We introduce two novel matching mechanisms, Reverse Top Trading Cycles (RTTC) and Reverse Deferred Acceptance (RDA), with the purpose of challenging the idea that the theoretical property of strategy-proofness induces high rates of truth-telling in economic experiments. RTTC and RDA are identical to the celebrated Top Trading Cycles (TTC) and Deferred Acceptance (DA) mechanisms, respectively, in all their theoretical properties except that their dominant-strategy equilibrium is to report one’s preferences in the order opposite to the way they were induced. With the focal truth-telling strategy being out of equilibrium, we are able to perform a clear measurement of how much of the truth-telling reported for strategy-proof mechanisms is compatible with rational behaviour and how much of it is caused by confused decision-makers following a default, focal strategy without understanding the structure of the game. In a school-allocation setting, we find that roughly half of the observed truth-telling under TTC and DA is the result of naïve (non-strategic) behaviour. Only 14–31% of the participants choose actions in RTTC and RDA that are compatible with rational behaviour. Furthermore, by looking at the responses of those seemingly rational participants in control tasks, it becomes clear that most lack a basic understanding of the incentives of the game. We argue that the use of a default option, confusion and other behavioural biases account for the vast majority of truthful play in both TTC and DA in laboratory experiments.
This paper examines market integration between fish species in Europe, taking international market integration into account. Based on Juselius (2006), market integration is found both on the fresh and frozen markets. The Law of One Price is in force on the fresh market within the segments of flatfish and pelagic fish. Assuming transitivity, a loose form of market integration is identified between 13 fresh and seven frozen fish species, and the relative prices are found fairly stable. The policy implication is that catch limitation measures implemented through the Common Fisheries Policy have limited and conditional effects on prices, because of the large size of the market and varying market integration. Therefore, many fishermen are not ‘compensated’ by price increases as a result of catch limitation measures.相似文献
This article examines the effect of financial development on income distribution by analyzing a sample of Latin American countries according to their degree of financial openness for the 1990–2011 period. The period includes the time before and after financial liberalization for most of the countries in the region. As the literature provides inconclusive results regarding the relationship between financial development and income inequality, we aim to determine whether financial openness plays a role in this relationship. Our results provide an explanation for why some countries regardless of their degree of financial openness cannot achieve a reduction in income inequality. 相似文献
The Association of the Southeast Asian Nations (ASEAN) recognizes the role of nonmotorized transport for sustainable urban development in its policy framework. National and local policymakers in Thailand and The Philippines, two tropical countries without a tradition of urban cycling, are increasingly paying attention to cycling as well. This article aims to assess the current situation and progress in cycling, using Bangkok and Metropolitan Manila as case study cities, and to describe the necessary conditions for advancing the significance of cycling in tropical megacities. This is done by operationalizing the so-called Technological Innovation Systems (TIS) framework, which has been used in transition studies since 2008, however, never for cycling. As such this article also “tests” this framework for its application in sustainable transportation. The two case studies are characterized with regards to the current role of cycling in the mobility system, its infrastructure, governance system, and existing research on the potential and barriers. We find that TIS can readily be applied to our cases, with the analysis showing that elements such as knowledge development, actor networks, e-bike adoption, infrastructure, resource mobilization and legitimation are not well developed; on the other hand, flat terrain, attention for cycling for health and environment, heavy congestion, expansion of public transport, growing bike industry, active university communities, and the emergence of advocacy coalitions, could open up opportunities for increasing its modal share. 相似文献
Gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) production from aquaculture has been increasing since the 1990s. Nowadays, about 95% of their production comes from aquaculture. In this study, we analyse if the rapid growth in the aquaculture production of both species has affected the capture fisheries prices of both species. In other words, we investigate if there is market integration between wild and farmed gilthead seabream and European seabass. In order to do this analysis, we use data from the main gilthead seabream and European seabass markets in Spain. The results show that there is no market integration between wild and farmed gilthead seabream and European seabass. This implies that capture fisheries are not affected by increases in the aquaculture production of both species. But gilthead seabream and European seabass aquaculture producers face a smaller demand that explains the difficulties this aquaculture segment is facing. 相似文献
We consider a common indivisible good allocation problem whose popular applications include on‐campus housing, kidney exchange, and school choice. We show that the so‐called New House 4 (NH4) mechanism, which has been in use at MIT since the 1980s, is equivalent to a natural adaptation of the well‐known Gale–Shapley (GS) mechanism. We run two experiments comparing NH4 with the prominently advocated Top Trading Cycles (TTC) mechanism and NH4 with GS. We find that under NH4, the participation rate is significantly higher than under TTC. Based on a new ordinal test of efficiency, NH4 is more likely to Pareto dominate TTC. 相似文献
Following the advice of economists, school choice programs around the world have lately been adopting strategy-proof mechanisms. However, experimental evidence presents a high variation of truth-telling rates for strategy-proof mechanisms. We crash test the connection between the strategy-proofness of the mechanism and truth-telling. We employ a within-subjects design by making subjects take two simultaneous decisions: one with no strategic uncertainty and one with some uncertainty and partial information about the strategies of other players. We find that providing information about the out-of-equilibrium strategies played by others has a negative and significant effect on truth-telling rates. That is, most participants in our within-subjects design try and fail to best-respond to changes in the environment. We also find that more sophisticated subjects are more likely to play the dominant strategy (truth-telling) across all the treatments. These results have potentially important implications for the design of markets based on strategy-proof matching mechanisms. 相似文献
We investigate developments in Danish mortality based on data from 1974–1998 working in a two-dimensional model with chronological time and age as the two dimensions. The analyses are done with non-parametric kernel hazard estimation techniques. The only assumption is that the mortality surface is smooth. Cross-validation is applied for optimal bandwidth selection to ensure the proper amount of smoothing to help distinguishing between random and systematic variation in data. A bootstrap technique is used for construction of pointwise confidence bounds. We study the mortality profiles by slicing up the two-dimensional mortality surface. Furthermore we look at aggregated synthetic population metrics as ‘population life expectancy’ and ‘population survival probability’. For Danish women these metrics indicate decreasing mortality with respect to chronological time. The metrics can not directly be used for prediction purposes. However, we suggest that life insurance companies use the estimation technique and the cross-validation for bandwidth selection when analyzing their portfolio mortality. The non-parametric approach may give valuable information prior to developing more sophisticated prediction models for analysis of economic implications arising from mortality changes. 相似文献
