We show that the entry of private profit-maximising firms makes the consumers worse off compared to having a nationalised monopoly. Such entry increases the nationalised firm’s profit, industry profit, and social welfare, at the expense of the consumers. Our result is important for competition policy.  相似文献

In this paper, we examine the ranking of the maximum-revenue tariff and the optimum-welfare tariff under a linear Cournot oligopoly model without and with free entry of domestic firms. We demonstrate that in a regulated entry oligopoly with asymmetric costs, when the marginal cost of the domestic firms exceeds a critical value, the maximum-revenue tariff is higher than the optimum-welfare tariff. We then show that under free entry of domestic firms with asymmetric costs, when the fixed cost gets larger and the domestic firms become fewer, the difference between the optimum-welfare tariff and the maximum-revenue tariff becomes larger.  相似文献

Sweetness and Power – Public Policies and the ‘Biofuels Frenzy’ In the last decade, there has been a huge policy‐led expansion in biofuels production and consumption. This paper presents some of the findings of a funded research project which has sought to identify the drivers of biofuels policies over this period. It focuses on the EU, US and Brazil which, together, represent about 90 per cent of global biofuels markets. Biofuels policies have three key drivers: as a partial substitute for fossil fuels, to lower greenhouse gas emissions; as a way of improving energy security, by diversifying away from fossil fuels and from the limited number of countries with fossil‐fuel reserves; and as a means of promoting rural development, given the opportunities offered by the production of biofuel feedstocks and their processing into biofuels. One particular challenge for both the EU and US has been to create and sustain a broad coalition of stakeholder interests in support of biofuels and biofuel policies. Both have sought to promote ‘conventional’ biofuels now, whilst trying to aid the development of ‘advanced’ biofuels industries that will address problems with existing technologies. The continued failure to deliver significant quantities of advanced biofuels raises questions for biofuels policymakers going forward, not least dealing with the downsides of conventional biofuels that, so far, have not been mitigated by a successful transition to advanced biofuels.  相似文献

One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. We propose a possible causal mechanism for the forecasting power of the term spread, deriving from the balance sheet management of financial intermediaries and the “risk‐taking channel of monetary policy.” Monetary tightening leads to the flattening of the term spread, reducing net interest margin and credit supply. We provide empirical support for the risk‐taking channel.  相似文献

We investigate a crucial event for job satisfaction: changing one's workplace. For representative German panel data, we show that the reason why the previous employment ended is strongly linked to satisfaction with the new job. Workers initiating a change of employer experience extraordinarily high job satisfaction, though in the short term only. To investigate causality, we exploit the event of plant closure as an exogenous trigger of job switching. In this case, we find no significantly positive effect of job changes on job satisfaction. Our findings complement research on workers’ well‐being and concern labor market policies and human resource management.  相似文献

We examine the impact of the introduction of VIX exchange‐traded products (ETPs) on the information content and pricing efficiency of VIX futures. We document that trades in VIX futures have become less informative and that pricing errors exhibit more persistence after the introduction of VIX ETPs. In addition, we observe that the price process of the VIX futures has become noisier over time. These findings suggest that the introduction of the VIX ETPs had a prominent effect on the properties and dynamics of the VIX futures.  相似文献

ABSTRACT

The benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management.  相似文献

Relative to western Europe, we know very little about the determinants of economic growth at the regional level within socialist Europe. This is somewhat unusual, given that socialist policy-makers have put great emphasis on equitable regional development. This article analyses the regional patterns of growth and divergence in socialist Yugoslavia. New estimates of output and inputs are constructed, and an analysis of output growth, factor accumulation, structural modernization, and productivity is provided. Two novel empirical findings are uncovered. The first is that the sources of growth across the regions were fundamentally different. Total factor productivity was a much more important source of growth in the richer regions than it was in the poorer ones. The second finding is that the source of the regional income divergence lies in the failure of the less developed regions to converge towards the employment rates and total factor productivities of the more developed regions. These failures are interpreted, at least partially, as symptoms of the governing objective and the soft budget constraint of the labour-managed firms that operated in Yugoslavia. It is argued that Yugoslavia's development model was less suited to the pre-conditions that prevailed in the less developed parts of the country.  相似文献

In mixed oligopolies, technology licensing from a cost‐efficient firm to a cost‐inefficient firm has been widely observed. This paper examines the relationship between privatization and licensing (by public or private firms) with the consideration of either a domestic or a foreign private firm. We find that (a) in the case of a domestic private firm, public licensing facilitates privatization, but private licensing hinders privatization; (b) in the case of a foreign private firm, both public and private licensing facilitate privatization. Our results yield important policy implications on privatization.  相似文献

We investigate how a multidimensional disclosure quality (i.e., correlation and precision) determines an optimal information disclosure strategy. We find that, for an infinitely lived, unlevered firm with market perfection, a truth‐telling disclosure is optimal at increasing the expected firm value. However, for a finitely lived, levered firm in the presence of market imperfections (e.g., bankruptcy cost), the optimal disclosure quality depends negatively on the level of imperfections. Once we consider the agency problem, such dependence can become positive, thereby highlighting the importance of a proper managerial‐incentive scheme to align the information disclosure interests of managers and shareholders.  相似文献
