Antitrust enforcement concerning monopolies, mergers, and cartels is converging across all market‐oriented economies in the world. This convergence is based upon neoclassical economic analysis of industrial organization. The role of empirical economic analysis, however, has not converged as rapidly as the conceptual model because different countries have different enforcement institutions and strategies. This article explains how antitrust enforcement has evolved over time from public agencies to a market for enforcement that admits private parties. Private party law suits, and especially class action law suits on behalf of groups such as farmers and consumers, is a mechanism for redressing the often superior legal and economic resources that defendant corporations have and public agencies do not have. Enforcement and the role of empirical analysis are compared in the United States and other countries. Examples of enforcement from different countries illustrate the strengths and weaknesses of different approaches. Finally, some insights explain how economists function in enforcement and the attributes required for success. 相似文献

Onshore wind energy utilisation in Germany has developed very dynamically in the last decade. This has mainly been driven
by the renewable energy laws that systematically support the expansion of renewable energy in the electricity sector. In 2009
a revised law with increased feed-in tariffs for wind energy has come into force. Existing studies already predict a wide
range of development patterns under the Renewable Energy Sources Acts 2000 and 2004. This paper investigates the long term
impact of different feed-in tariffs implemented by the legislative authorities and it provides corresponding future development
patterns of onshore wind energy utilisation in Germany. The underlying System Dynamics model considers technical as well as
economic conditions and constraints. The approach and the model’s results are contrasted with other published predictions
qualitatively and quantitatively. This comparison shows that the model’s outcome lies in the range of predictions by existing
studies, but also shows some interesting differences.
Zusammenfassung Die Entwicklung der Windenergienutzung in Deutschland wahrend der letzten Dekade verlief sehr dynamisch. MagBgeblich dafur war die systematische Forde-rung mittels der Erneuerbare Energien Gesetze (EEG) bzw. deren Vorlaufer. Vom Jahr 2009 an gilt ein uberarbeitetes Gesetz, welches u.a. erhohte Einspeisever-gutungen furWindenergie beinhaltet.Vorliegende Studien, die sich mit derzu-kunftigen Entwicklung auseinandersetzten, zeigen bereits deutlich unterschied-liche Szenarien fur die Entwicklung unter dem EEG 2000 und 2004. Diese Arbeit setzt sich mit den langfristigen Auswirkungen der verschiedenen vom Gesetz-geber festgelegten Einspeisetarife auseinander und stellt entsprechend unter-schiedliche Ausbauszenarien fur die deutsche Onshore Windenergienutzung dar. Das zugrunde liegende System Dynamics Modell berucksichtigt dabei sowohl technische als auch okonomische Parameter. Der Ansatz sowie die Ergebnisse werden anderen veroffentlichten Prognosen gegenubergestellt. Die Ergebnisse liegen innerhalb der Spannbreite der anderen berucksichtigten Studien, zei-gen jedoch auch interessante Unterschiede.相似文献

Abstract. This paper analyzes the interaction between structural change and labor market dynamics in West Germany, during a period when industrial employment declined by more than 30% and service sector employment more than doubled. Using transition data on individual workers, we document a marked increase in structural change and turbulence, in particular since 1990. Net employment changes resulted partly from an increase in gross flows, but also from an increase in the net transition 'yield' at any given gross worker turnover. In growing sectors, net structural change was driven by accessions from non-participation rather than unemployment; contracting sectors reduced their net employment primarily via lower accessions from non-participation. German reunification and Eastern enlargement appear to have contributed significantly to this accelerated pace of structural change. 相似文献

Competitive International Trade Theory has frequently been criticized for its intensive use of diagrams (as opposed to more formal mathematics, such as calculus and algebra), prompted by its typical use of small dimensional models. This paper selects ten diagrams useful in capturing the essence of important trade theory and illustrating their usefulness even in higher-dimensional cases. 相似文献

While much has been said and written about the effect of the 2002 Sarbanes-Oxley Act (SOX), one consequence of the new regulation that has been largely neglected is the law's dramatic impact on how audits are bought and sold in the United States. Prior to SOX, the process was clear and simple: accounting firm partners would meet with the publicly held client company's C-level executives to complete the exchange. When SOX was passed, Congress took the buying decision out of the hands of the client company's executives and placed it in the hands of the company's external audit committee. As this inter-disciplinary research will explain, this change—and other similar changes emanating from the “independence” provisions in SOX—has forever complicated the client-auditor exchange. Based on the literature in business-to-business selling, this research proposes two models—one centered around the concept of a “buying center” and another around “selling team” theory—in an effort to advance thinking in this area, and help both client companies and accounting firms operate in this new environment. 相似文献

This paper presents a survey of the use of homotopy methods in game theory. Homotopies allow for a robust computation of game-theoretic
equilibria and their refinements. Homotopies are also suitable to compute equilibria that are selected by various selection
theories. We present the relevant techniques underlying homotopy algorithms. We give detailed expositions of the Lemke–Howson
algorithm and the van den Elzen–Talman algorithm to compute Nash equilibria in 2-person games, and the Herings–van den Elzen,
Herings–Peeters, and McKelvey–Palfrey algorithms to compute Nash equilibria in general n-person games. We explain how the main ideas can be extended to compute equilibria in extensive form and dynamic games, and
how homotopies can be used to compute all Nash equilibria. 相似文献

Fixed Costs, Foreign Direct Investment, and Gravity with Zeros 总被引:1,自引:0,他引:1
Fixed costs play a crucial role in current models of foreign direct investment (FDI), yet they are almost entirely ignored in empirical treatments of FDI. We fill this gap by using a 1989–2001 panel of FDI flows into Iceland to examine the determinants of fixed costs for multinational firms and how these influence aggregate patterns of investment. Our additions to research in the field include usage of several natural-resource variables, and the analysis of data on initial entry of FDI into a developed country. We use the Heckman two-step procedure, which allows us to account for fixed costs and their impact on estimation. Taken together, we find that the standard OLS approach to the data incorrectly links the quantity of FDI to source-country variables while in fact most of their role is in determining whether FDI takes place at all. 相似文献

This article reflects on how close World Trade Organization members came to reaching agreement in Geneva last July on the key agricultural and industrial issues at the heart of the Doha Round. But since 6 November, when the text of this article was finalised, the global economy has been in continuing decline and there was insufficient convergence on outstanding issues to justify a new ministerial meeting tentatively planned for December. The prospects of completing the round by the end of 2009 have therefore weakened. 相似文献

MONETARY TRANSMISSION MECHANISM IN CENTRAL AND EASTERN EUROPE: SURVEYING THE SURVEYABLE 总被引:2,自引:0,他引:2
Abstract. This paper surveys recent advances in empirical studies of the monetary transmission mechanism, with special attention to Central and Eastern Europe (CEE). Our results indicate that the strength of the exchange rate pass-through substantially declined over time mainly due to a fall in inflation rates and to some extent due to the so-called composition effect. The asset price channel is weak and is likely to remain weak because of shallow stock and private bond markets and because of low stock and bond holdings of domestic households. House prices may become an exception with booming mortgage lending and with high owner occupancy ratios. While the credit channel could be a powerful channel of monetary transmission – as new funds raised on capital markets are close to zero in CEE – it is actually not, as both commercial banks and non-financial corporations can escape domestic monetary conditions by borrowing from their foreign mother companies. The moderately good news, however, is that those banks and firms are influenced by monetary policy in the euro area because their parent institutions are themselves subjected to the credit channel in the euro area. 相似文献

We provide a comparison of bidding behavior between multi-round and single-round auctions considering bid lettings for asphalt construction contracts that are known to have primarily private costs. Using a reduced-form difference-in-difference approach as well as the nonparametric estimation technique that was proposed by Racine and Li (J Econom 119(1):99–130, 2004) we find that bidding is more aggressive in a sequential multi-round setting than in a simultaneous single-round format. We explore potential causes for the bidding difference across formats that are related to synergies and the level of bidder participation. 相似文献
