This study back-tests a marginal cost of production model proposed to value the digital currency Bitcoin. Results from both conventional regression and vector autoregression (VAR) models show that the marginal cost of production plays an important role in explaining Bitcoin prices, challenging recent allegations that Bitcoins are essentially worthless. Even with markets pricing Bitcoin in the thousands of dollars each, the valuation model seems robust. The data show that a price bubble that began in the Fall of 2017 resolved itself in early 2018, converging with the marginal cost model. This suggests that while bubbles may appear in the Bitcoin market, prices will tend to this bound and not collapse to zero.  相似文献

The first 150 words of the full text of this article appear below. The year 1982 was not a particularly good period for the worldeconomy. At year's end, the Organization for Economic Cooperationand Development (OECD) revised its growth figures for membernations from slightly over 1% to –0.5%, with some 32 millionunemployed in its 24 member states. In the United States thejobless rate was 11% and 30% of plant capacity stood idle. OttoEckstein found the economy in its worst shape in nearly halfa century. Truly the year belonged to Scrooge. Yet 1982 was a very good year indeed for financial econometrics,the debut of an explosion of activity in the area that continuesvigorously 20 years later, as the emergence of the Journal ofFinancial Econometrics attests. In fact, it can convincinglybe argued that 1982 heralded the beginning of our subject, andperhaps with the recent awarding of the Nobel Prize in Economicsto Robert Engle . . .

The authors estimate gravity models using a large panel of bilateral trade flows across 61 countries between 1980 and 2003, which are applied as a benchmark for the integration of Central and South Eastern European countries with the euro area. They show that a careful examination of the fixed effects of the model is crucial for the proper interpretation of the results. The results suggest that trade integration between most new EU member states and the euro area is already relatively advanced, while the remaining Central and Eastern European countries have significant scope to strengthen trade links with the euro area.  相似文献

Abstract Survey data on Eastern Europe is investigated with respect to two major questions: How do people view the creation of a market economy and how do they assess the speed of economic transformation and privatization. These questions are analyzed by looking at the development over 1990 to 1992 and by performing regressions with a number of demographic variables as regressors. Some findings are that the opposition to the creation of a market economy is increasing over time, that in Hungary and Poland people are quite satisfied with the speed of transformation as compared to Czechs and Slovaks, that the Polish are divided over the speed of privatization, and that the relationship between the speed of transformation and privatization is not considered to be very tight by the respondents.  相似文献

Contrary to most sports fans economists tend to view tournamentsnot only as a mechanism to identify the most able and most talentedathlete(s) but also as an instrument to increase the athletes'effort levels by designing an adequate compensation system thattakes into account the specificities of the contest under consideration.The paper proceeds in two different steps: First, it reviewsthe available evidence on sports contests and identifies somepuzzles that have not yet been resolved in the literature (theempirical separation of selection and incentive effects andthe impact of incentive pay in team settings). Second, it addressesthese puzzles and offers some new evidence supporting the basicassumptions offered by economic theory.  相似文献

An Experimental Bribery Game   总被引:7,自引:0,他引:7  
Essential characteristics of corruption are (1) reciprocityrelationships between bribers and public officials, (2) negativewelfare effects, and (3) high penalties when discovered. Weseparate the influences of these factors in an experiment. Ina two-player game, reciprocation is economically inefficientthrough negative externalities. A control treatment withoutexternalities is also conducted. In a third, so-called suddendeath treatment, corrupt pairs face a low probability of exclusionfrom the experiment without payment. The results show that reciprocitycan establish bribery relationships, where negative externalitieshave no apparent effect. The penalty threat significantly reducescorruption, although discovery probabilities are typically underestimated.  相似文献

Two transitions in the evolution of the social contract are considered, the first from the dominance hierarchies of the great apes (used as a proxy for our prehuman ancestors) to the egalitarian political structure of non-sedentary hunter-gatherer bands, and the second, to the reintroduction of hierarchical institutions of governance, primarily a result of living in fixed settlements after the inception of agriculture. The first transition was a product of biological and cultural evolution, which brought about big brains, language, higher consciousness, and a lower rate of time preference that enabled early man to sustain an egalitarian social contract and thereby escape the domination that confronted his prehuman ancestors. The second transition was a product of cultural evolution alone. The high costs of enforcing the hunter-gatherer social contract caused it to break down and be replaced by hierarchy when the domestication of plants and animals gave rise to a sedentary existence and increased populations. However, it is shown that the very biological and cultural adaptations that made hunter-gatherer egalitarianism possible were a necessary foundation for the spontaneous creation of complex culture and the evolution of institutions that would once again eventually make freedom possible and economic prosperity possible.  相似文献

This paper uses a real option approach to analyze the impact of alternative marketing contracts on the decision to invest in a cooperatively owned hog facility. For the numerical analysis of the impact, this paper uses a simulation method that incorporates early exercise, multiple‐state variables, multi‐choice decisions and temporal optimality. The results show that the option values that stem from the value of waiting to invest and choosing between alternative marketing methods amounts to 20–36% of the initial investment. Further, having an option to choose an alternative marketing method with different risk structure does add to the value of waiting to invest. Having an option to enter a 15‐year marketing contract increases the value of waiting by as much as $117,097 for the pork production example in this paper. Finally, the value of the option to wait is unilaterally lower under a risk‐reducing contract scenario than under a spot market alternative. This could explain the explosion in hog production facility investment during the 1990s when prevalence of contract production increased. Les auteurs ont recouru à l'approche du choix véritable pour analyser l'impact d'autres solutions de mise en marché sur la capacité d'investir ou pas dans un élevage de porcs exploitéà la manière d'une coopérative. Aux fins de l'analyse, on s'est servi d'une méthode de simulation intégrant une brève campagne, de multiples variables d'État, des décisions à choix multiple et des conditions optimales dans le temps. Les résultats indiquent que l'existence d'un choix réel permettant à l'exploitant d'attendre avant d'investir et de sélectionner entre plusieurs méthodes de mise en marché représente 20 à 36 pour cent de l'investissement initial. Par ailleurs, le fait d'avoir accès à une autre méthode de mise en marché, à structure de risque différente, ne donne pas plus de valeur à la capacité d'attendre avant de procéder aux investissements. La possibilité de signer une entente de commercialisation de quinze ans accroît la valeur de l'attente de jusqu'à 117,097 $ pour le type d'élevage porcin retenu comme exemple. Enfin, l'existence d'une entente de commercialisation atténuant les risques réduit unilatéralement la valeur de l'option « attente », comparativement à ce qui se produit quand l'éleveur n'a d'autre choix qu'écouler ses bêtes sur le marché au comptant. Ces résultats pourraient expliquer l'explosion des investissements observée dans le secteur du porc au cours des années 90, où la production sous contrat avait sensiblement augmenté.  相似文献

Asian brands have often struggled to develop quality images. The visual aspects of branding have received little attention on how they might be used to strengthen brand perceptions in Asia. Guidelines for designing visual brand stimuli are developed using evaluations of logos in China and Singapore. There is a significant relationship between design and the responses companies seek, including positive affect, perceptions of quality, recognition, consensus in meaning, and feng shui. How designs are perceived, and their effect on consumer responses, were similar between China and Singapore. Companies are encouraged to leverage design to strengthen their brands. In particular, they should select logo designs that are elaborate, natural, and harmonious as these created positive affect and quality perceptions, clear meaning, true recognition, and feng shui. Many of these relationships hold in the United Sates as well, implying that the visual aspects of brand strategies may accomplish companies' goals across international borders.  相似文献
