We analyze the procompetitive effects of dual pricing, that is, input market price discrimination. An upstream firm has an incentive to maintain competition downstream which is realized by selling at an advantageous price to an inefficient downstream firm when discrimination is possible while it would exit under uniform pricing. We augment the exit issue into existing frameworks of Katz (Am Econ Rev 77:154–167, 1987), DeGraba (Am Econ Rev 80:1246–1253, 1990), and Yoshida (Am Econ Rev 90:240–246, 2000) which allows us to show that price discrimination in intermediary goods markets tends to have positive effects on allocative, dynamic and productive efficiency, respectively. In contrast, a discrimination ban tends to facilitate exit of relatively inefficient firms, thereby strengthening downstream market concentration.  相似文献

The article investigates competing understandings of European law. It supports, against the prevailing EU‐centred understanding, an ecumenical concept that embraces EU law, supplementing international instruments, the European Convention on Human Rights and, importantly, various domestic laws enacting or responding to such transnational law, as well as European comparative law. To keep the concept in sync with European politics, it posits a new idea that binds the parts together: to provide for a European legal space rather than further European integration (the ever closer union). This idea can also serve as European law's functional equivalent to forming one legal order. European law thus conceived grasps the puzzling complex of interdependent legal orders, sets a common frame for corresponding reconstructions (European composite constructions, legal pluralism, network theories, federalism or intergovernmentalism) and allows forces with diverging outlooks to meet in one legal field, on one more neutral disciplinary platform. Within this framework, European comparative law finds a new mission as well as a sound legal basis.  相似文献

ABSTRACT

Botswana’s tiny economy is overwhelmingly government-driven and political participation, particularly on the side of the ruling party, is critical for one’s economic survival and prosperity. This has led to enduring intrigue and conflict among the country’s political power elite. Opposition party activists traditionally have embraced leftist policies and claimed to be representing the country’s poor and downtrodden while castigating the ruling Botswana Democratic Party (in power since 1966) of being pro-rich and politically connected business. Ironically, some members of the opposition elite also engage in business ventures with their ruling party counterparts. The scramble for economic opportunities has fuelled debilitating factionalism within both the ruling and opposition parties over the years. In some instances tribalism was mobilised in intra- and inter-party elections for positions of influence even though voters are more interested in service delivery than traditional ethnic issues. Our paper considers the question: ‘Whose interests do Botswana’s politicians represent?’  相似文献

Recent research has demonstrated theimportance of good quality of fiscaladjustments for the success of governmentbudget consolidations. We extend thisapproach to analyze the importance of theeconomic conditions in which fiscalconsolidations are started for theirsuccess. The cyclical positions of thedomestic and international economy, theinitial debt level and the stance of fiscalpolicy in the OECD are all importantdeterminants of the likelihood of fiscalconsolidations. They also affect thegovernment's choice of consolidationstrategy, making them importantdeterminants of the success of fiscalconsolidations. In contrast, the monetarypolicy stance plays only a negligible rolefor fiscal consolidations. We use theanalysis to test for any Maastricht effectson the performance of European governmentsduring the 1990s. Such effects are weak atbest and occurred only during the firsthalf of the decade.  相似文献

A number of options have been proposed to address the expected financing shortfall of Social Security in the next century. Most basic aspects of the various reform proposals are captured by the three options offered by the Advisory Council on Social Security in 1996. Common to all three options is that they would permit either public or private equity investment. This article discusses the economic risks involved in public and private equity investments as a funding solution for Social Security. To quantify the risks involved in equity investment, stochastic simulations are based on the economic assumptions of the 1998 Trustees Report of Old Age and Survivors Insurance and Disability Insurance in combination with different assumptions about the rates of return on bonds and stocks. For public equity investment, financial market risk remains significant for at least 40 years. For individual accounts, I find that the chance of doing worse than with Social Security or of falling into poverty in retirement is generally high, yet varies with income level, gender, family status, and employment history. In general, women, married workers with dependent spouses, or workers with incomplete work histories fare worse than men, single workers, or workers with complete work histories when compared either to the current system or to the poverty line. © 2000 by the Association for Public Policy and Management.  相似文献

This paper explores questions related to the association between social trust and governance. In particular, the paper explores whether the trust-governance association is mainly a reflection of political responsiveness to the demands of the electorate or of the supply of honest politicians and bureaucrats. After outlining some simple theory, the findings suggest that the association reflects a causal influence of both types of trust on institutions of economic-judicial governance while electoral institutions are not associated with social trust. Assessed at the sample mean, the value of social trust under high political competition as evaluated by the compensating income variation is substantial.  相似文献

Quantifying the amount of cortical bone loss is one variable used in histological methods of adult age estimation. Measurements of cortical area tend to be subjective and additional information regarding bone loss is not captured considering cancellous bone is disregarded. We describe whether measuring bone area (cancellous + cortical area) rather than cortical area may improve histological age estimation for the sixth rib. Mid‐shaft rib cross‐sections (n = 114) with a skewed sex distribution were analyzed. Ages range from 16 to 87 years. Variables included: total cross‐sectional area, cortical area, bone area, relative bone area, relative cortical area, and endosteal area. Males have larger mean total cross‐sectional area, bone area, and cortical area than females. Females display a larger mean endosteal area and greater mean relative measure values. Relative bone area significantly correlates with age. The relative bone area variable will provide researchers with a less subjective and more accurate measure than cortical area.  相似文献

Human provenance studies employing isotopic analysis have become an essential tool in forensic and archaeological sciences, with multi-isotope approaches providing more specific location estimates compared to single isotope studies. This study reports on the human provenancing capability of neodymium isotopes (143Nd/144Nd), a relatively conservative tracer in the environment. Neodymium isotope ratios have only recently been determined on human remains due to low concentrations in human dental enamel (ppb range), requiring thermal ionisation mass spectrometry (TIMS) using 1013 Ω resistors. Dental elements (third molars) from 20 individuals born and raised in the Netherlands were analysed for Nd concentration (n = 12) and Nd isotope ratios (n = 15). The geological control on Nd isotope composition was examined using coupled Nd-Sr isotope analysis of the same third molar. Teeth from different geological environments were also analysed (Caribbean, Columbian, and Icelandic, n = 5). Neodymium elemental concentrations in dental elements ranged between 0.1 and 7.9 ppb (median 0.5 ppb). The Dutch 143Nd/144Nd ratios of the provinces of Limburg and Friesland were between 0.5118 and 0.5121, with Dutch 87Sr/86Sr ratios in agreement with the previously established local range (0.708–0.710). The current findings were compared to previously published results on Nd concentration and composition from Dutch individuals. The concentration of Nd and 143Nd/144Nd ratios were weakly correlated (R2 = 0.47, n = 17) in Dutch human dental enamel. The majority (n = 25, 83.3%) of individuals had Nd and Sr isotope values isotopically indistinguishable from the geological environment in which their third molars formed and mineralised. However, the Nd isotope ratios of the Icelandic individual and several Dutch individuals (n = 4) suggested that Nd in enamel is not solely influenced by geological environment. In order for neodymium isotopes to be quantitatively applied in forensic and archaeological settings further analyses of individuals from various geographical regions with well-defined dietary Nd isotope data are required.  相似文献

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation.  相似文献
