Analysis of spectrum auctions in India—An application of the opportunity cost approach to explain large variations in spectrum prices

The remarkable growth of mobile communication has reinforced the significance of the radio spectrum for mobile network operators. The availability of spectrum varies considerably between different countries due to national regulatory decisions. The focus in this paper is on India where operators have access to a limited amount of spectrum. This paper analyses the value of spectrum by estimating the opportunity cost, which is calculated by the savings that can be achieved by acquiring appropriate amount of spectrum rather than investing in additional base stations. The applied approach combines network deployment, user demand levels, cost, and capacity issues, which are integrated in the application in the opportunity cost approach for spectrum. The opportunity cost of spectrum is compared with prices paid at spectrum auctions. The analysis includes a discussion of drivers that determine the willingness to pay for spectrum. The results show that the opportunity cost of spectrum in relation to auction prices is lower than prices operators paid for 3G spectrum in the metro circles (service areas) while the value derived from the opportunity cost is higher than auction prices in the remaining circles.     

Moose Hunting Values in Sweden Now and Two Decades Ago: The Swedish Hunters Revisited

This paper is based on two national contingent valuation studies dealing with the extent and economic values of hunting in Sweden. The first valuation study was conducted in 1987 and the second in 2006. Both the game resource and the hunter community have undergone changes in the two decades covered by the surveys. An important purpose of the latter survey was to repeat relevant parts of the former one, which created a rare opportunity to compare valuations covering a very long time span. Moose hunting value and its determinants were compared between the two studies, showing that significant changes have taken place. Our analysis suggests caution in using results from old contingent valuation studies for e.g. benefits transfer exercises.     

Nationalism and government effectiveness

Nation-building is believed to have a positive influence on economic and political outcomes, especially in countries with ethnically fragmented populations. Yet nationalism, an indicator of successful nation-building, has been empirically linked to protectionism and intolerance, which suggests that dismal performance is a more likely outcome. This paper empirically identifies an inverted U-shaped relationship between nationalism and government effectiveness. The results suggest that the level of nationalism in the population is higher than optimal in most countries. It is further shown that nationalism may mitigate the negative effects of ethnic heterogeneity in former colonies. We find no clear linkages between nationalism and trade openness.     

Governing the transition to low-carbon futures: A critical survey of energy scenarios for 2050

There is a growing scientific consensus that limiting the increase in global average temperature to around 2 °C above pre-industrial levels is necessary to avoid unacceptable impact on the climate system. This requires that the developed countries’ emissions are radically reduced during the next 40 years. Energy scenario studies provide insights on the societal transitions that might be implied by such low-carbon futures, and in this paper we discuss how a greater attention to different governance and institutional issues can complement future scenario exercises. The analysis is based on a critical review of 20 quantitative and qualitative scenario studies, all of relevance for meeting long-term climate policy objectives. The paper: (a) analyzes some key differences in energy technology mixes and primary energy use patterns across these studies; (b) briefly explores the extent and the nature of the societal challenges and policy responses implied; and (c) discusses a number of important implications for the design and scope of future scenario studies. Our review shows that in previous scenario studies the main attention is typically paid to analyzing the impact of well-defined and uniform policy instruments, while fewer studies factor in the role of institutional change in achieving different energy futures. We therefore point towards a number of strategies of integrating issues of transition governance into future scenario analyses, and argue for a closer synthesis of qualitative and quantitative scenario building.     

Farmers' adoption of ecological practices: A systematic literature map

Understanding the factors associated with adoption of ecological farming practices is a well-established topic of interest to agricultural economists. As the transition to more sustainable agriculture has become a policy priority for the European Union, broad and balanced reviews of this literature are important. We develop a systematic map of quantitative observational studies which describes the ecological practice(s) adopted, the frequency of inclusion and significance of a range of independent variables, and how the dependent variable is measured. We also conduct a quality assessment. We find that while socio-demographic variables and farm structural variables are frequently included, they were insignificant more often than they were significant. For behavioural factors we find stronger evidence for the importance of cognitive or attitudinal variables compared to dispositional attitudinal variables. We also find a growing interest in social factors which will be valuable for researchers to explore further and reflect on the policy implications of our findings.     

Exports as an indicator on or promoter of successful swedish manufacturing firms in the 1990s

We study the link between exports and productivity at the firm level. Like in previous studies we get support for the hypothesis that more productive firms self-select into the export market. In addition, and contrary to many of the former studies, we also obtain evidence that exporting further increases firm productivity. Exporting firms appear to have significantly higher productivity than nonexporting. Moreover, exporters—mainly firms that increase their export intensities—have higher output growth than nonexporters. Reallocation of resources between firms may then have contributed to overall manufacturing productivity growth. Hence, we try to quantify the importance of reallocation. JEL no. F10, D24     

Supply Chain Transparency as a Consumer or Corporate Tool: The Case of Nudie Jeans Co

Outsourcing has led both to the embedding of questionable sustainability practices in opaque supply chains and to anti-sweatshop challenges demanding more transparent supply chains. Previous research has argued that supply chain transparency can be both a consumer tool empowering consumers to pressure disclosing firms to improve sustainability conditions and a corporate tool for increasing revenues. Based on a study of the transparency project of Swedish company Nudie Jeans, the authors demonstrate that consumers do not leverage transparency but that transparency improves consumer willingness to buy. In doing this, the authors contribute to the literature in two important ways. First, the authors provide one of the first, if not the first, studies of whether consumers in practice leverage increased supply chain transparency, challenging the previous research claim that supply chain transparency is a useful consumer tool. Second, the authors move beyond studies of purchasing intentions and willingness to buy in experimental settings and confirm that supply chain transparency is a useful corporate tool in practice. The authors conclude by discussing the policy implications of companies being able to use transparency to increase sales without subjecting themselves to increased consumer pressure.     

Capital Budgeting and Political Risk: Empirical Evidence

This paper surveys and investigates Swedish firms' use of capital budgeting techniques for foreign direct investments. We document that the use of the theoretically correct net present value method decreases with the political risk in the host country, and that the use of the Payback method increases with the political risk. We conclude that in the presence of capital market imperfections, unsystematic and country-specific political risks are important. Because these risks are difficult to estimate (rendering high deliberation costs) managers are inclined to use simple rules of thumb for their capital budgeting decisions. Our results can partly explain why surveys find that alternative methods such as the Payback method are frequently used despite their theoretical drawbacks.     

economic and environmental tradeoffs in agricultural sustainability: A Perspective

Concern for the economic and environmental impacts of production systems is at the heart of the debate on agricultural sustainability. Ideally, if a system is to be sustainable, it must also be economically viable, while not adversely affecting the environment. The appropriate balance between environmentally friendly systems and economic returns is not clear, as it depends on the period under consideration and hinges on the perspective used. Current evidence suggests that there are tradeoffs between achieving economic and environmental goals, at least in the short run, with given technology. Analysis suggests progress can be made by identifying agricultural systems and site-specific criteria associated with these systems, which eliminate the clearly unsustainable agricultural practices, rather than seeking a system that is defined as sustainable.The views expressed are those of the authors and do not necessarily represent the policies of the U.S. Department of Agriculture, the Economic Research Service, or the view of other U.S. Department of Agriculture or Economic Research Service staff members.
