International support of climate change policies in developing countries: Strategic, moral and fairness aspects

International transfers in climate policy channeled from the industrialized to the developing world either support the mitigation of climate change or the adaptation to global warming. From a purely allocative point of view, transfers supporting mitigation tend to be Pareto-improving whereas this is not very likely in the case of adaptation support. We illustrate this by regarding transfer schemes currently applied under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto framework.However, if we enrich the analysis by integrating distributional aspects, we find that international adaptation funding may help both the developing and developed world. Interestingly this is not due to altruistic incentives, but due to follow-up effects on international negotiations on climate change mitigation. We argue that the lack of fairness perceived by developing countries in the international climate policy arena can be reduced by the support of adaptation in these countries. As we show - taking into account different fairness concepts - this might raise the prospects of success in international negotiations on climate change. Yet, we find that the influence of transfers may induce different fairness effects on climate change mitigation negotiations to run counter.We discuss whether current transfer schemes under the UNFCCC and the Kyoto framework adequately serve the distributive and allocative objectives pursued in international climate policy.     

The Incidence of Social Security Contributions: An Empirical Analysis

We estimate the effect of social security contributions on wagecosts with sectoral panel data from Eurostat. More than half of the burden of thesecontributions is borne by the employees. Shifting of the burden towards theemployees is more pronounced if the reciprocity between contributions and benefits is stronger. These findings are in line with the predictions derived from anefficient bargaining model.     

Trust and trustworthiness across different age groups

We examine the degree of trust and trustworthiness in an experimental trust game with 662 participants from six different age groups, ranging from 8-year-olds to retired persons. Although both trust and trustworthiness have been identified as fundamental pillars for efficient economic interactions, economic research has devoted little attention to measuring their strength in different age groups. In our experiment subjects interact with members of the same age group. We find that trust increases almost linearly from early childhood to early adulthood, but stays rather constant within different adult age groups. Trustworthiness prevails in all age groups.     

Trade disputes and the implementation of protection under the GATT: an empirical assessment

This paper is a first attempt to empirically determine why countries choose to violate or adhere to GATT rules when making trade policy adjustments between negotiating rounds. We use a previously unexploited set of data in which countries implemented two ‘types’ of protection under the GATT system between 1973 and 1994: (i) ‘legal’ protection in which countries utilized the GATT’s safeguards provisions; and (ii) ‘illegal’ protection in which the protection was provided outside of the safeguards provisions, resulting in a formal trade dispute. We find substantial evidence that concerns for retaliation affect government policy decisions in ways which contribute to the explanation of the existence of trade disputes.     

Empathy with influencers? The impact of the sensory advertising experience on user behavioral responses

Short-form video influencer advertising offers new opportunities for user sensory experience to promote advertising effectiveness and induce positive user responses. This unique means of influencer-generated advertising via short-form videos has not yet been investigated. This study builds on the reciprocity norm of social exchange theory to investigate relationships among ad sensory stimuli (i.e., the sensory advertising experience), the efficacy of influencer advertising (i.e., empathy and altruistic motive), and user behavioral responses (i.e., ad avoidance intention, ad engagement, and purchase intention). It also seeks to shed light on the critical role of perceived influencer effort in these relationships. An empirical study using data from TikTok (Douyin) users and results indicate that sensory advertising experience positively affects user behavioral responses through the serial mediation of empathy and altruistic motive. Additionally, perceived influencer effort is found to be a crucial moderator of the effect of sensory advertising experience on user empathy, which further influences user behavioral responses. The findings provide insight into the persuasion effect and mechanism of short-form video influencer advertising and offer suggestions for advertising campaign designers.     

Social norms and gift behavior: Theory and evidence from Romania

In many developing and transitional countries with limited public income redistribution, inter-household transfers in general, and gifts in particular, are sizable and very important. We use unique Romanian survey data that enables us to isolate pure gifts from other private transfers. We explicitly focus on the importance of community-wide social norms, and find that they indeed play a major role for both the occurrence and the values of gifts. More exactly, our results suggest that the overall predominant gift motive among Romanian households is a norm of reciprocity. Moreover, this norm seems to be dominating for gifts to middle- and high-income households. Even though poor households receive to the same extent, norms of both impure altruism and reciprocity tend to be important. Hence, although the poor may not reciprocate gifts to the same extent as the rich, they still receive, since there is a social norm to give, especially to the poor.     

Optimal remedies in international trade agreements

This paper takes a mechanism-design approach to characterize a politically optimal trade agreement under the assumption that governments have private information about the fluctuating political pressure they face from domestic interest groups to restrict trade. The optimal mechanism under these changing circumstances involves a remedy system for breach of trade agreements that specifies less-than-proportional retaliations against deviating parties. This result is in contrast to the conventional wisdom in the literature regarding the efficiency of the Reciprocity Principle as a rule of renegotiation in trade agreements. I also consider an institutional structure in which only commensurate retaliations are practical but governments can employ a public randomizing device to authorize retaliations. I show that it is optimal to authorize retaliations only randomly. This suggests a role for the WTO dispute settlement process as a public randomizing device.     

Equilibrium vengeance

The efficiency-enhancing role of the vengeance motive is illustrated in a simple social dilemma game in extensive form. Incorporating behavioral noise and observational noise in random interactions in large groups leads to seven continuous families of (short run) Perfect Bayesian equilibria (PBE) that involve both vengeful and non-vengeful types. A new long run evolutionary equilibrium concept, Evolutionary Perfect Bayesian Equilibrium (EPBE), shrinks the equilibrium set to two points. In one EPBE, only the non-vengeful type survives and there are no mutual gains. In the other EPBE, both types survive and reap mutual gains.     

Reciprocity as a key stabilizing norm of interpersonal marketing relationships: Scale development and validation

This study outlines the development and validation of a measure of reciprocity. The definition used to develop the measure extends traditional quid pro quo interpretations to include behavior designed to stabilize relationships in times of exchange breakdown. This includes resisting and not returning harm and making reparation for harm done. Reciprocity is positioned as an important interpersonal norm of stable marketing relationships given recent findings that relationships develop most strongly at the individual level. It is suggested that reciprocity leads to personal well-being; thus providing an additional motivation, over and above economic incentives, to develop and maintain relationships. Results of the scale development tests indicated a valid, two dimensional measure which correlated with key relational variables such as trust, commitment, satisfaction, self-esteem and reduced conflict.
