This paper studies federal auctions for wildcat leases on the Outer Continental Shelf from 1954 to 1970. These are leases where bidders privately acquire (at some cost) noisy, but equally informative, signals about the amount of oil and gas that may be present. We develop tests of rational and equilibrium bidding in a common values model that are implemented using data on bids and ex post values. We also use data on tract location and ex post values to test the comparative static prediction that bidders may bid less aggressively in common value auctions when they expect more competition. We find that bidders are aware of the "winner's curse" and their bidding is largely consistent with equilibrium.  相似文献

Mergers, brand competition, and the price of a pint   总被引:1,自引:0,他引:1  
Mergers in the UK brewing industry have reduced the number of national brewers from six to four. The number of brands, in contrast, has remained relatively constant. We analyze the effects of mergers on brand competition and pricing. Brand-level demand equations are estimated from a panel of draft beers. To model brand-substitution possibilities, we estimate the matrix of cross-price elasticities semiparametrically. Our structural model is used to assess the strength of brand competition along various dimensions and to evaluate the mergers. In particular, we compute equilibria of pricing games with different numbers of players.  相似文献

This article constitutes a first attempt to systematically map the presence of women in the greatly changing Swedish advertising industry since 1930. The overarching aim of the study is to analyse how the gendered divisions of labour and business changed in relation to both business structure and the overall labour market in Sweden. While we conclude that women constituted around 40–50% of the workforce over time, we see an increase in the shares of women in higher positions and in women who were self-employed and managers. This upturn, however, stabilised during the 1990s. We argue that the changes in gendered divisions of labour and business coincided with a fast-changing business structure. First, the old cartel broke down in the mid-1960s. Then, the number of firms increased quickly during the 1970s and 1980s, and the market share for the largest firms declined. This, in turn, meant new business opportunities for women at the same time as their overall labour market participation increased. The article stresses the importance of both acknowledging women’s presence in the industry development as well as the structures constituting gender divisions.  相似文献

Like most EU and US planning systems, planning in Israel aims to promote certainty regarding future development by employing statutory land-use plans for stabilizing and binding the development of land use. In Israel, district planning from the 1980s onwards took place in the form of long-term land-use plans. However, in practice, Israeli planning witnessed a movement toward discretionary-oriented decision-making, providing for revisions of the land-use plans and subsequently diminishing its efficacy. A pending reform suggests eliminating district land-use plans and absorbing them into national and local plans. Concerning the debate on the future of the Israeli planning system, this research aims to assess the gap between certainty-oriented regulation and actual development, often occurring on a case-by-case basis. Our aim is to evaluate the actual performance of a district land-use plan, focusing particularly on aspects of land-use. Remote Sensing and GIS-based Plan Implementation Evaluation (PIE) analysis was used to test the impact of a comprehensive outline plan for Israel's Central District on the actual development of the built environment. The results show fundamental gaps between the original land-use assignments of the district plan and actual development. The limited effectiveness of regulatory land-use planning for complex, densely populated districts is then discussed in line with the certainty–flexibility dilemma in land-use planning and the structure of planning decision-making in Israel.  相似文献

In this paper we solve an optimal portfolio choice problem to measure the benefits of Treasury Inflation Indexed Securities (TIPS) to investors concerned with maximizing real wealth. We show how the introduction of a real riskless asset completes the investor asset space, by contrasting optimal portfolio allocations with and without such assets. We use historical data to quantify gains from availability of TIPS in the presence of other asset classes such as equities, commodities, and real estate. We draw a distinction between buy-and-hold long-term investors for whom TIPS fully displace nominal risk-free assets and short-term investors for whom TIPS improve the investment opportunity set of real returns. Finally, we show how gains from TIPS are tempered by the availability of alternative assets that covary with inflation, such as gold and real estate.  相似文献

This conceptual paper argues that for sustainable product innovation to make a contribution to addressing sustainability issues, we need to understand not only why consumers adopt sustainable products but also what makes them use these in sustainable way. To explain how specific product features can change the ways in which consumers engage with sustainable products in the adoption and usage phase, we draw on affordance theory. Affordances refer to the potential for agentic action of users in relation to a technological object. We develop a conceptual framework that explains how sustainable product innovation can lead to the design of sustainability affordances that stimulate adoption and sustainable usage. The framework shows how three forms of agency—material, firm, and user agency—interact and together influence a product's sustainability affordances that drive adoption and a change in consumer behavior. The framework explains how trade-offs between a product's environmental features and consumer expectations regarding desired functionalities and user experience can be overcome.  相似文献

Using U.S. firm level panel data we simultaneously assess the contributions to productivity of three potential sources of research and development spillovers: geographic, technological, and product market (“horizontal”). To do so, we construct new measures of geographic proximity based on the distribution of a firm's inventor locations as well as its headquarters. We find that geographic location is important for productivity, as are technology (but not product) spillovers, and that both intra and inter–regional (counties) spillovers matter. The geographic location of a firm's researchers is more important than its headquarters. These benefits may be the reason why local policy makers compete so hard for the location of local R&D labs and high tech workers.  相似文献

From 2007 to 2017, the Agro‐Environmental Protocol of the Sugar and Energy Sector was in force, an agreement between sugarcane mill owners and the State Government of São Paulo, Brazil, proposing to eliminate sugarcane burning as a method to facilitate the harvest. Simultaneously, the sugarcane harvest was becoming widely mechanized while, under the interests of capital accumulation, the mills were entering the information and communication technology era and providing the agricultural processes with more precise and immediate management and technological controls, similar to those implemented in the mills' administrative and industrial operations in the 1990s. Short‐term factors, including environmental factors, favoured sugarcane technological changes. As a result, there was a mass layoff of rural workers and an increasing number of people/workers in agricultural mechanization, transportation and maintenance of machinery and administrative as well. The whole process highlighted the differences between mills, resulting in small and medium sugarcane farmers and mills to become the most impacted, in operational and financial terms, by the accelerating mechanization of the sugarcane industry as a whole.  相似文献

In the automotive industry, the need to move toward more sustainable trajectories of innovation has received much attention. Car manufacturers have started to develop lower emission alternatives for the internal combustion engine, particularly electric, hybrid, and fuel‐cell vehicles. They face the challenge, however, of how to make a potentially disruptive, systemic, and societally embedded technology such as a low‐emission vehicle attractive to mainstream customers. While literature has suggested that companies can empower the initial stages of disruptive innovation by creating protected spaces themselves and/or by taking advantage of such spaces created by public actors, the specific role of these different types of protection levers—private and/or public—has remained unclear. This article therefore investigates to what extent and how private and public protection levers affect firm‐level strategies to increase the attractiveness of disruptive and systemic innovations to mainstream customers. This is explored empirically through a multiple case study of the emergence of low‐emission vehicles within three car manufacturers—Daimler, General Motors, and Toyota—in the context of European, Japanese, and U.S. policies. The empirical analysis is conducted on a data set consisting of more than 9000 articles from two trade magazines, a car magazine and a financial newspaper for the period of 1997–2010. As main findings, the article identifies regulation, tax incentives, and public–private partnerships as the public protection levers that impose or stimulate “new” performance metrics such as fuel economy and vehicle emissions. It also finds that resource allocation, niche occupation, and collaboration‐integration act as the main private protection levers. In addition, two protection levers emerge from the data that are rather prominent in this context: the use of regulation imposing large‐scale commercialization of low‐emission vehicles and dumping of products in the market below cost price. The article concludes with two different protection trajectories—a public protection trajectory and a private protection trajectory—which explain how car manufacturers leverage the various protection levers to deal with disruptive technology. The main implication of the two trajectories is that while the public protection trajectory stalled due to the systemic, socially embedded technological impediments of electric vehicles and fuel‐cell vehicles, the private protection trajectory picked up the remains of the public protection trajectory and has gained momentum, continuing until today.  相似文献

Financially distressed economies inside the European Union (EU) are being blamed for producing a general increase in borrowing costs. This article analyzes the channels of default risk transmission within the EU countries using the information content in the sovereign Credit Default Swap (CDS) market. We proceed in two directions. First, we test the existence of cross-border volatility effects between the central and the peripheral EU countries. Second, we explore the effect of distressed economies on the default and risk premium constituents of sovereign default swaps. We show a significant volatility spillover from distressed to central European Economic and Monetary Union (EMU) economies. This causality pattern leads to a significant impact on the default swap risk premia. On average, the risk premium accounts for approximately 42% of central EMU spreads and 56% of the spreads for those countries outside of the EMU. The peripheral risk also affects the default component of central economies, although its impact is lower.  相似文献
