We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found. 相似文献

We investigate the interplay between environmental policy, incentives to adoptnew technology, and repercussions on R&D. We study a model where a monopolistic upstream firm engages in R&D and sells advanced
abatement technology to polluting downstream firms. We consider four different timing and commitment regimes of environmental
tax and permit policies: ex post taxation (or issuing permits), interim commitment to a tax rate (a quota of permits) after
observing R&D success but before adoption, and finally two types of ex antecommitment before R&D activity, one with a unique tax rate (quota of permits), the other one with a menu of tax rates (permit
quotas). We study the second best tax and permit policies and rank these with respect to welfare. In particular, we find that
commitment to a menu of tax rate dominates all other policy regimes. 相似文献

Synopsis It has been difficult to make progress in the study of ethnicity and nationalism because of the multiple confusions of analytic
and lay terms, and the sheer lack of terminological standardization (often even within the same article). This makes a conceptual
cleaning-up unavoidable, and it is especially salutary to attempt it now that more economists are becoming interested in the
effects of identity on behavior, so that they may begin with the best conceptual tools possible. My approach to these questions
has been informed by anthropological and evolutionary-psychological questions. I will focus primarily on the terms ‘ethnic
group’, ‘nation’, and ‘nationalism’, and I will make the following points: (1) so-called ‘ethnic groups’ are collections of
people with a common cultural identity, plus an ideology of membership by descent and normative endogamy; (2) the ‘group’
in ‘ethnic group’ is a misleading misnomer—these are not ‘groups’ but categories, so I propose to call them ‘ethnies’; (3) ‘nationalism’ mostly refers to the recent ideology that ethnies—cultural communities
with a self-conscious ideology of self-sufficient reproduction—be made politically sovereign; (4) it is very confusing to
use ‘nationalism’ also to stand for ‘loyalty to a multi-ethnic state’ because this is the exact opposite; (5) a ‘nation’ truly
exists only in a politician’s imagination, so analysts should not pretend that establishing whether something ‘really’ is
or is not ‘a nation’ matters; (6) a big analytic cost is paid every time an ‘ethnie’ is called a ‘nation’ because this mobilizes
the intuition that nationalism is indispensable to ethnic organization (not true), which thereby confuses the very historical
process—namely, the recent historical emergence of nationalism—that must be explained; (7) another analytical cost is paid
when scholars pretend that ethnicity is a form of kinship—it is not. 相似文献

Market Structure and Risk Taking in the Banking Industry 总被引:1,自引:0,他引:1
We demonstrate that the common view according to which an increase in competition leads banks to increased risk taking fails to hold in an environment where homogeneous loss averse consumers can choose in which bank to make a deposit based on their knowledge of the riskiness incorporated in the banks outstanding loan portfolios. With an exclusive focus on imperfect competition we find that banks incentives for risk taking are invariant to a change in the banking market structure from duopoly to monopoly. Finally, we show that deposit insurance would eliminate the gains from bank competition when banks use asset quality as a strategic instrument.revised version received October 15, 2003 相似文献

The paper demonstrates how various parametric models for duration data such as the exponential, Weibull, and log-normal may be embedded in a single framework, and how such competing models may be assessed relative to a more comprehensive one. To illustrate the issues addressed, the survival patterns of marriages among 1203 Swedish men born 1936–1964 are studied by parametric and non-parametric survival methods. In particular, we study the sensitivity of model-choice with respect to level of aggregation of the time variable; and of covariate-effects with respect to the model chosen. In accordance with previous works our empirical results indicate that the choice of a parametric model for the duration variable is affected by the level of time aggregation. In contrast to previous results, however, our analysis shows that estimates of covariate effects are not always robust to distributional assumptions for the duration variable. 相似文献

This paper explores the critical factors which affect the innovation proccess. Some ways in which some of these factors can be influenced by appropriate policy measures are discussed. In particular, the role of the federal government in promoting innovation is discussed.The role of the government in stimulating and nurturing the innovation process is a controversial one. Proponents of the free enterprise system, many of whom are spokespersons for various industries, have persistently pointed out the deleterious effects of regulation and control on the innovation process. By contrast, advocates of an activist government role are often able to cite the protection of the common welfare as a primary need for government intervention. In truth, the “government” is a patchwork of many governments, operating through many agencies and affecting firms and individuals at several levels and leverage points. The same regulation that has deleterious effects on Industry A may be a stimulus for innovation in Industry B. Even in Industry A, the regulation may act as a force in directing efforts toward certain types of R&D programs that would not otherwise be undertaken.In this paper we examine the specific instances where innovation projects, both product or process types, were affected by government regulation. We also briefly review the critical factors which affect the innovation process and how various governments in industrialized countries have taken actions to influence these factors. Finally, we examine some general guidelines for policymaking purposes. 相似文献

Three main objectives are pursued in this paper. First, we intend to analyze the aggregation problem of directional distance functions from a constructive viewpoint. We provide necessary and sufficient conditions concerning the structural properties of the production technology and of the nature of groups of firms. Indeed, exact additive aggregation holds for a linear technology and for a direction solely defined in the output space. Second, since these conditions are somewhat restrictive, we are interested in providing a measure for the aggregation bias through the relationship between industrial and structural technical efficiency. Finally, we show that this aggregation bias is a lower bound for industrial allocative efficiency. 相似文献
