Abstract.  This article considers the sale by a research lab of licences for a cost-reducing innovation. The marginal cost of a firm that wins a licence is private information and the acquisition of a licence imposes a negative externality on the other firms. The lab's optimal revenue is determined from a class of mechanisms in which the lab selects the number of licences and the reserve price before the sale. The role of the downstream product market in the determination of the number of licences is analyzed. Furthermore, it is also shown that the optimal reserve price may be zero.  相似文献

The impact of alcohol availability on alcohol-related motor vehicle accidents centres on the sensitivity of consumption to changes in the full price of alcohol – the dollar price of alcohol plus the time and travel costs associated with acquiring alcohol. Reducing the number of licensed alcohol vendors raises the time and travel costs of alcohol; if alcohol consumption is responsive to this price increase, then drinking and driving may decrease. Using data on the 254 counties in the US state of Texas, the results in this paper show that alcohol availability has a significant impact on alcohol-related motor vehicle accidents. Thus, alcohol vendor restrictions can be an important policy tool in reducing such accidents.  相似文献

The author explores the effect of the availability heuristic on large daily stock price changes and on subsequent stock returns. He hypothesizes that if a major positive (negative) stock price move takes place on a day when the stock market index rises (falls), then its magnitude may be amplified by the availability of positive (negative) investment outcomes. In both cases, the availability heuristic may cause price overreaction to the initial company-specific shock, resulting in subsequent price reversal. In line with the hypothesis, the author documents that both positive and negative large price moves accompanied by the same-sign contemporaneous daily market returns are followed by significant reversals on the next 2 trading days and over 5- and 20-day intervals following the event, the magnitude of the reversals increasing over longer postevent windows, while large stock price changes taking place on the days when the market index moves in the opposite direction are followed by nonsignificant price drifts. The results remain robust after accounting for additional company (size, beta, historical volatility) and event-specific (stock's return and trading volume on the event day) factors, and are stronger for small and volatile stocks.  相似文献

This paper estimates the effects of beer prices, alcohol availability, and policies related to driving under the influence of alcohol on drinking and binge drinking among youths and young adults. Data are from a nationally representative survey of students in U.S. colleges and universities. Separate estimates are obtained for underage male and female students, as well as for older male and female students. The estimates indicate that the drinking practices of male college students are generally insensitive to the price of beer. However, underage drinking and binge drinking by female students do respond significantly to price, although both are relatively inelastic. The results also show that strong drunk driving policies targeting youths and young adults significantly reduce drinking and binge drinking by male students. Similarly, these policies reduce drinking among female college students but appear to have little impact on their binge drinking. Instead, the results indicate that many elements of campus life (including participation in a fraternity or sorority, living on campus, and the ready availability of alcoholic beverages) are among the most important determinants of drinking and binge drinking among college students.  相似文献

We analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics (speed and asymmetry of price transmission) using data for a large number of individual gasoline stations in Austria. Specific attention is paid to threshold effects in price adjustment. Our results clearly suggest that the speed of price transmission between the Brent crude oil index and retail diesel prices is higher in a more competitive environment. While evidence on the relationship between local market power and asymmetries in the speed of price adjustment is mixed, our findings regarding asymmetries in price thresholds are clear: in regions where competition from neighbouring rivals is weak and/or consumers’ price elasticity of demand is low (stations located on the highway), positive thresholds significantly exceed negative ones, which corresponds to the ‘rockets and feathers phenomenon’. As expected, we observe that prices are lower in more competitive local markets.  相似文献

We use experiments to examine whether the auctioning of entry rights affects the behaviour of market entrants. Standard economic arguments suggest that the licence fee paid at the auction will not affect pricing since it constitutes a sunk cost. This argument is not uncontested though, and this paper puts it to an experimental test. Our results indicate that an auction of entry licences has a significant positive effect on average prices in oligopoly but not in monopoly. These results are consistent with the conjecture that entry fees induce players to take more risk in pursuit of higher expected profits. In oligopoly, entry fees increase the probability that the market entrants coordinate on a collusive price path. In monopoly, taking more risk does not make sense since average prices are already close to the profit-maximizing price.  相似文献

This study investigates whether recreational boating safety investments and behaviours of current interest are determinants of boating injury severity, and if so, their effects. An ordered probit analysis of 1989–1993 boating accidents suggests that human capital investments in safety, in the form of operator boating experience and formal instruction, reduce both operator and passenger injury severity. Higher levels of operator (passenger) alcohol consumption increase operator (passenger) injury severity, but no relationship was found between operator alcohol consumption and passenger injury severity. At the time a trip is taken, wearing a flotation device has the most efficacious effect on both operator and passenger injury severity. In general, the results support regulatory policies aimed at increasing the use of personal flotation devices as well as reducing alcohol consumption.  相似文献

Drawing on social identity and social impact theory, this paper is the first to investigate the impact of religious preferences on share prices and expected returns at the country level. Using data from 12 European countries, our findings suggest that religion has a significant effect on the share price of companies whose activities are considered unethical, i.e., tobacco manufacturers and alcohol producers. The share price of these companies (called sin stocks) is depressed when they are located in a predominantly Protestant environment (relative to a Catholic environment). With investors in Protestant countries being more sin averse than in Catholic countries, they insist upon higher expected returns on sin stocks. Conversely, religious preferences do not have the same impact on the performance of other companies, e.g. socially responsible companies. Our results are robust to various methodologies and controlling for several firm-specific, industry-specific and country-specific characteristics.  相似文献

In spring 2000, the British government auctioned off licences for Third Generation mobile telecommunications services. In the preparation of the auction, two designs involving each a hybrid of an English and a sealed-bid auction were considered by the government: A discriminatory and a uniform price variant. We report an experiment on these two designs, and also compare the results to those with a pure English auction. Both hybrids are similar in efficiency, revenue differences disappear as bidders get experienced. Compared to the discriminatory format, the pure English auction induces more entry.  相似文献

An empirical analysis is developed that quantifies the impact of different types of traffic incidents on the speed and maximum flow averages of vehicles on a controlled-access highway. The incident types considered include damage to highway infrastructure, vehicle rollover, crashes (into stationary objects), collisions (with moving vehicles), rain, fog, vehicle breakdowns, pedestrians on roadway, etc. Using real-world data from Chile’s most heavily used urban motorway/freeway, estimates of incident impacts on speed are generated using a multiple linear regression model incorporating instrumental variables to correct for endogeneity. Flow results are then generated using the fundamental traffic equation relating speed, flow and density. A ranking of the impacts on highway traffic of the different incident types based on incident frequency as well as impact size demonstrates that for the real case studied, the incidents with the greatest cumulative effect are (in order of magnitude) vehicle breakdown, collisions and rain.  相似文献

Recent years have witnessed an increasing interest in socially responsible investing (SRI), reflecting investors’ growing awareness of social, environmental, ethical and corporate governance issues. At the same time, the effect of oil price shocks on stock price returns has become a prominent issue due to surges in energy prices. Using the Brazilian corporate sustainability index (ISE) as a benchmark for socially responsible investments in the Brazilian stock market, the present study extends the understandings on the impact of oil prices on stock price behaviour, focusing on a new class of assets: those from socially responsible firms. To this end, apart from conventional linear causality approaches, we apply a nonparametric test by Diks and Panchenko (DP) on daily data spanning from January 2008 to December 2015 to test for non-linear causality, before and after controlling for conditional heteroscedasticity. Our findings show that, in spite of their efforts to become more socially responsible, firms that have adhered to the ISE in recent years are influenced by crude oil spot prices, especially the WTI crude. In line with previous studies, we also provide consistent evidence that the Brazilian stock market, as a whole, is associated with the international crude oil market.  相似文献

This paper is concerned with the effects of international trade restriction through quotas. It is shown that a casual relationship exists between the fraction of licences distributed domestically, the terms of trade, and the domestic relative price of the importable.  相似文献

Ascertaining the influencing factors of carbon dioxide emissions in Chinese cities is an important issue for policy-makers. This paper investigates the effect of several determinants on carbon emissions per capita in Chinese cities. Non-normally distributed and heterogeneous features of carbon emissions per capita in Chinese cities are considerably important. The empirical results demonstrate that GDP per capita has an increasingly positive impact on carbon emissions per capita due to the growth in household consumption. Urbanization has a slightly decreasing positive effect on carbon emissions per capita with a quantile increase resulting from continuous highway construction. Industrialization has a decreasing positive effect with carbon emission per capita quantile increases because of increasing energy efficiency and lower costs related to carbon reductions. The population has a decreasing negative effect on carbon emissions because of people’s increasing demand for environmental safety. The distributions of emissions per capita conditional on the 10th and 90th quantiles of independent variables also vary considerably. Specific policy implications are provided based on these results.  相似文献

This article investigates the impact of campus bans on alcohol use and the price of alcohol on college students'drinking intensity. The impact of a campus ban on drinking appears to depend on the ability of students to substitute off-campus access to alcohol for on-campus access. Where few off-campus alternatives exist, campus bans reduce the odds that a student becomes a heavy drinker but have no impact on the odds of transitioning from abstainer to drinker. Where off-campus alternatives are more plentiful, campus bans are less effective. Increasing the price of alcohol appears to be equally effective at reducing the likelihood of drinking and heavy drinking. (JEL)  相似文献

A Federal Highway Bill was enacted in 1987 in response to many state governments' increasing concerns that the 55-mph national maximum speed limit was unduly restrictive. The bill permitted states to raise the maximum speed limit to 65 mph on most rural interstate highways, which historically have been the safest. The state of Indiana reacted promptly to the enabling legislation by raising the maximum speed limit on its rural interstate highways to 65 mph as of June 1, 1987. This paper uses cross-section/time-series data to estimate a model of highway safety. The primary empirical finding is that the higher speed limit on rural interstates has increased the incidence of total and injury interstate accidents but not of fatal interstate accidents. However, for the state as a whole, the relaxed speed limit has reduced total and injury accidents with no effect on fatal accidents. This indicates that the impact of speed limit legislation on non-interstate roads has more than offset its effect on interstate highways.  相似文献

The findings on education expansion and income inequality have important implications for policymakers to implement effective policies to reduce income inequality. This study attempts to explain how education expansion affects income inequality by education distribution and the rate of return to education. We decompose the effect of education expansion on wage gaps into price effect and structure effect. We compare the income inequality from 2002 to 2013 using the Chinese Household Income Project (CHIP) 2002 and CHIP2013 survey data and employ FFL decomposition method. Our findings suggest that income inequality increased in 2013 and that income inequality among the high-income groups increased even more significantly. The structure effect of education expansion on income inequality is negative, when average education increases one year, the income gap between 80th and 20th will decrease 1.2%, in other words, education expansion decreases income inequality by allowing a wide range of individuals to attend college. However, this effect is offset by the price effect, which is positive and much more significant in magnitude. One extra year of average education will increase income gap by 29% which means that the demand for high-skilled labour is increasing faster than the supply and thus lead to the increasing premium for higher education return.  相似文献

Political business cycles are typically linked to the manipulation of fiscal or monetary policy instruments. In a recent article, Imami, Lami and Uberti (ILU) argue that opportunistic politicians may also choose to manipulate non-fiscal/non-monetary policy instruments. Here, we extend ILU’s study using time-series data on mining-sector licensing from post-conflict Kosovo (2001–2018). We find robust evidence that is consistent with electoral opportunism in the allocation of mining permits, despite the checks-and-balance mechanisms introduced by Kosovo’s international administrators in an attempt to reduce the politicisation of licensing. That said, the cycle effect is only observed prior to scheduled, as opposed to early, elections. Disaggregating the data by licence type, in addition, we find that the observed election cycle is driven primarily by the manipulation of licences for the mining of construction materials. We argue that, in the context of post-conflict Kosovo, this is the category of licences whose strategic manipulation offers the greatest pay-off to the incumbent. The results raise some questions about the feasibility of fighting political opportunism (and, relatedly, corruption) by establishing formal check-and-balance mechanisms.  相似文献

Competition in bureaucracy and corruption   总被引:1,自引:0,他引:1  
This paper studies the consequences of introducing competition between bureaucrats. Firms are supposed to invest into eliminating negative externalities of production, while bureaucrats administer the process by issuing licences. Some bureaucrats are corrupt, that is, they issue a licence to any firm in exchange for a bribe. The competition regime is found to create more ex ante incentives for firms to invest, while the monopoly regime is better at implementing ex post allocation, that is, distributing the licences given the firms' investment decisions. Additional results on the effect of punishments and bureaucrats' rotation are provided.  相似文献

In the present paper, we examine the economic growth effects of a limited availability of higher education in a simple endogenous growth model with overlapping generations. It is shown that this limited availability might promote economic growth by increasing aggregate savings. If the supply of human capital is restricted, its price remains high and a large share of aggregate output is distributed to young households, which need to save for their old age. When this growth‐enhancing effect is strong enough, an excessive increase in availability leads to a shortage of investable funds, which substantially reduces economic growth.  相似文献
