Community-Based Tradable Permits for Localized Pollution

This paper considers the assignment of tradable permits—representing property rights of an environmental good—to community members who are harmed by pollution generated by firms. These community members can in turn sell permits to polluters according to their personal preferences. For a special case with a sole household, market transactions between the household and polluters achieve an efficient pollution level. However, for a group of households, the decentralized market solution fails to yield social efficiency because of competitive consumption of the environmental goods. We design a revenue-sharing mechanism akin to unitization, under which market transactions also achieve efficient resource allocation. Importantly, in some cases, efficiency can be achieved even when regulators are ignorant of the private valuation of the environmental good.     

On the test score gap between Roma and non‐Roma students in Hungary and its potential causes

Using unique data from Hungary, the gap in reading and mathematics test scores between Roma and non‐Roma 8th grade students is assessed and a substantial gap between them revealed. Standardized test scores as well as the fraction of students with competences considered inadequate are examined. Regardless of measurement and subject area, the bulk of the gap is explained by social differences in income, wealth and parental education. Using reduced‐form regressions, two major mediating mechanisms are identified: first, on average the home environment of Roma children is less favourable for cognitive development; second, the educational environment of the average Roma student is different from the average non‐Roma student. Comparing students with similar home environments from the same school and class, the ethnic gap in test scores is found to be insignificant. Ethnic differences in the home environment are explained by social disparity, and ethnicity seems to play no additional role in that regard. The unequal distribution of Roma students in schools and classes is found to be explained predominantly by social difference, too, with a significant residual portion, indicating the effect of ethnic segregation.     

BidPacket: trading bandwidth in public spaces

Smart devices such as smartphones and tablets are used extensively in public spaces for the transmission and reception of content in the form of text, photos and streaming videos. Since the bandwidth provided for wireless access is limited in public areas, it becomes an issue for users to gain access to the bandwidth they need at the right times. While an omniscient controller could assign bandwidth to each device on the basis of their needs and overall availability, imperfect information about the instantaneous state of the wifi access patterns and needs of users make for a very inefficient allocation of such bandwidth. This paper provides a solution for bandwidth allocation by creating a market among users of smart devices so that they can bid for extra bandwidth when they need it and sell it when they don’t. They do so by using a virtual currency that is conserved so that each device owner maximizes his own utility. This utility function is composed of both the benefit accrued from accessing bandwidth and the loss of the currency incurred in bidding for such bandwidth. Extensive simulations show that this market-based method outperforms an omniscient model when demand is uncertain, while minimizing bandwidth consumption.     

Assessment of Russian aviation development for long-term prospects with the regard for Arctic developing: reproductive and technological aspects

The article considers the conditions of developing the aviation industry for long-term prospects taking into account factors such as changes in purchasing aviation equipment, progress in developing the Russian aviation market, and works for reconstructing and modernizing transport infrastructure in the Russian Arctic. The author aims to coordinate the Government programs for developing new aviation equipment and equipment for air transport via the program of Arctic Exploration and Development, as it is necessary to integrate various cycle flows with regard to high-tech capital.     

An empirical study of voluntary transfer pricing disclosures in China

This paper empirically investigates the factors that affect the management’s voluntary disclosures of the transfer pricing details of related-party transactions. Using Chinese data from 2004 and 2005, we hypothesize and find that firms that make voluntary disclosures of the pricing methods of related-party transactions are negatively associated with (i) a higher level of earnings management (as captured by abnormal related-party transactions) and (ii) its underlying incentives (as captured by the management’s performance-linked bonuses and the firm’s incentives to achieve earnings targets); further, they are positively associated with (i) a higher percentage of independent directors and (ii) a higher percentage of government ownership. Overall, our findings suggest that earnings management and its incentives, board composition, and ownership structure significantly influence the voluntary disclosure decisions of managers.     

Two-stage DEA: <Emphasis Type="Italic">caveat emptor</Emphasis>

This paper examines the wide-spread practice where data envelopment analysis (DEA) efficiency estimates are regressed on some environmental variables in a second-stage analysis. In the literature, only two statistical models have been proposed in which second-stage regressions are well-defined and meaningful. In the model considered by Simar and Wilson (J Prod Anal 13:49–78, 2007), truncated regression provides consistent estimation in the second stage, where as in the model proposed by Banker and Natarajan (Oper Res 56: 48–58, 2008a), ordinary least squares (OLS) provides consistent estimation. This paper examines, compares, and contrasts the very different assumptions underlying these two models, and makes clear that second-stage OLS estimation is consistent only under very peculiar and unusual assumptions on the data-generating process that limit its applicability. In addition, we show that in either case, bootstrap methods provide the only feasible means for inference in the second stage. We also comment on ad hoc specifications of second-stage regression equations that ignore the part of the data-generating process that yields data used to obtain the initial DEA estimates.     

A proposal for a more objective measure of de facto constitutional constraints

In this paper we propose two new indicators of de facto constitutional constraints. The indicators are based on the presence or the absence of easily observable political events. This makes the proposed measures relatively objective and easy to verify relative to the most widely used indicators of de jure and de facto constitutions. This paper describes the indicators and demonstrates their usefulness for research on economic development.     

Richard H. Thaler — Wirtschaftsnobelpreisträger 2017

Richard H. Thaler was awarded this year’s Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel “for his contributions to behavioural economics”. He studied systematic departures of human behaviour from the standard “homo oeconomicus” assumption. His famous work on boundedly rational behaviour considers both cognitive limitations and limited self-control. The cognitive limitations he studied are in particular the endowment effect, i.e. the observation that individuals assign a higher value to an object if they possess it, and mental accounting, a collection of theories regarding how individuals think about money. Furthermore, he provided path-breaking evidence on the nature of social preferences, which laid the groundwork for the development of several widely used economic theories incorporating altruism, fairness and reciprocity.     

System-dynamic model of regional economy: The case of Rostov oblast

This article presents a method of simulation modeling that is broadly used in regional process studies. Based on this model, we have developed a system of supporting decision-making intended for regional development. Potential development scenarios for the Rostov oblast have been elaborated using statistical data about the region.
