This paper provides theory and evidence on airline bag fees, offering insights into a real‐world case of product unbundling. The theory predicts that an airline's fares should fall when it introduces a bag fee, but that the full‐trip price (the bag fee plus the new fare) could either rise or fall. The empirical evidence presented in the paper provides strong confirmation of the first prediction. The data also suggest that the average fare falls by less than the bag fee itself so that the full price of a trip rises for passengers who choose to check bags. 相似文献

Regulation of relationships between heterogeneous farmers and an aquifer accounting for lag effects 下载免费PDF全文
Cyril Bourgeois Pierre‐Alain Jayet 《The Australian journal of agricultural and resource economics》2016,60(1):39-59
Many environmental problems are due to damage caused by pollutants that accumulate with a time lag following their emission. In this study, we focus on nitrates used in agriculture, which can pollute groundwater many years after their initial application. A dynamic optimal control problem with heterogeneous farmers is proposed. The usual structural parameters such as the discount rate, the natural clearing rate and the lagged time interval between the occurrence of soil‐level pollution and the impact on groundwater are taken into account. We also examine pollution as caused by a continuous set of farms characterised by their individual performance index and by their individual marginal contribution to the pollution. The issue is further investigated by taking account of change in the information context, successively related to perfect information and to asymmetric information. As a result, when the delay between the spreading of N‐fertilizer and the impact on the aquifer increases, that is, the longer the lag, the steady‐state pollution stock and the steady‐state shadow price of the stock both increase. Moreover, we show that the optimal regulation may require a decreasing amount of fertilizer over time, even in the case of initial underpollution. 相似文献

One of the pervasive problems with means‐tested public long‐term care programs is their inability to prevent individuals who could afford private long‐term services from taking advantage of public care. They often manage to elude the means‐test net through ‘strategic impoverishment’. We show in a simple model how this problem comes about, how it affects welfare and how it can be mitigated. 相似文献

This paper examines the generalization of the regulated production function. It characterizes the set of admissible regulatory
constraints that are compatible with the existence of a regulated production function in a sufficiently weak framework to
encompass the usual rate-of-return constraints à la Averch and Johnson and value constraints. 相似文献

Current discussions of climate change are overly focused on the science underpinning environmental impact, with little attention to socioeconomic consequences. The economics of environmental change in particular is insufficiently informed by the lessons that past experiences can yield. Drawing on case studies from Europe and Asia, this special issue underlines the importance of historical context, as well as markets, institutions, technology, and the role of international trade in understanding how economic systems have responded to environmental changes. Past economies have responded dynamically to environmental change rather than simply constrained deterministically by the climatic and ecological events that have engulfed them. 相似文献

Proactive behavior has been indirectly linked to effective selling, an assertion underpinned by a logic, which states that in a world of high competition and choice, the passive, reactive seller is unlikely to do as well as his or her more proactive counterpart. Yet, little direct empirical evidence exists to substantiate this link. In this paper, we address this knowledge gap by describing a study that assesses the effect of proactive behavior on the performance of an industrial sales force. The paper explores the issue of salesperson performance and the construct of proactive behavior (or proactiveness). Using the Proactive Personality (PP) Scale to measure proactiveness and the line manager's subjective evaluation to indicate salesperson performance, it was found that a small but significant relationship exists. The results are discussed, with areas for future research delineated and implications for practitioners explored. 相似文献

We assume that individual voters differ not only according to age but also productivity. In the steady state, workers with wages in the intermediate range join the retired persons to form a majority and vote for a positive level of social security. When a shock decreases population growth, entrenched interests can constrain majority voting decisions and prevent reforms in the name of entitlements. We show that from a Rawlsian viewpoint it may be desirable to rely on these entitlements to protect the low wage earners of the transition generations. However, when the possibility of fixing a basic pension is introduced, it constitutes a better instrument than entitlements. 相似文献

Abstract: This paper assesses the contemporaneous relationship between stock prices, earnings and long-term government bond yields for a large number of countries. The time period of our data spans several decades. In a time series framework our analysis first tests the presence of a long-term contemporaneous relationship between these three variables (the so-called Fed model). Next, we assess if government bond yields play a significant role in the long-run relationship. Our empirical results question the validity of the Fed model in the sense that we show that long-term market movements are mainly driven by the earnings yield and not the differential between bond and earnings yields. As such, our analysis validates the results of Asness (2003) for a much larger collection of countries while using a dynamic time series (cointegration) framework. Finally, we also show that changes in long-term government bond yields have a short-term impact on stock prices. 相似文献

Dual VATs and Cross-Border Trade: Two Problems, One Solution? 总被引:1,自引:0,他引:1
In recent years, two distinct but related questions have been raised with respect to value-added taxes (VATs). Concern has been expressed over whether it is desirable or even possible for both national and subnational governments in federal countries such as India, Argentina, and Russia to impose VATs. One reason for thinking that such subnational VATs are unlikely to be workable on a destination basis is the problem of cross-border trade. Of course, this same problem also arises within the European Union, where there is no EU VAT. Drawing upon Canadian experience, we argue that not only is it possible to have two-tier or dual VATs on a destination basis in a single country but that the existence of dual VATs may help deal with some of the problems of cross-border trade. 相似文献
