make it a full-fledged literary work itself. As such the book departs from a typical biographical scheme. Juxtaposing the book with poststructural ideas leads to the reconsideration of the role of the author in the process of shaping of a biographical narrative
Reconciling Microeconomic and Macroeconomic Estimates of Price Stickiness
No full textThis paper attempts to reconcile the high estimates of price stickiness from macroeconomic estimates of a New-Keynesian Phillips Curve (NKPC) with the lower values obtained from surveys of firms’ pricing behaviour. This microeconomic evidence also suggests that the frequency with which firms adjust their prices varies across sectors. The paper shows that in the presence of this heterogeneity, estimates of aggregate price stickiness from microeconomic and macroeconomic data should differ. Heterogeneity in firms’ pricing decisions, as well as a more realistic production structure, is introduced into an otherwise standard New-Keynesian model. Using a model calibrated with microeconomic pricing survey data for Australia, the paper shows that estimates of the NKPC considerably overstate the true degree of price stickiness and may falsely suggest that some prices are indexed to past inflation. These problems arise because of a type of misspecification and a lack of suitable instruments.separate by New-Keynesian Phillips Curve; inflation
Systems, methods and devices for the capture and hydrogenation of carbon dioxide with thermochemical Cu—Cl and Mg—Cl—Na/K—CO2 cycles
No full textSystems, methods, and devices for producing hydrogen and capturing CO2 from emissions combine both H2 production and CO2 capture processes in forms of thermochemical cycles to produce useful products from captured CO2. The thermochemical cycles are copper-chlorine (Cu—Cl) and magnesium-chlorine-sodium/potassium cycles (Mg—Cl—Na/K—CO2). One system comprises a Cu—Cl cycle, a CO2 capture loop, and a hydrogenation cycle. Another system comprises an Mg—Cl—Na/K—CO2 cycle and a hydrogenation cycle. Devices for hydrogen production, CO2 capture, hydrogenation, and process and equipment integration include a two-stage fluidized/packed bed, hybrid two-stage spray-fluidized/packed bed reactor, a two-stage wet-mode absorber, a hybrid two-stage absorber, and a catalyst packed/fluidized bed reactor
