Consider N independent stochastic processes \((X_i(t), t\in [0,T])\), \(i=1,\ldots , N\), defined by a stochastic differential equation with random effects where the drift term depends linearly on a random vector \(\Phi _i\) and the diffusion coefficient depends on another linear random effect \(\Psi _i\). For these effects, we consider a joint parametric distribution. We propose and study two approximate likelihoods for estimating the parameters of this joint distribution based on discrete observations of the processes on a fixed time interval. Consistent and \(\sqrt{N}\)-asymptotically Gaussian estimators are obtained when both the number of individuals and the number of observations per individual tend to infinity. The estimation methods are investigated on simulated data and show good performances. 相似文献

Firms often choose not to post prices in wholesale markets, and buyers must incur costs to discover prices. Inspired by evidence of customized pricing (e.g., some customers pay up to 70% more than others) and search costs, I estimate a search model to study how personalized pricing impacts efficiency in a wholesale market. I find that price discrimination decreases total surplus by 11.6% and increases the sellers' profits by up to 52.1%. These effects are partially explained by price discrimination softening competition through a decrease in search incentives, illustrating how price discrimination may magnify the efficiency costs of search frictions. 相似文献

The Professional Golfers' Association (PGA) Tour ban on anchored putting (Rule 14‐1b) took effect on January 1, 2016. The ban remains controversial because the governance decision appears to have been made without adequate empirical evidence. Accordingly, to investigate the efficacy of the ban, the impact of using anchored putters on PGA golfers' career success and putting performance was examined. PGA golfers ranked in the top 125 were studied from 2009 to 2015. The analysis revealed an anchored putter offered no unfair advantage with regard to improving players' career success or putting performance when compared with standard putter usage by PGA golfers. 相似文献

Abstract:Since at least the days of Adam Smith there has been the recognition of essentially two forms of capitalism: in their theoretical extremes, one in which private companies determine the conditions of the social provisioning of credit and money, and one in which the State representing the general interest does. As we argue, the zeitgeist of the 1930s was a high water mark in the popular understanding of money and banking and its relationship with society. In contrast, today the general population is woefully ignorant on these points. As we argue, the relationship between financial governance and those governed hinges on the knowledge of the latter. Today’s public discourse reveals a widespread ignorance over financial matters that must accompany a likewise extreme moment of private control over nations’ money and credit. As we argue, the first steps towards a capitalism at the service of humanity and under public control, the first priority is publicly diffused knowledge. 相似文献

We analyze the role of the new goods margin in the Baltic countries’ exports and imports growth during the 1995–2008 period. Using the methodology developed in Kehoe and Ruhl (2013), we define the set of least-traded goods as those that account for the lowest 10% of total exports and imports in 1995, and then trace its growth in several markets including the Baltics’ main trade partners, the European Union and Russia. We find that, on average, by 2008 least-traded goods accounted for nearly 50% of total Baltic exports to their main trade partners. Moreover, we find that increases in the share of least-traded exports coincided with the timing of the trade liberalization reforms implemented by the Baltic countries. Least-traded imports also grew at robust rates, but their growth was lower than that of exports, accounting for slightly less than a quarter of total imports, that is, about half of the exports value. Moreover, we find that the shares of least-traded imports from the EU 15 and from Russia started diverging around the time the Baltic countries joined the EU, with the EU 15 share increasing and the Russian one declining. We also find that the Baltics’ share of least-traded exports outpaced that of other economies in Central and Eastern Europe. Finally, exports of new goods from the Baltic countries suffered noticeably during the Global Financial Crisis. After the crisis ended, the restart in new goods exports growth displayed mixed patterns. 相似文献

The recent publication of the previously secret Agreement on Net Financial Assets (ANFA) directed the public’s attention to the possibility that national central banks could create money through purchases of securities on their own account. This paper provides an overview of the legal foundations for ANFA and shows the varying extent to which the member countries use these regulations. What are the interests, risks and consequences for the countries in crisis and the currency union as a whole? Is the ECB properly monitoring ANFA purchases? Could money creation via ANFA act as an explosive device for the currency union? 相似文献

The goal of the Finnish experiment that started this year is to try to get some evidence on how a new social policy instrument mimicking a basic income would work and what kind of behavioural consequences it would have. At this point, there are many strong arguments being made both in favour of and opposed to basic income. Unfortunately, there are not enough facts yet. The Finnish experiment hopes to change that. 相似文献

The automotive industry is one of the most important industries in Europe. This industry is responsible for 14% of total production and capital investment in the European manufacturing sector, and in Germany the share amounts to 22%. Structural change within this crucial sector is of relevance for the whole economy. Along with alternative propulsion systems such as electromobility, (semi-)autonomous vehicles are one of the big trends in the automotive industry. For established providers, the possibility of disruptive change poses a threat to existing markets, while a gradual introduction of new technologies also increases competition. Nevertheless, with their strong market position in the premium segment and especially their relevant research activities, European and especially German automotive manufacturers are well placed to successfully master the coming challenges in the automotive market. 相似文献

This paper argues that the requirement of measurability (imposed on trading strategies) is indispensable in continuous-time game-theoretic probability. The necessity of the requirement of measurability in measure theory is demonstrated by results such as the Banach–Tarski paradox and is inherited by measure-theoretic probability. The situation in game-theoretic probability turns out to be somewhat similar in that dropping the requirement of measurability allows a trader in a financial security with a non-trivial price path to become infinitely rich while risking only one monetary unit. 相似文献
